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 thesis discusses the design and implementation of a database programming language that supports the relational algebra for nested relations with arbitrary but finite levels of nesting, and the domain algebra for nested attributes at any level of the nested…

This Thesis deals with the cultural encounter between Islam and Javanese culture as represented by the slametan ritual. The major purposes of this thesis are threefold; (1) to give a brief account of the historical backdrop of the encounter between…

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…

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…

This thesis documents the design and implementation of computations, the procedural abstraction facility of a database programming language. Conceived as a special form of relation, computations fit neatly into the relational model. A computation is defined over a set of…

This thesis discusses the design and implementation of a relational database programming language, focusing on the domain algebra for nested relations. While the relational algebra provides operations to manipulate relations as data primitives, the domain algebra allows the manipulation of…

In this thesis I examine the issues of sex education in Western and Javanese society using a conceptual-comparative approach. My main goal is to highlight the importance of sex education for young people in Javanese society. Research foci and discoveries…
