History.

Origins.

In 1981, Microsoft hired Charles Simonyi, the primary developer of Bravo, the first GUI word processor, which was developed at Xerox PARC. Simonyi started work on a word processor called "Multi-Tool Word" and soon hired Richard Brodie, a former Xerox intern, who became the primary software engineer.  Microsoft announced Multi-Tool Word for Xenix and MS-DOS in 1983. Its name was soon simplified to "Microsoft Word". Free demonstration copies of the application were bundled with the November 1983 issue of "PC World", making it the first to be distributed on-disk with a magazine. That year Microsoft demonstrated Word running on Windows.  Unlike most MS-DOS programs at the time, Microsoft Word was designed to be used with a mouse. Advertisements depicted the Microsoft Mouse, and described Word as a WYSIWYG, windowed word processor with the ability to undo and display bold, italic, and underlined text, although it could not render fonts. It was not initially popular, since its user interface was different from the leading word processor at the time, WordStar. However, Microsoft steadily improved the product, releasing versions 2.0 through 5.0 over the next six years. In 1985, Microsoft ported Word to the classic Mac OS (known as Macintosh System Software at the time). This was made easier by Word for DOS having been designed for use with high-resolution displays and laser printers, even though none were yet available to the general public. Following the precedents of LisaWrite and MacWrite, Word for Mac OS added true WYSIWYG features. It fulfilled a need for a word processor that was more capable than MacWrite. After its release, Word for Mac OS's sales were higher than its MS-DOS counterpart for at least four years.  The second release of Word for Mac OS, shipped in 1987, was named Word 3.0 to synchronize its version number with Word for DOS; this was Microsoft's first attempt to synchronize version numbers across platforms. Word 3.0 included numerous internal enhancements and new features, including the first implementation of the Rich Text Format (RTF) specification, but was plagued with bugs. Within a few months, Word 3.0 was superseded by a more stable Word 3.01, which was mailed free to all registered users of 3.0. After MacWrite Pro was discontinued in the mid-1990s, Word for Mac OS never had any serious rivals. Word 5.1 for Mac OS, released in 1992, was a very popular word processor owing to its elegance, relative ease of use and feature set. Many users say it is the best version of Word for Mac OS ever created.  In 1986, an agreement between Atari and Microsoft brought Word to the Atari ST under the name "Microsoft Write". The Atari ST version was a port of Word 1.05 for the Mac OS and was never updated.  The first version of Word for Windows was released in 1989. With the release of Windows 3.0 the following year, sales began to pick up and Microsoft soon became the market leader for word processors for IBM PC-compatible computers. In 1991, Microsoft capitalized on Word for Windows' increasing popularity by releasing a version of Word for DOS, version 5.5, that replaced its unique user interface with an interface similar to a Windows application. When Microsoft became aware of the Year 2000 problem, it made Microsoft Word 5.5 for DOS available for download free., it is still available for download from Microsoft's web site. In 1991, Microsoft embarked on a project code-named Pyramid to completely rewrite Microsoft Word from the ground up. Both the Windows and Mac OS versions would start from the same code base. It was abandoned when it was determined that it would take the development team too long to rewrite and then catch up with all the new capabilities that could have been added at the same time without a rewrite. Instead, the next versions of Word for Windows and Mac OS, dubbed version 6.0, both started from the code base of Word for Windows 2.0.  With the release of Word 6.0 in 1993, Microsoft again attempted to synchronize the version numbers and coordinate product naming across platforms, this time across DOS, Mac OS, and Windows (this was the last version of Word for DOS). It introduced AutoCorrect, which automatically fixed certain typing errors, and AutoFormat, which could reformat many parts of a document at once. While the Windows version received favorable reviews (e.g., from "InfoWorld"), the Mac OS version was widely derided. Many accused it of being slow, clumsy and memory intensive, and its user interface differed significantly from Word 5.1. In response to user requests, Microsoft offered Word 5 again, after it had been discontinued. Subsequent versions of Word for macOS are no longer direct ports of Word for Windows, instead featuring a mixture of ported code and native code.

Word for Windows.

Word for Windows is available stand-alone or as part of the Microsoft Office suite. Word contains rudimentary desktop publishing capabilities and is the most widely used word processing program on the market. Word files are commonly used as the format for sending text documents via e-mail because almost every user with a computer can read a Word document by using the Word application, a Word viewer or a word processor that imports the Word format (see Microsoft Word Viewer).  Word 6 for Windows NT was the first 32-bit version of the product, released with Microsoft Office for Windows NT around the same time as Windows 95. It was a straightforward port of Word 6.0. Starting with Word 95, releases of Word were named after the year of its release, instead of its version number.  Word 2010 allows more customization of the Ribbon, adds a Backstage view for file management, has improved document navigation, allows creation and embedding of screenshots, and integrates with Word Web App.  Word 2016  Word 2019 adds the dictate function, Old word documents can be transcoded into new documents unlocking word 2019s new features such as converting to webpage and others

Word for Mac.

The Mac was introduced January 24, 1984, and Microsoft introduced Word 1.0 for Mac a year later, on January 18, 1985. The DOS, Mac, and Windows versions are quite different from each other. Only the Mac version was WYSIWYG and used a graphical user interface, far ahead of the other platforms. Each platform restarted its version numbering at "1.0" (https://winworldpc.com/product/microsoft-word/1x-mac). There was no version 2 on the Mac, but version 3 came out on January 31, 1987, as described above. Word 4.0 came out on November 6, 1990, and added automatic linking with Excel, the ability to flow text around graphics and a WYSIWYG page view editing mode.  Word 5.1 for Mac, released in 1992 ran on the original 68000 CPU and was the last to be specifically designed as a Macintosh application. The later Word 6 was a Windows port and poorly received. Word 5.1 continued to run well until the very last Classic MacOS. Many people continue to run Word 5.1 to this day under an emulated Mac classic system for some of its excellent features like document generation and renumbering or to access their old files. In 1997, Microsoft formed the Macintosh Business Unit as an independent group within Microsoft focused on writing software for Mac OS. Its first version of Word, Word 98, was released with Office 98 Macintosh Edition. Document compatibility reached parity with Word 97, and it included features from Word 97 for Windows, including spell and grammar checking with squiggles. Users could choose the menus and keyboard shortcuts to be similar to either Word 97 for Windows or Word 5 for Mac OS.  Word 2001, released in 2000, added a few new features, including the Office Clipboard, which allowed users to copy and paste multiple items. It was the last version to run on classic Mac OS and, on Mac OS X, it could only run within the Classic Environment. Word X, released in 2001, was the first version to run natively on, and required, Mac OS X, and introduced non-contiguous text selection.  Word 2004 was released in May 2004. It included a new Notebook Layout view for taking notes either by typing or by voice. Other features, such as tracking changes, were made more similar with Office for Windows.  Word 2008, released on January 15, 2008, included a Ribbon-like feature, called the Elements Gallery, that can be used to select page layouts and insert custom diagrams and images. It also included a new view focused on publishing layout, integrated bibliography management, and native support for the new Office Open XML format. It was the first version to run natively on Intel-based Macs.  Word 2011, released in October 2010, replaced the Elements Gallery in favor of a Ribbon user interface that is much more similar to Office for Windows, and includes a full-screen mode that allows users to focus on reading and writing documents, and support for Office Web Apps.

Word for Mobile.

Word Mobile is a word processor that allows creating and editing documents. It supports basic formatting, such as bolding, changing font size, and changing colors (from red, yellow, or green). It can add comments, but can't edit documents with tracked changes. It can't open password protected documents, change the typeface, text alignment, or style (normal, heading 1); create bulleted lists; insert pictures; or undo. Word Mobile is neither able to display nor insert footnotes, endnotes, page headers, page footers, page breaks, certain indentation of lists, and certain fonts while working on a document, but retains them if the original document has them. In addition to the features of the 2013 version, the 2007 version on Windows Mobile also has the ability to save documents in the Rich Text Format and open legacy PSW (Pocket Word). Furthermore, it includes a spell checker, word count tool, and a "Find and Replace" command. In 2015, Word Mobile became available for Windows 10 and Windows 10 Mobile on Windows Store.

File formats.

Filename extensions.

Microsoft Word's native file formats are denoted either by a codice_1 or codice_2 filename extension.  Although the codice_1 extension has been used in many different versions of Word, it actually encompasses four distinct file formats:  The newer codice_2 extension signifies the Office Open XML international standard for Office documents and is used by Word 2007 and later for Windows, Word 2008 and later for macOS, as well as by a growing number of applications from other vendors, including OpenOffice.org Writer, an open source word processing program.

Binary formats (Word 97–2007).

