Power quality influences the operating conditions of a power network, having important technical and economic implications over the power consumption and also on the security of the power network's operation environment. Therefore, the power grid operators are found in the position to search for the best tools capable to convert huge volume of heterogenous information into knowledge, briefly and easily understandable and available to a large category of execution personnel. The content of this paper gravitates on a web-based tool designed for a general evaluation and geographical visualization of the power quality level in the power distribution grids - MAPPQ (Mapping of the power quality).

Recently javaprogramming environment has become so popular. java programming language is a language that is designedto be portable enough to be executed in wide range of computers ranging from cell phones to supercomputers. Computer programs written in java are compiled into java Byte code instructions that are suitable for execution by a java Virtual Machine implementation. java virtual Machine is commonly implemented in software by means of an interpreter for the java VirtualMachine instruction set. As an object oriented language, java utilizes the concept of objects. Our idea is to identify thecandidate objects' references in a java environment through hierarchical cluster analysis using reference stack and execution stack.

The use of computer programminglanguage, java and open source in enterprise resource planning systems, is discussed. Virtually every company has some sort of management IT system. One can automate what might have been a manual process by building business rules into the software. It is observed that more powerful hardware and more sophisticated software have together enabled a whole new level of functionality that can seriously change businesses for the better.

This paper presents a new static type system for multithreaded programs; any well-typed program in our system is free of data races. Our type system is significantly more expressive than previous such type systems. In particular, our system lets programmers write generic code to implement a class, then create different objects of the same class that have different objects of the same class that have different protection mechanisms. This flexibility enables programmers to reduce the number of unnecessary synchronizationoperations in a program without risking data races. We also support default types which reduce the burden of writing extra type annotations. Our experience indicates that our system provides a promising approach to make multithreaded programs more reliable and efficient

The Safety Critical java and Mission Critical java standard efforts were developed. Safety critical java prunes the RTSJ, keeping it functional while reducing complexity. The new standard also makes a number of additions such as address scoped memory and other eliminated features. It was found that java can span the market from a static, fixed allocation embedded environment to a dynamic, server based Web service.

Events are used in distributed systems for monitoring purposes since internal states are often hidden from the observer. Composite events are recursively defined events upon conditions involving other events and occur whenever those conditions are satisfied. In systems where conditions on the occurrences of multiple events need to be monitored, composite events are extremely useful for clarifying the semantics of the conditions to be monitored and the correlation of simpler events. In this paper, we present a composite event package in java called JEM, which accepts and monitors the composite events specified in a java Event Specification language (JESL). JESL is developed based on a unified formalism presented in [14] for composite event and timing constraint specification. The system structure of JEM and its major components, i.e. Event Subscription Server;Composite Event Compiler and Monitor, are described in the paper. Some performance experiment results and the scalability issue of JEM are also discussed. The paper also demonstrates the practicality of JEM by explaining how a network event correlation application is built using JEM.
