This paper introduces a new Windowed Green Function (WGF) method for the numerical integral-equation solution of problems of electromagnetic scattering by obstacles in presence of dielectric or conducting half-planes. The WGF method, which is based on use of smooth windowing functions and integral kernels that can be expressed directly in terms of the free-space Green function, does not require...

Cognitivism has dominated mainstream psychology for decades, but lately its position has been weakened. It has been criticized not only by behavior analysts but also by social and evolutionary psychologists, neuroscientists, and authors who are or used to be cognitivists themselves. At the same time, psychologists and neuroscientists in several fields are now rediscovering the necessity of unde...

The challenges with respect to mining frequent items over data streaming engaging variable window size and low memory space are addressed in this research paper. To check the varying point of context change in streaming transaction we have developed a window structure which will be in two levels and supports in fixing the window size instantly and controls the heterogeneities and assures homoge...

The fast Fourier transform (FFT), which is employed by all commercially available ultrasonic systems, provides a time-frequency representation of Doppler ultrasonic signals obtained from blood flow. The FFT assumes that the signal is stationary within the analysis window. However, the presence of short duration embolic signals invalidates this assumption. For optimal detection of embolic signal...

Complexity analysis in heterogeneous system is one of the more complicated topics in the subject mathematics for computing. It involves an unusual concept and some tricky algebra. This paper shows how various algorithms take part in heterogeneous system and how they affect the overall system complexity? All analysis and methods are situation specific. Here we show a comparative study of various...

The inner layer of the round window membrane is composed of mesothelial cells and this mesothelial cell layer extends to the scala tympani. This study describes the histopathologic findings of temporal bone analysis from a patient with bilateral perilymphatic fistula of the round window membrane. The left ear showed proliferation of mesothelial cells in the scala tympani of the basal turn adjoi...

seismic attributes are very useful in seismic data interpretation. one of these attributes is the coherency attribute. seismic coherency is a complex trace and a geometrical attribute that is applied to a 3d cube of seismic data. it is a measure of lateral changes in acoustic impedance caused by the variation in structure, stratigraphy, lithology, porosity, and the presence of hydrocarbons. whe...

Introduction: In radionuclide imaging, object scatter is one of the major factors leading to image quality degradation. Therefore, the correction of scattered photons might have a great impact on improving the image quality. Regarding this, the present study aimed to determine the main and sub-energy windows for triple energy window (TEW) scatter correction method usin...

We numerically investigate the ability of ambient noise surface wave interferometry to invert for anelastic attenuation. Shorter correlation time windows leads to higher signal-to-noise ratio of empirical Green’s functions (EGF’s). We show, however, that it is necessary to correct for the window length and that this is especially important if short time windows are employed. Furthermore, we sho...

The optimal window, the time limited sequence whose energy is most concentrated in a nite frequency interval is related to a particular discrete prolate spheroidal sequence. The optimal window is actually a family of windows with many degrees of freedom. The Kaiser window is an approximation to this optimal window. Kaiser used this approximation because the standard method employed to compute t...
