Digital instrumentation and control (I&C) systems have proven to be useful and beneficial in a wide range of applications including fossil-fueled power generation, electric power distribution, petroleum refining, petrochemical production, aerospace, and some nuclear power plant applications (e.g., core protection calculators, diesel generator load sequencers, a few digital reactor protection systems, and plant radiation monitoring systems)…

Introduction


Level sensors are used to detect liquid or powder levels, or interfaces between liquids. These level measurements can be either continuous or point values represented with various output options. Continuous level sensors are devices that measure level within a specified range and give output of a continuous reading of level. Point level sensors devices mark a specific level, generally used as high alarm or switch.
These sensors can be mounted on the top, bottom or side of the container holding the substance to be measured. Among the technologies for measuring level are air bubbler technology, capacitive or RF admittance, differential pressure, electrical conductivity or resistively, mechanical or magnetic floats, optical units, pressure membrane, radar or microwave, radio frequency, rotation paddle, ultrasonic or sonic and vibration or tuning fork technology. Analog outputs level sensors can be current or voltage signals. Also possible is a pulse or frequency. ...

Thus, under an autonomous situation, a controller must be able to manage problems not only with the software but also fix problems arising in the hardware. He also believes that the process of developing a controller with artificial intelligence is evolutionary, ie. each model must evolve as an improvement over the previous one through continuous improvements and compilation and coordination of…

They embarked on a R&D program to develop a suite of Internet based enterprise application software. These applications would work perfectly with Oracle databases. This eradicated the need to hold large numbers of databases on a client/server architecture since the delivery could be achieved through an Internet browser. Having developed the tools, Ellison took another of his great strategic…
