the vast use of linear prediction coefficients (lpc) in speech processing systems has intensified the importance of their accurate computation. this paper is concerned with computing lpc coefficients using evolutionary algorithms: genetic algorithm (ga), particle swarm optimization (pso), dif-ferential evolution (de) and particle swarm optimization with differentially perturbed velocity (pso-dv...

The vast use of Linear Prediction Coefficients (LPC) in speech processing systems has intensified the importance of their accurate computation. This paper is concerned with computing LPC coefficients using evolutionary algorithms: Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Dif-ferential Evolution (DE) and Particle Swarm Optimization with Differentially perturbed Velocity (PSO-DV...

In the smart campus, sensors are basic units in whole Internet of Things structure, which play role collecting information and transmitting it. How to transmits more at a certain power level has attracted attention many researchers. this paper, DV-Hop algorithm is optimized by combining simulated annealing-interference particle swarm optimization improve node localization wireless sensor networ...

background: primary health care physicians (phcps) are the first in the clinic to detect and help victims of intimate partner violence (ipv). therefore, their attitude and practice toward domestic violence (dv) are important to manage this problem. the aim of current study was to compare the behavior and attitude of phcps about dv versus other health risk factors in tehran, iran.   methods : a ...

  Background: Primary health care physicians (PHCPs) are the first in the clinic to detect and help victims of intimate partner violence (IPV). Therefore, their attitude and practice toward domestic violence (DV) are important to manage this problem. The aim of current study was to compare the behavior and attitude of PHCPs about DV versus other health risk factors in Tehran, Iran.   Methods : ...

Distant luminous quasars provide important information on the growth of the first supermassive black holes, their host galaxies and the epoch of reionization. The identification of quasars is usually performed through detection of their Lyman-α line redshifted to 0.9 microns at z > 6.5. Here, we report the discovery of a very Lyman-α luminous quasar, PSO J006.1240 + 39.2219 at redshift z = 6.61...

Data Virtualization (DV) has become an important method to store and handle data cost-efficiently. However, it is unclear what kind of data and when data should be virtualized or not. We applied a design science approach in the first stage to get a state of the art of DV regarding data integration and to present a concept matrix. We extend the knowledge base with a systematic literature review ...

Two efficient and practical methods of synthesis of the C-10 substituent of DV-7751 (1), a novel quinolone carboxylic acid, were established. The first method utilizes an optical resolution of racemic 8-amino-6-benzyl-6-azaspiro[3.4]octane (13), while the second employs an enantioselective microbial reduction of 6-benzyl-5,8-dioxo-6-azaspiro[3.4]octane (8b). The enantiomeric excess of (S)-8-ami...
