This paper introduces a framework and results of analyzing the hepatitis data with combination of temporal abstraction and data mining methods. In particular, we developed a novel temporal abstraction technique for temporal data irregularly collected in a long period suitable for hepatitis data, and we applied mining methods to data abstracted by the… (More)
The artifacts caused by various factors, EOG (electrooculogram), blink and EMG (electromyogram), in EEG (electroencephalogram) signals increase the difficulty in analyzing them. In addition, EEG signals containing artifacts often cannot be used in analyzing them. So, it is useful and indispensable to eliminate the artifacts from EEG signals. A neural… (More)
An optical triplexer with cascaded multi-mode interference (MMI) couplers is proposed in an optical access system. The optical triplexer is constructed on a silicon-on-insulator (SOI) substrate. The optical triplexer was designed by use of beam propagation method.
