Purpose: This study aimed to investigate excursion changes at the hip, knee, and ankle joints during gait in patients with knee osteoarthritis (KOA) of varying severity. Methods: The method of research was causal-comparative (Ex Post Facto). A Vicon motion analysis system with 4 T-Series cameras was used to measure the kinematics variables. Fifteen normal subjects without KOA and thirty patien...

Solar energetic particles (SEPs) accelerated from shocks driven by coronal mass ejections (CMEs) are one of the major causes geomagnetic storms on Earth. Therefore, it is necessary to predict occurrence and intensity such disturbances. For this purpose we analyzed in detail 38 non-interacting halo partial CMEs, as seen Heliospheric Observatory/Large Angle Spectrometric Coronagraph, generating S...

A robotic device is proposed by means of which the mastication process could be reproduced in a mechanically controllable way whilst the masticatory efficiency and/or food dynamics are assessed quantitatively. A robotic model of the mastication system is developed according to biomechanical findings about the jaw structure and muscles of mastication, where each of the major muscles are, tempora...

In this paper, a novel four-degree-of-freedom (4-DOF) hybrid parallel platform manipulator is presented. The movable platform of the parallel manipulator can translate along two directions and rotate around two axes respectively. The kinematics model is formulated, which describes the inverse kinematic transformation and forward kinematic transformation. A 5-axis parallel machine tool based on ...

A kinematic mapping of planar displacements is used to derive generalized constraint equations having the form of ruled quadric surfaces in the image space. The forward kinematic problem for all three legged, three degree of freedom planar parallel manipulators thus reduces to determining the points of intersection of three of these constraint surfaces, one corresponding to each leg. The invers...

We present the current status of performance studies Λ hyperon directed flow measurement with CBM experiment at future FAIR facility in Darmstadt. Kalman Filter mathematics is used to reconstruct Λ→pπ− weak decay kinematics, while Particle Finder Simple package optimize criteria for candidate selection. Directed hyperons studied as a function rapidity, transverse momentum and collision centrali...

We review both the kinematics and dynamics of non-lorentzian theories their associated geometries. First, we introduce kinematical spacetimes symmetry algebras. Next, construct actions describing particle in some these spaces using method nonlinear realisations. explain relation with coadjoint orbit method. continue discussing three types gravity theories: Galilei gravity, Newton-Cartan Carroll...

This work reports the design, construction and deployment of a mechatronic system, which, combined with computer vision module, provides students teachers tool to experience concepts kinematics particle throughout usage robot, known as Cinebot, which can be controlled from any smart device endowed stable internet connection. The methodology used for envisioning developing system was engineering...

This paper deals with the design and analysis of a two-translation and one-rotation (2T1R) mechanism for a novel cooking robot. Firstly the motions involved in stir-fry, the most representative operation in the cooking processes used in Chinese cuisine, are analyzed in details. Then the featured motions are decomposed into four main movements that are used as a design base for a wok motion mech...

The traditional methods for representing forward kinematics of manipulators have been the homogeneous matrix in line with the D-H algorithm. In this paper a new method known as quaternion algebra is described and it is used for three dimensional representation and orientation in robot kinematics. This method is compared with homogeneous transform in terms of easiness of representation, computat...
