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 paper a methodology for accesing scientific data repositories on data grids is proposed. This methodology is based on ontology specification and knowledge representation. The concept of Knowledge Perspective is introduced, as the action of applying particular scientific conjectures…

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.

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…

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…

This paper describes the new features included in the Robolab 2 System, which permits the students to
work with a simulation of and industrial robot and carry out operations with the real robot through teleoperation.
Among these features, the flexibility…

This paper presents an object-oriented design and implementation of a software module to be used as the monitoring application for a Computer Integrated Building (CIB) in an intranet/extranet context., Sistemas Distribuidos - Redes Concurrencia - Sesión de pósters

In this research a system, referred to as Jubair-Khaireddin (JK), has been developed to assess the degree of similarity between two programs even though they look superficially dissimilar. The JK system has the capability to detect deliberate attempts of plagiarism.…

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…

This paper proposes a novel approach on embedding automatic parallelization in compilers. Due to an increasing popularity of multi-processor and multi-core architectures, software must take advantage of the processing power they offer and increase the level of parallelism as much…
