Abstract: According to one aspect, routing of an autonomous or semi-autonomous vehicle may be based at least in part upon the availability of particular geographical areas through which the vehicle may be routed. A geographical area may be defined, based on constraints such as road conditions, lane features, operational constraints, etc., such that at least one routing path between each of one or more sources and one or more destinations within the geographical area may be traversed by a vehicle. Constraints may be temporary and may be accounted for substantially in real-time when defining and/or updating a geographical area within which a vehicle is to operate. In some instances, an inclusion constraint can be defined based on a frequency of use of a given routing path associated with one or more points of interest for a geographical area. Accounting for constraints enables autonomous vehicles to be deployed safely and efficiently.

Abstract: A voltage stability prediction system is configured to predict voltage stability of a power system under a contingency. The voltage stability prediction system in this regard may execute model-based contingency analysis using a model of the power system to predict, as of a first time, voltage stability of the power system post-contingency. The voltage stability prediction system also obtains, from phasor measurement units (PMUs) in the power system, synchrophasor measurements that indicate, as of a second time later than the first time, phasors in the power system pre-contingency. Further, based on the model-based contingency analysis and the synchrophasor measurements, the voltage stability prediction system predicts, as of the second time, voltage stability of the power system post-contingency.

Abstract: The present disclosure provides a method and system for generating a QR code by receiving an inputted document; pre-processing the inputted document so as to obtain desired content; encrypting the desired content; and generating one or more QR codes based on the encrypted desired content.

Abstract: Embodiments of the present invention relate to a method and system for analyzing user behaviors. The method comprises: generating action sequences according to action identifications in user behavior records; determining a common subsequence based on the action sequences, the common subsequence being a subsequence that is common to at least two action sequences among the action sequences; and constructing a sequence pattern based on the common subsequence.

Abstract: A method and system for recording or selecting visual bookmarks in the process of playing a multimedia data are disclosed, wherein users can play the multimedia data at one of the mark in point. The visual bookmarks are represented by playing the sounds or the pictures at the mark in point in the multimedia data. Thus, users can directly understand where the mark in point of each visual bookmark is in the multimedia data.
