Abstract: According to an embodiment, three-dimensional (3D) scan data representative of an in-service structure that is captured by a scanning device is accessed by a processor circuit. Based on the 3D scan data, in-service computer-aided design (CAD) data representative of an in-service surface corresponding to the in-service structure is generated by the processor circuit. Based on the in-service CAD data representative of the in-service surface, at least one of a serviceability level or remaining life estimate of the in-service structure is determined.

Abstract: A method and system for using data associated with a first vehicle and a given road segment defined for a road network and using data associated with a second vehicle and the given road segment to determine a multi-vehicle probability value that indicates a probability that the first vehicle and the second vehicle will arrive at a common position of the given road segment simultaneously. The multi-vehicle probability value can be compared to a threshold probability value to determine whether the first vehicle and/or the second vehicle should take a responsive measure to avoid those vehicles arriving at the common position of the given road segment simultaneously. The data associated the first vehicle and the data associated with the second vehicle can each include a respective electronic horizon for that vehicle, and time parameters and probability values associated with those vehicles being on the given road segment.

Abstract: A method of predicting the tendency of a heavy oil feed to generate coke deposits in the FCC riser under a given set of operating parameters in the unit; thus, by utilizing operating parameters appropriate to the feed, the formation of coke deposits in the riser may be minimized. The margin between the theoretical dew point of the hydrocarbon feed established from unit operating parameters and the theoretical mix zone temperature in the feed injection zone of the unit is developed by applying a regression-derived linear model from multiple rigorous model runs. The mix zone of the unit is then operated at a temperature which reduces the level of riser coking predicted from this ascertainable margin or, at least, maintains it within levels which are predictable and acceptable.

Abstract: An improved method and system for storage of data that represent geographic features in a region. The data are organized into parcels each of which contains data that represent those geographic features that are located within a separate one of a plurality of rectangular areas into the region is divided. The method identifies linearly extending features that extend across multiple rectangular areas so that data representing the linearly extending feature can be included in each parcel that contains data that represents a rectangular area in which the linearly extending feature extends at least in part.

Abstract: A method and system for collecting meteorological data. A plurality of vehicles travel on roads in a geographic region. Each of the vehicles includes sensor equipment that senses at least one meteorological condition. The sensor equipment may be used to support other vehicle systems, such as vehicle safety systems or a vehicle navigation system. Each of the vehicles includes a program run on a computing device in the vehicle that prepares messages containing data indicative of the one or more meteorological conditions sensed by the sensor equipment. The messages are sent wirelessly from the vehicle to a meteorological data collection service that collects the data and uses the data for weather modeling or forecasting.

Abstract: A method for calculating a distance between a first point and a second point using linear interpolation is provided. The first point and the second point are located between a first latitude and a second latitude. An interpolated prime vertical radius of curvature value for a point between the first point and the second point is calculated based on a first prime vertical radius of curvature value for the first latitude and a second prime vertical radius of curvature value for the second latitude. An interpolated meridian radius of curvature value for the point between the first point and the second point is calculated based on a first meridian radius of curvature value for the first latitude and a second meridian radius of curvature value for the second latitude. An interpolated cosine value for the point between the first point and the second point is calculated based on a value representing a cosine of the first latitude and a value representing a cosine of the second latitude.

Abstract: A geographic database for use with a navigation application program that provides navigation features to an end-user. The geographic database includes a plurality of data records of a first type and a plurality of data records of a second type. The plurality of records of the first type are organized into a plurality of parcels, each of which includes a plurality of data records of the first type and the plurality of records of the second type are organized into a plurality of parcels, each of which includes a plurality of data records of the second type. The parcels of data records of the first type are interleaved with the parcels of data records of the second type. This interleaving enables navigation functions that use these different types to access these different types more quickly and efficiently, thereby enhancing navigation system performance.
