With the increasing adoption of Java for parallel and distributed computing, there is a strong motivation for enhancing the expressive elegance of the RMI paradigm with flexible and adaptable communication substrates. Java RMI is an especially powerful and semantically comprehensive framework

of context, we are focusing our efforts on the pieces of context that can be inferred automatically from sensors in a physical environment. We then present a conceptual framework that separates the acquisition and representation of context from the delivery and reaction to context by a contextaware

conceptual framework for understanding code mobility. The framework is centered around a classification that introduces three dimensions: technologies, design paradigms, and applications. The contribution of the paper is twofold. First, it provides a set of terms and concepts to understand and compare

RDF and RDF Schema are two W3C standards aimed at enriching the Web with machine-processable semantic data.

. With this paper, we present a native (C-based), flexible, adaptable, multi-protocol RMI/RPC communication framework that complements the Java-based RMIX variant previously developed by our partner team at Emory University. Our approach offers the same multi-protocol RMI/RPC services and advanced invocation

Recent years have witnessed the birth of a new paradigm for learning environments: animated pedagogical agents. These lifelike autonomous characters cohabit learning environments with students to create rich, face-to-face learning interactions. This opens up exciting new possibilities; for example

for network transfer, we make it harder to understand the behaviour of these programs at sourcecode level. To rectify this, this thesis gives a formal semantics for a distributed objectoriented language. We call this language DJ, and it models key features of the Java Remote Method Invocation framework

Framework (WSMF) that provides the appropriate conceptual model for developing and describing web services and their composition (complex web services). Spoken in a nutshell its philosophy is based on the following principle: maximal de-coupling complemented by scalable mediation service.

and optimization of XML query processors are the upcoming issues. Following a long tradition in database research, we provide a framework to assess the abilities of an XML database to cope with a broad range of different query types typically encountered in real-world scenarios.
