Published: March 2023

Energi Matahari merupakan salah satu sumber energi terbarukan. Energi terbarukan merupakan salah satu dari energi alternatif sebagai pengganti bahan bakar untuk pembangkit listrik. Keunggulan panel surya yaitu ramah lingkungan karena tidak mempunyai limbah yang menyebabkan polusi. Selain itu perawatan panel surya relatif murah dan mudah dalam penerapannya. Tenaga listrik yang dihasilkan oleh sistem pembangkit listrik tenaga surya tergantung pada radiasi sinar matahari dan temperatur permukaan sel surya. Kedua parameter tersebut menyebabkan kurva karakteristik daya keluaran sel surya menjadi non-linier. Masalah utama penggunaan panel surya adalah efisiensi yang masih rendah. Memanfaatkan energi matahari didapatkan solusi yang mampu memaksimalkan tegangan yang disebut Maximum Power Point Tracker (MPPT). Maximum Power Point Tracker (MPPT) bertujuan untuk memaksimalkan daya Output yang diserap lebih optimal. Partial shading adalah Sebuah kondisi dimana panel surya menerima iridiasi yang berbeda. Partial shading menyebabkan penurunan efisiensi daya keluaran PV sehingga dapat menimbulkan kerusakan pada PV. Pencegahan kerusakan pada PV biasanya dilakukan pemasangan diode bypass namun adanya dioda bypass menyebabkan kurva karakterisistik daya-tegangan memiliki puncak lebih dari satu dan teralalu tinggi. Jika nilai tegangan tinggi menghasilkan nilai terlalu tinggi sehingga merusak komponen. Penelitian ini menyajikan usaha untuk meningkatkan efisiensi konversi energi oleh panel surya. Metode Perturb and Observe dengan simulasi MPPT menggunakan kontrol PID ditujukan untuk menghindari terjebak pada puncak daya yang lebih tinggi sehingga tidak merusak komponen dan lebih optimal dalam mendapatkan puncak daya-tegangan optimum. Efisiensi pengisian daya baterai menggunakan MPPT meningkat hingga 138% dibandingkan tidak menggunakan MPPT.

The paper considers principles of creating methods for calculation of railway stations and polygons. It shows that methods in existing instructions are theoretically based, in the essence, on logical soundness. The authors propose to consider a system approach in original statement as a scientific basis. A system is considered as a generally natural form of construction of organized matter which allows steadily functioning in environment with disorganization. An important property of the system is adaptability when structural elements enter a dynamic interaction. The authors state that in calculation models an element is assigned (consciously or not) a certain functional role that often doesn’t match a real role. Accordance of these roles is assumed as a main criterion of correctness of a calculation method. But the functional role is determined not only by properties of the element but also by a character of its interaction with other elements. That is why you can’t calculate a capacity of structural elements separately. The authors show on specific examples that it is possible to calculate the capacity only in a comprehensive model of the whole system. As a result, it is necessary to consider simulation modeling as a main method for calculation of systems of railway transport.

Published: March 2023

Special requirements are imposed to a modern specialist in the sphere of train management. These requirements are connected with learning of a big number of professional competencies and with a higher level of training in the sphere of transport safety because railway stations and nodes are strategic objects of a country. Distance technologies suppose not only learning with the use of «strict control», but also educational forms targeted mostly on conscious study - «involvement, not coercion». Consequently, a role of facultative lessons as an additional tool to widen the outlook of students of higher school increases. Acts of unlawful interference on transport are often dangerous for a big number of people and potentially lead to a significant material damage. In order to prevent such acts universities train profile specialists. However, future participants of the transportation process must be vigilant and must be aware of possible offence in the sphere of transport safety. Study of historical experience allows tracing the whole chain - from an origin of intent to attempts of concealment of criminal acts - and directly interacts with such disciplines as «Transport Law» and «Transport Safety», which allows forming knowledge on the basis of gained practical and theoretical information. The paper considers historical examples of unlawful interference into transport operation intended to students of higher educational establishments with the consideration for the use of distance technologies. As a result, the authors have substantiated the importance and practical applicability of learning in the form of additional education. They have also provided examples of materials for additional studying during extracurricular time.

