Published: May 2020

Using the space infrastructure as an example, a multi-criteria selection tool for navigation receivers was developed on the basis of scientifically substantiated fuzzy preference method. This task is an integral part of the bigger fundamental scientific problem aimed at improving the use of information provided by spacecraft to solve the most important problems of socio-economic development of Russia. Today, a large number of suppliers of these products are presented in the market. Given the interdisciplinarity, multivariance and complexity of the study of the problem under consideration, it is decomposed to a rational choice of navigation receivers of signals from global navigation satellite systems that allow working with GPS, GLONASS, as well as with sophisticated GALILEO and BeiDou systems. This is a multi-criteria challenge, the solution of which must be found in a complex information environment. Therefore, the selection of a specific supplier and model is a non-trivial task. The methodology of the study is based on the theory that the issues of state security, sanctions risks, consumer qualities and economic criteria are a part of an equation.

Authors: Vakhnin A , Sopov E , Panfilov I
Published: May 2020

Large-scale global optimization (LSGO) problems are emergent in many domains of applied sciences. LSGO is a hard challenge for the majority of state-of-the-art optimization methods. Evolution algorithms (EAs) combined with Cooperative Coevolution (CC) are able to perform well when solving many real-world LSGO problems. The grouping of variables at the problem decomposition stage has a significant impact on the performance of the CC approach. This study proposes an improvement of the previously developed random adaptive grouping (RAG) approach for CC. The new method is titled as RAG2, and the whole optimization algorithm, based on RAG2, is called CC-SHADE-RAG2. The influence of the choice of the population size and the number of subcomponents on the algorithm performance have been investigated using the IEEE LSGO CEC’2013 benchmark. The set of test problems in the benchmark contains fifteen functions with dimensionality equal to one thousand. We have also compared the performance of the novel algorithm with some EAs, which are applied for solving LSGO problems.

Visual methods of high-level system design for digital hardware components
Authors: Khalzev S E , Vlasov A I , Shakhnov V A
Published: May 2020

The article presents an analysis of using xtUML for high-level design of very large-scale integrated circuits. A design flow of digital VLSI circuits was investigated. The focus was made on the formalisation of the digital circuit models at the initial stages of system design. We studied specific features of developing a digital circuits’ system model that includes the behavioural description and the environment of the system being developed. This makes it possible to show the interaction between the very large-scale integrated circuits and other hardware components or measurement objects. However, further transition from the system level to the lower level in the hierarchical decomposition reveals the problem of “semantic gap”, meaning the complexity of the automated interpretation and formalisation of the conditional “rectangles” of the visual model to the form which could be interpreted by the tools used at the low-level design stages. The use of visual methods of system design is effective in the development of modern and highly sophisticated systems on a chip. We analysed xtUML diagrams at the system level of the digital very large-scale integrated circuit projects and formulated the procedure of using xtUML for developing digital VLSI circuits’ system models.
Comparative analysis of the fatigue characteristics of repaired compounds of the “T” and “K” types of fixed offshore platforms
Authors: Starokon I V
Published: May 2020

The study of the fatigue characteristics of repaired welded joints is an important task to determine their remaining lifetime. At present, there is no methodology that allows calculating the resource of reconditioned welded joints; therefore, industrial safety experts use the diagrams and fatigue equations given in the normative documentation for new joints when extending the resource. It is also not established whether there is a difference in fatigue characteristics depending on the type of pipe joint “T” or “K”. In this regard, the authors conducted research during which a new welded joint was brought to primary failure, and then repaired and brought to repeated failure. Based on these experiments, graphs were constructed that describe the dependence of the number of cycles on the values of the amplitudes of the alternating stresses and a mathematical equation was obtained that describes the fatigue parameters for both “T” and “K” types of welded joints.

Modernization of a tractor motor for diesel combustible and methanol
Authors: Anfilatov A A
Published: May 2020

When carrying out research to improve the environmental performance of motors, attention should be paid to reducing the nitrogen oxide content of the effluent gases, since they are the most toxic components among the entire range of polluting chemical compounds contained in exhaust gases, since they are formed in the burning process as a result of chemical reactions atmospheric oxygen and nitrogen. The most effective way of using methanol in internal burning engines is now to feed it directly to the diesel cylinder using a dual combustible supply system, which allows replacing up to 80% of the diesel combustible. The ignition of methanol in this case is due to the supply of a seed portion of diesel combustible. This method, with some changes and additions to the design of the motor, can be implemented on engines already in operation. In this paper, the effect of methanol application on the volumetric content and mass concentration of nitrogen oxides in exhaust gases calculated on the basis of the results of experimental studies of a motor of 2H 10.5 / 12.0 air cooling with a hemispherical burning chamber in a piston using a dual combustible delivery system and injection of diesel combustible (ignition) through a multi-jet nozzle, depending on the change in load.

