O presente artigo tem por objetivo apresentar um ambiente para a execução de avaliações remotas em Ensino á Distância, dentro do conceito de sistemas multiagentes. O emprego da tecnologia de Orientação a Objetos e o uso de Java como suporte…

Understanding software structural complexity and evolution plays an important role in controlling the software development and maintenance process. Recent studies have shown that the theory behind complex networks, especially the theory of scale-free networks, can be a useful approach to…

JAVA is a general purpose concurrent class-based object-oriented programming language. This work presents an interactive program that interprets JAVA source programs directly. The cornerstone of its execution model is an execution graph, in which each node is constituted by three…

In this note, I propose two extensions to the Java virtual machine (or VM) to allow dynamic languages such as Dylan, Scheme and Smalltalk to be efficiently implemented on the VM. These extensions do not affect the performance of pure…

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

Este artigo propõe recursos para o escalonamento de objetos distribuídos. Para tanto, são definidos dois mecanismos tidos como centrais para tal: um primeiro que irá realizar a instanciação remota de objetos Java, e um segundo que terá a cargo a…

Protecting sensitive information has become an important facet of software development.
One aspect of software security relies on information flow control (IFC), a technique for discovering information leaks in software. Despite the large body of work on language-based IFC, there…

En este trabajo se presenta una técnica para verificar modularmente atomicidad de programas bytecode Java multi-thread. Los programas deben contar con una especificación referente a los bloqueos y al acceso a los recursos compartidos para realizar la verificación modular. Se…

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…

El framework de desarrollo JSF (JAVA Server Faces) es uno de los más popularmente usados en el desarrollo de aplicaciones Web. Este incorpora la novedad de permitir construir “componentes a medida” o “componentes customizadas”, aunque la implementación inadecuada desemboca en…
