The suitability of artiicial neural networks (ANNs) for detecting fault conditions in pneumatic control valve actuators is investigated. Speciically, the ability of a neural network to act as a predictor of correct valve behaviour is examined. Experimental results indicate that standard network architectures are unsuitable for temporal prediction of non-linear system behaviour. An original recu...

The main objective of this project was to investigate the behavior and the damaging effects of hot tear segregations in the continuously cast steel blooms on the final product quality. To achieve this aim, plant data from three different types of steels were used. Investigations using the scanning electron microscope (SEM) equipped with energy dispersive x-ray spectroscopy (EDS) probe and metal...

Background and Purpose: Dacryocystography or visualization of nasolacrimal duct has been widely used in the assessment of the nasal lacrimal system. The water-soluble agent iohexol is currently widely used in nervous and vascular lesion in diagnostic radiology and also employed in dacryocystography. This study was performed to determine the effects of iohexol on tear parameters in normal donk...

BACKGROUND The study sought to determine dynamic changes and theoretical bases of a clinical diagnostic test, the tear clearance rate. METHODS Thirty four healthy subjects ranging in age from 22 to 84 years underwent examination of tear clearance rate, the Schirmer test with anaesthesia, as well as fluorophotometric measurement of tear turnover, tear volume, and tear flow. By applying 0.5% fl...
