—In this work a new fast training algorithm for the multilayer perceptron (MLP) is proposed. This algorithm is based on optimising a criterion formed from the Mean Squared and Mean Fourth power errors, resulting in a modified form of the Standard Back-Propagation (SBP) algorithm. In this criterion, the mean fourth power error signal is appropriately(More)

Nowadays medical technology makes the inevitable trend of an ageing population. So intelligent home care is an important direction of development of science and technology, in particular, elderly in-home safety management issues become more and more important. In this research, we propose a low of operation algorithm and use the triangular pattern rule,(More)
A speech transmission method is presented to transmit an audible sound wave by an ultrasonic carrier frequency modulation with a characteristic of directional propagation. The modulated sound wave is propagated with the ultrasonic carrier to the appointed position, and then the original speech will be produced after getting rid of the ultrasonic carrier,(More)
