I propose a technique that identifies program properties that may indicate errors. The technique generates machine learning models of run-time program properties known to expose faults, and applies these models to program properties of user-written code to classify and rank…

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…

Acantholybas steinbaueri, a brachypterous new species, is described and illustrated from Java (Bali Island and Dammerman). The genus Acantholybas is redescribed, and a key to the four known species is provided.

This paper presents a JAVA based framework for RTL modeling and simulation of digital hardware designs. After linking between object-oriented concepts and RTL models, the JAVA analogy to features found in a widely used hardware description language like Verilog is…

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…

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…

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…

Nodes for emerging, high-density wireless networks will face the dual challenges of continuous, multi-year operation under diverse and challenging operating conditions. The wireless communication subsystem, a substantial consumer of energy, must therefore be designed with unprecedented energy efficiency. To meet…

DLP is a basic java-based IDE specifically conceived for DeLP, that allows to compile DeLP programs and queries into JAM opcodes, execute those opcodes, and even witness the actual step by step construction of the dialectical tree that is built…

The essential purpose of this paper is to describe a framework, in a simple and complete way, which enables the concurrent visualization of audio/video streaming combined with its corresponding synchronous vectorial information. The architecture presented uses Java JMF API, which…
