Authors: Podshivalov I V , Savishnikov M O , Leksikov A A , Dmitriev D D , Kartsan I N 
Published: June 2019

Abstract
A multimode resonator is proposed, containing five resonant modes that are incorporated in the passband forming. The structure is based on a dielectric substrate suspended in a metallic case that allows solving problem of electromagnetic compatibility. Due to features of the resonator’s structure, several higher modes do not excite that significantly improve the performance of the filter’s stopband. The resonator advantages are proved on the ultra-wide bandpass filter (101%) with small overall size (0.11λ
0×0.06λ
0×0.03λ
0) and good stopband performance (first spurious band locates at 8 GHz, suppression is 80 dB).

Authors: Vakhnin A V , Sopov E A , Panfilov I A , Polyakova A S , Kustov D V 
Published: June 2019

Abstract
In fact, many modern real-world optimization problems have the great number of variables (more than 1000), which values should be optimized. These problems have been titled as large-scale global optimization (LSGO) problems. Typical LSGO problems can be formulated as the global optimization of a continuous objective function presented by a computational model of «Black-Box» (BB) type. For the BB optimization problem one can request only input and output values. LSGO problems are the challenge for the majority of evolutionary and metaheuristic algorithms. In this paper, we have described details on a new DECC-RAG algorithm based on a random adaptive grouping (RAG) algorithm for the cooperative coevolution framework and the well-known SaNSDE algorithm. We have tuned the number of subcomponents for RAG algorithm and have demonstrated that the proposed DECC-RAG algorithm outperforms some state-of-the-art algorithms with benchmark problems taken from the IEEE CEC’2010 and CEC’2013 competitions on LSGO.

Published: June 2019

Abstract
This paper presents mathematical models describing extended objects with complex configuration used for planning satellite imagery with optoelectronic scanners of submeter spatial resolution. The most efficient spline approximation methods were used for mathematical description of extended objects with complex configuration. The proposed method ensures obtaining maximum coverage of the extended object in one-orbit period by choosing an appropriate spline smoothing coefficient, shifting and turning coverage contour. The results of computer simulation of extended object imagery are given, taking into account the swath width of the imaging instrument, the required scanning direction and limitations on retargeting angles range and satellite angular velocities.
Ecological and economic efficiency of tillage resource-saving technologies
Authors: Kozhevnikov N V , Zaushintsena A V , Romanov V N 
Published: June 2019

Abstract
Under existing conditions, intensive exploitation of land resources is accompanied by negative changes in agrogenic ecosystems. As a result of the anthropogenic impact on the soil cover, fertility and yield are reduced. To maintain the equilibrium of agrogenic ecosystems from the effects of anthropogenic factors causing soil degradation and loss of its fertility, it is necessary to introduce new technologies that combine safe ecological principles with the production of a stable yield of grain crops. The use of modern technologies of tillage provides the greatest economic effect and is able to increase soil fertility and the level of ecological purity of agricultural products, which is of great importance.

Abstract
The aim of this project is the application of microparticles to a particle of powder which leads to increase the stability of the detergent. Moreover, the idea of the project is to develop a process for coating a powder in a reactor with a continuous flow of reactants through the cooling crystallization, in other words, to change the method of chemical flow process reaction. In this project, the coating process will be illustrated on sodium aluminosilicate (particle core), which will confirm the concept of the powder coating. Moreover, the ultimate goal of this project is to ensure the stabilization of the powder particles (sodium aluminosilicate) with an inorganic coating mixture, where coating material contains a mixture of sodium sulfate and sodium carbonate dissolved in water. In addition, the sub-goal of this project is to investigate the importance of the size of the layer of coated material that needs to be optimized to achieve a desired performance.

