Research ArticleOpen accessIn the abstractA Study of the Effect of Infilled Brick Walls on Behavior of Eccentrically Braced Frames Using Explicit Finite Elements MethodAmir Saedi Daryan, Masood Ziaei, Ali Golafshar et al.Problem statement: Eccentrically Braced Frames (EBFs) are usually infilled by masonry walls, but in common design, the stiffness and lateral resistance of these walls is ignored. Considering the results of carried out tests and studies, it seems that infilled masonry walls have a significant influence on the stiffness and the strength of EBFs. Since experimental test of total frame with … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,196 accessesView PDFCite
Research ArticleOpen accessIn the abstractReduced Order Models of a Current Source Inverter Induction Motor DriveIbrahim K. Al-AbbasProblem Statement: The current source inverter induction motor (CSI-IM) drive was widely used in various industries. The main disadvantage of this drive was nonlinearity and complexity. This work was done to develop a simple drive systems models. Approach: The MATLAB/SIMULINK software was used for system modeling. Three reduced models were developed by choosing specific frame, neglecting stator transients and ignoring … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,869 accessesView PDFCite
Research ArticleOpen accessIn the abstractPitch Angle Control of Variable Speed Wind TurbineYousif El-TousThe aim of this study is to design a simple controller to maximize the extracted energy of wind turbines. In this study the pitch angle control of variable speed wind turbine is investigated. In particular, it concentrates on the extraction of maximum available energy, reduction of torque and output power variations, which gives stresses in the gearbox and mechanical structure. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 8,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Implementation of an Adaptive Control for a RobotIraj Hassanzadeh, Abbas Harifi, Farid ArvaniThis research investigates the performance of an adaptive controller for five-bar linkage robot. The proposed controller was entirely independent on the physical specifications of the robot. The controller was examined as the dynamics of the mechanical system varies for various environment conditions, which make it an ambiguous system. In this study, the introduced controller was designed based on the governing … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 6,647 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Prototype Automated Sorting System for Plastic RecyclingD. A. Wahab, A. Hussain, E. Scavino et al.Automated sorting for plastic recyclables has been seen as the way forward in the plastic recycling industry. Automated sorting provides significant improvements in terms of efficiency and consistency in the sorting process. In the case of macro sorting, which is the most common type of automated sorting, efficiency is determined by the mechanical details of the material handling system as … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 8,829 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Analysis of Pressure Pulses in the Jerk Fuel Injection SystemsR. A. Baker, T. FirozComputer software has been developed and described in the present study of thorough parametric analysis and design of a mechanical diesel fuel injection system. The method is based on the numerical solution of one dimensional, unsteady, incompressible flow equations through the fuel pipe along with appropriate initial condition, pump end boundary condition and nozzle end boundary condition. Method of characteristics … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamics at Classical DistributionRelly Victoria Virgil PetrescuClassical distribution is the most used in rigid memory mechanisms adapted to four-stroke internal combustion engines such as Otto or diesel, as it was designed by Otto more than 150 years ago, without essential changes from its conception and up today. Since it was not yet possible to introduce the electric car to the industrial scale and today we have … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 26 Apr 2019 · 6,400 accessesView PDFCite
Review ArticleOpen accessIn the abstractDynamic Models of Rigid Memory MechanismsFlorian Ion Tiberiu PetrescuRigid memory mechanisms have played an important role in the history of mankind, contributing greatly to the industrial, economic, social changes in society, thus leading to a real evolution of mankind. Used in automated tissue wars, in cars as distribution mechanisms, automated machines, mechanical transmissions, robots and mechatronics, precision devices and medical devices, these mechanisms have been real support for … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 7,264 accessesView PDFCite
Review ArticleOpen accessIn the abstractRomanian Engineering "On the Wings of the Wind"Relly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuThe presented study proposes a commemoration of the main artisans of the Romanian and world aviation, from its beginnings to the day. Very briefly are brought to the forefront, the main inventors of flying machines and equipment that have lived here in the Romanian territory and have contributed substantially to the development of any type of flight. We will talk … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 18 Jan 2018 · 9,414 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegradation of Power Generation Performance due to Effects of Various Ice Shapes and Accretions on Wind Turbine BladesAditya Bagade, Changki Mo, Abdelhamid MazherIn today’s world, green energy has become a key initiative as an alternative energy resource. Wind turbines are widely used to harvest wind energy in seasonal and cold environments. Although efficient, cold weather conditions negatively affects wind turbine operations due to ice formation. Damage from icing is seen on blade-tips when super-cooled water droplets that form in colder environments rapidly … …Energy Research Journal, Vol. 6, Issue 2 · 11 Sep 2015 · 7,818 accessesView PDFCite
