This paper is devoted to improving the search request processing productivity for planar discrete models used in engineering software. A data structure has been developed to accelerate the search for discretization elements based on a hierarchical triangular mesh.
Розглянуто основні підходи до описування та створення екоінформаційних систем на основі дискретних моделей та інформаційно-комп’ютерних технологій.
The paper describes the main approaches to the development of systems based on ekoinformation discrete models and computer technology.
Описано спосіб розрахунку теплофізичних характеристик композитних матеріалів зі складною внутрішньою структурою на основі дискретної моделі, що будується за методом теплоелектричних аналогій.
This paper consider the method of calculation the thermophysical characteristics of composite materials with complex internal structure based on the discrete model that is constructed by the method of thermal-electric analogies.
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
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.
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.
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.
