In a market economy, the competitiveness of an enterprise is ensured by the introduction of innovations. In order to remain innovative, enterprises need high-quality human resources. Investments in human resources, as the main factor of innovative growth, determine the ability of employees to transform their existing knowledge, skills and abilities into high-tech products, highly qualified services.

In analytical form, the peculiarities of forming Fraunhofer diffraction patterns and images of faces of a volumetric asymmetric edge of an object with an absolutely reflective internal surface in relation to dimensional inspection were investigated. Formulas were obtained for calculating fields in diffraction-limited systems depending on the magnitude of the bevel of the object c , the phase shift j of the wave reflected from the inner surface of the object, and the angular aperture of the coherent optical system for forming and filtering images. It has been established that for metal 3D-objects (j = p), the value of the field in the image of the back face at a point, corresponding to the position of its border is negligible with the depth of focus of the system much less than the thickness of the object. It is shown that when bevels of an object, much less than the size of the Fresnel zone d ~ ( l - wavelength of light, d - thickness of the object) and more than the depth of focus, the displacement of the intensity profile in the image of the front face is proportional and depends on the angle j. With large bevels, when and, the displacement of the front face boundary is inversely proportional to the value. These displacements can lead to systematic errors in measuring the position of the boundaries of the faces of a 3D-object and should be taken into account in precision dimensional inspection.

The problem of achromatization of a single volume holographic element is solved in this work by choosing the dispersion coefficients of the material at the stages of recording and use. The condition for achromatization of a single volume holographic element was obtained in this work, namely, the difference in the dispersion coefficients of this element at the stages of use and recording should be inversely proportional to the recording wavelength.

This paper presents the results of a study of direct laser writing on thin films of transition metals (Hf, Ti, Zr, Ta, V). The films were deposited on fused silica substrates. A comparison of laser writing on the indicated films is carried out from the point of view of the presence of contour writing. As it was proved earlier, when writing on zirconium films, contour writing leads to formation of periodic nanostructures with a period equal to the writing step (250-500 nm). Materials were identified that are promising from the point of view of writing oxide nanostructures for the further formation of the diffraction phase microrelief of DOEs.

The paper deals with issues of object detection in conditions of smoke, dust curtains and fog in the IR-THz ranges of electromagnetic wavelengths. It is shown that remote detection of objects and determination of their movement direction under conditions of real interference in the atmosphere is provided with high accuracy and reliability in the IR-THz ranges. The results of experimental measurements and the performed calculations show that to reduce the attenuation of the signal received from the object under conditions of smoke, dust curtains and fog, it is necessary to use IR and THz methods together.

Students’ physical quality “jumping" in non-physical education university is discussed in the article. Complementary characteristics of "jumping ability" described by scientists in different years are given and literary sources of scientists on this problem are analyzed. The article provides the results of practical research based on the Abalakov’s test for measuring jumping ability among students at elective physical culture lessons and a comparative analysis of the test results is presented. Sport that shows the highest jumping ability as an important component of harmony in human motor actions is revealed. Activities at University sports clubs are recommended.

Non-structural traps and reservoir flanks are characterized by angular unconformities. Angular unconformity between dipping formation and sub-horizontal oil-water contact is common in the North Sea fields. This paper presents an approach to real-time inversion of LWD resistivity data for the scenario with angular unconformity. The approach utilizes artificial neural networks (ANNs) for calculating the tool responses in parametric surface-based 2D resistivity models. We propose a parametric model with two non-parallel boundaries suitable for scenarios with angular unconformity and pinch-out. Training of ANNs for this parametric model is performed using a database containing samples with the model parameters and corresponding tool responses. ANNs are the kernel of 2D inversion based on the Levenberg-Marquardt optimization method. To demonstrate applicability of our approach and compare with the results of 1D inversion, we analyze Extra Deep Azimuthal Resistivity tool responses in a 2D synthetic model. It is shown that 1D inversion determines either the position of the oil-water contact or dipping layers structure. At the same time, 2D inversion makes it possible to correctly reconstruct the positions of non-parallel boundaries. Performance of 2D inversion based on ANNs is suitable for real-time applications.
