Are fingertip forces produced by subject-independent patterns of muscle excitation? If so, understanding the mechanical basis underlying these muscle coordination strategies would greatly assist surgeons in evaluating options for restoring grasping. With the finger in neutral ad- abduction and flexed 45 degrees at the MCP and PIP, and 10 degrees at DIP joints, eight subjects attempted to produc...

Nowadays, due to the escalation in construction of high-rise structures, the need for selecting a proper resistant structural system against earthquake and wind has increased significantly. These systems should show an optimized use of materials and should be presented as a hard and efficient structure. A good example of a high efficient system in high-rise buildings can be indicated is, the tu...

Adhesion level for the proper running of rail wheelset on track has remained a significant problem for researchers in detecting slippage to avoid accidents. In this paper, the slippage of rail wheels has been observed applying forward and lateral motions to slip velocity and torsion motion. The longitudinal and lateral forces behavior is watched with respect to traction force to note correlatio...

Abstract: The governing equations of motion for a drill string considering coupling between axial, lateral and torsional vibrations are obtained using a Lagrangian approach. The result leads to a set of non-linear equations with time varying coefficients. A fully coupled model for axial, lateral, and torsional vibrations of drill strings is presented. The bit/formation interactions are assumed ...

STUDY DESIGN Single-cohort descriptive and correlational study. OBJECTIVES To investigate the relationships between tendon pathology, biomechanical measures, and self-reported pain and function in individuals with chronic lateral epicondylosis. BACKGROUND Lateral epicondylosis has a multifactorial etiology and its pathophysiology is not well understood. Consequently, treatment remains chall...

1. Pressures on the right and left sides of the tails of swimming bluefish were measured and found to have a range of +5*9 to —5-9 cm H20. The pressures were resolved into their forward and lateral vectorial components of force to allow calculation of forward and lateral force and power at speeds ranging from 0-26 to 0-87 m/s. 2. The peak to peak changes in force of acceleration of the body, me...

The tyre lateral force control is crucial to vehicle stability. Vehicle side slip and out of can be prevented effectively by observing accurately the force. Thus, a novel quasi-sliding mode observer (QSMO) proposed. algorithm adopts longitudinal error as feedback considering parameter uncertainties without complex model. First, on-line verification was carried dSPACE for using experimental data...

Supramolecular complexes, such as chaperonins, are suitable samples for atomic force microscope structural studies because they have a very well defined shape. High-resolution images can be made using tapping mode in liquid under native conditions. Details about the two-dimensional structures formed onto the surface upon adsorption and of the single protein can be observed. Dissection of the up...
