the third bug, Configuration-272, concerns incorrectly escaping the , character; the class StringEscapeUtils still exhibits this problem.


Put di.erently, the semantic action of the previous production is a program transformation directly expressed in the parser: a substitution of an abstract syntax subtree pattern (its leaves being replaced by labels called metavariables), by another subtree pattern, as depicted on Figure 2.

other alternatives to our proposal include functional languages such as Haskell or Caml, featuring matching capabilities that considerably simplify the implementation of rewrite rules (the Visitor pattern is made worthless);  language extensions such as Prop [9] or Tom [2], augmenting one or several general-purpose languages with pattern matching and abstract (not concrete) syntax rewrite rules;  AST classes and traversal generation tools, like Treecc [16], which takes a similar approach to ours.


The desktop approach makes it possible to generate prototypes rapidly, and to test them more economically.

Commercial transactions executed over the Internet do not, with only a few exceptions permit the actual exchange there and then of the goods in question.1 Accordingly, what is exchanged electronically are normally commitments of this sort, i.e., promises of future action by one or more persons involved in the transaction.

the protocol supports a notion of e-commerce commitments as performatives, complementing Singh s model of multi-agent commitments.


That would depend on the goals, but in all cases the students from the constructivist class (class C) performed better in successor courses, on the average, than did the students from the behaviorist class (class B).

Otherwise, the garbage collector will get into a very lowthroughput regime where only major GCs are occurring.

for the case when the total heap size is .xed and the Eden size has to be traded off against the size of Old, the derived shapes of key GC functions (such as minor GC time and the amount of data promoted into Old at each minor GC as a function of the Eden size) were used to conclude in Section 6 that the optimal Eden size is expected to be greater than half of the free heap space (heap size minus the amount of data surviving the major GC).

The popularity of these robotic middleware systems has resulted in sizable libraries of components that are now available to roboticists.

we validated our approach by porting some of our existing JAUS components to ROS, and then executing those components on ROS using the ROS2JAUS bridge, and comparing the results of the hardware-inthe-loop system behaviors.


We therefore decided to replace the log4j component with the util.logging package from JDK 1.4.

the value of the AOP version in this case is that only the logger-aspect was changed.


In a software system with cloning, a single conceptual change (e. g., a bug .x) can thus potentially require modi.cation in multiple places, if the a.ected source code (or model) parts have been cloned.

then we cover the more thoroughly studied problem of clone detection in source code, to understand which of the methods proposed in this .eld could be applied to arbitrary models.

Splits already performed could of course be cached with the communicator, making the rooted calls at least partly persistent.

apart from bloating the MPI standard, this has a very serious drawback.


Since the Naive Algorithm does not take advantage of channel bu.ers, it always sends more dummy messages than the other two algorithms.

our experience porting C programs and building new applications for resource-constrained systems con.rms that experts can use these features to improve memory footprint and sometimes to improve throughput when used instead of, or in combination with, conservative garbage collection.


Nevertheless, in both cases, the system needs bounded time to reorganize its indexing mechanism and achieve high performance.

a node has to cooperate with other peers that store a value of a level i < pivotlevel in order to decide if this level is more appropriate.

In these conditions it is thus challenging to provide an abstract way of expressing parallelism that would still be compatible with current and possibly future architectures.

as their use is based on compiler directives which limit the separation of concerns, this solution can appear as less attractive for new developments.


Finally, we will brie.y discuss alternative encodings for the visitor pattern.

this .exibility comes at a price: extending the DSL with new operations, or even composing it with other languages, requires adaptation of both the data structure and the tree traversals.

Traditional solutions based on event systems and the Observer pattern have a number of inconveniences, but programmers bear them in return for the bene.ts of OO design.

unfortunately, modularization of update code is hard to achieve in the OO style, because dependencies must be imperatively updated every time an input value is changed which can occur in several places of the application.


Hence, they do not provide suitable abstraction mechanisms for large software landscapes.

as far as we know, those visualizations are limited to visualizing nodes and applications.


Similarly, blockIdx.x is the identi.er of the block to which a thread is assigned on the x-axis of block indices.

in addition, this solution would require more syntactic intra-block synchronizations, which should be carefully generated, as discussed in the background Section 3.


The application to both is possible since ~ in simulation and synthesis perform a similar function: adapting the module to the external world by protocol conversion or by u'ans- forming channel accesses from (an) abstraction level(s) to (an)other abstraction level(s).