Authors: Bolotov A N , Novikov V V , Novikova O O
Published: May 2020

The paper proposes a new metrological assurance to study functional properties of promising magnetic lubricants: liquids and oils. They contain chemically active components to improve their triboengineering characteristics and therefore cause corrosion of solid surfaces interacting with them. The proposed method for assessing corrosion activity of magnetic lubricants takes into account all conditions of chemical corrosion during friction. A metal filament, in which cyclic electric current and a magnetic field create alternating tension stresses and a temperature similar to the real one in the frictional contact area when using a magnetic fluid tribonode, undergoes corrosion in the magnetic medium. The theoretical justification of the method has two different cases of filament fixation. The nature of the filament movement and its tension under the influence of alternating Ampere’s force and alternating sign current pulses is analyzed. There is a diagram of a device for assessing corrosion activity of magnetic lubricant nanodispersed materials. There is a performance evaluation of the proposed method and an experimental research on the effect of corrosive magnetic and non-magnetic lubricating media on a solid copper surface. It is established that the excess of free surfactant in PES-5 organosilicone liquid and its magnetic oil is negative.

Authors: Pushkarev O , Bagaiskov Yu
Published: May 2020

Micromechanical properties of abrasive material grains of fused alumina and silicone carbide are investigated applying the microindentation method. Such parameters as microhardness, microbrittleness, and microstrength were evaluated depending on the penetration depth of the Vickers diamond pyramid to the 0.5 — 5.0 µm thick surface under analysis. The microhardness parameter is the stress required for formation of a brittle failure area within the pyramid imprint. The microbrittleness criterion defines the ratio of the brittle failure area within the imprint and the imprint area. The power-law dependence of the parameters on the pyramid penetration depth is established: the lower the depth, the higher are microhardness and microstrength, yet the lower is microbrittleness. The obtained results enable creation of a standard basis, forecasting of the performance level of abrasive tools, refractory and wear-resistant items, filters, and special ceramics.

For this, one should have the mathematical models in the transfer functions form. The basic motor model is non-linear therefore, it should be linearized using the Taylor series. A block diagram is created according to the obtained system of linearized equations. Then the sequential transformation of this block diagram is performed with a gradual decrease in the number of contours. The block diagrams can be used to obtain the motor transfer functions with the arbitrary combination of input quantities (the amplitude, voltages, the frequencies of two voltages) and output quantities (the speed and the rotation angle).

The postmodern era now, of course, influences by the development of this architecture. The benefits of local wisdom are explored by examining the existence of abstract and concrete spaces in Karo traditional architecture. For this reason, the article aims to look at the development of the existence of Karo architecture in its abstract and concrete spaces. The objects of research are Karo traditional buildings and shop houses located in Karo Regency and its surroundings. The method used is the descriptive qualitative approach to describe the facts in the field and examine them with the theory used. The result is that existing spaces are the results of culture from generation to generation that produces meaning according to their needs or Karo’s contemporary culture can adapt shop house.

A historic building is a building that is closely related to the historical aspects of an area or city. Historical buildings can be used by future generations to remember their predecessors. In the context of the city area, the existence of historic buildings can trigger the development of the surrounding economy. This economic development happened in the case studies studied, namely the area around Menara Kudus, Indonesia. The area around Menara Kudus is an area crowded with tourists and pilgrims because of Menara Kudus, the Tomb of Sunan Kudus and the Al-Aqsa Mosque. Crowds of tourists and pilgrims who visit Menara Kudus area also influence the arrangement of the surrounding area. This study uses a qualitative descriptive method that analyzes interpretatively the data obtained in the field. The analysis process carried out is the identification and description of three things. First, historical buildings in Menara Kudus area. Second, economic development around the area of Menara Kudus. Third, structuring the area of Menara Kudus. Of the three identifications and descriptions, interpretations were then made to get the influence of the existence of historical buildings on economic development and regional arrangement. The results shows the more crowded tourists and pilgrims who come to Menara Kudus, the more economic growth achieved in the region. Evidenced by the arrangement of the area which was finally adjusted to the economic conditions.

