General Convex Integral Control

引用

International Journal of Automation and computing 2014年第5期11卷 565-570页

作者： bai-shun Liu Xiang-Qian Luo Jian-Hui Li Academy of Naval Submarine

In this paper, a fire-new general integral control, named general convex integral control, is proposed. It is derived by defining a nonlinear function set to form the integral control action and educe a new convex function gain integrator, introducing the partial derivative of Lyapunov function into the integrator and resorting to a general strategy to transform ordinary control into general integral control. By using Lyapunov method along with the LaSalle s invariance principle, the theorem to ensure regionally as well as semi-globally asymptotic stability is established only by some bounded information. Moreover, the lemma to ensure the integrator output to be bounded in the time domain is proposed. The highlight point of this integral control strategy is that the integral control action seems to be infinity, but it factually is finite in the time domain. Therefore, a simple and ingenious method to design the general integral control is founded. Simulation results showed that under the normal and perturbed cases, the optimum response in the whole control domain of interest can all be achieved by a set of control gains, even under the case that the payload is changed abruptly.

The point spread function reconstruction by using Moffatlets–I

Research in Astronomy and Astrophysics 2016年第9期16卷 51-64页

作者： bai-shun Li Guo-Liang Li Jun Cheng John Peterson Wei Cui Purple Mountain Observatory Chinese Academy of Sciences Nanjing 210008 China University of Chinese Academy of Sciences Beijing 100049 China Department of Physics Purdue University 525 Northwestern Ave West Lafayette Indiana 47907 USA

Shear measurement is a crucial task in current and future weak lensing survey projects. The reconstruction of the point spread function （PSF） is one of the essential steps involved in this process. In this work, we present three different methods, Gaussianlets, Moffatlets and Expectation Maximization Principal Component Analysis （EMPCA）, and quantify their efficiency on PSF reconstruction using four sets of simulated Large Synoptic Survey Telescope （LSST） star images. Gaussianlets and Moffatlets are two different sets of basis functions whose profiles are based on Gaussian and Moffat functions respectively. EMPCA is a statistical method performing an iterative procedure to find the principal components （PCs） of an ensemble of star images. Our tests show that：（1） Moffatlets always perform better than Gaussianlets. （2） EMPCA is more compact and flexible, but the noise existing in the PCs will contaminate the size and ellipticity of PSF. By contrast, Moffatlets keep the size and ellipticity very well.

目的探究宫腔粘连(IUA)分离术后患者冻融周期囊胚移植的助孕策略及其影响因素。方法收集因不孕因素行冻融周期囊胚移植的IUA分离术后患者275例,分成单囊胚移植组(n=182)与双囊胚移植组(n=93),对两组患者临床结局进行回顾性分析。结果两组患者在年龄、转化日子宫内膜厚度、内膜准备方式、临床妊娠率、流产率、早产率、分娩孕周、分娩方式之间的比较,差异无统计学意义(P>0.05)。单囊胚移植组的不孕年限(2.43±1.64)年,AFS预后评分(5.13±2.25)分,多胎率1.33%低于双囊胚移植组的不孕年限(3.03±2.13)年,AFS预后评分(5.72±2.19)分,多胎率28.57%;单囊胚移植组的优胚率90.66%,种植率50.00%,活婴体质量(3 236.84±565.35)g高于双囊胚移植组的优胚率46.24%,种植率34.41%,活婴体质量(2 976.44±692.79)g,差异有统计学意义(P <0.05)。logistic回归分析显示,移植优质胚胎数目、AFS评分是临床妊娠的独立影响因素(P <0.05)。结论冻融周期囊胚移植IUA术后患者的移植优质胚胎数目、AFS评分是临床妊娠的独立影响因素。优质单囊胚移植是IUA分离术后患者行冻融周期治疗的首选,对于低预后IUA术后患者可以选择双囊胚移植有助于获得更好的妊娠结局。

壳寡糖(chitosan oligosaccharide,COS)是由壳聚糖通过物理、化学或酶水解等方法脱乙酰解聚得到的多糖,是自然界中唯一具有正电荷的阳离子碱性氨基寡糖,其主要来源于虾壳、贝类等甲壳类水生物。根据分子量、聚合度、脱乙酰度、电荷分布、各单元排列方式不同,COS能表现出不同的物理化学特性,然而,COS的生物活性主要来自于各单元的羟基和氨基。由于COS具有诸多特殊活性(如抗菌、抗氧化、抗炎等),目前已经被广泛应用于医学、化妆和农业等多个领域,但在食品领域的应用相对较少,且对COS的生物活性及在食品添加剂方面的应用缺乏系统总结报道。本文通过对COS的结构、性质以及其生物活性的阐述,总结了COS在食品添加剂中如保鲜剂、功能因子添加剂、风味改善剂中的应用与发展,对COS在食品加工领域未来的发展进行展望,为食品加工方面的应用提供新思路。

目的探究魔芋葡甘露聚糖(konjac glucomannan,KGM)、海藻酸钠(sodium alginate,SA)、巴西棕榈蜡(carnaubawax,CW)与金丝桃素-β-环糊精络合物(hypericin-β-cyclodextrin complex,Hyp-β-cd)制备的光敏性保鲜膜在4℃储藏条件下对小龙虾的品质影响。方法将制备的Hyp-β-cd加入到KGM、SA与CW溶液中,采用流延法制备光动力杀菌保鲜膜(KGM/SA/CW/Hyp-β-cd膜),通过核磁共振光谱(nuclear magnetic resonance spectroscopy,NMR)与荧光猝灭法验证了Hyp-β-cd的形成和活性氧(reativ oxygen species,ROS)的生成能力,然后用正交实验法对复合膜的制备进行优化。通过扫描电子显微镜(scanning electron microscope,SEM)、傅里叶红外光谱(Fourier transform infrared spectroscopy,FTIR)、X射线衍射(X-ray diffrction,XRD)进行表征,最后,以pH、总挥发性盐基氮(total volatile basic nitrogen,TVB-N)、菌落总数及硫代巴比妥酸反应物(thiobarbituric acid reactants,TBARS)值做为指标对保鲜效果进行评估。结果NMR及荧光猝灭的结果表明Hyp-β-cd的形成和ROS的生成,通过正交实验法对复合膜的制备进行优化:KGM含量为0.7%(m/V,下同)、SA含量为1.2%、CW含量为0.6%、Hyp-β-cd含量为0.4%时,复合膜有最优机械性能,拉伸强度为51.84MPa,断裂伸长率为14.27%。SEM证明了各物质在复合膜中的均匀分布。FTIR与XRD结果表明,随着SA、CW与Hyp-β-cd的加入,KGM与SA之间形成氢键,提高了复合膜的物理性能,CW的加入减少了复合膜的微孔隙,其中水接触角从67.5°增加到88.7°,氧气透过率从32.96降低到22.37 m^(3)·μm/m^(2)·day·kPa。由KGM/SA/CW/Hyp-β-cd膜包裹且在黄色LED光源照射处理后的小龙虾,在第8d时TVB-N值为20.37mg/g,菌落总数为6.14lgCFU/g,TBARS值为0.85 mg/kg,pH超过7.6。结论KGM/SA/CW/Hyp-β-cd复合膜具有作为光敏性抗菌包装材料的潜在应用价值。
