Electric Heating Cable Fault Testing System Based on Wavelet Packet and RBF Neural Network
A new method for testing of the electric heating cable fault was proposed,which was based on the wavelet packet and RBF (radial basis function) neural network. The principle used for testing the short-circuit fault of the electric heating cable was described. The flow chart of the detecting system was given. Experimental results showed that the method, which combined the wavelet packet and RBF neural network, could be used to improve the effectiveness of locating the electric heating cable fault.
Development and application of electrical heating cable breakdown testing system
In recent years, the electrical heating cable breakdown testing system is used widely. Its electrical heating cable is under the floor, and it is not essy for us to find the cable breakdown. The electrical heating cable breakdown test system is specially designed for testing cable breakdown. The measure of hardware design and realization is mainly discussed. The paper also presents the theory of testing in detail. In praitical application, the system shows stable, and it can test conductor interrupted and conductor short-ciucuit in electrical heating cable accurately.
Roman Homosexuality: Ideologies of Masculinity in Classical Antiquity
This comprehensive study of Roman sexuality and the ideologies of masculinity discusses a wide range of ancient texts, arguing that native Roman concepts of masculinity did not rely on the distinction between homosexuality and heterosexuality, but were instead structured around such antitheses as free versus slave, dominant versus subordinate, and masculine versus effeminate.
