We show how to model service-oriented applications using process algebras such that, on the one hand, we can achieve a certain level of abstraction without being overwhelmed by the underlying implementation details and, on the other hand, we respect the concrete industrial standards used for implementing the service-oriented applications. By doing so, we will be able to not only reason about ap...

The need for creating content repository stores for e-learning systems grows as the number of available materials increases. Moreover, along with the number of courses, the problem of describing them in a unified form appears. While there are standards used for strict classification of elearning content, the store model still seems to be based on preservative relational databases approach. In t...

Object-Oriented Implementation of LTE Turbo Codes by Anusha Gangadi Master of Science in Electrical Engineering West Virginia University Matthew C. Valenti, Ph.D., Chair Turbo codes are a popular form of error correction codes as they perform close to the Shannon limit. Turbo codes have interesting features like parallel code concatenation, nonuniform interleaving, and an iterative decoding alg...

Life long, flexible, collaborative, and personalized learning are words that are being increasingly used, whenever education is discussed and designed. They express new and important demands on learning architectures, both with regard to pedagogy, organization and technology. Traditional learning architectures are based on teacher-centric and curriculum-oriented “knowledge-push”. In this paper ...

Anycast is a new IPv6 feature that supports service–oriented address assignments in IPv6 networks. However, because there are no protocol standards or even consensus on routing protocols, inter–segment anycast communications are not yet available. In this paper, we first discuss problems and solutions on inter–segment anycast communications. Based on our findings, we propose two routing protoco...

Today, source code occurs in diverse programming languages with documentation in miscellaneous standards, comments in individual styles, extracted metrics, or associated test cases that is hard to exploit through information retrieval or knowledge discovery techniques. Typically, the information about object-oriented source code for a software system is distributed over several different source...

The World Wide Web Consortium [W3C] has recently issued XML 1.0 as a Recommendation [XML]. XML, the Extensible Markup Language, is a data format for structured document interchange on the Web. In this paper, we put forward the position that XML, together with (future) standards based on XML, will play an important role in the development of open hypermedia systems. Many of objectives of the XML...

Web services have become a universal technology for integration of distributed and heterogeneous applications over the Internet. Many recent proposals such as the Business Process Modeling Language (BPML) and the Business Process Execution Language for Web Services (BPEL4WS) focus on combining existing web services into more sophisticated web services. However, these standards exhibit some limi...

For supporting process interconnection, on top of an existing open-source Business Process Management (BPM) environment oriented to Web Services (modeling module and execution engine, BPEL Business Process Execution Language compatible), this paper will propose a support to task-oriented, interactive decisional activities to be performed by CNO (Collaborative Networked Organizations) Actors. At...

eServices are the building blocks for loosely-coupled, distributed applications based on the Service Oriented Architecture (SOA) principles. One of the major benefits they offer is interoperability both between components of service oriented systems and between different systems. Still, the variety and diversity of implementations and interpretations of SOA and the vast amount of emerging stand...
