Research ArticleOpen accessIn the abstractExperimental Evaluation of Medium Access Schemes in 802.11 Wireless NetworksG. Singh, B. S. SohiProblem statement: Deployment of real time services over 802.11 wireless networks requires quality of service (QoS) differentiation mechanisms for different traffic types. This required investigations into the performance of the Medium access (MAC) schemes like Distributed Coordinated Function (DCF) and Enhanced DCF with respect to the stringent QoS requirements imposed by the real time services. Motivation for this research was … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 7,136 accessesView PDFCite
Research ArticleOpen accessIn the abstractA case study on Journalistic Coverage for Chinese issues in Saudi NewspapersYahya SharahiliAs Journalism could instinctively exert some effects on international relationships; the importance is how to effectively journalism captures attention. This paper, from the perspective of Saudi-China relationship, chose two renowned Saudi newspapers 'AL RIYADH' and 'AL WATAN', as objective samples. Deductive and descriptive methodologies have been applied to a detailed study on the coverage of Chinese issues in Saudi newspapers … …Journal of Social Sciences, Vol. 4, Issue 1 · 31 Mar 2008 · 7,462 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction of Genomic DNA Using Magnetic Nanoparticles (Fe3O4) as a Solid-Phase SupportZ. M. Saiyed, C. N. RamchandMagnetic separation technology, using magnetic particles, is quick and easy method for sensitive and reliable captures of specific proteins, genetic material and other biomolecules. The current paper describes a universal genomic DNA extraction method optimized in our laboratory using magnetic nanoparticles as a solid phase adsorbent. The yields of the isolated DNA with magnetic method were higher or equivalent to … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 9,826 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Assessment and Monitoring of a Permeable Reactive Barrier for the Remediation of a Contaminated SiteValerio Zolla, Rajandrea Sethi, Antonio Di MolfettaThe present study illustrates the long-term monitoring plan carried out in order to investigate the performance of a zero-valent iron permeable reactive barrier (PRB) at a chlorinated solvents’ site. The cleanup intervention has been undertaken at an industrial landfill located near the city of Turin (Italy) and represents the first full-scale application of this technology in Italy. The monitoring plan … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element and Experimental Serviceability Analysis of HSC Beams Strengthened with FRP SheetsSeyed Hamid Hashemi, Reza Rahgozar, Ali Akbar MaghsoudiThe use of externally bonded composite sheets or laminates is by now a diffuse technique to strengthen existing RC structures. However, some aspects of flexural condition still need experimental and numerical analysis; furthermore, especially for serviceability checks, there is a lack of code provisions. Six reinforced high strength concrete (HSC) beams strengthened with FRP sheets were fabricated and tested, the … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,440 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Innovative Technique of Texture Classification and Comparison Based on Long Linear PatternsV. Vijaya Kumar, B. Eswara Reddy, U. S.N. Raju, K. Chandra SekharanThe present paper proposes a method of texture classification based on long linear patterns. Linear patterns of long size are bright features defined by morphological properties: linearity, connectivity, width and by a specific Gaussian-like profile whose curvature varies smoothly along the crest line. The most significant information of a texture often appears in the occurrence of grain components. That’s why … …Journal of Computer Science, Vol. 3, Issue 8 · 28 Aug 2007 · 6,720 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh-precision Detection of Facial Landmarks to Estimate Head Motions Based on Vision ModelsXiaohong W. Gao, Sergey Anishenko, Dmitry Shaposhnikov et al.A new approach of determination of head movement is presented from the pictures recorded via digital cameras monitoring the scanning processing of PET. Two human vision models of CIECAMs and BMV are applied to segment the face region via skin colour and to detect local facial landmarks respectively. The developed algorithms are evaluated on the pictures (n=12) monitoring a subject’s … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,819 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Detection using Geometric Invariant MomentMohamed Rizon, Haniza Yazid, Puteh Saad et al.Geometric moment invariant produces a set of feature vectors that are invariant under shifting, scaling and rotation. The technique is widely used to extract the global features for pattern recognition due to its discrimination power and robustness. In this paper, moment invariant is used to identify the object from the captured image using the first invariant (Ø1). The recognition rate … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Oct 2006 · 6,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractOntology-based Knowledge Networks for users' training: The Enterprise Resource Planning (ERP) caseMacris AristomenisThis paper presents a prototype model for the design and development of training material, where both the multimedia objects used in training scenarios and the knowledge built into them are captured and fully reusable. Knowledge found in the logic, the structure and the ways of use of domain specific literacy is represented as a knowledge network (a collection of educational … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractBehaviour Patterns of the Pine Processionary Moth (Thaumetopoea wilkinsoni Tams; Lepidoptera: Thaumetopoeidae)Ahmad Houri, Dany DoughanThaumetopoea wilkinsoni is a serious pest of pine trees, especially the wide-spread Pinus brutia. This infestation has a significant economic impact both in the loss of forest wood growth and in medical expenses for treating related human diseases. This paper presents a detailed study of the behaviour patterns of the moth stage in an attempt to identify best control methods. … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 1 · 31 Mar 2006 · 8,695 accessesView PDFCite
