The dynamic interaction (contact) Introduction. The numerical solution of the given dynamic three-dimensional problem by the finiteelement, boundary-element, and other methods generally involves the principal difficulty associated with degeneration of the contact region into a set of points. Therefore, to solve the problem, we use asymptotic methods.The integral equation of the problem is constructed using the closed form of the fundamental solution of the nonstationary half-space problem (Lamb's problem) [1]. The asymptotic simplification of this equation yields a problem of smaller dimensionality that is solved numerically.As an example, we consider the vertical motion of several smooth round punches with a plane base. Some results have already been reported at conferences [2][3][4].The asymptotic approach to the corresponding static problem was used for the first time by Galin [5]. Argatov and Nazarov [6] obtained a rigorous asymptotic solution for static loading of an elastic body resting on several small supports. In the 1970s, attempts were undertaken to solve dynamic problems with a small parameter, but these solutions contained assumptions [7][8][9]. The bibliography of studies devoted to numerical solutions can be found in [10][11][12][13][14][15][16].1. Fundamental Solution of Lamb's Problem. We use the closed form of the fundamental solution G(t, r) of the nonstationary Lamb's problem [1]. Being caused by a vertical force suddenly applied to the boundary at the moment t = 0, whose magnitude does not change at subsequent times, the vertical displacement of the points at the plane boundary z --0 of the elastic half-space z ~ 0 has the form
The article discusses the currently relevant problem of the quality urban environment, which, as the study has showed, has its own dimensions and characteristics for each person, and the specialists in different fields of knowledge disagree with it and include various indicators and criteria while making a quality assessment. After analyzing the previously developed methods and criteria for assessing the quality of the urban environment, some basic criteria characterizing the degree of suitability of territories, the factors influencing its formation, and the provisions characterizing it, have been formed. The authors proposed several main directions of the large cities’ territory development as well as the recommendations for the urban space design and improvement.
Анализируются проблемы современного российского дизайн-образования с точки зрения его взаимодействия с реальными секторами экономики, содержательного наполнения, кадрового обеспечения. Материалом исследования послужили публикации последних лет, посвященные проблемам развития креативной экономики и формирования новых моделей университетского образования, сайты профильных дизайнерских вузов. Методика исследования опирается на результаты мониторинга вузов 2015-2017 гг., опыт работы авторов в разработке и создании образовательных программ в области дизайна.

ДИЗАЙН И ГОСУДАРСТВО: ПРОСТРАНСТВА ВЗАИМОДЕЙСТВИЯАнализируется опыт государственной поддержки дизайна в контексте его экономических, социальных, культурных возможностей. На примере ряда стран рассматриваются организационные формы участия государства в популяризации и развитии дизайна. Представлен подробный анализ истории организации системы дизайна в СССР в 60-80-е гг. Современные проблемы развития дизайна в России рассмотрены с точки зрения необходимости формирования эффективных механизмов его взаимодействия с государством. Ключевые слова: дизайн; дизайн-мышление; государственная поддержка; перспективы взаимодействия.
