Heat acclimation (AC) improves cardiac mechanical and metabolic performance. Using cardiomyocytes and isolated hearts from 30-day and 2-day acclimated rats (AC and AC-2d, 34 degrees C), we characterized cellular contractile mechanisms under normothermic (37 degrees C) and hyperthermic (39-42 degrees C) conditions. To determine contractile responses, Ca2+ transients (Ca2+ T), sarcoplasmic reticu...

The charging infrastructure plays a key role in the healthy and rapid development of the electric vehicle industry. This paper presents an energy management and control system of an electric vehicle charging station. The charging station (CS) is integrated to a grid-connected hybrid power system having a wind turbine maximum power point tracking (MPPT) controlled subsystem, photovoltaic (PV) MP...

Cross-layer design is a promising direction and challenging issue for quality delivery of multimedia over wireless networks. This article proposes a cross-layer design which can substantially enhance the transmission quality of video streaming over 802.11e ad hoc networks. The proposed design consists of two parts: a dispersive video frame importance (DVFI) scheme in the application layer that ...

Abstract Articulating crane (AC), a widely used crane, plays an essential role in various industrial activities. Owing to its strong nonlinearity and uncertainty, tracking control remains challenging, particularly for precise dynamic control. This paper proposes adaptive diffeomorphism-constraint-based (ADCBC) nonlinear AC robustly achieve trajectory while guaranteeing desired performance (DDCP...

conversion systems are based on DFIG technology. Nevertheless, the proposed wind energy conversion system is a good alternate due to its adaptive control with hysteresis controller which can improve the efficiency and reliability. It has capable of controlling DC current according to the wind velocity independently of the DC voltage. Capacitive filters placed on the AC side, which are required ...

in this paper, controlling the gyros with linear plus cubic damping is considered. hence, an adaptive control algorithm is proposed to overcome the uncertainties in model parameters and the chaotic behavior of gyroscopes. it is noted that for general applications dynamic model coefficient of gyros is not precisely determined, on the other hand, with respect to a particular coefficient gyroscope...

accurate and correct performance of controller in cruise control systems is important. hence, in such systems, controller should optimize itself against noise and probable changes in system dynamic. as a matter of fact, in this article three approaches have been conducted to-ward this purpose: mit, direct estimation and indirect estimation. these approaches are used as controllers to track refe...

in this paper, the enhancement of vehicle stability and handling is investigated by control of the active geometry suspension system (ags). this system could be changed through control of suspension mounting point’s position in the perpendicular direction to wishbone therefore the dynamic is alternative and characteristics need to change. for this purpose, suitable controller needs to change mo...
