Policy Optimization Study Based on Evolutionary Learning

In order to achieve an intelligent and automated self-management network,dynamic policy configuration and selection are needed.A certain policy only suits to a certain network environment.If the network environment changes,the certain policy does not suit any more.Thereby,the policy-based management should also have similar natural selection process.Useful policy will be retained,and policies which have lost their effectiveness are eliminated.A policy optimization method based on evolutionary learning was p...

Structural Prediction of Membrane Protein: Application to Known Structures

Membrane proteins are embedded in the lipid bilayer,which creates a suitable environment for their actions. It is important to decide which tpye it belongs to because it is closely relevant to its biological fumction and its interaction process with other molecules in a biological system. Membrane proteins have different types. The function of a membrane protein is closely correlated with the type it belongs to. In this study, on the basis of the concept of pseudo amino acid (PseAA) composition originally introduced by Chou, the value of approximate entropy (ApEn) of the query membrane protein was used to integrate the complementary information. By fusing fifteen powerful individual fuzzy K-nearest neighbor (FKNN) classifiers, an ensemble classifier was presented.Each basic classifier was trained in PseAA composition of membrane protein sequences with different parameters. The results of experiments demonstrate it is efficient for the structural prediction of membrane proteins.

Research on a New-style Pipeline Inspection Robot System

IntroductionRecently pipe is used widely on the industry,agriculture and daily life. Natural gas and oil supplybecomes one of the fundamental public services and itsimpact on the urban infrastructure is getting larger. Theurban oil/gas pipelines, as they are buried under theground, are prone to external corrosion usually derived bymoisture and chemical agent in soil, which causes materiallosses of the pipe wall. Also, cracks in the welded regionand the da…     

贝壳棱柱层和珍珠层的傅里叶变化红外光谱

运用热重分析和傅里叶变换红外光谱分析技术,对夏夷扇贝棱柱层和珍珠层粉末样品进行温度变化性质研究.研究结果表明,贝壳棱柱层和珍珠层的主要成分均为方解石型碳酸钙,并含有少量有机质和水分,棱柱层有机质含量高于珍珠层.珍珠层和棱柱层样品分别于600℃、700℃发生碳化,所含有机物分别于700℃、800℃发生完全分解,同时热处理前后红外光谱吸收峰的峰形、峰位发生了明显变化,有机质含量的高低与CO32-不对称伸缩振动ν3的峰位负相关,而与CO32-的面内弯曲振动2ν、面外弯曲振动ν4无关.变化表明,热分解前存在生物大分子与方解石型碳酸钙的配位作用,从分子结构水平上揭示了生物矿化材料中有机质对无机晶体的配位作用.
