Aiming at the structure feature of plagiarized source code, this paper proposes a kind of visual positioning recognition method based on the function domain mode of source code. According to the basic structure feature of source code, function domain is taken as the key point of visual recognition. In this method, the index of each function domain is recorded at first. Then it applies string matching...
Hunan is a major agricultural province in China. This paper analyses the international competitiveness of Hunan agriculture from three levels. Firstly, we evaluate its competitiveness in achievement by using indexes of MS, RCA and TC, and find Hunan agriculture has certain advantage, but it shows a downward tendency. Next, Hunan agricultural competitiveness in strength is analyzed from price and quality,...
This article proposes that when aviation product receives laboratory reliability verification test, the selection of statistical plans is undertaken according to the product features. With considering the effect of selecting statistical plans according to aviation product features, analysis and related suggestion are given when performing reliability verification test on the aviation product in lab.
BM25 is a well known ranking method to measure the relevance of the matching documents to a query.BM25 ranking functions can be used in recommendation when the query is transferred to represent userspsila interest. However, in this scenario,terms in the query need to be handled differently because they may come from sources that users have different levels of interests in. For example, some terms...
XPath has been widely used as a query language for selecting nodes from XML documents. Efficient XPath evaluation is thus a core building block in XML query processors. In the paper, we first introduce a compact structural summary index for XML data and then propose an efficient XPath evaluation algorithm based on this index. Our algorithm takes full advantage of the structural summary to prune a...
It is an essential operation in XML queries to determine the structural relationship between two arbitrary nodes. The numbering scheme is designed to label the XML nodes so that the structural relationships between nodes can be easily determined by comparing their labels without accessing the original XML file. This paper presents a novel XML tree numbering scheme, called BFN, which takes advantage...
Paper studied the method of designing BSC in newspaper by knowledge management. In virtue of the knowledge management, it makes closer relation between enterprise strategy and evaluation indicators, draws a frame of evaluation from perspective of BSC, and selects the indicators from finance, readers, interior flow and innovation. In the end a case is given.
Power-efficient scheduling and resource allocation are critical tasks for wireless sensor networks as well as commercial and tactical radios relying on IEEE access standards for power-limited communications. Tailored for such applications, this paper formulates and solves analytically novel convex optimization problems offering globally optimal user scheduling, as well as rate and power allocation...
