Available in PDF, EPUB and Kindle. Book excerpt: As the twentieth century draws to a close, it is time to look back on an epoch of widespread turmoil, including two world wars, the end of the colonial era in world history, and a large number of international crises and conflicts. This book is designed to shed light on the causes and consequences of military-security crises since the end of World War I, in every region, across diverse economic and political regimes, and cultures. The primary aim of this volume is to uncover patterns of crises, conflicts and wars and thereby to contribute to the advancement of international peace and world order. The culmination of more than twenty years of research by Michael Brecher and Jonathan Wilkenfeld, the book analyzes crucial themes about crisis, conflict, and war and presents systematic knowledge about more than 400 crises, thirty-one protracted conflicts and almost 900 state participants. The authors explore many aspects of conflict, including the ethnic dimension, the effect of different kinds of political regimes--notably the question whether democracies are more peaceful than authoritarian regimes, and the role of violence in crisis management. They employ both case studies and aggregate data analysis in a Unified Model of Crisis to focus on two levels of analysis--hostile interactions among states, and the behavior of decision-makers who must cope with the challenge posed by a threat to values, time pressure, and the increased likelihood that military hostilities will engulf them. This book will appeal to scholars in history, political science, sociology, and economics as well as policy makers interested in the causes and effects of crises in international relations. The rich data sets will serve researchers for years to come as they probe additional aspects of crisis, conflict and war in international relations. Michael Brecher is R. B. Angus Professor of Political Science, McGill University. Jonathan Wilkenfeld is Professor and Chair of the Department of Government and Politics, University of Maryland. They are the coauthors of Crises in the Twentieth Century: A Handbook of International Crisis, among other books and articles.

Download or read book Biomechanical Analysis of the Index Finger Motion for Optimal Trigger Design Using Cadaver Experiments written by Joonho Chang and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A trigger grip has been usually used to operate powered hand tools and helps operators to control powered hand tools quickly and simply by reducing manual force requirements. However, operating the trigger excessively and repeatedly may let workers be exposed to work related musculoskeletal disorders (WRMSDs) such as trigger finger or carpal tunnel syndrome. Thus, the proper design of a trigger to reduce excessive and repetitive finger motions is required to prevent these WRMSDs. Although there have been a variety of related biomechanical analyses on the index finger or a trigger design, little research focusing on biomechanical interaction between index finger motions and trigger mechanism exists. However, they even have limits to show detailed biomechanical interaction between the index finger and triggers. Therefore, more specific and detailed biomechanical analyses focusing on the index finger mechanism during triggering are required.The present study aims to conduct a biomechanical analysis on the index finger mechanism during triggering action using cadaver experiments. The specific objectives of the study include 1) developing a two-dimensional biomechanical static model for the index finger which accounts for index finger force mechanism while operating a trigger, 2) building an index finger motion simulator to support and control a cadaver hand, 3) conducting cadaver experiments to observe the relationship of external trigger forces to the internal tendon forces depending on different external force contact locations, trigger grip spans, FDP to FDS tendon force ratios, and handle grip spans, 4) validating the proposed biomechanical model, and 5) recommending optimal trigger grip span, optimal contact location for finger triggering, and optimal handle grip span for trigger and pistol designs in terms of force efficiency between externally generated trigger forces and internal tendon forces.The index finger motion simulator was developed for cadaver experiments. The primary purpose of this simulator was to support and control a cadaver hand for observing relationship between internal tendon forces and external trigger forces, during triggering. The simulator was comprised of five essential parts: 1) the support frame to secure the specimens, 2) the motion delivery unit to control FDP and FDS tendons in the specimens 3) the data acquisition system to measure internal tendon forces and external triggering forces, 4) the vision system to obtain joint flexion angles on the index finger, and 5) the operation program to control the simulator and save the results of the experiments. The cadaver experiments for index finger's triggering motion was conducted with the index finger motion simulator. Five fresh-frozen right human cadaveric hand specimens (average age = 46; SD = 5.7) without apparent musculoskeletal disorders and anatomical abnormalities were employed in the study. And the experiments