A model and simulation software for faults detection, analysis and prediction in multi-layered and single layered printed circuit boards is presented. Fault detection is an intricate process; an engineer must apply wits to search for ways of rectifying and preventing the faults inherent in any electronic device. By application of several electronic paradigms on raw data from test equipments, th...

This paper presents an improved electronic circuit for testing photovoltaic (PV) modules or strings by tracing their I-V and P-V characteristics. It consists of an electronic fast varying load based on a power MOSFET controlled by means of an innovative sweeping gate-source voltage in order to improve the tracing of the I-V characteristics on an oscilloscope. In order to prevent damage of data ...

In recent years, automated human tracking over camera networks is getting essential for video surveillance. The tasks of tracking human over camera networks are not only inherently challenging due to changing human appearance, but also have enormous potentials for a wide range of practical applications, ranging from security surveillance to retail and health care. This review paper surveys the ...

The continuous scaling for fabrication technologies of electronic circuits demands the design of new and improved simulation techniques for integrated circuits. Therefore, this work shows a new double bounded polynomial homotopy based on a polynomial formulation with four solution lines separated by a fixed distance. The new homotopy scheme presents a bounding between the two internal solution ...

Trade-off is one of the main design parameters in the field of electronic circuit design. Whereas smaller electronics devices which use less hardware due to techniques like hardware multiplexing or due to smaller devices created due to techniques developed by nanotechnology and MEMS, are more appealing, a trade-off between area, power and speed is inevitable. This paper analyses the trade-off i...

Evolvable hardware (EHW) has attracted increasing attention since the early 1990’s with the advent of easily reconfigurable hardware, such as field programmable gate arrays (FPGA’s). It promises to provide an entirely new approach to complex electronic circuit design and new adaptive hardware. EHW has been demonstrated to be able to perform a wide range of tasks from pattern recognition to adap...

Given a graph G = (V, E), we want to find the vertex sets of the components of an unknown subgraph F = (V,E) of G, such that E ⊆ E. We learn about F by sending an oracle a query set S ⊆ V , and the oracle tells us the vertices connected to S in F . The objective is to use the minimum number of queries to partition the vertex set V into components of F . In electronic circuit design, the problem...

Chua’s circuit is a simple electronic circuit exhibiting a wide variety of bifurcation and chaotic phenomena. Because of its universality and simplicity, Chua’s circuit has captured much interest among researchers in science and engineering. The circuit equations are described by the following set of differential equations: C1 dVC1 dt = 1 R (VC2 − VC1) − F (VC1) , C2 dVC2 dt = 1 R (VC1 − VC2) +...

We demonstrate experimentally the regime of ghost stochastic resonance in the response of a Monostable Schmit Trigger electronic circuit driven by noise and signals with N frequency components: kf0 +∆f, (k+1)f0 +∆f, . . . , k+nf0 +∆f where k is an integer greater than one. It is verified that stochastic resonance occurs at the frequency fr = f0 + (∆f/(k+ (N − 1)/2)), as predicted in the theory....
