A fuzzy decision system is constructed based on experiences and techniques of stock and future opportunist. The fuzzy rules are optimized by taking exchange volume into account for better fitting the stock market of mainland China...
This paper describes a high-dynamic-range 2.4 Hz-to-10 kHz wide-range tunable 5th-order Butterworth lowpass filter for biomedical applications. A differential gm-C topology in conjunction with a subthreshold-biased wide-gm-range OTA realizes efficiently a wide frequency tuning capability. For capacitance savings with consequent silicon area reduction, a merged use of floating real capacitor and grounded...
By analyzing the problems of using RFID technology, RFID-based information sharing platform is put forward in this paper, in which a number of industries and systems are integrated, in addition user authentication issues are analyzed and a simple authentication scheme is designed. The establishment of the platform solves the issue of resource sharing and avoids duplication of investment; it also solves...
The performances of different off-line methods for two different electroencephalograph (EEG) signal classification tasks-motor imagery and finger movement, are investigated in this paper. The classifiers based on linear discriminant analysis (LDA), quadratic discriminant analysis (QDA), kernel fisher discriminant (KFD), support vector machine (SVM), multilayer perceptron (MLP), learning vector quantization...
