Analysis of key technologies for creating multisatellite orbital constellations of small spacecraft

One of the key areas of modern world cosmonautics is the development of cluster space systems for various purposes, consisting of a large number of functioning spacecraft. This became possible due to a decrease in the mass of spacecraft due to the creation and use of new materials, the development of electronics and microelectromechanical systems, the use of the group launch method, the development of multi-agent technologies and inter-satellite communication sys-tems. There are projects of systems consisting of a large number of space objects, such as OneWeb, Planet, Starlink, Satellogic, etc. The main classes of devices used to create such multi-satellite systems are small satellites, including the number of micro (up to 100 kg) and nano (up to 10-15 kg) classes, which have significant advantages over heavy space-craft, especially in terms of the timing and cost of their creation. The deployment of multi-satellite constellations, in-cluding hundreds and thousands of satellites, requires fundamentally new approaches to the creation of spacecraft and the system as a whole at all stages of the life cycle. The article discusses the key technologies used to create multi-satellite orbital constellations based on small satellites at different stages of the life cycle - from the early stages of de-sign to the stage of operation and disposal (information from orbit). The experience of a joint project of Samara Univer-sity and the Progress Rocket and Space Center on the creation of a constellation of small spacecraft of the AIST series is presented.

Police Use of Force Escalation and De-escalation: The Use of Systematic Social Observation With Video Footage

As police agencies continue to incorporate body-worn cameras, it becomes increasingly important for researchers and practitioners to explore how to best use these data to better understand patterns of suspect and police behavior. Thus, drawing on a joint project between the Federal Law Enforcement Training Centers and Arizona State University, we expand on prior research demonstrating how social systematic observation (SSO) can be used with video footage to methodically detail the evolving nature of police-suspect encounters. We then illustrate how the data could be evaluated within the framework of escalation and de-escalation using an expanded version of the Resistance Force Comparative Scale (RFCS) first developed and employed in 2001. Finally, we assess the merits and challenges of using video footage to account for suspect and police behaviors in relation to escalation and de-escalation.

Optimization of the Observing Cadence for the Rubin Observatory Legacy Survey of Space and Time: A Pioneering Process of Community-focused Experimental Design

Vera C. Rubin Observatory is a ground-based astronomical facility under construction, a joint project of the National Science Foundation and the U.S. Department of Energy, designed to conduct a multipurpose 10 yr optical survey of the Southern Hemisphere sky: the Legacy Survey of Space and Time. Significant flexibility in survey strategy remains within the constraints imposed by the core science goals of probing dark energy and dark matter, cataloging the solar system, exploring the transient optical sky, and mapping the Milky Way. The survey’s massive data throughput will be transformational for many other astrophysics domains and Rubin’s data access policy sets the stage for a huge community of potential users. To ensure that the survey science potential is maximized while serving as broad a community as possible, Rubin Observatory has involved the scientific community at large in the process of setting and refining the details of the observing strategy. The motivation, history, and decision-making process of this strategy optimization are detailed in this paper, giving context to the science-driven proposals and recommendations for the survey strategy included in this Focus Issue.

Public dialogue as a way to create an inclusive touristic space (on the example of “K. I. Shulzhenko museum” MIC)

The relevance of the article. An important problem of modern Ukrainian society is small number of inclusive spaces, what complicates the process of socialization of young people with disabilities. Prevailing forms of mentality in Ukraine (charitable, administrative, magical) do not provide an opportunity to adequately solve this problem. Only a humanistic, dialogue­based model of mentality will contribute to the creation of a true inclusive in the society. The purpose of the article is to develop proposals for the formation of a local tourism inclusive space on the example of “Klavdiia Shulzhenko Museum”. The methodology. The work is a practice research based on the principles of the philosophy of dialogue, devoted to the search for practical ways to implement a humanistic model of social development in a particular enterprise of tourist infrastructure. The use of general scientific (analysis, synthesis, genera­lization) and special methods (modeling) is deter­mined by the purpose and objectives of the study. The results. Based on the analysis of successful examples of the formation of inclusive space in Ukrainian museums, a step­by­step plan for the transformation of space in the direction of inclusion for the “Klavdiia Shulzhenko Museum”. For the first stage, it is important to create a space for dialogue with the target audience and establish cooperation in the working group. For the second — cooperation for creating the excursions. The next stage is the transformation of infrastructure. The practical significance. The article is a theoretical base for practical museum projects, in which young people with disabilities are actively involved in society, visitors without disabilities will understand that young people with disabilities have high potential and are able to actively participate in society; creates a positive social discourse of acceptance, favorable for the socialization of young people with disabilities. Conclusion. Since the problem of transformation of society in the direction of inclusion is not belongs exclusively for Kharkiv, it is has meaning to use successful world and Ukrainian cases. Since infrastructural problems are the result of existing mental attitudes, they can be solved through changes in mentality (establishing public dialogue), rather than government directives. For Kharkiv, the Municipal Institution of Culture “K. I. Shulzhenko Museum” is a place with significant social and cultural potential. Given the creation of an inclusive space in the museum, it can become one of the outposts of socialization of young people with disabilities, but also — to promote the formation of a positive image of people with disabilities in society. The solution of this task can take the form of cooperation with NGOs and further joint project activities.

