An efficient and reliable algorithm for selecting the optimal exposure in video cameras of technicalvision systems is proposed.
The algorithm is based on the Otsu binarization method. A theoretical justification of the convergence of the proposed algorithm
is given. At the end of the paper, we discuss software and hardware aspects of a real-world implementation of our algorithm,
which confirmed its efficiency and stability.

This paper presents an algorithm for segmentation of convex cells with partially undefined edges based on application of a
marker-controlled watershed transform to a combination of a source grayscale image and the result of a “geodesic distance”
morphological operation, applied to the result of binarization of a source image. The presented approach is used in computer
image processing systems for analysis of several industrial materials.
The text was submitted by the authors in English.

A thermodynamic analysis of an adsorption refrigerating plant with closed loops for a working substance and auxiliary liquid
heat carrier has been carried out in application to the adsorption pair “water-CaCl2 impregnated into the pores of a silica gel.” Using the obtained periodic solutions of the system of energy-balance equations
for the heat carrier and the sorbent layer, the most thermodynamically effective modes of operation of the refrigerating plant
have been determined as functions of governing parameters. The entropy production in various modules of the plant is calculated,
and the main sources of entropy generation are revealed. This made it possible to suggest an improved scheme of an adsorption
refrigerating cycle with regenerative heat exchangers connected at the inlet and outlet from the adsorbers. The possibility
of a considerable increase in the coefficient of thermodynamic efficiency in such a system has been justified.

An original method to estimate efficiency of the algorithms for opening and closing links in the wireless self-organizing networks (mesh networks) was proposed. It can be used to develop a mathematical model of the algorithm standardized in the mesh network specification IEEE 802.11s. The proposed method was shown to be sufficiently general and applicable to developing the models of other link management algorithms. 相似文献
