Research ArticleOpen accessAll words, across the recordA Brief Introduction to the Bird Strike Numerical SimulationAniello Riccio, Roberta Cristiano, Salvatore SaputoBird impacts can be extremely critical events for the air transport safety. Since aircraft structures have become more and more complex components, the numerical prediction of the damage onset and evolution induced by a bird impact has become a very challenging task. The aim of this work is to provide a brief overview of the numerical techniques adopted for the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 4 Nov 2016 · 8,667 accessesView PDFCite

RoyProblem statement: In this study linear stability of a class of three neuron cellular network with transmission delay had been studied. Approach: The model for the problem was first presented. The problem is then formulated analytically and numerical simulations pertaining to the model are carried out. Results: A necessary and sufficient condition for asymptotic stability of trivial steady state in … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 7,598 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFinite Element Analysis of Frictional Contact Problem During the Process of Metal WorkingNicolae PopThe quasistatic contact problem with dry friction, contributes to the achievement of a numerical model for the simultaneity of different kinds of viscoplastic, incompressible materials forming. Starting from a variational formulation of the problem, which extends the static case, a perturbed Lagrangean, discrete formulation within the framework of finite element method is obtained. On the contact boundary we have used … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 7,293 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAnalysis of Non-Equilibrium Phase Change in Transfers at Low Water Content by Considering the Film FlowMarcel Bawindsom Kébré, François Ouédraogo, Bétaboalé Naon et al.In this study, we analyze the effect of non-equilibrium phase change on transfer at low water content in a sandy soil by considering the contribution of film flow in the motion of liquid water. Indeed, most of the non-equilibrium study methods use for hydraulic conductivity, the van Genuchten-Mualem (VGM) capillary model which does not consider the film flow occurred at … …American Journal of Environmental Sciences, Vol. 17, Issue 1 · 1 Jun 2021 · 6,395 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Drives and Control Integrated Time-Domain Dynamic Analysis and Modeling Approach Applied To Ultra-Precision Machine ToolsTianjian Li, Shijin Chen, Haijun Zhang, Kai ChengProblem statement: Machines dynamic performance depends not only upon the mechanical structure and components but also the drives and control system. However, the design of the machines is still at the nascent stage by working on an individual machine basis, hence lacks generic scientific approach and design guideline. Approach: Using computer models integrated drives and control system to predict the … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 29 Jul 2011 · 8,088 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordTime-Temperature Dependency of Laminated Glass Subjected to Blast Load – A Numerical StudyMatthias FörchThe behavior of laminated glass has strong time-temperature dependency. Viscoelastic material models are often employed to define mechanical properties of Polyvinyl Butyral (PVB), the most common interlayer for structural glass applications. However, it is an apparent notion to simplify the high complexity of such material models, as only specific software is capable of considering this behavior. Most studies in blast … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 18 Mar 2020 · 7,676 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordImage Analysis with Legendre Moment DescriptorsAmy Chiang, Simon LiaoIn this research, a numerical integration method is proposed to improve the computational accuracy of Legendre moments. To clarify the improved computation scheme, image reconstructions from higher order of Legendre moments, up to 240, are conducted. With the more accurately generated moments, the distributions of image information in a finite set of Legendre moments are investigated. We have concluded that … …Journal of Computer Science, Vol. 11, Issue 1 · 15 Sep 2014 · 7,360 accessesView PDFCite
