      <title>Improving the Energy Efficiency of Railway Electrical Traction by Creating Smart Grid System</title>
      <link>https://trid.trb.org/View/1975316</link>
      <description><![CDATA[The article presents technical solutions to improve the energy efficiency in the system of traction rail power supply. Railway transport is a powerful consumer of electricity. A rather high part of the cost of railway transportation is determined by the cost of electricity consumed. In connection with the constant increase in the cost of electricity, an urgent task is to increase the energy-efficiency of electric transport systems, which will ensure a reduction in the cost of rail transportation. To improve the energy efficiency of electric traction, the concept of an intelligent traction power supply system is proposed, which provides monitoring and control of the transmission of electricity to the traction network. This system ensures the rational use of the recovery mode at the traction substations and in the electric rolling stock, work with powerful electrical energy storage devices, as well as connecting alternative energy sources to the traction power supply network. The Matlab/Simulink is used for developing a simulation model of the proposed intelligent traction power supply system. The research audience is engineers and scientists who work in the field of energy and railway power supply systems.]]></description>

      <title>Evaluation of the Support-Coupling Patency of Self-propelled Transport</title>
      <link>https://trid.trb.org/View/1975276</link>
      <description><![CDATA[It is established that basically all the known indicators of the evaluation of the patency of machines are single, which allow them to be compared only on one specific indicator. At the same time, the support and coupling indicators for assessing the patency of machines are also evaluated separately. Moreover, it is known that the support and coupling indicators of the permeability of machines have an impact on each other. In this regard, the relationship between the support and coupling indicators of their permeability is not taken into account when assessing the patency of machines. At the same time, the smaller the bearing capacity of the soil base, the more intense it is manifested. Therefore, the calculation equations for the evaluation of interconnected coupling and support indicators of self-propelled machines are proposed. The results of calculations on the proposed equations confirm their adequacy to the practical data obtained during the operation of specific self-propelled machines.]]></description>

      <title>The Spread of Supply Chain’s Consumers’ Emotions as Function of Their Social Network Structure</title>
      <link>https://trid.trb.org/View/1975274</link>
      <description><![CDATA[Modeling and simulation of complex sociotechnical systems such as supply chains and consumer markets include not only strictly the rational but the social components as well. Consumers are impacted by various parameters such as others’ opinions, rumors, overall mood of the community etc. Computer simulations are often used to observe how such phenomena form and change in time. The systems theory principles state that the system’s dynamics cannot be researched independently from the system’s structure, i.e., it is necessary to investigate the media over which the system operates. This leads to the inference that next to the observable behavior of the model, the structural composition must be considered. The paper investigates how different types of network structures impact the dynamics of contagion processes, in particular, the emotional state dynamics. The paper applies graph theory and network metrics to show that the structure parameters have an impact on the dynamics of the contagion.]]></description>

      <title>Visual Analytics in Mobility, Transportation and Logistics</title>
      <link>https://trid.trb.org/View/1975272</link>
      <description><![CDATA[Mobility, transportation and logistics are more and more influenced by a variety of indicators such as new technological developments, ecological and economic changes, political decisions and in particular humans’ mobility behavior. These indicators will lead to massive changes in our daily lives with regards to mobility, transportation and logistics. New technologies will lead to a different mobility behavior with new constraints. These changes in mobility behavior and logistics require analytical systems to forecast the required information and probably appearing changes. These systems have to consider different perspectives and employ multiple indicators. Visual Analytics provides both, the analytical approaches by including machine learning approaches and interactive visualizations to enable such analytical tasks. In this paper the main indicators for Visual Analytics in the domain of mobility transportation and logistics are discussed and followed by exemplary case studies to illustrate the advantages of such systems. The examples are aimed to demonstrate the benefits of Visual Analytics in mobility.]]></description>

      <title>Process Support and Visual Adaptation to Assist Visual Trend Analytics in Managing Transportation Innovations</title>
      <link>https://trid.trb.org/View/1975262</link>
      <description><![CDATA[In the domain of mobility and logistics, a variety of new technologies and business ideas are arising. Beside technologies that aim on ecologically and economic transportation, such as electric engines, there are also fundamental different approaches like central packaging stations or deliveries via drones. Yet, there is a growing need for analytical systems that enable identifying new technologies, innovations, business models etc. and give also the opportunity to rate those in perspective of business relevance. Commonly adaptive systems investigate only the users’ behavior, while a process-related supports could assist to solve an analytical task more efficient and effective. In this article an approach that enables non-experts to perform visual trend analysis through an advanced process support based on process mining is described. This allow us to calculate a process model based on events, which is the baseline for process support feature calculation. These features and the process model enable to assist non-expert users in complex analytical tasks.]]></description>

      <title>Fastening Device of the Railway Rolling Stock</title>
      <link>https://trid.trb.org/View/1975260</link>
      <description><![CDATA[In the paper the fastening device of the railway rolling stock is described. The main idea of the construction was its simplicity and safety. The device consists of brake pads, which are mounted on the running rails with typical rail linings. Brake pads are put and removed from the heads of the running rails, using a track switch. Additional elements, namely laser and Parktronic, are built into the brake pads. Elements send the signal through the radio transmitter into the driver’s cabin, about the distance left to the complete rolling of the wheel pair on the brake shoe. Due to this device, the accuracy of the rolling stock fastening is increased. When the train departs, the driver receives a signal through the radio transmitter about whether the shoes remained under the wheel pairs.]]></description>

      <title>Using the New Car Braking Systems in Marshalling Yards</title>
      <link>https://trid.trb.org/View/1975257</link>
      <description><![CDATA[The purpose of the work is substantiating conditions for use of the target gravity braking technology for railway cars. To implement this technology, a marshalling system with a specific plan and profile design is proposed. Unlike conventional marshalling humps, the proposed system does not have any braking positions on the descending slope. The speed of cars rolling down from the hump is reduced with the help of the brake position in the classification bowl and elevations before it. Sufficient intervals between the groups of cars on switches are ensured only with the longitudinal profile. The main advantages of the marshalling system with target gravity braking technology include the significantly simplified rolling speed regulation without need for automated braking on the descending slope, and reduced effect of human factor and random parameters. Conditions of use of the target gravity braking technology are justified on the basis on the analysis of the calculation data of the rolling parameters of estimated cars with different values of uncoupling speed, wind speed and direction, permissible trailing-point movement speed and exceeding the permissible speed of entering the parking retarder position.]]></description>
