DOWNLOAD EBOOKThe book has evolved from the author's continuing teaching of the subject and from two editions of a text of the same title. The first edition was published in 1978 by the School of Surveying, Universi ty of New South Wales, Sydney, Australia. Like its predecessors, this totally revised third edition is designed to make the subject matter more readily available to students proceeding to degrees in Survey ing and related fields. At the same time, it is a comprehensive refer ence book for all surveyors as well as for other professionals and scientists who use electronic distance measurement as a measuring tool. Great emphasis is placed on the understanding of measure ment principles and on proper reduction and calibration pro cedures. It comprises an extensive collection of essential formulae, useful tables and numerous literature references. After a review of the history of EDM instruments in Chapter 1, some fundamental laws of physics and units relevant to EDM are revised in Chapter 2. Chapter 3 discusses the principles and applica tions of the pulse method, the phase difference method, the Doppler technique and includes an expanded section on interferometers. The basic working principles of electro-optical and microwave distance meters are presented in Chapter 4, with special emphasis on modu lation/demodulation techniques and phase measurement systems. Important properties of infrared emitting and lasing diodes are discussed.

DOWNLOAD EBOOKAs more postsecondary faculty become engaged in designing online learning environments, research conducted on distance education program quality becomes increasingly important. Measurements in Distance Education is a concise, well-organized guide to some of the many instruments, scales, and methods that have been created to assess distance education environments, learners, and teachers. Entries are organized according to the qualities these measures attempt to gauge—such as engagement and information retention—and provide summaries of each instrument, usage information, the history of its development, and validation, including any reported psychometric properties. Offering more than 50 different surveys, tests, and other metrics, this book is an essential reference for anyone interested in understanding distance education assessment.

DOWNLOAD EBOOKDistance determination is an essential technique in astronomy, and is briefly covered in most textbooks on astrophysics and cosmology. It is rarely covered as a coherent topic in its own right. When it is discussed the approach is frequently very dry, splitting the teaching into, for example, stars, galaxies and cosmologies, and as a consequence, books lack depth and are rarely comprehensive. Adopting a unique and engaging approach to the subject An Introduction to distance Measurement in Astronomy will take the reader on a journey from the solar neighbourhood to the edge of the Universe, discussing the range of distance measurements methods on the way. The book will focus on the physical processes discussing properties that underlie each method, rather than just presenting a collection of techniques. As well as providing the most compressive account of distance measurements to date, the book will use the common theme of distance measurement to impart basic concepts relevant to a wide variety of areas in astronomy/astrophysics. The book will provide an updated account of the progress made in a large number of subfields in astrophysics, leading to improved distance estimates particularly focusing on the underlying physics. Additionally it will illustrate the pitfalls in these areas and discuss the impact of the remaining uncertainties in the complete understanding of the Universes at large. As a result the book will not only provide a comprehensive study of distance measurement, but also include many recent advances in astrophysics.

DOWNLOAD EBOOKEverything is getting more complex. It is easy to be overwhelmed by the amount of information we encounter each day. Whether at work, at school, or in our personal endeavors, there's a deepening (and inescapable) need for people to work with and understand information. Information architecture is the way that we arrange the parts of something to make it understandable as a whole. When we make things for others to use, the architecture of information that we choose greatly affects our ability to deliver our intended message to our users.We all face messes made of information and people. This book defines the word "mess" the same way that most dictionaries do: "A situation where the interactions between people and information are confusing or full of difficulties." - Who doesn't bump up against messes made of information and people every day? How to Make Sense of Any Mess provides a seven step process for making sense of any mess. Each chapter contains a set of lessons as well as workbook exercises architected to help you to work through your own mess.

DOWNLOAD EBOOKHow do astronomers know what they know about the stars and planets? That is the question behind today's rapid pace of cosmic discovery, for every new finding rests upon a centuries-long foundation of astronomical practice. Introduction to Stars and Planets: An activities-based exploration reveals the methods by which Earthbound observers have deduced the physical attributes of celestial bodies, whether situated within our solar neighborhood or at the far ends of the galaxy. The book's 28 mildly mathematical activities invite readers to carry out the essential work of the astronomer by utilizing real observational data sets and high-quality celestial photographs to establish the innate properties of a range of cosmic systems. Taken in sequence, these activities illustrate the epic advancement of stellar and planetary astronomy over the past century, up to the present day. Key Features Wide-ranging topical coverage of both historical and up-to-the-minute aspects of astronomical discovery Uses a learning-by-doing approach Structured, goal-oriented framework centered on the methods and physical principles by which astronomers study the universe Provides real-time educational feedback to students Introduces elementary mathematics for students to gain a truer sense of the work astronomers do

DOWNLOAD EBOOKAn interdisciplinary history of standardized measurements. Measurement is all around us—from the circumference of a pizza to the square footage of an apartment, from the length of a newborn baby to the number of miles between neighboring towns. Whether inches or miles, centimeters or kilometers, measures of distance stand at the very foundation of everything we do, so much so that we take them for granted. Yet, this has not always been the case. This book reaches back to medieval Italy to speak of a time when measurements were displayed in the open, showing how such a deceptively simple innovation triggered a chain of cultural transformations whose consequences are visible today on a global scale. Drawing from literary works and frescoes, architectural surveys, and legal compilations, Emanuele Lugli offers a history of material practices widely overlooked by historians. He argues that the public display of measurements in Italy’s newly formed city republics not only laid the foundation for now centuries-old practices of making, but also helped to legitimize local governments and shore up church power, buttressing fantasies of exactitude and certainty that linger to this day. This ambitious, truly interdisciplinary book explains how measurements, rather than being mere descriptors of the real, themselves work as powerful molds of ideas, affecting our notions of what we consider similar, accurate, and truthful.
