This paper analyzes the output feedback control of a class unknown nonlinear systems in presence measurement noise using multiple high-gain observers (MHGOs). It is well known that single (HGOs) are not able to provide satisfactory performance when system contaminated by noise, and turn, controllers, which utilize such estimations, perform poorly. To address this issue improve performance, bank...

We studied visual-vestibular interaction (VVI) in 9 normal human subjects using active and passive vertical head rotations. Gain and phase of the vertical vestibulo-ocular reflex (VOR) and visually enhanced vestibulo-ocular reflex (VVOR) were measured for single frequency sinusoidal motion, as well as for sinusoidal motion of continuously increasing frequency, over the range of 0.4 to 4.0 Hz. I...

Modern probe microphone systems offer a wide range of measurement options including a multiplicity of test signals. The signal of choice for any particular measurement is largely determined by the purpose in performing the measurement. For example, while a pure tone sweep would be fine for measuring a real-ear-to-coupler difference, the patient's own vocalizations would probably serve better fo...

this paper describes the design of a 2x2 micro strip patch antenna array in the frequency of 9.5ghz for radar applications, using substrate integrated waveguide, siw, for feeding network. the micro strip patches are aperture-coupled with the feeding network of siw. the feeding network consisting of a perpendicular coax-to-siw transition and two y-junction power dividers. the antenna is simulate...

One of the crucial tasks in quantum systems is to reduce effects decoherence due unavoidable interactions between a system and its environment. Many protection schemes have been proposed recently, among them weak measurement reversal (WMQMR), measurement-based feedback control (QFBC) feedforward (QFFC) are reviewed this paper. By considering measurement, aim find balance information gain distur...

This paper describes numerical analyses of the distancedependent gain variation that exists in gain measurements based on the Friis transmission formula for typical broadband antennas, including doubleridged guide horn and log-periodic dipole array antennas. The analyses are performed by simulating gain measurements using the method of moments with higher-order basis functions and the finite in...

Tailored gain semiconductor lasers capable of high-power operation with single-lobed, nearly diffraction limited beamwidths only a few degrees wide have been demonstrated in proton implanted chirped arrays and “halftone” broad area lasers. We analyze lasers with a linear gain gradient, and obtain analytic approximations for their unsaturated optical eigenmodes. Unlike a uniform array, the funda...

industrial organizations are complex systems` where the interactions among the various functions such as sales, distribution, manufacturing, materials, finance, human resources and maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. however, since most of these or-ganizations have a `functional structure`, each function or department works towards ...
