The subject of this book is estimating parameters of expectation models of statistical observations. The book describes the most important aspects of the subject for applied scientists and engineers. This group of users is often not aware of estimators other than least squares. Therefore one purpose of this book is to show that statistical parameter estimation has much more to offer than least squares estimation alone. In the approach of this book, knowledge of the distribution of the observations is involved in the choice of estimators. A further advantage of the chosen approach is that it unifies the underlying theory and reduces it to a relatively small collection of coherent, generally applicable principles and notions.
Advanced Manufacturing Technology for Medical Applications
Advanced manufacturing technologies (AMTs) combine novel manufacturing techniques and machines with the application of information technology, microelectronics and new organizational practices within the manufacturing sector. They include «hard» technologies such as rapid prototyping, and «soft» technologies such as scanned point cloud data manipulation. AMTs contribute significantly to medical and biomedical engineering. The number of applications is rapidly increasing, with many important new products now under development. Advanced Manufacturing Technology for Medical Applications outlines the state of the art in advanced manufacturing technology and points to the future development of this exciting field. Early chapters look at actual medical applications already employing AMT, and progress to how reverse engineering allows users to create system solutions to medical problems. The authors also investigate how hard and soft systems are used to create these solutions ready for building. Applications follow where models are created using a variety of different techniques to suit different medical problems One of the first texts to be dedicated to the use of rapid prototyping, reverse engineering and associated software for medical applications Ties together the two distinct disciplines of engineering and medicine Features contributions from experts who are recognised pioneers in the use of these technologies for medical applications Includes work carried out in both a research and a commercial capacity, with representatives from 3 companies that are established as world leaders in the field – Medical Modelling, Materialise, & Anatomics Covers a comprehensive range of medical applications, from dentistry and surgery to neurosurgery and prosthetic design Medical practitioners interested in implementing new advanced methods will find Advanced Manufacturing Technology for Medical Applications invaluable as will engineers developing applications for the medical industry. Academics and researchers also now have a vital resource at their disposal.
Multidisciplinary Design Optimization in Computational Mechanics
This book provides a comprehensive introduction to the mathematical and algorithmic methods for the Multidisciplinary Design Optimization (MDO) of complex mechanical systems such as aircraft or car engines. We have focused on the presentation of strategies efficiently and economically managing the different levels of complexity in coupled disciplines (e.g. structure, fluid, thermal, acoustics, etc.), ranging from Reduced Order Models (ROM) to full-scale Finite Element (FE) or Finite Volume (FV) simulations. Particular focus is given to the uncertainty quantification and its impact on the robustness of the optimal designs. A large collection of examples from academia, software editing and industry should also help the reader to develop a practical insight on MDO methods.
Building Physics -- Heat, Air and Moisture
Bad experiences with construction quality, the energy crises of 1973 and 1979, complaints about 'sick buildings', thermal, acoustical, visual and olfactory discomfort, the move towards more sustainability, have all accelerated the development of a field, which until 35 years ago was hardly more than an academic exercise: building physics. Through the application of existing physical knowledge and the combination with information coming from other disciplines, the field helps to understand the physical performance of building parts, buildings and the built environment, and translates it into correct design and construction. This book is the result of thirty years teaching, research and consultancy activity of the author. The book discusses the theory behind the heat and mass transport in and through building components. Steady and non steady state heat conduction, heat convection and thermal radiation are discussed in depth, followed by typical building-related thermal concepts such as reference temperatures, surface film coefficients, the thermal transmissivity, the solar transmissivity, thermal bridging and the periodic thermal properties. Water vapour and water vapour flow and moisture flow in and through building materials and building components is analyzed in depth, mixed up with several engineering concepts which allow a first order analysis of phenomena such as the vapour balance, the mold, mildew and dust mites risk, surface condensation, sorption, capillary suction, rain absorption and drying. In a last section, heat and mass transfer are combined into one overall model staying closest to the real hygrothermal response of building components, as observed in field experiments. The book combines the theory of heat and mass transfer with typical building engineering applications. The line from theory to application is dressed in a correct and clear way. In the theory, oversimplification is avoided. This book is the result of thirty years teaching, research and consultancy activity of the author.
Strategic Issues in Public-Private Partnerships
The book provides an international overview of developments in public-private partnerships (PPP) in different countries, and addresses the various characteristics and approaches to PPP. Drawing on a number of international studies carried out by the authors, the book describes the rationale behind various PPP approaches, looks at the process aspects and dynamics of PPPs and aims to stimulate a more strategic discussion of PPP.
