Light Agricultural and Industrial Structures: Analysis and Design

by G. Nelson H. B. Manbeck N. F. Meador

This book is an outgrowth of a much earlier book, Farm Structures, by H. J. Barre and L. L. Sammet, published by John Wiley & Sons in 1950 as one of a series of textbooks in agricultural engineering spon­ sored by the Ferguson Foundation, Detroit, Michigan. Light Agricul­ tural and Industrial Structures: Analysis and Design will be useful as an undergraduate student textbook for junior-or senior-level compre­ hensive courses on structural analysis and design in steel, wood, and concrete, and as a reference work for practicing engineers. Emphasis is on basic analysis and design procedures. The book should be useful in any country where there is a need to design structures for agricul­ tural production and processing. It is assumed that readers have had prerequisite course work in engineering mechanics and strength of materials as typically taught to undergraduate engineering students. The scope of this book is wide; it might be difficult for instructors and students to cover all of the chapters in a typical three credit-hour course. The instructor will need to assess his own situation and scheduling constraints. More or less time could be spent on chapters one through five, depending on the capability the students already have in analysis of statically deter­ minate and indeterminate structures. Two to three weeks might then be allocated for study of each of the last six chapters dealing with design in steel, reinforced concrete, and wood.

Light and Plant Growth (Topics in Plant Physiology #1)

by J.W. Hart

There are many recent works on the topic of light and plant growth. These have not only been written by experts, but are also, in the main, written for experts (or, at least, for those who already have a fair understanding of the subject). This book has its origins in a six-week course in plant photophysiology, and its aim is to provide an introduction to the subject at an advanced undergraduate level. The imagined audience is simply a student who has asked the questions: In what ways does light affect plant growth, and how does it do it? The book is limited to aspects of photomorphogenesis. Photo­ synthesis is only considered where its pigments impinge on photo­ morphogenic investigations, or where its processes provide illustrative examples of particular interactions between light and biological material. Chapter 1 gives a general account of the various ways in which light affects plant development, and introduces topics which are subsequently covered in greater detail. In all the chapters, are special topic 'boxes', consisting of squared-off sections of text. These are simply devices for presenting explanatory background material, or material that I myself find particularly intriguing.

Light Detectors, Photoreceptors, and Imaging Systems in Nature

by Jerome J. Wolken

The influence of light on the lives of living organisms is all-pervasive, affecting movement, vision, behavior, and physiological activity. This book is a biophysically grounded comparative survey of how animals detect light and perceive their surroundings. Included are discussions of photoreceptors, light emitters, and eyes. The book focuses in particular on the kinds of optical systems that have evolved, beginning with unicellular organisms that detect and respond to light through to more advanced and complex designs for imaging. The relevance of these studies extends beyond biology, since these findings can be used to help develop photoreceptor energy conversion and information systems, and optical imaging devices with a wide range of everyday applications. The book will appeal to biophysicists, photobiologists, bioengineers, neuroscientists, and all researchers working in the area of vision and visual optics.

Light Driven Micromachines

by George K. Knopf Kenji Uchino

In Light Driven Micromachines, the fundamental principles and unique characteristics of light driven material structures, simple mechanisms and integrated machines are explored. Very small light driven systems provide a number of interesting features and unique design opportunities because streams of photons deliver energy into the system and provide the control signal used to regulate the response of the micron sized device. Through innovative material design and clever component fabrication, these optically powered tiny machines can be created to perform mechanical work when exposed to varying light intensity, wavelength, phase, and/or polarization. The book begins with the scientific background necessary to understand the nature of light and how light can initiate physical movement by inducing material deformation or altering the surrounding environment to impose micro-forces on the actuating mechanisms. The impact of physical size on the performance of light driven mechanisms and machines is discussed, and the nature of light–material interactions is reviewed. These interactions enable very small objects and mechanical components to be trapped and manipulated by a focused light beam, or produce local temperature gradients that force certain materials to undergo shape transformation. Advanced phase transition gels, polymers, carbon-based films and piezoelectric ceramics that exhibit direct light-to-mechanical energy conversion are examined from the perspective of designing optically driven actuators and mechanical systems. The ability of light to create photothermal effects that drive microfluidic processes and initiate the phase transformation of temperature sensitive shape memory materials are also explored in the book. This compendium seeks to inspire the next generation of scientists and engineers by presenting the fundamental principles of this emerging interdisciplinary technology and exploring how the properties of light can be exploited for microfluidic, microrobotic, biomedical and space applications.

