Segregation
by Eric Fong Brent Berry Kumiko ShibuyaSegregation is one of the starkest social realities of contemporary societies. Though often associated with explicitly racist laws of the past, it is a phenomenon that persists to this day and is a crucial element for understanding group relations and the wellbeing of different populations in society. In this book, Eric Fong and Kumiko Shibuya provide a thorough discussion of the evolving complexity of segregation in all its variety and variations. The authors focus not only on past trends and the development of segregation measures, but also the current state of affairs, and demonstrate the connections between the segregation of racial/ethnic groups, immigrant communities, and schools, along with poverty concentration. By taking a wide, cross-cutting view, the authors identify commonalities and differences in the causes, mechanisms, and consequences of segregation. Spatial and social segregation together perpetuate and reinforce the unequal distribution of resources among racial and ethnic groups, which in turn can have positive and negative consequences for individuals and groups. This critical overview of segregation will be a valuable and insightful resource for students of sociology, geography, and ethnic studies, as well as those keen to get a handle on this persistent challenge to equal and inclusive societies.

Seismic Imaging and Inversion
by Robert H. Stolt Arthur B. WegleinExtracting information from seismic data requires knowledge of seismic wave propagation and reflection. The commonly used method involves solving linearly for a reflectivity at every point within the Earth, but this book follows an alternative approach which invokes inverse scattering theory. By developing the theory of seismic imaging from basic principles, the authors relate the different models of seismic propagation, reflection and imaging - thus providing links to reflectivity-based imaging on the one hand and to nonlinear seismic inversion on the other. The comprehensive and physically complete linear imaging foundation developed presents new results at the leading edge of seismic processing for target location and identification. This book serves as a fundamental guide to seismic imaging principles and algorithms and their foundation in inverse scattering theory and is a valuable resource for working geoscientists, scientific programmers and theoretical physicists.
Seismic Performance Analysis of Concrete Gravity Dams (Advanced Topics in Science and Technology in China #57)
by Gaohui Wang Wenbo Lu Sherong ZhangThis book evaluates the seismic performance of concrete gravity dams, considering the effects of strong motion duration, mainshock-aftershock seismic sequence, and near-fault ground motion. It employs both the extended finite element method (XFEM) and concrete damaged plasticity (CDP) models to characterize the mechanical behavior of concrete gravity dams under strong ground motions, including the dam-reservoir-foundation interaction. In addition, it discusses the effects of the initial crack, earthquake direction, and cross-stream seismic excitation on the nonlinear dynamic response to strong ground motions, and on the damage-cracking risk of concrete gravity dams.This book provides a theoretical basis for the seismic performance evaluation of high dams, and can also be used as a reference resource for researchers and graduate students engaged in the seismic design of high dams.
Seismic Waves in Soil Layers: Soil Behaviour During Recent Strong Earthquakes
by Olga V. PavlenkoThis book describes recent studies of soil behaviour in strong ground motion – one of the most important and problematic issues in engineering seismology. Destructive earthquakes worldwide show us the damage of structures located on soil foundations; therefore, reliable and adequate estimations of in situ soil behaviour during strong motion are needed. The effects of soil response proved to be more complicated and diverse than we thought previously. Additionally to well-known amplification of seismic waves in near-surface softer layers, resonant phenomena and nonlinearity of soil response, during the 2011 Tohoku earthquake, we observed soil hardening and generation of abnormally high accelerations. The author suggests a method for studying these effects in situ, to forecast soil behaviour in future earthquakes. The method is based on processing records of seismic vertical arrays, which are widely developed in the world and should help us in understanding soil response during earthquakes.The book is addressed to a wide range of seismologists, geotechnical earthquake engineers and physicists.
Seitenwege in der Mathematikgeschichte: Potentiale und Grenzen alternativer Zugänge
by Christoph KirfelIn diesem Buch werden Methoden aus der Geschichte der Mathematik dargestellt, die nicht zu Standardmethoden geworden sind oder es gar bis in klassische Schulbücher geschafft haben. Diese alternativen Zugänge waren oftmals zum Zeitpunkt ihrer Entstehung aktuell und im Gespräch, haben dann aber gegenüber den heutigen Standardmethoden an Aufmerksamkeit verloren und sind schließlich in Vergessenheit geraten. Oftmals enthalten diese Methoden noch ein ungenutztes Potential: Es lohnt sich, sie weiterzuentwickeln und zu entdecken, wo genau sich ihre Grenzen befinden. Das Buch möchte insbesondere angehenden Lehrkräften einen Blick über die üblichen Lehrinhalte hinaus ermöglichen und inhaltliche Anregungen für die Arbeit mit interessierten und begabten Schülerinnen und Schülern liefern. Archimedes etwa entwickelte eine Methode zur Berechnung des Flächeninhaltes eines Parabelsegmentes, die gewissermaßen ein Stück der Integralrechnung vorwegnimmt. Archimedes' Methode entwickelte sich aber nicht zur Standardmethode, wie man sie in heutigen Lehrbüchern wiederfindet. Dort findet man stattdessen die Methoden, die von Newton und Leibnitz entworfen wurden. Dieses Buch entwickelt die Archimedische Methode weiter und zeigt ihr „Restpotential“ auf: Andere Kurven, nicht nur Parabeln, lassen sich ähnlich angreifen und es ist interessant und lehrreich zu sehen, wie weit sich Archimedes' Methode entwickeln lässt und wo sie dann letztlich an ihre Grenzen stößt.
Selberg Zeta Functions and Transfer Operators
by Markus Szymon FraczekThis book presents a method for evaluating Selberg zeta functions via transfer operators for the full modular group and its congruence subgroups with characters. Studying zeros of Selberg zeta functions for character deformations allows us to access the discrete spectra and resonances of hyperbolic Laplacians under both singular and non-singular perturbations. Areas in which the theory has not yet been sufficiently developed, such as the spectral theory of transfer operators or the singular perturbation theory of hyperbolic Laplacians, will profit from the numerical experiments discussed in this book. Detailed descriptions of numerical approaches to the spectra and eigenfunctions of transfer operators and to computations of Selberg zeta functions will be of value to researchers active in analysis, while those researchers focusing more on numerical aspects will benefit from discussions of the analytic theory, in particular those concerning the transfer operator method and the spectral theory of hyperbolic spaces.
Selbstbestimmter Tourismus am Beispiel der Kanarischen Inseln: Abhängigkeiten reduzieren – Zielkonflikte entschärfen – Diversifikation ermöglichen

