Abstract Moderne Dampfkesselanlagen sollen möglichst lange im Dauerbetrieb ohne Beaufsichtigung laufen können. Die zuverlässige, automatische Überwachung aller kritischen Stellen und Parameter wie Füllstand oder Leitfähigkeit des Kesselwassers gewährleistet das SP

Modifications to the Gustafson method of age estimation from teeth are described. They are designed to minimise the subjective nature of the scoring technique and to quantify the regressive changes in the enamel, dentine and cementum. Randomly selected teeth from 25 Indians were examined by the Gustafson method and by our own modification. It was shown that our modified method resulted in more ...

We present an explicit expression for the q-difference system, which the BC1type Jackson integral (q-series) satisfies, as first order simultaneous q-difference equations with a concrete basis. As an application, we give a simple proof for the hypergeometric summation formula introduced by Gustafson and the product formula of the q-integral introduced by Nassrallah–Rahman and Gustafson.

27 Anatomy predicts that mammalian retinas should have in excess of 12 physiological channels, 28 each encoding a specific aspect of the visual scene. Although several channels have been 29 correlated with morphological cell types, the number of morphological types generally exceeds 30 the known physiological types. Here, we attempted to sort the ganglion cells of the mouse retina 31 purely on ...

Pressure–volume–temperature properties are very important in the reservoir engineering computations. There are many empirical approaches for predicting various PVT properties based on empirical correlations and statistical regression models. Last decade, researchers utilized neural networks to develop more accurate PVT correlations. These achievements of neural networks open the door to data mi...

The dynamics of fermentation processes are very complex and not completely known. Some state variables are nonmeasurable, and the process parameters are strongly time dependent. Recently, there are some control methods like fuzzy learning and neural networks, which are promising in dealing with non-linearity, complexity, and uncertainly of these processes. These methods are suitable for the mod...
