INTRODUCTION This study assesses the changes in human gait in the early postoperative phase of unilateral TKA, by evaluating the variability of free moment. MATERIALS AND METHOD The study group consisted of 10 patients from the Orthopedic Department of the 'Elias' University Hospital in Bucharest who undergone unilateral knee arthroplasty with the same type of posterior cruciate ligament subs...

The purpose of this study was to determine biomechanical factors that may influence golf swing power generation. Three-dimensional kinematics and kinetics were examined in 10 professional and 5 amateur male golfers. Upper-torso rotation, pelvic rotation, X-factor (relative hip-shoulder rotation), O-factor (pelvic obliquity), S-factor (shoulder obliquity), and normalized free moment were assesse...

Two objectives dominate consideration of control moment gyroscopes for spacecraft maneuvers: high torque (equivalentlymomentum) and singularity-free operations.This paper adds to the significant bodyof research toward these two goals using a minimal three-control-moment-gyroscope array to provide significant singularity-free momentum performance increase spherically (in all directions) by modif...

The joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. Generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. Therefore, the bending moment act...

One of the factors that influence dynamic characteristics machining systems is cutting tool. Cutting tools are very diverse, and receptance coupling substructure analysis (RCSA) essential for analyzing each For RCSA, a full matrix equipment essential. In this study, rotational degree-of-freedom was estimated analyzed using translational receptance. Displacement/moment according to distance resp...
