Long-Term Ecosystem Changes in Riparian Forests (Ecological Research Monographs)
by Hitoshi SakioThis open access book presents and analyzes the results of more than 30 years of long-term ecological research in riparian forest ecosystems with the aim of casting light on changes in the dynamics of riparian forests over time. The research, focusing on the Ooyamazawa riparian forest, one of the remaining old-growth forests in Japan, has yielded a number of interesting outcomes. First, it shows that large-scale disturbances afford various trees opportunities for regeneration and are thus the driving force for the coexistence of canopy trees in riparian forests. Second, it identifies changes in reproductive patterns, highlighting that seed production has in fact quantitatively increased over the past two decades. Third, it describes the decline in forest floor vegetation caused by deer grazing and reveals how this decline has affected bird and insect populations. The book illustrates the interconnectedness of phenomena within an ecosystem and the resultant potential for cascade effects and also stresses the need for long-term ecological studies of climate change impacts on forests. It will be of interest to both professionals and academics in the field of forest science.
Long-Term Health Consequences of Exposure to Burn Pits in Iraq and Afghanistan
by Committee on the Long-Term Health Consequences of Exposure to Burn Pits in Iraq AfghanistanMany veterans returning from the conflicts in Iraq and Afghanistan have health problems they believe are related to their exposure to the smoke from the burning of waste in open-air "burn pits" on military bases. Particular controversy surrounds the burn pit used to dispose of solid waste at Joint Base Balad in Iraq, which burned up to 200 tons of waste per day in 2007. The Department of Veterans Affairs asked the IOM to form a committee to determine the long-term health effects from exposure to these burn pits. Insufficient evidence prevented the IOM committee from developing firm conclusions. This report, therefore, recommends that, along with more efficient data-gathering methods, a study be conducted that would evaluate the health status of service members from their time of deployment over many years to determine their incidence of chronic diseases.

Long-Term Non-Operating Reliability of Electronic Products (Electronic Packaging Ser.)
by Judy PechtIn today's electronic environment, operating reliability for continued daily use of electronic products is essential. This book discusses the reliability of products that lie dormant for long periods of time and are subject to stresses such as humidity, ionic contaminants, temperature, radiation, shock, and vibration. Non-operating reliability is especially critical for life-saving electronic products such as fire alarm systems, standby power sources, and burglar alarms. Air bags in automobiles, earthquake alarm systems, and radiation warning systems in nuclear power plants are also covered. This physics-of-failure approach is also important to maintaining defense hardware such as missiles and munitions systems which often lie dormant for years before being deployed on very short notice

