In oil and gas industry, prior prediction of certain properties is needed ahead of exploration and facility design. Viscosity and gas/oil ratio (GOR), are among those properties described through curves with their values varying over a specific range of reservoir pressures. However, the usual prediction approach could result into curves that are not consistent, exhibiting scattered behaviour as compared to the real curves. In this paper two advances to artificial neural networks are implemented to solve the problem. These are Support Vector Regressors and Functional Networks. Statistical error measures have been used and showed the high performance of the proposed techniques. Moreover, the predicted curves are consistent with the actual curves.

Our present paper deals with the problem of audio speaker localization, which consists in determining the position of the active speaker in a meeting-room. This step represents the first task of speaker tracking, which is the global purpose of our research work. In this approach, two-channel-based (stereo) estimation of the speaker position is achieved by comparing the signals received by two cardioids microphones that are placed the one against the other and separated by a fixed distance. Our localization technique is inspired from the human ears, which act as two different sound observation points, enabling humans to estimate the direction of the speaking person with a good precision. The off-line experiments of speaker tracking have been done in a small meeting room without echo cancelation. Results show the good performances of the proposed localization methods.

In this paper, an algorithm for person verification is proposed. Dempster-Shafer Theory is used for face and voice fusion at the score level in order to overcome the limitations of unimodal biometric systems. Our experiments on the publicly available scores of the XM2VTS Benchmark database show a consistent improvement in performance compared to each individual modality. We have compared our approach with the sum rule and the likelihood ratio based fusion.

In this paper, we address the problem of Mobile Positioning and Tracking in the context of WCDMA mode of UMTS-FDD systems using signals' Time of Arrivals in the Downlink direction. A common method for ToA's estimation is correlation procedure between the received signal and delayed versions of the pilot sequence. This classical estimator suffers from the hearability and Near-Far problems, inherent to the WCDMA systems, and several improvements have been proposed in the literature to combat their effects. In this paper, we propose another ToA's estimator, based on Wiener Channel Estimator, and we combine it with a CACFAR detector in order to increase Fingers' probability of detection. Simulation results show that this new CACFAR Wiener RAKE Receiver operates better than the classical ones especially in the situations where the hearability problem has a hard effect on ToA's estimation.
本文利用UMTS-FDD系统下行方向的信号到达时间，解决了WCDMA模式下UMTS-FDD系统的移动定位与跟踪问题。一种常用的估计ToA的方法是将接收信号与导频序列的延迟版本进行相关处理。这种经典估计器存在WCDMA系统固有的可听性和近距离问题，文献中提出了一些改进方法来对抗它们的影响。在本文中，我们提出了另一种基于Wiener信道估计器的ToA估计器，并将其与CACFAR检测器相结合，以提高finger的检测概率。仿真结果表明，在可听性问题严重影响ToA估计的情况下，这种新的CACFAR Wiener RAKE接收机的性能优于传统的Wiener RAKE接收机。

Classical hidden Markov chains (HMC) can be inefficient in the unsupervised segmentation of non stationary data. To overcome such involvedness, the more elaborated triplet Markov chains (TMC) resort to using an auxiliary underlying process to model the behavior switches within the hidden states process. However, so far, only this latter was considered non stationary. The aim of this paper is to extend the results of a recently proposed TMC by considering both hidden states and noise non stationary. To show the efficiency of the proposed model, we provide results of non stationary synthetic and real images restoration.

Various ECG instruments have addressed a wide variety of clinical and technical issues. However, there is still scope for improvement in them particularly in the area of their susceptibility to noise, lack of universal connectivity and off-line processing. In emergency situations, real-time health parameter is crucial. According to the American Heart Association [1], treatment of a patient experiencing ventricular fibrillation within the first 12 minutes of cardiac arrest brings a survival rate of 48%–75%. The survival rate drops to 2%–4% after 12 minutes have gone. This paper illustrates a low-cost method for realtime acquisition of ECG signal for storage and processing using a Matlab®-based Graphical User Interface (GUI). This costly effective design can be interesting for the third world medical device industry to develop such device locally instead of buying the technology with high cost from the western contries. The ECG device is wirelessly connected to a smart phone or a computer using IEEE 802.15.1 based radio protocol. It includes an analog system and a Bluetooth transceiver, flexible and stretchable for comfortable continuous cardiac monitoring. The Matlab®-based GUI is designed to perform real-time analysis on the ECG data to compute the different waves features and display the same on the GUI along with the ECG signal plot.

In this paper, a new blur reduction method based on the new concept of Multiplicative Multiresolution Decomposition is presented. This method turns on specific corrections of coefficients in MMD domain. To appreciate the proposed approach performances, one could consider the classical method based on Shock filters and blind deblurring. The conventional methods for assessment like PSNR and MSE are invalid since there is no correlation with human perception. Therefore one could propose to use metrics which quantify the quantity of blur in images as it is proposed in [1]. In addition, one could compare the results visually and by plotting an original and deblurred transitions.

In this paper, a new algorithm for ECG waves segmentation is described. The algorithm is based on the wavelet transform for the complex QRS delineation and a surface indicator for the detection of the T-end waves. The described algorithm was evaluated using ECG signals from the universal database MIT BIH. A sensitivity of 99.35% and a positive predictivity of 99.05% are reached. Those obtained results show the good performances of this new algorithm.

by Ecole Nationale Polytechnique of Algiers. This is the 25th Anniversary of WoSSPA and it is the first time that WoSSPA is organized in an African country; and, it follows the successful organization of ISSPA 2007 and WoSPA 2008 in Sharjah, UAE. Previous earlier events were all organized in Australia apart from a joint event organized in Malaysia in 2005, starting from a workshop in 1986 that was in preparation for the first ISSPA held in 1987 in Brisbane, Australia. The name of the event was then WoSPA (Worshop on Signal Processing and its Applications). The word " Systems " in the title was added this year. After 1986, the next WoSPA events were held in 1990 and 1992 as two-day workshops that immediately followed ISSPA 1990 and WoSPA 1992, and they were specialized workshops with time-frequency signal analysis as the 1990 theme and Higher Order Spectra as the 1992 theme. From 1993, WoSPA was organized independently of ISSPA and it was held in between two ISSPAs until now. As for all the previous events, we have emphasized some particular themes: biomedical research, signal processing for communications and Radar Signal Processing as well as other multidisciplinary research. The background for this decision is local, taking into account directions taken by Algerian Researchers. With this workshop, we will have now organized three main high level events (including ISSPA 2007 and WoSPA2008 in Sharjah) in the field of Signal Processing in the Middle East & North Africa region. It was found that, in order for universities in the region to make a significant contribution to the field of Signal Processing, we needed to link those areas of expertise available locally with expatriate researchers in overseas universities. To make this link productive, it was desirable to define clear objectives and efficient strategies. Organizing WoSSPA 2011 is part of this strategy. It aims to take advantage of local expertise to define new multidisciplinary research directions that will need to significant innovation for the benefit of the local, Arab, African and international community. In particular, Algerian researchers participating at WoSSPA 2011 should be able to mingle freely with overseas delegates without the hassles involved in trying to get a visa for events organized in an overseas destination.
