Exploratory data analysis, also known as data mining or knowledge discovery from databases, is typically based on the optimisation of a specific function of a dataset. Such optimisation is often performed with gradient descent or variations thereof. In this book, we first lay the groundwork by reviewing some standard clustering algorithms and projection algorithms before presenting various non-standard...
This paper introduces the design and implementation of HTTP proxy server based on real-time link. The real-time link packages UPLink and PSLink into a link. The UPLink is the link between user and proxy server, and PSLink is the link between proxy server, and target server. These two links exist and close together, and it can solve the problem of link's closed incompletion. This approach can reduce...
In this paper, one simple binaphthyl-bridged salicylidene Schiff base (2,2'-bis(3,5-dichloro-2-hydroxybenzylideneamino)-1,1'-binaphthyl (BCHB)) was successfully modified into the channel of mesoporous molecular sieve SBA-15. Detailed characterizations demonstrated that the inner channel of SBA-15 was firstly functionalized with 3-aminapropyltriethoxysilane, then the functional molecule BCHB was anchored...
Partial differential equation (PDE) and Markov random field are two kinds of texture preserving regularized image denoising models. In this paper, the equivalence of them is proved: PDE can be derived to have the form of Markov model. Total variation (TV) is a kind of PDE, the adjacent domain of it is first order. Based on Markov theory, the adjacent domain of TV is enlarged to second order and it...
A new method to estimate the induction motor stator and rotor resistance (Rs and Rr) and temperature (Ts and Tr) was proposed in this paper. Two signals with proper frequencies that yield high sensitivities of terminal measurement to Rs and Rr at a given rotor speed are injected to the induction machine to estimate Rs and Rr. The estimated Rs and Rr are then used to estimate Ts and Tr respectively,...
