Frontotemporal Lobar Degeneration and Amyotrophic Lateral Sclerosis: Genetics, Clinical and Pathological Features, and Disease Mechanisms

Multiphysics Methods and Analysis Applied to Nuclear Reactor Systems

Multiphysics modeling and simulation in nuclear engineering is critical for the design, analysis, and operation of advanced nuclear reactors. These simulations encapsulate the intricate interactions between various physical phenomena, such as fluid dynamics, heat transfer, and nuclear reactions, providing a virtual yet robust framework for reactor assessment. This approach significantly reduces reliance on expensive and potentially hazardous experimental testing. Ensuring the validity of these models through experimental data and precise uncertainty quantification is paramount to align with the stringent safety and regulatory standards of the nuclear industry. High-fidelity computational methods thus play a pivotal role in advancing nuclear reactor safety and performance while navigating the complexities of regulatory compliance and operational efficiency in a rapidly evolving technological landscape. This Research Topic is dedicated to presenting the forefront of research and providing deep insights into the pivotal role that sophisticated simulations play in advancing nuclear reactor technologies. The Topic will explore the frontier of innovative computational methods that facilitate the integration of diverse physical phenomena. These multiphysics models are essential tools in the design and safety analysis of nuclear reactors, helping to predict and optimize performance under a wide array of operating conditions, reduce conservatism compared to more traditional methods, and gain physical insight that is currently unavailable through experimental data. A central theme of this collection is the rigorous experimental validation that these models undergo to confirm their accuracy and reliability. Such validation efforts are vital for ensuring that the simulations can be confidently used in critical decision-making processes. Additionally, this Topic will address the intricacies of uncertainty quantification within these models, a process that is becoming increasingly important as it directly impacts regulatory standards and the approval of new reactor designs. By bringing together this knowledge, this collection will illuminate the ongoing developments and challenges in the field, while emphasizing the importance of precision and rigor in the modeling of advanced nuclear systems. Submissions are encouraged from a diverse international pool of contributors, including industry professionals, academic researchers, and research laboratory experts, to foster a multidisciplinary dialogue that addresses both present challenges and future needs in this rapidly growing field.

Wind Tunnel Testing of High-Rise Buildings

Since the 1960s, wind tunnel testing has become a commonly used tool in the design of tall buildings. It was pioneered, in large part, during the design of the World Trade Center Towers in New York. Since those early days of wind engineering, wind tunnel testing techniques have developed in sophistication, but these techniques are not widely understood by the designers using the results. As a direct result, the CTBUH Wind Engineering Working Group was formed to develop a concise guide for the non-specialist. The primary goal of this guide is to provide an overview of the wind tunnel testing process for design professionals. This knowledge allows readers to ask the correct questions of their wind engineering consultants throughout the design process. This is not an in-depth guide to the technical intricacies of wind tunnel testing, it focusses instead on the information the design community needs, including: a unique methodology for the presentation of wind tunnel results to allow straightforward comparison of results from different wind tunnel laboratories. advice on when a tall building is likely to be sufficiently sensitive to wind effects to benefit from a wind tunnel test background for assessing whether design codes and standards are applicable details of the types of tests that are commonly conducted descriptions of the fundamentals of wind climate and the interaction of wind and tall buildings This unique book is an essential guide for all designers of tall buildings, and anyone else interested in the process of wind tunnel testing for tall buildings.
