The largest organ of human body ”skin” is a multilayered organ with complex reflectance properties that not only vary with the direction of illumination but also with the wavelength of light. The complex Three Dimensional (3D) structure and optical properties of human skin makes it very difficult for techniques like Photometric stereo to accurately recover its 3D shape. One problem in particula...

A method of mathematical modeling the ordered surface relief titanium alloy Ti6Al4V after femtosecond laser treatment is proposed, which allowed obtaining informative signs self-organized irregularities, taking into account stochastic and cyclic nature this process. An algorithm has been developed, a package computer programshas created based on proposed model. These methods make it possible to...

Petroglyphs of Karelia are one the most valuable and largest concentrations Rock Art monuments Neolithic hunters-fishermen-gatherers in Northern Europe. The main territory is an integral part historical cultural landscapes preserved from antiquity, which have exceptional attractiveness, originality a certain natural uniqueness. In 2021, petroglyphs were included UNESCO list, they became first m...

Abstract. The paper discusses a problem of complex data application when accounting erosion network elements to study soil runoff and material redistribution on arable slopes. It is needed estimate account contribution microrelief landforms the sediment (washed out material) areas enhance accuracy estimation accumulation. However, are hardly detected topographic maps plans used traditionally in...

The article presents the results of analysis modern literature sources in search mathematical models describing dynamics process forming regular microrelief on inner cylindrical surfaces parts operating difficult conditions, order to increase their life cycle. absence this and peculiarities its implementation with point action deforming element surface body part are established. movements tool ...

The structural and gas-sensitive properties of n-N SnO2/κ(ε)-Ga2O3:Sn heterostructures were investigated in detail for the first time. κ(ε)-Ga2O3:Sn SnO2 films grown by halide vapor phase epitaxy high-frequency magnetron sputtering, respectively. gas sensor response speed operation structures under H2 exposure exceeded corresponding values single within temperature range 25–175 °C. Meanwhile, d...
