Fixed Point of the Parabolic Renormalization Operator

by Oscar E. Lanford III Michael Yampolsky

This monograph grew out of the authors' efforts to provide a natural geometric description for the class of maps invariant under parabolic renormalization and for the Inou-Shishikura fixed point itself as well as to carry out a computer-assisted study of the parabolic renormalization operator. It introduces a renormalization-invariant class of analytic maps with a maximal domain of analyticity and rigid covering properties and presents a numerical scheme for computing parabolic renormalization of a germ, which is used to compute the Inou-Shishikura renormalization fixed point. Inside, readers will find a detailed introduction into the theory of parabolic bifurcation, Fatou coordinates, Écalle-Voronin conjugacy invariants of parabolic germs, and the definition and basic properties of parabolic renormalization. The systematic view of parabolic renormalization developed in the book and the numerical approach to its study will be interesting to both experts in the field as well as graduate students wishing to explore one of the frontiers of modern complex dynamics.

Fixed-Time Cooperative Control of Multi-Agent Systems

by Qing-Long Han Zongyu Zuo Boda Ning

This monograph presents new theories and methods for fixed-time cooperative control of multi-agent systems. Fundamental concepts of fixed-time stability and stabilization are introduced with insightful understanding. This book presents solutions for several problems of fixed-time cooperative control using systematic design methods. The book compares fixed-time cooperative control with asymptotic cooperative control, demonstrating how the former can achieve better closed-loop performance and disturbance rejection properties. It also discusses the differences from finite-time control, and shows how fixed-time cooperative control can produce the faster rate of convergence and provide an explicit estimate of the settling time independent of initial conditions. This monograph presents multiple applications of fixed-time control schemes, including to distributed optimization of multi-agent systems, making it useful to students, researchers and engineers alike.

Fixpunkte und Nullstellen: Klartext für Nichtmathematiker (essentials)

by Guido Walz

Dieses Buch vermittelt in leicht zugänglicher Sprache Methoden zur numerischen Berechnung von Fixpunkten und Nullstellen reeller Funktionen mithilfe von Iterationsverfahren. Insbesondere das Banach-Verfahren zur Fixpunktbestimmung sowie das Newton-Verfahren, eines der besten numerischen Verfahren zur Nullstellenberechnung von Funktionen, werden ausführlich dargestellt. In einem abschließenden Kapitel werden Anwendungen dieser Verfahren behandelt. Unter anderen geht es dabei um die beliebig genaue Berechnung von Wurzeln jeder Ordnung. Da sich der Text ausdrücklich (auch) an Nichtmathematiker und Nichtmathematikerinnen wendet, ist er bewusst in allgemein verständlicher Sprache gehalten, um die Leser nicht durch übertriebene Fachsprache abzuschrecken; schließlich soll es sich ebenfalls laut Untertitel um „Klartext“ handeln. Zahlreiche Beispiele machen die einzelnen Themen leicht verständlich.

Flash Computation and EoS Modelling for Compositional Thermal Simulation of Flow in Porous Media (Springer Theses)

by Duncan Paterson

This book investigates a wide range of phase equilibrium modelling and calculation problems for compositional thermal simulation. Further, it provides an effective solution for multiphase isenthalpic flash under the classical framework, and it also presents a new flash calculation framework for multiphase systems, which can handle phase equilibrium and chemical reaction equilibrium simultaneously. The framework is particularly suitable for systems with many phases and reactions. In this book, the author shows how the new framework can be generalised for different flash specifications and different independent variables. Since the flash calculation is at the heart of various types of compositional simulation, the findings presented here will promote the combination of phase equilibrium and chemical equilibrium calculations in future simulators, aiming at improving their robustness and efficiency.

Flatland

by by Edwin A. Abbott William F. Lindgren Thomas F. Banchoff by Edwin A. Abbott William F. Lindgren Thomas F. Banchoff

Flatland, Edwin Abbott's story of a two-dimensional universe, as told by one of its inhabitants who is introduced to the mysteries of three-dimensional space, has enjoyed an enduring popularity from the time of its publication in 1884. This fully annotated edition enables the modern-day reader to understand and appreciate the many 'dimensions' of this classic satire. Mathematical notes and illustrations enhance the usefulness of Flatland as an elementary introduction to higher-dimensional geometry. Historical notes show connections to late-Victorian England and to classical Greece. Citations from Abbott's other writings as well as the works of Plato and Aristotle serve to interpret the text. Commentary on language and literary style includes numerous definitions of obscure words. An appendix gives a comprehensive account of the life and work of Flatland's remarkable author.

