Supporting Verification of the Comprehensive Nuclear Test Ban Treaty through a Persistent Conversation Interface
Workflow management systems have the potential to make explicit an organization’s implicit need to initiate, track, and execute artifacts and communications about those artifacts. In this sense, these systems can be described as persistent conversation systems, because they are supporting the communication and coordination of distributed actors through a computerbased medium. Furthermore, such ...
متن کاملMachine learning for radioxenon event classification for the Comprehensive Nuclear-Test-Ban Treaty.
A method of weapon detection for the Comprehensive nuclear-Test-Ban-Treaty (CTBT) consists of monitoring the amount of radioxenon in the atmosphere by measuring and sampling the activity concentration of (131m)Xe, (133)Xe, (133m)Xe, and (135)Xe by radionuclide monitoring. Several explosion samples were simulated based on real data since the measured data of this type is quite rare. These data s...
متن کاملClustering Based One-Class Classification for Compliance Verification of the Comprehensive Nuclear-Test-Ban Treaty
Monitoring the levels of radioxenon isotopes in the atmosphere has been proposed as a means of verifying the Comprehensive Nuclear-Test-Ban Treaty (CTBT). This translates into a classification problem, whereby the measured concentrations either belong to an explosion class or a background class. Instances drawn from the explosions class are extremely rare, if not non-existent. Therefore, the re...
متن کاملSeismological Methods of Monitoring Compliance with the Comprehensive Nuclear-Test-Ban Treaty
Seismology provides the key technology for monitoring the occurrence of underground nuclear explosions. A new International Monitoring System (IMS) which is being established under the provisions of the Comprehensive Nuclear-Test-Ban Treaty has begun its work in conjunction with a new International Data Centre in Vienna, and this work is likely to continue to develop even though prospects for e...
متن کاملInternational treaties. Comprehensive test ban: the long road.
Watching the waves IMS also has a smaller network of sensors to listen for explosions carried out underwater, just above the ocean surface, or below the ocean bottom. Sound travels very efficiently in water: Kiyoshi Suyehiro of the Institute for Research on Earth Evolution in Kanagawa, Japan, says a 20-kilogram test charge of TNT was detected 16,000 kilometers away. As a result, IMS has just 11...