Selbstbestimmter Tourismus bedeutet, eine bewusste Entscheidung für Zukunftsszenarien der Inseln zu entwickeln und abgestimmt zu sein zwischen Unternehmertum, Politik und Wissenschaft, um gemeinsam mit den nationalen und internationalen Reiseunternehmen geeignete Strategien zum Wohle des gesamten Tourismus-Netzwerkes „Kanarische Inseln“ zu finden.
Selbstwirksamkeit, Leistung und Calibration in Mathematik: Eine Studie zum Einfluss von Aufgabenmerkmalen und Feedback zu Studienbeginn (Studien zur Hochschuldidaktik und zum Lehren und Lernen mit digitalen Medien in der Mathematik und in der Statistik)
by Angela LagingDie vorliegende Arbeit widmet sich dem Problem der Selbsteinschätzung, insbesondere Überschätzung, in Mathematik bei Studienanfängerinnen. Die quantitative Studie untersucht den Einfluss von Aufgabenmerkmalen und Feedback auf die mathematische Leistung, Selbstwirksamkeitserwartung und Calibration bei Studienanfänger/innen wirtschaftswissenschaftlicher Studiengänge. Die Untersuchungen zeigen, dass vor allem Aufgabenmerkmale wie die curriculare Wissensstufe und der Bearbeitungsumfang die Selbstwirksamkeitserwartung und die tatsächlich erbrachte Leistung auf unterschiedliche Weise beeinflussen. Innerhalb des ersten Studiensemesters verändern sich bei der untersuchten Kohorte Selbstwirksamkeitserwartung und Leistung, wodurch eine deutliche Reduzierung der Selbstüberschätzung erreicht wurde. Inwieweit das Feedback dazu beigetragen hat, kann methodisch bedingt nicht eindeutig festgestellt werden. Die Autorin Angela Laging ist Lehrerin für Mathematik und Kunst an einem Gymnasium.

Selected Aspects of Fractional Brownian Motion
by Ivan NourdinFractional Brownian motion (fBm) is a stochastic process which deviates significantly from Brownian motion and semimartingales, and others classically used in probability theory. As a centered Gaussian process, it is characterized by the stationarity of its increments and a medium- or long-memory property which is in sharp contrast with martingales and Markov processes. FBm has become a popular choice for applications where classical processes cannot model these non-trivial properties; for instance long memory, which is also known as persistence, is of fundamental importance for financial data and in internet traffic. The mathematical theory of fBm is currently being developed vigorously by a number of stochastic analysts, in various directions, using complementary and sometimes competing tools. This book is concerned with several aspects of fBm, including the stochastic integration with respect to it, the study of its supremum and its appearance as limit of partial sums involving stationary sequences, to name but a few. The book is addressed to researchers and graduate students in probability and mathematical statistics. With very few exceptions (where precise references are given), every stated result is proved.

Selected Problems of Solid Mechanics and Solving Methods (Advanced Structured Materials #204)
by Alexander Ya. Grigorenko Holm Altenbach Victor A. Eremeyev Vladimir M. Nazarenko Viacheslav Bogdanov Roman M. KushnirThis book examines new approaches for the estimation of errors in approximate theories. Numerical and analytical methods in mechanics often require the establishment of a set of basic equations, and various approaches exist to create approximate theories from them. The problem is that nobody knows the boundaries of the estimation of errors in approximate theories. This book presents new approaches to overcome this problem and to provide the reader with suitable methods for the relevant field, including a representation of different scientific schools and different countries. These new methods are helping to solve many problems not only in analytical Mechanics but also in Physics, Mathematics, and Civil Engineering.
