    In this paper, the tool "sniffer" is introduced and controlled as a sensor by the IDS via mobile agents; these agents gather intrusion detection data and send them back to the server for analysis. We propose a distributed intrusion detection system (DIDS) which detects intrusion from outside the network segment as well as from inside using mobile agents. The proposed model consists of three major ... View full abstract»

    High dimensional and high-resolution gene expression data generated by the in situ hybridization (ISH) technique provides biologists a powerful tool to study gene functions. Nevertheless, a major challenge in analyzing such data is how to efficiently retrieve genes showing certain spatial expression patterns and/or genes showing similar expression patterns as the query gene. The development of a f... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (130 KB) | HTML iconHTML

    Density clustering algorithms are usually inefficient. Moreover, most of the density clustering algorithms needs an uncertain parameter of c which indicates the expecting amount of clusters. It makes the clustering results randomized by the unreasonable choice of c. And some non-density clustering algorithms also need such a parameter to be a precondition. So the inefficiency and random results of... View full abstract»

    Stationarity is often found in session-to-session transfers of brain computer interfaces (BCIs). To cope with the problem, a framework based on common spatial patterns (CSP), linear discriminant analysis (LDA), and covariate shift adaptation methods is proposed. Covariate shift adaptation is an effective method which can adapt to the testing sessions without the need for labeling the testing sessi... View full abstract»

    A fully digital sensor-actuator has been developed for photoplethysmographic (PPG) measurements. Instead of classical sensor it uses standard light emitting diodes (LEDs) for both light emitting and detecting. Time-duration based conversion protocol is implemented by a field programmable gate array (FPGA) avoiding the need for analog amplifiers and precision analogue to digital converters (ADCs). ...

    Constrained by the symmetries of its Gaussian elements, traditional ECG dynamic model has difficulty in accurately representing complicated ECG waveforms. In order to overcome to this limitation, this paper proposes a generalized EDM by introducing asymmetric Gaussians into the model instead of symmetric ones. The generalized EDM is then applied to the model-based ECG denoising framework using an ... View full abstract»
