Interaction and interest management in a scripting language.

Interaction management is concerned with the protocols that govern interactive activities among multiple users or agents in networked collaborative environments. Interest management is concerned with the relevance-based data filtering in networked collaborative environments. The main objective of the former is to structure interactive activities according to the requirements of the application concerned, while the main objective of the latter is to provide secured data transmission of a subset of information relevant to each recipient. The research in these two important aspects of networked software has largely been carried out in specific application domains such as online meetings, online groupware and online games. This thesis is concerned with the design and implementation of high-level language constructs for interaction and interest management. The work that has been undertaken includes: an abstract study of interactive activities and data transmission in networked collaborative environments through a large number of variations of the noughts and crosses game; the design of a set of language constructs for specifying a variety of interaction protocols; the design of a set of language constructs for specifying secured data sharing with relevance-based filtering; the implementation of these language constructs in the form of a major extension of a scripting language JACIE (Java-based Authoring Language for Collaborative Interactive Environments); the development of two demonstration applications, namely e-leaming on Simulation of Network Trouble Shooting and online Bridge, using the extended JACIE for demonstrating the technical feasibility and usefulness of the design. These high-level language constructs support a class of complicated software features in networked collaborative applications, such as turn management, interaction timing, group formation, dynamic protocol changes, distributed data sharing, access control, authentication and information filtering. They enable programmers to implement such features in an intuitive manner without involving low-level system programming directly, which would otherwise require the knowledge and skills of experienced network programmers

Parallel Implementations of Cellular Automata Algorithms on the AGILA High Performance Computing System

this paper we discuss some basic concepts of cellular automata. We also discussed the implementation of four basic CA algorithms on the AGILA High Performance Computing System, and 8-node Beowulf cluster located at the High Performance Computing and Networks Laboratory of the Ateneo de Manila Universit
