Este trabalho apresenta uma forma de transformar aplicações orientadas a objetos tolerantes a falhas de crash, podendo ser utilizado em um ambiente distribuído baseado em objetos que se comunicam entre si, a fim de executarem uma ação. Para garantir a…

Authentication techniques for a large-scale network are essential for the booming applications of e-commerce and e-business. In this thesis, authentication techniques for a larger-scale network are discussed. In-deep discussions on the independent path technique are presented. An authentication protocol based…

In the context of an object-oriented programming language such as Java, the ubiquitous use of instance fields and the presence of pointers (references to objects) make it difficult to understand a program's memory usage. Understanding memory usage is a key…

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…

Mobile agents are often described as a promising technology moving towards the vision of a widely distributed scalable electronic market. The deployment of electronic services, especially in the area of electronic commerce, raises essential questions closely related to security issues.…

Virtual method calls are a fundamental feature offered by Java, an object-oriented programming language. However, they are also a source of degradation of performance at run time and imprecision in interprocedural analyses. There are several well known, inexpensive analyses that…

The explosive growth of the wireless users requires efficient channel utilization. In this thesis, we present a new channel allocation strategy with waiting queue model instead of the block-and-clear model so that the quality of service in cellular network can…

As the number of applications of computers controlling safety-critical operations increases, the need to ensure the safety and reliability of the software that controls those computers increases proportionally. Ultimately, such software properties are the result of appropriate design and implementation.…
