    The NASA Ares I Crew Launch Vehicle is being designed to support missions to the International Space Station (ISS), to the Moon, and beyond. The Ares I is undergoing design and development utilizing commercial-off-the-shelf tools and hardware when applicable, along with cutting edge launch technologies and state-of-the-art design and development. In support of the vehicle s design and development, the Ares Functional Fault Analysis group was tasked to develop an Ares Vehicle Diagnostic Model (AVDM) and to demonstrate the capability of that model to support failure-related analyses and design integration. One important component of the AVDM is the Upper Stage (US) Thrust Vector Control (TVC) diagnostic model-a representation of the failure space of the US TVC subsystem. This paper first presents an overview of the AVDM, its development approach, and the software used to implement the model and conduct diagnostic analysis. It then uses the US TVC diagnostic model to illustrate details of the development, implementation, analysis, and verification processes. Finally, the paper describes how the AVDM model can impact both design and ground operations, and how some of these impacts are being realized during discussions of US TVC diagnostic analyses with US TVC designers

    Microgrids have recently emerged as the building block of a smart grid, combining distributed renewable energy sources, energy storage devices, and load management in order to improve power system reliability, enhance sustainable development, and reduce carbon emissions. At the same time, rapid advancements in sensor and metering technologies, wireless and network communication, as well as cloud and fog computing are leading to the collection and accumulation of large amounts of data (e.g., device status data, energy generation data, consumption data). The application of big data analysis techniques (e.g., forecasting, classification, clustering) on such data can optimize the power generation and operation in real time by accurately predicting electricity demands, discovering electricity consumption patterns, and developing dynamic pricing mechanisms. An efficient and intelligent analysis of the data will enable smart microgrids to detect and recover from failures quickly, respond to electricity demand swiftly, supply more reliable and economical energy, and enable customers to have more control over their energy use. Overall, data-intensive analytics can provide effective and efficient decision support for all of the producers, operators, customers, and regulators in smart microgrids, in order to achieve holistic smart energy management, including energy generation, transmission, distribution, and demand-side management. This book contains an assortment of relevant novel research contributions that provide real-world applications of data-intensive analytics in smart grids and contribute to the dissemination of new ideas in this area

    ca. 200 words; this text will present the book in all promotional forms (e.g. flyers). Please describe the book in straightforward and consumer-friendly terms. [There is ever more research on smart cities and new interdisciplinary approaches proposed on the study of smart cities. At the same time, problems pertinent to communities inhabiting rural areas are being addressed, as part of discussions in contigious fields of research, be it environmental studies, sociology, or agriculture. Even if rural areas and countryside communities have previously been a subject of concern for robust policy frameworks, such as the European Union’s Cohesion Policy and Common Agricultural Policy Arguably, the concept of ‘the village’ has been largely absent in the debate. As a result, when advances in sophisticated information and communication technology (ICT) led to the emergence of a rich body of research on smart cities, the application and usability of ICT in the context of a village has remained underdiscussed in the literature. Against this backdrop, this volume delivers on four objectives. It delineates the conceptual boundaries of the concept of ‘smart village’. It highlights in which ways ‘smart village’ is distinct from ‘smart city’. It examines in which ways smart cities research can enrich smart villages research. It sheds light on the smart village research agenda as it unfolds in European and global contexts.

