Ease of programming is the main merit of script languages. In distributedcomputing environment, programmers need to be aware of locations of resources and need to write additional codes for using remote resources in scripts. this makes scripts more complicated than those which use only local resources and cancels out the merit of script languages. In this paper we propose a virtual single computer model on which programmers needn't be aware of locations of resources. Programmers write scripts which use remote resources and scripts which use only local resources in the same way We developed a prototype system which executes such scripts. the system is implemented on the existing mobile agent system called D'Agent. We evaluated the system through an experiment and demonstrated its usefulness.

Currently public networks have an enormous number of computers capable of providing many services. Autonomous mobile agents are being used to access their information sources. these agents are modeled in the context of network simulation as mobile network processes. this paper demonstrates distributed mobile agents can be simulated effectively using C++ over CSIM. C++ over CSIM achieves the clarity and logic of agent based simulation for network services. Inheritance and specialization under object orientation allow the design and reuse of simulation objects. this combination facilitates rather straightforward simulation designs that are scalable, accurate, flexible and generalizable. the design for such large scale simulation is sketched and the run time behavior of the simulator is analyzed.

Tailoring large ontologies can be a very cumbersome task. the Grid enables resource sharing to handle such tasks over a distributed environment. It makes sense then, to investigate the possibility of using resources on the Grid to tailor large Ontologies. this paper proposes a distributed ontology framework for tailoring ontologies in the Grid. the framework consists of five main categories;Ontology Processing, Ontology Location, Ontology Connection, Users' Connection and Algorithm Location.

this work describes authors' approach at the authors' university during last three years for the computer science second grade undergraduate students to experience parallel and distributedcomputing. the goal is set to give a solid understanding of parallel and distributed processing technologies and to build up basic skills in the field, such as parallel algorithms, multithread/network programming, IP/socket communication, MVC paradigm, RPC/Remote Method Invocation (RMI), Database/SQL, and JAVA/JDBC. the course features a combination of active experimental Learning and N to N networking approach. Unlike typical laboratories where central parallel servers or parallel machines are used (N users to one system networking), our laboratories do without them and instead organize groups of student PCs to form virtual parallel/distributed systems (N users to N systems networking). All PCs work as Servers as well as Clients. parallel Buckets Sorting and Virtual Shopping Mall implementations are employed for the course projects. the course consists of 14 ninety-minutes sessions within a semester, including introductory JAVA network programming and two projects. As the time is limited, the homework and pre-laboratory experiments are encouraged. the Web based course material distribution and the virtual laboratory environment contributed to bring most students to success.

this paper describes a replication algorithm for distributed real-time object-oriented databases in a static environment. All data requirements are specified a priori, and the algorithm creates replication transactions that copy remote data to a local site in order to guarantee that every data request reads temporally valid data. the algorithm conditions are proven to be necessary and sufficient for providing this guarantee. Test results indicate that under most conditions, this replication strategy is better than total replication, which is a typical strategy used in distributed databases.
