Research ArticleOpen accessPhrase in the titleAn Analytical Method for Determining Forces within a TriadFlorian Ion Tiberiu Petrescu, Taher M. Abu-Lebdeh, Antonio ApicellaThe paper presents an original analytical method used in determining the forces within a triad structural group. If the triad is in the mechanical equivalent of the transistor in electronics, representing a very useful structural group, while the transistor is no longer a puzzlement from a long time period, the triad was not too studied analytically, generally being approached by … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 26 May 2018 · 7,868 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAdvantage of Classical Approximate Analytical Methods for Studying Rydberg States Over the Quantum CounterpartsEugene OksIn studies of atomic and molecular systems, approximate analytical methods play a significant role. This is because they can be used for benchmarking the results of numerical methods. Besides they offer a physical insight into the phenomena under consideration an insight impossible to achieve by numerical methods. Many approximate analytical methods were developed in such a way that each method … …Physics International, Vol. 14, Issue 1 · 2 Jul 2024 · 8,007 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison of Maximum Gear-Tooth Operating Bending Stresses Derived from Niemann's Analytical Procedure and the Finite Element MethodAndonios D. Tsolakis, Konstandinos G. RaptisProblem statement: Main purpose of this study was to investigation toothed gear loading problems using the Finite Element Method. Approach: We used Niemann’s equations to compare maximum bending stress which was developed at critical gear-tooth flank point during gear meshing, applied for three distinct spur-gear sizes, each having different teeth number, module and power rating. Results: The results emerging after … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 18 Aug 2011 · 7,695 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalytical Method Validation of Vilazodone with Spectrofluorimetric Detection in Rabbit PlasmaIrene Sartini, Marco Salvadori, Beata Łebkowska-Wieruszewska et al.Vilazodone (VLZ) is an antidepressant agent approved in 2011 by Food and Drug Administration (FDA) for the treatment of major depressive syndromes. Its chemical structure derives from trazodone which is used as an off-label drug for dogs and cats in order to induce sedation and reduce anxiety, behavioural and pre-and post-operative stress. VLZ could be a potentially useful compound in … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 1 · 2 Apr 2019 · 7,740 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Comparison of Explicit Semi-Analytical Numerical Integration Methods for Solving Stiff ODE SystemsE.R. El-Zahar, H.M. Habib, M.M. Rashidi, I.M. El-DesokyIn this study, a comparison among three semi-analytical numerical integration algorithms for solving stiff ODE systems is presented. The algorithms are based on Differential Transform Method (DTM) which are Multiple-Step DTM (MsDTM), Enhanced MsDTM (E-MsDTM) and MsDTM with Padé approximants (MsDTM-P). These methods can be classified as explicit one step semi-analytical numerical integration methods. The error and stability analysis of … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 26 Jun 2015 · 6,955 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalytical Investigation of Hyperbolic Equations via He's MethodsD.D. Ganji, M. Amini, A. KolahdoozPerturbation methods depend on a small parameter which is difficult to be found for real-life nonlinear problems. To overcome this shortcoming, two new but powerful analytical methods were introduced to solve nonlinear heat transfer problems in this Letter, one is He's Variational Iteration Method (VIM) and the other is the Homotopy-Perturbation Method (HPM). Nonlinear hyperbolic equations were used as examples … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,115 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Review on Supercritical Fluid Extraction as New Analytical MethodK. A. Abbas, A. Mohamed, A. S. Abdulamir, H. A. AbasThis review study summarized the Supercritical Fluid Extraction (SFE) as new analytical method. The advantage and disadvantage of CO2 (SC-CO2 )as well as special applications of SFE in food processing such as removal of fat from food, enrichment of vitamin E from natural sources, removal of alcohol from wine and beer, encapsulation of liquids for engineering solid products and extraction … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 10,498 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApproximate Analytical Solutions For Time-Dependent Emden-Fowler-Type Equations By Variational Iteration MethodKhaled BatihaThe main objective of the current study was to solve the time-dependent Emden-Fowler-type equation with singular behavior. The technique used here was called the variational iteration method (VIM). The advantage of this work is twofold. Firstly, the VIM reduces the computational work. Secondly, in comparison with existing techniques, the VIM is an improvement with regard to its accuracy and rapid … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 6,591 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Evaluation of the Groundwater Influence on the Stress and Strain Behavior around a Tunnel by Analytical MethodsPierpaolo OresteThe presence of an aquifer in the soil causes a change in a relevant way of the stability conditions of a tunnel. The flow of water in the pores, in fact, modifies the stress and strain state of the soil and causes an increase in the thickness of the plastic zone. As a result the loads transmitted on the lining … …American Journal of Applied Sciences, Vol. 12, Issue 10 · 30 Oct 2015 · 6,459 accessesView PDFCite
Research ArticleOpen accessIn the keywordsKinematics of the Basic Mechatronic Module 3R of an Anthropomorphic RobotFlorian Ion Tiberiu PetrescuThe kinematics of the basic mechatronic module 3R of an anthropomorphic robot will be presented in this study, through an original geometric-analytical method, developed by the author. The advantages of the proposed new method are a great simplicity of calculations and calculation relations, intertwined with very high precision. The method is a strong one from a physical-mathematical point of view. … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 8 Feb 2021 · 7,454 accessesView PDFCite
