Outdoor Lighting Physics Vision And Perception

The present book is based on the experience of the author. The experience is mainly the result of years of research, of consulting work, and in participation in policy decision making in many felds, most, but not all, related to outdoor lighting. To some degree, the book represents the preference of the author. The selection of the subjects is based on more than 50 years of experience of what is desirable to know for persons engaged in scientifc research or practical application in the felds of lighting and vision. The subjects deal with a number of fundamental aspects. The theorists must have them at their fngertips, whereas the practical engineers may assume them as known in their daily work. The selection of subjects is based in part by the questions that came to the author over the years, but even more by the preference of the author himself. In this respect, it is a personal book. Thus, it should be stressed that the book is not a ‘handbook’ or even a ‘textbook’; many subjects that commonly are treated in such books are not included here. Not because they lack importance, but because the author feels that they are adequately treated elsewhere. Some relevant works are mentioned in the References. Over the years, the author has been engaged in giving courses on vision and lighting, lately more in particular on Masterclasses on a post-graduate or post-doctorate level.

Vision is about insight, and visual perception is about cognition - and they form the foundation of how we see the world. Duco A. Schreuder, a physicist and psychologist, explores the finer details of each in this groundbreaking book that explores human consciousness and perception. Sharing virtually everything he's learned over a varied career spanning more than sixty years, he examines a wide array of topics, including how we understand what we visually process, how we store and retrieve information, the role that neurons play in how what we see, and much more. While Schreuder isn't afraid to disagree with other leading thinkers, he relies on science and focuses on the facts behind it so you can understand lighting, visual perception, engineering design, and applied and experimental physics. Looking is about insight, whereas seeing is about knowledge, and you need to know how each one works to truly understand how humanity views the world. Whether you're an illuminating engineer considering the fundamentals of the trade or a student or professional in an allied discipline, you'll be well served by taking a closer look at Vision and Visual Perception.

Visible Light Communications, written by leading researchers, provides a comprehensive overview of theory, stimulation, design, implementation, and applications. The book is divided into two parts – the first devoted to the underlying theoretical concepts of the VLC and the second part covers VLC applications. Visible Light Communications is an emerging topic with multiple functionalities including data communication, indoor localization, 5G wireless communication networks, security, and small cell optimization. This concise book will be of valuable interest from beginners to researchers in the field.

This book deals with human factors research directed towards realizing and assessing sustainability in the built environment. It reports on advanced engineering methods for sustainable infrastructure design, as well as on assessments of the efficient methods and the social, environmental, and economic impact of various designs and projects. The book covers a range of topics, including the use of recycled materials in architecture, ergonomics in buildings and public design, sustainable design for smart cities, design for the aging population, industrial design, human scale in architecture, and many more. Based on the AHFE 2017 International Conference on Human Factors, Sustainable Urban Planning and Infrastructure, held on July 17–21, 2017, in Los Angeles, California, USA, this book, by showing different perspectives on sustainability and ergonomics, represents a useful source of information for designers in general, urban engineers, architects, infrastructure professionals, practitioners, public infrastructure owners, policy makers, government engineers and planners, as well as operations managers, and academics active in applied research.

This volume is designed to impart the fundamental concepts in experimental pharmacology, research methodology and biostatistics. Through this book, the readers will learn about different methods involved in drug discovery, experimental animals and their care, equipments and the various bioassays used in experimental pharmacology. This book contains special sections on various drug screening methods involved in the evaluation of different body systems. Certain sections provide the healthcare professionals with the knowledge necessary to interpret clinical research articles, design clinical studies, and learn essential concepts in biostatistics in an expedient and concise manner. Basic principles and applications of simple analytical methods employed in drug analysis are well written under one section. It focuses on the basic and advanced laboratory techniques and also on computer simulated data, written extensively under the Biostatistics section. The methods used for drug analysis have been described in adequate detail with cross-references for further studies and comprehension. Overall, the book is designed systematically with four broad sections with extensive subdivisions for easy tracking, interpretation, and understanding.

Promoting the design, application and evaluation of visually and electrically effective LED light sources and luminaires for general indoor lighting as well as outdoor and vehicle lighting, this book combines the knowledge of LED lighting technology with human perceptual aspects for lighting scientists and engineers. After an introduction to the human visual system and current radiometry, photometry and color science, the basics of LED chip and phosphor technology are described followed by specific issues of LED radiometry and the optical, thermal and electric modeling of LEDs. This is supplemented by the relevant practical issues of pulsed LEDs, remote phosphor LEDs and the aging of LED light sources. Relevant human visual aspects closely related to LED technology are described in detail for the photopic and the mesopic range of vision, including color rendering, binning, whiteness, Circadian issues, as well as flicker perception, brightness, visual performance, conspicuity and disability glare. The topic of LED luminaires is discussed in a separate chapter, including retrofit LED lamps, LED-based road and street luminaires and LED luminaires for museum and school lighting. Specific sections are devoted to the modularity of LED luminaires, their aging and the planning and evaluation methods of new LED installations. The whole is rounded off by a summary and a look towards future developments.

This book explores new criteria and characteristics for integrating human psychology in the design of modern urban lighting. It identifies a new area of lighting design research and practice that focuses on the nocturnal urban experience in terms of people’s emotional, cognitive and motivational perceptions to achieve more accessible, sociable and sustainable cities. In turn, the book compares new tools and research methodologies for tackling complex issues concerning the ties between lighting, people and the city. Moreover, it presents a series of case studies to provide an in-depth understanding of the influence of urban lighting in terms of luminous atmosphere perception, positive social affect, social enhancement, accessibility and hospitability. Lastly, the book proposes a multidisciplinary qualitative and quantitative methodology for assessing the spatial experience of outdoor lighting.

Designed for a nonmathematical undergraduate optics course addressed to art majors, this four-part treatment discusses the nature and manipulation of light, vision, and color. Questions at the end of each chapter help test comprehension of material, which is almost completely presented in a nonmathematical manner. 170 black-and-white illustrations. 1983 edition.