Authors:   Institute of Transport Planning of the Russian Academy of Transport, Yakimov M. R.
Published: March 2023

The article discusses approaches to building an optimal route network for transport systems of various carrying capacities. The solution to this problem is the formation of the route network and initial volumes of traffic on it in the form of intervals of movement of rolling stock (all types of urban passenger transport, including water and rail transport). However, the most interesting task is the formation of a route network for public street passenger transport on routes. Based on the calculated intervals of movement, passenger and production schedules of regular transportation are formed, the required number of rolling stock is planned. It is shown that it is possible, without changing the passenger schedule, to optimize the volume of transport work by modifying the production schedule and reducing the volume of rolling stock production on routes. It is possible to reduce the initial maximum price of contracts for regular passenger transportation by means of a two-stage optimization of the volume of transport work, which makes it possible to form an effective model for organizing regular passenger transportation and minimize the average time for implementation of transport correspondence. As an example, the city of Berezniki (Perm Area) is taken, the solution of problems of forming the optimal route network for each selected type of transport is shown; the formation of the initial set of routes, formulation and solution of an optimization problem are presented: optimization of the existing set of routes according to a certain target criterion, taking into account the current restrictions in the field of transport offer.
The effect of a ballast resistor block on the efficiency of an electric circuit of the ac electric locomotive
Authors:   Irkutsk State Transport University (ISTU), Tomilov V. S.
Published: March 2023

In order to reduce electricity consumption when handling heavy freight trains, it is necessary to increase the performance characteristics of a regenerative braking mode of electric locomotives, the energy performance characteristics of which are currently unsatisfactory. In this article, the effect of the ballast resistor block on the efficiency indicator of the electric circuit of an alternating current electric locomotive is considered. The ballast resistor block is designed to ensure the static stability of the regenerative braking mode when organizing the inversion process of a thyristor rectifier-inverter converter with a constant margin angle δ = const. However, the use of ballast resistors in the anchor chain of traction electric engines negatively affects the energy performance characteristics of the electric locomotive in the regenerative braking mode. In order to eliminate this drawback, a method is proposed to ensure the stable operation of the regenerative braking mode without the block of ballast resistors of the alternating current electric locomotive with a rectifier-inverter converter based on IGBT transistors. The calculation of the efficiency performance characteristics of the electric circuit of an alternating current electric locomotive for the regenerative braking mode is presented both in the presence of the ballast resistor block in the power circuit and in the absence of it.

The article is devoted to mathematical modeling of cross-border railway transportation between Russia and Mongolia. As the object of the study, a section of the railway track from the station of Naushki (Russia) to the station of Sukhbaatar (Mongolia) was selected, on which there is package traffic and customs functions are performed with passenger and freight trains. The article presents a mathematical model of traffic on this section. It has the form of a queuing network with group service of applications. The arrival of train packages from different directions is described using several BMAP (Branch Markovian Arrival Process) streams. The use of this mathematical apparatus makes it possible to take into account various parameters of the operation of stations and tracks between them, as well as random factors which have a significant impact on the transportation process. Numerical methods, in particular, simulation modeling, were used to study the resulting mathematical model. By means of that, two computational experiments were carried out with the current and maximum planned train traffic. Based on the results obtained, a bottleneck in the system structure was identified and ways to increase its throughput were evaluated.

The development of information technologies and technical means of data registration creates conditions for filling simulation models of railway transport with actual data. It allows us to use simulation models to create digital counterparts of railway stations and junctions. The experience of using simulation models to perform the tasks of designing and operational planning of railway transport systems of various complexity is analyzed. An overview of modern computer programs for simulation of railway transport is presented, the advantages and disadvantages of the specialized software tools are illustrated. The authors propose an approach to build a digital twin of a railway junction based on the universal simulation tool AnyLogic. The problems and limitations of using simulation models in digital twins for operational management of railway stations and junctions are systematized. Software solutions are proposed, the implementation of which makes it possible to provide an adequate representation of the operational situation at the railway station in the digital twin. A three-level architecture of a digital twin of a railway junction has been developed, including a description of the track development scheme, the technology of the transportation process, as well as a method for synchronizing model and actual data. Examples of the interface of a digital twin of non-public railway tracks are presented. The implementation of the developed twin at the mining enterprise allowed to increase the efficiency of decisions taken to coordinate the work of production units and transport, reduce idle time and increase the productivity of the ore-processing mill as a result of supplying it with raw materials of the required range at a given time.

