    Mathematical Model of the Production Processes, Taking into Account Their Specific Features
  • Abstract
    • Statement of the problem. Stationary Queuing systems are standard mathematical model to describe many engineering, biological and other systems. However, in areas such as automation process control, management of environmental monitoring, planning combat actions, real systems are characterized by running in unsteady mode. The parameters of the real systems depend on the States of the system. Non-stationary queueing systems as mathematical models of these real systems are more than adequate. These queueing systems are formalized on the basis of systems of differential equations. The purpose of the work. We have developed and investigated a mathematical model of the production process on the basis of non-stationary queueing systems. Production processes are considered In work with consequent time and cellular spatial structure typical of small serial type production.

    Search Algorithms for Constrained Pseudo-Boolean Optimization
  • Abstract
    • Problem statement. The issue is the problem of optimizing real functions of binary variables that is the so-called pseudo-Boolean optimization problem. In many practical problems, possible combinations of variables are restricted by constraints that narrow the set of admissible values of the control variables. At the same time these constraints (and an objective function) often have structural properties, inclusion of which in the optimization process can improve the efficiency of solving such problems. Furthermore, in many real problems of optimization a part of functions (criteria and constraints) or all functions are defined algorithmically, which makes it impossible to apply the standard algorithms and requires the development of search optimization procedures. Purpose. To justify, construct and research methods for constrained pseudo-Boolean optimization problems with algorithmically given functions. Methods. Research of properties of the space of Boolean variables and detection of patterns for behavior of pseudo-Boolean functions in the space of Boolean variables. Development of exact regular algorithms that implement properties of specific classes of problems. In the development of regular algorithms, the classes of unimodal, monotone and structurally monotone pseudo-Boolean functions are considered. For large-scale problems research of algorithms based on a random search method that search among the boundary points of the feasible set. Results. The new exact algorithms with analytical estimates of complexity for solving the constrained pseudo-Boolean optimization problems. These algorithms realize information complexity of the problem classes. As well the new approximate algorithms are constructed for constrained optimization of monotone pseudo-Boolean functions with a large number of variables. Practical relevance. The developed algorithms are useful for solving all practical problems which are reduced to optimization problems of pseudo-Boolean functions. So, the problem of optimizing the capacity utilization of foundry is solved. The developed algorithms are used for finding logical patterns (used for building classifiers) in data that is the constraint pseudo-Boolean optimization problem of large dimension.

    Sharpening of Video Frames for Improvement of Feature Points Detection
  • Abstract
    • Some visual tracking tasks are unable to operate stable for video with blurred frames because feature points detection is degraded on blur images. In the paper we concentrate on blurriness due to refocusing of camera optical system of mobile devices. Our aim is evaluation of influence of blur and sharpening on Harris corner and FAST keypoints detectors. We propose a quality criterion in order to be able to make numerical assessment of the influence. For enhancement of blurred frames we investigate two sharpening filters: local tone mapping decreases of edge transition slope length, unsharp mask via bilateral filter increases local contrast along edges. On data from KITTI Vision Benchmark Suite as well as video captured by smartphone we demonstrate that sharpening improves feature points detection for both Harris corner and FAST methods. A positive impact for FAST is significant, it may improve robustness of various computer vision systems.

The VIPs feature in that it ensures the preservation of the range of the recognition and targeting at the fall of the temperature contrast of the object with the background not less than 10 times compared with a normalized value. System clock and all-weather operation created with the application of CCL on the basis of specific examples, including a universal sighting complexes, combined infra-red illuminators-target designators, laser rangefinders and lidars. Practical value: the results can be used to create instruments for observation, aiming, driving patrol vehicles, aiming and targeting, accurate measurement of range and speed weatherproof and persistent action in the interest of the security services and police, as well as all weather systems atmospheric laser communication. The use of CCL in the inspection system based on the use of T-rays will work in the range of to 300 microns and to create a portable and mobile equipment. The use of CCL in atmospheric laser communication systems to ensure all-weather capability. The prospects for further development of the results – application in devices more powerful CCL with power exceeding 100 watts in CW and in pulsed mode at room temperature, do high efficiency. CCL when working in continuous mode above 30%, the creation of CCL for short-wave spectral region from 2 to 4 μm, a gap of 20 to 70 μm in the working range of wavelengths CCL, increase the power of terahertz radiation CCL and do their work in thermoelectric cooling. Conclusions: the new generation of devices for security systems and communications allows you to eliminate the known disadvantage of the NT – the sharp decline in their range at low temperature of the object contrasts with the background. For measurements of distance, speed and the atmospheric connection is to provide year-round and all-weather performance.

  • Abstract
    • Relevance. The existing approaches to the calculation, analysis, synthesis and optimization of systems in conditions of uncertainty. The studying of uncertain systems is formulated in the form of tasks of calculation, analysis and synthesis of various nondeterministic functions with parameters that serve as the respective characteristics of these systems. These problems are much more difficult their deterministic counterparts which should be solved in the study of systems with deterministic (exactly known) parameters. Complication is due to the fact that the algebra of undetermined numbers more complicated than algebra of deterministic numbers. The purpose. This article is formulated and described in detail the problem of calculating and analyzing the behavior of a particular function which is not fully given (only up to a range of values). Method. To solve this problem there is provided a method of determination, which reduces the problem to the two same – for the upper and lower boundary functions of the original incompletely defined function. In this method we use the apparatus of interval mathematics and interval-differential calculus. We distinguish different types of possible behavior of interval functions (consistency, increase, decrease, expansion, restriction) and various types of extreme points of functions (on a sample, the maximum point, a minimum point, the point of maximum extension, the minimum extension point). Novelty. Theorems for defining the areas of the different behavior of interval functions and terms with various kinds of extreme are proved. Result. We considered in detail and illustrated by example the work of the proposed algorithm of determination for analyzing the behavior of interval functions.