During the late 1990s and early 2000s, the default Word document format (.DOC) became a "de facto" standard of document file formats for Microsoft Office users. There are different versions of "Word Document Format" used by default in Word 97–2007. Each binary word file is a Compound File, a hierarchical file system within a file. According to Joel Spolsky, Word Binary File Format is extremely complex mainly because its developers had to accommodate an overwhelming number of features and prioritize performance over anything else.  As with all OLE Compound Files, Word Binary Format consists of "storages", which are analogous to computer folders, and "streams", which are similar to computer files. Each storage may contain streams or other storage. Each Word Binary File must contain a stream called "WordDocument" stream and this stream must start with a File Information Block (FIB). FIB serves as the first point of reference for locating everything else, such as where the text in a Word document starts, ends, what version of Word created the document and other attributes.  Word 2007 and later continue to support the DOC file format, although it is no longer the default.

XML Document (Word 2003).

The.docx "XML " format introduced in Word 2003 was a simple, XML-based format called WordprocessingML.

Cross-version compatibility.

Opening a Word Document file in a version of Word other than the one with which it was created can cause an incorrect display of the document. The document formats of the various versions change in subtle and not so subtle ways (such as changing the font, or the handling of more complex tasks like footnotes). Formatting created in newer versions does not always survive when viewed in older versions of the program, nearly always because that capability does not exist in the previous version. Rich Text Format (RTF), an early effort to create a format for interchanging formatted text between applications, is an optional format for Word that retains most formatting and all content of the original document.

Third-party formats.

Plugins permitting the Windows versions of Word to read and write formats it does not natively support, such as international standard OpenDocument format (ODF) (ISO/IEC 26300:2006), are available. Up until the release of Service Pack 2 (SP2) for Office 2007, Word did not natively support reading or writing ODF documents without a plugin, namely the SUN ODF Plugin or the OpenXML/ODF Translator. With SP2 installed, ODF format 1.1 documents can be read and saved like any other supported format in addition to those already available in Word 2007. The implementation faces substantial criticism, and the ODF Alliance and others have claimed that the third-party plugins provide better support. Microsoft later declared that the ODF support has some limitations.  In October 2005, one year before the Microsoft Office 2007 suite was released, Microsoft declared that there was insufficient demand from Microsoft customers for the international standard OpenDocument format support, and that therefore it would not be included in Microsoft Office 2007. This statement was repeated in the following months. As an answer, on October 20, 2005 an online petition was created to demand ODF support from Microsoft.  In May 2006, the ODF plugin for Microsoft Office was released by the OpenDocument Foundation. Microsoft declared that it had no relationship with the developers of the plugin.  In July 2006, Microsoft announced the creation of the Open XML Translator project – tools to build a technical bridge between the Microsoft Office Open XML Formats and the OpenDocument Format (ODF). This work was started in response to government requests for interoperability with ODF. The goal of project was not to add ODF support to Microsoft Office, but only to create a plugin and an external toolset. In February 2007, this project released a first version of the ODF plugin for Microsoft Word.  In February 2007, Sun released an initial version of its ODF plugin for Microsoft Office. Version 1.0 was released in July 2007.  Microsoft Word 2007 (Service Pack 1) supports (for output only) PDF and XPS formats, but only after manual installation of the Microsoft 'Save as PDF or XPS' add-on. On later releases, this was offered by default.

Features and flaws.

Among its features, Word includes a built-in spell checker, a thesaurus, a dictionary, and utilities for manipulating and editing text. The following are some aspects of its feature set.

Templates.

Several later versions of Word include the ability for users to create their own formatting templates, allowing them to define a file in which the title, heading, paragraph, and other element designs differ from the standard Word templates. Users can find how to do this under the Help section located near the top right corner (Word 2013 on Windows 8).  For example, Normal.dot is the master template from which all Word documents are created. It determines the margin defaults as well as the layout of the text and font defaults. Although normal.dot is already set with certain defaults, the user can change normal.dot to new defaults. This will change other documents which were created using the template, usually in unexpected ways.

Image formats.

Word can import and display images in common bitmap formats such as JPG and GIF. It can also be used to create and display simple line-art. Microsoft Word added support for the common SVG vector image format in 2017 for Office 365 ProPlus subscribers and this functionality was also included in the Office 2019 release.

WordArt.

WordArt enables drawing text in a Microsoft Word document such as a title, watermark, or other text, with graphical effects such as skewing, shadowing, rotating, stretching in a variety of shapes and colors and even including three-dimensional effects. Users can apply formatting effects such as shadow, bevel, glow, and reflection to their document text as easily as applying bold or underline. Users can also spell-check text that uses visual effects, and add text effects to paragraph styles.

Macros.

A Macro is a rule of pattern that specifies how a certain input sequence (often a sequence of characters) should be mapped to an output sequence according to a defined process. Frequently used or repetitive sequences of keystrokes and mouse movements can be automated. Like other Microsoft Office documents, Word files can include advanced macros and even embedded programs. The language was originally WordBasic, but changed to Visual Basic for Applications as of Word 97.  This extensive functionality can also be used to run and propagate viruses in documents. The tendency for people to exchange Word documents via email, USB flash drives, and floppy disks made this an especially attractive vector in 1999. A prominent example was the Melissa virus, but countless others have existed.  These macro viruses were the only known cross-platform threats between Windows and Macintosh computers and they were the only infection vectors to affect any macOS system up until the advent of video codec trojans in 2007. Microsoft released patches for Word X and Word 2004 that effectively eliminated the macro problem on the Mac by 2006.  Word's macro security setting, which regulates when macros may execute, can be adjusted by the user, but in the most recent versions of Word, it is set to HIGH by default, generally reducing the risk from macro-based viruses, which have become uncommon.

Layout issues.

Before Word 2010 (Word 14) for Windows, the program was unable to correctly handle ligatures defined in OpenType fonts. Those ligature glyphs with Unicode codepoints may be inserted manually, but are not recognized by Word for what they are, breaking spell checking, while custom ligatures present in the font are not accessible at all. Since Word 2010, the program now has advanced typesetting features which can be enabled: OpenType ligatures, kerning, and hyphenation. Other layout deficiencies of Word include the inability to set crop marks or thin spaces. Various third-party workaround utilities have been developed.  In Word 2004 for Mac OS X, support of complex scripts was inferior even to Word 97, and Word 2004 did not support Apple Advanced Typography features like ligatures or glyph variants.

Bullets and numbering.

Microsoft Word supports bullet lists and numbered lists. It also features a numbering system that helps add correct numbers to pages, chapters, headers, footnotes, and entries of tables of content; these numbers automatically change to correct ones as new items are added or existing items are deleted. Bullets and numbering can be applied directly to paragraphs and convert them to lists. Word 97 through 2003, however, had problems adding correct numbers to numbered lists. In particular, a second irrelevant numbered list might have not started with number one but instead resumed numbering after the last numbered list. Although Word 97 supported a hidden marker that said the list numbering must restart afterward, the command to insert this marker (Restart Numbering command) was only added in Word 2003. However, if one were to cut the first item of the listed and paste it as another item (e.g. fifth), then the restart marker would have moved with it and the list would have restarted in the middle instead of at the top.  Users can also create tables in "Word". Depending on the version, "Word" can perform simple calculations — along with support for formulas and equations as well.

AutoSummarize.

Available in certain versions of Word (e.g., Word 2007), AutoSummarize highlights passages or phrases that it considers valuable and can be a quick way of generating a crude abstract or an executive summary. The amount of text to be retained can be specified by the user as a percentage of the current amount of text.  According to Ron Fein of the Word 97 team, AutoSummarize cuts wordy copy to the bone by counting words and ranking sentences. First, AutoSummarize identifies the most common words in the document (barring "a" and "the" and the like) and assigns a "score" to each word – the more frequently a word is used, the higher the score. Then, it "averages" each sentence by adding the scores of its words and dividing the sum by the number of words in the sentence – the higher the average, the higher the rank of the sentence. "It's like the ratio of wheat to chaff," explains Fein.  AutoSummarize was removed from Microsoft Word for Mac OS X 2011, although it was present in Word for Mac 2008. AutoSummarize was removed from the Office 2010 release version (14) as well.

Word for the web.

Word for the web is a free lightweight version of Microsoft Word available as part of Office on the web, which also includes web versions of Microsoft Excel and Microsoft PowerPoint.

Password protection.

There are three password types that can be set in Microsoft Word:  The second and the third type of passwords were developed by Microsoft for convenient shared use of documents rather than for their protection. There is no encryption of documents that are protected by such passwords, and the Microsoft Office protection system saves a hash sum of a password in a document's header where it can be easily accessed and removed by the specialized software. "Password to open a document" offers much tougher protection that had been steadily enhanced in the subsequent editions of Microsoft Office.  "Word 95" and all the preceding editions had the weakest protection that utilized a conversion of a password to a 16-bit key.  Key length in "Word 97" and "2000" was strengthened up to 40 bit. However, modern cracking software allows removing such a password very quickly – a persistent cracking process takes one week at most. Use of rainbow tables reduces password removal time to several seconds. Some password recovery software can not only remove a password but also find an actual password that was used by a user to encrypt the document using brute-force attack approach. Statistically, the possibility of recovering the password depends on the password strength.  Word's 2003/XP version default protection remained the same but an option that allowed advanced users choosing a Cryptographic Service Provider was added. If a strong CSP is chosen, guaranteed document decryption becomes unavailable, and therefore a password can't be removed from the document. Nonetheless, a password can be fairly quickly picked with a brute-force attack, because its speed is still high regardless of the CSP selected. Moreover, since the CSPs are not active by default, their use is limited to advanced users only.  Word 2007 offers significantly more secure document protection which utilizes the modern Advanced Encryption Standard (AES) that converts a password to a 128-bit key using a SHA-1 hash function 50000 times. It makes password removal impossible (as of today, no computer that can pick the key in a reasonable amount of time exists), and drastically slows the brute-force attack speed down to several hundreds of passwords per second.  Word's 2010 protection algorithm was not changed apart from the increasing number of SHA-1 conversions up to 100000 times, and consequently, the brute-force attack speed decreased two times more.

