摘要：The Lancang–Mekong River basin(LMRB) is under increasing threat from global warming. In this paper, the projection of future climate in the LMRB is explored by focusing on the temperature change and extreme temperature events. First, the authors evaluate the bias of temperature simulated by the Weather Research and Forecasting model. Then, correction is made for the simulation by comparing with observation based on the non-parametric quantile mapping using robust empirical quantiles(RQUANT) method. Furthermore, using the corrected model results, the future climate projections of temperature and extreme temperature events in this basin during 2016–35, 2046–65, and 2080–99 are analyzed. The study shows that RQUANT can effectively reduce the bias of simulation results. After correction, the simulation can capture the spatial features and trends of mean temperature over the LMRB, as well as the extreme temperature events. Besides, it can reproduce the spatial and temporal distributions of the major modes. In the future, the temperature will keep increasing, and the warming in the southern basin will be more intense in the wet season than the dry season. The number of extreme high-temperature days exhibits an increasing trend, while the number of extreme low-temperature days shows a decreasing trend. Based on empirical orthogonal function analysis, the dominant feature of temperature over this basin shows a consistent change. The second mode shows a seesaw pattern.

摘要：1引子:五龙庙带来了西侯度2016年,URBANUS都市实践在山西省运城市芮城县设计完成的五龙庙(又称广仁王庙)环境整治工程(后文简称"五龙庙项目"),曾引起文保界和建筑界之间广泛而长期的讨论。五龙庙项目的建筑师王辉认为那是一场由于一般建筑师涉入文保领域后因不谙熟专业禁忌而引发的学术讨论[1]。

摘要：液压四足机器人髋关节由伺服阀控缸系统构成,是机械腿的关键组成部分.它的控制性能直接影响着机械腿甚至机器人的运动控制精度.因为髋关节工作情况的复杂性和阀控缸系统自身的非线性,使得传统控制算法无法满足机器人运动性能指标的要求.由此,本文对液压四足机器人髋关节伺服阀控缸系统的控制方法进行了研究.首先通过对髋关节工作条件的分析完成了伺服阀控缸的数学建模,然后基于鲁棒自适应动态面的控制算法设计了伺服阀控缸系统的控制器,并从李雅普诺夫稳定判据的角度证明了系统的稳定性.最后通过Matlab与AMESim的联合仿真,对鲁棒自适应动态面与传统PID及普通动态面的控制效果做出对比,证明了所研究算法的有效性.

摘要：软岩深基础端阻力值计算问题一直工程界较为关注的问题,目前我国规范一般采用单轴抗压强度frc乘以折减系数(远小于1)计算软岩端阻力值,但其远小于载荷试验值。大量工程实践表明,规范考虑的折减系数偏小,实际工程甚至存在端阻力测试值大于其单轴抗压强度frc值。旁压试验曲线与载荷试验曲线出现的直线段和弯曲段类似,用其试验参数确定的软岩端阻力值与实际值较为相符。主要探讨根据软岩各类试验强度参数计算其深基础端阻力的方法,单轴抗压强度、三轴试验参数和标准贯入度击数等参数计算的软岩端阻力值,但仅可作为工程勘察建议参考的初设值,在积累足够地区经验后,可用于二级或荷载不大的一级建筑物软岩端阻力设计值;载荷试验值是端阻力设计计算最为可靠的依据,通过对比试验后,旁压试验参数用于计算软岩端阻力设计值也较为可靠。

摘要：随着获取渠道的多样化以及采集过程的规范化,数据普遍具有多维、时空属性.由于不同的属性维度中数据的分布方式和表达意义各不相同,针对数据的多维时空属性开展综合的分析和全面的探索存在较大的困难.为此,提出一种多维时空数据协同可视化方法.首先设计属性关联视图展现空间对象的多维属性数据及其关系;然后利用MDS算法将原始多维属性数据按照时间顺序关系分别降解至一维空间构建时序平行坐标系,并且对各时间轴的投影坐标点进行布局优化和层次聚类操作,利用信息熵度量类别的稳定性对平行坐标系中点和线的颜色进行映射;最后设计圆状布局的层次链接图,展示感兴趣特征的层次结构关系.文中通过设计便捷的交互模式有效地关联各个视图的可视化设计,构建多维时空数据协同可视分析系统.GDP数据和空气质量监测数据的实例分析结果表明,文中方法能够综合考虑多维时序属性,帮助用户快速探索数据中隐含的特征模式;专家用户的反馈进一步验证了该方法的有效性和实用性.
