This paper describes the design and implementation of MATLAB*G, a parallel MATLAB on the ALiCE Grid. ALiCE (Adaptive and scaLable internet-based Computing Engine), developed at NUS, is a lightweight grid-computing middleware. Grid applications in ALiCE are written in Java and…

Region-based memory management offers several important advantages over garbage-collected heap, including real-time performance, better data locality and efficient use of limited memory. The concept of regions was first introduced for a call-by-value functional language by Tofte and Talpin, and has…

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…

In this note, I propose two extensions to the Java virtual machine (or VM) to allow dynamic languages such as Dylan, Scheme and Smalltalk to be efficiently implemented on the VM. These extensions do not affect the performance of pure…

Presentaciones del curso "Internet Programming with Java" impartido en la Université M'Hamed Bougara (Bourmerdes, Argelia) en abril de 2007., Proyecto financiado por la Unión Europea: TEMPUS JEP-32102-2004, Licence Professionnelle Technologies des Applications Web (Professional License for Web Application Technologies).

Mobile agent development is mainly supported by Java-based platforms. However, the weak mobility model they use, added to the inherent complexity of building location-aware software, impose strong limitations for developing mobile agents. In this article we present MoviLog, a platform…

Presentación del software libre JavaVis para prácticas de visión por ordenador.

This paper presents a laboratory session of an advanced programming course to introduce students to the technology involved with the Java programming language. In this special lab session the educational software tool VisualJVM is used, providing a graphical front-end to…

Java has adopted a mechanism to support parameterized types that will be available in the next major release. A draft specification to add generics to the JavaTM Programming Language was published two years ago [1] and a new version of…

Java 1.5 will include a type system (called JSR-14) that supports parametric polymorphism, or generic classes. This will bring many benefits to Java programmers, not least because current Java practise makes heavy use of logically-generic classes, including container classes. Translation…
