BACKGROUND Accurate prediction of in vivo muscle forces is essential for relevant analyses of musculoskeletal biomechanics. The purpose of this study was to evaluate three methods for predicting muscle forces of the shoulder by comparing calculated muscle parameters, which relate electromyographic activity to muscle forces. METHODS Thirteen subjects performed sub-maximal, isometric contractio...

This paper describes a set of methods that can be used to integrate real-time external vision sensing with internal force and position sensing to estimate contact forces by the fingers of a hand. Estimating these forces and contacts is essential to performing dextrous manipulation tasks. Most robotic hands are either sensorless or lack the ability to accurately and robustly report position and ...

The classical active contour model has two basic internal forces: tension and curvature. These forces are included to provide cohension, equal control point spacing, and locally smooth shape. These classical internal forces have undesirable attributes that are in conflict with these original desired characteristics. Tension evenly spaces the control points, but also causes the models to collaps...

This paper presents the results of evaluations on redistribution internal forces from span to support area using nonlinear finite element calculations. The motivation is internalization bridges, particularly reconstruction single-span beams arranged in a row continuous beam system. When integralizing bridge, it can be assumed that existing bridge designed according standards, which are no longe...
