Case ReportOpen accessEvery word in the titleEvaluation of Seasonal Autoregressive Integrated Moving Average Models for River Flow ForecastingKassahun Birhanu Tadesse, Megersa Olumana Dinka, Tena Alamirew, Semu Ayalew MogesReservoir operation policies cannot be functional in instant decision making without forecasting the future reservoir inflows. For forecasting inflows into reservoirs with only hydrological data is available like Koga irrigation dam, multivariate forecasting models cannot be used to generate accurate river flow information. As a result, an evaluation of univariate Seasonal Autoregressive Integrated Moving Average (SARIMA) models was done for … …American Journal of Environmental Sciences, Vol. 13, Issue 5 · 28 Sep 2017 · 7,891 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleContamination Risk Evaluation of Groundwater in the Canton of Portoviejo-Ecuador, using Susceptibility Index and two Intrinsic Vulnerability ModelsSuhail SharadqahThe present study aims to investigate the applicability of DRASTIC, GOD and SI models in evaluating the groundwater vulnerability and risk of contamination in the Canton of Portoviejo, Ecuador. The groundwater vulnerability to contamination has been evaluated using DRASTIC and GOD models. Both models were able to classify the study area into different sectors of variable vulnerability. The coincidence of … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 11 Feb 2017 · 7,516 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePeriodontal Bone Substitutes Application Techniques and Cost Evaluation: A ReviewJamaluddin Syed, Najmus Sahar, Raffaella Aversa et al.Bioactive Materials have been used since decades but the researches on these materials are still continuing in phase. This material got extra ordinary attention by the scientist and researchers. Bioactive material has ability to bind itself chemically with natural bone tissues. Bioactive materials bring revolution in the field of bone repair and implantology. Bioactive materials have also ability to effect … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 8 Nov 2016 · 8,695 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNutritional Evaluation and Effectiveness of Detoxified Jatropha curcas Kernel Meal in Finishing Pig Diets on Biogas and Methane Production from SlurryBernardo Berenchtein, Adibe Luiz Abdalla, Patricia Pimentel Santos Righetto et al.The purpose of this work was to evaluate Phorbol Ester’s (PE), Total Fenols (TF), Total Tannins (TT), Condensed Tannins (CT), Saponins Content (SPN), amino acids profiles and apparent digestibility of detoxicated Jatropha curcas meal in finishing pigs diets, as well as biogas and methane production by the manure from cross-bred pigs fed this meal. Apparent digestibility coefficients of Dry Matter … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 3 · 30 Aug 2016 · 7,640 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEconomic Evaluation of Streptococcus Pneumoniae Culture MediaVictor Morais, Norma SuárezStreptococcus pneumoniae, a major bacterial pathogen worldwide, requires a complex medium for culture, which complicates harvesting of antigens for vaccine production. Here we present an economic evaluation of factors affecting the production cost of a chemically defined medium for the scale up of fermentation of S. pneumoniae, compared with the most traditional fermentation media. A basic laboratory-scale experiment of 1 … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 27 May 2016 · 8,379 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing the Analytic Hierarchy Process to Establish a Tour Guide Selection and Evaluation ModelHan-Chen Huang, Su-Ling Wu, I-Ying Chang, Pei-Ling LiuThis study aims to examine the criteria for the selection of tour guides, in order to help travel agencies in Taiwan selecting suitable tour guides with a more objective and consistent approach. A tour guide is the life and soul of an organized tour, as well as an important key for the success of the tour. Following the acquisition of … …Journal of Social Sciences, Vol. 11, Issue 4 · 11 Nov 2015 · 7,381 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Evaluation of the Raking Energy in Damping System of Steel Stud Partition WallsSalah Amer, Sameer Hamoush, Taher M. Abu-LebdehNonstructural partition walls are usually specified based on the best practice without any structural design calculations. However, given the likely severe earthquake damage to nonstructural components and the substantial cost of repair to such components, it is imperative that we develop an understanding of the seismic response of the nonstructural partition walls when subjected to earthquake loading conditions. The main … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 6 Nov 2015 · 7,644 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePerformance Evaluation of Search Engines Using Enhanced Vector Space ModelJitendra Nath Singh, Sanjay K. DwivediVector space model allows computing a continuous degree of similarity between queries and retrieved documents and then ranks the documents in increasing order of cosine (similarity) value. It computes cosine or similarity value using their cosine function. The cosine function computes the similarity value by computing the weight of each term in the documents using a weighting scheme but it … …Journal of Computer Science, Vol. 11, Issue 4 · 24 Jul 2015 · 6,761 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleESTIMATION OF AQUIFER PARAMETERS IN ERHO, NIGERIA USING THE COOPER-JACOB EVALUATION METHODOchuko Anomohanran, Ruth E. Iserhien-EmekemeThe aim of this study was to determine the aquifer parameters in Erho, Nigeria. This was carried out by drilling three test wells and three observation wells in the study location. Water was pumped from the test wells at a constant rate while the drawdown in the observation wells was determined as a function of time. The data obtained were … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 6,914 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEVALUATION OF THE ADEQUACY OF THE WIND SPEED EXTRAPOLATION LAWS FOR TWO DIFFERENT ROUGHNESS METEOROLOGICAL SITESDalila Khalfa, Abdelouaheb Benretem, Lazher Herous, Issam MeghlaouiIncreasing knowledge on wind shear models to strengthen their reliability appears as a crucial issue, markedly for energy investors to accurately predict the average wind speed at different turbine hub heights and thus the expected wind energy output. This is particularly helpful during the feasibility study to abate the costs of a wind power project. The extrapolation laws were found … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 1 Feb 2014 · 7,445 accessesView PDFCite
