Science, Humanism, and Religion

Science, Humanism, and Religion

Matthias Jung

Springer Nature Switzerland AG
2020
nidottu
In the human quest for orientation vis-à-vis personal life and comprehensive reality the worldviews of religionists and humanists offer different answers, and science also plays a crucial role. Yet it is the ordinary, embodied experience of meaningful engagement with reality in which all these cultural activities are rooted. Human beings have to relate themselves to the entirety of their lives to achieve orientation. This relation involves a non-methodical, meaningful experience that exhibits the crucial features for understanding worldviews: it comprises cognition, volition, and emotion, is embodied, action-oriented, and expressive. From this starting-point, religious and secular worldviews articulate what is experienced as ultimately meaningful. Yet the plurality and one-sidedness of these life stances necessitates critical engagement for which philosophy provides indispensable means. In the end, some worldviews can be ruled out, but we are still left with a plurality of genuine options for orientation.

Mathematical Analysis of the Navier-Stokes Equations

Mathematical Analysis of the Navier-Stokes Equations

Matthias Hieber; James C. Robinson; Yoshihiro Shibata

Springer Nature Switzerland AG
2020
nidottu
This book collects together a unique set of articles dedicated to several fundamental aspects of the Navier–Stokes equations. As is well known, understanding the mathematical properties of these equations, along with their physical interpretation, constitutes one of the most challenging questions of applied mathematics. Indeed, the Navier-Stokes equations feature among the Clay Mathematics Institute's seven Millennium Prize Problems (existence of global in time, regular solutions corresponding to initial data of unrestricted magnitude). The text comprises three extensive contributions covering the following topics: (1) Operator-Valued H8-calculus, R-boundedness, Fourier multipliers and maximal Lp-regularity theory for a large, abstract class of quasi-linear evolution problems with applications to Navier–Stokes equations and other fluid model equations; (2) Classical existence, uniqueness and regularity theorems of solutions to the Navier–Stokes initial-value problem, along with space-time partial regularity and investigation of the smoothness of the Lagrangean flow map; and (3) A complete mathematical theory of R-boundedness and maximal regularity with applications to free boundary problems for the Navier–Stokes equations with and without surface tension. Offering a general mathematical framework that could be used to study fluid problems and, more generally, a wide class of abstract evolution equations, this volume is aimed at graduate students and researchers who want to become acquainted with fundamental problems related to the Navier–Stokes equations.

Situational Diversity

Situational Diversity

Matthias Klückmann

Springer Nature Switzerland AG
2020
sidottu
At a time when diversity is taking an increasingly prominent place in public and academic debate, Situational Diversity offers a new perspective by understanding diversity framed in the local context, characterised through different forms of social differentiation. Based on ethnographic fieldwork and archival research on migration-driven diversity in two neighbourhoods in Stuttgart (Germany) and Glasgow (United Kingdom), the book presents a concept that takes into account the contingent and emergent nature of social differentiation while at the same time explaining the stability of modes of differentiation. The comparative approach provides a nuanced analysis of how diversity in urban environments occurs as a result of locally, socially and temporally specific practices. In this book, Klückmann discusses how social work, city administration and volunteer work prefigure positions and relations of people in the context of migration. Thus,it will appeal to students and scholars of social and cultural anthropology, European ethnology, sociology, human/cultural geography, cultural studies in addition to practitioners in the fields of intercultural relations, social and public policy as well as urban development.

Multi-time Wave Functions

Matthias Lienert; Sören Petrat; Roderich Tumulka

Springer Nature Switzerland AG
2020
nidottu
The natural generalization of the quantum-mechanical N-particle wave function to relativistic space-time is a function of N space-time points, and thus of N time variables. This book, based on a collection of lectures given at a spring school in Tübingen in 2019, provides an accessible and concise introduction to the recent development of the theory of multi-time wave functions, their use in quantum field theory, their relation to detection probabilities, and the mathematical question of consistency of their time evolution equations. The book is intended for advanced students and researchers with an interest in relativity and quantum physics.

