Adaptive B-snake for planar curve approximation

作者：CHENG; Si-yuan; ZHANG; Xiang-wei; HUANG; Man-hui 刊期：2005年第04期

An adaptive B-spline active contour model for planar curve approximation is proposed. Starting with an initial B-spline curve, the finite element method is adopted to make the active B-spline curve converge towards the target curve without the need of data points parameterization. A strategy of automatic control poin...

Allocation of fixed transmission cost based on power flow tracing algorithm

作者：ZHANG; Qian; YU; Ji-hui 刊期：2005年第04期

In the electricity market, charging based on the traditional spot electricity price often results in the payment imbalance of electric network, and goes against the development of the power system. So, it is necessary to modify the spot price. The key of the modification lies in how to calculate the fixed unit transm...

Flame radiant image numeralization for pulverized coal combustion in BF raceway

作者：WEN; Liang-ying; OU; Yang-qi; BAI; Chen-guang; WANG; Hua 刊期：2005年第04期

In order to establish correlativity between pulverized coal combustion in a blast furnace raceway and its radiant image, we investigated the relationships between two dimensional radiant images and three dimensional radiant energy in a blast furnace raceway, focusing on the correlativity of the numerical simulation o...

Sustainable urbanization：energy and environment in the Chongqing Municipality,China

作者：LI; Bai-zhan; LIU; Meng; YAO; Run-ming; Koen; Steermers 刊期：2005年第04期

Chongqing is the largest municipality under the Chinese Central Government (MCG) in terms of administrative area and population and is now the most important economic and cultural center of the upper Yangtze River and Three Gorges area. The Three Gorges Dam project, one of the largest world infrastructure projects, c...

Characteristics of integrated biological aerated filter in municipal wastewater treatment

作者：HE; Qiang; ZHANG; Yu-ping; XU; Jian-bin 刊期：2005年第04期

In this paper, the characteristics of integrated biological aerated filter (IBAF) applied to municipal wastewater treatment were studied in a pilot scale experiment. The experimental results showed that IBAF has high efficiencies in removing organic pollutants, such as CODCr and SS, in municipal wastewater. The remov...

Applications of artificial intelligence technology to wastewater treatment fields in China

作者：QING; Xiao-xia; WANG; Bo; MENG; De-tao 刊期：2005年第04期

Current applications of artificial intelligence technology to wastewater treatment in China are summarized. Wastewater treatment plants use expert system mainly in the operation decision-making and fault diagnosis of system operation, use artificial neuron network for system modeling, water quality forecast and soft ...

Effects of doping Fe and Al on microstructure and electrochemical characteristics of Mg-based hydrogen storage alloys

作者：XIE; Zhao-ming; PAN; Fu-sheng; FU; An-qing; ZHANG; Sheng-tao; DING; Pei-dao 刊期：2005年第04期

The Mg-based hydrogen storage alloys Mg2Ni, Mg2Ni0.7Fe0.3 and Mg1.7Al0.3Ni were successfully synthesized by a two-step process (sintering and ball milling). The crystal structure and microstructure were examined by X-ray diffraction, Scanning Electron Microscope and Malvern particle size analyzer. New phase appears i...

Synthesis of thiadiazole-based Schiff base metal complexes and their inhibition rate to superoxide anion free radical

作者：WANG; Jian-hua; LV; Zheng-jian; XU; Shi-rong 刊期：2005年第04期

A new series of Schiff base ligands were synthesized by the condensation of 2-amino-5-mercaptan-1,3,4-thiadiazole and salicylaldehyde or 2,4-dihydroxybenzaldehyde and their derivatives with choroacetic acid, and further reaction with corresponding metal acetate to form metal complexes. The compositions and structures...

Ant-cycle based on Metropolis rules for the traveling salesman problem

作者：Gong; Qu; He; Xian-yang 刊期：2005年第04期

In this paper, recent developments of some heuristic algorithms were discussed. The focus was laid on the improvements of ant-cycle (AC) algorithm based on the analysis of the performances of simulated annealing (SA) and AC for the traveling salesman problem (TSP). The Metropolis rules in SA were applied to AC and tu...

作者：LI; Chun-hong; LI; Jiang-tao 刊期：2005年第04期

This present paper investigates the complex oscillation theory of certain high non-homogeneous linear differential equations and obtains a series of new results.

EVA based model to estimate the Chinese listed company＇s intrinsic value

作者：RAN; Mao-sheng; ZHONG; Tao; HU; Guo-peng 刊期：2005年第04期

This article is based on traditionally intrinsic value assessment model. We employed the assumption on the differences in future increase rates of companies, taking into account of the expected Economic Value Added (EVA) discount and the capital investment, to establish a high increase model, a two-stage EVA discount...

Quantum entropies of electromagnetic and gravitational fields on Taub-NUT black hole background

作者：LIU; Xiao-ying; XIA; Shi-fa; LI; Fang-yu 刊期：2005年第04期

The main characteristics and Petrov type of Taub-NUT spacetime are studied, and the quantum entropy of Taub-NUT black hole due to electromagnetic and gravitational fields is calculated via brick-wall model. It is shown that the quantum entropy has both the linearly and the logarithmically divergent terms. For electro...