Published: June 2019

Abstract
In article research methods of recycling waste. The main selected methods - the development of fertilizers for soils and the creation of innovative building material. Currently, according to the Housing Committee of Administration of St.-Petersburg annually on landfill sites is disposed of 6.5 - 9 million cubic meters per year. Of this volume, only 1.5 million cubic meters (17-23%) is sent for processing in two landfills ("Novoselki" and JSC "Pilot plant MPBO-2 Yanino", project storage tailings according to an approximate assessment have 50 000 tons of RDF-raw materials). Also in St. Petersburg and the adjacent territory of the Leningrad region there are about 250 unauthorized dumps, which are placed, according to very rough estimates, from 500 thousand to 1 million cubic meters of garbage. A distinctive feature of illegal dumps is the high concentration of heavy and rare metals in the garbage. The article discusses the possibility of using aerobic waste composting as a fertilizer for soil and a solid building material, or alternative solid binder, highly abrasive granules. The applied research methods suggest that RDF wastes are commercialized and have the prospect of becoming a separate innovative product.

Published: June 2019

Abstract
The most common method for the production of aluminum products is hot pressing of semi-finished products - aluminum ingots obtained by continuous casting into the mold. This method leads to the formation of a heterogeneous structure. To eliminate this problem, heat treatment is applied, one of which is homogenizing annealing followed by cooling in the chamber. For the study of heat transfer between aluminum ingots and cooling coolant in the chamber, a mathematical model was developed. It showed that the cooling time of ingots in the chamber depends on structural and operational factors. This paper is devoted to the optimization of the design factors of the mathematical model of heat transfer in the cooling chamber of aluminum ingots. The issues of optimization criteria are considered, the objective function is defined with restrictions on the set of feasible solutions of the function.

Authors: Dulesov A S , Karandeev D J , Bazhenov R I , Krasnova T G , Dulesova N V 
Published: June 2019

Abstract
The possibility of applying the information theory in the problem of comparing the expected and statistical probability distribution of failures of a technical system are considered. The paper presents a brief analysis of the processes of additive and multiplicative growth of the system indicators, among which the probability of failure-free operation and failure rate were considered. These indicators were considered in order to analyze the reliability of the system. The increase in reliability of the indicators is associated with the fixing of the failure rate of the system elements and the construction of probability distributions. In order to compare the two distributions, a method for measuring uncertainty is proposed, which includes Shannon’s measure of uncertainty, cross-entropy and Kullback-Leibler divergence. Together, they make it possible to determine the connection between the two different probability distributions of failures, to calculate the distance between the distributions, to identify the degree of difference between the real and desired state of the system during operation. An example of calculation confirming the importance of the participation of the offered method for measuring uncertainty in the problem of comparison of the expected and statistical probability distribution of system failures is given.

Authors: Khazipov M R , Akhmetshin I Z , Pastushenko I L , Sagdeev A A , Galimova A T 
Published: June 2019

Abstract
The process of supercritical fluid extraction recovery of the catalyst at pressures of 10, 20 MPa and temperatures of 343, 373, 433, 473 K with pure supercritical carbon dioxide on the original device has been implemented. An increase in pressure and temperature has a positive effect on the catalyst regeneration process. With increasing pressure increases the density of CO2, and, consequently, its dissolving ability. With increasing temperature, the pressure of saturated vapors of compaction products increases and, as a result, their concentration in CO2 increases. In order to increase the efficiency of the supercritical CO2-extraction process for the regeneration of catalyst samples, carbon dioxide modification with various additives (chloroform, dimethylsulfoxide, acetone, ethanol, and non-polar inert with respect to the catalyst composition hexane) was used. Modification of supercritical carbon dioxide with ethanol and hexane at a temperature of 473 K and a pressure of 20 MPa led to an increase in the mass loss of catalyst samples by 12 and 14%, respectively, which indicate the removal of deactivating substances during regeneration by the method of supercritical fluid extraction.

Investigation of the influence of wind stress in autumn leading to unstable stratification in a meromictic lake using three-dimensional numerical modeling
Authors: Iakubaylik T V 
Published: June 2019

Abstract
Currents in lakes affect the distribution of hydrophysical and hydrobiological characteristics. Three-dimensional model study is an important step toward an improved understanding and reliable prediction of the distribution of hydrophysical fields. Salt stratified lake Shira refers to meromictic reservoirs. The depth of the upper mixed layer depends on many factors (even a few isolated, fairly rare facts of its complete mixing are known). The study of the influence of each of them separately is the task of mathematical modeling. The model results indicate that strong wind stress in the autumn can result in unstable density stratification, leading to intense vertical circulation.
