the main rock mass classification systems make use of similar rock mass parameters. due to lack of comprehensive estimation systems, determining the real specifications of jointed rocks faces some difficulties. a vast number of parameters with various degrees of impact are involved in such definitions. combination impact of all the effective parameters is to be figured out in order to come up w...

Java RMI provides an elegant and powerful model for invoking member functions on objects that exist in remote address spaces. Unfortunately, it is a Java-to-Java communication model, and in many of the scienti c applications we would like Java objects to interact with modules written in C++ or Fortran. This paper explores the design of RMI and extracts a subset of the RMI object model that is c...

Java offers interesting opportunities for parallel computing. In particular, Java Remote Method Invocation (RMI) provides a flexible kind of Remote Procedure Call (RPC). Unlike RPC, RMI supports polymorphism, which requires the system to be able to download remote classes into a running application. Sun’s RMI implementation achieves this kind of flexibility at the cost of a major runtime overhe...

In this paper we show how to enhancing the Java RMI framework to support object groups. The package we have developed allows programmers to dynamically deal with groups of servers all implementing the same interface. Our group mechanism can be used both to improve reliability preventing system failures and to implement processor farm parallelism. Each service request dispatched to an object gro...

In this paper we describe how to realize a Java RMI framework supporting multi-point method invocation. The package we have realized allows programmers to build groups of servers that could provide services in two different modes: fault tolerant and parallel. These modes differ over computations failure. Our extension is based upon the creation of entities which maintain a common state between ...

This paper discusses the impact of Aspect oriented programming (AOP) on Java-based communication middleware (Java RMI) system and need to introduce aspects in Java RMI systems. There are certain properties like tracing, exception handling, distribution and profiling in Java RMI system which we cannot encapsulate properly using object oriented programming and lead to the problem of code tangling...

Of two distributed object models for use with Java: CORBA and RMI. In the paper we presents performance. Important differences between CORBA and RMI.Both CORBA and RMI hide the communications details of. Therefore from now on we will compare RMI only to the CORBA object request broker. ORB.Systems developers will have to choose between interoperability where Web Services have advantages, and pe...

The Remote Media Immersion (RMI) system is the result of a unique blend of multiple cutting-edge media technologies to create the ultimate digital media delivery platform. The main goal is to provide an immersive user experience of the highest quality. RMI encompasses all end-to-end aspects from media acquisition, storage, transmission up to their final rendering. Specifically, the Yima streami...
