Collision Detection in Interactive 3D Environments

by Gino van den Bergen

The heart of any system that simulates the physical interaction between objects is collision detection-the ability to detect when two objects have come into contact. This system is also one of the most difficult aspects of a physical simulation to implement correctly, and invariably it is the main consumer of CPU cycles. Practitioners, new to the f

Collisional Narrowing and Dynamical Decoupling in a Dense Ensemble of Cold Atoms (Springer Theses)

by Yoav Sagi

Ultra-cold atomic ensembles have emerged in recent years as a powerful tool in many-body physics research, quantum information science and metrology. This thesis presents an experimental and theoretical study of the coherent properties of trapped atomic ensembles at high densities, which are essential to many of the aforementioned applications. The study focuses on how inter-particle interactions modify the ensemble coherence dynamics, and whether it is possible to extend the coherence time by means of external control. The thesis presents a theoretical model which explains the effect of elastic collision of the coherence dynamics and then reports on experiments which test this model successfully in the lab. Furthermore, the work includes the first implementation of dynamical decoupling with ultra-cold atomic ensembles. It is demonstrated experimentally that by using dynamical decoupling the coherence time can be extended 20-fold. This has a great potential to increase the usefulness of these ensembles for quantum computation.

Color Desktop Printer Technology (Optical Science and Engineering)

by Mitchell Rosen Noboru Ohta

Printing traces its roots back for centuries, and the invention of moveable type changed the world. However, until the advent of the computer, printing remained a costly and time-consuming operation. From the first humble dot matrix to modern inkjet, laser, and dye sublimation printers, desktop printing has brought low-cost, high quality printing out of the large presses and into the home and office. Color Desktop Printer Technology provides an overview of the current state of the technology, examining both current and emerging applications.With expert contributors from leading companies and universities in the US and Japan, this book examines the color desktop printer from every angle. It begins with an introduction to the basic principles of color printing and the concepts of document and image quality. An overview of the historical background, current trends, and future directions places the technology in its business and market context. The book then devotes four chapters to the major platform: inkjet, laser printer, thermal transfer, and film recording. The last two chapters focus on color management and the quickly developing spectral printing technology.Laying a foundation for continued development and innovation in this ubiquitous field, Color Desktop Printer Technology is fundamental enough to be enjoyed by interested laypersons, yet detailed enough to satisfy the practicing engineer.

Color in Electronic Display Systems

by Michael E. Miller

This book explores the principles, design, and image processing of multi-primary displays, and introduces the reader to the intricacies of the typical imaging pathways which influence display design and the perception of color within a display system. Early chapters introduce the concepts behind human perception, color science, and lighting, which are necessary to fully understand multi-primary displays. The reader is also introduced to digital capture and transmission systems to better understand the ecosystem in which multi-primary displays exist. Subsequent chapters introduce the reader to current display technologies, including LCD, OLED, and inorganic LED displays. The working principles, performance, and upcoming advances are discussed for each of these technologies to provide the reader with a clear understanding of the tradeoffs which are necessary when considering multi-primary displays. This discussion is followed by an in-depth discussion of the image processing technology necessary to implement multi-primary displays. The book concludes with chapters that clearly discuss the advantages and limitations of multi-primary displays for direct view, virtual reality, and augmented reality displays. The book provides a broad viewpoint across the entire display ecosystem, explaining the interactions among system components to provide a rationale for the further development of multi-primary displays. Whether the reader is interested in broadening their understanding of display systems or the development of multi-primary displays, the text provides and understandable and practical summary of important display system concepts.

Color in Electronic Displays (Defense Research Series #3)

by David L. Post HeinoWiddel

This book is the product of Research Study Group (RSG) 13 on "Human Engineering Evaluation on the Use of Colour in Electronic Displays," of Panel 8, "Defence Applications of Human and Biomedical Sciences," of the NATO Defence Research Group. RSG 13 was chaired by Heino Widdel (Germany) and consisted of Jeffrey Grossman (United States), Jean-Pierre Menu (France), Giampaolo Noja (Italy, point of contact), David Post (United States), and Jan Walraven (Netherlands). Initially, Christopher Gibson (United Kingdom) and Sharon McFaddon (Canada) participated also. Most of these representatives served previously on the NATO program committee that produced Proceedings of a Workshop on Colour Coded vs. Monochrome Displays (edited by Christopher Gibson and published by the Royal Aircraft Establishment, Farnborough, England) in 1984. RSG 13 can be regarded as a descendent of that program committee. RSG 13 was formed in 1987 for the purpose of developing and distributing guidance regarding the use of color on electronic displays. During our first meeting, we discussed the fact that, although there is a tremendous amount of information available concerning color vision, color perception, colorimetry, and color displays-much of it relevant to display design-it is scattered across numerous texts, journals, conference proceedings, and technical reports. We decided that we could fulfill the RSG's purpose best by producing a book that consolidates and summarizes this information, emphasizing those aspects that are most applicable to display design.

