Research ArticleOpen accessIn the abstractThermal Performance of a Solar Heat Storage Accumulator Used For Greenhouses ConditioningMejdi Hazami, Sami Kooli, Meriam Lazaar et al.The use of solar energy for greenhouse heating has gained an increasing acceptance during the last years. Active solar systems applied to greenhouses can supply a significant part of the heating requirements. However, there are some problems related to the cost of the heat collection unit and the heat storage methods. In this context several techniques were born. The most … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 7,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesigning and Building an Automatic Information Retrieval System for Handling the Arabic DataIbrahiem M.M. El Emary, Ja'far AtwanThis paper aimed to design and build an Automatic Information Retrieval System to handle the Arabic data. Also, this paper presents some type of comparison between the retrieval results using the vector space model in two different indexing methods: the full-ward indexing and the root indexing. The proposed Automatic Information Retrieval system was implemented and built using a traditional model … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,890 accessesView PDFCite
Research ArticleOpen accessIn the abstractTest of a Data Basis Oriented Object after Phase of ConceptionSoumia Layachi, M. T. LaskriThe concepts of the approach object introduce cause a lot of interest and make a large topic of survey of it. These concepts applied to the data base are going to allow us to master the complexity of the data base and facilitate us their reuse. If one considers the conception of a data basis oriented object a lot of … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,721 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
Research ArticleOpen accessIn the abstractA New Model for Multi-agent Case-base Reasoning SystemsAbdel Badeea Salem, Aldahoud Ali, Ibrahiem M. M. El EmaryMulti-Agent Systems (MASs) and Case-Based Reasoning (CBR) are two recent and hot paradigms in artificial intelligence field. CBR is a reasoning methodology based on old experience reasoning or similarity-based reasoning while MAS is a new paradigm to organize AI applications. CBR offers multi-agent systems the capability of autonomously learning from experience. This study examines the integration of CBR, MASs and … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 5,157 accessesView PDFCite
Research ArticleOpen accessIn the abstractEclecticism Beyond Orthodoxies: African Social Science Research in the Fight Against HIV/AIDSAmbe-Uva T. NomThis study examines the importance of social science research on HIV/AIDS in Africa. There is a dearth of social science research on HIV/AIDS epidemic in Africa as available literature focus essentially on biomedical and epidemiological aspect of HIV/AIDS research and behavioral changes. In Africa however, efforts at preventing and mitigating the impact of HIV/AIDS epidemic will have to consider the … …Journal of Social Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 6,973 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Total Productivity PCA Model for Assessment and Improvement of Electrical Manufacturing SystemsAli Azadeh, Farid GhaderiThis study presents a framework for assessment of electrical manufacturing systems based on a total machine productivity approach and multivariate analysis. Furthermore, the total model is developed by Principle Component Analysis (PCA) and validated and verified by Numerical Taxonomy (NT) and non-parametric correlation methods, namely, Spearman correlation experiment and Kendall Tau. To achieve the objectives of this study, a comprehensive … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,275 accessesView PDFCite
Research ArticleOpen accessIn the abstractHemisphere Sizing from Linear Intercept MeasurementWilfried GilleThe stereological problem of unfolding the hemisphere radius distribution from the chord length distribution is analyzed. Let a stationary isotropic process of hemispheres be given. The hemispheres have random diameters and are isotropically uniformly randomly orientated in space. A straight line probe yields a process of intercepts. The inverse problem of re-obtaining the size distribution of the hemispheres in terms … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,149 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Bit Error Rate Performance of Multi Tone Channel Utilising De-OQPSK and De-Off Set 16 QAM with Guard IntervalIbrahim A.Z. QatawnehDigital communications systems use Multi tone Channel (MC) transmission techniques with differentially encoded and differentially coherent demodulation. Today there are two principle MC application, one is for the high speed digital subscriber loop and the other is for the broadcasting of digital audio and video signals. In this study the comparison of multi carriers with OQPSK and Offset 16 QAM … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,849 accessesView PDFCite
