It is well known that ocean waves are an important component of upper ocean dynamics. The synthetic aperture radar (SAR) has been widely used to measure ocean surface wave spectra from space since the Seasat satellite was launched in 1978. Many papers have been published dealing with the imaging mechanism and retrieval methodology. Schuler and Lee proposed a method to improve the measurement of...

conclusions this study highlights the close link between the role of the phrenic nerve and pulmonary function, such that the use of this nerve as a transfer donor leads to spirometric impairments. results all patients regained biceps power to m3 strength or above. none of our patients experienced pulmonary problems or respiratory complaints, but a significant reduction of spirometric parameters...

In this article, a special type of orthogonalization is obtained to construct a multiple input transfer function model. By using this technique, construction of a transfer function model is divided to sequential construction of transfer function models with less input time series. Furthermore, based on real and simulated time series we provide an instruction to adequately perform the stages of ...

Abstract The investigation of thermal modulation on double-diffusive stationary convection in the presence an applied magnetic field and internal heating is carried out. A weakly nonlinear stability analysis has been performed using finite-amplitude Ginzburg-Landau model. This finite amplitude obtained at third order system. study considers three different forms temperature modulations. OPM-out...

Radial frequency (RF) patterns, which are sinusoidal modulations of a radius in polar coordinates, are commonly used to study shape perception. Previous studies have argued that the detection of RF patterns is either achieved globally by a specialized global shape mechanism, or locally using as cue the maximum tangent orientation difference between the RF pattern and the circle. Here we challen...

We used diffraction modulation transfer functions and model eyes to predict the effect of defocus on the contrast sensitivity function (CSF) and compared these predictions with previously published experimental data. Using the principle that optically induced changes in the modulation transfer function should be paralleled by identical changes in the CSF, we used the modulation transfer functio...

PURPOSE To assess the crystalline lens opacity level by measuring ocular light scattering with a double-pass system. DESIGN Prospective, single-center, cross-sectional study. METHODS Two hundred fifty-three eyes of 135 patients referred for cataract evaluation were enrolled. Patients with corneal or retinal anomalies potentially impairing ocular transparency were excluded. Lens opacificatio...

Main task of power semiconductor converter is transfer of electrical energy from its input to the output and to the load. This energy flow is provided by control of the switching process of one or more semiconductor devices. Based on converter application it is necessary to choose correct control algorithm for selected switching frequency of converter. Algorithm itself has to be utilized with s...

This article focuses on the in-phase/quadrature (I/Q) imbalance problem in quadrature ΣΔ modulators (QΣΔM). In the literature, such quadrature modulators have been seen as a promising possibility for software defined radio (SDR) receivers, but matching the quadrature circuits is an inevitable problem for this kind of systems. In this article, an analytic closed-form model will be derived for a ...
