Coke Index Analysis based on Principal Component Analysis and Decision Tree Mining Guo Hongweia, Su Buxin, Chang Jian, Zhang Jianliang, Cao Weichao School of Metallurgical and Ecological Engineering, University of Science and Technology Beijing, Beijing, China aghwvip@gmail.com Keywords: Blast Furnace; Coke; principal component analysis; decision tree; data mining Abstract: Current analysis in the relations between blast furnace production index and coke index is still using the traditional statistical analysis method，but it involves too many coke quality evaluation indexes and there are some overlap between the indexes.
The materials of blast furnace production mainly include ore, coke and coal, in which the coke quality index have the biggest influence on the blast furnace production index.

With the advent of the knowledge economy and the rapid development of information technology era, people's demand for the living environment has been far more than mere material comfort.
In the construction of ecological Residential district, we want to reasonable use environmentally friendly technologies and materials, make full use of clean energy and energy resources, plant cell with plants, landscape design and water circulation water treatment effective ecological treatment creating conducive to stability and harmony of natural ecosystems, but also help people health natural environment [1].
To comply with the principle of economy, it is necessary to properly control the garden landscape design in an area, selecting the ideal garden materials, reduce or do not take advantage of the large fountains and lawns, clever design on the original terrain, good use by the King, to reduce the cost of housing residential landscape design.

The dispersion characteristic of metal materials makes the traditional FDTD difference scheme inapplicable, so in the nano optical simulation, choosing proper dispersion model of metal materials will be the important process.
The approximate model can be applied to study the optical properties of metal materials, but it has lower precision.
In this paper, adopting gold as the metal materials, and fitting the dielectric constant for visible light and near-infrared band by modifying Drude model, the dispersion equation of the modifying Drude model: (1) Where, is plasma frequency, G is damping coefficient, the plasma frequency and damping coefficient show the attenuation characteristics of the plasma materials.
The structure, size and materials of the antenna are changed for pursuing bigger field enhancement.

Greenhouse Effect Reduction Through Sustainable Magnesium Oxide Eco-cement Products Wu Yaoa, Yukun Yangb, Mengxue Wuc Key laboratory of Advanced Civil Engineering Materials (Tongji University), MOE, Shanghai 201804, China ayaowuk@tongji.edu.cn, byangyukuntju@163.com, cwmx_129@163.com Key Words: Eco-cement, CO2 absorption ability, mechanical performance Abstract.
In the process of Portland cement production, there is significant carbon dioxide emission, including the release of carbon dioxide from the conversion of the raw materials, such as limestone, also significant is the fuel combustion to heat the raw materials to 1450°C during the clinkering process.
By incorporating of fly ash into the eco-cement, an energy saving and environmentally friendly material can be formed.

Calculation Model. a.Establishment of finite element model.Hydraulic Blasting simulation adopted the open cylindrical structures, plain concrete as materials, with 0.25m inner diameter, 0.1m wall thickness and 0.5m height.
The model consisted of explosives, water, concrete structures and air, the four kinds of materials.
Explosive, water and air, the three kinds of materials adopted Eulerian grid model, using multiple substances ALE algorithm for its unit; concrete adopted the Gulag Lang mesh to establish model.

Introduction Silicon Carbide (SiC), with its excellent intrinsic properties, is a suitable material for hightemperature, high-power and high frequency devices [1,2].
Despite the existence of native oxide (SiO2), there is a great interest in the investigation for alternative insulating materials on SiC.
Among the alternative gate dielectrics, Al2O3 is one of the most attractive materials for replacing SiO2 gate insulators, exhibiting a large dielectric constant (ε ~ 10), a large band gap (~ 9 eV), a good thermal stability and the highest conduction and valence band offsets, ∆Ec = 1.7 eV and ∆Ev =1.2 eV for 4H-SiC, compared to ZrO2 or HfO2 [4,5].