Color Medical Image Analysis (Lecture Notes in Computational Vision and Biomechanics #6)

by M. Emre Celebi Gerald Schaefer

Since the early 20th century, medical imaging has been dominated by monochrome imaging modalities such as x-ray, computed tomography, ultrasound, and magnetic resonance imaging. As a result, color information has been overlooked in medical image analysis applications. Recently, various medical imaging modalities that involve color information have been introduced. These include cervicography, dermoscopy, fundus photography, gastrointestinal endoscopy, microscopy, and wound photography. However, in comparison to monochrome images, the analysis of color images is a relatively unexplored area. The multivariate nature of color image data presents new challenges for researchers and practitioners as the numerous methods developed for monochrome images are often not directly applicable to multichannel images.The goal of this volume is to summarize the state-of-the-art in the utilization of color information in medical image analysis.

Color Theory and Its Application in Art and Design (Springer Series in Optical Sciences #19)

by George A. Agoston

My aim in this introductory text is to present a comprehensible discussion of certain technical topics and recent developments in color science that I believe are of real interest to artists and designers. I treat a number of applications of this knowledge, for example in selection and use of colorants (pigments and dyes) and light. Early in the book I discuss what color is and what its characteristics are. This is followed by a chapter on pertinent aspects of light, light as the stimulus that causes the perception of color. Then the subject of the colors of opaque and transparent, nonfluorescent and fluorescent materials is taken up. There are sections on color matching, color mixture, and color primaries. Chapter 6 introduces the basic ideas that underlie the universal method (CIE) of color specification. Later chapters show how these ideas have been extended to serve other purposes such as systematic color naming, de­ termining complementary colors, mixing colored lights, and demonstrating the limitations of color gamuts of colorants. The Munsell and the Ostwald color systems and the Natural Colour System (Sweden) are explained, and the new Uniform Color Scales (Optical Society of America) are described. Color specification itself is a broad topic. The information presented here is relevant in art and design, for those who work with pigments and dyes or with products that contain them, such as paints, printing inks, plastics, glasses, mosaic tesserae, etc.

Colored Petri Nets for Modeling of Discrete Systems: A Practical Approach With GPenSIM (Asset Analytics)

by Reggie Davidrajuh

This book offers a practical approach to modeling real-world discrete systems and performing analysis. The theory behind the book is the Colored Petri nets, and the tool used for simulations is general-purpose Petri net simulator (GPenSIM). The theory part is kept to a minimum, and more explanation is given to the GPenSIM functions and how they can be used for modeling, simulation, and performance analysis. Real-world industrial systems possess a large number of resources. Modeling these systems with Petri nets would become a problem as they result in huge Petri net models. This book offers a unique solution to this problem by moving resources away from the Petri net model and treating them as variables in the background. Also, the theory and practice put forward in the book help cost estimation of the systems (e.g., manufacturing subsystems).

Colossus: The secrets of Bletchley Park's code-breaking computers

by B. Jack Copeland

At last - the secrets of Bletchley Park's powerful codebreaking computers. This is a history of Colossus, the world's first fully-functioning electronic digital computer. Colossus was used during the Second World War at the Government Code and Cypher School at Bletchley Park, where it played an invaluable role cracking enemy codes. Until very recently, much about the Colossus machine was shrouded in secrecy, largely because the codes that were employed remained in use by the British security services until a short time ago. This book only became possible due to the declassification in the US of wartime documents. With an introductory essay on cryptography and the history of code-breaking by Simon Singh, this book reveals the workings of Colossus and the extraordinary staff at Bletchley Park through personal accounts by those who lived and worked with the computer. Among them is the testimony of Thomas Flowers, who was the architect of Colossus and whose personal account, written shortly before he died, is published here for the first time. Other essays consider the historical importance of this remarkable machine, and its impact on the generations of computing technology that followed.

Colossus: Bletchley Park's Greatest Secret

by Paul Gannon

This is the last untold story of Bletchley Park. Using declassified information, Paul Gannon gives us a gripping account of the invention of the world's first true computer, Colossus.Uncover the secrets of Bletchley Park's code-breaking computers.In 1940, almost a year after the outbreak of the Second World war, Allied radio operators at an interception station in South London began picking up messages in a strange new code. Using science, maths, innovation and improvisation Bletchley Park codebreakers worked furiously to invent a machine to decipher what turned out to be the secrets of Nazi high command. It was called Colossus.What these codebreakers didn't realize was that they had to fashion the world's first true computer. When the war ended, this incredible invention was dismantled and hidden away for almost 50 years. Paul Gannon has pieced together the tremendous story of what is now recognized as the greatest secret of Bletchley Park.'Gannon's book contains a mass of utterly fascinating and largely unknown material about an immensely important wartime project, and is very welcome indeed.' - Brian Rendell, TES
