This book was released on 2013-12-01 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1980s and 1990s have seen a growing interest in research and practice in the use of methodologies within problem contexts characterised by a primary focus on technology, human issues, or power. During the last five to ten years, this has given rise to challenges regarding the ability of a single methodology to address all such contexts, and the consequent development of approaches which aim to mix methodologies within a single problem situation. This has been particularly so where the situation has called for a mix of technological (the so-called 'hard') and human centred (so-called 'soft') methods. The approach developed has been termed mixed-mode modelling. The area of mixed-mode modelling is relatively new, with the phrase being coined approximately four years ago by Brian Lehaney in a keynote paper published at the 1996 Annual Conference of the UK Operational Research Society. Mixed-mode modelling, as suggested above, is a new way of considering problem situations faced by organisations. Traditional technological approaches used in management science have suffered criticisms relating to their adequacy in the past few decades, and these hard approaches have been replaced by soft methods, which consider process more relevant than outcome. However, the sole use of human centred approaches to organisational problems has also proved to be inadequate. Mixed-mode modelling accepts the importance of both process and outcome, and provides enabling mechanisms for hard and soft investigation to be undertaken.

Available in PDF, EPUB and Kindle. Book excerpt: Mixed-mode surveys have become a standard at many statistical institutes. However, the introduction of multiple modes in one design goes with challenges to both methodology and logistics. Mode-specific representation and measurement differences become explicit and demand for solutions in data collection design, questionnaire design, and estimation. This is especially true when surveys are repeated and are input to long time series of official statistics. So how can statistical institutes deal with such changes? What are the origins of mode-specific error? And how can they be dealt with? In this book, the authors provide answers to these questions, and much more. Features Concise introduction to all the key elements of mixed-mode survey design and analysis Realistic official statistics examples from three general population surveys Suitable for survey managers and survey statisticians alike An overview of mode-specific representation and measurement errors and how to avoid, reduce and adjust them

Download or read book Fitness for Service Fracture Assessment of Structures Containing Cracks written by Uwe Zerbst and published by Academic Press. This book was released on 2013-10-22 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Fitness-for-Service Fracture Assessment of Structures Containing Cracks is to facilitate the use of fracture mechanics based failure assessment procedures for the evaluation and design of structures and components. All practical structures contain flaws and the optimum combination of cost efficiency and safety whilst achieving the required capability, can only be realised by using state of the art methods such as that represented by the European flaw assessment method SINTAP/FITNET to analyse the safety risk. This book is written by practitioners with extensive experience in both the development and use of integrity assessment methods and provides comprehensive information on the basic principles and use of analytical flaw assessment. It provides an introduction to the method, its background, how it can be applied, its potential and, importantly, its limitations. The explanations are complimented by using a large number of worked examples and validation exercises which illustrate all aspects of the procedure. In addition, for students and engineers who are new to the subject, a comprehensive glossary of basic terms used in fracture mechanics based integrity evaluations is included. The topics addressed include: - Crack driving force (CDF) and failure assessment diagram (FAD) type analyses - Preparation of the input parameters (crack dimensions, stress-strain properties, fracture toughness, statistical aspects) - Determination of the model parameters, (stress intensity factor and yield load solutions) - Treatment of combined primary and secondary loading, together with residual stress effects - Analysis of the effect of constraint effects (treatment of small defects and section size effects) - Treatment of mixed mode loading - Consideration of the influences of strength mismatch - Reliability aspects - Comprehensive description of the use of structural integrity methods to optimise cost effectiveness and safety - Detailed description of how to evaluate the integrity of structures containing cracks - Valuable background information for understanding the methods, their potential and limitations - Large number of worked examples, which demonstrate all aspects of the methods - Descriptive, readable writing style - Applicable to a wide range of interests, from the student (university or self study) to the expert who requires a 'state of the art' document

Download or read book Handbook of Structural Life Assessment written by Raouf A. Ibrahim and published by John Wiley & Sons. This book was released on 2017-03-29 with total page 1421 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important, self-contained reference deals with structural life assessment (SLA) and structural health monitoring (SHM) in a combined form. SLA periodically evaluates the state and condition of a structural system and provides recommendations for possible maintenance actions or the end of structural service life. It is a diversified field and relies on the theories of fracture mechanics, fatigue damage process, and reliability theory. For common structures, their life assessment is not only governed by the theory of fracture mechanics and fatigue damage process, but by other factors such as corrosion, grounding, and sudden collision. On the other hand, SHM deals with the detection, prediction, and location of crack development online. Both SLA and SHM are combined in a unified and coherent treatment.