History Textbooks as Social Contract: Educational Reform, the Unified History Textbooks and Patriotism in Contemporary Russia

This article examines uniform standardized history education in Russia. It focuses primarily on the process of designing unified national history textbooks in 2013-2017, and also examines the educational reform that followed this process, along with the role of Russian society in the formulation of the textbook’s content. The new historical-cultural criteria—and the Unified textbooks based on them—are considered as a product of social contract as it was revised and approved by the different levels of Russian society: academics, parents, teachers, and government. In essence, the new textbooks are the first joint project made by the government, academics and society in the history of the Russian state. The new history textbooks are regarded as an attempt by the state and society to link Russian history with world history; previously, each discipline was studied separately. It is also an attempt to acknowledge and accept all of Russian history as one historical process of the evolution of Russian statehood, including all successes and achievements as well as black spots and wrongdoings. Although the unified textbooks are the most prudent revision of history in contemporary Russia, however there are several improvements required to redirect textbooks from being simply a tool for the construction of patriotism in schools to also being a mechanism of development of the younger generation’s critical thinking.

Interdisciplinary Gerontology in Higher Education: A Case Study From Soup to Nuts

Through the lens of a multi-year joint project initiated by faculty in Social Work and Digital Arts at Lehman College, the City University of New York's senior college in the Bronx, NY, this paper provides a guide on how to initiate, implement and evaluate interdisciplinary collaborations in gerontology. The paper also suggests ways to ensure that these collaborations can support tenure and promotion processes, funding initiatives, and pedagogical enhancements. The paper focuses on how to make use of campus resources, including departmental Chairs, research offices, and campus-wide committees to identify appropriate collaborators and funding sources; how to nurture productive interdisciplinary relationships, such as clarifying disciplinary expectations and participants' professional needs; and how to maximize return on the effort for tenure and promotion, such as producing publishable content, identifying appropriate opportunities for interdisciplinary publishing and presenting, advocating for interdisciplinary collaborations, and developing interdisciplinary syllabi, an example of evidence-based high-impact pedagogy.

Research and application of numerical models of typhoon surges in China Seas

In this paper, three numerical models of typhoon surge are discussed briefly. The first one is called Five-basin Model (FbM). The second one is called SLOSH (Sea, Lake and Overland Surges from Hurricanes), 5 SLOSH-type basins covering the entire China coastlines were developed in a joint project between authors and Jelesnianski et al. (1992) of U.S.A. The two models have been used in real-time forecasting of typhoon surge. The third one is a new developing model in which inundation using the scheme originated by Flather and Heaps (1975) and astronomical used was included. A multiple nested grid system was developed.

Virtual Education in Chile: An Example of a New Space for Learning

The Virtual Education was born in 2002 from a joint project between the Center for Improvement, Experimentation and Pedagogical Research CPEIP and the Center for Education and Technology Links.CPEIP has developed a line of distance teacher training through the Internet running several courses since 2002, and Links during the last 15 years has dedicated its efforts to provide the access of teachers and students to educational opportunities associated with new technologies of Information and communication. Both institutions decided to combine their efforts and develop a joint project that integrates the CPEIP distance teacher training line, up to now aimed at curriculum updating, different strategies to support the appropriation of ICTs and their curricular integration.

Roller dynamometer particle immission* measurement

Urban traffic is a significant contributor of particulate matter to the environment (Kessinger et al. in https://www.umweltbundesamt.de/sites/default/files/medien/5750/publikationen/hgp_luftqualitaet_2020_bf.pdf, 2021). Hence, there is a high interest in the measured data of roadside immission measurement station. In the federal state Saxony (Germany), the State Office for Environment, Agriculture and Geology (LfULG) is responsible for supervision of the air pollution. In a joint project, the LfULG, the Leibniz Institute for Tropospheric Research (TROPOS) and the Chair of Combustion Engines and Powertrain Systems of the Technical University of Dresden (Lehrstuhl für Verbrennungsmotoren und Antriebssysteme, LVAS) measured the particulate immission* from a selection of passenger cars in an “environment simulation” Weinhold et al. (https://publikationen.sachsen.de/bdb/artikel/36768q, 2020). Especially direct injection spark ignition engines, DISI, without particle filter have a high particulate matter emission, depending on the operating condition. However, an increase of the particulate matter immission due to the rising market penetration of DISI engines was not measurable at the immission measurement stations of LfULG. To investigate the effect of vehicle exhaust emission and immission, an experiment was developed to measure particulate matter immission similar to road conditions on a chassis dynamometer. Five used cars with different engines, exhaust after treatment systems and mileage were evaluated regarding their emissions and particulate immissions. Unexpectedly, a high amount of ultrafine particulate matter smaller 100 nm was found during the emission measurements, although the exhaust emissions were completely extracted to the CVS measurement system. It was concluded that these particles were assignable to break and tire wear. This paper summarizes the most important findings, the complete report is available in Weinhold et al. (https://publikationen.sachsen.de/bdb/artikel/36768q, 2020).
