Authors: Arous N N , Goryachev M G 
Published: July 2021

Abstract
Comparative design of structures allows at an early stage of project development to assess their behavior and predict service life. Approximate numerical methods, for example, the finite element method, are widely introduced to simulate the operation of pavements on road structures. The variety of modern asphalt concrete poses the problem of finding the most effective design solutions based on the results of comparing the performance indicators of road pavements. The article presents the results of modeling by the finite element method of the work of road pavements, consisting of a two-layer asphalt-concrete package, on a reinforced concrete slab of bridge. Various options for combinations of asphalt concrete are considered. The well-known American method of the Asphalt Institute was used as a methodological basis. For the criterion of the limiting state, the indicator of accumulated fatigue cracks in the amount of 10% of the wheelpath area is taken. Preliminary recommendations are given on the field of application of the considered road pavements on reinforced concrete bridges in the conditions of the Syrian Arab Republic.

Published: July 2021

Abstract
This article describes the technological diagram and equipment required for establishing a Ready-Mixed Concrete Recycling System, which allows to divide concrete into separate components, such as cement milk, crushed stone and sand. The waste from demolished concrete structures can be reused to reduce the environmental burden during their life cycle and ensure economic use of the construction resources. The recycled aggregate concrete is a sustainable concrete waste which in the long term can replace the demand for natural aggregate, a process which would, in turn, lead to its preservation. Most concrete industries have been observed to be reluctant in the production of recycled aggregate concrete and utilization in its maximum potential. Industries are yet to embrace it not only due to its uncertain material performance but also due to its unexplored manufacturing plant operations which are yet to be established. The system is using wireless communication technologies and data exchange between sensors and data acquisition devices. The raw materials obtained by the showcased recycling process could be reused in subsequent production cycles of ready-mixed concrete preparation. The following process could help reduce the growing amount of industrial waste generated with constant infrastructure improvements, which could be beneficial both from an environmental and economical standpoint.

Authors: Shelmakov S V , Grigoreva T U 
Published: July 2021

Abstract
The article describes the methodology for assessing the impact of road traffic management (RTM) measures on the environment and public health. As an approbation of the methodology, such measures as ban on the movement of heavy trucks, ban on the movement of cars worse than the third ecological class and organizing the movement of non-motorized transport (NMT) are considered. Assessment of these measures impact on the environment was to provide an assessment of the pollutant emissions by the transport flow, the maximum and annual average ground-level concentrations of pollutants at the adjoining territory, the traffic flow noise characteristics (TFNC) and the equivalent sound levels at the adjoining territory. These estimates formed the basis for calculating public health risk indicators. Studies have shown that the greatest efficiency can be provided by measures to organize the movement of NMT and ban on the low environmental classes’ vehicles movement. It is also shown, that in addition to the traffic flows characteristics, specific features of the territory under consideration also have a significant impact on the results.

Published: July 2021

Abstract
The article substantiates optimal and most promising composition of a powdery thermoplastic composite polymer material used to restore worn-out rolling bearing units seats with combination of electrostatic and vibro-vortex coating methods. A laboratory installation for applying and forming coatings by a chamber electrostatic method is presented, with the help of which coatings were applied to steel 45 and AL-4 aluminum samples, after which they were melted in an oven at a temperature of 220 °C for 10 minutes. Based on the studies carried out, the optimal composition of the powdery polymer composition was determined: epoxy oligomer-32 … 40 %, powdered glass fiber-9.8 … 11.6 %, the rest-polyamide 12. At the same time, the coatings obtained from this composition on aluminum alloys substrates have insufficient adhesive strength. Therefore, the search for ways to increase it is relevant, and the solution of this issue will create a reliable technology for restoring rolling bearings seats.

Authors: Othman D M , Roshchin A I 
Published: July 2021

Abstract
The problem of planning public transport in most Syrian cities is an essential problem since until now almost no one has addressed it. The reasons for this are the lack of adequate information about volumes of passenger traffic and the work of urban passenger transport, which affects on the quality of decisions made by the management of transport organizations, which, as a rule, choose either unsuitable systems for organizing urban passenger transport (UPT), or allow private operators to make their own decisions. Depending on the results of practical researches of passenger transportation in the province of Latakia, as well as after studying the social standards of different countries of the world, including the Russian Federation, authors have defined some parameters which that characterize the passenger experience before, during and after each trip. These materials have allowed to formulate recommendations in the field of public transport passenger service in the form of minimum social standards. These standards should become the basis for Improving public transport services for passengers not only in Latakia province, but also in Syria as a whole.