Intellectual Property, Design Innovation, and Entrepreneurship

Intellectual Property, Design Innovation, and Entrepreneurship

Matthias Hillner

Springer Nature Switzerland AG
2021
sidottu
This book focuses on intellectual property (IP) in the context of product innovation and design-led start-up management. A distinguished feature is that it analyses innovation-related scenarios within their continuously changing contexts. IP is discussed in relation to the way in which its value changes over time as a venture matures. The book reveals how IP strategies can enhance a start-up’s survival prospects and its growth potential if they are connected systematically to other business development attributes. Being mainly addressed to enterprising designers, it may also support business administration programmes, innovation hubs, design educators, incubator managers, as well as business coaches and IP attorneys who support creatives and inventors. All in all, this book offers a unique and timely strategic guidance in the field of design and innovation management. “Design and design rights have long been overlooked in the plethora of studies on the links between IPR and innovation. Matthias Hillner’s thoughtful and eloquent journey provides a contemporary and meaningful analysis which will no doubt assist governments, economists, academics and designers’ better understanding of design in the context of successful business strategies and IPR. Given design’s significant contribution to global economies, I am confident it will offer much needed guidance.”Dids Macdonald OBE, founder CEO of Anticopying in Design (ACID)"This is an immensely practical book for designers and entrepreneurs who want to understand the issues of IP, product innovation, and business development. With clear explanations, many vivid examples, and strategically useful tips, it will be a valuable resource for creative minds at all levels of experience. A serious book but written with a sensitive touch on how to protect new ideas."

Antisemitism in Reader Comments

Antisemitism in Reader Comments

Matthias J. Becker

Springer Nature Switzerland AG
2021
sidottu
This book examines the most frequent form of Jew-hatred: Israel-related antisemitism. After defining this hate ideology in its various manifestations and the role the internet plays in it, the author explores the question of how Israel-related antisemitism is communicated and understood through the language used by readers in below-the-line comments. Drawing on a corpus of over 6,000 comments from traditionally left-wing news outlets The Guardian and Die Zeit, the author examines both implicit and explicit comparisons made between modern-day Israel and both colonial Britain and Nazi Germany. His analyses are placed within the context of resurgent neo-nationalism in both countries, and it is argued that these instances of antisemitism perform a multi-faceted role in absolving guilt, re-writing history, and reinforcing in-group status. This book will be of interest not only to linguistics scholars, but also to academics in fields such as internet studies, Jewish studies, hate speech and antisemitism.

Graphs and Discrete Dirichlet Spaces

Graphs and Discrete Dirichlet Spaces

Matthias Keller; Daniel Lenz; Radoslaw K. Wojciechowski

Springer Nature Switzerland AG
2021
sidottu
The spectral geometry of infinite graphs deals with three major themes and their interplay: the spectral theory of the Laplacian, the geometry of the underlying graph, and the heat flow with its probabilistic aspects. In this book, all three themes are brought together coherently under the perspective of Dirichlet forms, providing a powerful and unified approach. The book gives a complete account of key topics of infinite graphs, such as essential self-adjointness, Markov uniqueness, spectral estimates, recurrence, and stochastic completeness. A major feature of the book is the use of intrinsic metrics to capture the geometry of graphs. As for manifolds, Dirichlet forms in the graph setting offer a structural understanding of the interaction between spectral theory, geometry and probability. For graphs, however, the presentation is much more accessible and inviting thanks to the discreteness of the underlying space, laying bare the main concepts while preserving the deep insights ofthe manifold case. Graphs and Discrete Dirichlet Spaces offers a comprehensive treatment of the spectral geometry of graphs, from the very basics to deep and thorough explorations of advanced topics. With modest prerequisites, the book can serve as a basis for a number of topics courses, starting at the undergraduate level.

Environmental Knowledge, Race, and African American Literature

Environmental Knowledge, Race, and African American Literature

Matthias Klestil

Springer Nature Switzerland AG
2023
sidottu
This open access book suggests new ways of reading nineteenth-century African American literature environmentally. Combining insights from ecocriticism, African American studies, and Foucauldian theory, Matthias Klestil examines forms of environmental knowledge in African American writing ranging from antebellum slave narratives and pamphlets to Charlotte Forten’s journals, Booker T. Washington’s autobiographies, and Charles W. Chesnutt’s short fiction. The volume highlights how literary forms of environmental knowledge in the African American tradition were shaped by the histories of slavery and race, mainstream environmental writing traditions, and African American forms of expression and intertextuality. Turning to the Underground Railroad, debates over education and home-building, and the aesthetics of the pastoral and the georgic, Environmental Knowledge, Race, and African American Literature provides an original perspective on the African American ecoliterary traditionthat uncovers new facets of canonical and understudied texts and offers new directions for ecocriticism and African American studies.

Data Management in Machine Learning Systems

Data Management in Machine Learning Systems

Matthias Boehm; Arun Kumar; Jun Yang

Springer International Publishing AG
2019
nidottu
Large-scale data analytics using machine learning (ML) underpins many modern data-driven applications. ML systems provide means of specifying and executing these ML workloads in an efficient and scalable manner. Data management is at the heart of many ML systems due to data-driven application characteristics, data-centric workload characteristics, and system architectures inspired by classical data management techniques. In this book, we follow this data-centric view of ML systems and aim to provide a comprehensive overview of data management in ML systems for the end-to-end data science or ML lifecycle. We review multiple interconnected lines of work: (1) ML support in database (DB) systems, (2) DB-inspired ML systems, and (3) ML lifecycle systems. Covered topics include: in-database analytics via query generation and user-defined functions, factorized and statistical-relational learning; optimizing compilers for ML workloads; execution strategies and hardware accelerators;data access methods such as compression, partitioning and indexing; resource elasticity and cloud markets; as well as systems for data preparation for ML, model selection, model management, model debugging, and model serving. Given the rapidly evolving field, we strive for a balance between an up-to-date survey of ML systems, an overview of the underlying concepts and techniques, as well as pointers to open research questions. Hence, this book might serve as a starting point for both systems researchers and developers.

