Download or read book Deep Learning Based Forward Modeling and Inversion Techniques for Computational Physics Problems written by Yinpeng Wang and published by CRC Press. This book was released on 2023-07-06 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates in detail the emerging deep learning (DL) technique in computational physics, assessing its promising potential to substitute conventional numerical solvers for calculating the fields in real-time. After good training, the proposed architecture can resolve both the forward computing and the inverse retrieve problems. Pursuing a holistic perspective, the book includes the following areas. The first chapter discusses the basic DL frameworks. Then, the steady heat conduction problem is solved by the classical U-net in Chapter 2, involving both the passive and active cases. Afterwards, the sophisticated heat flux on a curved surface is reconstructed by the presented Conv-LSTM, exhibiting high accuracy and efficiency. Additionally, a physics-informed DL structure along with a nonlinear mapping module are employed to obtain the space/temperature/time-related thermal conductivity via the transient temperature in Chapter 4. Finally, in Chapter 5, a series of the latest advanced frameworks and the corresponding physics applications are introduced. As deep learning techniques are experiencing vigorous development in computational physics, more people desire related reading materials. This book is intended for graduate students, professional practitioners, and researchers who are interested in DL for computational physics.

Download or read book International Aid and Sustainable Development in North Korea written by Sojin Lim and published by Taylor & Francis. This book was released on 2023-06-22 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines international aid in North Korea, in particular the ongoing policy of withholding aid, through the lens of the impact on the general population to present an argument for sustainable development. Focusing on the human rights of North Koreans and presenting a case for the use of aid as a provision for social change, it explores an alternative narrative to the existing long-drawn-out rhetoric of ‘denuclearisation-first’. The book’s scope includes evaluations of the causes of international sanctions and their impact, the Kim regime’s mitigation of sanctions through marketisation and a digital economy as well as barriers to aid monitoring and the reason for the absence of any mass anti-regime movement. It also posits that North Korea is a fragile state but cloaked by the image of a strong regime. The book succinctly demonstrates that the key to unlocking the potential of North Korea’s ‘cloaked society’ does not lie in sanctions, but is to be found in engagement with development aid. As such it will appeal to students of Korean Studies, Development Studies, Asian Politics and International Relations. Chapters 1 and 7 of this book are freely available as a downloadable Open Access PDF at http://www.taylorfrancis.com under a Creative Commons [Attribution-Non Commercial-No Derivatives (CC-BY-NC-ND)] 4.0 license.

Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic exploration is one of the earliest and most widely used geophysical exploration techniques. Electromagnetic methods, such as magnetotelluric (MT), audio magnetotelluric (AMT), transient electromagnetic method (TEM), and controlled source electromagnetic method (CSEM), have made a great contribution to industrialization and urbanization by discovering underground deposits of various resources. Driven by the latest progress in electronics and intelligent algorithms, electromagnetic exploration is developing at a high speed. Many challenges faced by traditional geophysical methods are now solvable. Emerging sensing technology and signal processing technology greatly improves the accuracy of electromagnetic methods in many applications. At the same time, such technologies promoted the development of new geophysical theories and methods.

Download or read book Monitoring Early Warning and Mitigation of Natural and Engineered Slopes volume III written by Wen Nie and published by Frontiers Media SA. This book was released on 2024-08-20 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural and engineered slopes are widely distributed worldwide, including mountain slopes, highway slopes, mine slopes, reservoir dams, etc. These slopes could become unstable due to natural factors or human activities, causing catastrophic loss of life and infrastructure destruction. Therefore, these slopes require constant monitoring to provide early warning and enable mitigation. Advanced monitoring equipment, information technology, and multidisciplinary interaction theories have created new opportunities and challenges in this discipline. Recently, advanced monitoring devices, information technologies, and multidisciplinary intersection theories have contributed to the monitoring, early warning and mitigation of natural and engineered slopes. However, effective and efficient monitoring, precise early warning, low-cost and low-time-consuming remediation, and reliable risk assessment remain obstacles. This Research Topic aims to present the most recent innovative advancements and state-of-the-art natural and engineered slope monitoring, early warning, mitigation, and risk assessment.

Download or read book The Ancient World in Alternative History and Counterfactual Fictions written by Alberto J. Quiroga Puertas and published by Bloomsbury Publishing. This book was released on 2024-08-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing in turn on history, powerful individuals, under-represented voices and the arts, the essays in this collection cover a wide variety of modern and contemporary narrative fiction from Jo Walton and L. Sprague De Camp to T. S. Chaudhry and Catherynne M. Valente. Chapters look into the question of chance versus determinism in the unfolding of historical events, the role individuals play in shaping a society or occasion, and the way art and literature symbolise important messages in counterfactual histories. They also show how uchronic narratives can take advantage of modern literary techniques to reveal new and relevant aspects of the past, giving voices to marginalised minorities and suppressed individuals of the ancient world. Counterfactual fiction and uchronic narratives have been largely up until now the domain of literary critics. However, these modes of literature are here analysed by scholars of Ancient History, Egyptology and Classics, shedding important new light on how cultures of the ancient world have been (and still are) perceived, and to what extent our conceptions of the past are used to explore alternate presents and futures. Alternate history entices the imagination of the public by suggesting hypothetical scenarios that never occurred, underlining a latent tension between reality and imagination, and between determinism and contingency. This interest has resulted in a growing number of publications that gauge the impact of what-if narratives, and this one is the first to give scholars of the ancient world centre-stage.

Download or read book Advances and Applications of Passive Seismic Source Characterization written by Lei Li and published by Frontiers Media SA. This book was released on 2023-10-09 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Source characterization is a fundamental task of passive seismic monitoring. Spatial-temporal evolution of both, point sources and finite-fault source, provides essential information for timely seismic hazard management and advanced analysis of the seismicity in the monitored areas. In the last few decades, the rise of dense seismic arrays, increase of high-performance computing resources, and development of advanced array-based techniques lead to studies using recorded wavefields in great detail. Full waveform inversion can invert passive seismic source parameters with an iterative framework, which connects the delay-and-sum imaging technique and kernel-based inversion strategy. Moreover, emerging technologies like distributed acoustic sensing and machine learning also have great potential in advancing passive seismic imaging and source characterization. Besides, non-earthquake sources and ambient noise, as unconventional and passive sources, are also undergoing rapid development in infrastructure monitoring and subsurface imaging, due to the emergence of sensitive sensors and modern techniques like seismic interferometry.
