Simple and High-Accuracy Digital Computer Control of Hot Strip Coil Temperature

To get the low temperature transformation product of austenite, study of cooling behavior of coil is essential. Temperature distribution profile of the hot strip coil has been determined by using finite volume method (FVM) vis-à-vis finite difference method (FDM). It has been demonstrated that FVM offer greater computational reliability in estimation of contact pressure distribution and hence the temperature distribution for curved and irregular profiles, owing to the flexibility in selection of grid geometry and discrete point position, Moreover, use of finite volume concept allows enforcing the conservation of mass, momentum and energy, leading to enhanced accuracy of prediction.

End Tidal

The use of a small digital computer to control a number of interactive physiological variables is demonstrated. It is shown that by monitoring the values of end tidal per cent CO2, inspired O2 percentage and mean arterial blood pressure, a computer-controlled system can regulate the ventilation and anaesthesia of an animal within fine tolerances. Similarly it is shown that by controlling the infusion of muscle relaxant, the integrated electromyogram of a muscle can be maintained at any desired level. The computer control system automatically allows for random disturbances in system parameters in maintaining set levels of the controlled variables. The system responds rapidly to changes in the desired level of variables, and prescribed time courses of variables can be followed.
