Research ArticleOpen accessIn the abstractPerformance Evaluation of an Assisting Device for Training "Normal-Like" Sit To Stand MovementPierluigi Rea, Erika Ottaviano, Gianni CastelliThis paper presents a performance evaluation and results on the modelling and simulation of an assisting device to be used as aiding or guiding system for people with reduced mobility. There is a high level of motivation for elderly to perform independently basic Activities of Daily Life (ADL). Therefore, it is of great interest to design and implement reliable assisting … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 26 Jul 2017 · 7,694 accessesView PDFCite
Research ArticleOpen accessIn the abstractAbout the Gear Efficiency to a Simple Planetary TrainRelly Victoria V. Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion T. PetrescuSynthesis of classical planetary mechanisms is usually based on kinematic relations, considering the achieved transmission ratio input-output. The planetary mechanisms are less synthesized based on their mechanical efficiency which is developed during operation, although this criterion is part of the real dynamics of mechanisms and also the most important criterion in terms of performance of a mechanism. Even when the … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 23 Dec 2016 · 8,811 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Adaptive Procedure for the Limit Analysis of FRP Reinforced Masonry Vaults and ApplicationsAndrea Chiozzi, Gabriele Milani, Nicola Grillanda, Antonio TralliThe present paper discusses an adaptive procedure for the kinematic limit analysis of FRP reinforced masonry vaults through applications. The approach relies on a new Genetic Algorithm NURBS-based general framework, which has been recently presented by the authors. The basic idea consists into exploiting the NURBS structure of a CAD geometric 3D model of the selected reinforced masonry vault, in … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 5 Oct 2016 · 8,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractWheeled Mobile Robot Trajectory Tracking using Sliding Mode ControlAzza El-Sayed Bayoumi IbrahimThis paper introduces and discusses a control strategy for nonholonomic wheeled mobile robots. The models of the robots include the kinematic and dynamic equations of motion. Trajectory tracking control problem of parallel wheeled differential drive mobile robot is considered, where the robot should reach the final position by following a referenced trajectory for different initial conditions. A motion control strategy … …Journal of Computer Science, Vol. 12, Issue 1 · 12 Mar 2016 · 9,318 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Anthropomorphic Gripping Manipulator: The Study of Kinematics and Virtual Modeling of GripIvan Vladimirovich Krechetov, Arkady Alekseevich Skvortsov, Pavel Sergeevich Lavrikov, Danil Vladilenovich YatskinThe article is a study into the kinematic scheme of a newly developed anthropomorphic manipulator designed to perform gripping and holding tasks on items from a predefined set. Within the study is the implementation of a mathematical model describing the kinematics of a multilink manipulator using the GraspIt package. The method used in this study allows for the calculation of … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 8 Jan 2016 · 7,677 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Anthropomorphic Gripping Manipulator: The Analysis of Implementation MethodsIvan Vladimirovich Krechetov, Arkady Alekseevich Skvortsov, Pavel Sergeevich LavrikovThe object of the article is the study of implementation methods for the development of hardware-software engineering solutions in the field of the creation of a universal anthropomorphic gripper. Such technical solutions are intended to enable the adaptation and extensive use of advanced robotic systems in the natural environmental conditions formed by people through equipping them with anthropomorphic universal grippers … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 17 Nov 2015 · 6,746 accessesView PDFCite
Research ArticleOpen accessIn the abstractControl of a Step Walking Combined to Arms Swinging for a Three Dimensional Humanoid PrototypeAmira Aloulou, Olfa BoubakerProblem statement: Present researches focus to make humanoid robots more and more autonomous so they can assist human in daily works like taking care of children, aged or disabled persons. In such social activities, the contemporary humanoid robots are expected to have human like morphology and gait. Studies on bipedal locomotion for humanoid robots are then part of the hottest … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinematics Model of Snake Robot Considering Snake ScaleRaisuddin Khan, M. Watanabe, A. A. ShafieProblem statement: In snake robot research, one of the most efficient forms of locomotion is the lateral undulation. However, lateral undulation, also known as serpentine locomotion, is ill-suited for narrow spaces, as the body of the snake must assume a certain amount of curvature to propel forward. Approach: To overcome the inability to adapt to narrow spaces, a novel type … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 8,130 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Enhancement of Weightlifters during Snatch through Reducing Torque on Joints by Particle Swarm OptimizationFirooz Salaami, Nima Jamshidi, Mostafa Rostami, Siamak NajarianIn this research, an athlete's body on sagittal plane in tension phase of snatch weightlifting has been modeled in two dimensions for calculating the generated torques in joints. The error back propagation multi-layer perceptrons has been used for modeling the torque through changing the angular velocity, angular acceleration and absolute angle of each segment. Finally, the torque in joints has … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,101 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Wind Field in Tehran Using Hybrid Diagnostic and Prognostic ModelsM. Shafie-Pour, Y. Rashidi, M. ArdestaniThis article concentrates on Wind Field Simulation in a mega city such as Tehran which is home to nearly 10 million inhabitants. The necessity of having a comprehensive knowledge about the wind field in a certain zone is significant for different reasons; the most important of all would be surveying on the emission and dispersion of pollutants. The wind models … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 6,683 accessesView PDFCite
