Research ArticleOpen accessIn the abstractIntelligent Sensor for Image Control Point of Eigenfaces for Face RecognitionMohamed Lamine Toure, Zou BeijiProblem statement: The sensor for image control point in Face Recognition (FR) is one of the most active research areas in computer vision and pattern recognition. Its practical application includes forensic identification, access control and human computer interface. The task of a FR system is to compare an input face image against a database containing a set of face samples … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 6,974 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cost Effective and User Friendly Approach to Design Wireline Formation TestsClara Bertolini, Giuseppe Tripaldi, Elena Manassero et al.Problem statement: Wireline formation testing (also named Mini-DSTs) are gaining more and more popularity as a possible alternative to conventional well testing especially where there are major environmental and economical constraints. The increased offshore exploration activity, which often implies highly risky and huge operational costs, makes the conventional well testing less attractive in favor of other technologies that can provide … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 6,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Low Complexity Lossless Coding Algorithm for Medical ImagesS. E. Ghrare, M.A. Mohd. Ali, K. Jumari, M. IsmailProblem statement: Nowadays a large number of various medical images are generated from hospitals and medical centers with sophisticated image acquisition devices, the movement toward digital images in radiology presents the problem of how to conveniently and economically store, retrieve and transmit the volume of digital images. Thus digital image data compression is necessary in order to solve this problem. … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeterogeneous Modeling, Identification and Simulation of Activated Sludge ProcessesIbrahim H. Mustafa, G. Ibrahim, Ali Elkamel, A. H. ElahwanyProblem statement: The activated sludge system is a complex dynamic process and must account for a large number of reactions between large numbers of components. There is necessity for simulation models which describe the dynamic behavior of the activated sludge process. The application of the models in most treatment plants is limited due to lack of appropriate data acquisition and … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,592 accessesView PDFCite
Research ArticleOpen accessIn the abstractActive Fire Monitoring with Level 1.5 MSG Satellite ImagesAbdelatif Hassini, Farid Benabdelouahed, Noureddine Benabadji, Ahmed Hafid BelbachirThe first of the new generation of Meteosat satellites, known as Meteosat Second Generation (MSG-1), was launched in August 2002. As with the current Meteosat series, MSG is spin-stabilized and capable of greatly enhanced Earth observations. The satellite’s 12-channel imager, known formally as the Spinning Enhanced Visible and Infrared Imager (SEVIRI), observes the full disk of the Earth with an … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 8,130 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study of Near Wake Flow Behind a Rectangular CylinderAbdollah Shadaram, Mahdi Azimi Fard, Noorallah RostamyThe turbulence characteristics of the near wake flow behind a rectangular cylinder is investigated in a two-dimensional analysis using a hot-wire anemometer. The time-averaged and fluctuating components of the velocity are measured for a cylinder having various width-to-height (b h-1) ratios. The measurements are carried out in a low-speed wind tunnel. Data from hot-wire anemometer is collected by a data … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,270 accessesView PDFCite

Research ArticleOpen accessIn the abstractOperating System Support for Wireless Sensor NetworksAnt A. Fröhlich, Lucas F. WannerIn a wireless sensor network, several sensor nodes obtain local data and communicate among themselves in order to create a global vision of an object of study. The idea of a self-managed network of low-power, autonomous devices, that collects data from an environment and propagates information through a wireless link brought about several new challenges and requirements in application run-time … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractContribution of the Entropy Function to the Study of Collimator for Nuclear Medicine ImagingM.S. Bouhdima, I. Elloumi, M.H.B. GhozlenScintigraphic image currently used in the diagnosis or the evaluation process of tissues, is strongly dependant on several technical parameters specially collimator characteristics. The present work describes a numerical method, based on entropy function, able to specify depth and hole diameter of collimator as well as other geometrical parameters to get a better accuracy in scintigraphy evaluation. From the classical … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 6,737 accessesView PDFCite
