Texte intégralRésumé :
This research is a study on the adaptation of a training program aimed to increase focused attention into a computer. It aims to develop a tool for such training by applying some adaptations into a computer program (software). This study uses concurrent mixed methods (using quantitative and qualitative research methods at the same time). In the first process, the software was assessed by a Game Developer expert and three child and adolescence clinical psychologists. The expert of Game Developer suggests a change of the intensity of the color of the stimulus and the screen background. Using the Content Validity index (CVI) technique, the psychologists found that the “Attention Focus Training” software has a value of S-CVI/Average (S-CVI/AVE) = .91 (> .80), indicating its conformity to the existing theories. The next stage is user experience by three child and adolescence clinical psychologists, conducted by comparing the use of the software and manual tools. It shows that the software is more practical and tends to have less negative bias.

Texte intégralRésumé :
When a successful software system is maintained and evolved for an extended period of time, original design documents become obsolete and design rationales become lost, so reverse engineering activities to reconstruct such information become critical for the software's continued viability.Pattern matching provides a solid framework for identifying higher level abstractions that may be instances of predefined plans (commonly used algorithms and cliches), programming concepts, or abstract data types and operations. This thesis discusses two types of pattern-matching techniques developed for plan recognition in Program Understanding.
The first type is based on Software Metrics and Dynamic Programming techniques that allow for statement-level comparison of feature vectors that characterize source code program statements. This type of pattern matching is used to identify similar code fragments, and code cloning, facilitating thus code modularization, code restructuring and efficient localization of the occurrence of similar programming errors.
The second type addresses the problem of establishing correspondences, between a parse tree of a custom abstract description language developed (ACL) and the parse tree of the code. Matching of abstract representations and source code representations involves alignment that is again performed using a Dynamic Programming algorithm that compares feature vectors of abstract descriptions, and source code. The use of a statistical formalism allows a score (a probability) to be assigned to every match that is attempted. Incomplete or imperfect matching is also possible leaving to the software engineer the final decision on the similar candidates proposed by the matcher.
The system has been implemented to analyze software systems written in PL/AS and C.

Texte intégralRésumé :
Program analysis is a process of estimating properties of a program statically. Program analyses have many applications, including compiler optimizations, software maintenance and testing, and program verification. In this dissertation we present a new framework for efficient program analysis. At the heart of our approach is a new program representation called the DJ Graph. Using DJ graphs we present several new algorithms for solving problems encountered in program analysis. The problems that we have solved range from a simple loop identification problem to sophisticated exhaustive and incremental data flow analysis, including the construction of Sparse Evaluation Graphs. The algorithms presented here are simple, more general, and/or more efficient than existing methods for solving similar problems. To study the effectiveness of our algorithms on real programs we implemented many of them, and experimented on a number of FORTRAN procedures taken from standard benchmark suites. Our results indicate that the algorithms presented here perform well in practice.

Texte intégralRésumé :
A fundamental problem in interprocedural program analyses is the need to represent and manipulate collections of large sets. Binary Decision Diagrams (BDDs) are a data structure widely used in model checking to compactly encode large state sets. In this dissertation, we develop new techniques and frameworks for applying BDDs to program analysis, and use our BDD-based analyses to gain new insight into factors influencing analysis precision.To make it feasible to express complicated, interrelated analyses using BDDs, we first present the design and implementation of JEDD, a Java language extension which adds relations implemented with BDDs as a datatype, and makes it possible to express BDD-based algorithms at a higher level than existing BDD libraries.
Using JEDD, we develop PADDLE, a framework of context-sensitive points-to and call graph analyses for Java, as well as client analyses that make use of their results. PADDLE supports several variations of context-sensitive analyses, including the use of call site strings and abstract receiver object strings as abstractions of context.
We use the PADDLE framework to perform an in-depth empirical study of the effect of context-sensitivity variations on the precision of interprocedural program analyses. The use of BDDs enables us to compare context-sensitive analyses on much larger, more realistic benchmarks than has been possible with traditional analysis implementations.
Finally, based on the call graph computed by PADDLE, we implement, using JEDD, a novel static analysis of the cflow construct in the aspect-oriented language AspectJ. Thanks to the JEDD high-level representation, the implementation of the analysis closely mirrors its specification.

