    With the reduction of distances between wires in deep sub-micron technologies, coupling capacitances become significant. This increase of capacitance causes noise capable of propagating a logical fault. Poor evaluation of the crosstalk could be at the origin of a circuit malfunction. In this paper, we propose a new closed form expression for the crosstalk between two, three and five lines. Results... View full abstract»

    In this paper, we present results of the PCG (phonocardiogram) signal analysis using the STFT (Short-Time Fourier Transform). Because of the nonstationarity of the PCG signal, it is important to maintain an analysing time window as short as possible to guaranty the stationarity hypothesis over small analysed segments. This will reduce the frequency resolution of the resulting spectrogram. However ... View full abstract»

    In this paper, we propose shape features that are based on MPEG-4 compressed domain shape information. These shape features can be used for efficient retrieval of both MPEG-4 video objects and video object planes. The proposed shape descriptors are invariant of the shape size, translation, and rotation. Because the shape descriptors are computed using the MPEG-4 compressed domain information, extr...

    The study of electrocardiograph signals (ECG) in the time or in the frequency domain taken separately doesn't allow the detection of arrhythmia and late potentials. But, the study of ECG in the time/frequency domain gives to the physician more information and provides him with a tool for diagnosis specially for cardiac late potential. For nongaussian signal, the application of second order statist... View full abstract»

    In sparse deconvolution two interrelated problems have to be addressed: detection of the peaks of a sparse signal and estimation of their amplitudes. The detection part is a highly nonlinear combinatory problem. Once a solution for the peak positions is obtained, their amplitudes can be estimated analytically. Based on genetic algorithms (powerful optimisation techniques inspired by Nature paradig... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (328 KB)

    One generic approach to determine the angular speed and angular position measurements of a motor or a vehicle is by implementing pulse generator followed by a counter. Typically, the output-frequency of a pulse generator varies proportionally to the motor speed. The main purpose of a counter is to convert this frequency “modulated” (FM) signal to an amplitude modulated (AM) signal. In ... View full abstract»