Reception.

"BYTE" in 1984 criticized the documentation for Word 1.1 and 2.0 for DOS, calling it "a complete farce". It called the software "clever, put together well, and performs some extraordinary feats", but concluded that "especially when operated with the mouse, has many more limitations than benefits... extremely frustrating to learn and operate efficiently". "PC Magazine" review was very mixed, stating "I've run into weird word processors before, but this is the first time one's nearly knocked me down for the count" but acknowledging that Word's innovations were the first that caused the reviewer to consider abandoning WordStar. While the review cited an excellent WYSIWYG display, sophisticated print formatting, windows, and footnoting as merits, it criticized many small flaws, very slow performance, and "documentation apparently produced by Madame Sadie's Pain Palace". It concluded that Word was "two releases away from potential greatness".  "Compute!'s Apple Applications" in 1987 stated that "despite a certain awkwardness", Word 3.01 "will likely become the major Macintosh word processor" with "far too many features to list here". While criticizing the lack of true WYSIWYG, the magazine concluded that ""Word" is marvelous. It's like a Mozart or Edison, whose occasional gaucherie we excuse because of his great gifts".  "Compute!" in 1989 stated that Word 5.0's integration of text and graphics made it "a solid engine for basic desktop publishing". The magazine approved of improvements to text mode, described the $75 price for upgrading from an earlier version as "the deal of the decade", and concluded that "as a high-octane word processor, "Word" is definitely worth a look".  During the first quarter of 1996, "Microsoft Word" accounted for 80% of the worldwide word processing market.  Despite its commercial success, it has also been argued in the scientific community that "Word" might not be well-suited for large-scale projects with high typographical demands, due to issues such as file compatibility, poor typography, low image quality, and limited feature scalability.

Microsoft Word, also referred to as simply Word, is a word processor developed by Microsoft. It was first released on October 25, 1983 under the name "Multi-Tool Word" for Xenix systems. Subsequent versions were later written for several other platforms including IBM PCs running DOS (1983), Apple Macintosh running the Classic Mac OS (1985), AT&T Unix PC (1985), Atari ST (1988), OS/2 (1989), Microsoft Windows (1989), SCO Unix (1994), and macOS (formerly OS X; 2001).

Microsoft Word je textový procesor od firmy Microsoft, který je součástí kancelářského balíku Microsoft Office. Jeho první verzi vytvořil v roce 1983 programátor Richard Brodie pro společnost IBM (tato verze běžela pod operačním systémem DOS). Následovala mj. verze pro Macintosh (1984) a roku 1989 byl vytvořen první Word běžící pod OS Microsoft Windows.


Early life and education.

Diesel was born in the house Rue Notre Dame de Nazareth No. 38 in Paris, France in 1858 the second of three children of Elise (née Strobel) and Theodor Diesel. His parents were Bavarian immigrants living in Paris. Theodor Diesel, a bookbinder by trade, left his home town of Augsburg, Bavaria, in 1848. He met his wife, a daughter of a Nuremberg merchant, in Paris in 1855 and became a leather goods manufacturer there.  Only few weeks after his birth, Diesel was given away to a Vincennes farmer family, where he spent his first nine months. When he was returned to his family, they moved into the flat 49 in the Rue Fontaineau-Roi. At the time, the Diesel family suffered from financial difficulties, thus young Rudolf Diesel had to work in his father's workshop and deliver leather goods to customers using a barrow. He attended a Protestant-French school and soon became interested in social questions and technology. Being a very good student, 12-year-old Diesel received the Société pour l'Instruction Elémentaire bronze medal and had plans to enter Ecole Primaire Supérieure in 1870.  At the outbreak of the Franco-Prussian War the same year, his family was forced to leave, as were many other Germans. They settled in London, England, where Diesel attended an English school. Before the war's end, however, Diesel's mother sent 12-year-old Rudolf to Augsburg to live with his aunt and uncle, Barbara and Christoph Barnickel, to become fluent in German and to visit the "Königliche Kreis-Gewerbeschule" (Royal County Vocational College), where his uncle taught mathematics.  At the age of 14, Diesel wrote a letter to his parents saying that he wanted to become an engineer. After finishing his basic education at the top of his class in 1873, he enrolled at the newly founded Industrial School of Augsburg. Two years later, he received a merit scholarship from the Royal Bavarian Polytechnic of Munich, which he accepted against the wishes of his parents, who would rather have seen him start to work.

Career.

One of Diesel's professors in Munich was Carl von Linde. Diesel was unable to graduate with his class in July 1879 because he fell ill with typhoid fever. While waiting for the next examination date, he gained practical engineering experience at the Sulzer Brothers Machine Works in Winterthur, Switzerland. Diesel graduated in January 1880 with highest academic honours and returned to Paris, where he assisted his former Munich professor, Carl von Linde, with the design and construction of a modern refrigeration and ice plant. Diesel became the director of the plant one year later.  In 1883, Diesel married Martha Flasche, and continued to work for Linde, gaining numerous patents in both Germany and France.  In early 1890, Diesel moved to Berlin with his wife and children, Rudolf Jr, Heddy, and Eugen, to assume management of Linde's corporate research and development department and to join several other corporate boards there. As he was not allowed to use the patents he developed while an employee of Linde's for his own purposes, he expanded beyond the field of refrigeration. He first worked with steam, his research into thermal efficiency and fuel efficiency leading him to build a steam engine using ammonia vapour. During tests, however, the engine exploded and almost killed him. His research into high compression cylinder pressures tested the strength of iron and steel cylinder heads. One exploded during a run in. He spent many months in a hospital, followed by health and eyesight problems.  Ever since attending lectures of Carl von Linde, Diesel intended designing an internal combustion engine based on the more thermally efficient Carnot cycle. He worked on this idea for a several years, and in 1892, he considered his theory to be completed. The same year, Diesel was given the German patent DRP 67207. In 1893, he published a treatise entitled "Theory and Construction of a Rational Heat-engine to Replace the Steam Engine and The Combustion Engines Known Today", that he had been working on since early 1892. This treatise formed the basis for his work on and invention of the Diesel engine. By summer 1893, Diesel had realised that his initial theory was erroneous, which led him to file another patent application for the corrected theory in 1893.  Diesel understood thermodynamics and the theoretical and practical constraints on fuel efficiency. He knew that as much as 90% of the energy available in the fuel is wasted in a steam engine. His work in engine design was driven by the goal of much higher efficiency ratios. In his engine, fuel was injected at the end of the compression stroke and was ignited by the high temperature resulting from the compression. From 1893 to 1897, Heinrich von Buz, director of MAN SE in Augsburg, gave Rudolf Diesel the opportunity to test and develop his ideas.  The first successful Diesel engine ran in 1897 and is now on display at the German Technical Museum in Munich.  Rudolf Diesel obtained patents for his design in Germany and other countries, including the United States.  He was inducted into the Automotive Hall of Fame in 1978.

Disappearance and death.

On the evening of 29 September 1913, Diesel boarded the GER steamer SS "Dresden" in Antwerp on his way to a meeting of the Consolidated Diesel Manufacturing company in London, England. He took dinner on board the ship and then retired to his cabin at about 10 p.m., leaving word to be called the next morning at 6:15 a.m.; but he was never seen alive again. In the morning his cabin was empty and his bed had not been slept in, although his nightshirt was neatly laid out and his watch had been left where it could be seen from the bed. His hat and neatly folded overcoat were discovered beneath the afterdeck railing.  Ten days later, the crew of the Dutch boat "Coertzen" came upon the corpse of a man floating in the North Sea near Norway. The body was in such an advanced state of decomposition that it was unrecognizable, and they did not bring it aboard. Instead, the crew retrieved personal items (pill case, wallet, I.D. card, pocketknife, eyeglass case) from the clothing of the dead man, and returned the body to the sea. On 13 October, these items were identified by Rudolf's son, Eugen Diesel, as belonging to his father. On 14 October 1913 it was reported that Diesel's body was found at the mouth of the Scheldt by a boatman, but he was forced to throw it overboard because of heavy weather.  There are various theories to explain Diesel's death. Certain people, such as his biographer Grosser, and Hans L. Sittauer (both in 1978) argue that Rudolf Diesel committed suicide. Another line of thought suggests that he was murdered, given his refusal to grant the German forces the exclusive rights to using his invention; indeed, Diesel boarded the SS "Dresden" with the intent of meeting with representatives of the British Royal Navy to discuss the possibility of powering British submarines by Diesel engine – he never made it ashore. Yet, evidence is limited for all explanations, and his disappearance and death remain unsolved.  Shortly after Diesel's disappearance, his wife Martha opened a bag that her husband had given to her just before his ill-fated voyage, with directions that it should not be opened until the following week. She discovered 200,000 German marks in cash (US$1.2 million today) and a number of financial statements indicating that their bank accounts were virtually empty. In a diary Diesel brought with him on the ship, for the date 29 September 1913, a cross was drawn, possibly indicating death.