Flatland: A Romance of Many Dimensions

by Thomas Banchoff Edwin Abbott Abbott

In 1884, Edwin Abbott Abbott wrote a mathematical adventure set in a two-dimensional plane world, populated by a hierarchical society of regular geometrical figures-who think and speak and have all too human emotions. Since then Flatland has fascinated generations of readers, becoming a perennial science-fiction favorite. By imagining the contact of beings from different dimensions, the author fully exploited the power of the analogy between the limitations of humans and those of his two-dimensional characters. A first-rate fictional guide to the concept of multiple dimensions of space, the book will also appeal to those who are interested in computer graphics. This field, which literally makes higher dimensions seeable, has aroused a new interest in visualization. We can now manipulate objects in four dimensions and observe their three-dimensional slices tumbling on the computer screen. But how do we interpret these images? In his introduction, Thomas Banchoff points out that there is no better way to begin exploring the problem of understanding higher-dimensional slicing phenomena than reading this classic novel of the Victorian era.

Flatland: A Romance of Many Dimensions (Dover Thrift Editions: Classic Novels)

by Edwin A. Abbott

This masterpiece of science (and mathematical) fiction is a delightfully unique and highly entertaining satire that has charmed readers for more than 100 years. The work of English clergyman, educator and Shakespearean scholar Edwin A. Abbott (1838-1926), it describes the journeys of A. Square, a mathematician and resident of the two-dimensional Flatland, where women-thin, straight lines-are the lowliest of shapes, and where men may have any number of sides, depending on their social status.Through strange occurrences that bring him into contact with a host of geometric forms, Square has adventures in Spaceland (three dimensions), Lineland (one dimension) and Pointland (no dimensions) and ultimately entertains thoughts of visiting a land of four dimensions—a revolutionary idea for which he is returned to his two-dimensional world. Charmingly illustrated by the author, Flatland is not only fascinating reading, it is still a first-rate fictional introduction to the concept of the multiple dimensions of space. "Instructive, entertaining, and stimulating to the imagination." — Mathematics Teacher.

Flaws and Fallacies in Statistical Thinking

by Stephen K. Campbell

This book was written with a dual purpose: first, the author was motivated to relieve his distress over the faulty conclusions drawn from the frequent misuse of relatively simple statistical tools such as percents, graphs, and averages. Second, his objective was to create a nontechnical book that would help people make better-informed decisions by increasing their ability to judge the quality of statistical evidence. This volume achieves both, serving as a supplemental text for students taking their first course in statistics, and as a self-help guide for anyone wishing to evaluate statistical evidence more judiciously.The sequence of topics corresponds with that of many beginning textbooks in statistics, and the terminology and treatment of subjects are based on the assumption that readers have had little or no prior exposure to statistics or formal mathematics. The author examines the perils of statistical ignorance, some problems in basic measurement and definition, and the prevalence of meaningless statistics, far-fetched estimates, cheating charts, and accommodating averages. He explains common pitfalls of statistical thinking such as ignoring dispersion, inflating percentages, drawing improper comparisons, jumping to conclusions, and making errors of probability and induction. Playful in tone but scrupulously accurate in nature, this text is equally valuable in and out of the classroom.

Flexibility of Group Actions on the Circle (Lecture Notes in Mathematics #2231)

by Sang-Hyun Kim Mahan Mj Thomas Koberda

In this partly expository work, a framework is developed for building exotic circle actions of certain classical groups. The authors give general combination theorems for indiscrete isometry groups of hyperbolic space which apply to Fuchsian and limit groups. An abundance of integer-valued subadditive defect-one quasimorphisms on these groups follow as a corollary. The main classes of groups considered are limit and Fuchsian groups. Limit groups are shown to admit large collections of faithful actions on the circle with disjoint rotation spectra. For Fuchsian groups, further flexibility results are proved and the existence of non-geometric actions of free and surface groups is established. An account is given of the extant notions of semi-conjugacy, showing they are equivalent. This book is suitable for experts interested in flexibility of representations, and for non-experts wanting an introduction to group representations into circle homeomorphism groups.

Flexible Approaches in Data, Information and Knowledge Management

by Olivier Pivert Sławomir Zadrożny

This volume showcases contributions from internationally-known researchers in the field of information management. Most of the approaches presented here make use of fuzzy logic, introduced by L. A. Zadeh almost 50 years ago, which constitute a powerful tool to model and handle gradual concepts. What all of these contributions have in common is placing the user at the center of the information system, be it for helping him/her to query a data set, to handle imperfect information, or to discover useful knowledge from a massive collection of data. Researchers working in data and knowledge management will greatly benefit from this collection of up-to-date studies. This may be also an invaluable source of information for postgraduate students interested in advanced information management techniques.