Programming in a multiprocessing environment creates additional complexity issues above those encountered in a uniprocessing model. Animation of the underlying software data structures has been shown to help in management of such issues in uniprocessing environments. Animation tools for multiprocessing environments should also be of assistance to software engineers constructing parallel processing software systems. MPA is an environment that supports creation ofanimations that support multiprocessing applications in the Smalltalk programming environment.

Texte intégralRésumé :
Developers invest a large portion of their development time exploring program source code to find task-related code elements and to understand the context of their task. The task context is usually not recorded at the end of the task and is forgotten over time. Similarly, it is not possible to share the task context with other developers working on related tasks. Proposed solutions to automatically record the summary of the code investigation suffer from methodological limitations related to the techniques and the data sources used to generate the summary as well as the granularity at which it is generated. To overcome these limitations, we investigate the use of machine learning techniques, in particular decision tree learning, to predict automatically the task context from session navigation transcripts obtained from developers performing tasks on the source code. We conducted a user study to collect navigation transcripts from developers engaged in source code exploration tasks. We used the data from the user study to train and test decision tree classifiers. We compared the decision tree algorithm with two existing approaches, and found that it compares positively in most cases. Additionally, we developed an Eclipse plug-in that generates automatically a developer session summary using the decision tree classifier learned from the data collected during the user study. We provide qualitative analysis of the effectiveness of this plug-in.Les d\'eveloppeurs de logiciels investissent une grande partie de leur temps \`a explorer le code source pour trouver des \'el\'ements du code reli\'es \`a leurs t\^aches, et aussi pour mieux comprendre le contexte de leur t\^ache. Le contexte de leur t\^ache n'est g\'en\'eralement pas enregistr\'ee \`a la fin de leur s\'eance d'exploration de code et est oubli\'e au fil du temps. De m\^eme, il n'est pas possible de partager le contexte de leur t\^ache avec d'autres d\'eveloppeurs travaillant sur des t\^aches reli\'ees. Les solutions propos\'ees pour enregistrer automatiquement le r\'esum\'e de leur exploration du code souffrent de limitations m\'ethodologiques li\'ees aux techniques et aux sources de donn\'ees utilis\'ees pour g\'en\'erer le r\'esum\'e, ainsi qu'\`a la granularit\'e \`a laquelle il est g\'en\'er\'e.

Texte intégralRésumé :
In order to perform meaningful experiments in optimizing compilation and runtime system design, researchers usually rely on a suite of benchmark programs of interest to the optimization technique under consideration. Programs are described as numeric, memory-intensive, concurrent, or object-oriented, based on a qualitative appraisal, in some cases with little justification.In order to make these intuitive notions of program behaviour more concrete and subject to experimental validation, this thesis introduces a methodology to objectively quantify key aspects of program behaviour using dynamic metrics. A set of unambiguous, dynamic, robust and architecture-independent dynamic metrics is defined, and can be used to categorize programs according to their dynamic behaviour in five areas: size, data structures, memory use, polymorphism and concurrency. Each metric is also empirically validated.
A general-purpose, easily extensible dynamic analysis framework has been designed and implemented to gather empirical metric results. This framework consists of three major components. The profiling agent collects execution data from a Java virtual machine. The trace analyzer performs computations on this data, and the web interface presents the result of the analysis in a convenient and user-friendly way.
The utility of the approach as well as selected specific metrics is validated by examining metric data for a number of commonly used benchmarks. Case studies of program transformations and the consequent effects on metric data are also considered. Results show that the information that can be obtained from the metrics not only corresponds well with the intuitive notions of program behaviour, but can also reveal interesting behaviour that would have otherwise required lengthy investigations using more traditional techniques.

