Research ArticleOpen accessIn the abstractOrdinal Logistic Regression Model: An Application to Pregnancy OutcomesK. A. Adeleke, A. A. AdepojuProblem statement: This research aimed at modeling a categorical response i.e., pregnancy outcome in terms of some predictors, determines the goodness of fit as well as validity of the assumptions and selecting an appropriate and more parsimonious model thereby proffered useful suggestions and recommendations. Approach: An ordinal logistic regression model was used as a tool to model the three major … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 14,546 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Stock Dependent Economic Order Quantity Model for Perishable Items Under Inflationary ConditionsSingh Sarbjit, Singh Shiv RajProblem statement: In most of the earlier inventory models, effect of inflation has been ignored, which is playing pilot role in present environment. In this article, we have proposed an economic order quantity model for deteriorating items having stock dependent demand (whose demand varies with the stock) under the effect of inflation. Approach: Firstly, problem is framed in the form … …American Journal of Economics and Business Administration, Vol. 2, Issue 3 · 30 Sep 2010 · 7,387 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Thermal Comfort in Respect to Building Height in a High-Density City in the TropicsAnisha Noori Kakon, Mishima Nobuo, Shoichi Kojima, Taguchi YokoProblem statement: The significance of urban design and planning in the tropics lies mostly on its climatic and regional concerns. Among many design parameters, building height is an important parameter which affects thermal climate in the city considerably. This study investigated the effect of building height on outdoor thermal comfort during the daytime in summer in Dhaka, Bangladesh which is … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 3 · 30 Sep 2010 · 8,755 accessesView PDFCite
Research ArticleOpen accessIn the abstractSports: As an Appliance of Incorporation toward Malaysian SocietyAbdul Hafidz Haji Omar, Dayang Hjh. Tiawa Awang Hj. Hamid, Md Rajibul IslamProblem statement: This research investigated the elements of sport that led to social integration in Malaysian society and identified the steps taken to achieve social integration through sports. As a multi racial country, Malaysia consisting of three major races, the Malays, Chinese and Indians were seen practicing the sport cultures that were inherited by their forefathers. History shows that colonization … …Journal of Social Sciences, Vol. 6, Issue 2 · 30 Jun 2010 · 8,642 accessesView PDFCite
Research ArticleOpen accessIn the abstractHomogeneous Bubbles during Jet Impingement QuenchingM. A. Islam, S. F. AhmedProblem statement: Jet impingement quenching has a very effective and large cooling potential and is a very effective means of cooling for many applications. It gives rise to heterogeneous and/or homogeneous nucleation of bubbles, which is yet to be explored. Approach: Analytically investigate the phenomenon that happened during a brief contact of a water jet impinging on a hot surface. … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,162 accessesView PDFCite

Research ArticleOpen accessIn the abstractFactor Analysis, Target Factor Testing and Model Designing of Aromatic Solvent Effect of the Formyl Proton Nuclear Magnetic Resonance Chemical Shift in Para substituted BenzaldehydesGhazwan F. FadhilProblem statement: The variations of formyl proton Chemical Shifts (CS) of p-substituted benzaldehydes in aromatic solvents were investigated. The validity of several physical solvent and empirical solvent scales was examined. Also, to predict dipolarity-polarizability (π*) solvent scale for some aromatic solvents. Model designing was also achieved to rationalize the aromatic solvent effect on the formyl proton CS. Approach: The previously … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,582 accessesView PDFCite

Six hundred and seventy two of twelfth grade and 376 third-year vocational students were selected by multi-stage random sampling techniques. Approach: The instruments used for collecting data were: A scale on self-esteem, a … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 8,103 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 abstractA New Engineering Method for Fuzzy Reliability Analysis of Surge Control in Centrifugal CompressorAhmed Hafaifa, Ferhat Laaouad, Moulod GuemanaProblem statement: The surge phenomenon in the centrifugal compressor, the non-linearities and uncertainties of the compression system make it impossible to use a conventional controller over a wide range of operation. Approach: A new dual fuzzy controller for nonlinear model of compression system was proposed in this study. This fuzzy controller was designed that consisted of active surge control and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,224 accessesView PDFCite
