Physics simulation offers the possibility of truly responsive and realistic animation. Despite wide adoption of physics simulation for the animation of passive phenomena, such as fluids, cloths and rag-doll characters, commercial applications still resort to kinematics-based approaches for the animation of actively controlled characters. However, following a renewed interest in the use of physi...

The locomotion of microorganisms and spermatozoa in complex viscoelastic fluids is critical importance many biological processes such as fertilization, infection, biofilm formation. Depending on their propulsion mechanisms, microswimmers display various responses to a fluid environment: increasing or decreasing swimming speed efficiency, modifying kinematics gaits, experiencing different hydrod...

Background: Lumbar motion analysis is used as a clinical method in the diagnosis and treatment of low back pain (LBP). So far, no studies have shown if manipulating the sacroiliac joint (SIJ) will change spinal kinematics.Objective: The main objectives of this study were to investigate the effects of SIJ manipulation on the lumbar kinematics in subjects with innominate rotation and to compare l...

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...

Complex rotational flows of non-Newtonian fluids are simulated through finite element methods. The predictions have direct relevance to dough kneading, associated with the food industry. The context is taken as two-dimensional and one of stirring material within a cylindrical vessel. Three stirrer shapes are considered, placed in eccentric location with respect to the cylinder centre. The motio...

The numerical simulation of two-dimensional incompressible complex flows of viscoelastic fluids is presented. The context is one, relevant to the food industry, of mixing within a cylindrical vessel, where stirrers are located on the lid of the vessel. Here, the motion is considered as driven by the rotation of the outer vessel wall, with various stirrer locations. With a single stirrer, both a...

background different methods are used for adequate fluid intake assessment, while there is no standard method for adequate fluid intake assessment. objectives the current pilot study aimed to evaluate the amount, type and frequency of fluids consumption to determine the correlation between three- and seven-day records. methods this pilot cross-sectional study was done on 30 adult subjects in ah...

This paper presents the kinematic analysis and the development of a 4-degree-of-freedom serial-parallel mechanism for large commercial vehicle driving simulators. The degrees of freedom are selected according to the target maneuvers and the structure of human motion perception organs. Several kinematic properties of parallel part of the mechanism under study are investigated, including the inve...