Texte intégralRésumé :
Global connectivity has opened up a new dimension in education, namely, the concept of delivering education via technology to students who may never see their classmates or their instructor face to face. The typical school with its traditional classrooms does not exist in this new scenario, and many of the professionals responsible for developing distributed learning courses are new to the task. This chapter will guide the reader through the process of planning and implementing a distributed learning program. The model for this chapter is the distributed learning program provided by the Department of Defense Education Activity to schools serving the family members of U.S. military personnel at home and abroad. The DoDEA Electronic School (DES) offers sixteen courses to over six hundred students at 56 high schools in fourteen countries, spanning twelve time zones. The program has been in existence for over twelve years, evolving from a two-teacher program to a worldwide school headed by an administrative staff and employing 23 instructors and four technical support staff members. Courses currently available through the DES include seven advanced placement courses (Calculus AB and BC, Physics B, German, United States History, and Computer Science A and AB); five computer programming courses (Pascal I and II, Q-BASIC, Visual BASIC, and C++); economics; health; humanities; and science research seminar. In addition to offering student courses, the DES is in the process of adding an extensive staff development component. With teachers and staff based worldwide, the system can save a significant amount of travel money by providing staff development opportunities that are accessible at the local site. The DoDEA Electronic School grew up with technology. During those first years, students used an acoustic coupler and a telephone to call a central computer in the United States, where they accessed a text based conferencing program to communicate with their classmates and instructors. Today’s DES instructors develop their courses in Lotus Notes, and students can use either the Lotus Notes client or a Web browser. Domino servers at each school send and receive information via the Internet, resulting in efficient transfer of data. In today’s environment, rich with technology but short on hours in the day, there is no time afforded for the luxury of “evolving.” Professionals tasked with developing distributed learning programs for their organizations are given a staff, a budget and a mandate— and certainly a challenge. The goal of this chapter is to help those professionals meet the challenge by examining the key elements of a successful distributed learning program.

Texte intégralRésumé :
Abstract It is truly remarkable that although electrocardiographic (ECG) changes were first recognized as markers for ischemia about 1918, here more than 80 years later we are still discovering that there is more to learn in this area. In the last few years numerous papers point out new ECG markers that have utility and I predict this trend will continue into the future. This chapter has been revised to present the more commonly used (conventional) electrocardiogram exchanges separately from the less commonly recognized changes (unconventional). Although computers are being used more to evaluate the ECG changes associated with exercise, it is still essential to carefully scrutinize the ECG visually, since computer measures are far from error-free. Also, technical writers of computer programs are always years behind the latest knowledge base. This chapter presents many ways of evaluating the exercise ECG that have not been incorporated into a computer program and may never be. Careful inspection of tracings from appropriate lead systems, using properly applied electrodes and recording systems with a good frequency response, can usually result in accurate evaluation of changes now known to be clinically significant. If you want to be an expert in the evaluation of exercise tests, you will find many concepts mentioned here that will set you apart from those who examine only the ST segment.

Texte intégralRésumé :
Abstract The paper describes a procedure for calculating costs concurrent with the design process. The different modules of the computer program “IKF” are described. The modules include those for cost calculation, comparison and forecast. Form features are used for cost determination by classifying each feature and storing it in the detailed production plan. The production processes then follow from the list of stored features. The cost program takes the individual geometric data, e.g., part length, from the CAD program. The latter contains data sets, that describe the feature’s dimensions. The production time for the form feature is then calculated. From the time expenditures and the machine rates the program calculates the production costs for the given feature. Prior to developing the computer program a manual procedure was designed and developed. Upon testing, the group not using IKF took 40–50% more time and designed products that were about 80% costlier than the group using the IKF system. This procedure was then used as the model for the cost modules in a feature-based CAD program. Test cases dealing with sheet-metal design are described which demonstrate and quantify the advantages of this system.

Texte intégralRésumé :
In Egypt, surveying the industrial sectors revealed that in the last few years the industrial process heat (IPH) consumed more than 60% of the annual industrial energy demand, of which about 50% is in the temperature range from 80 to 150°C. Among different renewable energy resources, it is found that solar thermal technologies, especially parabolic trough concentrators (PTC) are more convenient for the IPH applications. Thus, the present work deals with studying the main design and performance characteristics that enable the local manufacturing of a PTC for IPH applications in the range of 80 to 150°C in Egypt. It includes theoretical and experimental parts. The theoretical part was conducted using a specially developed computer program based on the energy balance equations of each component of PTC. The experimental part was carried out on a test rig designed and constructed using mainly local manufacturing capabilities. Effects of concentration ratio, radiation, inlet temperature and mass flow rate of the heat transfer fluid, glass envelope diameter and top thermal insulation on the theoretical and experimental performance of PTC are graphically reported. Finally, a brief discussion of the local manufacturing possibilities as well as some identified barriers that can hinder promotion of the technology in a very suitable and huge market like Egypt is presented in this paper.