Published: March 2023

Increasing the interference immunity of automatic cab signaling receivers of the main locomotive safety devices using the path-locomotive inductive communication channel is a complex task which, in particular, can be solved by assessing the degree of influence of individual factors leading to equipment malfunctions en route. The present work is devoted to assessing the effect of asymmetry arising under the action of traction current flowing in the rail threads of adjacent tracks on multitrack sections of railways. Based on the Bio - Savard - Laplace law, a system of equations has been compiled to calculate the value of the asymmetry coefficient at the input of the cab receiver. The resulting system takes into account the asymmetry in the rail line of each of the tracks, displacement of the receiving coils relative to the axes and levels of the heads of the corresponding running rails. The analysis showed that in conditions of the receiving coils geometric position asymmetry, the asymmetry at the input of the cab receiver when moving along a multi-track electrified section can be five percent or more. In case of placing test sections of automatic cab signaling check-points on tracks adjacent to tracks intended for passing trains, the asymmetry coefficient at the input of the cab receiver reaches forty percent, which can lead to significant distortions of the results of the tests. The proposed equation system and the results obtained can be used to analyze the electromagnetic situation on multi-track sections of electrified railway lines.

This becomes a means of managing the quality of universities while supporting finance.
Finally, based on Japan's higher education financial support system, improvement measures were proposed for the direction, scope, size, and target of higher education financial support in Korea.
One Model, Multiple Stories? Using Agent-Based Models to Unveil Structural Similarities in a Complex World
Authors:   , Mayerhoffer Daniel
Published: March 2023

The doctoral thesis argues that such transfer of the structure of an Agent-Based-Model from one real world application to another is indeed possible by means of story adaptation to the new application case. If successful, the transfer benefits research in two ways: (I) It improves efficiency for modellers and readers alike; (II) it can reveal structural similarity between these cases and help to assess the extent of this structural similarity. Therefore, structure transfer is no mere auxiliary to Agent-Based Modelling but an independent scientific endeavour. However, such endeavour may also fail or mislead in the sense that an identified structural similarity between two modelled situations does not exist. Hence, model structure transfer requires a careful execution.

Ayrıca, sürdürülebilirlik performansının iyileştirilmesi için öncelikli alanların/göstergelerin belirlenmesi konusunda karar vericilere yardımcı olabilecek görsel bir harita tasarlanmıştır.Tartışma –Göstergeler düzeyinde toplu iş sözleşmesi kapsamında çalışan oranı değerleri; boyutlar düzeyinde ise sosyal boyut göstergeleri açısından işletmeler arasında daha fazla farklılık olduğu ortaya konulmuştur.2020 yılında sosyal boyutun toplam ağırlığındaki düşüşün, Covid-19 pandemisinin etkisi sonucunda işletmeler arasındaki sosyal gösterge farklılıklarının azalmasıyla ilişkili olduğu düşünülmektedir. Aynı yıl içinde sürdürülebilirlik skorlarındaki düşüşün ise pandemi döneminde işletmelerin üretim ve/veya tedarik süreçlerinde yaşadıkları sorunlardan ve çalışan eğitimlerindeki aksamalardan kaynaklanabileceği değerlendirilmektedir. Son olarak, sürdürülebilirlik performanslarını arttırmak isteyen imalat sektörü işletmelerine toplu işsözleşmesi kapsamında çalışan sayılarını arttırmaları önerilmektedir.

