An arbitrary compact-support initial datum for the Korteweg–de Vries equation asymptotically splits into solitons and a radiation tail, moving in opposite direction. We give a simple method to predict the number and amplitudes of resulting solitons and some integral characteristics of the tail using only conservation laws

This book reflects the results of research and operational experiences of the Federal State Budgetary Entity “National research center “Institute named after N.E. Zhukovsky” in management of scientific and technological development. This book outlines structure and main processes of this management system as well as main elements of its working tools. Besides general methodological developments of the Center the book briefly represents also particular results of their application for Russian aircraft industry scientific-technological development management.For instance, the highlights of long-term forecast for aircraft science and technological development created by the Center on its own methodology are described. The particular attention is paid to new organizational solutions in the sphere of research and development, those give our country the chance for parity with global competitors in spite of smaller scopes and current backlog in many scientific and technical fields. These ones are cross-sectoral technology transfer and cross-sectoral integration of research and development result. Meanwhile Center’s research and development findings frequently go beyond sectoral applied science. They result in recommendations on improving legal and regulatory support for research and development, structure of scientific and manufacturing organizations. These suggestions are also outlined in this book.

Many micro-level models of information processes in social networks consider either a change in the information-psychological state of agents (opinions, beliefs, attitudes) or a change in their observable behavior (actions). The goal in this paper is to develop and analyze a complex agent-based model of opinion dynamics that describes the dynamics of agents’ beliefs and the process of performing actions by agents. The issues of reaching consensus and polarizing opinions of agents are investigated.

Nowadays, verification of the initial data for designing the information base of the NPP Automated Process Control System is a guarantee of the correct operation of the NPP Automated Process Control System itself. For this verification, exact and approximate methods are usually applied. Each method provides desirable results for an appropriate problem type. Exact methods are more suitable for solving this problem. The article presents a solution algorithm in terms of checking both the structure and the content of initial data, including a complete parsing of the Kraftwerk Kennzeichen System code with the study of all its sectors. A list of the most common inconsistencies is also provided.