Light Field Sampling (Synthesis Lectures on Image, Video, and Multimedia Processing)

by Cha Zhang Tsuhan Chen

Light field is one of the most representative image-based rendering techniques that generate novel virtual views from images instead of 3D models. The light field capture and rendering process can be considered as a procedure of sampling the light rays in the space and interpolating those in novel views. As a result, light field can be studied as a high-dimensional signal sampling problem, which has attracted a lot of research interest and become a convergence point between computer graphics and signal processing, and even computer vision. This lecture focuses on answering two questions regarding light field sampling, namely how many images are needed for a light field, and if such number is limited, where we should capture them. The book can be divided into three parts. First, we give a complete analysis on uniform sampling of IBR data. By introducing the surface plenoptic function, we are able to analyze the Fourier spectrum of non-Lambertian and occluded scenes. Given the spectrum, we also apply the generalized sampling theorem on the IBR data, which results in better rendering quality than rectangular sampling for complex scenes. Such uniform sampling analysis provides general guidelines on how the images in IBR should be taken. For instance, it shows that non-Lambertian and occluded scenes often require a higher sampling rate. Next, we describe a very general sampling framework named freeform sampling. Freeform sampling handles three kinds of problems: sample reduction, minimum sampling rate to meet an error requirement, and minimization of reconstruction error given a fixed number of samples. When the to-be-reconstructed function values are unknown, freeform sampling becomes active sampling. Algorithms of active sampling are developed for light field and show better results than the traditional uniform sampling approach. Third, we present a self-reconfigurable camera array that we developed, which features a very efficient algorithm for real-time rendering and the ability of automatically reconfiguring the cameras to improve the rendering quality. Both are based on active sampling. Our camera array is able to render dynamic scenes interactively at high quality. To the best of our knowledge, it is the first camera array that can reconfigure the camera positions automatically.

A ‘Light’ Guide to Energy Savings in Transport

by Conor Molloy

This book is a practical guide to finding and delivering energy savings opportunities in transport operations for professional energy managers and energy auditors. Globally, transport is one of the fastest growing energy consumers and emitters of greenhouse gases, predominantly CO2. The transport sector is also changing quickly ("more change in the last 5 years than in the last 50" – Mary Barra, CEO General Motors). After distance, unladen vehicle weight is the biggest driver of energy consumption in transport, hence this book is called the ‘light’ guide – tongue in cheek. Be warned transport is a huge and complex topic. This practical guide from the convener of EN16247-4:2014, the first European energy audit standard for transport, takes a pragmatic approach to delivering measurable energy and emissions reductions in transport operations. Lessons learnt from the author’s 17 years of experience in persuading operators to deliver measured energy savings in transport are interwoven with tools, tips and shortcuts. These will help energy managers and auditors deliver effective transport energy audits that identify opportunities, prompting action, measured savings and, most importantly, being invited back!

Light, Lasers, and Synchrotron Radiation: A Health Risk Assessment (Nato Science Series B: #242)

by Martino Grandolfo A. Rindi D. H. Sliney

This volume contains the formal record of the lectures presented at the 9th Course of the International School of Radiation Damage and Protection held at the "E . Majorana" International Centre for Scientific Culture in Erice (Italy) from May 9 to May 20, 1989. This course was the last of a series of 4 courses, started in 1981, that were dedicated to the assessment of risk hazard from non-ionizing radiation. The proceedings of these courses were all published by Plenum Press with the following headings: 1) M. Grandolfo, S. M. Michaelson and A. Rindi, Eds. : "Biological Effects and Dosimetry of Nonionizing Radiation; Radiofrequency and Microwave Energy", Plenum Press, New York, NATO ASI Series A Life Sciences, Vo1. 49 (1983); 2) M. Grandolfo, S. M. Michaelson and A. Rindi, Eds. : "Biological Effects and Dosimetry of Static and ELF Electromagnetic Fields", Plenum Press, New York, E. Majorana International Science Series, Life Sciences, Vol. 19 (1985) ; 3) M. H. Repacholi, M. Grandolfo and A. Rindi, Eds. : "Ultrasound; medical applications, biological effects and hazard potential", Plenum Press, New York (1987). We hope that all these volumes together may represent a complete textbook and a reference for the students and scientists interested in the physics, biology, measurement and dosimetry, health effects and standard setting, in short, the risk assessment of that wide field of radiation presently classified as non-ionizing radiation. We are indebted to the Associa?ione Italiana Protezione dalle Radiazioni (AIRP), The Internat:l.

Light-Matter Interaction: Physics and Engineering at the Nanoscale

by John Weiner Frederico Nunes

Light-matter interaction is pervasive throughout the disciplines of optical and atomic physics, condensed matter physics, electrical engineering, and now increasingly in biology and medicine with frequency and length scales extending over many orders of magnitude. Deep earth and sea communications use frequencies of a few tens of Hz, and X-ray imaging requires sources oscillating at hundreds of petaHz. This book provides advanced undergraduates, graduate students and researchers from diverse disciplines with the principal tools required to understand and contribute to rapidly advancing developments in light-matter interaction, centred at optical frequencies and length scales from a few hundred nanometres to a few hundredths of a nanometre. This book deploys an arsenal of powerful analytic tools to render this multidisciplinary subject in unique form, not encountered in standard Physics or Electrical Engineering text books. This new edition has been substantially expanded with almost 200 pages of new material. Several new and extended chapters treat momentum flow between fields and matter, metamaterials, and atom-optical forces applied to atomic and molecular cooling and trapping.
