This paper presents a nonlinear controller based on Sontag’s feedback to render the electromechanical valve actuator (EVA) globally asymptotically stable (GAS). Electromechanical valve actuators have received much attention recently due to their potential for improving the performance of the internal combustion engine. Various control schemes for the EVA have been proposed, however stability is...

Poly(m-chloroaniline) (3clp), polydiphenylamine (dpa), copolymer of diphenylamine and mchloroaniline (3clpdpa), composite of copolymer with TiO2 (3clpdpat), and composite of copolymer with ZnO (3clpdpaz) have been chemically prepared by oxidative polymerization of polymer and copolymer with TiO2, ZnO. These were characterized by FTIR, UV–visible, Fluorescence spectra, Atomic force microscopy an...

Prior to the East Asian financial crisis scholars found the necessity of a true financial performance measure in Malaysia. After more than one decade of the crisis Malaysian firms still stick with the conventional performance measures, which are criticised due to general accepted accounting principles. In this vein, this study aims to study a value based financial performance measure which can ...

Superior encapsulation technology is important for PSCs to prolong their lifetime and realize commercial application. Paraffin/EVA/paraffin composite encapsulated layers were fabricated with the ambient environment under thermal temperature of 80°C, which has advantages simple procedures low cost. paraffin/EVA/paraffin pure EVA maintained 95 45% initial power conversion efficiency (PCE) aged 10...

Ethylene-Vinyl Acetate (EVA) copolymer was synthesized from ethylene and vinyl acetate at high temperatures ultra-high pressures. In this condition, any reactor disturbances, such as process or mechanical faults, may trigger the run-away decomposition reaction. This paper proposes a procedure for constructing conditional health status prediction structure that uses virtual index (HI) to monitor...

Predictability and variability are two measures commonly used in the empirical literature to gauge the quality of earnings and hence, decision usefulness to investors. We adopt both measures to investigate empirically the relative quality of Stern Stewart’s measure of economic value added (EVA) compared to GAAP earnings, residual income, cash flows and other mandated metrics in the US and UK. W...

the performance valuation of the economic enterprise inorder to confidence of limited resources’ optimum allocation is important affaire and as long as it isn’t use of appropriate indicator for performance measurement and stock value of the firm its value not toward reale value and capital doesn’t allocate truly. this subject is more sensitivity in inflation condition. the goal of this research...
