In this work, we consider output-feedback distributed model predictive control (DMPC) based on state estimation with bounded process disturbances and output measurement noise. Specifically, a scheme observer-enhanced moving horizon (DMHE) is considered for purposes. The DMHE ensures that the estimates of system reach small neighborhood actual values quickly then maintain within neighborhood. Th...

pulse-width modulated (pwm) adjustable frequency drives (afds) are extensively used in industries for control of induction motors. it has led to significant advantages in terms of the performance, size, and efficiency but the output voltage waveform no longer remains sinusoidal. hence, overshoots, high rate of rise, harmonics and transients are observed in the voltage wave. they increase voltag...

the codling moth, cydia pomonella, is the most important pest insect in apple orchards. efficacy of a native strain of the egg parasitoid wasp, trichogramma embryophagum, was statistically compared with chemical control and check treatments in an apple orchard. the best times for releasing the parasitoid wasps were determined by using a forecasting model based on estimation of growing degree ho...

Population-Based Incremental Learning (PBIL) is an abstraction of a genetic algorithm , which solves optimization problems by explicitly constructing a probabilistic model of the promising regions of the search space. At each iteration the model is used to generate a population of candidate solutions and is itself modiied in response to these solutions. Through the extension of PBIL to Real-val...

The purpose of this study is to identify the effect of Ordinary Kriging (OK) and Inverse Distance Weighted (IDW) estimation methods for the delineation of mineralized zones based on subsurface data using concentration–volume (C–V) multifractal modeling in the Dardevey iron ore deposit, NE Iran. Variograms and anisotropic ellipsoid were generated for the Fe distribution by the above estimation m...

Terahertz (THz) band is expected to be one of the key enabling technologies sixth generation (6G) wireless networks because its abundant available bandwidth and very narrow beamwidth. Due high frequency operations, electrically small array apertures are employed, signal wavefront becomes spherical in near-field. Therefore, near-field model should considered for channel acquisition THz systems. ...

parameter estimation of the nonlinear muskingum model is a highly nonlinear optimization problem. although various techniques have been applied to optimize the coefficients of the nonlinear muskingum flood routing models, but an efficient method for this purpose in the calibration process is still lacking. the accuracy of artificial bee colony (abc) algorithm is investigated in this paper to op...
