Research ArticleOpen accessIn the abstractFace Biometrics Based on Principal Component Analysis and Linear Discriminant AnalysisLih-Heng Chan, Sh-Hussain Salleh, Chee-Ming TingProblem statement: In facial biometrics, face features are used as the required human traits for automatic recognition. Feature extracted from face images are significant for face biometrics system performance. Approach: In this thesis, a framework of facial biometric was designed based on two subspace methods i.e., Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA). First, PCA is used for … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractLisrel Analysis of Factors for Empowering Producers to Abolish Livelihood Poverty through Optimizing Agricultural Water Resources ManagementFatemeh Panahi, Iraj MalekmohammadiProblem Statement: Most of the projected increase in global population will take place in third world countries that already suffer from water, food, and health problems. Irrigation in developing countries tends to be stereotyped as equity reducing, in competition with other uses for scarce water resources. Agricultural intensification through the practice of irrigation as a strategy for poverty reduction is … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,032 accessesView PDFCite
Research ArticleOpen accessIn the abstractRe-quantization Codebook Using FingerprintZ. F. Muhsen, M. A. Dababna, A. A. NsourRe-quantization is a key technology for reducing the bit rate of compressed data. The reduction of the bit rate and in certain cases may result in signal quality degradation. Techniques need to be deployed to enhance the signal quality based on optimization techniques. The proposed scheme constructed an optimal re-quantization codebook in an iterative manner for a given original quantization … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,905 accessesView PDFCite
Research ArticleOpen accessIn the abstractSulfur Recovery from Acid Gas Using the Claus Process and High Temperature Air Combustion (HiTAC) TechnologyMohamed Sassi, Ashwani K. GuptaSulfur-bearing compounds are very detrimental to the environment and to industrial process equipment. They are often obtained or formed as a by-product of separation and thermal processing of fuels containing sulfur, such as coal, crude oil and natural gas. The two sulfur compounds, which need special attention, are: hydrogen sulfide (H2S) and sulfur dioxide (SO2). H2S is a highly corrosive … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 17,605 accessesView PDFCite
Research ArticleOpen accessIn the abstractFormation of Optimal Messages Path Delivery Within a Virtual Channel TechnologyH. Al-Bdour, K. KaabnehThis research study deals with the process of reduction and optimization of data transmission delays in mobile Internet networks during mobile subscriber transmission (SsS) to various coverage areas. The methods for information transmission in IP-networks and networks based on virtual channel technology are investigated. Throughout this research, special attention is given to the analysis of existing methods for channel reconfiguration … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,535 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffects of Maize Potato Intercropping and Different Fertilization Methods on Rhizosphere Soil Microorganisms and Yield of PotatoHuanjin Ma, Shengguang Xu et al.A field experiment with three replicates was conducted to explore the effects of maize-potato intercropping and different nitrogen application strategies on rhizosphere soil microorganisms and potato yield. Microbial community analysis was based on relative abundance. Maize-potato intercropping improves land use efficiency, yet how differentiated nitrogen management regulates rhizosphere microecology and potato productivity in this system remains unclear. Clarifying nitrogen-mediated shifts … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 14 Sep 2026 · 790 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSynthesis of Graphene on Conducting Substrate by Electrochemical Deposition MethodMazin Ahmed Ali Moghazi, Sondos Al Shareef, H.Y. Wong, Mukter ZamanInvestigation to optimize the synthesis process of graphene on conducting substrate is essential for many applications. In this investigation suitable approach to extract graphene thin film on a conductive ITO substrate is optimized. This optimization is carried out by electrochemical Reduction of Graphene Oxide (RGO) solution utilizing a repetitive cyclic potential against reference electrode. To do this, Silver chloride reference … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 21 Feb 2017 · 9,578 accessesView PDFCite

However, massive data availability is one of the biggest problems for opinion mining due to accuracy considerations. Selecting high discriminative features from an opinion mining database is still an ongoing research topic. This study presents a two-stage heuristic feature selection method … …Journal of Computer Science, Vol. 17, Issue 3 · 12 Mar 2021 · 6,534 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEvaluation of Fire Effects on Reinforced Concrete Columns Using Finite Element MethodSajjad Sayyar Roudsari, Taher M. Abu-LebdehIn this paper, four different Reinforced Concrete (RC) columns are analyzed with Finite Element (FE) ABAQUS software and validated experimentally. One of the RC columns, the control specimen, is subjected to only compressive force applied at both ends of the column, while the other three models were loaded under both compressive force and fire load. The temperature is applied to … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 20 Jun 2019 · 7,599 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSparse Sliced Inverse Quantile RegressionAli Alkenani, Tahir R. DikheelThe current paper proposes the sliced inverse quantile regression method (SIQR). In addition to the latter this study proposes both the sparse sliced inverse quantile regression method with Lasso (LSIQR) and Adaptive Lasso (ALSIQR) penalties. This article introduces a comprehensive study of SIQR and sparse SIQR.
