This paper proposes a novel contribution factor (CF) approach to predict diversified daily peak load of low voltage (LV) substations. The CF for each LV template developed in part I of the paper is determined by a novel method—clusterwise weighted constrained regression (CWCR). It takes into account the contribution from different customer classes to substation peaks, respecting the natural difference...
In a scientific research network, to determine the influence of an academic research, a key is to build and evaluate properties of its cited references or co-author networks. To analyze 18,000 lines of original data from Problem C given in 2014 MCM/ICM (Mathematical Contest In Modeling /Interdisciplinary Contest In Modeling), the Pajek software was used with obtaining a result that correlations among...
According to the author's bilingual teaching practice on" Industrial Design History", four main problems were proposed, i.e., how to choose proper teaching pattern, how to master main knowledge points, how to communicate with students effectively and how to use multi-media teaching method.
The importance of industrial design in improving the innovative capacity of our country is well-known to all. In fact, design is part of the innovative industry and industrial design plays a very significant role in ??created in China?? from the point of economy and culture.
Content-based image retrieval (CBIR) is an effective approach for obtaining desired image, however, due to the semantic gap between low-level visual features and high-level concept of image, CBIR system of state-of-the-art always can't achieve satisfying retrieval performance. In this paper, we propose a novel CBIR system framework. In order to bridge the semantic gap, the mechanism of relevance feedback...
In deep web, a significant amount of information can only be accessed through query interface of a back-end database, however, general search engine can not interact with the query interface, resulting in the myriad hidden and unvisible information can not be accessed. Therefore, this paper proposes a novel method of filling forms of deep web entries by importing ontology technique. Firstly, construct...
In this paper, a novel sliding mode observer is presented for achieving the position sensorless vector control based on estimating the rotor position of permanent magnet synchronous machines. Compared to conventional sliding mode observer (SMO), the proposed observer based on sliding mode observer and phase-locked loop (PLL) can effectively reduce the influence of the sliding mode chattering and improve...
Video annotation is very important for video management, such as video retrieval. Despite continuous efforts in inventing new annotation algorithms, the annotation performance is usually unsatisfactory, and the annotation vocabulary is still limited due to the use of a small scale training set. In this paper, a novel video annotation framework based on the video object is presented, named object-based...
The advance of image capture device and the popularity of the Internet have made the World Wide Web the biggest and most diverse repository of images. How to retrieve images fast and accurately from the WWW has become an urgent problem to be solved. Although many commercial Web image search engine has come forth, the precision is not satisfying for the reason that the text in the pages which they...
In load forecasting of a bulk power system, the geographical scope of forecasting region is large, the main electrical load effecting factors in sub districts are different greatly. So it is very significance to establish different load forecasting model according to self-feature of each sub district of a large area, by which the forecasting load is closer to the fact load than establishing one model...
