Abstract: This article presents a voltage-mode universal bi-quadratic filter performing completely standard functions: low-pass, high-pass, band-pass, band-reject and all-pass functions, based-on Current Controlled Current Differencing Buffered Amplifiers (CCCDBAs) TOW-THOMAS mode equivalent. The features of the circuit are that: the quality factor and pole frequency can be tuned orthogonally via the input bias currents: the circuit description is very simple, consisting of merely few CCCDBAs and grounded capacitors. Without any external resistors and using only grounded elements, the proposed circuit is very comfortable to further develop into an integrated circuit. The PSPICE simulation results are depicted. The given results agree well with the theoretical anticipation.

Abstract: The size and the complexity of the educational system continue to expand as the population and economy grows. Educational planners and administrators have been witnessing a steady growth in the amount and variety of information that has been collected and made available to them. With this growing pressure of information revolution and knowledge explosion, the informational requirements of educational planning and management are tremendous. There are various decision-makers, like employers, planners and administrators, who are continuously engaged in the process of educational planning and management. It is important for each one of them to have reliable and relevant information they require for decision-making in education. This paper presents a solution to this problem with the development and deployment of a National Information System on Agricultural Education Network in India (NISAGENET) using the .NET technology.NISAGENET is a unified system for collection, compilation and analysi