Authors: Çulhaoğlu Uludağ Candide
Published: March 2023

Purpose –The study aims to investigate how employees' Digital Literacy (DL) levels impact on Readiness for Organizational Change (RFOC). In addition, the study seeks to determine the mediating role of employee Resistance to Change (RTC). An analysis of the outcome of organizational change and digitization trends on employees' RFOC and RTC was conducted in this study. Employee attitudes toward digital technologies in the workplace, their RFOC, and their RTC are significant factors as a result of digitization trends in organizations. Design/methodology/approach –Although DL is discussed in detail in the literature, employee attitudes toward DL and digital technology, and their willingness to embrace organizational change, have not been explored much in light of RTC. First, the correlation between the research paradigm and the constructs that comprise the paradigm was tested in order to achieve the specified goal. Randomly, 317 white-collar employees of a Turkish retail company in the retail sector were selected for the accessible sample. The collected data was tested using IBM SPSS AMOS version 24 and the Structural Equation Model (SEM). All hypotheses were examined simultaneously with pathway analysis. For SEM, the assumptions were met and a maximum-likelihood estimation was performed. Findings–It has been determined that the level of DL of employees has a positive and significant impact on their RFOC with digitalization trends. In addition, RTC, which is included as a mediating variable in the relationship between the level of DL and RFOC, is assumed to have a mediating role in the research paradigm.Discussion –The findings show that the relation between DL skills and RFOChas been found to be fully mediated by attitudes of RTC.

Published: March 2023

Introduction. The field of Internet services is one of the most dynamically developing in our country. A key indicator of the effectiveness of vocational training institutions where young people study in IT specialties is the profile employment of graduates, to what extent their competencies contribute to getting a job or require additional training.Purpose setting. The article examines those niches of the labor market in the field of Internet services, where the competencies of graduates of the vocational school would be most in demand.Methodology and methods of the study. The list of promising niches of the labor market in the field of Internet services is formed on the basis of commercial education proposals published on the Internet and supplemented with generalized salary proposals from employers. The salary level, which acts as a means of assessing the demand for a specialty, is indicated in the following values: minimum, maximum, average and median.Results. Two groups of IT specialties have been identified that meet the above requirements: those with a low entry threshold, where the basic competencies obtained in vocational training institutions are sufficient for primary employment, and those requiring specific knowledge and skills that can be obtained with additional education.Conclusion. Despite the capacity and dynamism of the Internet services sector in our country, graduates of the vocational school are limited in terms of employment in profile IT specializations, since their basic knowledge and skills only to a small extent meet the requirements of the market. They can compete for jobs with a low entry threshold and, accordingly, low wages. But they can also improve their position in the labor market through additional education.

Published: March 2023

Introduction. The article examines the problem of the ambiguous influence of modern information technologies on education. Purpose setting. The authors analyze not only the positive effects of computerization. They also show the problems faced by the subjects of the educational process under the influence of digitalization.Methodology and methods of the study. As the article highlights, uncontrolled information flows prevent the formation of a holistic worldview among students. The dominance of information technologies in education also leads to the transformation of subject-object relations in the process of cognition. The authors investigate the factors that create the basis for structural changes in society. Digital technologies contribute to the activation of the communicative capabilities of representatives of various social groups, but they can also have negative consequences. In the modern world, there is a violation of traditional public relations, which creates conditions for potential conflicts in a certain society. According to the authors, in the information society, similar trends are observed in the relationship between representatives of different generations. Social inequality is also largely exacerbated by the active introduction of the latest information technologies, in particular, in schools. The article proves how the latest information technologies provoke social tension due to the impossibility of providing equal access to all information resources to citizens for all.Results. The role of the teacher is changing significantly, because he often acts as a coordinator. The use of gadgets in the educational process provides an opportunity to get an education at a distance. However, the widespread use of distance technologies leads to a drop in the quality of educational services. This is due to the need to develop new techniques. In addition, the constant updating of information technologies does not allow the teacher to develop a sustainable methodology for teaching his subject.Conclusion. The authors prove that the active use of digital technologies in the information society implies a harmonious combination of traditional and modern information technologies. This fully applies to the modern domestic education system.
