New Directions in Linear Acoustics and Vibration
Linear acoustics was thought to be fully encapsulated in physics texts of the 1950s, but this view has been changed by developments in physics during the last four decades. There is a significant new amount of theory that can be used to address problems in linear acoustics and vibration, but only a small amount of reported work does so. This book is an attempt to bridge the gap between theoreticians and practitioners, as well as the gap between quantum and acoustic. Tutorial chapters provide introductions to each of the major aspects of the physical theory and are written using the appropriate terminology of the acoustical community. The book will act as a quick-start guide to the new methods while providing a wide-ranging introduction to the physical concepts.

Handbook of Himalayan Ecosystems and Sustainability, Volume 1
Volume 1: Spatio-Temporal Monitoring of Forests and Climate is aimed to describe the recent progress and developments of geospatial technologies (remote sensing and GIS) for assessing, monitoring and managing fragile Himalayan ecosystems and their sustainability under climate change. It is a collective research contribution from renowned researchers and academicians working in the Hindu Kush Himalayan (HKH) mountain range. The Himalayas ecosystems have been facing substantial transformation due to severe environmental conditions, land transformation, forest degradation and fragmentation. The authors utilized satellite datasets and algorithms to discuss the intricacy of land use/land cover ch...
Do ultra-poor graduation programs build resilience against droughts? Evidence from rural Ethiopia
We study the role of a multifaceted ultra-poor graduation program in protecting household wellbeing and women’s welfare from the effects of localized droughts in Ethiopia. We use data from a large experimental trial of an integrated livelihood and nutrition intervention that supplemented the consumption support provided by Ethiopia’s Productive Safety Net Program (PSNP), conducted within a sample in which all households were beneficiaries of the PSNP. We match three rounds of household survey data to detailed satellite weather data to identify community-level exposure to droughts. We then exploit random assignment to the graduation program to evaluate whether exposed households show hete...
The SIAM 100-digit Challenge
This book takes readers on a thrilling tour of some of the most important and powerful areas of contemporary numerical mathematics. The tour is organized along the 10 problems of the SIAM 100-Digit Challenge, a contest posed by Nick Trefethen of Oxford University in the January/February 2002 issue of SIAM News. The complete story of the contest as well as a lively interview with Nick Trefethen are also included. The authors, members of teams that solved all 10 problems, show in detail multiple approaches for solving each problem, ranging from elementary to sophisticated, from brute-force to schemes that can be scaled to provide thousands of digits of accuracy and that can solve even larger related problems. The authors touch on virtually every major technique of modern numerical analysis: matrix computation, iterative linear methods, limit extrapolation and convergence acceleration, numerical quadrature, contour integration, discretization of PDEs, global optimization, Monte Carlo and evolutionary algorithms, error control, interval and high-precision arithmetic, and many more.
Sustainable Agriculture for Climate Change Adaptation
The Anthropocene, the time of humans. Never has human influence on the functioning of the planet been greater or in more urgent need of mitigation. Climate change, the accelerated warming of the planet’s surface attributed to human activities, is now at the forefront of global politics. The agriculture sector not only contributes to climate change but also feels the severity of its effects, with the water, carbon and nitrogen cycles all subject to modification as a result. Crop production systems are each subject to different types of threat and levels of threat intensity. There is however significant potential to both adapt to and mitigate climate change within the agricultural sector and reduce these threats. Each solution must be implemented in a sustainable manner and tailored to individual regions and farming systems. This Special Issue evaluates a variety of potential climate change adaptation and mitigation techniques that account for this spatial variation, including modification to cropping systems, Climate-Smart Agriculture and the development and growth of novel crops and crop varieties.
Growing up and Finding Her
Chicagos East Side and its Fox Valley suburbs form the backdrop for Growing Up and Finding Her, a memoir told with the poignancy that only a true story can deliver. Authors Brad and Mary Buettner recount how their lives stream together following the difficult challenges of the 1950s and 60s when their families struggled to overcome poverty, misfortune, and mental illness. The contrast between Brad Buettners small-town environment and Mary Ellen Janowskis big-city experience is one aspect of the story. However, when Brad is six, the death of his sister, Bobby, plunges his family into a spiral of grief and anguish. Meanwhile, Mary battles personal insecurities after being rejected by her closest friend. The pair grapple with life independently until red corduroy, of all things, provides the nudge that blends them together in a union lasting more than forty-five years. In this moving tale, Richard Nixon and Dwight Eisenhower make a brief appearance, and the Vietnam War poses an unexpected obstacle three days before the couples wedding. Growing Up and Finding Her is a story of pain, friendship, and love which unfolds with sincere warmth and humor.
Vom Lösen numerischer Probleme
Dieses Buch führt seine Leser auf einen packenden Streifzug durch die wichtigsten und leistungsfähigsten Bereiche zeitgenössischer numerischer Mathematik. Die Route orientiert sich an den 10 Wettbewerbsaufgaben der "SIAM 10 x 10-Digit Challenge", mit der Nick Trefethen aus Oxford im Frühjahr 2002 seine Kollegen und ihre Doktoranden weltweit herausforderte: jede der in wenigen Sätzen formulierten, hochgradig nichttrivialen Aufgaben verlangt dabei nach der Berechnung der ersten 10 Ziffern einer reellen Zahl. Für jede Aufgabe wird eine Vielfalt von Lösungsmethoden diskutiert und dabei so gut wie jede bedeutendere Technik moderner numerischer Mathematik gestreift. Viele aus der Praxis stammende Hinweise helfen dem Leser, Kompetenzen im Lösen numerischer Probleme zu entwickeln und zu lernen, unter konkurrierenden Methoden eine wohlüberlegte Wahl zu treffen. Der vollständige lauffähige Programmtext aller Verfahren, Beispiele, Tabellen und Figuren steht auf der begleitenden Webseite www.numerikstreifzug.de zur Verfügung.
