H-bridge inverter is a common topology used for single-phase applications. Due to its limited voltage gain, two-stage power conversion with front-end dc-dc converter usually adopted accommodate the low dc source voltage. Recently, single-stage boost inverters are gaining significant interest due their higher efficiency and compactness. This paper presents family of continuous current. By incorp...
Kebutuhan terhadap sistem antrian pada saat ini menjadi hal yang dinilai penting. Studi literatur telah dilakukan menunjukkan bahwa dikembangkan bersifat spesifik untuk satu proses atau instansi tertentu saja. Oleh karena itu, tujuan dari penelitian adalah merancang dan mengembangkan dapat digunakan oleh siapapun dengan struktur single-channel single-phase. Metodologi menggunakan design science...
In this paper, we compare logistic regression and 2 other classification methods in predicting hypertension given the genotype information. We use logistic regression analysis in the first step to detect significant single-nucleotide polymorphisms (SNPs). In the second step, we use the significant SNPs with logistic regression, support vector machines (SVMs), and a newly developed permanental c...
a method based on electrical capacitance tomography (ect) and an improved least squares support vector machine (ls-svm) is proposed for void fraction measurement of oil-gas two-phase flow. in the modeling stage, to solve the two problems in ls-svm, pruning skills are employed to make ls-svm sparse and robust; then the real-coded genetic algorithm is introduced to solve the difficult problem of ...
In this paper, the phase properties of waves reflected from one-dimensional double-periodic quasi-crystals consisting of single-negative materials are investigated using transfer matrix method. It is observed that, by increasing the double-periodic generation number, a large omnidirectional band gap is created in the single-nagative frequency range. We limit our studies to the frequency range o...
This paper presents a new single to three phase converter using rotating magnetic field transformer. Conventional transformers have been used in many converters aiming at supplementary improvements and they usually have no critical effect on the conversion technique. In this paper, the conversion technique is based on a special rotating magnetic field transformer in which there are two windings...
superparamagnetic single phase zinc ferrite nanoparticles have been prepared by coprecipitation method at 20 °c without any subsequent calcination. the composition, crystallite size, microstructure and magnetic properties of the prepared nanoparticles were investigated using x-ray diffraction (xrd), field emission scanning electron microscope (fesem), transmission electron microscope (tem), fou...