Flexible Imputation of Missing Data (Chapman & Hall/CRC Interdisciplinary Statistics)

by Stef Van Buuren

Missing data pose challenges to real-life data analysis. Simple ad-hoc fixes, like deletion or mean imputation, only work under highly restrictive conditions, which are often not met in practice. Multiple imputation replaces each missing value by multiple plausible values. The variability between these replacements reflects our ignorance of the true (but missing) value. Each of the completed data set is then analyzed by standard methods, and the results are pooled to obtain unbiased estimates with correct confidence intervals. Multiple imputation is a general approach that also inspires novel solutions to old problems by reformulating the task at hand as a missing-data problem. This is the second edition of a popular book on multiple imputation, focused on explaining the application of methods through detailed worked examples using the MICE package as developed by the author. This new edition incorporates the recent developments in this fast-moving field. This class-tested book avoids mathematical and technical details as much as possible: formulas are accompanied by verbal statements that explain the formula in accessible terms. The book sharpens the reader’s intuition on how to think about missing data, and provides all the tools needed to execute a well-grounded quantitative analysis in the presence of missing data.

Flexible Regression and Smoothing: Using GAMLSS in R (Chapman & Hall/CRC The R Series)

by Robert Rigby Vlasios Voudouris Gillian Heller Mikis Stasinopoulos Fernanda De Bastiani

This book is about learning from data using the Generalized Additive Models for Location, Scale and Shape (GAMLSS). GAMLSS extends the Generalized Linear Models (GLMs) and Generalized Additive Models (GAMs) to accommodate large complex datasets, which are increasingly prevalent. GAMLSS allows any parametric distribution for the response variable and modelling all the parameters (location, scale and shape) of the distribution as linear or smooth functions of explanatory variables. This book provides a broad overview of GAMLSS methodology and how it is implemented in R. It includes a comprehensive collection of real data examples, integrated code, and figures to illustrate the methods, and is supplemented by a website with code, data and additional materials.

Flexible and Generalized Uncertainty Optimization: Theory and Approaches (Studies in Computational Intelligence #696)

by Weldon A. Lodwick Luiz L. Salles-Neto

This book presents the theory and methods of flexible and generalized uncertainty optimization. Particularly, it describes the theory of generalized uncertainty in the context of optimization modeling. The book starts with an overview of flexible and generalized uncertainty optimization. It covers uncertainties that are both associated with lack of information and are more general than stochastic theory, where well-defined distributions are assumed. Starting from families of distributions that are enclosed by upper and lower functions, the book presents construction methods for obtaining flexible and generalized uncertainty input data that can be used in a flexible and generalized uncertainty optimization model. It then describes the development of the associated optimization model in detail. Written for graduate students and professionals in the broad field of optimization and operations research, this second edition has been revised and extended to include more worked examples and a section on interval multi-objective mini-max regret theory along with its solution method.

Flexibles Rechnen im Grundschulverlauf: Eine Längsschnittstudie zur Förderung und Entwicklung flexibler Vorgehensweisen beim Addieren und Subtrahieren (Mathematikdidaktik im Fokus)

by Anna Körner

​Die Entwicklung von Flexibilität beim Rechnen gilt seit vielen Jahren als zentrales Ziel des Arithmetikunterrichts der Grundschule. Dennoch belegen die Ergebnisse empirischer Studien zu Vorgehensweisen von Kindern, dass viele Schüler*innen einen Hauptrechenweg bevorzugen und selten flexibel agieren. Flexibilität scheint sich also nicht automatisch zu entwickeln, sondern muss gezielt gefördert werden. Aufbauend auf Ergebnissen anderer Studien wurde für die vorliegende Untersuchung eine Unterrichtskonzeption zur kontinuierlichen Förderung von Flexibilität vom ersten bis zum vierten Schuljahr entwickelt und umgesetzt. Im Rahmen dieser längsschnittlichen Studie wurden die Vorgehensweisen der Schüler*innen beim Addieren und Subtrahieren sieben Mal im Projektzeitraum in leitfadengestützten Einzelinterviews erfasst, um anhand qualitativer Inhaltsanalyse mit darauf folgender Fallkontrastierung und Typenbildung charakteristische Entwicklungen im Grundschulverlauf rekonstruieren zu können. Alszentrales Ergebnis wird eine Typologie zur Einordnung der Vorgehensweisen beim Lösen von Additions- und Subtraktionsaufgaben vorgestellt, anhand derer Fort- und Rückschritte im Entwicklungsverlauf dokumentiert werden können.

