It's the main basis of calculating node flow, and has great influence on the accuracy of the network model and the reliability of the optimization scheduling. Because of the complexity of the variation of water in the urban water supply network simulation modeling process, put...
The carbon from xylene pyrolysis infiltrated into coke to enhance the CSR (coke strength after reaction) of coke to improve coke performance for energy-saving and emission-reducing. Taking aim at the CSR, the optimum infiltration conditions of the carbon of xylene pyrolysis were researched through chemical vapor infiltration using response surface methodology. Optimum results showed that the value...
Slope engineering is a typical problem of mountain highway and ecological slope protection is a widely used engineering technology in current construction. For the best choice of ecological slope protection in mountain highway construction, multi-level evaluation indexes system on ecological bank is firstly established according to multi-dimension evaluation principles and decision model is then figured...

In this study, we try to present an approach to greenway analysis and evaluation of the equipment system and the recreational suitability of the Licheng section of the Guangzhou Zengcheng Greenway. This study aims to improve the quality of design and to make the greenway...
Based on the characteristics of urban water supply system, the urban pipe network security assessment system was established, and then AHP method combined with fuzzy evaluation was used to carry out a comprehensive security assessment for the leakage of the urban pipe network. By calculating a real case and analyzing various leakage causes and their impact, the assessment model was verified reasonable.
According to the ecological security system being fuzzy, we make use of AHP to determine the weight of evaluation index on the basis of the relevant historical data and unique geographical climate characteristics of the petrochemical area. And set up the ecological safety evaluation system with the MATLAB and GUI
The purpose of this paper is to track the speed and output power of wind turbine in Simulink/Matlab environment. By adjusting the speed of variable speed wind turbine,the simulation model can keep running at optimum tip speed ratio, and then achieve maximum power transfer. In this process, this paper uses PI controller to track and control the speed and output power of wind turbine. Simulation results...
This paper provides an idea that using fly ash discharged from power plants as sulfur sorbent for desulfurization. This method can not only economize large expenses of sulfur sorbents and simplify desulfurization devices, but also solve the pollution of fly ash discharging. The desulfurization regulations with different proportions and concentrations of the compound sulfur sorbents (CaCO3 and fly...
To examine the toxicity of residue of succinylcholine chloride (SCC), the residue of SCC from experimental mice killed by 2ml 10 g/L injection of SCC was determined by the method of H-NMR and the residue toxicity was tested. 60 mice divided into six groups, were given with SCC, 625, 62.5, 6.25, 0.625 mg/kg, administered orally by the dose of 50mg; The control group were fed with the same amount dose...
The Grid task scheduling is the process of the tasks that one user submit to the grid environment are distributed to each node of the resources according to some rules. Reasonable task scheduling algorithm can greatly improve the effective utilization of grid system. In the grid environment, Users want their task as quickly as possible to get accomplished, but the gird environment is hoping to take...

Establishing correspondence between moving objects is a key problem in multi-camera surveillance, and Field of View (FOV) line is an efficient tool to resolve the consistency in labeling objects. In this paper, we get the camera field of view lines by using Scale-Invariant Features Transform (SIFT) algorithm and homograph, without knowing the camera calibration information. First, by using SIFT algorithm,...
A method of cloth simulation was researched in this paper. The algorithm based on space decomposition method to locate at the intersection of area, further use hash table data structure to save the geometry of the object information and update the hash table in the method of Parallel Algorithm. It can find not only the colliding elementary geometry entity pairs but also the precise colliding points...

In this paper, we survey recent research in VANETs emergency messages dissemination. We structure the survey into two broad categories: IEEE 802.11p/WAVE and MAC protocols, and routing protocols, and describe key ideas of representative technologies in each category. In addition, we consider mobility models and simulation scenarios that are crucial for emergency messages dissemination in VANET. We...
The traveling state of submarine in water includes deep in water and near water-surface. Compared with the deep water submerged body, the flow field around a moving submerged body near the free surface is more complex, submerged body will suffer from wave-resistance. Uses ANSYS-ICEM software to build submarine model and computes it with CFX software. The resistance and wave pattern of a submarine...
