There can be two vital criteria of selecting an algorithm to fulfil one’s encryption requirement. The security level of the cipher (secrecy) and the encryption time (performance). There is less focus on secrecy of ciphers as a security measurement, thus…

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…

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…

Programming embedded devices has been historically a difficult task, involving the learning of the features of a specific device such as the assembly language of a processor. This led to the use of Java in embedded system as a way…

This paper presents a free Java software platform which enables users to easily create advanced robotic applications together with image processing. This novel tool is composed of two layers: 1) Easy Java
Simulations (EJS), an open-source tool which provides support…

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 introduces a new set of compact interactive simulations developed for the constructive learning of computer networks concepts. These simulations, which compose a virtual laboratory implemented as portable Java applets, have been created by combining EJS (Easy Java Simulations)…

This report describes new excavations at the site of
Kendeng Lembu in East Java, a location previously
researched by van Heekeren and Soejono. The new
research in several locations has revealed a Neolithic
layer with red-slipped pottery, and a separate…