consisting of two phases investigated triggering forces by the index finger as function of 1) total internal tendon forces (FDP + FDS; 40, 70, and 100 N), 2) FDP to FDS tendon force ratios (1 to 1, 1.5 to 1, 2 to 1, and 3 to 1), 3) trigger grip spans (40, 50, and 60 mm), 4) three different contact locations (F1 = the middle of the distal phalange; F2 = the distal edge of the medial phalange; F3 = the middle of the medial phalange) between a trigger and the index finger, and 5) handle grip spans (40, 50, and 60 mm) for the middle, ring, and little fingers; Phase I observed effects of 1), 2), 3), and 4), while Phase II investigated effect of 5). Also, force efficiencies were computed based on their internal tendon force to external triggering force ratios. As a result, the following key findings were found from the experiments: 1) FDP to FDS tendon force ratios didn't affect triggering forces by the index finger, 2) triggering forces increased significantly while total internal tendon force increased from 40 to 100 N, 3) The maximum triggering forces were found at 50 mm trigger grip span and the triggering forces at 60 and 40 mm trigger grip spans followed it in turn, 4) triggering forces increased significantly while external force contact location moved proximally from F1 to F3, and 5) 50 mm handle grip span showed the maximum triggering forces and 40 and 60 mm handle grip spans followed it in turn. Also, force efficiencies found the following important features: 1) approximately 10 to 30% of internal tendon forces could be converted into external triggering forces while triggering and 2) force efficiencies declined gradually while total internal tendon force increased from 40 to 100 N. A biomechanical index finger model for triggering was developed to observe relationships between internal tendon forces and externally generated triggering forces, based upon the index finger anatomy; three mathematical models on the three external force contact locations, F1, F2, and F3, were developed based on biomechanical assumptions and conditions of static equilibrium. Also, the models were simulated mathematically based on the unknown variables determined by the experimental conditions, in order to evaluate the validity of the models. Consequently, the simulation results showed high similarities to the results of the experiments: 1) the estimated triggering forces increased significantly while total internal tendon force increased from 40 to 100 N, 2) The maximum estimated triggering forces were found at 50 mm trigger grip span and the triggering forces at 60 and 40 mm trigger grip spans followed it in turn, and 3) the estimated triggering forces increased gradually while external force contact location moved proximally from F1 to F3. In sum, the models predicted similar triggering force patterns to the triggering forces measured in the experiments. However, overall, triggering forces were over-estimated by the models, except for at F1 contact location; relatively accurate triggering forces were estimated at F1 contact location, but the models predicted triggering forces two and three times higher than the measured triggering forces at F2 and F3 contact locations, respectively.Finally, the present study provided design recommendations for an optimal one-finger trigger design. The following four design guidelines were defined based on the results of the cadaver experiments: 1) a force requirement to activate a trigger should be set as low as possible, 2) a trigger grip may afford users to use the medial phalange, 3) 50 mm trigger grip span is generally recommended as the optimal trigger grip span to accommodate most people, and 4) 50 mm is recommended as the trigger handle grip span.

Available in PDF, EPUB and Kindle. Book excerpt: The Trigger Mechanism is the second book in the Camp Valor series by the #1 New York Times bestselling co-author of American Sniper, Scott McEwen. When, Jalen, a young gamer, puts on a set of VR goggles and logs into an online video game, he enters a digital world where, as in most games, points are awarded for kills. Only this time, unbeknownst to Jalen, the game has been reengineered by a cyberterrorist known as Encyte so that real human lives are taken with the click of a button. When Jalen logs off, he learns he’s just killed fifty-three innocent people. Wyatt Brewer, Camp Valor’s top camper, is tapped to investigate and see if a link exists between Encyte and The Glowworm Gaming Network, which Wyatt helped dismantle the previous summer. Wyatt is still reeling from the losses inflicted by Glowworm and by the betrayal of his mentor, Sargent Halsey. When Wyatt meets Jalen, he finds a clue, and Julie Chen, a teenage prodigy and gaming superstar known as Hi_Kyto becomes the leading suspect. Wyatt knows he’ll need Jalen’s help if he has any chance of penetrating the gaming world and getting close to Hi_Kyto. And Jalen will need Camp Valor if he’s going to have any chance of rebuilding his life and finding redemption. But as the summer season starts at Valor, the Department of Defense threatens to shut the secret program down. A reclusive billionaire and Camp Valor alum offers a way forward—funded by him but without Valor for protection. Jalen and Wyatt are forced to consider going out on their own if they want bring Halsey to justice and to stop Encyte.
