    Strategy and History: Essays on Theory and Practice

    Get PDF
    This volume is largely successful not only in emphasizing the continuity and wisdom of Colin Gray’s long-standing defense of the study of strategy but in capturing his delight in skewering the latest intellectual fads in both American and British security theory. Strategy and History is a rich and occasionally pro- vocative read for any student of strat- egy, military issues, or international relations, and it reinforces the need to study strategy—the relationship be- tween military force and desired politi- cal objectives

    Automated Propulsion Data Screening demonstration system

    A fully-instrumented firing of a propulsion system typically generates a very large quantity of data. In the case of the Space Shuttle Main Engine (SSME), data analysis from ground tests and flights is currently a labor-intensive process. Human experts spend a great deal of time examining the large volume of sensor data generated by each engine firing. These experts look for any anomalies in the data which might indicate engine conditions warranting further investigation. The contract effort was to develop a 'first-cut' screening system for application to SSME engine firings that would identify the relatively small volume of data which is unusual or anomalous in some way. With such a system, limited and expensive human resources could focus on this small volume of unusual data for thorough analysis. The overall project objective was to develop a fully operational Automated Propulsion Data Screening (APDS) system with the capability of detecting significant trends and anomalies in transient and steady-state data. However, the effort limited screening of transient data to ground test data for throttle-down cases typical of the 3-g acceleration, and for engine throttling required to reach the maximum dynamic pressure limits imposed on the Space Shuttle. This APDS is based on neural networks designed to detect anomalies in propulsion system data that are not part of the data used for neural network training. The delivered system allows engineers to build their own screening sets for application to completed or planned firings of the SSME. ERC developers also built some generic screening sets that NASA engineers could apply immediately to their data analysis efforts

    Severe traumatic injury during long duration spaceflight: Light years beyond ATLS

    Get PDF
    Traumatic injury strikes unexpectedly among the healthiest members of the human population, and has been an inevitable companion of exploration throughout history. In space flight beyond the Earth's orbit, NASA considers trauma to be the highest level of concern regarding the probable incidence versus impact on mission and health. Because of limited resources, medical care will have to focus on the conditions most likely to occur, as well as those with the most significant impact on the crew and mission. Although the relative risk of disabling injuries is significantly higher than traumatic deaths on earth, either issue would have catastrophic implications during space flight. As a result this review focuses on serious life-threatening injuries during space flight as determined by a NASA consensus conference attended by experts in all aspects of injury and space flight

    Središnja tema rada usmjerena je na raščlambu spisa pohranjenog u Državnom arhivu u Mlecima (fond: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) koji se odnosi na događaj iz 1748. godine u korčulanskom selu Žrnovo, kada su mještani – vjerujući da su se pojavili vampiri – oskvrnuli nekoliko mjesnih grobova. U radu se podrobno iznose osnovni podaci iz spisa te rečeni događaj analizira u širem društvenom kontekstu i prate se lokalna vjerovanja.The main interest of this essay is the analysis of the document from the State Archive in Venice (file: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) which is connected with the episode from 1748 when the inhabitants of the village Žrnove on the island of Korčula in Croatia opened tombs on the local cemetery in the fear of the vampires treating. This essay try to show some social circumstances connected with this event as well as a local vernacular tradition concerning superstitions

    India’s Grand Strategy: Some Preliminary Thoughts

    No full text
    India’s emergence as one of the great economic powers in the international system and its military strength position it to be a major player in the international system in the twenty-first century. However, its current policies, rooted in a vision of India’s role in the international order that once reflected a consensus of Indian elites, appear to reflect a mismatch between its growing means and its overall role in international affairs. The emergence of “new thinking” and debates are gradually breaking down the consensus of India’s founding generations. Drivers of change are many, but it remains to be seen which tips India from a passive regional power to a more assertive global one

    For more about the East-West Center, see http://www.eastwestcenter.org/Timothy D. Hoyt, the John Nicholas Brown Chair of Counterterrorism at the U.S. Naval War College, explains that "The US-China competition, in particular, is regularly compared to the Cold War between the United States and the Soviet Union." However, "...The Cold War analogy should be used with great caution. It is relatively anomalous in the history of international relations ...
