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)…

El CD doble <i>La Música del Centenario</i>, es una propuesta artística que compila interpretaciones musicales de los cinco elencos estables de la Dirección de Cultura de la UNLP. Se trata de dos discos compactos: uno incluye un variado repertorio interpretado…

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…

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…

Side-effect analysis gives information about the set of locations that a statement may read or modify. This analysis can provide information useful in a compiler for performing aggressive optimizations. The impact of the use of side-effect analysis in compiler optimizations…

A fundamental problem in interprocedural program analyses is the need to represent and manipulate collections of large sets. Binary Decision Diagrams (BDDs) are a data structure widely used in model checking to compactly encode large state sets. In this dissertation,…