Long-Term Stewardship and the Nuclear Weapons Complex: The Challenge Ahead
by Katherine N. Probst Michael H. McGovernDecades of U.S. nuclear weapons production have exacted a heavy environmental toll. The Department of Energy estimates that cleaning up waste and contamination resulting from production activities will cost over $150 billion. Yet even once that money is spent, these sites will need long-term attention to assure protection of human health and the environment. In the authors' words, stewardship refers to 'institutions, information, and strategies needed to ensure protection of people and the environment, both in the short and the long term.' Probst and McGovern make a compelling case for establishing a formal program of long-term stewardship for contaminated sites. Their report details the requirements of a successful stewardship program and discusses the daunting technical and political challenges facing such efforts, including the designation of an institutional home for key stewardship functions. The legacy of environmental damage is considerable; hazardous waste disposal, radioactive waste, and contaminated facilities are among the problems that will remain after DOE cleanup efforts are complete. Stewardship planning, according to Probst and McGovern, must start now.
Long-Term Strength of Materials: Reliability Assessment and Lifetime Prediction of Engineering Structures
by Alexander Chudnovsky Kalyan SehanobishThe physics of fracture processes, which includes Fracture mechanics, is crucial for understanding the longevity and reliability of any structure, from fracture initiation to propagation and final catastrophic failure. This textbook introduces the thermodynamics of irreversible processes along with entropy to address the time dependency of fracture. Working from observations of structural failure, the book identifies the principal failure types such as brittle fracture, with considerations of solo crack initiation and crack propagation associated with collective distributed damage. The other type is ductile fracture, when a crack blunts immediately on the application of stress resulting in large deformation. The book then addresses the life of a structure in a specific environment and load condition, using irreversible thermodynamics and the entropy criterion to address cooperative fracture and novel statistical Fracture mechanics to address solo fracture. Applies well-established concepts from mechanics, absent in contemporary Fracture mechanics Uses novel concepts of mechanics, irreversible thermodynamics, and statistical Fracture mechanics The book is ideal for graduate students and design engineers in civil and materials engineering, as well as mechanical and chemical engineering. Students using the book need no more than basic college-level mechanics, mathematics, and statistics knowledge.
Long-Term Structural Health Monitoring by Remote Sensing and Advanced Machine Learning: A Practical Strategy via Structural Displacements from Synthetic Aperture Radar Images (SpringerBriefs in Applied Sciences and Technology)
by Carlo De Michele Alireza Entezami Bahareh BehkamalThis book offers an in-depth investigation into the complexities of long-term structural health monitoring (SHM) in civil structures, specifically focusing on the challenges posed by small data and environmental and operational changes (EOCs). Traditional contact-based sensor networks in SHM produce large amounts of data, complicating big data management. In contrast, synthetic aperture radar (SAR)-aided SHM often faces challenges with small datasets and limited displacement data. Additionally, EOCs can mimic the structural damage, resulting in false errors that can critically affect economic and safety issues. Addressing these challenges, this book introduces seven advanced unsupervised learning methods for SHM, combining AI, data sampling, and statistical analysis. These include techniques for managing datasets and addressing EOCs. Methods range from nearest neighbor searching and Hamiltonian Monte Carlo sampling to innovative offline and online learning frameworks, focusing on data augmentation and normalization. Key approaches involve deep autoencoders for data processing and novel algorithms for damage detection. Validated using simulated data from the I-40 Bridge, USA, and real-world data from the Tadcaster Bridge, UK, these methods show promise in addressing SAR-aided SHM challenges, offering practical tools for real-world applications. The book, thereby, presents a comprehensive suite of innovative strategies to advance the field of SHM.

Longwall Mining, 3rd Edition
by Syd S. PengIn the past 13 years since the publication of Longwall Mining, 2nd edition in 2006, although there have been no major changes in longwall mining technology and operations, many incremental developments in the whole system as well as various subsystems of the existing longwall mining operational technologies as detailed in the 2nd edition have been added to this edition. Major developments are automation, and health and safety technology, as well as equipment reliability, thereby greatly increasing productivity and cutting cost. In particular, the longwall system can now run automatically cut by cut forever without operators' intervention provided that the geology allows it. Other health and safety features such as LASC, personal proximity detection, color lighting, automatic shield water sprays and remote shearer control are fully operational. There are more than 7000 sensors installed in current longwall mining systems. The big data obtained and fast communication technology have been fully utilized to improve and solve operational problems in real time. Those features are fully documented in the new edition. In pursuit of high productivity and cutting cost, life cycle management that increases equipment reliability has been implemented by OEM. Automation improvement such as tail-end automatic chain tensioner greatly extends AFC chain's service life. Other incremental improvements including dust and methane controls, entry development, panel design and face move are addressed. Additional operational issues such as extension of panel width and compatibility test are also discussed. Since the last plow longwall mine was closed in 2018, the chapter on plow longwalling has been dropped and in its place Automation of Longwall Components and System is added. Also, a new chapter Longwall Top Coal Caving Mining (LTCC) is added due to its successful application in Australia since 2005. Longwall Mining, 3rd edition will be of interest to professionals and academics in the field of mining engineering specifically, serving both as a reference work and an (under)graduate textbook, but will also interest civil, geomechanical and geological engineers and rock mechanics professionals, as well as coal operators, mining consultants, researchers, equipment manufacturers, and government regulators.