Texte intégralRésumé :
In the training of specialists in Physical education and sports field, the utilization of Web-based tools represents a relatively recent methodological approach. In the context in which a part of the students attending the initial preparation program participate in performance sports training, but the specialists involved into an educational process don't have any more the opportunity to take part in presential continuing training sessions, we think that we should initiate a new methodological approach to the process of building-up specific competences. The present paper aims at checking the efficiency of a Web-based tool utilization to build up the planning competences of the future physical education teachers. In this context, in order to design and develop the training activity, we used the exeLearning software, a tool that facilitates the creation and administration of the specific contents, but also the construction of some knowledge self-assessment questionnaires. The learning object was used by 80 students in the final year of their psycho-pedagogic training program, participants in the Computer-Assisted Instruction course. Following the application utilization, students were asked to draw up a planning document and to express their opinion about the used tool efficiency. To this purpose, we created and administered an opinion questionnaire made up of 12 items grouped in 4 categories - attitude toward the utilization of such learning tools, benefits and difficulties related to the utilization of the created learning object, possible directions of application to different study disciplines (bachelor's level), effects on the learning efficiency. Answers were correlated to students' competence level resulted from their evaluation in the Computer-Assisted Instruction exam. The conclusions of this paper highlight the possibilities to use the Web-based tool in the training of the future specialists in Physical education and sports field and they are accompanied by a series of proposals the application of which would bring real benefits to students.

Texte intégralRésumé :
In USA there are approximately 100 operating light water reactors (LWR) consisting fleet of both pressurized water reactors (PWR) and boiling water reactors (BWR). Most of these reactors were built before 1970 and the design lives of most of these reactors are 40 years. It is expected that by 2030, even those reactors that have received 20 year life extension license from the US nuclear regulatory commission (NRC) will begin to reach the end of their licensed periods of operation. For economical reason it is be beneficial to extend the license beyond 60 to perhaps 80 years that would enable existing plants to continue providing safe, clean and economic electricity without significant green house gas emissions. However, environmental fatigue is one of the major aging related issues for these reactors, and may create hurdles in long term sustainability of these reactors. To address some of the environmental fatigue related issues, Argonne National Laboratory (ANL) with the sponsorship of Department of Energy’s Light Water Reactor Sustainability (LWRS) program trying to develop mechanistic approach for more accurate life estimation of LWR components. In this context ANL conducted many fatigue experiments under different test and environment conditions on 316 stainless steel (316SS) material that is or similar grade steels are widely used in US reactors. Contrary to the conventional S∼N curve based empirical fatigue life estimation approach, the aim of the present DOE sponsored work is to understand material ageing more mechanistically (e.g. time dependent hardening and softening) under different test and environmental conditions. Better mechanistic understanding will help to develop computer based advanced modeling tools to better extrapolate stress-strain evolution of reactor component under multi-axial stress states and hence to help predicting their fatigue life more accurately. In this paper (part-I) the fatigue experiments under different test and environment conditions and related stress-strain results for 316 SS are discussed. In another paper (part-II) the related evolutionary cyclic plasticity material modeling techniques and results are discussed.

ABSTRACTThis work presents a comparative analysis using the mAP metricof the YOLOv7 and SSD algorithms applied to the field of computervision. The comparison is performed through the detection of potholeson highways and roads. In works defended by other authors,both techniques are considered for applications in computer vision.In this study, both models achieved promising results in potholedetection; however, it is observed that the YOLOv7 model reachedan mAP metric of 80%, while the SSD model obtained an mAP of73%. Thus, the results indicate that YOLOv7 is more efficient andaccurate in pothole detection in this specific context.

