The objectives of this research were: 1) to determine how the use of upper extremities to assist during a chair rise task affects lower extremity loading; 2) to examine how task difficulty affects performance when weakness is present; and 3) to compare the compensation strategies utilized by individuals with chronic weakness to those used by patients with acute weakness. Twelve polio survivors ...

During its melt cycle, an arc furnace causes disturbances of the electrical supply. Existing measurement techniques for this application lead to corrective rather than predictive compensation. The use of neural networks to control the compensation is being considered, in particular reinforcement learning strategies which require no pre-training and which can adapt to a dynamically changing envi...

BACKGROUND California Workers' Compensation (WC) system costs are under review. With recently approved California State Assembly Bill (AB) 749 and Senate Bill (SB) 228, an assessment of proposed pharmaceutical cost savings is needed. METHODS A large workers' compensation database provided by the California Workers' Compensation Institute (CWCI) and Medi-Cal pharmacy costs obtained from the St...

Using data from 200 employees of FMCG companies in Multan, this study aims to analyze the effect Employee Empowerment and Compensation on Job Performance while moderating role Accountability. The partial least square method is used estimate results. results PLS-SEM reveal that Empowerment, Compensation, Accountability are all positively significantly related Performance. was found partially mod...

Compensation is a kind of pro-social behavior that can restore a social relationship jeopardized by interpersonal transgression. The effectiveness of a certain compensation strategy (e.g., repaying money, sharing loss, etc.) may vary as a function of the social norm/relationship. Previous studies have shown that two types of norms (or relationships), monetary/exchange and social/communal, diffe...

Three different conventional control strategies for extracting reference currents for shunt active power filters have been evaluated and their performance has been compared under various non linear loads. Comparison of the compensation ability of different control strategies based on THD and speed will be done and suggestions will be given for the selection of strategy to be used under differen...

This paper describes friction compensation based control of an industrial pneumatic actuator used for the variable geometry turbocharger (VGT). Adaptive LuGre model for friction has been used in this work. Friction force that is responsible for hysteresis and hunting phenomenon in the position control is compensated with two different control strategies designed to improve low velocity position...

This paper proposed an accurate analytical method to calculate the current harmonic components of uncontrolled rectifiers. These analyses are greatly simplified through superposition method. All the calculations are purely algebraic, with high accuracy. The validity of the proposed method is demonstrated by comparison with the results of time-domain simulation. Therefore, choice of power compen...
