The purpose of the research is to estimate the opportunities to promote the transport systems development by the means of introduction of weight-and-dimensional control and improvement of its methods. The existing methods of weight-and-dimensional control are considered. Advantages and disadvantages of the systems in comparison are revealed. According to the research, such results as the reduction of cases of excesses of admissible mass of freight, collecting additional income for the regional budget, the decrease in the destroying impact on highways, the decrease in the expenses on their repair as well as providing sources for financing of such repair, the decrease in ecological harm from driving of overloaded vehicles, the increase in traffic safety, the reduction of quantity of accidents and life losses caused by driving of the overloaded vehicles are possible. Nevertheless, the analyses of the domestic practice prove that some problems of the organization of weight-and-dimensional control exist. The author offers some measures for the solution of these problems. The results of the research can be used both by the specialists of Ministry of Transport, when drawing up the programmes of the transport system development and during approval of rules and standards of freights transportation, and by the transporters, when planning their activity.

The main characteristics of graphic information compression methods with losses and without losses (RLE, LZW, Huffman's method, DEFLATE, JBIG, JPEG, JPEG 2000, Lossless JPEG, fractal and Wawelet) are analyzed in the article. Effective transmission and storage of images in railway communication systems is an important task now. Because large images require large storage resources. This task has become very important in recent years, as the problems of information transmission by telecommunication channels of the transport infrastructure have become urgent. There is also a great need for video conferencing, where the task is to effectively compress video data - because the greater the amount of data, the greater the cost of transmitting information, respectively. Therefore, the use of image compression methods that reduce the file size is the solution to this task. The study highlights the advantages and disadvantages of compression methods. The comparative analysis the basic possibilities of compression methods of graphic information is carried out. The relevance lies in the efficient transfer and storage of graphical information, as big data requires large resources for storage. The practical significance lies in solving the problem of effectively reducing the data size by applying known compression methods.

This article presents the analysis of the international experience of the use of pervious concrete in transport infrastructure. It provides the advantages and disadvantages of the material and the results of personal laboratory tests of relevant concrete samples. The object of the research is the use of pervious concrete in the construction of transport infrastructure. The objective of the paper is to justify the use of pervious concrete in the construction of transport infrastructure by analyzing previous international experience and lab tests of the corresponding concrete samples. Research methods included a analysis of the international and domestic literature, the evaluation of the experience in the use of the pervious concrete, and laboratory tests of the corresponding concrete samples. A review of the world experience connected with research of pervious (draining) concrete, installation and operation of layers of aerodrome surface made of it, proved their technical and economic relevance and effectiveness of their application. Pervious concrete is a material with high open porosity, which provides good sound-absorbing properties and drainage ability together with roughness, smoothness, and transverse friction. These are advantages of pervious concrete pavements, according to foreign studies: a rapid removal of water from the surface of the pavements in case of rain and improved drainage of road and airfield pavements reduce the risk of aquaplaning vehicles and increase traffic safety in rainy weather; increased and stable surface roughness; reduced level of noise provided by vehicles. The draining ability of the pavements makes it almost dry. It also has a high degree of sound absorption. The results of the article can be implemented in various technologies of construction and repair of transport infrastructure. The search for the optimal composition of pervious concrete for its further use in the technology of construction and repair of various objects is the main purpose of predictive assumptions about the development of the object of study.

Subject. The study analyzes generally accepted approaches to assessing the value of companies on the basis of financial statement data of ExxonMobil, Chevron, ConocoPhillips, Occidental Petroleum, Devon Energy, Anadarko Petroleum, EOG Resources, Apache, Marathon Oil, Imperial Oil, Suncor Energy, Husky Energy, Canadian Natural Resources, Royal Dutch Shell, Gazprom, Rosneft, LUKOIL, and others, for 1999—2018. Objectives. The aim is to determine the specifics of using the methods of cost, DFC, and comparative approaches to assessing the value of share capital of oil and gas companies. Methods. The study employs methods of statistical analysis and generalization of materials of scientific articles and official annual reports on the results of financial and economic activities of the largest public oil and gas corporations. Results. Based on the results of a comprehensive analysis, I identified advantages and disadvantages of standard approaches to assessing the value of oil and gas producers. Conclusions. The paper describes pros and cons of the said approaches. For instance, the cost approach is acceptable for assessing the minimum cost of small companies in the industry. The DFC-based approach complicates the reliability of medium-term forecasts for oil prices due to fluctuations in oil prices inherent in the industry, on which the net profit and free cash flow of companies depend to a large extent. The comparative approach enables to quickly determine the range of possible value of the corporation based on transactions data and current market situation.

Neurodegenerative diseases (NDs) including Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis, and Huntington’s disease are incurable and affect millions of people worldwide. The development of treatments for this unmet clinical need is a major global research challenge. Computer-aided drug design (CADD) methods minimize the huge number of ligands that could be screened in biological assays, reducing the cost, time, and effort required to develop new drugs. In this review, we provide an introduction to CADD and examine the progress in applying CADD and other molecular docking studies to NDs. We provide an updated overview of potential therapeutic targets for various NDs and discuss some of the advantages and disadvantages of these tools.

Various methods of collecting data on passenger traffic, their advantages and disadvantages are considered. It is shown that in order to improve the quality of transport services, it is necessary to regularly collect and refine data on passenger traffic. The goals and methods of obtaining information about passenger traffic in the system of municipal passenger transport are indicated. All currently existing methods are divided into three categories: data collection using technical means, data collection with the help of censors and volunteers, and interpretation of fare payments. All the methods presented in the article were compared in terms of labor intensity, costs and accuracy of the results obtained. The advantages and disadvantages of each method are considered. The general structure of an automated system for collecting data on passenger traffic is presented. The necessity of creating a centralized system for collecting and processing data associated with all passenger transport control systems has been substantiated. The tasks solved by this system at all levels of transport services for passengers are shown. Each of the tasks is assigned to one of three service levels: pre-transport, transport and post-transport. It is shown that only solving problems at all levels can ensure high-quality operation of the municipal passenger transport system.