Legacy.

After Diesel's death, his engine underwent much development and became a very important replacement for the steam piston engine in many applications. Because the Diesel engine required a heavier, more robust construction than a gasoline engine, it saw limited use in aviation. However, the Diesel engine became widespread in many other applications, such as stationary engines, agricultural machines and off-highway machinery in general, submarines, ships, and much later, locomotives, trucks, and in modern automobiles.  The Diesel engine has the benefit of running more fuel-efficiently than gasoline engines due to much higher compression ratios and longer duration of combustion, which means the temperature rises more slowly, allowing more heat to be converted to mechanical work.  Diesel was interested in using coal dust or vegetable oil as fuel, and in fact, his engine was run on peanut oil. Although these fuels were not immediately popular, during 2008 rises in fuel prices, coupled with concerns about oil reserves, have led to the more widespread use of vegetable oil and biodiesel.  The primary fuel used in diesel engines is the eponymous diesel fuel, derived from the refinement of crude oil. Diesel is safer to store than gasoline, because its flash point is approximately 175 °F (79.4 °C) higher, and it will not explode.

Use of vegetable oils as Diesel engine fuel.

In a book titled "Diesel Engines for Land and Marine Work", Diesel said that "In 1900 a small Diesel engine was exhibited by the Otto company which, on the suggestion of the French Government, was run on arachide [peanut] oil, and operated so well that very few people were aware of the fact. The motor was built for ordinary oils, and without any modification was run on vegetable oil. I have recently repeated these experiments on a large scale with full success and entire confirmation of the results formerly obtained."

Rudolf Christian Karl Diesel ( (); 18 March 1858 – 29 September 1913) was a German inventor and mechanical engineer, famous for the invention of the Diesel engine, and for his suspicious death at sea. Diesel was the namesake of the 1942 film "Diesel".

Rudolf Christian Karl Diesel (18. března 1858 Paříž – 30. září 1913) byl německý vynálezce, známý především díky svému motoru.


Origins.

Computational linguistics is often grouped within the field of artificial intelligence but was present before the development of artificial intelligence. Computational linguistics originated with efforts in the United States in the 1950s to use computers to automatically translate texts from foreign languages, particularly Russian scientific journals, into English. Since computers can make arithmetic (systematic) calculations much faster and more accurately than humans, it was thought to be only a short matter of time before they could also begin to process language. Computational and quantitative methods are also used historically in the attempted reconstruction of earlier forms of modern languages and sub-grouping modern languages into language families. Earlier methods, such as lexicostatistics and glottochronology, have been proven to be premature and inaccurate. However, recent interdisciplinary studies that borrow concepts from biological studies, especially gene mapping, have proved to produce more sophisticated analytical tools and more reliable results.  When machine translation (also known as mechanical translation) failed to yield accurate translations right away, automated processing of human languages was recognized as far more complex than had originally been assumed. Computational linguistics was born as the name of the new field of study devoted to developing algorithms and software for intelligently processing language data. The term "computational linguistics" itself was first coined by David Hays, a founding member of both the Association for Computational Linguistics (ACL) and the International Committee on Computational Linguistics (ICCL).  To translate one language into another, it was observed that one had to understand the grammar of both languages, including both morphology (the grammar of word forms) and syntax (the grammar of sentence structure). To understand syntax, one had to also understand the semantics and the lexicon (or 'vocabulary'), and even something of the pragmatics of language use. Thus, what started as an effort to translate between languages evolved into an entire discipline devoted to understanding how to represent and process natural languages using computers.  Nowadays research within the scope of computational linguistics is done at computational linguistics departments, computational linguistics laboratories, computer science departments, and linguistics departments. Some research in the field of computational linguistics aims to create working speech or text processing systems while others aim to create a system allowing human-machine interaction. Programs meant for human-machine communication are called conversational agents.

Approaches.

Just as computational linguistics can be performed by experts in a variety of fields and through a wide assortment of departments, so too can the research fields broach a diverse range of topics. The following sections discuss some of the literature available across the entire field broken into four main area of discourse: developmental linguistics, structural linguistics, linguistic production, and linguistic comprehension.

Developmental approaches.

Language is a cognitive skill that develops throughout the life of an individual. This developmental process has been examined using several techniques, and a computational approach is one of them. Human language development does provide some constraints which make it harder to apply a computational method to understanding it. For instance, during language acquisition, human children are largely only exposed to positive evidence. This means that during the linguistic development of an individual, the only evidence for what is a correct form is provided, and no evidence for what is not correct. This is insufficient information for a simple hypothesis testing procedure for information as complex as language, and so provides certain boundaries for a computational approach to modeling language development and acquisition in an individual.  Attempts have been made to model the developmental process of language acquisition in children from a computational angle, leading to both statistical grammars and connectionist models. Work in this realm has also been proposed as a method to explain the evolution of language through history. Using models, it has been shown that languages can be learned with a combination of simple input presented incrementally as the child develops better memory and longer attention span. This was simultaneously posed as a reason for the long developmental period of human children. Both conclusions were drawn because of the strength of the artificial neural network which the project created.  The ability of infants to develop language has also been modeled using robots in order to test linguistic theories. Enabled to learn as children might, a model was created based on an affordance model in which mappings between actions, perceptions, and effects were created and linked to spoken words. Crucially, these robots were able to acquire functioning word-to-meaning mappings without needing grammatical structure, vastly simplifying the learning process and shedding light on information which furthers the current understanding of linguistic development. It is important to note that this information could only have been empirically tested using a computational approach.  As our understanding of the linguistic development of an individual within a lifetime is continually improved using neural networks and learning robotic systems, it is also important to keep in mind that languages themselves change and develop through time. Computational approaches to understanding this phenomenon have unearthed very interesting information. Using the Price Equation and Pólya urn dynamics, researchers have created a system which not only predicts future linguistic evolution but also gives insight into the evolutionary history of modern-day languages. This modeling effort achieved, through computational linguistics, what would otherwise have been impossible.  It is clear that the understanding of linguistic development in humans as well as throughout evolutionary time has been fantastically improved because of advances in computational linguistics. The ability to model and modify systems at will affords science an ethical method of testing hypotheses that would otherwise be intractable.

Structural approaches.

To create better computational models of language, an understanding of language's structure is crucial. To this end, the English language has been meticulously studied using computational approaches to better understand how the language works on a structural level. One of the most important pieces of being able to study linguistic structure is the availability of large linguistic corpora or samples. This grants computational linguists the raw data necessary to run their models and gain a better understanding of the underlying structures present in the vast amount of data which is contained in any single language. One of the most cited English linguistic corpora is the Penn Treebank. Derived from widely-different sources, such as IBM computer manuals and transcribed telephone conversations, this corpus contains over 4.5 million words of American English. This corpus has been primarily annotated using part-of-speech tagging and syntactic bracketing and has yielded substantial empirical observations related to language structure.  Theoretical approaches to the structure of languages have also been developed. These works allow computational linguistics to have a framework within which to work out hypotheses that will further the understanding of the language in a myriad of ways. One of the original theoretical theses on the internalization of grammar and structure of language proposed two types of models. In these models, rules or patterns learned increase in strength with the frequency of their encounter. The work also created a question for computational linguists to answer: how does an infant learn a specific and non-normal grammar (Chomsky Normal Form) without learning an overgeneralized version and getting stuck? Theoretical efforts like these set the direction for research to go early in the lifetime of a field of study, and are crucial to the growth of the field.  Structural information about languages allows for the discovery and implementation of similarity recognition between pairs of text utterances. For instance, it has recently been proven that based on the structural information present in patterns of human discourse, conceptual recurrence plots can be used to model and visualize trends in data and create reliable measures of similarity between natural textual utterances. This technique is a strong tool for further probing the structure of human discourse. Without the computational approach to this question, the vastly complex information present in discourse data would have remained inaccessible to scientists.  Information regarding the structural data of a language is available for English as well as other languages, such as Japanese. Using computational methods, Japanese sentence corpora were analyzed and a pattern of log-normality was found in relation to sentence length. Though the exact cause of this lognormality remains unknown, it is precisely this sort of information which computational linguistics is designed to uncover. This information could lead to further important discoveries regarding the underlying structure of Japanese and could have any number of effects on the understanding of Japanese as a language. Computational linguistics allows for very exciting additions to the scientific knowledge base to happen quickly and with very little room for doubt.  In recent days, the structural data of languages is available for several languages of the world other than English language. Computational linguistics work is in progress on Sindhi language because the structure, grammar and domain of Sindhi language is different from the other languages of the World. The computational linguistics models for English language are not suitable for Sindhi language. Viewing this, computational linguistics work on Sindhi language has been started properly by developing methods, algorithms, linguistics tools (https://sindhinlp.com/), machine learning models and deep learning models since 2016 to focus and solve the linguistics problems of Sindhi language. This work could lead to further important discoveries regarding the underlying structure of Sindhi, and could have any number of effects on the understanding of Sindhi as a language. Computational linguistics allows for very exciting additions to the scientific knowledge base to happen quickly and with very little room for doubt.  Without a computational approach to the structure of linguistic data, much of the information that is available now would still be hidden under the vastness of data within any single language. Computational linguistics allows scientists to parse huge amounts of data reliably and efficiently, creating the possibility for discoveries unlike any seen in most other approaches.

