A generation pricing method with capacity bidding
Journal of Shanghai University (English Edition) - Tập 5 - Trang 345-352 - 2001
Due to historic reasons China encounters some special difficulties in ESI (electricity system industry) restructuring. An easy and simple electricity value equivalent (es-EVE) method for day-ahead pool purchase pricing of China is therefore presented in this paper. The es-EVE method is different from two-part and one-part tariffs. It is more like the UK’s method in form, but revised for China with......
Emissions of volatile organic compounds and carbonyl compounds from residential coal combustion in China
Journal of Shanghai University (English Edition) - Tập 14 - Trang 79-82 - 2010
Emissions of volatile organic compounds (VOCs) and carbonyls from residential coal combustion of five coals with different maturities were studied in a simulated room. The coals were burned in form of honeycomb briquettes in a domestic coal stove, one of the most common fuel/stove combinations in China. Through a dilution system, VOCs and carbonyls samples were collected by canisters and silica-ge......
Upper bounds for ramsey numbers R(m ,n ,1) and R(m ,n, l, s) with parameter
Journal of Shanghai University (English Edition) - Tập 7 - Trang 46-48 - 2003
In the paper some new upper bounds with parameters were obtained for the classical Ramsey numbers R(m, n, l) and R (m, n ,l, s). By using the upper bounds, it was proved that 72(4,4,4)≤236.

A hybrid genetic-simulated annealing algorithm for optimization of hydraulic manifold blocks
Journal of Shanghai University (English Edition) - Tập 12 - Trang 261-267 - 2008
This paper establishes a mathematical model of multi-objective optimization with behavior constraints in solid space based on the problem of optimal design of hydraulic manifold blocks (HMB). Due to the limitation of its local search ability of genetic algorithm (GA) in solving a massive combinatorial optimization problem, simulated annealing (SA) is combined, the multi-parameter concatenated codi......
Joint power control based on service factor for code division multiple access system
Journal of Shanghai University (English Edition) - Tập 12 - Trang 414-418 - 2008
An important feature of the traffic in mobile networks is burstiness. Drawbacks of conventional power control algorithms for time division duplex (TDD)-code division multiple access (CDMA) systems are analyzed. A joint power control algorithm based on service factor is presented to address the TDD-CDMA mobile services in the burst mode according to the Markov modulated Bernoulli process. The joint......
A pfaffian formula of the generalized inverse function-valued fade approximant used in solving integral equations
Journal of Shanghai University (English Edition) - Tập 7 - Trang 318-321 - 2003
The generalized inverse function-valued Padé approximant was defined to solve the integral equations. However, it is difficult to compute the approximants by some high-order determinant formulas. In this paper, to simplify computation of the function-valued Padé approximants, an efficient Pfaffian formula for the determinants was extended from the matrix form to the function-valued form. As an imp......

Experiment study on solidification effect of sewer sludge
Journal of Shanghai University (English Edition) - Tập 12 - Trang 180-183 - 2008
Materials such as cement and composite active admixture were mixed in definite ratio to consolidate sewer sludge, which had been dried and smashed. Two kinds of solidified bodies were designed. A represented the solidified body which had not used any composite active admixture, and B represented the one which used composite active admixture as one of its compositions. The results show that the com......
