Logarithm-transform piecewise linearization method for the optimization of fasoline blending processes
《Chinese Journal of Chemical Engineering》2018年第8期1684-1691,共8页Yu Li Tong Qiu 
Supported by the National Basic Research Program of China(2012CB720500);the National Natural Science Foundation of China(U1462206)
Gasoline blending is a key process in a petroleum refinery, as it can yield 60%–70% of a typical refinery's total revenue. This process not only exhibits non-convex nonlinear blending behavior due to the complicated ...

A Temporally Piecewise Adaptive Scaled Boundary Finite Element Method for Solving the Fuzzy Uncertain Viscoelastic Problems被引量：1
《Acta Mechanica Solida Sinica》2018年第4期459-469,共11页Qiwen Xue Jing Wang Yiqian He Haitian Yang Xiuyun Du 
The numerical solutions for uncertain viscoelastic problems have important theo- retical and practical significance. The paper develops a new approach by combining the scaled boundary finite element method （SBFEM） a...

An efficient algorithm to compute transient pressure responses of slanted wells with arbitrary inclination in reservoirs被引量：3
《Petroleum Science》2012年第2期212-222,共11页Wang Haitao Zhang Liehui Guo Jingjing Liu Qiguo He Xinming 
financial support from the special fund of China’s central government for the development of local colleges and universities―the project of national first-level discipline in Oil and Gas Engineering, the National Science Fund for Distinguished Young Scholars of China (Grant No. 51125019);the National Program on Key fundamental Research Project (973 Program, Grant No. 2011CB201005)
Compared with vertical and horizontal wells, the solution and computation of transient pressure responses of slanted wells are more complex. Vertical and horizontal wells are both simplified cases of slanted wells at ...

Ruin Probabilities for a Risk Model with Two Classes of Claims被引量：1
《Acta Mathematica Sinica,English Series》2010年第9期1749-1760,共12页Tong Ling LV Jun Yi GUO Xin ZHANG 
Supported by the National Natural Science Foundation of China (Grant No. 10871102);National Basic Research Program of China (973 Program) 2007CB814905
In this paper we consider a risk model with two kinds of claims, whose claims number processes are Poisson process and ordinary renewal process respectively. For this model, the surplus process is not Markovian, howev...

Inferring playback rate and rate resets of P2P video streaming transmissions by piecewise line envelope approximation
《The Journal of China Universities of Posts and Telecommunications》2009年第2期58-62,79,共6页LI Chun-xi CHEN Chang-jia School of Electronics and Information Engineering,Beijing Jiaotong University,Beijing 100044,China 
supported by the National Natural Science Foundation of China(60672069,60772043);the National Basic Research Program of China(2007CB307101)
Conventionally, P2P video is regarded as CBR traffic. However, our measurements have shown that the rate reset cannot be neglected in a practical IPTV system because each rate reset often leads to performance degradat...
