20130066855 | NESTED COMPLEX SEQUENCE PATTERN QUERIES OVER EVENT STREAMS - A method of evaluating nested complex sequence pattern queries includes obtaining events from an event stream and evaluating the events within a first window using an outer query to produce outer partial results. The method also includes determining a more stringent window constraint, the more stringent window constraint comprising a subset of the window constraint corresponding to events that produces the outer partial results and passing the more stringent window constraint to an inner query nested within the outer query. A complex event processing system is also provided. | 03-14-2013 |

20130226972 | METHODS AND SYSTEMS FOR PROCESSING DATA ARRAYS USING BLOOM FILTERS - The present disclosure relates to computing techniques. Data arrays are processed using Bloom filters to determine aggregate count, maximum, and minimum. These methods can be used on different types of data, including data groups, partial groups, data cubes, hypercubes, and others. | 08-29-2013 |
20130289864 | IDENTIFYING IMPACT OF A TRAFFIC INCIDENT ON A ROAD NETWORK - A method and system for identifying impact of a traffic incident on a road network, wherein the impact may be measured in terms of a spatial-temporal-impact region, in terms of incident duration from the time the incident is reported to the time at which the affected road network returns to recurrent flow conditions, and in terms of a cumulative time delay of all affected drivers. | 10-31-2013 |
20130289865 | PREDICTING IMPACT OF A TRAFFIC INCIDENT ON A ROAD NETWORK - A method and system for predicting impact of traffic incidents on a road network by using a classification scheme to identify a known impact classes associated with captured traffic data. | 10-31-2013 |
20130290350 | Similarity Search Initialization - A similarity search initialization system includes a leaf selector to select a leaf of a suffix tree generated from a target string representing a target sequence. The selected leaf is associated with a prefix in the suffix tree having a longest match to a suffix of a query string representing a query. The system further includes a distance module to determine a distance between the query and a subsequence of the target sequence represented by a candidate substring of the target string. The candidate substring includes the prefix associated with the selected leaf. The determined distance is to provide an initial upper bound in a similarity search of the target sequence using the query. | 10-31-2013 |
20140039782 | DETERMINING A SPATIOTEMPORAL IMPACT OF A PLANNED EVENT ON TRAFFIC - Systems and methods are provided for determining an impact of a planned event. Traffic flow velocity is measured at each of a plurality of traffic sensors over a period of time before the planned event, with each traffic sensor having an associated geographical location. A plurality of measured traffic flow velocities for each traffic sensor are stored on a non-transitory computer readable medium. A traffic flow velocity at each traffic sensor is measured at each of a plurality of representative times within a defined time period including a known start time and an expected end time of the event. A threshold velocity is calculated from the stored traffic flow velocities for each traffic sensor corresponding to each representative time. For each representative time, a set of traffic sensors is determined at which the measured traffic flow velocity during the defined time period is less than the threshold velocity. | 02-06-2014 |
