The temperature dependent magnetization of a two band model for diluted magnetic semiconductors as a function of magnetic coupling constant, hopping parameters and carrier densities is calculated by using the coherent potential approximation.  It is ... see more

We consider a model of III-V diluted magnetic semiconductors where both of the exchange interaction between carrier and impurity spins, and the direct exchange interaction between magnetic impurities are taken into account. The magnetization as a function... see more

The effect of the polarization orientation in the piezocomposites global characteristic has been studied and published. This work is inspired in this idea. In the present work, the effects of the magnetization orientation related to the effective properti... see more

Pure and metal doped hydroxyapatite samples nano-particles were prepared by the wet chemical method. Copper and cobalt is used in doping hydroxyapatite. Sample was prepared without change in the stoichiometric ratio of Ca/P and Ca+M/P inside the structure... see more

Background: Quantitative Magnetization Transfer Imaging (QMTI) is often used to quantify the myelin content in multiple sclerosis (MS) lesions and normal appearing brain tissues. Also, automated classifiers such as artificial neural networks (ANNs) can si... see more

The article was devoted to the study of an automated electric drive with a scalar closed-loop speed control system. Severe duty and operating modes of electric drive determine the actual service life. Wear of the induction motor, as a key link of the elec... see more

Utilization of biodiesel results in lower emissions of hydrocarbons, carbon mono oxide, and smoke. But with the use of biodiesel as fuel emission of Oxides of nitrogen increases along with this some performance parameters also deteriorated. In the present... see more

The sinusoidal magnetization of a sample material is difficult toachieve, since the magnetic hysteresis poses a strongnon-linearity. In order to find the proper input voltage, afeed-forward strategy with a hysteresis model identification andinversion is p... see more

Padang city has landfill located in Air Dingin Village Balai Gadang  Koto Tangah Subdistrict of Padang. This landfill has some leachates  that assumed there is seepage from leachate pond to the river and drain. The results observation present th... see more
