Abstract: A new diagnostic based on Doppler shift is designed to measure the power profile of a hydrogen or deuterium neutral beam on the magnetic confined fusion machines. The interference filters and multi-channel photon detector array (PDA) are the main components of this diagnosis. The multi-channel PDA measures the line integrated Doppler Ha signal emitted by the neutral beam at one section in two directions. The local intensity of neutral beam can be obtained with the tomography technique. Compared to the conventional calorimeter diagnoses, this diagnosis can provide the beam profile without blocking the injection of neutral beam.

Abstract: Dynamic behaviour of fast electron in lower hybrid current drive (LHCD) experiment is a crucial issue in the sense of enhancing plasma performance. A new hard x-ray diagnostic system on HT-7 allows the investigation of the lower hybrid wave dynamics. The behaviour of fast electron is studied in several kinds of LHCD experiments, including long pulse discharges, high performance discharges and counter-LHCD experiments.

Abstract: Decision on gradually reforesting and regrassing some of the dry land based on ARCGIS in Sichuan Province is discussed here,which is very important for the ecological restoration and sustainable development in Sichuan.Five steps are included.Firstly,the database platforms for making decisions are established including land use,soil erosion,DEM,slope,eco-environmental quality,normalization vegetation index(NDVI),precipitation,temperature,vegetation subregion,soil type,administrative district,waterbody buffer and residential area buffer which are created by using ARCGIS.All data are referenced to the same projection and coordination,and interpolated as grid data with a resolution of 100 m.Secondly,the dry land from landuse database is overlain with slope database,soil erosion database,NDVI database,eco-environmental quality database,waterbody buffer data and residential buffer data.Thirdly,the expert knowledge about reforesting and regrassing some of the dry land is collected,and the models for finding a suitable place for being returned back to forestland and grassland are formulated based on ARCGIS by using the knowledge.There are 724495 and 333085 ha of dry land to be gradually converted into forestland and grassland on the basis of the models,which respectively account for 9.3% and 4.3% of the dry land.Fourthly,the suitable place is overlain with precipitation layer and temperature layer to find out the place respectively suitable for trees and grass by the model that is formulated by using the knowledge of forest distribution and ARCGIS.In the first order,there are 702362 and 22133 ha to be respectively converted into forestland and grassland,or 96.9% and 3.1% of the suitable place for firstly being returned back to forestland and grassland.In the second order,there are 331357 and 1728 ha to be respectively converted into forestland and grassland,which respectively account for 99.5% and 0.5% of the suitable place for secondly being returned back to forestland and grassland.Finally,the distributions of the place suitable for trees and the place suitable for grass in administrative district,vegetation subregion and soil type region were obtained by using the overlay and spatial statistic analysis,which are of benefit to the selection of suitable tree and grass species for reforesting and regrassing.The research shows that with this the method considerable manpower,material and financial resources can be used sparingly.The result can not only be presented in table form,but also in graphic form,which is very useful for planning,executing,and managing the program of reforesting and regrassing some of the dry land in Sichuan province.

Abstract: 采用溶胶凝胶法, 在不同的退火温度下制备了不同的氧化钒薄膜. 利用扫描电子显微镜、X射线衍射仪、高阻仪、紫外-可见分光光度计和傅里叶红外光谱仪等, 对薄膜的形貌、晶态、电学和光学特性进行了分析. 结果表明, 溶胶凝胶法获取V2O5薄膜的最佳退火温度为430 ℃, 低于此温度不利于使有机溶剂充分分解, 高于此温度则V–O键发生裂解、形成更多的低价态氧化钒. 本文制备的氧化钒薄膜具有较高的电阻温度系数和光吸收率, 适合应用在非制冷红外探测器中. 本文揭示了溶胶凝胶法制备氧化钒薄膜的生长机理.

Stock Pattern Mining and Correspondence Analysis Based on Association Rules  [PDF]
Xingru Yue, Feng Shi
Journal of Data Analysis and Information Processing (JDAIP) , 2017, DOI: 10.4236/jdaip.2017.53006
Abstract: In this paper, association rules were applied to mining patterns in stock K-line trend. The pattern which ordinary investors interested in is defined as T-RG (Three-Red Guards). In the mining process, we take the K-line in A-share markets as objects. Through the analysis, investors can select the appropriate point of purchase and selling point. With the help of T-RG, investors can better improve the chance of short-term investment success in A-share markets. In order to explore and validate the T-RG, the main contents of this paper include the following aspects: putting forward a method that judge the validity of rules based on confidence-lift; proposing the meta rule that corresponds to the pattern of T-RG; developing a computer program to extract the T-RG using MATLAB, which supports batch mining; leading fundamental factors into correspondence analysis with identification indexes; reminding the selected stocks, so as to verify the reliability of the identification indexes. According to the above research, something can be learned: In A-share markets, the higher the discriminant index value is, the less number of shares meeting the requirements is; the same discriminant index value, the stock proportion has difference among plates. Confidence P1, P2 and Lift are extremely related to the GC (General Capital), and Lift is extremely related to the Ind (Industry). In the GEM, confidence P1 of mid-cap is near [0.7,1], Lift is near (1,3), confidence P1 of the manufacturing industry is near [0.7,1].
