The present invention discloses a license plate recognition system by utilizing spatial-temporal search-space reduction and method thereof. The license plate recognition system can selects a pixel with character edge feature from the inputted image and a plurality of candidate regions from the image; and detect if the candidate region of the inputted image has been appeared in a preceding image. Then the recognition system in the present invention separates the candidate region into a plurality of blocks, calculates the repeated block based on a current image and a preceding image, and determines whether the candidate region is repeated according to the repeated block. Thus, by discarding the repeated regions, the license plate recognition system in the present invention can avoid redundant calculation and improve the efficiency and performance for recognition of real plate character in the image.

The invention discloses a wavelet transform and time search strategy based double-end traveling wave fault location method for hybrid power transmission line. The method comprises the following stepsof 1) determining an electrical topological structure of the hybrid power transmission line MN; 2) acquiring the motion time of traveling waves on a section line according to the length and motion wave speed of each section line; 3) according to fault traveling wave information acquired by traveling wave distance measuring devices at the two ends of the line, adopting wavelet transform to detect and identify the moment when the fault traveling wave moves to each bus measuring end for the first time so as to obtain a time difference when the traveling wave arrives at the two ends of the bus, and calculating t1 an t2 according to formulas by combining movement time of the fault traveling wave on the whole power transmission line; and 4) starts comparing from the end M of the bus, judging that the fault position is behind the xj1 section when t1>deltat1, and judging that the fault position is on the xd1 section when deltat1<t1<deltat1+deltat2, thus calculating the fault position. The method can be used to identify the initial traveling wave of a fault more accurately, and effectively solve the problem in fault distance measurement of the cable and overhead line hybrid power transmission line of the power system.

A system and a method for conducting spatio-temporal search using crowd source based real-time database are provided. The method may include: receiving from an inquiring user a combination of user related data (URD) related to at least one real time event, comprising at least one of: a temporal data, a spatial data and a contextual filter; generating a tempo-spatial contextual query based on the received URD; storing tempo-spatial contextual (TSC) data received from a crowd of users over a computerized network wherein said TSC is indicative of real time events; applying said query to said real time database for retrieving TSC data relevant to said query, wherein said search engine utilizes real time ranking from said crowd of users in applying the query; and presenting the relevant TSC data to the inquiring user.

An image voice play apparatus for playing an AVI file includes: a control portion that when an instruction for a time search is issued, estimates the “number of voice chunks in one movi chunk,” determines in which AVI chunk a voice chunk for the time search is situated, reads an idx1 chunk in the “determined AVI chunk” without reading an idx1 chunk in an AVI chunk other than the “determined chunk,” and determines a play start position that corresponds to the time search.

The invention provides a network resource configuration method and device, computer equipment and a readable storage medium. The method comprises: obtaining a network resource optimal configuration model; and according to the transmission task information and the resource configuration strategy, performing resource allocation, converting the network resource optimal configuration model into a taskstability optimization model corresponding to network resource configuration, solving the task stability optimization model to obtain network resource configuration information of continuous task transmission, and configuring network resources according to the network resource configuration information. According to the method, task types and network state time-varying characteristics can be considered; and, aiming at the heterogeneous communication network, a process-oriented continuous task network resource optimal configuration problem is converted into a time slot-oriented task stabilityoptimization problem, and the task stability optimization problem is solved to obtain network resource optimal configuration information to realize network resource optimal configuration, so that thetime search dimension and the resource search dimension are reduced, and the algorithm complexity is reduced.

A method, system and computer program product for assisting an expert to answer preexisting questions in a time efficient manner. The expert's data entry in a data entry system is detected by a unit, referred to herein as the “analyzer.” The analyzer searches a database or social media websites to identify questions that could possibly be answered using the expert's inputted data. Such questions may be identified using tag searching, keyword searching and/or natural language processing. The analyzer performs analytical analysis on these identified questions to assign a relevance factor to assess how relevant is the expert's inputted data in answering the question. For those questions whose relevance factor exceeds a threshold, those questions are presented to the expert in a list. In this manner, the expert does not have to spend time searching social media websites for applicable questions to answer.

The invention relates to a movie and television expression search method and device, a storage medium and computer equipment. The method comprises the steps of receiving a user search request; obtaining a search text corresponding to the user search request; performing word segmentation on the search text to obtain an entity text and/or a non-entity text, the entity text including a movie name anda figure name, and the non-entity text including verbs, adjectives and words representing emotions; obtaining expressions, matched with the entity text and/or the non-entity text, of the labels in the picture library as target expressions; obtaining the click rate, the storage time and the search relevancy of the target expression; and sorting the target expressions according to the click rate, the storage time and the search relevancy of the target expressions, and outputting the target expressions in a descending order. According to the technical scheme, the expressions are searched according to the entity labels, the non-entity labels and the document labels, and the searched expressions are comprehensively sorted according to the dimensions such as the search relevancy, the click rateand the time, so that the expression search result output to the user is more accurate.

The invention provides an event searching method and device, a computer readable medium and electronic equipment, and relates to the technical field of data processing. The method comprises the steps:obtaining a search theme of a target event, and determining a target user set according to the search theme; obtaining a comparison time interval of the target event, wherein the comparison time interval comprises at least two sub-intervals; obtaining a comparison index of the target event, and for each user identifier in the target user set, obtaining an index data set about the comparison indexgenerated in each sub-interval; and according to the index data set corresponding to each sub-interval, determining a comparison value about the comparison index corresponding to each user identifierin the target user set so as to complete search of the target event. According to the technical scheme, the time search efficiency can be effectively improved.