Production approaches.

The production of language is equally as complex in the information it provides and the necessary skills which a fluent producer must have. That is to say, comprehension is only half the problem of communication. The other half is how a system produces language, and computational linguistics has made interesting discoveries in this area.  In a now famous paper published in 1950 Alan Turing proposed the possibility that machines might one day have the ability to "think". As a thought experiment for what might define the concept of thought in machines, he proposed an "imitation test" in which a human subject has two text-only conversations, one with a fellow human and another with a machine attempting to respond like a human. Turing proposes that if the subject cannot tell the difference between the human and the machine, it may be concluded that the machine is capable of thought. Today this test is known as the Turing test and it remains an influential idea in the area of artificial intelligence.  Some projects are still trying to solve the problem which first started computational linguistics off as its field in the first place. However, methods have become more refined, and consequently, the results generated by computational linguists have become more enlightening. To improve computer translation, several models have been compared, including hidden Markov models, smoothing techniques, and the specific refinements of those to apply them to verb translation. The model which was found to produce the most natural translations of German and French words was a refined alignment model with a first-order dependence and a fertility model. They also provide efficient training algorithms for the models presented, which can give other scientists the ability to improve further on their results. This type of work is specific to computational linguistics and has applications that could vastly improve understanding of how language is produced and comprehended by computers.  Work has also been done in making computers produce language in a more naturalistic manner. Using linguistic input from humans, algorithms have been constructed which are able to modify a system's style of production based on a factor such as linguistic input from a human, or more abstract factors like politeness or any of the five main dimensions of personality. This work takes a computational approach via parameter estimation models to categorize the vast array of linguistic styles we see across individuals and simplify it for a computer to work in the same way, making human-computer interaction much more natural.

Text-based interactive approach.

Many of the earliest and simplest models of human-computer interaction, such as ELIZA for example, involve a text-based input from the user to generate a response from the computer. By this method, words typed by a user trigger the computer to recognize specific patterns and reply accordingly, through a process known as keyword spotting.

Speech-based interactive approach.

Recent technologies have placed more of an emphasis on speech-based interactive systems. These systems, such as Siri of the iOS operating system, operate on a similar pattern-recognizing technique as that of text-based systems, but with the former, the user input is conducted through speech recognition. This branch of linguistics involves the processing of the user's speech as sound waves and the interpreting of the acoustics and language patterns for the computer to recognize the input.

Comprehension approaches.

Much of the focus of modern computational linguistics is on comprehension. With the proliferation of the internet and the abundance of easily accessible written human language, the ability to create a program capable of understanding human language would have many broad and exciting possibilities, including improved search engines, automated customer service, and online education.  Early work in comprehension included applying Bayesian statistics to the task of optical character recognition, as illustrated by Bledsoe and Browing in 1959 in which a large dictionary of possible letters was generated by "learning" from example letters and then the probability that any one of those learned examples matched the new input was combined to make a final decision. Other attempts at applying Bayesian statistics to language analysis included the work of Mosteller and Wallace (1963) in which an analysis of the words used in "The Federalist Papers" was used to attempt to determine their authorship (concluding that Madison most likely authored the majority of the papers).  In 1971 Terry Winograd developed an early natural language processing engine capable of interpreting naturally written commands within a simple rule-governed environment. The primary language parsing program in this project was called SHRDLU, which was capable of carrying out a somewhat natural conversation with the user giving it commands, but only within the scope of the toy environment designed for the task. This environment consisted of different shaped and colored blocks, and SHRDLU was capable of interpreting commands such as "Find a block which is taller than the one you are holding and put it into the box." and asking questions such as "I don't understand which pyramid you mean." in response to the user's input. While impressive, this kind of natural language processing has proven much more difficult outside the limited scope of the toy environment. Similarly, a project developed by NASA called LUNAR was designed to provide answers to naturally written questions about the geological analysis of lunar rocks returned by the Apollo missions. These kinds of problems are referred to as question answering.  Initial attempts at understanding spoken language were based on work done in the 1960s and 1970s in signal modeling where an unknown signal is analyzed to look for patterns and to make predictions based on its history. An initial and somewhat successful approach to applying this kind of signal modeling to language was achieved with the use of hidden Markov models as detailed by Rabiner in 1989. This approach attempts to determine probabilities for the arbitrary number of models that could be being used in generating speech as well as modeling the probabilities for various words generated from each of these possible models. Similar approaches were employed in early speech recognition attempts starting in the late 70s at IBM using word/part-of-speech pair probabilities.  More recently these kinds of statistical approaches have been applied to more difficult tasks such as topic identification using Bayesian parameter estimation to infer topic probabilities in text documents.

Applications.

Modern computational linguistics is often a combination of studies in computer science and programming, math, particularly statistics, language structures, and natural language processing. Combined, these fields most often lead to the development of systems that can recognize speech and perform some task based on that speech. Examples include speech recognition software, such as Apple's Siri feature, spellcheck tools, speech synthesis programs, which are often used to demonstrate pronunciation or help the disabled, and machine translation programs and websites, such as Google Translate.  Computational linguistics can be especially helpful in situations involving social media and the Internet. For example, filters in chatrooms or on website searches require computational linguistics. Chat operators often use filters to identify certain words or phrases and deem them inappropriate so that users cannot submit them. Another example of using filters is on websites. Schools use filters so that websites with certain keywords are blocked from children to view. There are also many programs in which parents use Parental controls to put content filters in place. Computational linguists can also develop programs that group and organize content through Social media mining. An example of this is Twitter, in which programs can group tweets by subject or keywords. Computational linguistics is also used for document retrieval and clustering. When doing an online search, documents and websites are retrieved based on the frequency of unique labels related to what was typed into a search engine. For instance, if a person searches "red, large, four-wheeled vehicle," to find pictures of a red truck, the search engine will still find the information desired by matching words such as "four-wheeled" with "car".  Computational approaches are also important in the study of change over time. This occurs in several ways: through the computational modeling of language families (see further Quantitative comparative linguistics or phylogenetics), through the modeling of changes in sound and meaning

Subfields.

Computational linguistics can be divided into major areas depending upon the medium of the language being processed, whether spoken or textual; and upon the task being performed, whether analyzing language (recognition) or synthesizing language (generation).  Speech recognition and speech synthesis deal with how spoken language can be understood or created using computers. Parsing and generation are sub-divisions of computational linguistics dealing respectively with taking language apart and putting it together. Machine translation remains the sub-division of computational linguistics dealing with having computers translate between languages. The possibility of automatic language translation, however, has yet to be realized and remains a notoriously hard branch of computational linguistics.  Some of the areas of research that are studied by computational linguistics include:

Počítačová nebo komputační lingvistika je obor aplikované lingvistiky věnující se studiu přirozeného jazyka s využitím výpočetní techniky. Někdy se ztotožňuje s matematickou lingvistikou, jindy se považuje za její podobor (společně např. s korpusovou lingvistikou).


Early life.

Charles was born on 17 August 1887, in the Castle of Persenbeug, in Lower Austria. His parents were Archduke Otto Franz of Austria and Princess Maria Josepha of Saxony. At the time, his great-uncle Franz Joseph reigned as Emperor of Austria and King of Hungary. Upon the death of Crown Prince Rudolph in 1889, the Emperor's brother, Archduke Karl Ludwig, was next in line to the Austro-Hungarian throne. However, his death in 1896 from typhoid made his eldest son, Archduke Franz Ferdinand, the new heir presumptive.  Archduke Charles was reared a devout Catholic. He spent his early years wherever his father's regiment happened to be stationed; later on, he lived in Vienna and Reichenau an der Rax. He was privately educated, but, contrary to the custom ruling in the imperial family, he attended a public gymnasium for the sake of demonstrations in scientific subjects. On the conclusion of his studies at the gymnasium, he entered the army, spending the years from 1906-08 as an officer chiefly in Prague, where he studied Law and Political Science concurrently with his military duties.  In 1907, he was declared of age, and Prince Zdenko Lobkowitz was appointed as his chamberlain. During the next few years, he carried out his military duties in various Bohemian garrison towns. Charles' relations with his great-uncle were not intimate, and those with his uncle Franz Ferdinand were not cordial, with the differences between their wives increasing the existing tension between them. For these reasons, Charles, up to the time of the assassination of his uncle in 1914, obtained no insight into affairs of state, but led the life of a prince not destined for a high political position.

