简介:In its most general context, the term a'materials measurementsa? denotes operations to distinguish qualitatively and to determine quantitatively characteristics of materials. As materials constitute the physical matter of all products a? machines, devices, plants, commodities, means of information, communication, transport, habitation and energy supply a? materials measurements have a wide scope and impact for science and technology, economy and society. This Handbook compiles advanced methods for materials measurement and characterization from the macroscopic to the nano-scale. Materials science and its industrial applications require the highest level of accuracy and reliability in the measurement of the properties of materials and the assessment of their safety and reliability. Indeed, major technological nations fund large laboratories for testing and measurements that set standards, assess the safety and reliability of materials, and oversee the use of dangerous materials. But behind and beyond the data themselves are the underlying methods whose sophistication and proper use are absolutely necessary to achieve the accuracy, reliability, and safety required by modern technologies. In addition, the acceleration of the design and creation of new materials via techniques such as molecular modeling and simulation, especially on the nanoscale, makes the measurement of new materials properties and their characterization ever more critical. So materials professionals need not only handbooks of materials data but clear guidelines and standards for how to measure the full spectrum of materials characteristics of new materials ans systems. Since materials science forms a bridge between the more traditonal fields of physics, engineering, and chemistry, unifying the varying perspectives and covering the full gamut of properties also serves a useful purpose. This handbook is the first dedicated to these practical and important considerations.

简介:Summary: Publisher Summary 1 Credit risk evaluation is as old as commerce itself.聽 Processes have been refined over centuries based on cumulative experience, judgment and learning.聽 The rapid development of financial markets however has tested the limits of the traditional approach as highly publicized credit losses and huge non-performing loans across the globe well document.聽 Distress among many credit professionals and regulators prevails.聽 This book describes a different and unemotional approach to credit risk evaluation.聽 Based on abstract and objective credit models, the concept of credit risk measurement is introduced through a range of theoretical and practical perspectives.From making a case for credit risk measurement as a complement to the more traditional approaches to credit risk management, the book covers validation, applications and new areas of credit risk management.聽 Contributions by leading academics, practitioners and consultants provide for scholars and credit risk professionals but also less mathematically inclined readers or interested parties, a wide spectrum of ideas and concepts for developing and improving their own viewpoint, processes and approaches.聽 A demo-CD of one particular model is included for practical testing and playing with applied credit risk measurement concepts.