In summary, the steps to identify free memory pages in a Linux-based guest VM are (1) Searches the header of Linux guest real-mode kernel image for the magic string HdrS , then extracts the kernel version information, and uses the kernel version information to either retrieve the corresponding free page check program if it exists, or dynamically composes the corresponding free page check program based on the kernel version s source code and con.guration .le, (2) Extracts from the System.map .le associated with the guest kernel s version the location of the memory map, and (3) Traverses every page descriptor in the memory map by calling the free page check program to determine if each traversed page is a Buddy page.

this work did not address the issue of how to programmatically extract the free memory map information from different versions and con.gurations of Linux kernels.

the only system calls that DoublePlay actually executes are ones that modify the process address space, such as mmap and clone.


While plenty of data distribution scenarios can still be found in the real world, existing solutions mainly come from DBMS providers.

usually, this information consists of user data input and the identifiers (ID) of the various business entities needed to fulfill the request.


The third mode is quite similar to the first mode but less straightforward.

RAFTING focuses on the resources used by features, rather than the features themselves.

intuitively if a given feature has goals that cannot be achieved given the USES and PRODUCES relationships and resources speci.ed for the system, then a feature interaction is detected.


It was decided to structure the metamodel in this way since it better represents the SPL project we are developing in the mentioned private company.

These four questions align with the traditional life cycle considerations of requirements, user interface, high-level design, and low-level design, but cast as design, we now know that there are some similarities to be expected in how they are explored, some unique aspects and challenges, but most of all a very strong relationship.

parnas [88] first defined expected benefits of modularization and proposed what is still the most ubiquitously applied criterion to date: achieve information hiding.


Levels 2 to 4 illustrate the importance of being aware of the user needs throughout the design process.

there is an upper bound on speedup, which is reached when the network becomes saturated.


3.6.1 Awkward Cardinalities As already explained in Section 2.2, DTDs offer a restricted mechanism to specify cardinalities, i.e., there are no language concepts for defining cardinalities having a lower bound greater than one and for defining cardinalities having an upper bound other than 1 or * .

with intra-layer mappings, one is able to derive intralayer mappings at lower layers of the architecture.


Since we are using dynamic information instead of a static analysis, our results give an upper bound on what could be achieved via a static compiler-based approach.

the opportunities for inlining are highly dependent on the individual benchmark, and for many benchmarks are quite limited.

our critical values are specific to the RHEL4 kernel during the time period we studied, so other projects may have different exact critical values.


Rather than imposing a schedule, our approach uses the databases own concurrency manager to avoid introducing arti.cial dependencies, thus permitting higher concurrency.

since the complexity and amount of code in the shepherd is orders of magnitude smaller than in the replicas, we believe that assuming non-Byzantine behavior is reasonable.

On the other hand, the limited battery power of the sensor S o u c a i s ( )  r e R d u R nodes imply that the amount of redundancy needs to be restricted to conserve the lifetime of the sensor nodes.

this is because, when source performs network coding, each outgoing packet from the source contains information of all packets in the same generation.


The analysis of these randomized distributed protocols is already far from trivial, and it is seems di.cult to go beyond these simplistic interference models.

periments, we .nd that if p =1/2, .xing tv at a lower level, i.e., tv = 4, gives the best throughput, since in this case p is much higher, and hence there are more collisions and busy time periods.


5.3 Software Architecture There are many different books and seminars on software architecture, but none of them really addresses all relevant issues.

once the architect is accepted into the qualification program, they enter a 9-month program which consists of a mix of workshops and time to work on their normal projects.


The goal is to specify both the architecture and performance of a large component-based distributed system in terms of new components, as well as predefined components and inter-component communication patterns that are stored in a reuse library.

But to accept functions for logical reasoning, users often need to help ACL2 prove termination.

since the completed line is never beyond the todo line, these induce three (potentially empty) regions in this order: the completed region, which contains everything that has been accepted by the theorem prover; the todo region, which has everything currently being or scheduled to be processed; and the working region, which is for editing at will.

What remains is its dependency on other components.

the decomposition process is an art form; the architect must decide whether to assign a specific functionality to a given component or to defer some or all of the functionality to other components, with a goal of minimizing complexity.


After deleting all temporary .les, the average random write speed equals to that of an over-provisioned SSD, where the additional spare capacity is not used by the operating system.

The failure occurred because the InterComm con.gure process reported a problem in linking to Fortran libraries from C code.

third, we will investigate adding cost models into plan execution strategies to prioritize the order in which tasks are distributed so as to maximize the number of direct dependencies for the SUT tested within a .xed time period.


In the JAM/HiPE run-time system the ERLANG processes are represented using ordinary C-language data structures.

makes the ratio between the number of cameras and number of sensors about 0.1.


Consequently, many memory requests are simultaneously sent to the data-side memory in the VLIW mode.

the D-Cache size (x) is the smallest size at which its miss rate becomes less than 0.3% for each application.


