Social multimedia sharing and hosting websites, such as Flickr and Facebook, contain billions of user-submitted images. Popular Internet commerce websites such as Amazon.com are also furnished with tremendous amounts of product-related images. In addition, images in such social networks are also accompanied by annotations, comments, and other information, thus forming heterogeneous image-rich information...
Deep understanding of pH variation during biological nitrogen removal is critical for ensuring the effective operation of nitrification/denitrification or nitritation/denitritation processes on a real-time basis. Two tank-type glass vessels, with a 6 L working volume for each, were used as sequencing batch reactors (SBRs) to investigate variation of pH in biological nitrogen removal process (nitritation,...
As the main resources for the development of universities, job performance of College teachers directly affect the development level of universities teaching and research, but their influencing factors of college teacher performance are numerous, certain, uncertain and fuzzy. Therefore, it is particularly important to establish a scientific and reasonable comprehensive evaluation model of college...
Traditional generation dispatch takes minimum of generation cost as the aim, whereas environmental economic dispatch (EED) would not only consider economic operation, but also consider environmental protection. From the point view of coordinated optimization, this paper discusses EED in interconnection areas. Purchase costs and pollution emissions are simultaneously adopted as objective functions...
Pricing decision of one leader and one follower ecological industry chain under incomplete information was studied. Game model include Individual rationality constraint and Incentive compatibility constraint were constructed by revelation principle, price expression was obtained by iterated computation. Effects of parameters change to profit were analyzed, numeral computation was given at last.
This paper presents a detailed analytical solution for a mathematical model of Emulsion Liquid Membrane (ELM) extracting hazard metal from waste water. By solving the resulting simultaneous partial differential equations using the Laplace transform method, we obtain formulas for solute (hazard metal) concentration in external phase (waste water) versus time, solute concentration profile inside the...
The integrated principle of SINS/CNS/SMNS is investigated, and a federated information fusion method for the integrated navigation system is founded. On account of primary navigation errors of SINS aroused by the errors of initial position, attitude alignment and inertia sensors, a novel independent navigation scheme of using CNS and SMNS to update SINS is proposed. When the cruise missile had been...
LPI is not efficient in time and memory which makes it difficult to be applied to very large data set. We propose a optimal algorithm called FLPI. FLPI decomposes the LPI problem as a graph embedding problem plus a regularized least squares problem. Such modification avoids eigen decomposition of dense matrices and can significantly reduce both time and memory cost in computation. Moreover, with a...
