The paper provides a brief critical review of the original mathematical models carbohydrate exchange regulation system from historically first works to its most advanced model. Their significant deficiencies were mentioned. To eliminate them, it was carring out construction minimal, but universal, structural and functional model this physiological system, for program-model extraction diagnostic information glycemic data glucose tolerance tests. presents itself differential equation order...

Due to the fact that blood in human body plays a crucial role for flow of vital metabolic processes -the study red cells is great scientific and medical interest. This due erythrocyte morphology has changes not only hematological diseases, but also reflects state organism as whole. The paper proposed technical solution uses method holographic interferometry obtain three-dimensional image erythrocytes. suggests optimization formation reference object beam rays device, which significantly...

Abstract This paper presents a novel converter which can reduce the harmonics like conventional multipulse converters with input three phase transformer. To total harmonic distortion of current and improve weight size converters, it is suggested to use multi-pulse rectifiers an electronic shift. The basic module 6-pulse rectifier on fully controlled switches reverse blocking ability. Switching frequency either coincides or twice power frequency. proposed solutions allow refusing from...

In the issue of improving quality telemedicine visual diagnostics, current task is to increase reliability differential diagnostics and assess severity disease. This primarily due widespread introduction virtual methods according criteria evidence-based medicine. An important task, in this case, choice informative parameters control, as well by which discriminant capabilities will be compared. The authors have carried out research into possibility using an integrated approach studying...

An algorithmic block of biotechnical system the quantitative diagnostics glucose malabsorption on base conversion oral to lerance test glycemic data into necessary diagnostical parameters by use original mathematical model carbohydrate metabolism regulation was elaborated. A new diagnostic parameter, characterising a degree absorption in intestine, suggested as well criteria it. Diagnostics parameter compared with means "sugar loads" and "glucose intensity" methods.

An active filter control strategy that uses pqr instantaneous power concept has been proposed to compensate for the harmonic distortion, line neutral current and reactive in three-phase four-wire systems. The effectiveness of was proved simulations using Matlab/Simulink model power-supply system with an where pollution, imbalance caused by a highly distorting load have drastically reduced.

The article gives a brief overview of the state solution an important scientific and applied problem mathematical modeling physiological system carbohydrate exchange regulation. It shows that for half century all previous attempts to solve it have been physiologically inadequate. demonstrates model has proposed little more than twenty years ago is yet known community, which most minimal regulation in form homeostatic self-regulation glycemic level single variable at periphery. This...

At present, 12-pulse rectifiers with electronic phase shift are known. Unlike classic rectifiers, they do not use phase-shifting transformers and have a unit power factor. Increasing of the rectifier's pulse makes it possible to improve harmonic composition input current. This article is devoted study operation an 18-pulse rectifier shift. The principle leads different levels constant voltage at output rectifiers. introduction pulse-width modulation contributes equalizing voltages 6-pulse...
