This thesis attempts to gauge the strengths and limitations of the Java programming language in terms of its use in the production of multimedia compositions: in particular, the ways in which Java supports the creation of interactive, non-deterministic musical works.…

Java provides many attractive features such as platform independence, execution safety, garbage collection and object orientation. These features facilitate application development but are expensive to support; applications written in Java are often much slower than their counterparts written in C…

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…

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…

Nondeterminism makes distributed concurrent systems difficult to test, monitor and control. An execution of a message-passing system is nondeterministic when message races exist. Message race occurs when, e.g., multiple conflicting requests from different clients are competing to be executed within…

Despite the popularity of Java, problems may arise from potential data-race conditionsduring execution of a Java program. Data-races are considered errors in concurrent pro-gramming languages and greatly complicate both programming and runtime optimizationefforts. A race-free version of Java is therefore…

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.…