Marriage.

In 1911, Charles married Princess Zita of Bourbon-Parma. They had met as children but did not see one another for almost ten years, as each pursued their education. In 1909, his Dragoon regiment was stationed at Brandýs nad Labem in Bohemia, from where he visited his aunt at Franzensbad.  It was during one of these visits that Charles and Zita became reacquainted. Due to Franz Ferdinand's morganatic marriage in 1900, his children were excluded from the succession. As a result, the Emperor pressured Charles to marry. Zita not only shared Charles' devout Catholicism, but also an impeccable royal lineage. Zita later recalled:  Archduke Charles traveled to Villa Pianore, the Italian winter residence of Zita's parents, and asked for her hand; on 13 June 1911, their engagement was announced at the Austrian court. Charles and Zita were married at the Bourbon-Parma castle of Schwarzau in Austria on 21 October 1911. Charles's great-uncle, the 81-year-old Emperor Franz Joseph, attended the wedding. He was relieved to see an heir make a suitable marriage, and was in good spirits, even leading the toast at the wedding breakfast. Archduchess Zita soon conceived a son, and Otto was born 20 November 1912. Seven more children followed in the next decade.

Heir presumptive.

Charles became heir presumptive after the assassination of Archduke Franz Ferdinand in Sarajevo in 1914, the event which precipitated World War I. Only at this time did the old Emperor take steps to initiate the heir-presumptive to his crown in affairs of state. But the outbreak of World War I interfered with this political education. Charles spent his time during the first phase of the war at headquarters at Teschen, but exercised no military influence.  Charles then became a "Feldmarschall" (Field Marshal) in the Austro-Hungarian Army. In the spring of 1916, in connection with the offensive against Italy, he was entrusted with the command of the XX. Corps, whose affections the heir-presumptive to the throne won by his affability and friendliness. The offensive, after a successful start, soon came to a standstill. Shortly afterwards, Charles went to the eastern front as commander of an army operating against the Russians and Romanians.

Reign.

Charles succeeded to the thrones in November 1916 after the death of his grand-uncle, Emperor Franz Joseph. On 2 December 1916, he assumed the title of Supreme Commander of the whole army, succeeding Archduke Friedrich. His coronation as King of Hungary occurred on 30 December. In 1917, Charles secretly entered into peace negotiations with France. He employed his brother-in-law, Prince Sixtus of Bourbon-Parma, an officer in the Belgian Army, as intermediary. However, the Allies insisted on Austrian recognition of Italian claims to territory and Charles refused, so no progress was made. Foreign minister Graf Czernin was only interested in negotiating a general peace which would include Germany, Charles himself went much further in suggesting his willingness to make a separate peace. When news of the overture leaked in April 1918, Charles denied involvement until French Prime Minister Georges Clemenceau published letters signed by him. This led to Czernin's resignation, forcing Austria-Hungary into an even more dependent position with respect to its seemingly wronged German ally.  The Austro-Hungarian Empire was wracked by inner turmoil in the final years of the war, with much tension between ethnic groups. As part of his Fourteen Points, U.S. President Woodrow Wilson demanded that the Empire allow for autonomy and self-determination of its peoples. In response, Charles agreed to reconvene the Imperial Parliament and allow for the creation of a confederation with each national group exercising self-governance. However, the ethnic groups fought for full autonomy as separate nations, as they were now determined to become independent from Vienna at the earliest possible moment.  The new foreign minister Baron Istvan Burián asked for an armistice 14 October based on the Fourteen Points, and two days later Charles issued a proclamation that radically changed the nature of the Austrian state. The Poles were granted full independence with the purpose of joining their ethnic brethren in Russia and Germany in a Polish state. The rest of the Austrian lands were transformed into a federal union composed of four parts: German, Czech, South Slav, and Ukrainian. Each of the four parts was to be governed by a federal council, and Trieste was to have a special status. However, United States Secretary of State Robert Lansing replied four days later that the Allies were now committed to the causes of the Czechs, Slovaks and South Slavs. Therefore, autonomy inside the Empire for the nationalities was no longer enough. In fact, a Czechoslovak provisional government had joined the Allies 14 October, and the South Slav national council declared an independent South Slav state 29 October 1918.

Trialism and Croatia.

From the beginning of his reign, Karl favored the creation of a third Croatian political entity in the Empire, in addition to Austria and Hungary. In his Croatian coronation oath in 1916, he recognized the union of the Triune Kingdom of Croatia, Dalmatia and Slavonia with Rijeka and during his short reign supported trialist suggestions from the Croatian Sabor and Ban, but the suggestions were always vetoed by the Hungarian side which did not want to share power with other nations. After Emperor Karl's manifesto of 14 October 1918 was rejected by the declaration of the National Council in Zagreb. President of the Croatian pro-monarchy political party Pure Party of Rights Dr. Aleksandar Horvat, with other parliament members and generals went to visit the emperor on 21 October 1918 in Bad Ischl, where the emperor agreed and signed the trialist manifesto under the proposed terms set by the delegation, on the condition that the Hungarian part does the same since he swore an oath on the integrity of the Hungarian crown. The delegation went the next day to Budapest where it presented the manifesto to Hungarian officials and Council of Ministers who signed the manifesto and released the king from his oath, creating a third Croatian political entity (Zvonimir's kingdom). After the signing, two parades were held in Zagreb, one for the ending of the K.u.K. monarchy, which was held in front of the Croatian National Theater, and another one for saving the trialist monarchy. The last vote for the support of the trialist reorganization of the empire was, however, too late. On 29 October 1918, the Croatian Sabor (parliament) ended the union and all ties with Hungary and Austria, proclaimed the unification of all Croatian lands and entered the State of Slovenes, Croats and Serbs. The curiosity is that no act of Sabor dethroned King Karl IV, nor did it acknowledge the entering in a state union with Serbia, which is today mentioned in the preamble of the Constitution of Croatia.  The Lansing note effectively ended any efforts to keep the Empire together. One by one, the nationalities proclaimed their independence; even before the note the national councils had been acting more like provisional governments. Charles' political future became uncertain. On 31 October, Hungary officially ended the personal union between Austria and Hungary. Nothing remained of Charles' realm except the predominantly German-speaking Danubian and Alpine provinces, and he was challenged even there by the German Austrian State Council. His last Austrian prime minister, Heinrich Lammasch, advised him that he was in an impossible situation, and his best course was to temporarily give up his right to exercise sovereign power.

Proclamations of November 1918.

On the day of the Armistice of 11 November 1918, Charles issued a carefully worded proclamation in which he recognized the Austrian people's right to determine the form of the state and "relinquish[ed] every participation in the administration of the State." He also released his officials from their oath of loyalty to him. On the same day, the Imperial Family left Schönbrunn Palace and moved to Castle Eckartsau, east of Vienna. On 13 November, following a visit with Hungarian magnates, Charles issued a similar proclamation—the Eckartsau Proclamation—for Hungary.  Although it has widely been cited as an "abdication", the word itself was never used in either proclamation. Indeed, he deliberately avoided using the word "abdication" in the hope that the people of either Austria or Hungary would vote to recall him. Privately, Charles left no doubt that he believed himself to be the rightful emperor. He wrote to Friedrich Gustav Piffl, the Archbishop of Vienna: "I did not abdicate, and never will [...] I see my manifesto of 11 November as the equivalent to a cheque which a street thug has forced me to issue at gunpoint [...] I do not feel bound by it in any way whatsoever." Instead, on 12 November, the day after he issued his proclamation, the independent Republic of German-Austria was proclaimed, followed by the proclamation of the First Hungarian Republic on 16 November. An uneasy truce-like situation ensued and persisted until 23 to 24 March 1919, when Charles left for Switzerland, escorted by the commander of the small British guard detachment at Eckartsau, Lieutenant Colonel Edward Lisle Strutt.  As the imperial train left Austria on 24 March, Charles issued another proclamation in which he confirmed his claim of sovereignty, declaring that "whatever the national assembly of German Austria has resolved with respect to these matters since 11 November is null and void for me and my House." The newly established republican government of Austria was not aware of this "Manifesto of Feldkirch" at this time—it had been dispatched only to King Alfonso XIII of Spain and to Pope Benedict XV through diplomatic channels—and politicians in power were irritated by the Emperor's departure without explicit abdication.  The Austrian Parliament responded on 3 April with the Habsburg Law, which dethroned and banished the Habsburgs. Charles was barred from ever returning to Austria. Other male Habsburgs could only return if they renounced all intentions of reclaiming the throne and accepted the status of ordinary citizens. Another law passed on the same day abolished all nobility in Austria. In Switzerland, Charles and his family briefly took residence at Castle Wartegg near Rorschach at Lake Constance, and later moved to Château de Prangins at Lake Geneva on 20 May.

