FREQUENCY-INDEPENDENT LIMITS OF VALUES OF SYSTEM PARAMETERS OF CELLULAR COMMUNICATIONS AT MULTIPATH PROPAGATION OF RADIO WAVES IN URBAN AREA
Authors: Mordachev V. I.
Published: December 2019

The analysis was carried out in order to clarify the estimates of the expected restrictions on characteristics of new-generation mobile communications (4G, 5G) under the existing restrictions on radiated power of subscriber radio equipment, as well as in conditions where the boundaries of urban sites are outside of the area of free radio waves propagation (RWP) between subscriber and base stations. Analysis was performed using the basic principles and ensemble models of statistical theory of electromagnetic environment, as well as the basic principles of information theory that determines the radio channel capacity in presence of interference. Frequency-independent relationships have been obtained for estimating a number of system parameters of cellular communications under the conditions of multipath RWP in urban canyons and the presence of internal system interference: estimation the required equivalent isotropic radiated power (EIRP) of subscriber stations, the maximum data transmission capacity of the backward radio channel, the maximum distance of qualitative communication, and also the permissible level of internal radio interference at given requirements for communication range, and the information transfer rate of reverse radio channel taking into account the accepted restrictions on EIRP of subscriber radio equipment. The obtained relations allowus to estimate the limits of possible values of these system parameters of modern and future mobile communications; these relations also provide the opportunity to justify the quality requirements for ensuring the intra-system electromagnetic compatibility at the required data rate in backward radio channels of cellular networks and the existing restrictions on EIRP of subscriber stations.

Authors: Smorodin V. S. , Prokhorenko V. A.
Published: December 2019

In this paper authors present the results of a research that had a purpose to develop a method of constructing a neuroregulator model for the case of optimization of the control structure of a technological cycle. The method's implementation is based upon the automation of a production process when a physical controller, that operates the technological process according to a given program, is present. In order to achieve this goal, the artificial neural network approaches were implemented to create a mathematical model of the neuroregulator. The mathematical model of the neuroregulator is based on a physical prototype, and the procedure of a real-time control synthesis (adaptive control) is based on recurrent neural network training. The neural network architecture includes LSTM blocks, which are capable of storing information for long periods of time. A method is proposed for constructing a neuroregulator model for control of a production cycle when solving the task of the optimal trajectory finding on the phase plane of the technological cycle states. In the considered task of the optimal trajectory finding the mathematical model of the neuroregulator receives at each moment of time information about the current system state, the adjacent system states and the movement direction on the phase plane of states. Movement direction is determined by the given control optimization criteria. Based on the research results it was found that recurrent networks with LSTM modules can be used successfully as an approximator for the agent's Q-function to solve the given problem when the partially observed region of system states has a complex structure. The choice of the method of adaptation to the control actions and the external environmental disturbances proposed in the paper satisfies the requirements for the adatation process performance, as well as the requierments for the control processes quality, when there is lack of information about the nature of random control disturbances. The experimental environment, as well as the neural network models was implemented using the Python programming language with TensorFlow library.

Authors: Holdman Y. I. , Titovich E. V.
Published: December 2019

The rapid development of technologies in the field of radiation therapy allows us nowadays to implement precision and most clinically effective radiotherapy techniques for oncological patient’s treatment to minimize the irradiation of normal tissues and improve local tumor control. An important condition for the implementation of the justification principle is strict compliance with the requirements for the accuracy of the dose delivered. High standards of radiation treatments performed are guaranteed by the development and strict compliance with the quality assurance (QA) program in the radiological department. However, due to QA programmes specificity, standardized and worldwide used tests included in the quality management system are trivial mechanical and dosimetric tests that can’t define the presence and magnitude of the integral error in the dose delivered to the patient, which arises as a result of the execution of sophisticated radiation therapy procedures, as well as to take into account the complexity of the implementation of modern methods of treatment. The aim of the work is to develop a method of complex dosimetric testing of the radiation therapy process (end-to-end audit), based on the utilization of the anthropomorphic phantom of the original design. The result of this work is the creation of the modified anthropomorphic phantom for precision dosimetric measurements, designed for testing the following technological procedures of the radiation therapy process: a computer tomography acquisition; a computerized treatment planning system, including a contouring module and dose distribution calculation algorithm; imaging systems integrated with radiation treatment units; dosimetric and technical characteristics of the radiation treatment units. Regular dosimetric testing of the radiation therapy technological process (end-to-end audit) with utilization of the technique proposed by the authors, based on the developed anthropomorphic phantom usage, will allow to assess the accuracy of dose distribution delivered to patients with all major malignant tumors localizations.

