Fluid mechanical aspects of separated and vortical flow in aircraft wing aerodynamics are treated. The focus is on two wing classes: (1) large aspect-ratio wings and (2) small aspect-ratio delta-type wings. Aerodynamic design issues in general are not dealt with.Discrete numerical simulation methods play a progressively larger role in aircraft design and development. Accordingly, in the introduction to the book the different mathematical models are considered, which underlie the aerodynamic computation methods (panel methods, RANS and scale-resolving methods). Special methods are the Euler methods, which as rather inexpensive methods embrace compressibility effects and also permit to describe lifting-wing flow.The concept of the kinematically active and inactive vorticity content of shear layers gives insight into many flow phenomena, but also, with the second break of symmetry---the first one is due to the Kutta condition---an explanation of lifting-wing flow fields. The prerequisite is an extended definition of separation: ¿flow-off separation¿ at sharp trailing edges of class (1) wings and at sharp leading edges of class (2) wings. The vorticity-content concept, with a compatibility condition for flow-off separation at sharp edges, permits to understand the properties of the evolving trailing vortex layer and the resulting pair of trailing vortices of class (1) wings. The concept also shows that Euler methods at sharp delta or strake leading edges of class (2) wings can give reliable results.Three main topics are treated:1) Basic Principles are considered first: boundary-layer flow, vortex theory, the vorticity content of shear layers, Euler solutions for lifting wings, the Kutta condition in reality and the topology of skin-friction and velocity fields.2) Unit Problems treat isolated flow phenomena of the two wing classes. Capabilities of panel and Euler methods are investigated. One Unit Problem is the flow past the wing of the NASA Common Research Model. Other Unit Problems concern the lee-side vortex system appearing at the Vortex-Flow Experiment 1 and 2 sharp- and blunt-edged delta configurations, at a delta wing with partly round leading edges, and also at the Blunt Delta Wing at hypersonic speed.3) Selected Flow Problems of the two wing classes. In short sections practical design problems are discussed. The treatment of flow past fuselages, although desirable, was not possible in the frame of this book.
This book provides insights into the inspiring and multifaceted field of advertising research, which is confronted with challenges regarding ad content and execution, media placement, as well as online and social media. Distinguishing between digital, classic, subtle and alternative advertising formats, renowned scholars from around the globe contribute state-of the-art research on these issues in 23 chapters. Advances in Advertising Research are published by European Advertising Academy (EAA). This volume is a compilation of research presented at the 18th International Conference in Advertising (ICORIA), which was held in Krems (Austria) in June 2019. The conference gathered around 150 participants from all over the world.¿
This book summarizes the concrete, practical issues surrounding Ménière¿s disease with vertigo, hearing loss, tinnitus, and offers perspectives and recommendations for affected persons, relatives, and medical and psychotherapeutic practitioners. In the course of Ménière¿s disease, in addition to the organic impairment anxious observation with increasing restriction of movement space, insecurity and helplessness, and even occupational disability and depressive development may occur. Nevertheless, help and support are possible, how is shown in this first English edition, which was translated from the updated 8th German edition with the help of "Artificial Intelligence" (DeepL). Even though this was subsequently carefully proofread and adjusted by the author, it may be that much of it sounds "bumpy" - perhaps as is fitting for the disorder, certainly as is fitting for the fact that the author is not a native speaker of English. Nevertheless, the facts are described accurately.From the contentsInformation on current findings in dealing with Ménière¿s disease ¿ Improved medical options and limitations ¿ Refined psychosomatic approaches to dealing with the disease.This book is a translation of the original German 1st edition Morbus Menière by Helmut Schaaf published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2017.The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
The new edition of this well received primer on rigorous aspects of symmetry breaking presents a more detailed and thorough discussion of the mechanism of symmetry breaking in classical field theory in relation with the Noether theorem.

During the last decades, a considerable amount of research has been directed towards explaining the concept of Digital Human Resource Management (DHRM). Yet, a holistic assessment of DHRM antecedents and consequences with respect to possible contextual contingencies is still missing. To this end, this thesis introduces a research framework illuminating the multifaceted phenomenon of DHRM from various perspectives. An exploratory four-step meta-analytic structural equation modelling (E-MASEM) approach tailored to address the domain-specific challenges of DHRM is introduced and applied. Results identify 32 constructs associated with the DHRM usage phenomenon which are categorized into DHRM antecedents and DHRM consequences. Findings reveal that user perceptions, expectations, attitudes, and intentions are essential in predicting DHRM usage while HRM service quality and user satisfaction are found crucial in explaining other DHRM consequences. Further, practitioners are informed about therelative importance of factors for both facilitating DHRM adoption and measuring DHRM success. Lastly, this thesis also contributes to the MASEM methodology by outlining a new approach to summarize statistical inferences from multiple moderator tests.
The success of a digital transformation is not a foregone conclusion. A digital transformation, as a highly complex process impacting major areas of an organization, requires a systematic approach that goes beyond individual transformation initiatives. This work analyses and integrates existing approaches to managing and coordinating a digital transformation in order to identify relevant success factors of a digital transformation, serving as a basis for the development of a systematic framework for a management model of digital transformation. The analysis reveals ten success-critical focus areas of a digital transformation, which comprise numerous success factors: ¿Vision, goals, and strategies¿, ¿Leadership¿, ¿Communication¿, ¿Digital culture and mindset¿, ¿Digital platform¿, ¿Partnership network¿, ¿Capabilities, talents, and skills¿, ¿Organization, coordination, and roles¿, ¿Management methodologies¿, and ¿Governance¿. A systematic framework is proposed that serves as a foundationfor the future development of a management model, addressed to executives and experts who are tasked with launching, driving, and sustaining a digital transformation.