Published: July 2021

Abstract
The article presents the results of an assessment of the impact on the environment and public health of measures to prohibit entry into a certain territory of the city of cars belonging to low environmental classes (“ecological zone” or “ecozone”). When justifying the choice of the city on the example of which the research was conducted (Novosibirsk), both environmental and socio-economic aspects were taken into account. The assessment of the environmental impact of the ecozone organization consisted in modeling traffic flows on the road network before and after the organization of the ecozone, estimating the emissions of pollutants from the totality of traffic flows, calculating the maximum and average annual surface concentrations of the considered pollutants on the territory of the ecozone. Based on the calculated average annual concentrations of pollutants, characteristics of the population density living in the ecozone, and scenarios of its interaction with pollutants, public health risk assessments were carried out before and after the organization of the ecozone. Studies have shown that the change in gross emissions of major pollutants during the organization of the ecozone in Novosibirsk will be 40…60%. Ground-level concentrations of these pollutants will decrease by about the same amount. Carcinogenic and non-carcinogenic risks to the population will be reduced by about half.

Abstract
The article considers some aspects of the modeling of the working process and structure-borne noise of a diesel engine in a transient mode. The main factors that cause differences in the diesel working process from similar stationary modes are described. A method for calculating the structure-borne noise from the diesel working process at the transient mode is presented. A study of the noise of a 6-cylinder (S=10.7 cm, D= 12,4 cm) diesel engine during acceleration was performed. The results of calculations showed that the noise of the 6-cylinder diesel engine is 2… 3 dB higher in the entire range of engine speeds compared to similar speeds in steady-state for diesel full-load characteristics.

Published: July 2021

Abstract
Further tightening of environmental rules and standards regulating the content of toxic substances in diesel exhaust gases, accompanied by an increase in the requirements for their fuel efficiency, creates prerequisites for the creation of Russian common rail fuel systems (CR). The performance of this task is possible with the use of new engineering solutions in combination with computational and experimental research methods implemented on the basis of the integrated computational and experimental complex IKTS-MADI. The complex consists of computing and research components. The computing component of the IKTS-MADI allows calculating the working processes of the entire high-pressure line when the high-pressure fuel pump (HPFP), rail and electro-hydraulic common rail injectors (CRI) work together, taking into account the influence of wave phenomena on the distribution of injection parameters across diesel cylinders. Obtaining new data to expand the library of existing technical solutions and testing of fuel equipment samples designed using mathematical modeling are carried out on the research component of IKTS-MADI. The CR and its components are tested together with the control system (control unit, sensors and wiring harnesses). The injection characteristics required for calculating the diesel operating process are recorded.
Evaluation of SVM modulation methods for indirect two-level three-phase frequency converter and direct frequency converter
Authors: Tung Le Van , An Ngo Van , Hieu Le Dinh , Long Thanh Pham 
Published: July 2021

Abstract
In current practice, indirectly structured frequency converters are popular because of the simple switch and control circuit diagram, and pulse width modulation (PWM) can be used to control the semiconductor switches. The PWM method has the advantage of a simple control circuit but has large switching losses and generates a common-mode voltage that causes motor damage. The development of the space vector modulation (SVM) method takes advantage of the PWM method, reducing the switching loss of the switches and reducing the harmonic at the output of the inverter. With direct converters, there are many types depending on the circuit structure and semiconductor key structure, including matrix frequency converters which are widely studied. The classical modulation method according to the duty-cycle matrix approach for matrix converter has disadvantages such as complex computational algorithms, which require many trigonometric calculations. Based on the PWM and SVM modulation algorithms for indirect converters, a space vector modulation method for matrix converters will be developed. Compared with the indirect converter, the SVM modulation method for the matrix converter will be based on two separate modulation principles: control the input current vector and control the output voltage vector. The relationship between current and voltage at the converter input is closely related to the voltage and current at the output. The relationship between current and voltage at the converter input is closely related to the voltage and current at the output. Make sure at the input of the converter, the power factor cosφ = 1 and can be adjusted, it has the quality of sine input and outputs current and the exchange power in two directions.