Human Performance and Limitations in Aviation
Human error is cited as a major cause in over 70% of accidents, and it is widely agreed that a better understanding of human capabilities and limitations – both physical and psychological – would help reduce human error and improve flight safety. This book was first published when the UK Civil Aviation Authority introduced an examination in human performance and limitations for all private and professional pilot licences. Now the Joint Aviation Authorities of Europe have published a new syllabus as part of their Joint Aviation Requirements for Flight Crew Licensing. The book has been completely revised and rewritten to take account of the new syllabus. The coverage of basic aviation psychology has been greatly expanded, and the section on aviation physiology now includes topics on the high altitude environment and on health maintenance. Throughout, the text avoids excessive jargon and technical language. «There is no doubt that this book provides an excellent basic understanding of the human body, its limitations, the psychological processes and how they interact with the aviation environment. I am currently studying for my ATPL Ground Exams and I found this book to be an invaluable aid. It is equally useful for those studying for the PPL and for all pilots who would like to be reminded of their physiological and psychological limitations.» –General Aviation, June 2002
Boundary Value Problems for Transonic Flow
Transonic flow occurs around moving objects as they approach and cross the sound barrier. Serious problems can occur at this point, such as shock-induced flow separation which can cause the aircraft to spin out of control. Another important practical problem is the achievement of higher aerodynamic performance of aircraft at cruise conditions, which leads to considerable fuel savings. The success in application of numerical methods for simulation of transonic flow and aircraft design depends on developments in the underlying mathematical theory. This book presents a breakthrough in the solvability analysis of boundary value problems, which makes it possible to establish convergence of finite element approximations for shock-free flow and to provide a framework for putting the existing numerical methods on a more sound basis. Also, physical aspects concerned with patterns of formation and propagation of weak shock waves are analysed. This contributes to the understanding of the extreme sensitivity of transonic flow to perturbation of freestream conditions. The developed theoretical knowledge base yields promising concepts of the airfoil design and active flow control by airfoil/wing shape modifications or suction/blowing through a perforated surface. Boundary Value Problems for Transonic Flow * Focuses on Computational Fluid Dynamics. * Addresses practical problems, such as airfoil design and flow control. * Presents developments made in the last two decades. In essence this is a much needed monograph for researchers and engineers in applied mathematics and numerical analysis applied to aerodynamics and for algorithm developers in Computational Fluid Dynamics in the aircraft industry. It gives design engineers the underlying mathematical theory necessary for developing new concepts for airfoil/wing design and flow control.
Mechanical Characterization of Materials and Wave Dispersion
Dynamic tests have proven to be as efficient as static tests and are often easier to use at lower frequency. Over the last 50 years, the methods of investigating dynamic properties have resulted in significant advances. This book explores dynamic testing, the methods used, and the experiments performed, placing a particular emphasis on the context of bounded medium elastodynamics. The discussion is divided into four parts. Part A focuses on the complements of continuum mechanics. Part B concerns the various types of rod vibrations: extensional, bending, and torsional. Part C is devoted to mechanical and electronic instrumentation, and guidelines for which experimental set-up should be used are given. Part D concentrates on experiments and experimental interpretations of elastic or viscolelastic moduli. In addition, several chapters contain practical examples alongside theoretical discussion to facilitate the reader?s understanding. The results presented are the culmination of over 30 years of research by the authors and as such will be of great interest to anyone involved in this field.
Beispiele zur Bemessung nach Eurocode 2, Band 2
Deutscher Beton- und Bautechnik-Verein e.V.
Der Eurocode 2 – DIN EN 1992 „Bemessung und Konstruktion von Stahlbeton- und Spannbetontragwerken“ mit seinen Nationalen Anhängen wurde im Jahr 2012 bauaufsichtlich eingeführt. Seit 2013 sind die Eurocodes auch für den Brücken- und Ingenieurbau der Bundesfernstraßen und der Eisenbahnen des Bundes verbindlich anzuwenden. Für das Verständnis und die Einarbeitung in den Eurocode 2 legt der Deutsche Beton- und Bautechnik-Verein E. V. eine aktualisierte Beispielsammlung vor. Band 2 enthält acht durchgerechnete Beispiele für typische Bauteile des Brücken-, Ingenieur- und Hochbaus. Diese entsprechen den aus der DBV-Beispielsammlung zu DIN 1045-1 bekannten Beispielen und gestatten somit einen direkten Vergleich der Bemessungsregeln und der Ergebnisse nach beiden Normen. Die Aufgabenstellungen sind komplexer als im ersten Band gefasst (Spannbeton-Straßenbrücken, Vorspannung von Flachdecken, Gebäudeaussteifung) bzw. auf spezielle Nachweise (plastische und nichtlineare Berechnungsverfahren, Durchbiegung, Erdbebenbemessung) ausgerichtet. Die Autoren haben versucht, die wesentlichen Neuerungen und einige noch nicht im Band 1 gezeigte Nachweise nach Eurocode 2 in einer verständnisfördernden Ausführlichkeit darzustellen und auch, wo notwendig, die Hintergründe computergestützt erzielter Ergebnisse zu erläutern. Die Sammlung vermittelt Praktikern und Studenten fundierte Kenntnisse der Nachweisführung nach Eurocode 2 und dient als Hilfsmittel bei der Erstellung prüffähiger statischer Berechnungen im Stahlbeton- und Spannbetonbau. Beispiele: • Plattenbalkenbrücke • Fertigteilbrücke • Müllbunkerwand • Deckenplatte nach Bruchlinientheorie • Flachdecke mit Vorspannung ohne Verbund • Flachdecke mit Kragarm • Nichtlineare Berechnung gekoppelter Stützen • Mehrgeschossiger Skelettbau – Erdbeben
fib Model Code for Concrete Structures 2010
fib – fédération internationale du béton
The International Federation for Structural Concrete (fib) is a pre-normative organization. 'Pre-normative' implies pioneering work in codification. This work has now been realized with the fib Model Code 2010. The objectives of the fib Model Code 2010 are to serve as a basis for future codes for concrete structures, and present new developments with regard to concrete structures, structural materials and new ideas in order to achieve optimum behaviour. The fib Model Code 2010 is now the most comprehensive code on concrete structures, including their complete life cycle: conceptual design, dimensioning, construction, conservation and dismantlement. It is expected to become an important document for both national and international code committees, practitioners and researchers. The fib Model Code 2010 was produced during the last ten years through an exceptional effort by Joost Walraven (Convener; Delft University of Technology, The Netherlands), Agnieszka Bigaj-van Vliet (Technical Secretary; TNO Built Environment and Geosciences, The Netherlands) as well as experts out of 44 countries from five continents.
