Abstract: A method for producing a neutrons includes triggering a raising or a lowering of a temperature of a pyroelectric crystal of less than about 40° C. to produce a voltage of negative polarity of at least ?100 keV on a surface of a deuterated or tritiated target coupled thereto. A deuterium ion source is pulsed to produce a deuterium ion beam. The accelerating of the deuterium ion beam is achieved by accelerating voltage of the pyroelectric crystal toward the deuterated or tritiated target to produce neutrons. Furthermore, the pyroelectric crystal, the deuterated or tritiated target, and the deuterium ion source are coupled to a common support. The method also includes throwing the common support housing the pyroelectric crystal, the deuterated or tritiated target, and the deuterium ion source near an unknown threat for identification thereof.

Abstract: Disclosed is a system, method, and computer program product for performing semantic analysis and creating topics with regards to social data. A user interface is provided that allows the user to view and interact with to view and control the process/mechanism or creating topics. The user interface allows the user to create one or more text-based filters and metadata filters based on which social data for each topic is filtered.
