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...

due to the fact that the error surface of adaptive infinite impulse response (iir) systems is generally nonlinear and multimodal, the conventional derivative based techniques fail when used in adaptive identification of such systems. in this case, global optimization techniques are required in order to avoid the local minima. harmony search (hs), a musical inspired metaheuristic, is a recently ...

the main objective of this study is the modelling and optimization of an industrial hydrocracker unit (hu) by means of adaptive neuro fuzzy inference system (anfis) model. in this case, some data were collected from an industrial hydrocracker plant. inputs of an anfis include flow rate of fresh feed and recycle hydrogen, temperature of reactors, mole percentage of h2 and h2s, feed flow rate and...

For speed sensorless induction motors under field-oriented control (FOC), where the motor speed and angle are not measured, the speed control tracking bandwidth is mainly limited by the convergence rate of the state estimator. Prevailing speed-sensorless induction motors suffer significant performance degradation from removing the encoder, which limits their applications to fields requiring low...

We present observations of 86 meteor radio afterglows (MRAs) using the new broadband imager at Long Wavelength Array Sevilleta (LWA-SV) station. The MRAs were detected all-sky images with a bandwidth up to 20 MHz. fit spectra both power law and log-normal function. When law, varied from flat steep derived spectral index distribution peaked -1.73. function, exhibits turnovers frequencies between...

RESUMO O organismo materno sofre alterações fisiológicas e biomecânicas durante a gestação, dentre elas o afastamento dos músculos retos do abdome (MRAs). Os objetivos deste estudo transversal foram: comparar distância entre os MRAs primíparas treinadas sedentárias que realizaram parto vaginal cesárea; correlacionar com variáveis materno-infantis; essas sem diástase MRAs. Foram avaliadas 56 mul...

A growth in cultural ideologies concerned with men and masculinities in contemporary American society has recently emerged. Men’s rights activist (MRA) groups embody a movement emphasizing the crisis of masculinity. Despite men’s privileged societal status, MRAs seek to establish resources for men to utilize in elevating their perceived subordinated position in society in relation to women and ...
