Anwendungen und Fehlerquellen der digitalen Messverfahren werden an Beispielen diskutiert.

Success in scientific and engineering research depends on effective writing and presentation. The purpose of this guide is to help the reader achieve that goal. It enables students and researchers to write and present material to a professional modern standard, efficiently and painlessly, and with maximum impact. The approach is not prescriptive. Rather, the emphasis is on a logical approach to communication, informed by what needs to be achieved, what works in practice, and what interferes with success. Over 400 examples of good and bad writing and graphing are presented. Each is from a published research article and is accompanied by analysis, comment, and correction where needed. Journal reviewers' critiques of submitted manuscripts are included to illustrate common pitfalls. Above all, this is a "how-to" book, comprehensive but concise, suitable for continuous study or quick reference. Checklists at the end of each chapter enable the reader to test the readiness of a dissertation, journal submission, or conference presentation for assessment or review. Although oriented towards engineering and the physical and life sciences, it is also relevant to other areas, including behavioural and clinical sciences and medicine.

A scientist is always led by intellectual curiosity; obviously he has collected information about the subjects of the field of interest in a systematic way (this attitude was moved by a peculiar interest that lets him investigate on all aspects of the problem, also dwelling upon aspects apparently marginal or non-traditional (this habit was not taught to him by anyone). In this case he already shows the so called "scheme-breaking" attitude rather than an attitude that would imply a systematic and essential examination of the state of art. This book addresses the scientific investigation carried out with the greatest originality driven by that intellectual curiosity but it must face the experimental evidence to get irrefutable results.

Inhalte richten sich Praktiker und Studierende Von den Inhalten dieses Buchs uber die Schaltungstechnik profitieren sowohl Studenten als auch Ingenieure. Samtliche Kapitel wurden entsprechend der neuesten technischen Entwicklungen uberarbeitet. Es vermittelt Grundlagenwissen aber auch tiefergehende Informationen.

This book brings together two broad themes that have generated a great deal of interest and excitement in the scientific and technical community in the last 100 years or so: quantum tunnelling and nonlinear dynamical systems. It applies these themes to nanostructured solid state heterostructures operating at room temperature to gain insight into novel photonic devices, systems and applications.

The fascinating stories behind the essential seven units of measurement that allow us to understand the physical world   “Entertaining popular science and a literate tale of why things are as they are.�—Kirkus Reviews   From the beginning of history, measurement has been interwoven into the human experience, shaping our understanding of nature, personal relationships, and the supernatural. We measure the world to know our past, comprehend the present, and plan the future.   Renowned physicist Piero Martin explores how scientific knowledge is built around seven key pillars of measurement: the meter for length; the second for time; the kilogram for mass; the kelvin for temperature; the ampere for electricity; the mole for quantity of substance; and the candela for luminous intensity. Martin examines the history and function of these units and illustrates their applications in rich vignettes on a range of topics—from quarks to black holes, from a glass of wine to space exploration. He delves into not only the all-important numbers but also anecdotes that underline each unit’s special quality. At the same time, he explains how each unit contributes to important aspects of science, from classical physics to quantum mechanics, from relativity to chemistry, from cosmology to elementary particle physics, and from medicine to modern technology. Martin eloquently shows how the entire universe can be measured and understood using just seven units.

Written by three leading experts in the field, this textbook describes and explains all aspects of the scanning probe microscopy. Emphasis is placed on the experimental design and procedures required to optimize the performance of the various methods. Scanning Probe Microscopy covers not only the physical principles behind scanning probe microscopy but also questions of instrumental designs, basic features of the different imaging modes, and recurring artifacts. The intention is to provide a general textbook for all types of classes that address scanning probe microscopy. Third year undergraduates and beyond should be able to use it for self-study or as textbook to accompany a course on probe microscopy. Furthermore, it will be valuable as reference book in any scanning probe microscopy laboratory. Novel applications and the latest important results are also presented, and the book closes with a look at the future prospects of scanning probe microscopy, also discussing related techniques in nanoscience. Ideally suited as an introduction for graduate students, the book will also serve as a valuable reference for practising researchers developing and using scanning probe techniques.

For a physicist, "noise" is not just about sounds, but refers to any random physical process that blurs measurements, and in so doing stands in the way of scientific knowledge. This book deals with the most common types of noise, their properties, and some of their unexpected virtues. The text explains the most useful mathematical concepts related to noise. Finally, the book aims at making this subject more widely known and to stimulate the interest for its study in young physicists.

A single-source reference with a broad and holistic overview of nonclinical studies, this book offers critical training material and describes regulations of nonclinical testing through guidelines, models, case studies, practical examples, and worldwide perspectives. The book: * Provides a complete overview of nonclinical study organization, conduct, and reporting and describes the roles and responsibilities of a Study Director to manage an effective study * Covers regulatory and scientific concepts, including international testing and Good Laboratory Practice (GLP), compliance with guidelines, and animal models * Features a concluding chapter that compiles case studies / lessons learned from those that have served as a Study Director for many years * Addresses the entire spectrum of nonclinical testing, making it applicable to those in the government, laboratories and those actively involved in in all sectors of industry

Real science is dead. Researchers are no longer trying to seek and speak the truth. Scientists no longer believe in the truth. They no longer believe that there is an eternal unchanging reality beyond our human organisation which they have a duty to discover and disseminate. Hence, the vast structures of personnel and resources that constitute modern science are not real science but merely a professional research bureaucracy. The consequences? Research literature must be assumed to be worthless or misleading and should almost always be ignored. In practice, this means that nearly all science needs to be demolished (or allowed to collapse) and real science rebuilt outside the professional research structure, from the ground up, by real scientists who regard truth-seeking as an imperative and truthfulness as an iron law.
