Fast and Accurate Simulation

Yehea I. Ismail Department of Electrical and Computer Engineering Northwestern University Evanston, IL. 60208 Abstract A method is introduced to evaluate time domain signals witbin RLC trees with arbitrary accuracy in response to any input signal. This method depends on finding a low frequency reduced order transfer function by direct truncation of the exact transfer function at Merent nodes of...

A Fast and Accurate Expansion-Iterative Method for Solving Second Kind Volterra Integral Equations

This article proposes a fast and accurate expansion-iterative method for solving second kind linear Volterra integral equations. The method is based on a special representation of vector forms of triangular functions (TFs) and their operational matrix of integration. By using this approach, solving the integral equation reduces to solve a recurrence relation. The approximate solution of integra...

Fast and accurate phase unwrapping

More and more speech technology and signal processing applications make use of the phase information. A proper estimation and representation of the phase goes inextricably along with a correct phase unwrapping, which refers to the problem of finding the instance of the phase function chosen to ensure continuity. This paper proposes a new technique of phase unwrapping which is based on two mathe...

Accurate and Fast Iris Segmentation

A novel iris segmentation approach for noisy iris is proposed in this paper. The proposed approach comprises of specular reflection removal, pupil localization, iris localization and eyelid localization. Reflection map computation is devised to get the reflection ROI of eye image using adaptive threshold technique. Bilinear interpolation is used to fill these reflection points in the eye image....
