This paper presents a new approach to algorithm design and analysis that benefits from the OO characteristics of Java. It consists of first defining the inheritance structure of a collection of algorithms, at different levels of abstraction. Then, correctness proofs…

This thesis describes a framework for collecting, analyzing, and visualizing dynamic data, particularly data gathered through Web questionnaires. The framework addresses challenges such as promoting user participation, handling missing or invalid data, and streamlining the data interpretation process. Tools in…

El presente trabajo investiga las herramientas que provee el lenguaje Java para el desarrollo de aplicaciones de ingeniería que transmitan los datos a través del internet o para modificar aplicaciones existentes para proveerles esta funcionalidad. Para ello, primeramente se presenta…

Java programs are deployed in a bytecode format that is executed by a Java virtual machine (JVM). JVM performance is determined by several major components: execution engine, garbage collector, and threading system. The static compilation and optimization approach, such as…

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.

In designing compiler analyses and optimisations, the choice of intermediate representation (IR) is a crucial one. Static Single Assignment (SSA) form in particular is an IR with interesting properties, enabling certain analyses and optimisations to be more easily implemented while…
