a fuzzy observer based scheme for synchronizing two hyperchaoticoscillators via a scalar transmitted signal for cryptographic application isproposed. the takagi-sugeno fuzzy model exactly represents chaotic systems.based on the general fuzzy model, the fuzzy observer of a chaotic system isdesigned on the basis of the n-shift multiple state based key encryption algorithm.the scalar transmitted s...

Steering assist system controls the force transfer behavior of the steering system and improves the steering probability of the vehicle. Moreover, it is an interface between the diver and vehicle. Fault detection in electrical assisted steering systems is a challenging problem due to frequently use of these systems. This paper addresses the fault detection and reconstruction in automotive elect...

GivenK > 0 and a positive integerM, the function△K,M (t) = Kmax(1− |t| M , 0) represents an isosceles triangle on the real line R having height K and base 2M. For a given K and M, a constant amplitude sequence is constructed on the integers Z having autocorrelation △K,M restricted to Z. With this setup, a large class of bounded sequences z is shown to exist, where the autocorrelation of z is a ...

This paper presents the review of the Doubly fed Induction Generator (DFIG) based Wind Energy Conversion System (WECS). Basically the various challenges of the grid connected DFIG based wind turbine has been highlighted in this review. Nonlinear model of wind turbine with DFIG configuration are explained and a 1.2 MW, 50 Hz, 6 pole DFIG simulated using MATLAB/SIMULINK. Some important control is...

We survey some randomized search methods for global optimization that are based on sampling from an underlying probability distribution “model” on the solution space. In this approach, the probability model is updated iteratively after evaluating the performance of the samples at each iteration. Such model-based methods include estimation of distribution algorithms (EDAs), the cross-entropy met...

BACKGROUND Mineralocorticoid receptor antagonists (MRAs) are the most underutilized pharmacotherapy for heart failure. Minimal data are available on the barriers to MRA adoption from the perspective of prescribing clinicians. METHODS AND RESULTS A mixed-methods study consisting of a survey (n=50), focus groups (n=39), interviews (n=6) with clinicians at a single US Department of Veterans Affa...

Marine permanent magnet synchronous propulsion motors have problems, such as low reliability and difficult maintenance in the traditional control. In this paper, a sensorless control system for motor (PMSM) based on parameter identification is proposed. According to mathematical model of two-phase rotating coordinate system, reference adaptation (MRAS) used estimate rotor speed position motor. ...
