Regional representation of glaciers in Chandra Basin region,western Himalaya,India

Hamtah and Chhota Shigri are two nearby, well monitored glaciers of western Himalaya, lying in the same climatic zone and driven by the same climatic conditions. In this study, topographical characteristics of both the glacier have been explored to understand the role of topography in controlling the glacier response. Further, their topographical characteristics and possible response towards climatic variations have been compared with each other and also with that of the other glaciers in the basin to find out the suitability of these two glaciers to be considered as representative of the region. Multi sensor and multi temporal remote sensing data have been used to carry out to fulfill the objectives. It is found that being in the same climatic zone, the mean accumulation area ratio of Chhota Shigri is 54% and Hamtah is 11% between 1980 and 2014. In comparison to Hamtah, Chhota Shigri glacier has a small upslope area, low compactness ratio indicating the ability of the glacier to receive direct precipitation and solar radiation. The analysis revealed that the Chhota Shigri glacier has a closer resemblance with the other glaciers in the region than Hamtah glacier. Also, the topographical settings of Chhota Shigri glacier are suitable for recording and reflecting year-to-year climatic variations.     

顾及形变控制的小屏幕变比例尺交通路线图生成方法

用户在旅游或者室外运动中经常将路线图显示于移动设备上以方便规划路线。然而移动设备显示屏幕通常较小,若较大范围的地图通过等比例尺缩小在小屏幕显示,可能会导致清晰度和辨识度的降低,尤其对于地图中地物较为密集的区域。本文提出一种自动化生成变比例尺地图的方法,通过更加均匀化地图显示内容密度分布以改善地图概览清晰度。在该方法中,首先对密度分布进行估计,密度估计主要考虑地图上路线空间分布以及地标与注记显示空间,然后根据所得到的密度分布进行变比例尺转换,最终生成的变比例尺结果图,其大小取决于给定显示尺寸。相较于现有变比例尺转换方法,本文提出的方法可以考虑了地标与注记显示空间,同时又能有效控制地图变形以提高地图识别。实验结果表明,通过本方法生成变比例尺结果图对地图概览的清晰度有着显著提高,并且能够保持良好的地图识别度。     

Forcing the boundaries of genre: the imaginative geography of South America in Luis Sepulveda's Patagonia Express

This article considers how literary genre conditions the influence of imaginative geographies on textual representations of place and space. Focusing on a central case study, it argues that the representation of South America in Luis Sepulveda's popular travelogue Patagonia Express is the product of interplay between two competing forces: the boundaries imposed by the travelogue genre and a widely-circulated imaginative geography of South America as a space where 'the fantastic' or magical is inherent to everyday reality.

资源信息系统的多层次结构与功能

对应于人口、资源、环境与经济这些复杂系统的信息系统,其结构是多层次的。分别应用于国家宏观决策、地区开发与城市建设。对于空间型与统计型各有侧重。我国资源信息系统起步较晚,进展参差不齐,还不配套。人口数据库缺乏空间型结构:经济数据库属于统计型结构;而海洋环境与资源信息系统则系文献检索的性质。资源信息系统的功能,不应局限于检索、查询,而应走向高层次的分析、模拟与预测。目前已经具备回答决策过程中的一些主要命题,诸如:数据可靠性、资源容量、环境适应性、交通的接近度、工程的可行性和生产的稳定性。正在进一步为建立系统动力模型和专家系统而努力。     

辽南石英岩板岩区基岩地下水富集规律及富水点位的研究

文章从辽东半岛南部石英岩板岩区地下水富水不均的特点出发，论述了基岩地下水富集规律：贮存在蓄水构造中，汇集在集水网络里，运移富集在充水脉络交接、结点处。进一步对水文物探各类富水曲线进行了分类，概括富水异常特征。结合多年实际勘测成果，论证了依据“结点异常”确定富水点位。

SHORT COMMUNICATION PATTERN RECOGNITION IN CLINICAL CHEMISTRY:TUMOR MARKERS

Pattern recognition techniques(PCA,Bayesian analysis,LDA and KNN)are applied to a set of datacomposed of cancer patients and controls.A rather good separation between different populations isobtained using four tumor markers determined for each patient.