ABSTRACTThe installation of transmission line surge arresters (TLSAs) hasbeen one of the main solutions found to improve the performanceof overhead transmission lines (OHTLs) against atmospheric discharges.Thus, this work proposes a methodology for the optimalplacement of TLSAs in OHTLs, which is based on the couplingbetween an algorithm inspired by GVNS (General Variable NeighborhoodSearch) and the ATP (Alternative Transient Program) software.The line performance calculation is made considering thetransfer effect of the lightning surge due to arresters operation.This transfer mechanism that can lead adjacent towers to flashoveris rarely mentioned in the literature. A study is performed consideringtwo transmission lines. At the end, in order to analyze theperformance of the proposed methodology, experiments are carriedout to optimize the positioning of TLSAs in the mentioned OHTLs.To validate the developed methodology, the results obtained arecompared with the results acquired through the coupling of a GA(Genetic Algorithm) with the ATP and with the results achievedthrough a classic method for the placement of TLSAs based on thetower-footing impedances. The results show that aspects such asthe lightning surge transfer effect and favoring the positioning ofTLSAs in the lowest phase(s) should be considered in future studiesfor the design of algorithms for optimal placement of arresters onOHTLs.

Texte intégralRésumé :
This paper presents Luthier, a Smalltalk-80 framework, designed to support the construction of visual tools for dynamic program analysis. Luthier integrates computational reflection techniques based on meta-objets with hypertext and direct-manipulation user interfaces techniques, especially designed to build dynamically adaptable visualization tools through composition of basic behaviours. The framework introduces two main contributions: a meta-object protocol based on the concept of meta-objet managers - which allow the construction of specialized mechanisms for meta-object association and activation - and the explicit support for abstraction scales for the dynamic (and continuos) reconfiguration of visualizations allowing different levels of abstraction. Through the combination of these mechanisms it is possible to build highly-complex structures independently of the implementation of specific visualizations. This allows a greater level of reusability of visualizations, which it is often the most limiting aspect of software visualization systems.

Texte intégralRésumé :
Natural materials are able to achieve a wide range and combination of properties through the arrangement of the material’s components. These biological materials are often more effective and better suited to their function than engineered materials, even with the use of a limited set of components. By mimicking a biological material’s component arrangement, or structure, man-made bioinspired materials can achieve improved properties as well. While considerable research has been conducted on biological materials, identifying the beneficial structural design principles can be time-intensive for a materials designer. Previously, a text mining algorithm and tool were developed to quickly extract passages describing property-specific structural design principles from a corpus of materials journals. Although the tool identified over 90% of the principles (recall), many irrelevant passages were returned as well with approximately 32% of the passages being useful (precision). This paper discusses approaches to refine the program in order to improve precision. The text classification techniques of machine learning classifiers, statistical features, and part-of-speech analyses, are evaluated for effectiveness in sorting passages into relevant and irrelevant classes. Manual identification of patterns in the returned passages is also employed to create a rule-based method, resulting in an updated algorithm. An evaluation comparing the revised algorithm to the previously developed algorithm is completed using a new set of journal articles. Although the revised algorithm’s recall was reduced to 80%, the precision increased to 45% and the number of returned passages was reduced by 22%, allowing a materials designer to more quickly identify potentially useful structures. The paper concludes with suggestions to improve the program’s usefulness and scope for future work.

Texte intégralRésumé :
The present work had studied and determined various levels of usability and interactivity in haptic interfaces for manipulating 3D applications. It was applied to a Heritage Cultural system composed by Train Station and Steam Locomotive. A physical model and a railroad model were built. The system was operated by high school students. The information gathering was performed by the deductive method, collecting data about preferences, needs, and requirements for developing a 3D virtual environment using 3DSMAX 2011 Trial (3D Modeled Software) and Unity 4.3 Trial (Simulation Software), capable to engage and transmit information relevant to geographical, social and cultural aspects of the central highlands. Subsequently connected to a real model controlled by electronic systems. The inquiry made from high school students shows that 56 % possess ability and willingness for interfaces manipulation. Also, it was found an 80% of criteria for usability acceptance, and interactivity of 84% towards the current applications on mobile devices. As the final evaluation of the application, it was shown that the intervention of haptic interfaces on threedimensional applications connected to tangible environments, increased 95% of the usability and 100% of interactivity. We conclude that combining virtual systems with real ones accelerates learning processes at the secondary education level. It improves retention of information and allows the user to actively participate in virtual environments, converting recreational applications into academic and research tools.
