Java decompilers convert Java class files to Java source. Common Java decompilers are javac-specific decompilers since they target bytecode produced from a particular javac compiler. We present work carried out on Dava, a tool-independent decompiler that decompiles bytecode produced from…

The knowledge imperfections should be considered when modeling complex problems. A solution is to develop a model that reduces the complexity and another option is to represent the imperfections: uncertainty, vagueness and incompleteness in the knowledge base. This paper proposes…

With the emergence and evolution of computer hardware, software and networks - virtual classrooms now exist which enable teachers and students to experience learning activities and to work together at a distance either directly or on a part-time basis. We…

La plataforma .NET de Microsoft, así como los entornos de programación en JAVA, se basan en una filosofía de just-in-time compilation (compilación bajo demanda al momento de la ejecución). Los programas desarrollados de esta manera se ejecutan en un entorno…

In this article we present a performance comparison of four symmetric block ciphers namely DES, Triple-DES, AES, and Blowfish. Performance evaluation based on CPU execution time is conducted under WinXP and Ubuntu /Linux version 8.10 operating system platforms. The study…

The paper describes a framework for the implementation of an elearning system based on the Semantic Web, using software agents and Java Web Services. Hopefully we have elucidated the enormous potential of making web content machine-understandable. One of the killer…

O objetuvo deste comunicado é apresentar a implementação Java da transformada discreta de Fourier e sua inversa, usando a biblioteca Java Advanced Imaging (JAI), para mapeamento entre os domínios espacial e de frequência em imagens digitais., 2006, Acesso em: 28…

It is a common practice to retrieve code from an outside source, execute it and return the result to the user. During execution secure data can enter the program by user input or access of a data resource. It is…

Varios intentos se han realizado para mejorar la producción de programas en diversos lenguajes. No es difícil imaginar cuán conveniente sería poder aplicar técnicas inteligentes para colaborar en este sentido. El presente trabajo realiza el desarrollo y evaluación de un…
