Estimation computational models of the cyber-physical systems functioning

This paper reviews the use of computational models to support the functioning of cyber-physical systems (CPS) in the parallel world of the Internet of Things (IoT). Existing models, methods, techniques and their implementation in this direction are studied. The necessity of using machine learning methods due to inaccuracy, fuzziness, incompleteness of the transmitted data from sensors of physical systems is substantiated. The task is to make informed decisions in a timely manner to support the functioning of real objects of a particular cyber-physical system in real time conditions

Morphological model for underground crossings of water objects

The construction of morphological model is considered for undesirable events regarding urban objects, as well as the consequences of such events, including interruption of operation, feasibility and time of restoration, material damage and casualties, ecological risks. Using this model, two-stage modified morphological analysis was conducted for two types of objects: pipe and tunnel depressed sewers. The results of comparison for depressed sewer crossings using the developed model are demonstrated both for the whole multitude of potential undesirable events and for the specific scenarios of sabotage, landslide, operational damage. The advantage of a tunneled depressed sewer over a pipe one is justified from the standpoint of minimization of technogenic and ecological risks of sewage draining

Influence of magnetic anisotropy on hysteresis behavior in the two-spin model of a ferro/antiferromagnet bilayer with exchange bias

The influence of magnetic anisotropy of a ferromagnetic film on the phenomenon of exchange bias is studied here. Hysteresis behavior in the two-spin model of a ferro/antiferromagnetic (FM/AFM) bilayer with exchange bias has been investigated in detail. In this model a half-space of an AFM with fixed magnetic configuration comes in contact with a two-layer FM film. Twelve different types of magnetization curves M(H) (both with and without hysteresis) have been found. Some of the M(H) curves demonstrate unusual features, such as plateaus and inclined segments. The hysteresis loop becomes asymmetric if surface anisotropy is taken into account

How do methanol masers manage to appear in the youngest star vicinities and isolated molecular clumps?

General characteristics of methanol (CH3OH) maser emission are summarized. It is shown that methanol maser sources are concentrated in the spiral arms. Most of the methanol maser sources from the Perseus arm are associated with embedded stellar clusters and a considerable portion is situated close to compact HII regions. Almost 1/3 of the Perseus Arm sources lie at the edges of optically identified HII regions which means that massive star formation in the Perseus Arm is to a great extent triggered by local phenomena. A multiline analysis of the methanol masers allows us to determine the physical parameters in the regions of maser formation. Maser modelling shows that class II methanol masers can be pumped by the radiation of the warm dust as well as by free-free emission of a hypercompact region hcHII with a turnover frequency exceeding 100 GHz. Methanol masers of both classes can reside in the vicinity of hcHIIs. Modelling shows that periodic changes of maser fluxes can be reproduced by variations of the dust temperature by a few percent which may be caused by variations in the brightness of the central young stellar object reflecting the character of the accretion process. Sensitive observations have shown that the masers with low flux densities can still have considerable amplification factors. The analysis of class I maser surveys allows us to identify four distinct regimes that differ by the series of their brightest lines.Comment: 8 pages, 4 figures, invited presentation at IAU242 "Astrophysical Masers and their environments

Comparative Analysis of Adolescences, Living in Areas with Different Levels of Urbanization, to Bulling

Исследование буллинга в российской школьной среде проведено в рамках двух методологических подходов: символического интеракционизма, а также психологии и социологии девиантности. Сбор эмпирического материала пилотажного исследования проходил путем применения психолого-педагогической методики "Опросник риска буллинга" (А. А. Бочавер и др.) среди 247 cтаршеклассников Свердловской области.The study of bullying in the Russian school environment was conducted within the framework of two methodological approaches: symbolic interactivityism, as well as psychology and deviance sociology. The empirical material of the pilot study was collected through the use of the psychological and pedagogical method “Bullying Risk Questionnaire” (A. A.

Clinical, hemodynamical and structury-functional correlations in chronic kidney diseases in children

156 children with different kidney chronic disease were examined, including 122 children with chronic pyelonephritis and 34 - chronic glomerulonephritis with nephrotic syndrome. The identified risk factors for the development of nephrological pathology were an unfavorable obstetric and gynecologic anamnesis, occupational hazard and mother’s urogenital pathology, hereditary predisposition and connective tissue dysplasia in the organs and cells. The identified intrarenal blood flow disorders revealed in the form of the intrarenal vascular pattern with a lower blood flow velocity together with tubular and glomerular dysfunction were considered predictors of the developing nephrosclerosis. The morphological characteristic of kidney diseases was presented by signs of pyelonephritis, different morphological variants of glomerulonephritis (prevailing variant was the mesangeoproliferative glomerulonepritis - 69%) and corticomedullary dysplasia with tubulointerstitial component.Обследовано 156 детей с хроническими заболеваниями почек: 122 - с хроническим пиелонефритом, 34 - с нефротическим синдромом хронического гломерулонефрита. Факторами риска развития нефрологической патологии у наблюдаемых детей явились: неблагоприятный акушерско-гинекологический анамнез, профессиональные вредности и урогенитальная патология матерей, наследственная предрасположенность, соединительно-тканная дисплазия на органном, структурном уровнях и их сочетании. Выявленные нарушения внутрипочечного кровотока в виде обеднения интраренального сосудистого рисунка со снижением скоростных показателей в сочетании с тубулярными и гломерулярными дисфункциями следует расценивать как предикторы развивающегося нефросклероза. Морфологическая характеристика заболеваний почек представлена признаками пиелонефрита и различными вариантами гломерулонефрита (преобладал мезангиопролиферативный гломерулонефрит - 69%), кортико-медуллярной дисплазией с тубулоинтерстициальным компонентом
