    Opis:
    In this paper we proposes a synthesis of different mathematical models of power electronic converters based on Thevenin/Norton equivalent circuits. Those models, composed by impedances and harmonic noise sources, are helpful to predict the conducted ElectroMagnetic Interferences (EMI) generated by converters connected to the electrical network. Moreover, the extracted impedances are determining for sizing EMC filters. The proposed analytical model is tested with PSpice simulations and validated by experimental measurements, from DC frequency until 30MHz.

    Opis:
    In this study, Sb₂O₃ (Sb₂O₅) and Ta₂O₅ are used as co-dopants with TeO₂ to stabilize the delta phase of bismuth oxide (δ -Bi₂O₃). Some compositions with formula (1-x) BiO_{1.5}-(x/4) Sb₂Te₂O₉ and (1-x) BiO_{1.5}-(x/4) Ta₂Te₂O₉ (x=0.1, 0.2, 0.3, 0.6, and 0.9) have been synthesized by solid state reaction at 850°C and characterized by powder X-ray diffraction. The Bi_{0.9}Sb_{0.05}Te_{0.05}O_{1.575}, Bi_{0.9}Ta_{0.05}Te_{0.05}O_{1.575} and Bi_{0.8}Ta_{0.1}Te_{0.1}O_{1.65} retain a cubic fluorite structure of δ -Bi₂O₃ phase. The electric properties were studied by impedance spectroscopy. All samples were evaluated by calculating conductivities and activation energies. Various impedance model including constant phase element and the Warburg impedances have been used to interpret the Nyquist representations of electrical analyses.

    Opis:
    The aim of this study was to determine the physicochemical composition of water intended for human consumption in several regions of El-Oued - Algeria. Excess minerals in drinking water, including magnesium, calcium, sulfates, chloride and fluorides play a fundamental role in the prevention of urinary calculi, which are formed mainly from calcium oxalate. The results revealed that wholes water samples are analyzed magnesium ([Mg 2+] > 50 mg / L). The rate of sulfate ions average 638 mg / l, exceeding the maximum allowable concentration (MAC) recommended by WHO ([SO42ˉ] > 250 mg / L). In addition, 85 % had excess fluoride [Fˉ] > 0.85 mg / L, and 100 % are calcium, the rate of Ca2+ is greater than 150 mg / L.

    Opis:
    In this paper we address the problem of managing social interactions between a human user and a set of social agents in structured environments. These agents have to regulate a measurable characteristic of the user. Our study focuses mainly therapeutic, caring for elderly people and assessment applications. The agent concept considered in this study is suitable for multi-robot systems (physical, service, mobile or not), but also to virtual agents (avatars) in a virtual reality (VR) application. The proposed approach has been adapted for an application of social phobia treatment using virtual reality. Thus, we conducted a case study to show the effectiveness of our contribution.

    Opis:
    The field of control of redundant articulated mechanical systems requires the use of algorithms to compute the inverse kinematics. The fields of animation, virtual reality or game in particular, are very interested in these algorithms. We propose in this paper a comparison between several algorithms of incremental type. The considered application concerns the accessibility evaluation of an environment used by a handicapped person (an apartment, a house, an institution…). The physical disability involves a particular characteristic of the human articulated structure that gives rise to constraints that must be taken into account in computing the inverse kinematics.
