Цель
Создание трехмерной математической модели коронарного кровотока по данным компьютерной томографической ангиографии (КТА) с последующим расчетом фракционного резерва кровотока (ФРККТА). Сопоставление расчетного ФРККТА с результатами инвазивных измерений.
Материалы и методы
В исследование включено 10 больных с «пограничными» (50-75%) стенозами по данным КТА, выполненной на 640-срезовом компьютерном томографе. На основании данных КТА были построены трехмерные математические модели коронарных ...

The problem of forecasting multidimensional time series and mining rules in them
has received much attention. The hypothesis that a rule may change in the course
of time is also quite common. This paper is focused on mining rules that change
slightly in the course of time. This means that a rule may be replaced only by a
similar ...

The article considers dynamic processes involving non-linear power-law behavior in such apparently diverse spheres, as demographic dynamics and dynamics of prices of highly liquid commodities such as oil and gold. All the respective variables exhibit features of explosive growth containing precursors indicating approaching phase transitions/catastrophes/crises. The *rst part of the article analyzes mathematical models of demographic ...

A hierarchical method of mathematical and computer modeling of interval-stochastic thermal processes in complex electronic systems for various purposes is developed. The developed concept of hierarchical structuring reflects both the constructive hierarchy of a complex electronic system and the hierarchy of mathematical models of heat exchange processes. Thermal processes that take into account various physical ...
