Information about waste water from the manufacture offibreboard is given, and in this connection a classification of suspended and dissolved impurities occurring in the waste water of fibreboard mills is made. The influence on the concentration and the total amount of such impurities are discussed as a function of the extent of closing of the process wa ter system. Various methods of treatment ...

Rhythmic movements are often controlled by systems containing coupled subnetworks whose oscillations are of different frequencies. We show how fast inhibition from the pyloric network interacts with a slow modulatory input to control the frequency of the gastric mill rhythm of the crustacean stomatogastric ganglion. We deduce that the timing of the pyloric input is crucial in determining what a...

this paper is concerned with investigations into the effect of tension between the stands of the finishing mill on width control in a hot rolling process. an analysis is given to predict satisfactorily the variation in width due to spreading and also due to strip tension between the stands. wusatowskis model which is developed to give an account of spreading is specified and a similar model to ...

Quality inspection is an indispensable part of modern industrial manufacturing. Steel as a major industry requires constant surveillance and supervision through its various stages of production. Continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. Once the slab is released from the casting unit, th...

Several generalized state-space models arising from a semi-discretization of a controlled heat transfer process for optimal cooling of steel profiles are presented. The model orders differ due to different levels of refinement applied to the computational mesh. 1 The model equations We consider the problem of optimal cooling of steel profiles. This problem arises in a rolling mill when differen...