Published: December 2019

A study of the influence of the formation regimes of avalanche LEDs based on nanostructured silicon on the parameters of the formed devices, such as the light emission voltage and the stability of operation has been performed. These parameters are an important factor for the practical use of avalanche LEDs in the development of silicon photonics products, the progress of which is associated with the future of integrated electronics. For the first time, the technological operation of local through electrochemical anodizing of aluminum in various electrolytes for the formation of a separating dielectric of Schottky contacts is presented. The influence of the built-in electric charge in the separation dielectric of silicon avalanche LEDs on their current-voltage characteristics is studied. It was found that the built-in negative electric charge increases the breakdown voltage of the Schottky contact, which results in an increase of the light emission efficiency of the diode structures. An explanation of this effect is presented on the basis that the built-in negative electric charge inside the anode oxide also creates a space charge region in silicon, which helps to reduce the effect of the concentration of field lines at the edges of diode structures, performing the function of protecting the Schottky contact from edge effects as well as protective areas do. It has been established that the highest avalanche breakdown voltage is observed in diode structures with anodic oxide formed in an electrolyte based on an aqueous solution of phosphoric acid. An analysis of the characteristics of LEDs at different temperatures of silicon substrates showed an increase of breakdown voltage with increasing temperature, which is typical for avalanche breakdown during impact ionization. Stable light emission of the formed LEDs was demonstrated in a wide range of operating voltages (8–16 V). The use of silicon avalanche LEDs both as discrete devices and in integrated electronics in general has been discussed.

Published: December 2019

The article presents the results of preliminary research in the wideband transformer development for matching low-ohms loads in the very high frequency band with the use of a coupled transmission lines. The transmission line was produced with the using of a polyimide in the form of flexible printed circuit board. This way may be useful for wideband matching different cascades with custom values of input and output impedance in the wide band of frequencies and powers with use of a defining impedance capability with a load character in mind. On the first stage, the computer simulation of transformer with a transformer ratio 4:1 in the band (40–240 MHz) was completed for limiting values of input and output resistances – 50 and 12,5 Ohms respectively. Results of simulation give us the data about constructive parameters of the transmission line. The measurement technique for insertion loss was worked out. The reason of that is an impossibility of appliance standard methods with using a network vector analyzer. The prototyping was done and values of the standing wave ratio and inserting losses were obtained for different levels of the input power. According to received data, it can be affirmed, that the manufactured transformer provides the standing wave ratio better (lower) that two. Inserting losses vary from 0,02 to 1,54 dB depending from a input power level (1– 1000 mW). The obtained results afford ground for working continuation in this field – a development of wideband transformers for matching of low-ohms loads.

