The article is dedicated to the work of S.Yu. Witte by rail. The period of his work in the joint-stock company of the South-Western Railways, his journalistic and expert activity in the railway field at this time is considered. The article provides an overview of Witte’s views on the system of railway freight tariffs formulated in his book Principles of Railway Tariffs for the Carriage of Goods (1883) and analyzed his views on the private and government railway facilities

The problem of regulators (controllers) design is extremely relevant in connection with the penetration into all technological areas of the methods of precise control of objects with feedback. Such devices are being more and more used, which increases the variety of controlled objects. This list includes all new objects of robotics and technological setups, which have much more complex mathematical models. One of the most urgent problems in this area is control of nonstationary objects. Parameters of mathematical model of these objects are given with some uncertainty, but not in fixed values, i.e. by only intervals of their possible changes. If the intervals are too wide, adaptive systems have to be designed, but if they are not too wide, then one can try to find a universal regulator setting that will be sufficiently effective for all ratios of the model parameters within the acceptable intervals of their changes. The paper proposes a new method of the numerical optimization of regulator for finding such a setting for the worst object model that is for the worst combination of all variable parameters. Finding the worst model is also carried out by a numerical optimization method, in which a combination of model parameters is found where the best regulator gives the worst result. The problem is proposed to solve in several optimization cycles with alternation of objective functions. The technique has been well illustrated by a numerical example.
Nowadays, the NearNorth of Russia undergoes a fateful epoch. The processes of destruction of the old world order in economic, social and cultural relations is not only continuing, but increasing its pace. The omnipresent destruction is manifested through the depopulation of villages and small towns, further decline in agricultural production, "consolidation" (actually closing) of educational institutions and health care centers, and the degradation of infrastructure. The compressed social space of the Middle North of Russia is shrinking in concentric circles around the regional centers, increasing the vastness of social vacuum and the white space, with the latter being gradually occupied by the mutating natural forms. In addition, yet another (opposite) trend can be identified. It is associated with the escalation of migration amongst the dwellers of the large cities, especially megalopolises, to rural areas.
Extensive development of Russian cities, especially Moscow and St. Petersburg, has revealed serious social problems that had previously not been fully taken into account. In particular, the rapid escalation and exacerbation of social problems determine the quality of life in cities. From one perspective, Moscow and St. Petersburg are represented as thriving metropolises possessing a whole set of such social attractors as rich and comfortable residential buildings, shopping malls with international brands, best restaurants, medical facilities and other requisites of the upper classes. However, parallel to these features, the quality of life in metropolitan areas is determined by such parameters as the deteriorating environmental conditions, increase in street (and other types of) crime, unsolvable traffic conditions which reduce inner-city mobility to a minimum, and the decline of anti-terrorist security.
In the Middle North of Russia, especially in the Kostroma region, one particular trend became evident: there has been a transition from the seasonal migration to dachas towards the ‘settled’ migration related not only to the summer recreation, but also to the industrial activity in the framework of modern technologies. Specifically, modern forms of labor in the field of information technology were initially (and still remain to be) exterritorial in nature. Those working with data tend to be indifferent to the location of their job – what is important to them is a point of connection to the network and a portal for entry into hyperspace.
This paper studies the innovation strategy of Russian Railways, the biggest transport company in the world. Russian Railways has chosen a strategy of international science, technology and innovation (STI) cooperation outside their own network. This strategy is a novel approach for Russian State-owned enterprises (SOE). Based on the analysis of innovation development program and interviews with managers, the paper studies the company’s experience with the chosen strategy. Thereby, the paper enhances the understanding of innovation processes in major public service companies which are crucial for the socio-economic processes inside and outside national boundaries.
Abstract—This article proposes the order of description and classification of digital traces of the attacking object and new methodical recommendations for creating a protection function to counter cyber attacks.
The highest rates of use of Internet technologies and, first of all, the Internet of things, in various fields of human activity, impose new requirements to ensure information security of objects of risk. Cyber attacks can cause huge material and financial damage. The complexity of countering cyber attacks is primarily due to their high technology. Therefore, only the use of intelligent means and systems of counteraction can be a real protection against malicious intrusion.

This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
