Research ArticleOpen accessPhrase in the titleEffect of Object Size and Location on Contact Forces and Grasping Stability for an Underactuated Robotic ManipulatorSomer Matti Nacy, Ahmed Abdulsalam NayifThis paper comprises a study of the grasping stability for an underactuated robotic manipulator under the condition of varying the position of different sizes cylindrical grasped objects. Grasping forces were calculated both theoretically and Via a CAD model for a 3-DOF underactuated robotic manipulator. The experimental part comprises the fabrication of the manipulator and performing the required tests on this … …Journal of Mechatronics and Robotics, Vol. 2, Issue 1 · 24 May 2018 · 7,038 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Trilobatin on Bovine Serum Albumin: Interaction Mechanism and Molecular DockingYuhan Zhai, Yuqing Zhang, Yaping Li et al.Understanding the transport and distribution of small molecules in vivo is aided by studying their interactions with proteins. As a natural sweetener, trilobatin possesses several biological activities. However, uncertainty surrounds the trilobatin and Bovine Serum Albumin (BSA) interaction mechanism. In this study, the binding types, number of binding sites and binding constants of trilobatin interaction with BSA were studied by … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 29 Mar 2024 · 4,843 accessesView PDFCite
Review ArticleOpen accessIn the abstractMechatronic Systems to the Braking MechanismsRelly Victoria Virgil PetrescuWith the evolution of technology, the construction and geometry of the piston, together with the materials from which it is made, as well as the related manufacturing technologies, have been continuously improved. Thus, modern engines have become less polluting, working at higher temperatures and pressures. Body aerodynamics have been improved, leading to lower resistance forces from the air. Also, the … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 18 Aug 2020 · 6,954 accessesView PDFCite
Research ArticleOpen accessIn the abstractTribological Performance of Materials Under Bio-Three Body AbrasionJasem G. Alotaibi, Ako K. Omer, Nbhan D Salih, Belal F. YousifThis study aims to investigate the effects of seed grinding process on the tribological characteristics of components in agricultural machines. The objective is to conduct the the effect of third body presence such as seeds on the tribological behavior of agriculture machines and evaluate the fracture mechanism of the seeds under three body abrasion loading conditions. The work consists of … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 14 Jul 2020 · 7,178 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamics of Buses - Part IIIRelly Victoria Virgil Petrescu, Raffaella Aversa, Gheorghe Frăţilă et al.Dynamics, or dynamic processes, is the part of mechanics dealing with the study of processes trying to describe as real as possible the movement of a body, element, mechanism, car, etc., also taking into account the action of the forces on the respective system with their influence on the actual movement of system. The present paper aims to present the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 20 Apr 2018 · 8,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractGears-Part IIRelly Victoria V. Petrescu, Raffaella Aversa, Bilal Akash et al.The paper presents an original method for the determination of the yield of the gearbox, gears forces, gearbox and power. It analyzes the influence of certain parameters which affects the efficiency of the gearbox. Also an original method for the determination of the yield of the drive shafts oriented on the basis of the ratio of contact is presented the … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 10 May 2017 · 7,340 accessesView PDFCite
Research ArticleOpen accessIn the abstractSensorization of Robotic Hand Using Optical Three-Axis Tactile Sensor: Evaluation with Grasping and Twisting MotionsHanafiah Yussof, Jiro Wada, Masahiro OhkaProblem statement: Sensitization of robot hand is still remaining as crucial issue since most of robot hand systems nowadays are only capable to grasp a predefined specific object. It is still difficult for robot hand system to realize human-like tactile sensation. Some common problems in robot hand system are low accuracy sensing device, sensors are not robust enough for long … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,846 accessesView PDFCite
Research ArticleOpen accessIn the abstractRehabilitation of a Human Arm Supported by a Robotic Manipulator: A Position/Force Cooperative ControlHaifa Mehdi, Olfa BoubakerProblem statement: The assistance of person with limited ability of arm movement is necessary for rehabilitation reasons. This aid is required not only to cover the human performances of the arm in motion and force but also to have a strictly stable dynamics. In this study, we proposed a cooperative system between a disabled arm and a robotic manipulator to … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,456 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing a Truss-Inspired Model with the Uniform Strength Optimization Theory to Predict Spongy Bone Geometry in Proximal FemurHamed Pishdast, Farzam Farahmand, Gholamreza RouhiThis paper presents a new naïve approach for simulating bone remodeling process. It is based on the uniform strength theory of optimization and employs a truss-like model for bone. The truss was subjected to external loads including 5 point loads simulating the hip joint contact forces and 3 muscular forces at the attachment sites of the muscles to the bone … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,174 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Dynamic Model for GearsAversa Raffaella, Relly Victoria V. Petrescu, Antonio Apicella, Florian Ion T. PetrescuNearly all models studying the dynamic of gearing with parallel axes are based on classical mechanical models and known which are studying the spinning vibration of shafts gears and determine their own beats and strains of shafts spinning. These classical dynamic models are very useful, but they didn't take in consideration the dynamic events formed between the two teeth in … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 10 May 2017 · 7,644 accessesView PDFCite
