Research ArticleOpen accessIn the abstractA Non-Linear Absolutely-Stable Explicit Numerical Integration Algorithm for Stiff Initial-Value ProblemsEssam R. El-ZaharThe time-step in integration process has two restrictions. The first one is the time step restriction due to accuracy requirement τac and the second one is the time-step restriction due to stability requirement τst. The most of explicit methods have small stability regions and consequently small τst. It obliges us to solve stiff problems with small step size τst << … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 11 Sep 2013 · 7,565 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Working Integrated Model for the Diffusion of Construction InnovationAhmad Rahman Songip, B.H. Lau, Kamaruzaman Jusoff, Hayati Nor RamliConstruction industry is said to be low in innovation and adoption of innovations is necessary to gain competitive advantage in a liberalized and globalized marketplace. This study investigated the factors that influenced the diffusion of construction innovations and developed an integrated framework to improve the diffusion process. A conceptual model was developed to guide the study and the modification of … …American Journal of Applied Sciences, Vol. 10, Issue 2 · 9 Feb 2013 · 8,045 accessesView PDFCite
Research ArticleOpen accessIn the abstractOrganizational Factors and Innovativeness of Housing DevelopersAhmed Mohammed Kamaruddeen, Nor’ Aini Yusof, Ilias Said, Abd Hamid Kadir PakirIn examining the influence of a firm’s structure and culture on innovativeness among housing developers in Malaysia, we draw a theoretical perspective to develop hypotheses, that propose the structure and culture of the firm as organizational factors which influence innovativeness. We, therefore, examine the direct relationship between independent variables (firm structure and culture) and the dependent variable (firm innovativeness). While … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 12 Dec 2012 · 7,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasures of Explained Variation and the Base-Rate Problem for Logistic RegressionDinesh Sharma, Dan McGee, B.M. Golam KibriaProblem statement: Logistic regression, perhaps the most frequently used regression model after the General Linear Model (GLM), is extensively used in the field of medical science to analyze prognostic factors in studies of dichotomous outcomes. Unlike the GLM, many different proposals have been made to measure the explained variation in logistic regression analysis. One of the limitations of these measures … …Current Research in Biostatistics, Vol. 2, Issue 1 · 25 Feb 2012 · 8,584 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparison of Small-Side Games and Interval Training on Same Selected Physical Fitness Factors in Amateur Soccer PlayersAli Mohammad Safania, Rostam Alizadeh, Maryam NourshahiProblem statement: Soccer is a team sport with an intermittent nature in which the athletes need to improve their physical fitness and skill factors in order to engage in high intensity exercises. The aim of this study was a comparison of small-side game and interval training on some selected physical fitness in amateur soccer players. Approach: Twenty , soccer players … …Journal of Social Sciences, Vol. 7, Issue 3 · 18 Jul 2011 · 8,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Empirical Analysis on Mobile Phone Messaging Satisfaction among Malaysian YouthsVimala Balakrishnan, P.H.P. Yeow, H. S. LooProblem statement: The proliferation of mobile phone use among the youths worldwide has sparked the interest of many researchers, especially those related to the mobile phone adoptions and use. However, there is a lack of study in assessing the impact of the mobile design on its users, especially in relation to the Short Messaging Service application. Due to this, an … …Journal of Social Sciences, Vol. 7, Issue 2 · 21 Mar 2011 · 7,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractLippia graveolens and Carya illinoensis Organic Extracts and there in vitro Effect Against Rhizoctonia Solani KuhnFrancisco Daniel Hernandez-Castillo, Francisco Castillo-Reyes, Gabriel Gallegos-Morales et al.Problem statement: Plant extracts with polyphenolic compounds obtained with different solvents have been evaluated against plant pathogens. However, most of these extract have been obtained using solvents no allowed under an organic production context. Approach: In the present research was to evaluate the inhibitory effect of polyphenolic extracts from L. graveolens and C. illinoensis, obtained with alternative organic solvents (lanolin … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,996 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelationship between Affordances in the Home Environment and Motor Development in Children Age 18-42 MonthsAlireza Haydari, Parviz Askari, Maryam Zarra NezhadProblem statement: Environmental stimulation plays a critical role in optimal human development during the early stages of life and an optimal level (of development) occurs with strong contextual support. It is well accepted among develop mentalists that motor-perceptual-and cognitive development are fundamentally interrelated. This suggests that status of motor development is an important factor in overall child well-being. The objectives … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 9,631 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Strongly Coupled Linear Elliptic Systems with Application to Otolith Membrane DistortionI.K. YoussefProblem Statement: In this research, the author discussed the problems associated with the approximation of the mixed derivative terms appearing in strongly coupled linear elliptic systems by the finite difference method over irregular domains. To avoid the appearance of mixed derivative terms the author introduced a reformulation for the system through introducing a new dependent variable which adds one supplementary … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 6,718 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Gas Velocity and Temperature on Nitric Oxide Conversion in Simulated Catalytic ConverterSathaporn ChuepengProblem statement: Gaseous emissions from gasoline engine such as carbon monoxide, unburned hydrocarbon and nitrogen oxides were usually reduced in three-way catalytic converter simultaneously around theoretical fuel and air combustion. Engine speed and load and other parameters were varied over a wide range of operating conditions, resulting in different exhaust gas composition and condition intake into catalytic converter.
