computerized can bring to the library services in the near future. Traditionally‚ library systems are implemented manually. Forms are given to Librarian and they fill them of using pens. Afterwards‚ the school administrators process them manually and complied on large bulky file cabinet. Indeed‚ the manual Library System is very costly‚ time consuming and hard task. The primary complaint of school administrators with this system is the tiresome task of searching through records just to verify your query data

functions have certain basic characteristics that permit transient and steady-state analyses of the feedback-controlled system. Five factors of prime importance in feedback-control systems are stability‚ the existence and magnitude of the steady-state error‚ controllability‚ observability‚ and parameter sensitivity. The stability characteristic of a linear time-invariant system is determined from the system’s characteristic equation. Routh’s stability criterion provides a means for determining stability

Circulatory System The human body is made up of many different systems that perform our basic life functions. One such system is the circulatory system. This system transports oxygen and nutrients to organs and tissues within the body and carries away waste products. In performing these functions the circulatory system is associated with other systems in the body. The circulatory system is made up of the heart‚ blood and blood vessels. The heart is the main component of the circulatory system. It

P1 – State three purposes of pneumatic supply system for a typical piston engine powered light aircraft‚ and give the functions of the piston engine air compressor and receiver‚ within the system. An aircraft powered by a piston engine usually tends to have a pneumatic air supply system. This allows the function of different systems on the aircraft that are essential to the flight of the aircraft. In a newer system the supply system will provide a vacuum of air for the gyro’s‚ so that the de icing

types of information systems including but not limited to: Expert systems (Characteristics‚ advantages and disadvantages) Expert systems In artificial intelligence‚ an expert system is a computer system that emulates the decision-making ability of a human expert. Expert systems are designed to solve complex problems by reasoning about knowledge‚ like an expert‚ and not by following the procedure of a developer as is the case in conventional programming. The first expert systems were created in the
