A new inverse method and application to ocean data

A new method is proposed to inverse normalization data of hidden variables in a dynamical system by embedding a time series in multidimensional spaces and applying a normalization analysis to the conditional probability density of points in the reconstructed phase spaces. The method is robust in the application to Lorenz system and 4-dimensional R?ssler system by testing quantitatively and qualitatively the correlation coefficient between inverse data and original data in time domain and in frequency domain, respectively. By applying the method to analyzing the South China Sea data, the normalization data of wind speed is extracted from the sea surface temperature time series.     

Elastic waves in visco-elastic half-space generated by various vehicle loads

In this paper, the response of a visco-elastic half-space subjected to moving loads with static and dynamic components is investigated. Four types of vehicle loads are considered, including the moving point load, uniformly distributed wheel load, elastically distributed wheel load, and a train load simulated as a sequence of elastically distributed wheel loads. In each case, the influence of the moving loads traveling in the subsonic, transonic and supersonic ranges on the dynamic responses of the half-space is studied. The parametric study conducted herein enables us to grasp insight into the mechanism of wave propagation for a visco-elastic half-space under moving loads.     

Jewish settlement of Hebron: The place and the other1

Kiryat-Arba and Jewish Hebron are communities planted in the most heated front of the Israeli-Palestinian conflict. This paper examines how the Hebron Jewish settlers' collective memory interprets the `truth' of Hebron as a typical Israeli Place that reveals Zionism in its purest form. Today the populations of Kiryat-Arba and of the Hebron Jewish enclaves number about 5,000 and 500, respectively. Kiryat-Arba functions as an economic and educational centre for the nearby Jewish settlements in the region. Rejecting the segregative concept of a separate Jewish settlement overlooking Hebron, the settlers treat Kiryat-Arba as part of Hebron. Some 70,000 Palestinians live in Hebron, many more residing in neighbouring towns and villages, cutting Hebron – Kiryat–Arba off from the nearest Jewish urban centres of Jerusalem and Beer-Sheva. The settlers initiated the narrative of `Return' to the city after the massacre of Jews in 1929 in the city, as the key symbol Symbolically, the first place Hebron Jews reidentified with was its ancient Jewish graveyard. Today, IDF soldiers protect settlers and their visitors who want to tour Hebron. The huge gulf between `metaphorical Hebron' as a symbolic centre and `actual Hebron' as a poor development town creates tensions fuelling violent events. The Jews in Hebron take the Israeli logic of `Place' making to its extreme, thus testing concepts of Israeli territoriality. If Israeli society rejects Hebron as a `Place' constructed from intense memories and violent national encounters, it would leave the Hebron Jews out of the so-called Israeli normalcy.

长期预报的相空间近邻等距法

考虑到确定性系统的外在随机因素和内在随机性(浑沌)所造成的长期预报的不准确性,本义将有关浑沌的理论和数理统计理论结合起来,提出了d维相空间距平符号传播的“正、反规则”假说和近邻等距模式.实例检验表明,经调试后距平符号的报准率一般为66％—80％,而相对误差一般不大于8％.     

我国日照时数和总辐射的空间分布场

运用多项式回归分析和双随机样本检验,模拟日照时数和总辐射及其影响因子(可照时间、总云量和天文辐射、日照百分率)年值和1月值、7月值的三度空间分布场,取得了满意结果。这可应用在无测站地区,仅凭经纬度和海拔估算出上述气候要素值,估算的平均相对误差大多在5％以下(最好的达0.3‰)。     

中国东部新生代火山岩的地质特征及火山作用发育的某些共同规律

中国东部从黑龙江到海南岛的广大范围内新生代玄武岩广泛发育。根据构造关系笔者把本区划分为三个部分：北、中和南构造地块。新生代火山作用在时空上表现出明显的分带。从老到新，火山作用演化的特点是ＳｉＯ２饱和程度减少，碱金属和镁含量增加。从南构造地块到北构造地块出现的玄武岩各具特色。从东南沿海向西北方向，即从东南沿海断裂经长白山－郯庐断裂到大兴安岭－太行山断裂方向，是地壳厚度增加的方向，新生代火山活动的演化
