J2EE architecture has many complicated layers, including client. These layers are presentation layer, business logic layer and data persistence layer. There is respective data presentation in relevant layer of J2EE, with strictly rules to access and transform data objects between these layers. This paper brings forward middleware technology which is the kernel and key to the solution of the dynamic E-business system through analyzing J2EE architecture and the most important MVC (Model View Controller) design pattern. It includes the component technology of JSP, Servlet and EJB etc. J2EE technology and MVC design pattern can simplify the software development, improve the software performance and quickly construct the dynamic E-business system of the good expansibility, maintainability, dependability and high usability. The traditional system of industry report is highly influenced by the database security and has low efficiency on report. In order to solve these problems, this paper studies J2EE and MVC architecture, combine them and propose an industry report system which based on J2EE and MVC architecture. The system which makes full advantages of both architecture, has solved the problems such as avoid showing databases pattern to client directly and separating the data persistence layer, business logic layer and presentation layer from each other. It obtains a good result in the web based practical application.

This paper describes the implementation of Hawk Eye Technology. Hawk Eye Technology is a complex computer system used in cricket, tennis and other sports to visually track the path of the ball and display a record of its most statistically likely path as a moving image. It is also used in some instances to predict the future path of a ball in cricket.

Smart dust is a system of many tiny Micro Electro-mechanical systems (MEMS) such as sensors, robots, or other devices, that can detect, for example, light temperature, vibration, magnetism, or chemicals. They are usually operated on a computer network wirelessly and are distributed over some area to perform tasks, usually sensing through radio-frequency identification. Without an antenna of much greater size the range of tiny smart dust communication devices is measured in a few milli-meters.

The primary function of a Union is to promote and protect the interests of its members. It has to advance the social and economic interests of the members. For the purpose, it has to undertake welfare activities like organizing mutual benefits sources, games and cultural programmes and educate its members in all aspects of their working life. In discharging the basic functions the unions have to operate on many fronts, social, economic, civic and political. The bargaining power of an individual is often quite weak because of factors like, ignorance, illiteracy, poverty, indebtedness, social, economic and political backwardness and like so, he is no match for his economically superior employer when he engages in individual bargaining.