    Монографія рекомендована до друку вченою радою СумДУ Протокол № 5 від 17.11.2022Економічні успіхи розвинених країн, як показує практика, досягаються завдяки розвитку освіти та наукових досліджень, які швидко освоюються. Освіту людей можна розглядати як ефективний фактор економічного зростання. Водночас це найважливіша складова людського капіталу, який акумулюється в суспільстві і стає основним економічним ресурсом. Проте її довгостроковий розвиток потребує державної підтримки. Досвід надання державної підтримки та розвитку освіти в передових країнах світу може бути корисним для України, яка потребує реформування системи освіти та побудови інноваційної економіки. Але тут потрібно чітко уявляти собі проблеми, які виникнуть, і шукати шляхи їх вирішення. Вирішення проблем освітнього простору наразі ускладнено повномасштабною війною та пандемічним станом, за якого COVID-19 отримав постійну «прописку» у сучасному світі. Актуальність дослідження визначається зростанням проблем в освіті, зумовлених зовнішніми та внутрішніми факторами, важливістю забезпечення якісної освіти на всіх рівнях та підтримки міжвузівської співпраці. Російська військова агресія, часткове знищення навчального фонду, велика кількість переселенців та багатогодинні відключення електроенергії унеможливлюють процес якісної ініціації, як наживо, так і онлайн. Ця монографія покликана акцентувати увагу на складних і, водночас, важливих викликах освітнього середовища, які, у свою чергу, можуть змінити майбутнє нашої країни.Экономический успех развитых стран, как показывает практика, достигается за счет развития образования и научных исследований, которые быстро осваиваются. Образование людей можно рассматривать как действенный фактор экономического роста. В то же время это важнейшая составляющая человеческого капитала, которая накапливается в обществе и становится основным экономическим ресурсом. Однако его долгосрочное развитие требует государственной поддержки. Опыт государственной поддержки и развития образования в передовых странах мира может быть полезен для Украины, которая нуждается в реформировании системы образования и построении инновационной экономики. Но здесь нужно четко представлять проблемы, которые возникнут, и находить пути их решения. Решение проблем образовательного пространства в настоящее время осложнено полномасштабной войной и состоянием пандемии, при котором COVID-19 получил постоянную «прописку» в современном мире. Актуальность исследования определяется ростом количества проблем в образовании, вызванных внешними и внутренними факторами, важностью обеспечения качественного образования на всех уровнях и поддержки межвузовского сотрудничества. Российская военная агрессия, частичное уничтожение образовательного фонда, большое количество мигрантов и многочасовые отключения электроэнергии делают невозможным процесс качественной инициации как вживую, так и онлайн. Данная монография призвана акцентировать внимание на сложных и в то же время важных задачах образовательной среды, которые, в свою очередь, могут изменить будущее нашей страны.The economic success of developed countries, as practice shows, is achieved due to the development of education and scientific research, which are quickly mastered. Education of people can be considered as an effective factor of economic growth. At the same time, it is the most important component of human capital, which accumulates in society and becomes the main economic resource. However, its long-term development requires state support. The experience of providing state support and development of education in advanced countries of the world can be useful for Ukraine, which needs to reform the education system and build an innovative economy. But here you need to clearly imagine the problems that will arise and find ways to solve them. Solutions to the problems of the educational space are currently complicated by a full-scale war and the pandemic state, under which COVID-19 has received a permanent "registration" in the modern world. The relevance of the study is determined by the growing number of problems in education caused by external and internal factors, the importance of ensuring quality education at all levels and supporting inter-university cooperation. Russian military aggression, the partial destruction of the educational fund, a large number of migrants and many hours of power outages make the process of qualitative initiation impossible, both live and online. This monograph is designed to focus attention on complex and, at the same time, important challenges of the educational environment, which, in turn, can change the future of our country

    Our world is facing many challenges, such as poverty, hunger, resource shortage, environmental degradation, climate change, and increased inequalities and conflicts. To address such challenges, the United Nations proposed the Sustainable Development Goals (SDG), consisting of 17 interlinked global goals, as the strategic blueprint of world sustainable development. Nevertheless, the implementation of the SDG framework has been very challenging and the COVID-19 pandemic has further impeded the SDG implementation progress. Accelerated efforts are needed to enable all stakeholders, ranging from national and local governments, civil society, private sector, academia and youth, to contribute to addressing this dilemma. This volume of the Climate Change and Environmental Sustainability book series aims to offer inspiration and creativity on approaches to sustainable development. Among other things, it covers topics of COVID-19 and sustainability, environmental pollution, food production, clean energy, low-carbon transport promotion, and strategic governance for sustainable initiatives. This book can reveal facts about the challenges we are facing on the one hand and provide a better understanding of drivers, barriers, and motivations to achieve a better and more sustainable future for all on the other. Research presented in this volume can provide different stakeholders, including planners and policy makers, with better solutions for the implementation of SDGs.

    Approach to identify product and process state drivers in manufacturing systems using supervised machine learning

    Get PDF
    The developed concept allows identifying relevant state drivers of complex, multi-stage manufacturing systems holistically. It is able to utilize complex, diverse and high-dimensional data sets which often occur in manufacturing applications and integrate the important process intra- and inter-relations. The evaluation was conducted by using three different scenarios from distinctive manufacturing domains (aviation, chemical and semiconductor). The evaluation confirmed that it is possible to incorporate implicit process intra- and inter-relations on process as well as programme level through applying SVM based feature ranking. The analysis outcome presents a direct benefit for practitioners in form of the most important process parameters and state characteristics, so-called state drivers, of a manufacturing system. Given the increasing availability of data and information, this selection support can be directly utilized in, e.g., quality monitoring and advanced process control
