The present study describes the case of a 27-year-old, right-handed female with bilateral mesial temporal lobe epilepsy. Electroencephalogram (EEG) monitoring from implanted electrodes displayed two different and independent onsets on the two sides of the mesial temporal structures, which specifically included clinical generalized tonic clonic seizure (GTCS) discharges originating from the left...

The apodization function has a significant impact on the state of art group delay, dispersion compensation, and acceptable decrease in side lobes spectrum Fiber Bragg Grating (FBG) reflection. Accordingly, grating length would be considered backbone parameter order to achieve distinguishable performance. Here, utilization influence presence FBG is compensator. In addition, we have implemented t...

Ultrasound imaging is one of the important noninvasive technique that using in medical diagnosis. Unfortunately the far field beam pattern in ultrasound is a sinc function which has a better main-lobe (the resolution of ultrasound imaging) and high side-lobe about 13dB down from the maximum on axis value (the contrast of ultrasound imaging).The result for that is one of a famous artifact in med...

This paper describes the synthesis of digitally excited pencil/flat top dual beams simultaneously in a linear antenna array constructed of isotropic elements. The objective is to generate a pencil/flat top beam pair using the excitations generated by the evolutionary algorithms. Both the beams share common variable discrete amplitude excitations and differ in variable discrete phase excitations...

We improve the timing attack on ECDSA in [1] by Brumley and Tuveri. We use the Gaussian heuristic to analyse the length of error vectors in the lattice Close Vector Problem in order to determine the problems which are theoretically solvable. Then we cost each solution using a strengthened lattice reduction algorithm and Schnorr-Euchner enumeration to determine which problems are practically sol...

In this paper we investigate comparative analysis of different antenna parameter (directivity, side lobe level and convergence time ) by using different type of optimizing technique such as Taguchi‟s, PSO, RCGA for synthesis of broad side and end fire linear antenna array in WI-MAX application. On ampere current is provided to each element and radiated power is decreases and radiation intensity...
