Research ArticleOpen accessAll words, across the recordA Review of Recent Results on 3D EffectsRelly Victoria V. Petrescu, Florian Ion T. PetrescuThree dimensions or three-dimensional or 3D are expressions that characterize the space around us, as perceived by our vision, in terms of width, height and depth. The term "3D" is also (and improperly) used to refer to the representation in synthetic (digital) images, the relief of stereoscopic images or other images in relief and sometimes even the simple stereophonic effect, … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 28 Dec 2016 · 8,337 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordImproving the Performance of Machine Learning Based Multi Attribute Face Recognition Algorithm Using Wavelet Based Image Decomposition TechniqueS. Sakthivel, M. RajaramProblem statement: Recognizing a face based attributes is an easy task for a human to perform; it is closely automated and requires little mental effort. A computer, on the other hand, has no innate ability to recognize a face or a facial feature and must be programmed with an algorithm to do so. Generally, to recognize a face, different kinds … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,907 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSolving One-Dimensional Cutting Stock Problem with Discrete Demands and Capacitated Planning ObjectiveSirirat Wongprakornkul, Peerayuth CharnsethikulProblem statement: One-dimensional cutting stock problem with discrete demands and capacitated planning objective is an NP hard problem. Approach: The mathematical model with column-generation technique by a branch-and-bound procedure and the heuristic based on the first fit decreasing method are proposed. Then, both approaches were compared and some characteristics were investigated such as upper-bound value, percentage above lower-bound value, computation … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 7,947 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOn Regression Modeling of Human Immunodeficiency Virus PatientsHadeel Salim AL-KutubiProblem statement: The main propose of this study was to evaluate the HIV patients for the period 1990-2008 depend on three variables age, gender and ethnicity. Approach: The data was analyzed using regression and correlation methods to get the mathematical model that explain the relationship and the effect between the age, gender and ethnicity. SSPS program V. 17.0 was used … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 6,413 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComputer Model For Sieves' Vibrations Analysis, Using an Algorithm Based on the False-Position MethodDinu I. Stoicovici, Miorita Ungureanu, Nicu Ungureanu, Mihai BanicaThe analysis of the sieves vibrations in the case of screening civil engineering construction bulk materials is usual made by using some differential equations depending on parameters related to different material and sieves characteristics. One of those parameters is the throwing coefficient -c- that is the ratio between the force capable to throw up the particle from the sieve surface, … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,780 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFlow of Temperature-dependent Viscous Fluid Between Parallel Heated Walls: Exact Analytical Solutions in the Presence of Viscous DissipationK. S. Adegbie, F. I. AlaoWe examine steady incompressible flow of viscous liquids between parallel heated walls of plane Couette device. The temperature of the upper and lower walls of the device are maintained at T = Tb and T = T0 respectively. Of a particular interest are exact analytical solutions of the coupled non-linear differential equations resulting from plane Couette flow obtained for the … …Journal of Mathematics and Statistics, Vol. 3, Issue 1 · 31 Mar 2007 · 7,480 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCRITERIA FOR THE COMPLEXITY OF SUCCESSIVE ASTRONOMICAL PARADIGMSPanagiotis Papaspirou, Kostas Karamanos, Xenophon MoussasWe investigate the complexity of three successive astronomical paradigms in the science of Physics, namely the Ptolemaic paradigm, the Copernican paradigm and the Keplerian paradigm and mention briefly some characteristic facts about the colossal Newtonian paradigm. This complexity can be understood according to five criteria, as proposed by Thomas Kuhn, the father of the epistemological notion of the paradigm, as … …Physics International, Vol. 5, Issue 1 · 28 Mar 2014 · 8,295 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordStabilization of a Nonlinear Delay SystemWalid Arouri, Elyes Maherzi, Mongi Besbes, Houda Ben Attia SethomProblem statement: The analysis and control of delayed systems are becoming more and more research topics in progress. This is mainly due to the fact that the delay is frequently encountered in technological systems. This can affect their significantly operations. Most control command laws are based on current digital computers and delays are intrinsic to the process or in the … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 31 Jan 2012 · 6,844 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTwo Mathematical Modeling Approaches for Integrating Production and Transportation Decisions in the Process IndustryMohamed K. Omar, A. AjithaIn this study we focus on coordination of the production planning of finished products and intermediate products in the process industry. The problem consists of two manufacturing facilities with similar production environment, one producing the intermediates and the other producing end products that are separated by a distance. There is transportation between the facilities. The problem considered has been formulated … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,521 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordReservoir Oscillations with Through FlowA.A. KhanThe two-reservoir problem with through flow is a common feature in wastewater treatment plants. The start of the through flow may cause water surface oscillations in the reservoirs and velocity variations in the connecting pipe during the initial unsteady phase that may adversely affect the operation and under certain conditions may cause overtopping of the upstream reservoir. The classical solution … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,030 accessesView PDFCite
