Abstract: Computer-implemented methods and computer-readable media are disclosed for processing call-for-service data to facilitate queries and reports to enhance usefulness of call-for-service data. In one embodiment, a computer-implemented method performable by a computer system includes receiving at a computer system data for a plurality of calls-for-service. Individual data for an individual call-for-service includes one or more fields storing information relating to the call-for-service. Based on the information stored within the one or more fields of the individual data, one or more supplemental classifiers are automatically identified. The one or more supplemental classifiers are associated with the individual data. The one or more supplemental classifiers associated with the individual data enable the individual call-for-service to be identified when the one or more supplemental classifiers match one or more specified criteria.

Abstract: A system for treatment of exhaust emissions from a compression-ignited internal combustion engine comprises (A) a superatmospheric-pressurized source of gaseous oxygen, (B) an inlet for the gaseous oxygen of component (A) where the exhaust emissions from the engine flow past the inlet and form a mixture with the gaseous oxygen from the inlet, and (C) a diesel particulate filter or catalyzed diesel particulate filter through which the mixture of engine exhaust emissions and gaseous oxygen flows, where the oxygen content of the mixture is greater than the oxygen content of the exhaust emissions from the engine. A method for improving the performance of a diesel particulate filter or catalyzed diesel particulate filter in a compression-ignited internal combustion engine comprises operating the engine and treating the exhaust emissions from the engine with the exhaust emissions treatment system.

Abstract: Apparatus is provided which permits highly accurate remote measurement of methane gas concentrations even in daylight through the use of an extremely narrow spectral filter centered on the Q-branch of the methane absorption band at 3.3 microns and through the use of cooperating comparison channels with digital processing for real time correction of data to compensate for surface temperature, atmospheric temperature and atmospheric water absorption factors.
