Book excerpt: There are problems with the compatibility of spectacles and certain helmet mounted electro-optical visual display systems. The incompatibility has been partially resolved with single vision contact lenses. However, these contact lenses have not helped senior aviators, who must wear bifocal glasses due to their presbyopia. The purpose of this study was to compare the performance of bifocal soft contact lenses with that of bifocal spectacle lenses to determine if contact lenses are an option for helping older aviators meet the visual requirements needed to fly military aircraft. Seventeen volunteer presbyopic aviators from Fort Rucker were fitted with five bifocal soft contact lens combinations and bifocal glasses. A four-phase investigation was conducted: a clinical phase involving the fitting of the bifocal contact lenses; a laboratory phase involving measurements of visual functions; a simulator phase involving measures of visual performance in simulated flight conditions; and an operational phase consisting of subjective responses regarding in-flight use of bifocal contact lenses. In general, vision in the best performing bifocal contact lenses typically was slightly reduced from vision in bifocal spectacles. The amount of the reduction, and whether it was clinically significant, depended on the refractive error of the subject (myopes generally performed better), the add group of the subject (low add group subjects performed better), and the type of bifocal contact lens. Aviators performed flight simulation maneuvers better in bifocal contact lenses than in bifocal glasses, and they evaluated their own ease of vision while performing aviation duties to be much easier in bifocal contact lenses than in bifocal glasses. In actual flight operations, each aviator preferred bifocal contact lenses over bifocal spectacles. Bifocal soft contact lenses are an acceptable

Book excerpt: Given its characteristics and the complexity of its use and its environment, the helicopter is exposed to damage and a whole series of measures can be previewed to alientate this risk. The presentations concentrated on five main topics: 1. Crew training; 2. The different conditions of use; 3. The psycho-physiological component; 4. Survival equipment and methods; and 5. Accidents and their prevention. A careful reading of the papers presented at the symposium will enable both specialists and decision-makers to make a summary assessment of the constraints of the missions on the one hand, and on the other, of the new methods of protection and training and the new technologies which will enable aircrew to carry out their missions in a safer environment. In addition, they will perhaps discover that helicopter operation can be optimised by a series of different devices and above all by judicious matching of "type of helicopter-type of aircrew training-type of additional on-board equipment".

Available in PDF, EPUB and Kindle. Book excerpt: This manual is intended for use by all Army crewmembers in meeting requirements set forth in Army Regulation 95-1, Training Circular 1-210, and other appropriate aircrew training manuals. Lessons learned from previous military conflicts and recent contingency operations have caused changes in Army aviation doctrine. With the development of more sophisticated aircraft and weapons systems, Army crewmembers must be capable of operating these systems around the clock, in austere environments, and under adverse conditions. The hazards of stress and fatigue in combat operations and concept of operations will eventually take a toll in aircrew performance and could jeopardize mission accomplishment unless crewmembers are trained to recognize and understand these hazards. Proper training prepares crewmembers and prevents stress and fatigue from reducing mission effectiveness, thereby increasing their chances of survival. Training Circular 3-04.93 provides crewmembers with an understanding of the physiological responses that can occur in the aviation environment. It also describes the effects of the flight environment on individual mission accomplishment. In addition, this publication outlines essential aeromedical training requirements (in Chapter 1) that assist commanders and flight surgeons in conducting aeromedical education for Army crewmembers. Subject areas addressed are by no means all inclusive but are presented to assist crewmembers in increasing performance and efficiency. This publication applies to the Active Army, the Army National Guard/Army National Guard of the United States, and the United States Army Reserve unless otherwise stated.

The contemporary world they live in is not quite this one, but much like Berkeley, California, and the two graduate students are trying to finish their degrees and get jobs. It doesn't help that their unpredictable advisor Roland is a mad mathematical genius who has figured out a way to predict isolated and specific bits of the future that can cause a lot of trouble. . .and he's starting to see monsters in mirrors. Bela and Paul start to mess around with reality, and when that happens, all heaven and hell break loose. Those monsters of Roland's were really there, but who are they? This novel is a romantic comedy with a whole corkscrew of SF twists. At the publisher's request, this title is being sold without Digital Rights Management software (DRM) applied.

Book excerpt: A comprehensive treatment of the skills and techniques needed for visual psychophysics, from basic tools to sophisticated data analysis. Vision is one of the most active areas in biomedical research, and visual psychophysical techniques are a foundational methodology for this research enterprise. Visual psychophysics, which studies the relationship between the physical world and human behavior, is a classical field of study that has widespread applications in modern vision science. Bridging the gap between theory and practice, this textbook provides a comprehensive treatment of visual psychophysics, teaching not only basic techniques but also sophisticated data analysis methodologies and theoretical approaches. It begins with practical information about setting up a vision lab and goes on to discuss the creation, manipulation, and display of visual images; timing and integration of displays with measurements of brain activities and other relevant techniques; experimental designs; estimation of behavioral functions; and examples of psychophysics in applied and clinical settings. The book's treatment of experimental designs presents the most commonly used psychophysical paradigms, theory-driven psychophysical experiments, and the analysis of these procedures in a signal-detection theory framework. The book discusses the theoretical underpinnings of data analysis and scientific interpretation, presenting data analysis techniques that include model fitting, model comparison, and a general framework for optimized adaptive testing methods. It includes many sample programs in Matlab with functions from Psychtoolbox, a free toolbox for real-time experimental control. Once students and researchers have mastered the material in this book, they will have the skills to apply visual psychophysics to cutting-edge vision science.
