Models of assessment of the influence of insurance assets securitization on stability of mutual insurance societies

The article reviews approaches to assessing the effectiveness of the mechanism of insurance assets securitization used to enhance the financial stability of the mutual insurance society, determined by the level of probability of its default. The approaches are based on the methods of simulation modeling of the financial flows of the society formed taking into account the patterns of random payments, deterministic premiums, proceeds and securitization costs. Following the results of a series of simulation experiments, the peculiarities of the influence of securitization on stability of a MIS are identified, and recommendations for its use are justified. The estimates of the costs of structuring the transaction are obtained, based on which a certain minimum volumes of securitization are determined, at which its use is appropriate.peer-reviewe

Radish Productivity Under Inclusion of Plant Inedible Biomass in Mass Exchange Processes of a Biological-Technical Life Support System

Использование почвоподобного субстрата (ППС) в качестве корнеобитаемого субстрата является одним из перспективных способов культивирования растений в биолого-технических системах жизнеобеспечения (БТСЖО). Возможным способом увеличения степени замкнутости массообменных процессов в БТСЖО длительного срока функционирования служит вовлечение в массообменные процессы несъедобной растительной биомассы. В статье приводятся результаты оценки трех способов минерализации несъедобной биомассы пшеницы и редиса: «биологический», физико-химический и комбинированный. «Биологический» способ осуществляли путем внесения сухой несъедобной биомассы пшеницы и редиса в ППС, который служил корнеобитаемой средой и биореактором для разложения растительных отходов. Физико-химический способ основан на методе «мокрого» сжигания несъедобной биомассы пшеницы и редиса перекисью водорода в переменном электромагнитном поле с последующим внесением полученного раствора в поливной раствор. Комбинированный способ включал в себя внесение физико-химически минерализованной пшеничной соломы в поливной раствор, а несъедобной биомассы редиса непосредственно в ППС. Состояние растений редиса оценивали по состоянию фотосинтетического аппарата, по показателям СО2 газообмена комплекса «ценоз редиса – ППС», по продуктивности и другим физиологическим характеристикам. Из исследованных способов минерализации оптимальным оказалось комбинирование физико- химической минерализации соломы пшеницы и «биологического» метода минерализации несъедобной биомассы редисаUse of the soil-like substrate (SLS) as a root-inhabited substrate is one of the most perspective ways of plants cultivation in biological-technical life support systems (BTLSS). Inclusion of plant inedible biomass seems to be necessary for closure increase of mass exchange processes of a long-functioning BTLSS. The work presents estimation data of three ways of processing wheat and radish inedible biomass introduced into the SLS: a ‘biological’ method, a physical-technical way and a combined one. Radish (Raphanus sativus L.) “Mokhovsky” variety was a test culture. The ‘biological’ method represented the SLS used as a bioreactor in which dry wheat and radish inedible biomass was introduced. The physical-technical method consisted of ‘wet’ oxidation of wheat and radish inedible biomass by hydrogen peroxide in alternating current with further introduction of the solution obtained into the solution for plants irrigation. The combined method included physical-chemical mineralization of wheat straw and radish inedible biomass introduced directly into the SLS. The combined method consisted of the physical-chemical oxidation of wheat straw and the ‘biological’ processing of radish inedible biomass appeared to be the most optimal way from all methods under stud

On subgroups of minimal topological groups

A topological group is minimal if it does not admit a strictly coarser Hausdorff group topology. The Roelcke uniformity (or lower uniformity) on a topological group is the greatest lower bound of the left and right uniformities. A group is Roelcke-precompact if it is precompact with respect to the Roelcke uniformity. Many naturally arising non-Abelian topological groups are Roelcke-precompact and hence have a natural compactification. We use such compactifications to prove that some groups of isometries are minimal. In particular, if U_1 is the Urysohn universal metric space of diameter 1, the group Iso(U_1) of all self-isometries of U_1 is Roelcke-precompact, topologically simple and minimal. We also show that every topological group is a subgroup of a minimal topologically simple Roelcke-precompact group of the form Iso(M), where M is an appropriate non-separable version of the Urysohn space.Comment: To appear in Topology and its Applications. 39 page

Hybrid tracking detector based on semiconductor and gas technologies

New Silicon-Gas Pixel Detector (SiGPD) is the result of the further development already proposed Gas-Pixel Detector (GPD). The only disadvantage of GPD was the uncertainty of the particle arriving time. The problem can be solved by additional silicon pixels implementation inside existed electronic chip epitaxial layer during regular chip production. The cost of new Si-Gas Pixel Detector remains practically the same. The new detectors have self-triggering properties and can be used for a first level trigger generation in the particle physics experiments and for many other applications

On Exact Values of n-Widths in a Hilbert Space

AbstractThe exact values of Kolmogorov n-widths have been calculated for two basic classes of functions. They are, on the one hand, classes of real functions defined by variation diminishing kernels and similar classes of analytic functions, and, on the other hand, classes of functions in a Hilbert space which are elliptical cylinders or generalized octahedra. This second case is surveyed and new results are presented. For n-widths of ellipsoids, elliptic cylinders, and generalized octahedra, upper bounds for the n-widths are based on the Fourier method. The lower bounds are based on the method of “embedded balls” for ellipsoids and the method of averaging for generalized octahedra. General theorems concerning elliptical cylinders and generalized octahedra are proved, various corollaries from these general theorems are considered, and some additional problems (average n-widths, extremal spaces for an ellipsoids and octahedra, etc.) are discussed

Geant4 simulation model of electromagnetic processes in oriented crystals for the accelerator physics

Electromagnetic processes of charged particles interaction with oriented crystals provide a wide variety of innovative applications such as beam steering, crystal-based extraction/collimation of leptons and hadrons in an accelerator, a fixed-target experiment on magnetic and electric dipole moment measurement, X-ray and gamma radiation source for radiotherapy and nuclear physics and a positron source for lepton and muon colliders, a compact crystalline calorimeter as well as plasma acceleration in the crystal media. One of the main challenges is to develop an up-to-date, universal and fast simulation tool to simulate these applications. We present a new simulation model of electromagnetic processes in oriented crystals implemented into Geant4, which is a toolkit for the simulation of the passage of particles through matter. We validate the model with the experimental data as well as discuss the advantages and perspectives of this model for the applications of oriented crystals mentioned above.Comment: 18 pages, 9 figure

Innovation Clusters: Advantages and Disadvantages

The main direction of the current economic development is found in a transition of the most civilized countries to a new stage of creating an innovative society, i.e. building the economy based mainly on offering, spreading and using of knowledge. The specific functioning of innovation clusters allowing to create new technologies, implement deep technological modernization and innovative industry development based on personal or adopt technologies, as well as to train personnel for work in the conditions of the current industrial and technological formation, is characterized by the three components: the fundamental, practice-oriented science, innovative industry, and developing education. Along with that, nowadays there is a need to take firm measures not only to revive the innovative activity, but also to make a breakthrough in this area. Therefore, it is necessary to provide the state-of-the-art mechanisms to increase the innovative activity of domestic high-tech innovative economy based on the cluster approach, cluster initiatives.
