Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...

The purpose of this study was to quantify the long-term loss of independent finger movements in humans with lesions relatively restricted to motor cortex or corticospinal tract. We questioned whether damage to the motor cortex or corticospinal tract would permanently affect the ability to move each finger to the same degree, or would affect some fingers more than others. People with pure motor ...

Thumb has a critical role in the hand function. It is the most important digit for pinching and grasping. Therefore, thumb amputation demands its replantation or reconstruction to restore the hand functions. A case of hand injury which involved multiple digits along with amputation of thumb is reported. The thumb had amputation level just distal to Metacarpophalangeal joint (MPj) along with amp...

BACKGROUND The theory of homeostatic metaplasticity has significant implications for human motor cortical plasticity and motor learning. Previous work has shown that the extent of recent effector use before exogenously-induced plasticity can affect the direction, magnitude and variability of aftereffects. However, the impact of recent effector use on motor learning and practice-dependent plasti...

BACKGROUND Certain hand activities cause deformation and displacement of the median nerve at the carpal tunnel due to the gliding motion of tendons surrounding it. As smartphone usage escalates, this raises the public's concern whether hand activities while using smartphones can lead to median nerve problems. OBJECTIVE The aims of this study were to 1) develop kinematic graphs and 2) investig...

Introduction: The main objective of all organizations is to improve theefficiency and effectiveness of the personnel’s performance and this partly depends on effective management. Managers are valuable assets and studying their behavior and personality dimensions may provide important guide for effectiveness and efficiency improvement. In this connection, the objective of this research is to de...

We show that in the regime in which feedback control is most effective - when measurements are relatively efficient, and feedback is relatively strong - then, in the absence of any sharp inhomogeneity in the noise, it is always best to measure in a basis that does not commute with the system density matrix than one that does. That is, it is optimal to make measurements that disturb the state on...

A prospective study was undertaken of fifty-one patients who were randomly assigned to treatment with either a long or a short thumb-spica cast for a non-displaced fracture of the carpal scaphoid. The duration of follow-up was at least until union; the average follow-up was twelve months. Twenty-eight fractures were treated with a long thumb-spica cast and twenty-three, with a short thumb-spica...

A case is presented of arteriovenous malformation of the thumb, requiring thumb amputation and free fap coverage for curative treatment. The thumb was reconstructed by pollicization of the index finger as a secondary operation. The patient remains free of recurrence after 2 years and uses the pollicized thumb for daily activities.

Thumb hypoplasia is a component of radial longitudinal deficiency. The severity can range from slightly smaller thumb to complete absence. They are often categorised using Blauth classification recommend appropriate treatment. Type II characterised by the first web-space narrowing, underdeveloped or absence thenar muscles, extrinsic and metacarpophalangeal joint instability. author reviews 7-ye...