To answer this question, developers often attempt to understand how the code works now to determine how it would work differently after the change.

we are currently designing a tool to make this easier.

in other words does it mean that even with OSSS full control of synthesis results in case of design functionality stays in the hands of designers.


This proves to be insuf.cient in practice because the generated method can be fairly long (all code versions are concatenated).

current approaches to aspect weaving fail to support this vision because of the computational interference effect: the mere presence of an aspect perturbates the observations made by other aspects, because of the extra join points that are produced and observable by all aspects.


Often, the memory complexity is much higher on both n and m (e.g., [21] uses 160n bytes for general surface simpli.cation), and generating approximations of large datasets is usually quite hard.

there are several issues in implementing external memory algorithms, and these issues can greatly affect the overall performance of a system.


In the case of the collaboration application described in this paper, the autonomic goal is to manage the audio/video latency provided by the servers by adding more servers to the cloud s pool of active servers whenever servers get overloaded.

the self-organizing control is achieved in four control decisions: 1.


For the planner, the subtasks decomposition is totally ordered, for example, destroySingle is called before removeBindingFrom.

one exception to this precondition set must be highlighted.

in ClientVisor, by setting the parameter of the scheduler in VMM (e.g., weight and cap of credit scheduler), the COS is ensured to share at least 95% of the CPU cycles.


Our approach is derived from the results of a previous analysis of how XP deals with the security activities and requirements stated in the Systems Security Engineering Capability Maturity Model and the Common Criteria [9, 31].

iteration planning involves revisiting the release plan, adding new requirements, selecting relevant requirements and refining requirements.


These primitives, rather similar to those of other mobile agent frameworks, do not require direct use of the name of the method to be invoked, but an action name has to be specified: by us-ing the se~action primitive, the callee agent can establish the correspondence between an action name and the rel- ative agent method.

get and peek allow the programmer to specify a matching expression based on Unix- style regular expressions.


The remainder of this paper is organized as follows.

with aggressive releasing, the paging daemon does not need to .nd pages to reclaim, thus greatly reducing the number of invalidations.


Figure 3 shows the performance bene.t from using DIO with the workloads comprised of HPCC, HEP SPEC and NAS benchmarks on AMD machine with 8 cores.

as can be seen, the slowdown varies greatly from job to job, but it can be as high as 778% for some MPI applications.


This adaptive mechanism is altered in this study, in order to be implemented in a system where computing nodes impose energy constraints.

we consider that this constraint is imposed by the cooling policy applied to the computing node.


The Colorado State University literature does not consider that the NVD data points they use may not be independent.

here, I use benign to indicate an actor that follows a responsible disclosure policy: vendors are informed about a vulnerability and given time to create a patch before the detector makes the vulnerability public.


The application instantiates the VM using a web-service call while identifying itself as user B by supplying the appropriate credentials.

so the user interface of cloud operators would have to be changed to make the envisioned system work.


The server returns a pointer to the ses sion object.

EpiChord uses parallel requests [25] to avoid sending redundant queries.

the only parameter we varied here was the amount of lookup traffic per node.


Examination of the resulting external service times revealed that they were taking significantly longer than expected (10s of minutes), and that the maximum SLA would be exceeded.

it was evident that the eight new samples were obtained from a newer configuration of the upgraded system compared with the previous samples, so we were unable to use the previous two clean samples in conjunction with the new ones.


This kind of method is vulnerable to every cryptanalysis attack described in the last section.

the first byte is the opcode of the new extended instruction, and the following byte is identifies the original bytecode.


This process continues until the two resulting models are similar.

to compute the execution cost associated with a path for a (possibly di.erent) target architecture, we translate the instructions present in the basic blocks of the (SPARC) application binary into instances of generic RISC instruction classes.


Furthermore it requires compatibility in a semantics level to abide by standard interfaces or agreed rules, so the adaptor takes care of underlying tasks that can t be done with syntactic translation.

to achieve this goal, it translates APIs and messages into the form that can be processed by underlying native modules to control the virtual resources and networks.


However, it requires human expertise on the targeted device or system, which may include proprietary con.gurations and use of algorithms and optimizations that are not disclosed.

to ensure that all data were accessed from disk the system bu.er caches of the compute nodes and data servers were .ushed prior to each test run.


This dimension of protocol analysis and veri.cation commitment and trust greatly enhances the utility and expressiveness of strands.

If offset is set to dim1, streamMerge becomes streamCat.

we use opt to denote the version generated from our compiler.


It is important that tools support Class 3 Web sites in the future: since Web sites are interactive in nature, their operational profile may not be accurately reflected by examining only HTML document structure.

with UltraDev you can import an existing Web site but only one from a local network disk or an FTP site to which you have access.


