discrete model


This work is devoted to improving the processing speed of search requests to planar discrete models used in engineering software. A data structure has been developed to speed up the search for discretization elements based on a hierarchical triangulation grid.

Modeling and mathematical analysis of drug addiction with the study of the effect of psychological and biological treatment

In this article, we propose a discrete mathematical model which describes the propagation of the drug phenomenon in a human population.  The population is unscrewed in five compartments: "$S$" People likely to become drug addicts, "$M$" Moderate drug addicts, "$H$" Heavy drug addicts, "$T$" People receiving drug addiction treatment, "$R$" The recovered people who have completely abstained from drug addiction.  Our goal is to find a better strategy to reduce the number of heavy addicts and to maximize the number of people receiving full treatment.  The tools of optimal c

Finding effective thermal characteristics of composite materials based on the analysis of thermal conductivities

This paper presents a method and algorithm for finding effective thermal characteristics of composite materials, with complex internal structure by the method of thermal-electrical analogies based on the discrete model that built for the task of analysis of the temperature field by finite element method.

Функційні можливості системи розпізнавання та ідентифікації користувачів комп’ютера на основі дискретних моделей

In the article the description the system of computer users recognition is offered by means discrete model, that relations the sentinel delays at entered information from a keyboard in the to discrete moment of time. It allowed to increase efficiency of recognition almost in 1,5 time and automates procedure of authentication of users. The main directions of development and application of the systems of recognition and identification created on the basis of discrete models are marked.

Аналіз методів та підходів до побудови систем розпізнаваннята ідентифікації користувачів комп’ютера на основі інформаційних моделей

In this paper we present the comparative methods and algorithms analysis of computer users recognition systems construction with the help of informative keyboard handwriting models. Such analysis allows defining features of each considered approach its advantages and disadvantages as well as the directions of the expedient use.