Authors: Yurtsev O. A. , Popov A. A.
Published: December 2019

The aim of the work is to determine the properties of the ultra-wideband scanning antenna array of wire emitters. A single element of the grid is a three-dimensional antenna Vivaldi. Numerical simulation of antenna arrays and single Vivaldi emitters was carried out by the method of integral equations in the thin-wire approximation using the original program and the MMANA program. The dimensions of all elements of a single emitter are determined by the criterion of matching and the shape of the radiation pattern for operation in the frequency range 2–18 GHz. The described variant of the antenna according to the matching criterion (SWR < 2) has a frequency overlap coefficient of 12. The narrowing of the frequency band of a single emitter in the composition of non-scanning and scanning gratings within the angle of 30 degrees is determined. The article deals with the range properties of antenna arrays depending on the parameters of the emitters and the possibility of phase scanning. It is shown that the greatest frequency band in agreement has a lattice with a minimum step of placement of emitters. In a flat antenna array, when scanning in the H-plane, the frequency band according to the matching criterion decreases by 2–3 times. It is shown that the linear lattice without scanning has a frequency overlap coefficient equal to 6 according to the criterion of matching emitters. This ratio decreases as the phase scan sector increases. In a flat lattice, the frequency overlap coefficient and the phase scan sector are smaller than in a linear lattice and decrease with the number of rows. The reduced antenna array has a number of design advantages and can be used in systems with ultra-wideband signals.

Authors: Butov A. A.
Published: December 2019

The technological process of manufacturing ultra-large integrated circuits includes a number of stages, one of which is the preparation with the help of computer-aided design of input information for the image generator photodetector. Creating a control program for image generation generates a large number of problems, many of which are solved by methods of computational geometry and usually operate with geometric objects such as polygon or rectangle. The purpose of this work was to develop methods for performing a set-theoretic intersection operation on topological objects of the polygon type. The paper analyzes the different variants of the intersection of the sides of polygons with each other and introduces the concept of degenerate and possible intersection points. The rules are formulated to identify degenerate points of intersection of the sides of polygons in order to reduce the number of fragments into which the boundaries of polygons are divided by intersection points, as well as to clarify the status of possible intersection points. Two methods of finding the intersection of polygons are proposed: a simpler basic method, applicable to a wide range of practical problems, and a more complex General method, used in practice much less often. The material of the article relates to research related to the General task of developing a software system for the preparation of topological information for microphotoset image generators.

The kinetics of phase contents modification in the process of SrBaFeMoO6–δ crystallization from a stoichiometric mixture of SrCO3 + BaCO3 + 0,5Fe2O3 + MoO3 simple oxides using the solid phase method has been investigated. In the temperature region of 300–1200°С, a number of endotermic effects have been detected. Herewith, the first one (with maximum around 552°С) and the third one (with maximum around 743°С) are accompanying by the significant decrease of the mass of specimen. In the temperature range of 946–1200°С, the mass change of specimen is practically not observable, while the thermal effect is still present, and the specimen remains not single-phase one. This indicates the difficulty of the flow of solid phase reactions with the formation of solid solution of barium-strontium ferromolybdate. During analysis of the change of the phase composition consisting of a mixture of initial reagents of stoichiometric relation SrCO3 + BaCO3 + 0,5Fe2O3 + MoO3, it has been observed that with increasing temperature, complex compounds BaMoO4, SrFeO3 appear almost simultaneously, then SrBaFeMoO6–δ appears consequently. Thus, the compounds BaMoO4 и SrFeO3, are structure forming for the solid solution of barium-strontium ferromolybdate. With further temperature increase up to 770°С the formation of new compound ВаFeO3 with disappearing SrFeO3 was detected. In this case, the amount of double perovskite increases faster than that of barium molybdate. The main accompanying compounds at the crystallization of the SrBaFeMoO6–δ double perovskite solid solution are BaMoO4 and SrFeO3. It was established that at the initial stage of the interaction, the resulting solid solution of barium-strontium ferromolybdate is enriched with iron and its composition changes during the reaction in the direction of an increase of the molybdenum content, as in the case of other precursor combinations.
ON THE PROBLEMS OF BILEVEL OPTIMIZATION UNDER RCPLD CONSTRAINT QUALIFICATIONS
Authors: Minchenko L. I. , Sirotko S. I.
Published: December 2019

