Simulation for Logistics in Steel-making Process of Panzhihua Iron and Steel Corporation

To solve potential scheduling problems in production after renewal of continuous casting process in Vanadium-extracting and Steel-making Plant of Panzhihua Iron and Steel Corporation (PISCO), how to model and simulate logistics system in steel-making processhas been discussed. A series of simulatingtests for logistics system in steel-making processhave been conducted based on inputs of presentsteel-making processof PISCO. In the tests, cases of regular schedule case and cases with repairing converter have also been regarded as essential simulation condition. It has been shown that three casters can not start at same time in order to ensure continuous hot metal supply for casters when three kinds of steel are made. It has also been shown that the simulation system for logistics system in steel-making processis valid and can be used for simulating logisticsin upcoming 100% continuous casting process of PISCO. The better schedule scheme of production and reasonable match of converter-caster in time and capacity can be achieved with the help of using simulation approach.     

Examining brain oedema through brain electrical impedance topographic mapping

Change of Brain Electrical Impedance has great relations with brain oedema and brain block, a new method of Examining Brain Oedema through Brain Electrical Impedance Topographic Mapping(BEITM)is reviewed. Network topology structure that used in BEITM are also presented. According to topology, we discuss the drawing algorithm that based on triangle element. Some patients have been measured to make clinical data, according to this data Brain Electrical Impedance topographic come into being by computer at last, functional imaging has been implemented. Clinical case analysis compared with change state of an illness and repeatability of steady patient's data has proved the method is feasible.

N+离子注入对萌发期小麦中POD和SOD同工酶的影响

采用垂直板聚丙烯酰胺凝胶电泳技术,研究N+离子注入处理后小麦种子豫麦34萌发时期根、盾片、芽、胚乳中POD和SOD同工酶的变化.结果表明:N+离子注入可引起豫麦34的不同器官中POD和SOD同工酶的酶带与酶活性的不同变化,除芽中POD和SOD同工酶活性无明显变化外,其它器官中POD和SOD同工酶均表现为活性增强.4种器官相比,根和胚乳中同工酶变化较大,盾片和芽中同工酶变化不明显.其中,根中同工酶变化更为显著,N+离子束注入处理后根中POD同工酶多了Rf值为0.47的新酶带.     

Technologies of Intelligent Vehicle in Intelligent Transportation System (ITS)

Intelligent Transportation System (ITS) is the most effective method to solve the modern traffic problems. Intelligent vehicle plays a very important role on ITS, and it influences the success of ITS directly. Intelligent Transportation System (ITS) is briefly introduced. Then it is given that advanced vehicle control system and electrics stability program (ESP) in the key technology of intelligent transportation system. The control algorithm for vehicle movement is discussed and the test result is given.     

Research and Realization of Calculating Artery Compliance Using Oscillometric Method

This paper presents a method that can non-invasively detect artery compliance using oscillometric method.There are also researches about Windkessel theory,and analysis of the combination of Windkessel and oscillometric method.Then the authors summarize a method to calculate artery compliance and introduce the clinical effect in the hospital.Compared with traditional sphygmomanometer,they get the pertinence of SBP is r=0.918 5(P<0.001).And the pertinence of DBP is r=0.899(P<0.001).Then it is compared with ultrasonic method,the pertinence of compliance is r=-0.820 9(P<0.01).This proves that the diagnose of blood pressure and artery compliance is effective and artery compliance is an important index in cardiovascular clinical measurement.So this paper makes the oscillometric method to be applied to wide ranges in calculating cardiovascular indexs.     

超级稻新组合Y两优3218在桂北高寒山区的水气平衡栽培示范

于2009年在桂北高寒山区三江侗族自治县开展两系超级杂交水稻新组合Y两优3218水气平衡栽培示范。结果表明:示范区平均株高119.9 m、穗长27.3 cm、有效穗数16.64万穗/667 m2、成穗率74.36%、穗实粒159粒、结实率80.85%、千粒重27.4 g、单产715.05 kg/667 m2,与对照区相比,除株高、穗长和穗实粒数相差不大外,其他各项指标均明显高于对照区,其中以单位面积产量增幅最大,达28.91%;成穗率次之,达18.22%;单位面积有效穗数再次之,达12.74%;穗实粒数和千粒重的增幅则分别达9.85%和9.16%。同时还介绍了Y两优3218的特征特性及其配套水气平衡栽培技术,并对其在当地的推广应用前景进行了分析预测。     

球孢白僵菌分离培养基的筛选及应用

为获得理想的白僵菌分离培养基,以PPDA培养基作为基础培养基,通过观察白僵菌和杂菌在不同抑菌剂和不同抑菌剂浓度的菌落数,筛选出白僵菌生长良好,杂菌被尽可能抑制的培养基配比。结果表明,在PPDA培养基中添加70 mg/L的多果定,125 mg/L头孢霉素和138 mg/L硫酸卡那霉素为最适筛选培养基。用筛选出的培养基检测白僵菌悬乳剂和颗粒剂在田间施药后30天内的含菌量变化,发现在空气中孢子含量,白僵菌悬乳剂比颗粒剂含量更持久,证明本研究获得的筛选培养基具有实际的应用价值。     

Temporal-spatial Filtering in the Preprocessing of Clinical EEG Signals

EEG spot-recording for clinical patients in the bed is always advocated due to easing patients and making them comfortable. But EEG signals recorded in the ward exposed to various noisesand interference is less effective in the EEG analysis. Atemporal-spatial filter is designed for noise removing of clinical EEG signals, the first filtering is temporal filtering using band-pass filter, and the second filtering is spatial filtering with ICA-based spatial filter. Experimental results indicate that various noises and interferences, such as power interference, blinking, eyes movements, muscle moments, ECG artifacts, etc., are removed effectively, individually or simultaneously.
