Research ArticleOpen accessEvery word in the titleGrowth Performance and Biomass Accumulation of a Khaya ivorensis Plantation in three Soil Series of UltisolsYetti Heryati, Debora Belawan, Arifin Abdu et al.Abstract: Problem statement: There was no information about the relationship between growth parameters, such as diameter and height and tree component biomass of Khaya ivorensis plantations with different soil types. The objectives of this study were, first, to determine and compare the growth of K. ivorensis in three different (Padang Besar, Durian and Rengam) soil series of Ultisols and, second, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 10,175 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThree-Dimension Coronary Artery Tree Curvature ConfirmationHassan H. Khalil, Rahmita O.K. Rahmat, D. M. Zamrin et al.Problem statement: Three-Dimension (3D) reconstruction is one of the vital and robust tools that provide aid in many fields, especially medicine. This article is about 3D shape similarity and it presents a comparison approach between principal curvature methods of 3D output. Our approach follows the concept of using the gray scale value as the z dimension and the other approach … …Journal of Computer Science, Vol. 6, Issue 12 · 30 Nov 2010 · 7,771 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThree Dimension Reconstruction of Coronary Artery Tree Using Single-View CineangiogramHassan H. Khalil, Rahmita O.K. Rahmat, D. M. Zamrin et al.Problem statement: Whereas most of the conventional techniques propose using multiview cineangiograms to reconstruct 3D objects this article proposes to integrate a Three Dimension (3D) model of the coronary artery tree using a standard single-view cineangiogram. Splitting the cineangiograms into non-sequenced and different angle views is how the data is supplied in this method. Each single view can be used … …Journal of Computer Science, Vol. 6, Issue 12 · 22 Nov 2010 · 8,031 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Size of Heated Obstruction within Room on Three Dimensional Air Flow CharacteristicsAbduljabbar Muttair Ahmed, Mukhtar Ahmad, Abdur RahimProblem statement: This study reported a numerical investigation of three-dimensional turbulent buoyant recirculating flow within a room with heated obstruction. Approach: The study involved the solution of partial differential equations for the conservation of mass, momentum, energy, concentration, turbulent energy and its dissipation rate. These equations were solved together with algebraic expressions for the turbulent viscosity and the heat diffusivity, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 6,942 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMeasure for No Three-Factor Interaction Model in Three-Way Contingency TablesKouji Yamamoto, Kyoji Hori, Sadao TomizawaProblem statement: For 2×2×K contingency tables, the measure is considered to represent the degree of departure from a log-linear model of No Three-Factor Interaction (NOTFI). We are interested in considering a similar measure for general I×J×K contingency tables. Approach: The present study proposed a measure to represent the degree of departure from the NOTFI model for I×J×K contingency tables. Also … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 7,786 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudy on the Effect of Allylisothiocyanate Formulations on Three Lepidopterous Insect Larvae, the Diamond Back Moth, Plutella xylostella (L.), the Small Cabbage White Butterfly, Pieris rapae (L.) and Tobacco Cut Worm, Spodoptera litura FabrE. M. Eltayeb, Guo-An Zhang, Jiu-Gao Xie, Feng-Yu MiProblem statement: The toxicity of seven of Allylisothiocyanate (AITC) formulations, AITC pure and in mixture with cypermethrin and chlorpyrifos, was evaluated using spray application and fumigation method against the diamondback moth, Plutella xylostella (L.), the small cabbage white butterfly, Pieris rapae (L.) and the tobacco cut worm, Spodoptera litura Fabr. Approach: Response varied according to insect species, specific formulation and … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 6,993 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCost Analysis of Two-Dissimilar-Unit Cold Standby System with three States and Preventive Maintenance Using Linear First Order Differential EquationsM. Y. HaggagProblem statement: Several researchers have studied the reliability behavior of a three state systems, but no attention was paid to the reliability evaluation due to preventive maintenance. The better maintenance of the system originates better reliability. Also, standby support increases the reliability of the system. Approach: Determine the efficacy of preventive maintenance on the reliability and performance of the system. … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 6,881 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleA New Three-Term Preconditioned Gradient memory Algorithm for Nonlinear Optimization ProblemsAbbas Y. AL-Bayati, Ivan S. LatifIn the present study, we proposed a three-term of preconditioned gradient memory algorithms to solve a nonlinear optimization problem. The new algorithm subsumes some other families of nonlinear preconditioned gradient memory algorithms as its subfamilies with Powell's Restart Criterion and inexact Armijo line searches. Numerical experiments on twenty one well-known test functions with various dimensions generally encouraged and showed that … …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 6,783 accessesView PDFCite