Attempts to reclaim throne of Hungary.

Encouraged by Hungarian royalists ("legitimists"), Charles sought twice in 1921 to reclaim the throne of Hungary, but failed largely because Hungary's regent, Admiral Miklós Horthy (the last commander of the Imperial and Royal Navy), refused to support Charles' restoration. Horthy's action was declared "treasonous" by royalists. Critics suggest that Horthy's actions were more firmly grounded in political reality than those of Charles and his supporters. Indeed, neighbouring countries had threatened to invade Hungary if Charles tried to regain the throne. Later in 1921, the Hungarian parliament formally nullified the Pragmatic Sanction, an act that effectively dethroned the Habsburgs.

Exile in Madeira, Portugal and death.

After the second failed attempt at restoration in Hungary, Charles and his pregnant wife Zita were arrested and quarantined at Tihany Abbey. On 1 November 1921 they were taken to the Hungarian Danube harbour city of Baja, were forced to board the British monitor HMS "Glowworm", and there removed to the Black Sea where they were transferred to the light cruiser. On 19 November 1921 they arrived at their final exile, the Portuguese island of Madeira. Determined to prevent a third restoration attempt, the Council of Allied Powers had agreed on Madeira because it was isolated in the Atlantic Ocean and easily guarded.  The couple and their children, who joined them on 2 February 1922, lived first at Funchal at the Villa Vittoria, next to Reid's Hotel, and later moved to Quinta do Monte. Compared to the imperial glory in Vienna and even at Eckartsau, conditions there were certainly impoverished.  Charles did not leave Madeira. On 9 March 1922 he had caught a cold in town, which developed into bronchitis and subsequently progressed to severe pneumonia. Having suffered two heart attacks, he died of respiratory failure on 1 April, in the presence of his wife (who was pregnant with their eighth child) and nine-year-old former Crown Prince Otto, remaining conscious almost until his last moments. His last words to his wife were "I love you so much." His remains except for his heart are still on the island, resting in state in a chapel devoted to the Emperor in the Church of Our Lady of The Hill (Igreja de Nossa Senhora do Monte), in spite of several attempts to move them to the Habsburg Crypt in Vienna. His heart and the heart of his wife are entombed in Muri Abbey, Switzerland.

Legacy.

Historians have been mixed in their evaluations of Charles and his reign. In the interwar years he was celebrated in Austria as a military hero. When Nazi Germany took over it made his memory into that of a traitor. For decades after 1945, both popular interest and academic interest practically disappeared. Attention has slowly returned.  Helmut Rumpler, the head of the Habsburg commission of the Austrian Academy of Sciences, described Charles as "a dilettante, far too weak for the challenges facing him, out of his depth, and not really a politician." Others have seen Charles as a brave and honourable figure who tried to stop the war in which his Empire was doing so poorly. The English Neo-Jacobite writer, Herbert Vivian, wrote: Karl was a great leader, a Prince of peace, who wanted to save the world from a year of war; a statesman with ideas to save his people from the complicated problems of his Empire; a King who loved his people, a fearless man, a noble soul, distinguished, a saint from whose grave blessings come. Anatole France, the French novelist, stated: This war without end is criminal. What is abominable is that they do not want to end it. No, they do not want. Do not try to tell me that there was no way to end it. Emperor Charles offered peace; he is the only decent man to have appeared in this war, and he was not listened to. There was, through him, a chance that could have been seized... Clemenceau called the emperor a "rotten conscience," it's ignoble. Emperor Charles sincerely wanted peace, and therefore was despised by the whole world. [...] A king of France, yes a king, would have had pity on our poor, exhausted, bloodlet nation. However democracy is without a heart and without entrails. When serving the powers of money, it is pitiless and inhuman.  Paul von Hindenburg, the German commander in chief, commented in his memoirs:He tried to compensate for the evaporation of the ethical power which emperor Franz Joseph had represented by offering völkisch reconciliation. Even as he dealt with elements who were sworn to the goal of destroying his empire he believed that his acts of political grace would affect their conscience. These attempts were totally futile; those people had long ago lined up with our common enemies, and were far from being deterred.

Beatification.

Catholic Church leaders have praised Charles for putting his Christian faith first in making political decisions, and for his role as a peacemaker during the war, especially after 1917. They have considered that his brief rule expressed Catholic social teaching, and that he created a social legal framework that in part still survives.  Pope John Paul II declared Charles "Blessed" in a beatification ceremony held on 3 October 2004, and stated:  Pope Benedict XV's peace plan consisted of seven principal elements: (1) the moral force of right... be substituted for the material force of arms, (2) there must be simultaneous and reciprocal diminution of armaments, (3) a mechanism for international arbitration must be established, (4) true liberty and common rights over the sea should exist, (5) there should be a renunciation of war indemnities, (6) occupied territories should be evacuated, and (7) there should be an examination of rival claims. To summarize, the best outcome to the war, according to Pope Benedict XV, was an immediate restoration to the status quo without reparations or any form of forced demands. Although the plan seemed unattainable due to the severity of the war thus far, it had been appealing to the Catholic Emperor Charles I, who could have seen it as his duty as Apostolic King of Hungary to carry out the Church's will, or as a way to preserve his throne in the years to come. Pope John Paul II was also beatifying and canonizing a significantly larger number of individuals as saints during the later part of his pontificate, which could have influenced his decision to beatify Emperor Charles I as Charles the Blessed.  From the beginning, Emperor Charles conceived of his office as a holy service to his people. His chief concern was to follow the Christian vocation to holiness also in his political actions. For this reason, his thoughts turned to social assistance.  The "cause" or campaign for his canonization began in 1949, when the testimony of his holiness was collected in the Archdiocese of Vienna. In 1954, the cause was opened and he was declared "servant of God", the first step in the process. At the beginning of the cause for canonization in 1972 his tomb was opened and his body was discovered to be incorrupt.  The League of Prayers established for the promotion of his cause has set up a website, and Cardinal Christoph Schönborn of Vienna has sponsored the cause.

Hymn.

There is a hymn being used in the anglophone world as a devotion to Blessed Karl. The hymn, only being one simple stanza, was written by Jamie McGowan, a promoter of Blessed Karl's cause in Scotland. The use of the hymn is set to the Kaiserhymne, which was the national anthem of Austria-Hungary at the time Karl was in power.

Origins.

The earliest evidence for a connecting rod appears in the late 3rd century AD Roman Hierapolis sawmill. It also appears in two 6th century Eastern Roman saw mills excavated at Ephesus respectively Gerasa. The crank and connecting rod mechanism of these Roman watermills converted the rotary motion of the waterwheel into the linear movement of the saw blades.  In Renaissance Italy, the earliest evidence of a − albeit mechanically misunderstood − compound crank and connecting-rod is found in the sketch books of Taccola. A sound understanding of the motion involved displays the painter Pisanello (d. 1455) who showed a piston-pump driven by a water-wheel and operated by two simple cranks and two connecting-rods.  By the 16th century, evidence of cranks and connecting rods in the technological treatises and artwork of Renaissance Europe becomes abundant; Agostino Ramelli's "The Diverse and Artifactitious Machines" of 1588 alone depicts eighteen examples, a number which rises in the "Theatrum Machinarum Novum" by Georg Andreas Böckler to 45 different machines.  An early documentation of the design occurred sometime between 1174—1206 AD in the Artuqid State (modern Turkey), when inventor Al-Jazari described a machine which incorporated the connecting rod with a crankshaft to pump water as part of a water-raising machine.

Steam engines.

The 1712 Newcomen atmospheric engine (the first steam engine) used chain drive instead of a connecting rod, since the piston only produced force in one direction. However, most steam engines after this are double-acting, therefore the force is produced in both directions, leading to the use of a connecting rod. The typical arrangement uses a large sliding bearing block called a crosshead with the hinge between the piston and connecting rod placed outside the cylinder, requiring a seal around the piston rod. In a steam locomotive, the cranks are usually mounted directly on the driving wheels. The connecting connecting rod is used between the between the crank pin on the wheel and the crosshead (where it connects to the piston rod). The equivalent connecting rods on diesel locomotives are called'side rods' or 'coupling rods'. On smaller steam locomotives, the connecting rods are usually of rectangular cross-section, however marine-type rods of circular cross-section have occasionally been used.  On paddle steamers, the connecting rods are called 'pitmans' (not to be mistaken for pitman arms).

Internal combustion engines.

A connecting rod for an internal combustion engine consists of the 'big end', 'rod' and'small end'. The small end attaches to the gudgeon pin (also called 'piston pin' or 'wrist pin'), which can swivel in the piston. Typically, the big end connects to the crankpin using a plain bearing to reduce friction; however some smaller engines may instead use a rolling-element bearing, in order to avoid the need for a pumped lubrication system.  Typically there is a pinhole bored through the bearing on the big end of the connecting rod so that lubricating oil squirts out onto the thrust side of the cylinder wall to lubricate the travel of the pistons and piston rings.  A connecting rod can rotate at both ends, so that the angle between the connecting rod and the piston can change as the rod moves up and down and rotates around the crankshaft.

