A comparative study and unification of two methods for controlling dynamically substructured systems

This paper addresses the problem of advanced testing of systems via the principle of dynamic substructuring. Use is made of the hybrid simulation (HS) scheme framework to develop a new method of synthesis for the dynamically substructured system (DSS) scheme of Stoten and Hyde. Principal reasons for doing this are (i) to improve upon the original method of DSS synthesis by adopting the more intuitive framework of HS and (ii) to enable the amalgamation of HS and DSS into a unified substructured system (USS) scheme, so that the significant advantages of DSS can be incorporated into an existing HS scheme as a straightforward retrofit. Having established the common framework for HS/DSS, the paper also illustrates, by way of an example, compensator/controller synthesis for the two schemes, together with their advantages and disadvantages. In doing this, both schemes are retained in their basic forms, that is, there are no additional control embellishments used in this work, such as delay compensation, adaptive control, or other advanced control methods. In order to maintain as much transparency as possible, use is made of well‐known classical control techniques. Common problems associated with the substructure testing technique are also investigated, including the effects of physical parameter uncertainty, pure delays in signals, and a ‘split‐mass’ in the substructure formulation. It is shown that, although the new formulation of controlled DSS requires more design effort than compensated‐HS, the advantages of DSS in terms of stability and robustness significantly outweigh this small disadvantage at the design stage.

东北地区县域老年人口高龄化空间分异特征及驱动因素研究

基于2000年和2010年人口普查数据,运用高龄人口比重等指标和空间自相关等方法,分析东北地区县域老年人口高龄化的空间分异特征,并利用地理探测器方法分析其驱动因素。研究表明：① 10 a间高龄化水平升级的态势明显,高龄化区域呈蔓延式扩散。高龄化在省级行政区间、城乡间、民族自治地区与非民族自治地区间、贫困与非贫困地区间存在显著差异。② 10 a间高龄化的变动趋势差异显著,但长期以来形成的高龄化的总体空间格局较为稳定。③ 县际间高龄化呈现较强的正的空间自相关性,空间聚集特征明显。高龄化的空间格局具有以热点区为中心,逐渐向边缘区过渡的“中心-外围”的空间梯度差异特征。④ 高龄化是老年人口年龄结构继承性和迟滞性的体现,自然环境和社会经济是影响高龄化空间分异的基础性因素,可以引导和制约高龄化空间分异的程度和方向。     

基于SVM回归模型的SAR图像有效波高估测

A new method for estimating significant wave height(SWH) from advanced synthetic aperture radar(ASAR) wave mode data based on a support vector machine(SVM) regression model is presented. The model is established based on a nonlinear relationship between σ0, the variance of the normalized SAR image, SAR image spectrum spectral decomposition parameters and ocean wave SWH. The feature parameters of the SAR images are the input parameters of the SVM regression model, and the SWH provided by the European Centre for Medium-range Weather Forecasts(ECMWF) is the output parameter. On the basis of ASAR matching data set, a particle swarm optimization(PSO) algorithm is used to optimize the input kernel parameters of the SVM regression model and to establish the SVM model. The SWH estimation results yielded by this model are compared with the ECMWF reanalysis data and the buoy data. The RMSE values of the SWH are 0.34 and 0.48 m, and the correlation coefficient is 0.94 and 0.81, respectively. The results show that the SVM regression model is an effective method for estimating the SWH from the SAR data. The advantage of this model is that SAR data may serve as an independent data source for retrieving the SWH, which can avoid the complicated solution process associated with wave spectra.     

鲁西地区早前寒武纪地质研究新进展

近年来在鲁西地区早前寒武纪结晶基底进行锆石SHRIMP测年结果显示,泰山岩群形成年龄大约在2770～2750Ma。新太古代发生3期岩浆侵入活动,每期岩浆侵入活动开始都有地幔岩浆侵入。早期构造岩浆活动主要形成2740～2700Ma的英云闪长质片麻岩、条带状英云闪长质片麻岩;中期构造岩浆活动主要形成2650～2600Ma的TTG质花岗岩;晚期构造岩浆活动最强烈,从地幔岩浆侵入到地壳深熔形成大规模的钾质花岗岩,导致大规模陆壳的形成。古元古代早期和中元古代,有少量岩浆沿太古代刚性陆壳裂解形成的张性裂隙侵入。对鲁西地区前寒武纪侵入岩按岩性＋时代进行了重新划分,变质深成侵入体（片麻岩）按时代＋gn,依据其不同成分和不同结构构造的第一个英文大写字母进行表示,探讨了鲁西地区早前寒武纪陆壳演化历史。
