Sarkisov Master of Science in Software Engineering This project explores the feasibility of effective and stable implementation of a paired client/web-based software package that is integrated among multiple mobile and stationary computing devices with such devices utilizing various operating systems. It takes an existing software application, adds collaborative web-server driven capabilities while exploring porting it to various platforms and operating systems using a single development approach. In pursuit of the goals outlined above a large reverse engineering effort has been undertaken to understand existing open source software, setup the necessary development environments, add additional development libraries to have the software compatible with Android OS 2.2, create all of the necessary design and requirement documentation from scratch to support software development, and reprogram existing code base while also adding new functionalities which in total amounted to an increase in the code base by about 75%. Proper documentation has been provided turning this project into a case study of software engineering processes within a realm of small open source projects. The creation of the necessary design and requirements documentation is discussed in detail and the project now provides elements of a case study of software engineering processes within a realm of small open source projects. Collaboration features added to existing open source software provide a practical implementation of real

    Praise for Intel Threading Building Blocks “The Age of Serial Computing is over. With the advent of multi-core processors, parallel- computing technology that was once relegated to universities and research labs is now emerging as mainstream. Intel Threading Building Blocks updates and greatly expands the ‘work-stealing’ technology pioneered by the MIT Cilk system of 15 years ago, providing a modern industrial-strength C++ library for concurrent programming. “Not only does this book offer an excellent introduction to the library, it furnishes novices and experts alike with a clear and accessible discussion of the complexities of concurrency.” — Charles E. Leiserson, MIT Computer Science and Artificial Intelligence Laboratory “We used to say make it right, then make it fast. We can’t do that anymore. TBB lets us design for correctness and speed up front for Maya. This book shows you how to extract the most benefit from using TBB in your code.” — Martin Watt, Senior Software Engineer, Autodesk “TBB promises to change how parallel programming is done in C++. This book will be extremely useful to any C++ programmer. With this book, James achieves two important goals: • Presents an excellent introduction to parallel programming, illustrating the most com- mon parallel programming patterns and the forces governing their use. • Documents the Threading Building Blocks C++ library—a library that provides generic algorithms for these patterns. “TBB incorporates many of the best ideas that researchers in object-oriented parallel computing developed in the last two decades.” — Marc Snir, Head of the Computer Science Department, University of Illinois at Urbana-Champaign “This book was my first introduction to Intel Threading Building Blocks.

  • Ad-Hoc Data Transfer for Android Devices
    Master Degree Project Ad-hoc Data Transfer for Android Devices Author: Emre Baykal Date: 2013-03-17 Subject: Ad-hoc Data Transfer for Android Devices Level: Master Course code: 5DV00E Abstract With the introduction of smart phones and mobile devices, the rate of technology usage has became widespread. It is very likely to see anyone using mobile device on the street, in the bus, at work, at school or even at home no matter if there is a fully functional computer nearby. Particularly, the usage of smart phones is not just limited to basic communication; they are being used as a technological gadget in our daily lives for years. We can easily reach such applications on different fields e.g. image processing, audio tuning, video editing, voice recognition. With the help of these smart applications we are able to interact with our environment much faster, and consequently make life easier; relatively for sure. Apart from mobile phone industry, sharing and staying connected to our envi- ronment has become very popular. A person who has a mobile phones with latest technology desires to communicate with friends, share feelings instantly, and of course meet new people who understand him well. In this context, technology came to the point where needs of modern human overlaps todays technology. This study aims to provide a basic application to users who has got those needs in terms of sharing and communicating, for maintaining easy and costless solution. This study currently offers prototype application to this problem using WiFi Direct technology, and intends to be pioneer of its field in consequence of existing small numbers of related applications in the market.

The project was funded by the German Federal Ministry of Education and Research (Bun- desministerium für Bildung und Forschung, BMBF) in the support program “Hochschulfor- schung als Beitrag zur Professionalisierung der Hochschullehre – Zukunftswerkstatt Hochschul- lehre” (“Higher Education Research as a Contribution to the Professionalization of Higher Education – Future Workshop Higher Education”).

However, they cannot be considered learner-centric because they do not allow individual solutions. In contrast, assessing open-ended tasks is considerably more complex. Intelligent tutoring systems (ITS) aim at giving individual feedback fully autonomously, but due to their high development cost, they are available only for few domains.

  • A Framework for Supporting Automatic Simulation Generation from Design
    UNIVERSITY OF NEWCASTLE UPON TYNE DEPARTMENT OF COMPUTING SCIENCE UN IVERS ITY OF NEWCASTLE A Framework for Supporting Automatic Simulation Generation from Design by Leonardus Budiman Arief Ph.D. Thesis July 2001 Abstract Building a new software system requires careful planning and investigation in order to avoid any problems in the later stages of the development. By using a universally accepted design notation such as the Unified Modeling Language (UML), ambiguities in the system specification can be eliminated or minimised. The aspect that frequently needs to be investigated before the implementation stage can be commenced concerns the proposed system’s performance. It is necessary to predict whether a particular design will meet the performance requirement - i.e. is it worth implementing the system - or not. One way to obtain this performance prediction is by using simulation programs to mimic the execution of the system. Unfortunately, it is often difficult to transform the design into a simulation program without some sound knowledge of simulation techniques. In addition, new simulation programs need to be built each time for different systems - which can be tedious, time consuming and error prone. The currently available UML tools do not provide any facilities for generating simulation programs automatically from UML specifications. This shortcoming is the main motivation for this research. The work involved here includes an investigation of which UML design notations can be used; the available simulation languages or environments for running the simulation; and more importantly, a framework that can capture the simulation information from UML design notation. Using this framework, we have built tools that enable an automatic transformation of a UML design notation into a simulation program.
