We propose a new method called Stochastic Model Reference Adaptive Search (SMRAS) for finding a global optimal solution to a stochastic optimization problem in situations where the objective functions cannot be evaluated exactly, but can be estimated with some noise (or uncertainty), e.g., via simulation. SMRAS is a generalization of the recently proposed Model Reference Adaptive Search (MRAS) ...

To reduce pollution and energy consumption, particularly in the automotive industry, saving is main concern, hence, Electric vehicles (EVs) are getting significantly more attention than with internal combustion engines (IC engines). motors used Vehicles must have high efficiency for maximum utilization of from batteries or fuel cells. Also, these be compact, lightweight, less expensive very eas...

Accessing computer resources from off campus has been a continuing problem for both students and faculty, and this problem has been exacerbated by the growth of our graduate program. A multi-layered remote authentication system has been created for use by students and faculty providing the ability to telecommute and gain remote access to these resources. Security concerns have also been address...

By using the direct torque control (DTC), robust response in ac drives can be produced. Ripples of currents, and flux are oberved steady state. space vector modulation (SVM) applied DTC used for a sensorless induction motor (IM) with fuzzy sliding mode speed controller (FSMSC) is studied this paper. This minimize torque, flux, current pulsations To estimate rotor stator model reference adaptive...

The Expectation-Maximization (EM) algorithm is a very popular optimization tool in model-based clustering problems. However, while the algorithm is convenient to implement and numerically very stable, it only produces solutions that are locally optimal. Thus, EM may not achieve the globally optimal solution to clustering problems, which can have a large number of local optima. This paper introd...

The Conventional control approach may not be suitable for non-linear systems and for the systems with considerable parameter variations over a period of time. On the other hand adaptive control techniques proved to be a convenient tool in dealing with the above said systems. The Model Reference Adaptive Systems (MRAS) with performance specifications given in terms of reference model is tried fo...

BACKGROUND Mineralocorticoid receptor antagonists (MRAs) have been associated with improved patient outcomes in patients with heart failure with reduced ejection fraction (HFrEF) but not preserved ejection fraction (HFpEF). We conducted a systematic review and meta-analysis of selective and nonselective MRAs in HFrEF and HFpEF. METHODS We searched Cochrane Central Register of Controlled Trial...
