American land surveying has a dilemma; it's called the "pincushion corner." This is a name used to describe the phenomena of multiple boundary monuments being set by land surveyors when only one boundary corner exists under the law. The pincushion has not gone unnoticed by the legal profession and the general public. It is now common knowledge that no two surveyors can agree on the location of any given property corner. The pincushion is physical proof of that notion. Not only is the pincushion becoming a public relations disaster for the profession, it is causing those who might otherwise consider commissioning a survey to decide otherwise. And herein lies the dilemma; no one wants to hire the surveyor because of the way surveying is practiced, the pincushion being emblematic of that practice. This book explores the effect of the pincushion, how the phenomena started, why it exists, and remedies to end the practices that allow the pincushion corner to not only exist, but to flourish.

Providing a balanced, insightful approach to both the learning of the science and technology of biomaterials, this text serves as a key reference for practitioners who are involved in the applications of materials in medicine. --

This book explains how medical photography is part of the workflow in many specialties: it is needed for registries, to preserve information, for follow up, second opinion and teaching, among others. The book gathers information on this field, providing valuable practical tips for those that have never used photography for medical uses as well as those who use it regularly. Covering specialities ranging from dermatology, plastic surgery, dentistry, ophthalmology and endoscopy to forensic medicine, specimen photography and veterinary medicine, it highlights standardization for each procedure and relevance to ethical, patients’ perception of medical photography, cybersecurity and legal aspects. The book also presents practical sections explaining how to organize a photographic file, coding, reimbursement, compliance, use of social media and preservation as well as in depth concepts on sharp focus on blurred vision. This volume will appeal to all clinicians and practitioners interested in acquiring a high level of technical skill in medical photography.

The Fourth Edition of this text provides a clear understanding of the physics principles essential to getting maximum diagnostic value from the full range of current and emerging imaging technologies. Updated material added in areas such as x-ray generators (solid-state devices), xerography (liquid toner), CT scanners (fast-imaging technology) and ultrasound (color Doppler).

What is Cylindrical Perspective Cylindrical perspective is a form of distortion caused by fisheye and panoramic lenses which reproduce straight horizontal lines above and below the lens axis level as curved while reproducing straight horizontal lines on lens axis level as straight. This is also a common feature of wide-angle anamorphic lenses of less than 40mm focal length in cinematography, as well as the basis for creating the 146-degree peripheral vision of Cinerama when projected into a matching, cylindrically curved screen. How you will benefit (I) Insights, and validations about the following topics: Chapter 1: Cylindrical perspective Chapter 2: Optical aberration Chapter 3: Map projection Chapter 4: Panoramic photography Chapter 5: Distortion (optics) Chapter 6: Image stitching Chapter 7: Cylindrical lens Chapter 8: Image rectification Chapter 9: Keystone effect Chapter 10: Vertical and horizontal (II) Answering the public top questions about cylindrical perspective. (III) Real world examples for the usage of cylindrical perspective in many fields. Who this book is for Professionals, undergraduate and graduate students, enthusiasts, hobbyists, and those who want to go beyond basic knowledge or information for any kind of Cylindrical Perspective.

This is the first book to expose a crucial aspect of the cover-up of the JFK assassination conspiracy: the doctoring of the Zapruder film, allegedly a 27-second home movie shot by Abraham Zapruder in Dealey Plaza. The evidence for alteration of the Zapruder movie takes many forms, including inconsistencies with eyewitness testimony, discrepancies with other films and photographs, impossible movements within the time-frame of the movie, contradictions between the movie and the physical layout of Dealey Plaza, and the multiple versions of the movie itself. This book brings together all the leading authorities within the assassination research community, including David Healy, authority on technical processes of film production; Jack White, who for forty years has made a special study of the JFK assassination movies and photographs; John Costella, Ph.D., a physicist and engineer with a background in optics, the properties of light, and moving objects; and David W. Mantick, Ph.D., the foremost expert on the medical evidence in the JFK assassination.
