    Despite their importance and success, popular Search Engines do not take into account all user sensitivities when filtering results. Their filtering capabilities are mainly limited to adult content prevention. However, this filtering may not be enough for users that are sensitive to other kinds of content. By not taking into account all user sensitivities, Search Engines are limiting how users may... View full abstract»

    It is well known that HARQ technique generates delays du to the retransmissions. Thus, the high speed real time services quality, in High Speed Downlink Packet Access (HSDPA), depends on the number of the retransmissions. Motivated by the important diversity that multiple transmitting antennas and multiple receiving antennas (MIMO) can provide, we study the possibility to avoid HARQ retransmission...

    The deployment of wireless sensor networks in many application areas requires self organization of the network nodes into clusters. The clustering Algorithm is a kind of key technique used to reduce energy consumption. Efficient way to enhance the lifetime of the system is to partition the network into distinct clusters with a high energy node as cluster head. The different methods of node cluster...

    Knowledge Discovery in Databases (KDD) is a highly complex, iterative and interactive process involving several types of knowledge and expertise. In this paper we propose to support users of a multi-view analysis (a KDD process held by several experts with different viewpoints). Our objective is to enhance both reusability of the process and coordination between experts. To do so, we propose a for... View full abstract»