Flight Safety Management: Quantitative and AI Approaches (Studies in Systems, Decision and Control #228)

by Chi-Bin Cheng Huan-Jyh Shyur

This book offers a comprehensive overview of using artificial intelligence and quantitative approaches in many phases of flight safety management, from proactive assessment of potential risks of flights before taking-off to automatic analysis of occurred flight events, for commercial airlines. Flight safety is commonly the core values of airlines. Serious flight disasters always bring tremendous impacts and losses to the industry and the society; thus, airlines and the authorities always treat the issues of flight safety management as the first priority. It presents the information systems that assist the safety staff and managers to adopt preventive operations or to analyze the critical factors or operations that cause a flight event. Such information systems were developed based on artificial intelligence and quantitative approaches, including fuzzy logic, expert systems, deep learning, decision-making methods, reliability theory, and data mining. After introducing the flight safety management practice and common programs, as well as basic artificial intelligence and quantitative approaches, the book describes in detail the information systems we have developed and provides instructions for flight safety practitioners to implement such information systems in their organizations. Case studies collected from the cooperated airline are also presented.

Flipped Classroom im Mathematikunterricht der Sekundarstufe I am Beispiel der Satzgruppe des Pythagoras: Eine empirische Untersuchung fachbezogener Gestaltungsvarianten und deren Auswirkungen auf den Lernerfolg

by Jennifer Rothe

Das Medium des Lernvideos rückt zunehmend ins Interesse von Lehrkräften zur Vermittlung mathematischer Inhalte. Lernvideos entfalten ihren größten Nutzen, wenn sie inhaltlich ergänzend zu traditionellen Unterrichtsmedien verwendet werden, wie beispielsweise im Rahmen der Flipped-Classroom-Methode. Zur konkreten Umsetzung geflippten Mathematikunterrichts existiert allerdings kein Standardverfahren. Daher werden in dieser Arbeit zunächst theoriegeleitet fachbezogene Gestaltungselemente geflippten Fachunterrichts konzeptualisiert. Diese beziehen sich auf das Anspruchsniveau des Lernvideoinhalts (gering oder erhöht), die Art dieses Videoinhalts (Einführungs- oder Lösungsbeispielvideos) sowie die Art des Übens in der Präsenzphase (erweitertes Einüben im eigenen Tempo oder Bearbeitung eines Vertiefungsproblems). Diese werden in einer Mixed-Methods-Studie hinsichtlich ihrer Eignung zur Gestaltung von Mathematikunterricht und des zu erwartenden Lernerfolgs im Vergleich zum Regelunterricht untersucht. Die Ergebnisse zeigen einige besonders geeignete Gestaltungsvarianten geflippten Mathematikunterrichts für die Schulpraxis auf, mit denen Teile der Lernenden einen verbesserten Lernerfolg im Vergleich zum Regelunterricht zeigen.

Floating Point Numerics for Games and Simulations

by Nima Badizadegan

Floating point is ubiquitous in computers, where it is the default way to represent non-integer numbers. However, few people understand it. We all see weird behavior sometimes, and many programmers treat it as a mystical and imprecise system of math that just works until it sometimes doesn’t. We hear that we shouldn’t trust floating point with money, we know that 0.1 + 0.2 does not equal 0.3, and “NaN” shows up in our logs when things break. We rarely hear why any of this is the case, and less about what to do about it.This book pulls back the veil on floating point and shows how this number system we program with every day works. It discusses how to leverage the number system for common calculations, particularly in graphics and simulations, and avoid pitfalls. Further, we will review methods that can give you either better performance or better accuracy on tasks like numerical integration and function approximation, so you can learn to make the right tradeoffs in your programs.This book builds upon a basic knowledge of calculus and linear algebra, working with illustrative examples that demonstrate concepts rather than relying on theoretical proofs. Along the way, we will learn why Minecraft has struggled with boat physics and what the heck John Carmack was thinking with Quake III’s infamous fast reciprocal square root algorithm. By the end of the book, you will be able to understand how to work with floating point in a practical sense, from tracking down and preventing error in small calculations to choosing numerical building blocks for complex 3D simulations. Gives insight into how and why floating-point math works Describes how floating-point error arises and how to avoid it Surveys numerical methods important to graphics and numerical simulations Includes modern techniques to apply to your numerical problems Shows how to hack the floating-point numbers to compute faster and more accurately

Florence Nightingale David: A Passionate Probabilist, Statistician, Historian, and Leader

by Amanda L. Golbeck

This book examines Florence Nightingale David's life, contributions, and relationships throughout her life, as well as her subsequent legacy. Florence Nightingale David (1909-1993) was the first woman professor in the world's first academic statistics department, served in various British ministries during the war from 1939-1945, and was one of the first women to chair a statistics department in a research university. In this biography, the life stories of David are used as a vehicle to explore a variety of questions surrounding culture and engagement in the statistical sciences. What does it take to succeed in an environment that is not inclusive of your demographic? How can stories be used to bring technical material to life for students and other learners? And how can a nontraditional leader succeed in challenging boundaries and moving an enterprise forward?
