    Pattern matching is one of the basic problems in computer science. In this paper we propose a new multiple pattern matching algorithm. Unlike the well known Knuth-Morris-Pratt, Boyer-Moore, Karp-Rabin and their variants, our algorithm is derived from the ideas of sampling and bit index, sampling for efficiency and bit index for flexibility, as a result providing the simplest way to search for mult...

The heart of almost every IDSs is a string matching algorithm, which is a very computational intensive task. Network Processors (NPs), a specialized multiprocessor, can provide flexibility and high performance for string matching. This paper evaluat... View full abstract»

    This paper proposes a framework for predicting protein three dimensional structures from their primary sequences. The proposed method utilizes the natural multi-label and hierarchical intrinsic nature of proteins to build a multi-label and hierarchical classifier for predicting protein folds. The classifier predicts protein folds in two stages, at the first stage, it predicts the protein structura... View full abstract»

    In this work we compare the use of a particle swarm optimization (PSO) and a genetic algorithm (GA) (both augmented with support vector machines SVM) for the classification of high dimensional microarray data. Both algorithms are used for finding small samples of informative genes amongst thousands of them. A SVM classifier with 10-fold cross-validation is applied in order to validate and evaluate...

    Nanodevices based circuit design will be based on the acceptance that a high percentage of devices in the design will be defective. In this work, we investigate a defect tolerant technique that adds redundancy at the transistor level and provides built-in immunity to permanent defects (stuck-open, stuck-short and bridges). The proposed technique is based on replacing each transistor by quadded-tra... View full abstract»

    Due to the increasing number of elements on a single chip area and the growing complexity of routing, existing methods to reduce crosstalk at the routing or post-routing stage do not seem efficient anymore. So crosstalk estimation should be considered in earlier design stages such as placement. To estimate crosstalk after placement information about the topology of a net and adjacency of its wire-...

    In this paper, we present a new bus coding scheme based on genetic algorithm to eliminate crosstalk delay and to reduce power dissipation. This algorithm can be applied usefully for large width bus, in which it is difficult to find the optimal solution for bus coding. Our bus encoding scheme is capable to eliminate completely crosstalk problems in bus partitions as well as inter-partitions by usin... View full abstract»

    Several approaches have been introduced in literature for active noise control (ANC) systems. Since FxLMS algorithm appears to be the best choice as a controller filter, researchers tend to improve performance of ANC systems by enhancing and modifying this algorithm. This paper proposes a new version of FxLMS algorithm. In many ANC applications an online secondary path modelling method using a whi... View full abstract»