Multilevel optimization problems often arise in various applications (in economics, ecology, power engineering and other areas) when modeling complex systems with a hierarchical structure associated with independent actions of subsystems. The difficulty of analyzing such complex systems requires first of all the study of bilevel models, the management of which would be an integral part of the analysis of more complex systems. In solving bilevel programming problems, an important role is played by the property of partial calmness, the presence of which allows us to reduce the bilevel problem to the classical nonlinear programming problem with a nonsmooth objective function. It is known that linear bilevel programming problems are partially stable. The proof of this property for more complex problems meets difficulties. In particular, our article shows the inaccuracy of some results in this area. The goal of the paper is to obtain some new results in the partial calmness of bilevel programming. In particular, new sufficient conditions for bilevel problems are proved. The results are obtained on the base of Lipschitz-like properties for multivalued mappings. In the paper we propose new sufficient conditions for partial calmness which are based on some modification of the known constraint qualification RCPLD which have been proposed by the researches Andreani, Haeser, Schuverdt and Silva.

The aim of the work, the results of which are presented in the framework of the article, was to study the of electromagnetic radiation interaction laws in the frequency range 0.7…17 GHz with two-layer structures, the surface layer of which was made using powdered titanium dioxide, and the inner layer was made using a powder material based on oxide ferric iron. The thickness of the layers of the studied structures varied from 0.3 to 1 cm. To achieve this goal, theobjectives associated with the development of a methodology for the manufacture of multilayer structures based on composite materials containing transition metal oxides, as well as with the measurement of such structures samples electromagnetic radiation reflection and transmission coefficients in the frequency range 0.7...17 GHz. These measurements were carried out using a panoramic meter of reflection and transmission coefficients SNA 0.01–17. Based on the obtained measurement results, it was shown that in the frequency range 0.7…2 GHz, the lowest values of electromagnetic radiation reflection coefficient, reaching –20 dB, are characterized by structures whose surface layer thickness is 1 cm, and in the range 2 ... 17 GHz – structures, thickness the surface layer of which is 0.5 or 1 cm (depending on the thickness of the inner layer). The values of electromagnetic radiation transmission coefficient in the frequency range of 0.7...17 GHz of such structures reach –23 dB. Based on the results of the study, it is proposed to use the considered structures in the process of creating shielded rooms or improving the latter (for example, in cases, when it's necessary to reduce the level of passive interference in rooms shielded with metal materials).

Generally children spend time playing and trying new things. Not infrequently they play and satisfy their curiosity through gadgets, because gadgets are an interesting tool, children should still spend more time playing with peers. The development of gadgets is very influential in the development of human life. This phenomenon is most easily found in children who come from families where gadgets are no longer a luxury item for them. So parents have to control children who use gadgets. There are certain hours a child holds a cellphone, there are certain hours a child with parents. One negative impact of the use of gadgets on children include: 1) being private closed, 2) impaired brain health, 3) impaired eye health, 4) impaired hand health, 5) sleep disturbances, 6) aloofness, 7) violent behavior, 8) fading creativity, 9) radiation exposure, and 10) cyberbullying threats. The most influential figure in preventing or overcoming the negative effects of gadgets are parents. So parents have a big role in guiding and preventing gadget technology from having a negative impact on children. Ways that must be done by parents are as follows: 1) select according to the age of the child, 2) Be selective in choosing the game application in the gadget, 3) Accompany children in playing, 4) Limit the time playing gadget for children, and 5) Invite children to do positive activities.

