CHILDREN AIMED INTERFACES FOR ANDROID RUNNING DEVICES

The paper focuses on the development of mobile interfaces for children. The Android operating system is presented from appearance with its features, hardware support and its advantages over others operating systems. Mobile software development requirements on different platforms for mobile devices are identified and described. A graphical interface aiming children is designed and its features are presented. The interface includes an application for managing the school related tasks and time. Children manage the time of the days of the week differently. They have access to a task management system and a progress reporting tool. The advantages and development requirements are identified and discussed.mobile, software, development, Android, devices, interfaces, children

Contract-Based General-Purpose GPU Programming

Using GPUs as general-purpose processors has revolutionized parallel computing by offering, for a large and growing set of algorithms, massive data-parallelization on desktop machines. An obstacle to widespread adoption, however, is the difficulty of programming them and the low-level control of the hardware required to achieve good performance. This paper suggests a programming library, SafeGPU, that aims at striking a balance between programmer productivity and performance, by making GPU data-parallel operations accessible from within a classical object-oriented programming language. The solution is integrated with the design-by-contract approach, which increases confidence in functional program correctness by embedding executable program specifications into the program text. We show that our library leads to modular and maintainable code that is accessible to GPGPU non-experts, while providing performance that is comparable with hand-written CUDA code. Furthermore, runtime contract checking turns out to be feasible, as the contracts can be executed on the GPU

MAGDA: A Mobile Agent based Grid Architecture

Mobile agents mean both a technology and a programming paradigm. They allow for a flexible approach which can alleviate a number of issues present in distributed and Grid-based systems, by means of features such as migration, cloning, messaging and other provided mechanisms. In this paper we describe an architecture (MAGDA – Mobile Agent based Grid Architecture) we have designed and we are currently developing to support programming and execution of mobile agent based application upon Grid systems

Writer Identification Using Inexpensive Signal Processing Techniques

We propose to use novel and classical audio and text signal-processing and otherwise techniques for "inexpensive" fast writer identification tasks of scanned hand-written documents "visually". The "inexpensive" refers to the efficiency of the identification process in terms of CPU cycles while preserving decent accuracy for preliminary identification. This is a comparative study of multiple algorithm combinations in a pattern recognition pipeline implemented in Java around an open-source Modular Audio Recognition Framework (MARF) that can do a lot more beyond audio. We present our preliminary experimental findings in such an identification task. We simulate "visual" identification by "looking" at the hand-written document as a whole rather than trying to extract fine-grained features out of it prior classification.Comment: 9 pages; 1 figure; presented at CISSE'09 at http://conference.cisse2009.org/proceedings.aspx ; includes the the application source code; based on MARF described in arXiv:0905.123

Comparative Analysis of the CERN Accelerator Control Systems

In the framework of a future unique accelerator control structure for the LHC era, the convergence of the PS and SL systems was relaunched in 1997. The present study was triggered by a directive from the SL and PS Divisions to investigate and propose concrete actions. The two systems are compared in the areas of server architecture, networking capabilities including performance and flexibility, support for generic, re-configurable applications, and general purpose operator interfaces. Additional sub-systems covered by this report include the timing system software, error reporting, and the alarm sub-system. Areas where duplication of effort exists are noted, as are areas where each system could profit from the strengths of the other system. Additionally, areas are pointed out where features are missing from both systems as compared to other state- of-the-art accelerator control systems. A set of specific recommendations is proposed leading in the direction of future integration of these two systems. features are missing from both systems as compared to other state- of-the-art accelerator control systems.

Integration of Fault Localization into your GitHub Repository

Com a crescente complexidade e escala do software, existe uma forte necessidade de técnicas que auxiliem os desenvolvedores de software a localizar falhas com o mínimo de intervenção humana possível. O objetivo desta dissertação é analisar o uso de abordagens de localização de falhas baseadas em espectro para ajudar a descobrir falhas em programas Java, bem como o uso de bots no ciclo de vida do desenvolvimento de um software. As técnicas de localização de falhas baseadas em espectro foram escolhidas na área de pesquisa de localização de falhas de software devido aos seus baixos custos de execução e popularidade. Três ferramentas (GZoltar, FLACOCO e Jaguar) destacaram-se como as principais escolhas para a localização de falhas baseada em espectro em Java, de acordo com a pesquisa, e embora todas produzissem resultados comparáveis, o GZoltar foi preferido. Foi criada uma Action do GitHub que, quando integrada com o GZoltar, permite a análise de relatórios de localização de falhas baseada em espectro em qualquer repositório Java no GitHub. O resultado é um relatório detalhado das linhas de código potencialmente com falhas, personalizável pelo utilizador. Esta Action foi avaliada tanto em um repositório de exemplo como em vários projetos open-source. Embora a integração tenha sido bem sucedida no repositório de exemplo, as limitações do GZoltar impedem a sua integração na maioria dos projetos open-source, destacando a necessidade de atualizações e testes adicionais de compatibilidade.With the increased complexity and scale of software, there is a strong demand for techniques to guide software engineers to locate faults with less human intervention as possible. The purpose of this dissertation is to look into the usage of Spectrum-based Fault Localization approaches to help discover faults in Java programs, as well as the use of bots in the software development lifecycle. Spectrum-based Fault Localization techniques were found to be chosen in the research area of software fault localization due to their low execution costs and popularity. Three tools (GZoltar, FLACOCO, and Jaguar) stood out as the top choices for spectrum-based fault localization in Java according to the research, and even though all produced comparable outcomes, GZoltar was preferred. A GitHub Action was created that, when integrated with GZoltar, allows analysis of Spectrum-based Fault Localization reports in any Java repository on GitHub. The outcome of it is a detailed report of potentially faulty lines of code, customizable by the user. This action is tested in both a sample repository and several open-source projects. While successful integration is achieved with the sample repository, limitations of GZoltar hinder its integration with most open-source projects, highlighting the need for updates and further compatibility testing
