Research ArticleOpen accessIn the abstractEfficient Co-Rotational 3-Node Shell ElementGil Rama, Dragan Marinkovic, Manfred ZehnGeometric nonlinear FE-analysis of thin-walled shell structures, using a co-rotational formulation and the Cell Smoothed Discrete Shear Gap triangular shell element (CS-DSG3) is presented in this study. The CS-DSG3 element formulation uses the Mindlin-Reissner kinematic hypothesis to include transverse shear effects. In order to avoid locking effects Discrete Shear Gap (DSG) method is applied. In addition, cell based smoothing technique … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 17 Jun 2016 · 8,295 accessesView PDF Cite

Research ArticleOpen accessIn the abstractKinematic Comparison of Successful and Unsuccessful Instep Kick in Indoor SoccerNaghme Gheidi, Heydar SadeghiProblem statement: Kicking is one of the most important skills in indoor soccer. Kicking accuracy is an important component of this skill. The instep kick is often used when tacking a penalty kicks, as a combination of increased ball speed and kick accuracy can be maintained. The purpose of this research was to compare selected kinematic parameters of the kicking … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,922 accessesView PDF Cite

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 PDF Cite

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 PDF Cite

Research ArticleOpen accessAll words, across the recordFeature Extraction of Sit-to-Stand Transition Using Vision-Based Pose EstimationAchmad Rizal, Bayu Erfianto, Sugondo Hadiyoso, IstiqomahSit-to-Stand Transition (STS) and vice versa are important indicators of independence and physical health. For normal people, this movement is easy to do but can be difficult for people who have health problems, such as those who have had an injury or stroke. Sit-to-stand assessments can be used to detect spinal disorders. However, spinal kinematic measurements require special instrumentation and … …Journal of Computer Science, Vol. 21, Issue 3 · 21 Feb 2025 · 6,204 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAnalysis and Synthesis of Mechanisms with Bars and Gears Used in Robots and ManipulatorsRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.Bars and gears are used everywhere today, but a wide range of uses is robotics and mechatronics. Since ancient times, automations and mechanization have been used with mechanisms consisting of chains of bars and gears. These were obviously used for the purpose of transmitting the movement and its transformation, that is to say, as a mechanical transmission. Gear and bar … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 20 Dec 2017 · 7,052 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDevelopment 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 PDF Cite
