Download or read book A New Method for Producing Automated Seismic Bulletins written by and published by . This book was released on 2015 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given a set of observations within a specified time window, a fitness value is calculated at each grid node by summing station-specific conditional fitness values. Assuming each observation was generated by a refracted P wave, these values are proportional to the conditional probabilities that each observation was generated by a seismic event at the grid node. The node with highest fitness value is accepted as a hypothetical event location, subject to some minimal fitness value, and all arrivals within a longer time window consistent with that event are associated with it. During the association step, a variety of different phases are considered. In addition, once associated with an event, an arrival is removed from further consideration. While unassociated arrivals remain, the search for other events is repeated until none are identified.
Download or read book Automated Bulletin and Seismic Data Retrieval System written by H. M. RACKETS and published by . This book was released on 1963 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Automated Bulletin Program is a system of programs which can be run in sequence on a 'system' oriented computer with a minimum of magnetic tape changes. The system was oriented to obtain a maximum of valid informa tion for research as well as to efficiently provide a seismic bulletin. The concept of operations consists of first picking the arrivals and then checking them against predicted arrivals generated by the computer from USC and GS hypocenter information and travel time curves. Manual bulletins are frequently prepared only after USC and GS information is available to assist in picking arrivals. This latter procedure provides a more complete bulletin, particularly when data analysts are not highly experienced, but introduces a weighting in favor of existing travel time curves. If re-analysis of film strips with aid of PDE data is not performed, scatter in picked arrival times will increase, but should be more closely centered about the actual arrival times. The automated bulletin system will identify phases and collate events analyzed with PDE data more economically than can be done manually, but by operating on raw station data still greater economy can be affected.

Download or read book Earthquake Monitoring and Seismic Hazard Mitigation in Balkan Countries written by Eystein S. Husebye and published by Springer Science & Business Media. This book was released on 2008-03-01 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Balkans are seismically the most active part of Europe due to plate interactions in the Aegean Sea. This book gives a good account of past, present and likely future seismological developments in this area. It describes the tectonic evolution and on-going geodynamic deformations. Coverage also discusses earthquake hazard analysis, topographic site effects, and examines large earthquake hazards in the Aegean and the Marmara seas as practical applications of such procedures.
Download or read book Treatise on Geophysics written by and published by Elsevier. This book was released on 2015-04-17 with total page 5604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treatise on Geophysics, Second Edition, is a comprehensive and in-depth study of the physics of the Earth beyond what any geophysics text has provided previously. Thoroughly revised and updated, it provides fundamental and state-of-the-art discussion of all aspects of geophysics. A highlight of the second edition is a new volume on Near Surface Geophysics that discusses the role of geophysics in the exploitation and conservation of natural resources and the assessment of degradation of natural systems by pollution. Additional features include new material in the Planets and Moon, Mantle Dynamics, Core Dynamics, Crustal and Lithosphere Dynamics, Evolution of the Earth, and Geodesy volumes. New material is also presented on the uses of Earth gravity measurements. This title is essential for professionals, researchers, professors, and advanced undergraduate and graduate students in the fields of Geophysics and Earth system science. Comprehensive and detailed coverage of all aspects of geophysics Fundamental and state-of-the-art discussions of all research topics Integration of topics into a coherent whole

This book was released on 1995-12-13 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Negotiators from more than 35 countries are attempting to formulate a nuclear test-ban treaty and delineate a system from monitoring compliance. This book covers: (1) the desirable characteristics and capabilities of seismic monitoring stations; (2) recommendations on the flow paths and handling of the data, which are to be unclassified; and (3) the types and extent of research that will be needed in the next decade. The primary focus of the book is to explore how basic seismological research and test ban monitoring can be mutually beneficial.

Download or read book Armament Arms Control and Artificial Intelligence written by Thomas Reinhold and published by Springer Nature. This book was released on 2022-10-08 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Looking at a variety of armament sectors, the book examines how Artificial Intelligence (AI) impacts the fields of armament and arms control, how existing arms control measures will be affected by AI, and what new approaches based on AI have been or are currently developed. The significant increase in computing power, the increasing reliance on software, and the advent of (narrow) AI and deep-learning algorithms all have the potential to lead to disruptive changes for military operations and warfare, rendering many classical arms control instruments less effective, or even useless. On the other hand, AI might lead to completely new arms control approaches, raising the effectiveness and reliability of new verification measures. To provide a common understanding, the book starts by presenting a general introduction to the state of the art in artificial intelligence and arms control, and how the two topics are interrelated. The second part of the book looks at examples from various fields of weapon technology, including weapons of mass destruction (WMD), conventional armament, and emerging technologies. The final section offers a cross-cutting perspective based on the examples presented in the second part. This volume will appeal to students and scholars of international relations, as well as policy-makers and practitioners interested in a better understanding of peace and security studies in general, and armament and arms control in particular with a strong focus on AI.