Generally, Shop houses in urban area appear dominantly, because it is very rational in term of economic and financial such as “cost and benefit analysis”, is that absolutely right? These believed is a kind of simplification of the main issues in term of modernist and materialistic philosophy, since the local culture and the local architecture has been totally denied. A number of method has been applied to found and to identified local urban vernacular architecture. One among them is research on shop houses which socially adaptable with individual life of modern society but also accommodate the social aspect of local traditional life. This research basically is using qualitative method and focused on genius loci in shop houses in urban secondary cities in Sumatera Utara, where local culture and local architecture is still dominant. In this research Brastagi city in Karo regency will be posed as a study case. There is the main hypothesis on the spread of shop houses into the urban secondary urban cities because the shop houses have the great potential to make an adaptation with local culture and local architecture. In fact, the problems in this study is very wide, consequently, although research focused on architecture, other discipline has to be discussed namely philosophy and anthropology. With these method, the research revealing why the local peoples can adapt themselves socially and culturally with the shop houses. A number of research has focused on genius loci by using qualitative methods in order to find genius loci in architecture of Urban Shop Houses in Karo.

Jakarta is the capital city of Indonesia with a very dense population, approximately four million of the thirteen million in Jakarta area traveling to and from the city every working day. MRT can be an alternative transportation solution for those who are also environmentally friendly. The life and economic activity of a city depend on how easy the city residents travel or their mobility and how often they can do it to various destinations in the city. The city of Jakarta, which has a traffic density, will have an obvious impact when the MRT has been running effectively. The change in attitude and mentality of people who are using MRT will be obvious, especially the changes in different individual’s experiences with specific patterns combined with particular objects in a particular space and time. Which in this case, the application of behavior setting can be a theory that can be explored as a built environment created by people, in connection with the above understanding, the behavior setting in architecture explains the relationship between human behavior and the environment, especially the architectural space. Therefore, the existence of the MRT, which represents a breakthrough in public transportation, will significantly influence the behavior set with its environment. Thus, through this theory, it will be seen the suitability between the behavior setting that is formed with the function of space at the Blok M, Jakarta MRT Station.

There have been many experiments regarding reusing plastic bottles, especially polyethylene (PET) as building materials. Some of them are experimenting with their compressive strength as exterior wall bricks (Mansour, et al., 2015); their energy consumption as roof insulations (Racolta, et al., 2016); their compressive and flexural strength as interior walls (Santana, 2016); and their compressive strength as walls and slabs (Oyinlola, et al., 2018). This paper discusses the compressive strength and the flexural strength of PET bottles as structural floor panels. This study explored the positions, binders, patterns, fillers, sizes, and supports of the PET bottles panel to reach the optimum combination of compressive and flexural strength. The experimental result shows that PET bottles panel with an upright position, sealant binder, and sand filler has better compressive strength and flexural strength. It also shows that the panels with more bottles face downwards have better compressive strength, while the ones with more bottles face upwards have better flexural strength. On the other hand, panel with smaller size and higher amount of support shows better flexural strength.

The substructure is an essential part of vernacular buildings, especially in an earthquake region. The substructure durability is proven since the vernacular house sustains while modern house destructed after the experienced earthquake. The use of substructure in the earthquake region is dominated by the stepped on stone pillars while the non-earthquake territory is dominated by pierced to the ground pillars. Researches hypothesized vernacular buildings in the ring of fire area will stable uses a stepped on the stone substructure and the joint wood system which interlocks the blocks. The purposes of this research are to determine whether the substructure can withstand the existing load, including earthquake and the wood material performance related to its durability in facing the weather and destructive biological factor. The test was done using a monotonic testing method to analyze the load exposed to the substructure. The moisture testing was also conducted in wood materials using Wood Moisture Detector MD818, and wood chemical structure was tested using FTIR. The result showed that the Aceh vernacular house was able to withstand earthquake load, including durable construction and material system. Aceh Besar vernacular house durability on earthquake was influenced by structure properties with a ductile value of 2.27.
