Development of Nonlinear Filtering Algorithms of Digital Half-Tone Images

This chapter is devoted to solving the problem of algorithms and structures investigations for Radio Receiver Devices (RRD) with the aim of the nonlinear filtering of Digital Half-Tone Images (DHTI) representing the discrete-time and discrete-value random Markovian process with a number of states greater than two. At that, it is assumed that each value of the DHTI element is represented by the binary g-bit number, whose bits are transmitted via digital communication links in the presence of Additive White Gaussian Noise (AWGN). The authors present the qualitative analysis of the optimal DHTI filtering algorithm. The noise immunity of the optimal radio receiver device for the DHTI filtering with varying quantization and dimension levels is investigated

Mathematical Models of Video-Sequences of Digital Half-Tone Images

This chapter is devoted to Mathematical Models (MM) of Digital Half-Tone Images (DHTI) and their video-sequences presented as causal multi-dimensional Markov Processes (MP) on discrete meshes. The difficulties of MM development for DHTI video-sequences of Markov type are shown. These difficulties are related to the enormous volume of computational operations required for their realization. The method of MM-DHTI construction and their statistically correlated video-sequences on the basis of the causal multi-dimensional multi-value MM is described in detail. Realization of such operations is not computationally intensive; Markov models from the second to fourth order demonstrate this. The proposed method is especially effective when DHTI is represented by low-bit (4-8 bits) binary numbers

The choice of technology hip arthroplasty with the tribological characteristics of implants

Studied the friction pair kinematic assembly hip replacements and hip human rabbits model of osteoarthritis in the dry friction and biological environment. In an experimental model of osteoarthritis in laboratory animals is illustrated by the direct correlation adhesive properties on the stage and depth of the process. Found that the tribological pair have studied various behavior characteristics depending on the magnitude of the external load and the 'hardness' of the kinematic junction.Изучены пары трения кинематического узла эндопротезов тазобедренного сустава человека и тазобедренных суставов кроликов с моделью остеоартроза в условиях сухого трения и биологической среды. В экспериментальной модели остеоартроза на лабораторных животных иллюстрируется прямая корреляция адгезионных свойств от стадии и глубины процесса. Установлено, что изученные трибологические пары имели различные характеристики поведения в зависимости от величины внешней нагрузки и «твердости» самого кинематического узла
