Resistance spot welding with its characteristic “dirty electrical load” is adistinctive engineering problem. The wide range of industrial applications has made the subject an exciting research domain. Owing to in term it tence a operation, random overlapping pulses, sensitivity voltage variation and application-specific quality control requirements, distribution system for loads need be tied st...

Separating technique for singing voice from music accompaniment is very useful in original sound type Karaoke instrument. We propose a real-time system to separate singing voice from music accompaniment for stereo recordings. Proposed algorithm consists of two stages. The first stage is a spectral change detector. The last stage is a selective vocal separation in frequency bins. Our system cons...

spatial planning system of a country is the array of its planning systems. getting familiar with spatial planning system of different countries and their experiences could help for comparison and accommodation so that making decision and defining appropriate planning system could be done. this article has studied the spatial planning system of portugal and since there are different factors affe...

This article describes the development of DSP as the core of the face recognition system, on the basis of understanding the background, significance and current research situation at home and abroad of face recognition issue, having a in-depth study to face detection, Image preprocessing, feature extraction face facial structure, facial expression feature extraction, classification and other is...

Independently, programmable truncated multipliers also achieve power benefits at the expense of degradation of the output signal-to-noise ratio Fault tolerant techniques can extend the power savings achieved by dynamic voltage scaling by trading accuracy and/or timing performance against power. Such energy improvements have a strong dependent on the delay distribution of the circuit and the sta...

this paper presents an application of benders decomposition to deal with the complexities in the simultaneous generation expansion planning (gep) and transmission expansion planning (tep). unlike the power system operation fields of study, the power system planning methods are not expected to be fast. however, it is always preferable to speed up computations to provide more analysis options for...

The harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. This paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. The objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...

One of the most important obstacles in the deployment of the clean technologies such as photovoltaic modules in the distribution system is their indefinite future in the coming years after the installation due to their intermittent nature in power generation because of the dependency to solar radiance profile. The authors in this study aim to analyze the economic, technical and environmental ef...
