A wearable sensor capable of detecting the presence of humans within a front-facing 90-degree sector of varying radius is demonstrated herein. The system offers extensive applicability across a variety of scenarios where detecting the parameters of human interaction, including separation distance and duration, is of value. Sensing is accomplished using an ultrasonic distance and passive infrared sensor...
We propose an RBF (radial basis function) neural network-based fault localization method to help programmers locate bugs in a more effective way. An RBF neural network with a three-layer feed-forward structure is employed to learn the relationship between the statement coverage of a test case and its corresponding execution result. The trained network is then given as input a set of virtual test cases,...
In this paper, SOM (self-organizing map) neural networks is introduced to Chinese multi-category words. Chinese multi-category words are those words which are of the same Chinese characters and different syntactic functions and meanings. If we only select characters of target sentences as the features of SOM, these multi-category words with the same characters will be mapped in same output nodes,...