BlueJ, a software tool for teaching OO principles, has been designed so that polymorphic behavior may be illustrated easily: Interactively invoking the same method on different objects can exhibit different behavior, and objects of distinct (sub-)classes may be passed to a method expecting the superclass as a parameter.

can this be avoided, or if not, leveraged?

Separate lists of arguments are interleaved between the parts of the name, allowing them to be clearly labelled with their purpose.

our problem, then is how to support pattern matching in a pure object-oriented language, with minimal extensions.


While running the programs, each time a loop stops, we collect the actual trip count and compare it with the estimated trip count.

we compare our approach against Minas, a middleware that supports NUMA-aware data allocation, and show that we can outperform it by up to 50% in some cases.


the exploration along this path terminates with a true result, as two con.gurations are visited with the same local states s2t1r0u2 and with identical obligations (last con.guration in the highlighted path shown in the partial view).


A consequence of the variation in implicit assumptions embedded in the different models is that it is not easy to compare models or transfer knowledge derived from one model to another.Thisisproblematicfor thefollowing reason.Thereisgeneral agreementinthe softwareindustrythat software project outcomes can be maximised by tailoring the process to the speci.cs of individual projects.

For our example, the necessary mapping between parameters of the events in Table 1 is informally described in Table 2.

cONCLUSIONS AND FUTURE WORK Even though development based on multiple frameworks has been widely adopted, the guarantee of behavioural preservation concerning their composition is still a research challenge.


From the perspective of design evolution, one single anonymous class does not have too many effects on software design, since, according to the Java specification, anonymous classes are mainly used to avoid creating a bunch of simple subclasses or implementations of interfaces.

there has been some work at investigating the use of comparative analysis of different snapshots of a software system for drawing inferences regarding its evolution.


4.3 Class Initialization Class initialization occurs in Java when a class is .rst used, and involves invoking a special static method in the class bytecode called an initializer.

more advanced forms of execution capture, such as omniscient debugging [17], present the state of a process at a single point in time using a similar re.ective model equally incompatible with evaluating expressions.


The possibility of gathering information related to orientation change by logging user activity seemed to be promising.

unnecessary slowdowns in the application development should be avoided.

Since the mapping had already been the knowledge of the participant, formally specifying the mapping did not need much thinking, not only because it was a process of writing down what was known by the participant, but also the TDL was easy to use to express the mappings.

we focus on automated use case derivation, i.e.


We present LVars, a new model for deterministicby-construction parallel programming that generalizes existing single-assignment models to allow multiple assignments that are monotonically increasing with respect to a user-speci.ed lattice.

Hostile environment testing must thus be a part of any overall testing strategy.

if the application is placed under stress or not, any communication with the file system, the registry, the network, an output device or any component external to the software must be scrutinized for security-related side effects.

the ability for every node to be certain of which operations other nodes can carry out is essential.


This pattern of message exchange authenticates B using its X.509 public key, and provides secrecy and correlation between request and response.

there may be other compromised users, identity providers, and relying parties, but we assume that A does not have any interaction with them.


Different theories exhibit both general and subtle differences, for example a difference in the type or number of sub-processes in the process model, or a difference in the way knowledge is represented.

due to the large number of ID theories and the diversity of elements which they are composed of, the first stage of any systematic appraisal would be to develop a framework for classifying and analyzing ID theories.


If the marketplace and technology disruption (as introduced by Clayton Christensen) are the key drivers then the legacy will likely fade away and no one will notice that it s gone aside from design and support staff looking for new opportunities and a few trailing edge customers.

object-oriented design tools and programming language can still be applied in ways that produce spaghetti code.


Similar to the effect of changing the compute time is changing the variability across job times.

an oblivious scheduler which did not use our planning techniques but did observe capacity constraints might allow many pipelines to initially execute while the batch data is small.

After a job is scheduled, its bandwidth requirement is subtracted from BWremain.

in our study, we assume a round-robin policy is used for our estimation.


In our current prototype, the only type of argument supported is String, so the arguments must be in quotes.

In the remaining of this section, we still designate this program as the C program , to distinguish it from the O CAML program proposed in this paper.

side-effects are purely local and not exposed to the client code, and the usual bene.ts of functional programming remain (immutable data structures for lists, pattern-matching, polymorphism).


An Internetware component is ultimately an independent service unit that satisfies required functionality and quality.

the general process for the Delphi technique includes several steps: a) a group of experts give their evaluation independently; b) evaluations are collected and sent out to experts; c) experts refer to other evaluation and reevaluate; d) repeat step b) and c) when experts stop changing their attitude.


On server side, mapping from user certi.cate to login name is provided by standard Globus grid-map.le.
