В статье представлен обзор тематики выпускных квалификационных работ по градостроительству, представленных на Международный смотр-конкурс дипломных проектов архитектурных вузов, проводимый Межрегиональной общественной организацией содействия архитектурному образованию (МООСАО) в 2018 и 2019 годах. Проведенный анализ позволил сформулировать современные направления развития градостроительного знания по смысловым категориям проектов: технологические проекты; стратегические проекты различных уровней; проекты развития урбанизированных территорий; проекты уникальных тематик (освоение космоса, Арктики, концепции города будущего, проекты на территориях зарубежных государств). The article provides an overview of the topics of diploma works on urban planning submitted to the International Review Competition of architectural projects of university graduates held by the Interregional Public Organization for the Promotion of Architectural Education in 2018 and 2019. The analysis made it possible to formulate a generalization of topics into semantic categories: technological projects (technologies for urban planning, environmental-friendly planning, participatory design); strategic projects of various levels (the development of agglomerations and resettlement systems, strategies for the development of cities and historical centers, the modernization of transport systems, as well as projects to form the “nuclei” of economic growth); urban development projects (reconstruction of existing buildings, renovation of communal and warehouse areas of the city, development of disturbed territories, public space projects under the federal program “Formation of a comfortable urban environment”); projects of unique topics (space exploration, the Arctic, the concept of the city of the future, projects in foreign countries).

Multi Mode

Asteroseismology, the study of stellar interiors on the basis of observations of multi-mode stellar oscillations, extends over a large part of the Hertzsprung-Russell diagram. The recently discovered EC14026 stars promise information about the properties of stars on the horizontal branch. Solar-like oscillations excited stochastically by convection have been tentatively identified in a few cases. Promising examples are giant stars, where the expected amplitudes may make ground-based observations of the oscillations relatively straightforward. Major advances can be expected from the upcoming asteroseismic space projects under development or study, including the Eddington mission adopted by ESA as a ‘reserve mission’ in the recent round of selections.

Radiation Testing

Large-scale space projects rely on a thorough Assembly, Integration, and Verification (AIV) process to provide the upmost reliability to spacecraft. While this has not traditionally been the case with CubeSats, their increasing role in space science and technology has led to new verification approaches, including in educational CubeSats. This work describes the integration and verification approach for ISTSat-1, which is an educational CubeSat from the Instituto Superior Técnico in Portugal that partially discards the typical stage-gate approach to spacecraft development in favor of a more iterative approach, allowing for the system-level verification of unfinished prototypes. Early verification included software functional testing on a flatsat model, thermal vacuum and vibration testing on a battery model, ionizing radiation testing on the on-board computer, and non-ionizing radiation (EMC) testing on all subsystems. The testing of functional prototypes at an early development stage led to uncovering system-level errors that would typically require hardware redesign at a later project stage. The team considers the approach to be useful for educational projects that employ a small, co-located team with low non-recurring engineering costs.
