One of the main conditions for using the efficiency of the use of freight traffic is the substantiation of the technical standards for loading into a carriage, which makes it possible to increase the efficiency of using a freight car. The analysis showed that the carrying capacity of the car is not fully utilized, and in order to increase the carrying capacity of the car, options for the transportation of bulk freight transport have been proposed. The article considered options for the transportation of bulk cargo in bags and soft containers (big bags), they were also compared, for the further release of a specialized wagon fleet for the transportation of export types of cargo. The aim of the study is to substantiate the choice of the type of wagons for the transportation of bulk cargo by rail. The research methods are based on the existing methods of searching for the rational transportation of goods by rail. A methodology for calculating options for placing cargo in a car is presented. A technical and economic calculation of the effectiveness of the options under consideration for transportation by rail has been made, which in turn will determine a rational option for the transportation of bulk cargo. Recommendations are given for the transportation of bulk cargo by rail, which, in turn, will make it possible to correctly and rationally choose the type of carriage and make the most of the carrying capacity of the carriage, depending on the conditions of transportation.

Abstract It is a challenge for the dynamic inspection of railway route for freight car transporting cargo that out-of-gauge. One possible way is using the inspection frame installed in the inspection train to simulate the whole procedure for cargo transportation, which costs a lot of manpower and material resources as well as time. To overcome the above problem, this paper proposes an augmented reality (AR) based dynamic inspection method for visualized railway routing of freight car with out-of-gauge. First, the envelope model of the dynamic moving train with out-of-gauge cargo is generated by using the orbital spectrum of the railway, and the envelope model is matched with a piece of homemade calibration equipment located on the position of the railway that needs to be inspected. Then, the structure from motion (SFM) algorithm is used to reconstruct the environment where the virtual envelope model occludes the buildings or equipment along the railway. Finally, the distance function is adopted to calculate the distance between the obstacle and the envelope of the freight car with out-of-gauge, determining whether the freight car can pass a certain line. The experimental results show that the proposed method performs well for the route selection of out-of-gauge cargo transportation with low cost, high precision, and high efficiency. Moreover, the digital data of the environments along the railway and the envelope of the freight car can be reused, which will increase the digitalization and intelligence for route selection of out-of-gauge cargo transportation.

For the determination of a potential benefit from creation of a distribution centre the paper proposes a method and presents results of calculation of a decrease of total number of rides and total run of automobiles at various variants of goods consolidation. The authors have established a positive influence of the centre on intracity transportation. At the same time, high efficiency of the considered technology can be reached by involvement of a bigger number of consignees and by consolidation of a relatively small number of goods batches in one automobile at efficient routing and correct selection of location of a distribution centre.

Introduction. Color terms constitute a most archaic lexical stratum of any language. Being characterized by vivid ethnocultural specifics, those serve as important elements to the linguistic view of the world. Goals. The paper seeks to analyze semantic features of the Kalmyk color term улан ‘red’ and its German translation equivalents. Materials and Methods. The work explores Kalmyk folktales recorded by the Finnish scholar G. J. Ramstedt during his 1903 scientific expedition to the Kalmyk Steppe. The analysis of the color term comprises both general research methods and specifically linguoculturological ones, such as linguoculturological and conceptual insights into folklore texts. Results. Impacts of color in world perception of the Kalmyks — just as for any other nation — are diverse enough. The folktale texts recorded by G. J. Ramstedt contain a total of five shades of the color, the lexeme улан ‘red’ being largely characterized by positive semantics. German translation variants are not always complete semantic equivalents of the color term which results from that color denoting lexemes — and those of red in particular — are integral to a certain ethnic worldview, this leading to some ambivalence of the color under study. Conclusions. The lexeme улан ‘red’ in its first nominative meaning denotes a color of an object, e.g., red proper, scarlet, ruddy, etc. In the Kalmyk language, it also serves to denote the prototypic color of blood and is often used to describe animal coat colors. The Finnish scholar employed different German translation means. In most cases, the selection of translation equivalents depends on the translator’s associative/visual thinking and perception of the world, as well as on lexical, semantic and morphological patterns of Kalmyk and German. Folklore texts are structured specifically, and a translator needs utmost attention and linguistic intuition to avoid any inaccuracies when communicating a color paradigm from the original text. The challenge be tackled by a translator of color terms in a folklore text is that he/she is supposed to bear both the linguocultures examined.

Prenatal diagnosis (PD), as a relatively new area of ​​medical genetics, is experiencing a period of rapid growth. Methodological problems of PD associated with the selection of women at high risk of congenital and hereditary pathology, complex examination of the fetus using non-invasive (ultrasound) and invasive (cytogenetic, molecular, biochemical) research methods have already been resolved. Further increase in the effectiveness of PD, its scientific and practical significance depends entirely on the level of organization of this service in the field and its funding. An important role in the development of modern PD in Russia was played by the PD laboratory of the N.I. BEFORE. Otta RAMS.

Air transport is developing at a rapid pace globally and is of particular importance for the mobility of people and goods. Through its flexibility, it responds to the ever-changing situation in commodity markets and provides the necessary conditions for transport services’ supply and demand in shortening the delivery times. The main subject of analysis in the presented article is the development of air freight transport over the last 12 years. The main results of the analysis of the volumes and changes of freight traffic to and from Bulgarian airports, as well as carried by the main carriers, give the grounds for SWOT analysis and is used to outline the main prospects for the future of air freight transport. The main objective of the survey presented is to outline trends for the development of air freight transport in the country and in particular to clarify the various factors influencing the demand for freight transport by identifying a system of indicators measuring the freight volumes and the loading work carried out, which can be analyzed regularly, and which allows the forecasting of changes in freight volumes during certain periods of time.

Abstract Passenger rolling stock often operates with a softer suspension than used in freight cars, in order to obtain good ride quality. In order to maximize seating, interior width forces exterior width to approach Plate C freight car dimensions. Close clearance to platforms is an important safety consideration for passenger entrance and egress. The associated rolling stock and platform designs need to be considered as clearance issues, especially in mixed passenger and freight traffic operations. Some passenger railroads that operate self-propelled cars use a third rail for power collection, which presents a clearance constraint on curves, particularly for the undercar equipment that is common on these cars. Maximum height at center of cars and locomotives is constrained by catenary clearance in some operations. Clearance considerations for passenger rolling stock on new and/or existing properties are covered using a general approach. Examples are presented which illustrate some of the factors that need to be considered in clearance investigations.

BACKGROUND: Selecting the most suitable questionnaire(s) in comfort research for product design is always a challenge, even for experienced researchers. OBJECTIVE: The objective of this research is to create a list of Preferred Comfort Questionnaires (PCQ) for product design to help researchers in the selection of questionnaires for comfort research. METHODS: Fifteen questionnaires that are often used in comfort research for product design were selected as candidate questionnaires. During the Second International Comfort Congress (ICC 2019), 55 researchers and practitioners working in the field of comfort joined together in a workshop to rate these questionnaires individually as well as rank them in groups based on their experience. The criteria of rating and ranking included easiness to answer, easiness for data interpretation, time needed to complete, the need for prior training, as well as mapping the applicable design phases and field of application. RESULTS: The elicited responses related to each questionnaire were analyzed. For comfort research in five proposed application fields and four design phases, the preferred questionnaires were highlighted and categorized into four categories: preferred questionnaire, suitable for less prior training, suitable for fast completion and generally applicable, which led to a list of PCQ for product design. CONCLUSION: We expect that the PCQ list can be used as a useful instrument to help researchers in selecting questionnaires for comfort research in product design.
