Modeling and analysis of power processing systems: Feasibility investigation and formulation of a methodology

A review is given of future power processing systems planned for the next 20 years, and the state-of-the-art of power processing design modeling and analysis techniques used to optimize power processing systems. A methodology of modeling and analysis of power processing equipment and systems has been formulated to fulfill future tradeoff studies and optimization requirements. Computer techniques were applied to simulate power processor performance and to optimize the design of power processing equipment. A program plan to systematically develop and apply the tools for power processing systems modeling and analysis is presented so that meaningful results can be obtained each year to aid the power processing system engineer and power processing equipment circuit designers in their conceptual and detail design and analysis tasks

LDE HERITAGE CONFERENCE on Heritage and the Sustainable Development Goals:

Heritage—natural and cultural, material and immaterial—plays a key role in the development of sustainable cities and communities. Goal 11, target 4, of the Sustainable Development Goals (SDGs) emphasizes the relation between heritage and sustainability. The International LDE Heritage conference on Heritage and Sustainable Development Goals, which took place from 26 to 28 November 2019 at TU Delft in the Netherlands, examined the theories, methodologies, and practices of heritage and SDGs. It asked: How is heritage produced and defined? By whom and in what contexts? What are the conceptions of sustainability, and in what ways are these situational and contextual? How can theoretical findings on heritage and SDGs engage with heritage practice? The conference built on the multidisciplinary expertise of academics in the humanities, social, and spatial sciences, notably the interdisciplinary crossover research program, Design & History, the new theme of Heritage Futures at TU Delft, on active collaboration within the LDE Center for Global Heritage and Development (CGHD), and on heritage-related research conducted by the three partner universities Leiden, Delft and Erasmus in Rotterdam by further associated partners in the consortium and internationally. At TU Delft the research programs bring together different departments and disciplines: architecture, urbanism, history, landscape architecture, real estate and management, and engineering. They aim to further an interdisciplinary understanding of the transformation of the built environment and, through the consistent use of the past, to enable buildings, cities, and landscapes to become more sustainable, resource-efficient, resilient, safe, and inclusive. Researchers from Leiden University approach heritage from a broad variety of disciplinary perspectives, such as archaeology, museum studies, cultural anthropology, and area studies. Heritage research at Leiden University explores processes of heritage creation, and the appreciation and evaluation of material and immaterial heritage, to gain new insights into the cultural constitution of societies. Creating, acknowledging, and contesting heritage tends to be politically sensitive as it involves assertions and redefinitions of memory and identity. History and social studies scholars from Erasmus University in Rotterdam add further insights into heritage practice. This conference created a setting where academics and heritage practitioners could explore these questions from specific perspectives. It brought together 120 academics and practitioners keen to develop their understanding of and their input into heritage conservation, and to increase their contributions towards the development of sustainable cities and communities. The three-day conference combined a variety of formats. Participants engaged in nine academic sessions with peer-reviewed papers, eight roundtables on strategic goals, and six workshops spent applying specific methods and tools