Authors: Paulina Yanti , Kusmiarti Reni
Published: January 2020

Bahasa Serawai masih banyak dipakai oleh masyarakat yang tinggal di kabupaten Bengkulu selatan. Meskipun bahasa serawai adalah bahasa yang masih banyak penuturnya, ada kekhawatiran akan makin berkurangnya pemakai bahasa ini. Kekhawatiran itu bukan hanya dipengaruhi oleh faktor-faktor eksternal seperti pengaruh bahasa Indonesia melainkan juga oleh faktor internal, seperti adanya undak usuk bahasa yang menyebabkan banyak keluarga yang tidak mau lagi menggunakan bahasa Serawai di dalam keluarganya, bahkan termasuk keluarga suami dari suku Serawai dan Istri dari suku Serawai juga ( selanjutnya disebut Keluarga Serawai-Serawai).Keluarga yang sudah tidak setia lagi dengan bahasa Serawai ini kemudian beralih kebahasa Indonesia dengan berbagai alasan. Dengan demikian telah terjadi pergeseran bahasa ( language shifting).Masalah dalam penelitian ini adalah:1) Apakah telah terjadi pergeseran bahasa pada  keluarga suku Serawai-Serawai di Kota Bengkulu? 2) Jika benar telah terjadi pergeseran bahasa seberapa besar pergeseren bahasa telah terjadi? 3) Bagaimana sikap bahasa terhadap bahasa serawai pada  keluarga suku Serawai-Serawai di Kota BengkuluTujuan penelitian ini adalah untuk mendeskripsikan  : 1) Pergeseran bahasa pada  keluarga suku Serawai-Serawai di Kota Bengkulu 2) Seberapa besar pergeseren bahasa telah terjadi 3) Sikap bahasa terhadap  bahasa serawai pada keluarga suku Serawai-Serawai di Kota Bengkulu.Metode penelitian dalam penelitian ini dengan metode deskriptif. Teknik pengumpulan data dengan menggunakan Angket ( kuesioner) yang diberikan kepada keluarga yang suami dan istrinya berasal dari suku serawai yang tinggal di kota Bengkulu.Kesimpulan dari hasil penelitian ini adalah :1)Telah terjadi pergeseran bahasa pada  keluarga suku Serawai-Serawai di Kota Bengkulu. Pergeseran bahasa terlihat dari hasil perunutan dari generasi pertama (kakek)100 % menguasai bahasa Serawai, lalu generasi ke dua (orang tua) 84 dan 70 % menguasai bahasa Serawai, kemudian  generasi  ketiga (anak) memperlihatkan penurunan angka  tinggal 20 % menguasai bahasa Serawai. 2) Sikap bahasa terhadap bahasa serawai pada  keluarga suku Serawai-Serawai di Kota Bengkulu adalah kurang (Negatif), karena dari hasil presentase yang diperoleh jumlah hasil  sikap bahasa pada keluarga suku Serawai-Serawai adalah 20 %. Apabila merujuk pada tabel skala sikap berada pada rentang 20-39 dengan kreteria kurang (negatip),berarti keluarga suku serawai-serawai kurang memiliki rasa kebanggaan atau kesetiaan lagi terhadap bahasa serawai.
Una mirada a la resiliencia urbana y social de la ciudad de Portoviejo post terremoto.
Authors: Moretta Macias Betsy María
Published: December 2019

El presente estudio tiene como objetivo identificar y analizar cuáles son los factores históricos, físicos, socio-económicos y, políticos que inciden en la  recuperación urbana-social del centro histórico y comercial de la ciudad de Portoviejo, post terremoto del 16 de abril de 2016, se realizó una revisión documental, trabajo de campo  y grupos focales, con el fin de entender cuáles son los efectos sociales y espaciales que provocó el terremoto; y, cual es la percepción de la comunidad respecto a las actuaciones y proyectos futuros, para así plantear estrategias que fomenten la resiliencia de la ciudad. Desde el estudio realizado se puede concluir que Portoviejo es una ciudad inscrita en el riesgo y la vulnerabilidad, la mayoría de las edificaciones que colapsaron fueron las que no poseían una correcta estructura, por lo que las nuevas edificaciones deben cumplir con las normas técnicas sismos resistentes. Los planes habitacionales post-terremoto han generado segregación; así mismo, faltan por ejecutar proyectos de reactivación en el centro comercial de la ciudad que es uno de los ejes motores de la misma. La clave para construir ciudades resilientes se centra en la planificación territorial donde la prioridad debe ser la sociedad.

