Research ArticleOpen accessIn the abstractAn Evolution Strategy for the Induction of Fuzzy Finite-state AutomataMozhiwen, WanminThis study presents an evolution strategy used to infer fuzzy finite-state automata from examples of a fuzzy language. We describe the fitness function of an generated automata with respect to a set of examples of a fuzzy language, the representation of the transition of the automata as well as the output of the states in the evolution strategy and the … …Journal of Mathematics and Statistics, Vol. 2, Issue 2 · 30 Jun 2006 · 6,699 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimating Soil Contamination with Kriging Interpolation MethodFatima Zohra Benmostefa LarguecheThe main objective of this study was to investigate whether Kriging is a useful tool to estimate the spatial distribution of ground pollutants in contaminated land. The second objective of this work was a more practical one. It consists on the identification of areas that should be subjected to remedial actions and also on deciding which contaminant needs to be … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Jun 2006 · 8,292 accessesView PDFCite
Research ArticleOpen accessIn the abstractHighly Efficient Elliptic Curve Crypto-Processor with Parallel GF(2m) Field MultipliersTurki F. Al-Somani, M. K. Ibrahim, Adnan GutubThis study presents a high performance GF(2m) Elliptic Curve Crypto-processor architecture. The proposed architecture exploits parallelism at the projective coordinate level to perform parallel field multiplications. In the proposed architecture, normal basis representation is used. Comparisons between the Projective, Jacobian and Mixed coordinate systems using sequential and parallel designs are presented. Results show that parallel designs using normal basis gives … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,877 accessesView PDFCite
Research ArticleOpen accessIn the abstractSupporting Tools to Simplify the Navigation Process over the WebChabane Khentout, Mahieddine Djoudi, Lamri DouidiWe Navigation through the Web has problems of positioning and space-temporal reference marks. Therefore, it’s necessary to design some computer-aided tools to help the user to position himself in space and time during a navigation session. The user is provided with a map of visited sites, thus giving an explicit representation of virtual space. Various levels of visualization are set … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,675 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrom Design Specification to SystemCRachid Boudour, Mohamed T. KimourIn this paper, we present a framework for transforming the design model into SystemC code. Such a framework uses as input UML state machine and object diagrams, which are more and more used as design models in embedded systems. To do this, we have firstly used Poseidon tool for editing the design model and generating the XMI representation, and secondly … …Journal of Computer Science, Vol. 2, Issue 2 · 28 Feb 2006 · 7,207 accessesView PDFCite
Research ArticleOpen accessIn the abstractSplitting Technique Initialization in Local PCAAlok Sharma, Kuldip K. Paliwal, Godfrey C. OnwuboluThe local Principal Component Analysis (PCA) reduces linearly redundant components that may present in higher dimensional space. It deploys an initial guess technique which can be utilized when the distribution of a given multivariate data is known to the user. The problem in initialization arises when the distribution is not known. This study explores a technique that can be easily … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,725 accessesView PDFCite
Research ArticleOpen accessIn the abstractLinear Smoothing of Noisy Spatial Temporal SeriesValter Di Giacinto, Ian dryden, Luigi ippoliti, Luca RomagnoliThe main objective of the study is the development of a linear filter to extract the signal from a spatio-temporal series affected by measurement error. We assume that the evolution of the unobservable signal can be modelled by a space time autoregressive process. In its vectorial form, the model admits a state space representation allowing the direct application of the … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,314 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeta Architecting: Towered a New Generation of Architecture Description LanguagesAdel Smeda, Tahar Khammaci, Mourad OussalahThe techniques of meta-modeling and meta-levels have become a mature concept and have been largely used to solve real problems in programming languages, distributed environments, knowledge representation, or data bases. In this article it is shown how the same techniques can be applied in component-based software architecture. It also shown the need to propose mechanisms of reflexivity within the domain … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,483 accessesView PDFCite
Research ArticleOpen accessIn the abstractPattern Classification: An Improvement Using Combination of VQ and PCA Based TechniquesAlok Sharma, Kuldip K. Paliwal, Godfrey C. OnwuboluThis study firstly presents a survey on basic classifiers namely Minimum Distance Classifier (MDC), Vector Quantization (VQ), Principal Component Analysis (PCA), Nearest Neighbor (NN) and K-Nearest Neighbor (KNN). Then Vector Quantized Principal Component Analysis (VQPCA) which is generally used for representation purposes is considered for performing classification tasks. Some classifiers achieve high classification accuracy but their data storage requirement and … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,504 accessesView PDFCite
