Manipulator movement speed down using for object : Weight estimation
Abstarct: Teach-Robot is simple 5 axles manipulator built on servo motors used for education purposes. Servo mot rs based on DC motor slow down due to the increased load. It is po sible to estimate object weight by measuring time int rval required to reach specific positions. The article presents the possibility of estimating weight of the object using effect of man ipulator speed slowdown under load increasing.
Modern Internet Based Production Technology
Recent a globalisation of technology and economics world causes that possibility for Internet applications are moved from off-line data processing to on-line data streaming. Internet is often becoming a part of real production processes that thanks to Internet can grow into more efficient and better distributed. A typical example of an implementation of modern production technologies using modern information and communication technologies (ICTs) can be a company with headquarters in one country but having chain of production sites all over the other countries. Internet in this case can be used not only for data transfer from e.g. economics, management, logistics and marketing, but also for data flow regarded to quality of production, failures and others. It enables to achieve recent information about technology used. Moreover, it allows interfering with production system, e.g. in case of need it is possible to actively interact into production system.
Mississippian Barnett Shale: Lithofacies and depositional setting of a deep-water shale-gas succession in the Fort Worth Basin, Texas
The Mississippian Barnett Formation of the Fort Worth Basin is a classic shale-gas system in which the rock is the source, reservoir, and seal. Barnett strata were deposited in a deeper water foreland basin that had poor circulation with the open ocean. For most of the basin's history, bottom waters were euxinic, preserving organic matter and, thus, creating a rich source rock, along with abundant framboidal pyrite. The Barnett interval comprises a variety of facies but is dominated by fine-grained (clay- to silt-size) particles. Three general lithofacies are recognized on the basis of mineralogy, fabric, biota, and texture: (1) laminated siliceous mudstone; (2) laminated argillaceous lime mudstone (marl); and (3) skeletal, argillaceous lime packstone. Each facies contains abundant pyrite and phosphate (apatite), which are especially common at hardgrounds. Carbonate concretions, a product of early diagenesis, are also common. The entire Barnett biota is composed of debris transported to the basin from the shelf or upper oxygenated slope by hemipelagic mud plumes, dilute turbidites, and debris flows. Biogenic sediment was also sourced from the shallower, better oxygenated water column. Barnett deposition is estimated to have occurred over a 25-m.y. period, and despite the variations in sublithofacies, sedimentation style remained remarkably similar throughout this span of time.
