Abstract: The present application relates to a system and a method for producing vinyl chloride. The system comprise a preheat unit, a gas-liquid separating unit, a heat-recovery unit, a heating unit and a thermal pyrolysis unit, and therefore heat energy of the thermal pyrolysis product can be efficiently recovered. Energy cost of the system can be efficiently lowered with the heat-recovery unit and the heating unit, and further prolonging operating cycle of the system.

Abstract: A method for predicting sleep apnea from neural networks that mainly includes the following steps: a) retrieving an original signal; b) retrieving at least one snoring signal from the original signal by a snoring signal segmentation algorithm and converting the snoring signal into one with one-dimensional vector; c) applying a feature extraction algorithm to process the snoring signal with one-dimensional vector and transform the snoring signal into a feature matrix of two-dimensional vectors; and d) classifying the feature matrix by a neural network algorithm to obtain the number of times of sleep apnea and sleep hypopnea from the snoring signal. The method thereby is able to decide whether the snoring signal has revealed indications of sleep apnea or sleep hypopnea or not.