Materials.

In mass-produced automotive engines, the connecting rods are most usually made of steel. In high performance applications, "billet" connecting rods can be used, which are machined out of a solid billet of metal, rather than being cast or forged.  Other materials include T6-2024 aluminium alloy or T651-7075 aluminium alloy, which are used for lightness and the ability to absorb high impact at the expense of durability. Titanium is a more expensive option which reduces the weight. Cast iron can be used for cheaper, lower performance applications such as motor scooters.

Failure during operation.

During each rotation of the crankshaft, a connecting rod is often subject to large and repetitive forces: shear forces due to the angle between the piston and the crankpin, compression forces as the piston moves downwards, and tensile forces as the piston moves upwards. These forces are proportional to the engine speed (RPM) squared.  Failure of a connecting rod, often called "throwing a rod", is one of the most common causes of catastrophic engine failure in cars, frequently driving the broken rod through the side of the crankcase and thereby rendering the engine irreparable. Common causes of connecting rod failure are tensile failure from high engine speeds, the impact force when the piston hits a valve (due to a valvetrain problem), rod bearing failure (usually due to a lubrication problem, or incorrect installation of the connecting rod.

Cylinder wear.

The sideways force exerted on the piston through the connecting rod by the crankshaft can cause the cylinders to wear into an oval shape. This significantly reduces engine performance, since the circular piston rings are unable to properly seal against the oval-shaped cylinder walls.  The amount of sideways force is proportional to the angle of the connecting rod, therefore longer connecting rods will reduce the amount of sideways force and engine wear. However, the maximum length of a connecting rod is constrained by the engine block size; the stroke length plus the connecting rod length must not result in the piston travelling past the top of the engine block.

Master-and-slave rods.

Radial engines typically use master-and-slave connecting rods, whereby one piston (the uppermost piston in the animation), has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod.  Multi-bank engines with many cylinders, such as V12 engines, have little space available for many connecting rod journals on a limited length of crankshaft. The simplest solution, as used in most road car engines, is for each pair of cylinders to share a crank journal, however this reduces the size of the rod bearings and means that matching (ie. opposite) cylinders in the different banks are slightly offset along the crankshaft axis (which creates a rocking couple). Another solution is to use master-and-slave connecting rods, where the master rod also includes one or more ring pins. These ring pins are connected to the big ends of slave rods on other cylinders. A drawback of this is that the stroke of the slave rod is slightly shorter than the master, which increases vibration in a V engine.  One of the most complicated examples of master-and-slave connecting rods is the 24-cylinder Junkers Jumo 222 experimental airplane engine developed for World War II. This engine consisted of six banks of cylinders, each with four cylinders per bank. Each "layer" of six cylinders used one master connecting rod, with the other five cylinders using slave rods. Approximately 300 test engines were built, however the engine did not reach production.

Fork-and-blade rods.

Fork-and-blade rods, also known as "split big-end rods", have been used on V-twin motorcycle engines and V12 aircraft engines. For each pair of cylinders, a "fork" rod is split in two at the big end and the "blade" rod from the opposing cylinder is thinned to fit into this gap in the fork. This arrangement removes the rocking couple that is caused when cylinder pairs are offset along the crankshaft.  A common arrangement for the big-end bearing is for the fork rod to have a single wide bearing sleeve that spans the whole width of the rod, including the central gap. The blade rod then runs, not directly on the crankpin, but on the outside of this sleeve. This causes the two rods to oscillate back and forth (instead of rotating relative to each other), which reduces the forces on the bearing and the surface speed. However the bearing movement also becomes reciprocating rather than continuously rotating, which is a more difficult problem for lubrication.  Notable engines to use fork-and-blade rods include the Rolls-Royce Merlin V12 aircraft engine and various Harley Davidson V-twin motorcycle engines.

A connecting rod, also called a con rod, is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The connecting rod is required to transmit the compressive and tensile forces from the piston, and rotate at both ends.

Hammer mills.

These mills, which were original driven by water wheels, but later also by steam power, became increasingly common as tools became heavier over time and therefore more difficult to manufacture by hand.  The hammer mills smelted iron ore using charcoal in so-called bloomeries (Georgius Agricola 1556, "Rennherden", "Rennfeuer" or "Rennofen": from "Rinnen" = "rivulets" of slag or "Zrennherd" from "Zerrinnen" = "to melt away"). In these smelting ovens, which were equipped with bellows also driven by water power, the ore was melted into a glowing clump of soft, raw iron, fluid slag and charcoal remnants. The iron was not fluid as it would be in a modern blast furnace, but remained a doughy, porous lump mainly due to the presence of liquid slag. These lumps of sponge iron, known historically as "blooms" were initially compacted by hand using a sledgehammer. After that they were forged several times, usually with the trip hammer or with sledgehammers until all the slag and charcoal had been removed. For that, the iron was heated in another forge oven or smith's hearth. The iron could then be directly used as soft iron. A further improvement process, such as fining as used in blast furnace operations, was not needed.  The resulting coarse bar iron was then further worked externally e.g. in special, small hammer works ("Zainhammer") into thin iron rods, (e.g. thick wire), so-called rod iron ("Zaineisen"), which was needed by nailsmiths to produce nails.Further processing into so-called refined iron or into "elastic" steel for e.g. for sword blades, was carried out by specialised refined iron hammer forges or by blacksmiths on site.

Distribution.

Geographically, hammer mills were dependent on the availability of water power. At the same time, there had to be forests nearby to produce the large quantities of charcoal needed. In addition, there had to be deposits of iron ore in the vicinity in order to ensure that there was only a short distance to transport the iron-containing ores to the smelteries. Finally, agricultural land was needed in order to feed the many craftsmen involved.

Germany.

Hammer mills were widespread from the late Middle Ages in the following regions: In these regions there were iron ore deposits, which could be extracted with the means available at the time. There was a higher density in the Wupperviereck, where there were several hundred sites.  The Upper Palatinate was one of the European centres of iron smelting and its many hammer mills led to its nickname as the "Ruhrgebiet of the Middle Ages". Placenames with the suffix "-hammer" are very common in this region. The home of the lord in charge of a hammer mill was rather grandly known as a "hammer castle" or "hammer palace" ("Hammerschloss"). This usually inconspicuous "schloss", which acted as the family seat of the "hammer lord", was generally located in the immediate vicinity of the mill. Important hammer castles may be seen along the Bavarian Iron Route, for example in Theuern, Dietldorf and Schmidmühlen

Austria.

In Austria the hammer mills were mainly found in the Iron Roots ("Eisenwurzen") along the Austrian Iron Route around the tripoint of the states of Lower Austria, Styria and Upper Austria (e. g. Ybbsitz) and in the Upper Styrian valleys of the Mur and Mürz and their side valleys. The seats of the hammer lords ("black counts") were known as "Hammerherrenhäuser" ("hammer lord manors").

England.

Hammer mills were not widespread in England, but there are examples such as the one at Abinger Hammer in Surrey from which the village derived its name.

Products.

Typical produces of the hammer mills were:  These products were usually produced as semi-finished articles, but were sometimes also further forged into finished products such as sickles, scythes, shovels, weapons or miners' tools.

Well known hammer mills.

Most of the mills listed here have survived and are open to the public.  The Bavarian Iron Route ("Bayerische Eisenstraße") is an important holiday route in southern Germany that is rich in history. It runs for 120 kilometres, linking numerous historical industrial sites, which represent several centuries, with cultural and natural monuments. The Bavarian Iron Route runs along old transport routes from the Nuremberg Region near Pegnitz southwards to Regensburg and links the former iron centres of East Bavaria, namely the mining regions of Pegnitz, Auerbach, Edelsfeld, Sulzbach-Rosenberg and Amberg. From there it becomes a waterway, about 60 km long, on the rivers Vils and Naab until they empty into the Danube near Regensburg.

Culture.

In the literature, hammer mills were immortalised in Friedrich Schiller's ballad, "Der Gang nach dem Eisenhammer" (1797), which Bernhard Anselm Weber set to music for the actor, August Wilhelm Iffland, as a great orchestral melodrama, and later by Carl Loewe as a through-composed ballad.

A hammer mill, hammer forge or hammer works was a workshop in the pre-industrial era that was typically used to manufacture semi-finished, wrought iron products or, sometimes, finished agricultural or mining tools, or military weapons. The feature that gave its name to these workshops was the water-driven trip hammer, or set of hammers, used in the process. The shaft, or 'helve', of the hammer was pivoted in the middle and the hammer head was lifted by the action of cams set on a rotating camshaft that periodically depressed the end of the shaft. As it rose and fell, the head of the hammer described an arc. The face of the hammer was made of iron for durability.
