This paper presents an evolution of a simulation environment where situations in which a DDB should maintain data integrity are modeled and implemented. These situations include failures taking place during transactions, and the focus is mainly on the utilization and…

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…

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…

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…

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 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…

The purpose of this study is to overview the gap between the theory and the existing condition towards Eco Industrial Park in the North Coast Region, East Java Province. We used gap analysis method.  The result shows that industrial area…
