This paper presents a genetic algorithm for the restrictive channel routing problem. The major difference of the algorithm from already known genetic algorithms for this problem consists of the use of information about horizontal and vertical constraints in chromosome encoding that allow prevention of “illegal” solutions. This representation leads to lower complexity, because solution repairing...

This paper introduces a depth-computation architecture designed for, but not limited to, a single-chip current mode analog VLSI (aVLSI) implementation of stereo vision. The architecture implements a modified version of the block matching algorithm; pixel blocks are averaged (summed) vertically before comparison along the horizontal axis. This both reduces the effects of noise and provides an or...

In this paper we present a generic, uniformly randomized scalar multiplication algorithm based on covering systems of congruences, with built-in protections against various side-channel attacks. It has been tailored to resist a recent class of attacks called horizontal attacks. These very powerful attacks exploit some unsuspected weaknesses hidden in most, if not all, highly regular and constan...

We use Interferometric Synthetic Aperture Radar (InSAR) data to derive continuous maps for three orthogonal components of the co-seismic surface displacement field due to the 1999 Mw7.1 Hector Mine earthquake in southern California. Vertical and horizontal displacements are both predominantly antisymmetric with respect to the fault plane, consistent with predictions of linear elastic models of ...

Although the Turing-machine model of computation is widely used in computer science it is fundamentally inadequate as a foundation for the theory of modern scientific computation. The real-number model is described as an alternative. Physicists often choose continuous mathematical models for problems ranging from the dynamical systems of classical physics to the operator equations and path inte...

The purpose of this study is to explore how well dissonance fits as an alternative for a harmonic-related perceptual feature that is easily rated by human listeners. Dissonance is a well-known concept, often described as a sensation of roughness, tension and unpleasantness. For example, dissonant intervals comprised of complex tones have partials that don’t align and therefore give rise to beat...

abstract : horizontal root fractures in permanent teeth are uncommon injuries among dental traumas. the principle of treating horizontal root fractures of permanent teeth is repositioning and fixation of fractured segment. diagnosis of tooth fractures based on radiographic findings and the fracture healing process are affected by factors before and after injury. the present case reports the tre...

A motion adaptive de-interlacing algorithm and its hardware architecture are presented in this paper. It consists of the directional interpolation ELA with median processing, and 4-field horizontal motion detection. The edges can be sharper while the ELA with median processing is adopted. Enhanced ELA with median processing can prevent the happening of the bursting pixels. Proposed 4-field hori...
