Abstract Multibody musculoskeletal models are important tools to perform kinematic, kinetostatic, and dynamic analyses of the whole human body. In these models, bones regarded as rigid bodies, while different strategies used model structures such muscles ligaments. this context, ligaments often represented using a finite set spring-like elements compute wrench applied (multibundle model). While...

We have compiled a catalog of late-type stars (F5-M) member of representative young disk stellar kinematic groups: the Local Association (Pleiades moving group, 20-150 Myr), Ursa Mayor group (Sirius supercluster, 300 Myr), and Hyades supercluster (600 Myr). Other moving groups as IC 2391 supercluster (35 Myr) and Castor Moving Group (200 Myr) have been also included. Stars have been selected fr...

Existing mapped WENO schemes can hardly prevent spurious oscillations while preserving high resolutions at long output times. We reveal in this paper the essential reason for such phenomena. It is actually caused by that mapping function these not preserve order of nonlinear weights stencils. The may be increased non-smooth stencils and decreased smooth then indicated to require set functions O...

This paper describes a Visual SLAM system developed on a mobile robot in order to support localization services to visually impaired people. The proposed system aims to provide services in small or mid-scale environments such as inside a building or campus of school where conventional positioning data such as GPS, WIFI signals are often not available. Toward this end, we adapt and improve exist...

This contribution addresses forward kinematic solution of modular hybrid manipulator which includes two same Stewart mechanism in serial form known as 2-(6UPS) manipulator. First, using geometrical and vectorial analysis, mathematical model of kinematic analysis for 2-(6UPS) is extracted. As mapping the length of pods to location (orientation and position) of moving mid and upper platforms (for...

PURPOSE To propose and test the feasibility of a novel method for quantifying 3D regional pulmonary kinematics from hyperpolarized helium-3 tagged MRI in human subjects using a tailored image processing pipeline and a recently developed nonrigid registration framework. MATERIALS AND METHODS Following image acquisition, inspiratory and expiratory tagged (3)He magnetic resonance (MR) images wer...

In this study, a method of artificial neural network applied for the solution of inverse kinematics of 2-link serial chain manipulator. The method is multilayer perceptrons neural network has applied. This unsupervised method learns the functional relationship between input (Cartesian) space and output (joint) space based on a localized adaptation of the mapping, by using the manipulator itself...

Interferometric Synthetic Aperture Radar (InSAR) is a rapidly evolving technique. Spectacular results that are obtained in various fields, such as the monitoring of earthquakes, volcanoes, land subsidence and glacier dynamics, as well as in the construction of Digital Elevation Models (DEMs) of the Earth's surface and the classification of different land types, have demonstrated its strength. A...

A visualized dynamic simulation platform of picking robot based on OpenGL and Matlab is established in order to verify the validity of kinematics analysis and visually reflect the motion process. The robot kinematic model is established with D-H method and the forward kinematic solution for the robot is obtained. The inverse kinematic solution is solved by using the simplified inverse transform...