Authors: Jiménez Enrique Félix , García Muñoz Aparicio Cecilia , Ancona Alcocer María Del Carmen
Published: December 2019

El propósito de esta investigación fue identificar el capital intelectual de una consultoría de negocios para reconocer el valor de la misma en el mercado de las asesorías o consultas en las empresas, derivadas del conocimiento, determinando los elementos del costo tradicional: mano de obra, materia prima y gastos indirectos. Se utilizó una metodología de tipo transversal, donde se recolectaron datos en un solo momento y tiempo, con un modelo mixto integrando el enfoque cualitativo y cuantitativo. Se concluye que en el segmento de la contabilidad no se dimensiona lo valioso que es el capital intelectual sin estimar lo que representa para el negocio. Una línea futura de investigación es integrar el costo del capital intelectual en la Contabilidad.

Authors: Alfonso Alfonso Rodney , Ulacia Oviedo Zoila De las Mercedes , Suárez Mella Rogelio Pedro
Published: December 2019

El presente trabajo presenta una propuesta de ejes estratégicos para el uso y aprovechamiento de las Tecnologías de la Información y Comunicaciones (TICs), en hoteles de categoría tres y cuatro estrellas, como componente asociado a la innovación tecnológica. Se tomó una muestra de 16 hoteles con destinos en ciudades de Cuba y Ecuador. La investigación se inició con una etapa de consulta documental y bibliográfica acerca de la aplicación de las TICs, en el contexto hotelero internacional y las normas de alojamiento de ambos países. Seguido, se determinó la brecha existente entre la muestra de estudio y la práctica hotelera internacional, la cual no es significativa, debido al uso en gran parte de las aplicaciones. En la segunda etapa se estudiaron las potencialidades de las TICs relacionadas con: la atención, aprovechamiento e importancia para los clientes. Se constató que las redes sociales, páginas web y redes inalámbricas son las que más deben aprovecharse. Finalmente, se propone la utilización de tres ejes, junto a programas asociados y relacionados con la incorporación de herramientas y aplicaciones tecnológicas de gestión hotelera, inversión en infraestructura de este tipo y la profundización en conocimientos asociados a las TICs para la atención a clientes.

Optimal operation of battery for wind-storage hybrid power plant
Authors: Das Kaushik , Grapperon Anatole Louis Theodore Philippe , Sørensen Poul Ejnar , Hansen Anca Daniela
Published: December 2019

In order to participate in energy market, variable renewable energy sources need to reduce the uncertainty of forecast errors. Inclusion of storage can be a viable option not only to minimize the penalties due to forecast uncertainties but also to maximize the revenue generation. This paper presents a

decision framework for respecting the market constraints and maximise the revenues of a wind and storage power plant. Wind power and price forecast are used in convex optimisation algorithm for making day ahead decisions on battery operation. This day ahead optimisation results feed to an algorithm for operating in the balancing market. Several scenarios and case studies have been simulated to assess the value of storage for revenue maximization of a wind power plant. The results show that proposed algorithms can increase the revenue by more than 10% compared to the operation of wind power plant without battery.

Published: December 2019

Предложен метод получения порошков оксинитрида алюминия (AlON), которые могут быть использованы в качестве матрицы при создании композиционных материалов. Метод заключается в азотировании смеси Al/Al2O3 под высоким давлением азота. Из-за низкого теплового эффекта и для повышения температуры процесса за счет реакции окисления в смесь были добавлены избыток алюминия и окислитель Mg(ClO4)2. Установлена зависимость микроструктуры AlON от вводимых добавок оксидов магния, лантана и иттрия. Представлены результаты по горячему прессованию AlON и механические свойства полученных компактов.
