This paper deals with the modeling of DC-DC boost chopping circuit in a huge-power chopping cascade speed regulation system while the motor power level is over 1 megawatt. The model involves the Insulated Gate Bipolar Translator(IGBT) & Free-Wheel Diode(FWD) based on a state-space averaging method. It solves the problems of the designing of a control system in the chopping cascade speed regulat...

A Rasch-type loneliness scale was administered in two separate studies. The fwd involved a sample of 708 unemployed, occupationally disabled and employed men and women. The second involved a sample of 412 married, unmarried, divorced and widowed women and men. The efects of being with or without a partner, the respondents' evaluation of the supportive function of the partner, and different type...

Although membrane addition is crucial for cytokinesis in many animal cell types, the specific mechanisms supporting cleavage furrow ingression are not yet understood. Mutations in the gene brunelleschi (bru), which encodes the Drosophila ortholog of the yeast Trs120p subunit of TRAPPII, cause failure of furrow ingression in male meiotic cells. In non-dividing cells, Brunelleschi protein fused t...

A falling weight deflectometer (FWD) is commonly utilized to make structural evaluation of pavement systems, which applies impulsive force at a surface of pavement and measure surface deflections. Static back-calculation employs only peak force and peak deflections, while dynamic back calculation uses time histories of both. Since dynamic analysis of elastic multi-layered systems required in it...

<p style='text-indent:20px;'>The evaluation of asphalt pavement structures has been a critical challenge in the field due to practical limitations methodology. In this paper, we propose data-driven framework evaluate structural performance nineteen widely used Research Institute Highway Ministry Transport track (RIOHTrack). Specifically, utilize unsupervised machine learning method deline...

Currently, the network traffic classification has two important problems, which are low accuracy and high computation complexity. In order to solve these problems, a novel network traffic classification method using support vector machine with feature weighted-degree (FWD-SVM) is proposed in this study. Our method can efficiently reduce the influence on the sample distribution, relative propert...

This contribution presents the results of comparison of Dutch texts written by bilinguals I) (speaking French and Dutch), with Dutch texts regarded as STANDARD WRITTEN DUTCH. The attention was focussed on French loan-words appearing in both types of texts and the differences in their use. Certain generalizations as to the mechanisms of interference are suggested. The materials used for the pres...

On the example of the road pavement of a semi-rigid structure, this paper presents the concept of the parameters estimation of the experimental section tested after 30 years of use. In the context of the lack of technical history data of the analyzed road section, the resultant (conventional multilayer system, which is pavement and its subgrade) stiffness was analyzed in relation to the moment ...
