In this paper, we present a novel mathematical model for lossless video compression using Cartesian co-ordinate system. The model is based on our novel approach of explanation to the working principle of Median Edge Detector(MED). Median Edge Detector predicts value of the unknown pixel, xt, using previously encountered three pixel values . This is done using following prediction model.
This paper investigates the various effects that affect the ID-VDS characteristics in a strained-Si over SiGe NMOSFETs. The modeling is done keeping the BSIM4 parameters as the reference. The model thus developed showed precise agreement with the experimental data. It is observed that mobility in strained silicon increases and thereby enhancing current. Bandgap is affected to a lesser extent, but...
One of the main issues regarding a gaseous detector is the gas flow inside the detector itself. A bad gas flow can affect irreversibly the chamber performance. On the other hand optimizing gas circulation inside the detector could allow a safe and reliable operation even with less gas consumption while at the same time maintaining high performance. Simulations and comparison between several different...
Evaluating and possibly improving the fault tolerance and error detecting mechanisms is becoming a key issue when designing safety-critical electronic systems. The proposed approach is based on simulation-based fault injection and allows the analysis of the system behavior when faults occur. The paper describes how a microprocessor board employed in an automated light-metro control system has been...
The paper is devoted to problem of spline approximation. A new method of nodes location for curves and surfaces computer construction by means of B-splines and results of simulink-modeling is presented. The advantages of this paper is that we comprise the basic spline with classical polynomials both on accuracy, as well as degree of paralleling calculations are also shown.
A methodology to compute tunneling currents in a nanocrystal (NC) memory cell is presented to reveal the positive impact of using metal NCs as storage nodes. An analytical model for quantifying the NC effect on electrostatic potential has been used with a transmission line analogy-based quantum mechanical method to calculate the tunneling current. The model includes the effects of the electron wave...