A New Kirchhoff-Love Beam Element and its Application to Polymer Mechanics

A New Kirchhoff-Love Beam Element and its Application to Polymer Mechanics

Matthias C. Schulz

Springer International Publishing AG
2022
sidottu
The novel finite element formulations fall into the category of geometrically exact Kirchhoff-Love beams. A prominent characteristic of this category is that the absence of shear deformation is strongly enforced by removing two degrees of freedom. Further, the corresponding beam theories exhibit not only translational but also rotational degrees of freedom and their configurations thus form a non-additive and non-commutative space. Sophisticated interpolation schemes are required that need to be tested not only for locking, spatial convergence behavior, and energy conservation, but also for observer invariance and path-independence. For the three novel beam element formulations all these properties are analytically and numerically studied and confirmed, if applicable. Two different rotation parameterization strategies are employed based on the well-known geodesic interpolation used in many Simo-Reissner beams and the lesser known split into the so-called \textit{smallest rotation} and a torsional part. Application of the former parameterization results in a mixed finite element formulation intrinsically free of locking phenomena. Additionally, the first geometrically exact Kirchhoff-Love beam element is presented, which strongly enforces inextensibility by removing another degree of freedom. Furthermore, the numerical efficiency of the new beam formulations is compared to other beam elements that allow for or suppress shear deformation. When modeling very slender beams, the new elements offer distinct numerical advantages.Standard molecular dynamics simulations, which are commonly used to study polymers, suffer from a lack of a careful mathematical basis and the use of an expensive explicit time integration scheme. To circumvent these shortcomings and to be able to simulate stretching experiments on relevant time scales, the problem is described by a stochastic partial differential equation, which can be solved using the finite element method with a backward Euler temporal discretization. In detail, the polymer is represented by a Kirchhoff-Love beam with a linear elastic constitutive model. Inertial and electrostatic forces are neglected. It is deformed by a distributed load mimicking collisions with molecules of the surrounding fluid. Naturally, this load heavily fluctuates over time and space and mean values need to be computed in a Monte Carlo manner. To vastly speed up the fitting process to experimental data in a Bayesian framework, a surrogate model based on a Gaussian process is set up, which directly computes the mean values for given material parameters. The uncertainties and correlations of the material parameters are studied and compared to the literature.

The Dortmund Lumbar Load Atlas

The Dortmund Lumbar Load Atlas

Matthias Jäger

Springer International Publishing AG
2023
sidottu
This handbook supports the identification of inappropriate work design in manual materials handling and thus the prevention of overloading the body and of the development of health disorders. The approach at hand, The Dortmund Lumbar Load Atlas, is focussed exclusively on biomechanical aspects of loading, overload criteria and signs of overloading in the form of verifiable low-back diseases due its strikingly frequently affectedness. Manual materials handling is understood to be the holding, lifting or lowering, pulling or pushing as well as carrying of load objects and thus the application of forces mostly with one or both hands on the item handled. Due to the biomechanical similarity, special handling tasks are also addressed, such as shoveling bulk material, transporting goods via wheelbarrow and moving people manually in the care sector. The book aims to promote interest in biomechanical approaches and provides information to all persons involved in the design, evaluation and redesign of manual materials handling, e.g. ergonomists, occupational physicians, orthopaedists, employers or researchers, lecturers and students. This handbook enables analysis of manual materials handlings regarding potential lumbar overload and contains the following:a comprehensive collection of data on lumbar load in typical manual materials handling activities—a load register on interbranch activities,synopses of previously analysed biomechanically challenging occupational activities—a load register on branch-specific activities,explanations of the methodological approach to predicting moments and forces as well as their components in relation to the lumbar spine via biomechanical modelling andcriteria for the evaluation of load data with regard to potential lumbar overloading during single operations, working shifts and the entire occupational life. Thenew recommendations on maximum daily exposure for lifelong work for both men and women are bridging the former gap of biomechanically justified action frequency limits and now offer the possibility of a completely biomechanical path for risk assessment of manual materials handling. The book provides hence a serious contribution to the objectification of lumbar load and load-bearing capacity aiming at an ergonomic work design of manual materials handling for short- as well as long-term exposures.
