The System of Temperature Control in a Magnetotherapy

The article is devoted to the issue of the temperature control of a biological object in the magnetotherapy. We develop the mathematical model of the magnetic field influence on a biological object with the control of the temperature variation on the surface epidermis areas. We conduct an experimental research of temperature variation of a biological object with magnetotherapy apparatuses “MIT-11” and “POLUS-4”.

Formation of the Model Structure of Assembly Products in Instrument-Making

The paper deals with the specific nature of assembly processes in instrument-making and considers the current state of development of computer-aided design technology assembly and their suitability for conditions of instrument-making production. In addition, we develop the mathematical model of the assembly product in instrument-making taking into account complexity and specificity of the assembly, adjustment and test work.

Temperature Influence on Aberration Properties of Infra-Red Lenses

This paper considers temperature influence on image quality of focusing systems operating in an infra-red spectral range for the case of homogeneous temperature distribution. Using the optical design programs it is possible to estimate the influence of temperature on optical descriptions of depicting systems operating under unstable temperature conditions. The article elucidates the results of temperature influence analysis on aberration properties of non-athermalized and athermalized infra-red lenses.

The Model of Optical Radiation Propagation in Tissue

The paper shows the relevance of developing the model of optical radiation propagation in tissue that will further implementatation of calculation engineering methods of optical radiation intensity distribution in tissues for surgical intervention or therapeutic effect. We propose the so called “three pulse” model of optical radiation propagation in tissue and method based on it. To calculate the coefficients of the model basic expression, we develop the three equation system. These equations describe the boundary conditions of optical radiation propagation in tissue.

Investigation of Kinoform Element Chromatism

The paper investigates the chromatic characteristic of the kinoform element in a given spectral range. Based on the well-known chromatism theory we obtain more exact expressions of the chromatic focus shift and the dispersion coefficient. The enhanced chromatism theory determined that the chromatic focus shift and the dispersion coefficient depend not only on a spectral range but also on a Fresnel zone number. Based on the enahnced theory we analyze the kinoform chromatism in the spectral range of 8–12 µm.

Methodology and Device for Monitoring and Control of Polarization Changes Behavior of Stratosphere Ozone Layer-Reflected Solar Radiation

The purpose of this paper is to choose the method and to create the device to control the condition of radiation polarization reflected from an ozone layer of the Earth stratosphere from a microsatellite board. We consider the research-related issues, as well as the algorithm and the organization of the space experiment. We conclude that it is possible to use the ultraviolet Stokes-polarimetry as the method for space Earth’s ozone layer monitoring. It allows accessing the data on the solar radiation scattered by the stratosphere.

Performance Evaluation for Multichannel Optoelectronic Surveillance Systems (MOESS) with Image Fusion

The article proposes the methodology for performance evaluation of MOESS with image fusion. This methodology combines probability of detection, recognition and identification with image fusion quality metric – targeting task performance. This metric takes into account the image formation process in single channel of MOESS, image fusion and human visual perception. Simulation results are well correlated with subjective tests. The proposed methodology allows matching the best image fusion method for current operating conditions.

Development of Quality Criterion of Spot Welding by Results of Acoustic Emission Monitoring

This article discusses the design of algorithm for processing of acoustic emission signals. It will allow elaborating the criteria for assessing the quality of resistance spot connection. The problem can be solved by using the convolution method, which can detect the exemplary temporal process in the analyzed signal. We synthesize two processing algorithms of acoustic emission signals by using linear and nonlinear transformations.
