Different kinds of features hold some distinct merits, making them complementary to each other. Inspired by this idea an index level multiple feature fusion scheme via similarity matrix pooling is proposed in this paper. We first compute the similarity matrix of each index, and then a novel scheme is used to pool on these similarity matrices for updating the original indices. Compared with the existing...
The expanding social network and multimedia technologies encourage more and more people to store and transmit information in visual format, such as image and video. However, the cost of this convenience brings about a shock to traditional video severs and exposes them under the risk of overloading. In the huge volume of online videos, there are a large amount of near-duplicate videos (NDVs). Although...
Day-Ahead Unit Commitment is a typical business process of regional transmission organizations (RTO) and some vertically integrated utilities to ensure enough generation capacity is committed day-ahead to meet the load for the next day. In many cases, transmission constraints are required to be taken into consideration under the framework of security-constrained unit commitment (SCUC). Transmission...
Incorporating line switching as a part of security enhancement could more effectively alleviate overloads of branch equipment in system operations. In market operations, co-optimizing transmission topology and generation dispatch could be a viable way to improve economic efficiency. This paper discusses the integration of line switching in energy and market management systems (EMS/MMS) for control...
Many real applications, such as network traffic monitoring, intrusion detection, satellite remote sensing, and electronic business, generate data in the form of a stream arriving continuously at high speed. Clustering is an important data analysis tool for knowledge discovery. Compared with traditional clustering algorithms, clustering stream data is an important and challenging problem which has...
Red mud foamed block is prepared using waste of aluminum oxide production—red mud, soft burning magnesium powder (MgO), bischofite (MgCl2·6H2O) and various addition agents. The influence of each factor on strength and density of red mud foamed block is analyzed by orthogonal experiment in this paper. The best ratio is obtained as follows: red mud 30%, MgO 40%, F-3 high efficiency composite foaming...
With the development of technology, calculated amount especially in seismic data processing is increasing in virtual computing environment and the data size is astonishing. In this paper, based on the seismic data and the influence factors during the calculation, we present a suitable data partitioning strategy-the PGA (Pretreatment Genetic Algorithm) algorithm. The scheduling problem in virtual computing...
Under Midwest ISO's real-time market, energy and ancillary service products are co-optimized. It is very important for operators to have an indication of where the system stands and take proper action if needed. In this paper, both analytic and numerical methods are presented to evaluate the available room to meet power balance and reserve requirements. It essentially presents indexes on how far away...
E-business is the more and more important channel for travel & hotel booking and payment especially in China for the fast development of cyber industry and a rapidly increases number of netizens in the country. The paper selects top 20 tourism e-business websites in China. Then evaluate the effectiveness of the websites with the purpose-value framework of evaluation on the content delivery performance...
This paper describes one valid framework of integrating intensity discontinuity and edge continuity for image Straight-line Extraction. First, multiple "edge contours" are traced out from digital image by means of classic LOG algorithm and contour tracing principle. In this step, Zero-Cross points are detected without implementing traditional "edge labeling" procedure and thus,...
Rapid urbanization and industrialization have been going with urban growth and pattern evolvement in relatively developed regions of China's coast. This paper presents an integrated study on the urban growth patterns of the area around Taihu Lake, China, by using Geographical Information Systems (GIS) and remote sensing. High-resolution Landsat TM data in 1985, 1995, 2000 and 2005, and socioeconomic...
