A paper with an interest in rhythm

This paper is a performative effort to move with and through the expressive and theoretical spaces of an interest in rhythm. This interest emerges initially from the middle of an encounter with the 5 Rhythms™, a contemporary somatic practice that uses rhythm to facilitate and catalyse expressive movement. Rather than seeking to excavate representational meaning from an encounter with the practice or using it to critically diagnose the corporeal politics of contemporary society, this paper apprehends the creative movement emerging from an encounter with/in the non-representational, performative potential of the 5 Rhythms™. By becoming a deliberately playful effort to hold onto the lines of movement emergent from the affective, kinaesthetic territories of this practice, the paper works to avoid either falling back upon a representational ethics that stops this movement dead in its tracks or becoming seduced by an aesthetics of weightless escape. This effort draws particular support from Deleuze and Guattari's writing on the refrain, a concept that provides a vehicle through which the lines of an interest in rhythm gain expressive and theoretical consistency. Because the territories of the refrain open onto lines of movement that are as much figural as discursive, the paper works to animate the lines of movement emerging from an encounter with the 5 Rhythms™ through a series of non-representational diagrammatic interventions. Finally, in drawing the diagrammatic lines of this movement in-between, the paper becomes not so much a series of lines about moving, but a series of lines moving about.

南北地震带北段流体资料地震预测效能检验

以南北地震带北段长时间、 连续并有多次震例记录的流体观测资料为研究对象, 使用Molchan图表法对其与周边地震的关系进行了检验和分析, 计算了时间占有率、 预测效能和概率增益等参数。 结果表明, 南北地震带北段各台项的预测效能差别较大。 整体看来, 甘东南地区的观测资料检验效果较好, 表现为概率增益较大; 青海东部地区的多个测项预测效能检验结果较好, 但概率增益较小; 宁夏北部贺兰山东麓断裂附近两台项的报准率差别不大, 但概率增益、 时间占有率等却都不同。 此外, 从前兆资料变化时间上看, 短期异常和长期异常都较多, 中期异常较少。     

线实体候选匹配集的优化方法研究

地图数据合并是地理空间数据集成的基本途径,同名实体匹配是其中的重点与难点。本文根据线实体的形状将其分为简单线实体与复杂线实体,提出针对前者以线实体端点与中点为发生元生成的Voronoi图所得到的邻近对应关系为依据、针对后者以基于线实体缓冲区重叠度构造的相似性测度指标为依据优化候选匹配集的思路,并设计与实现了相关算法。实证研究表明,该算法能够适应不同比例尺与不同时相的城市道路网地图数据同名实体匹配。     

A Boundary Delineation System for the Bureau of Ocean Energy Management

Federal government mapping of the offshore areas of the USA in support of the development of oil and gas resources began in 1954. The first mapping system utilized a network of rectangular blocks defined by State Plane coordinates which was later revised to utilize the Universal Transverse Mercator grid. Creation of marine boundaries directed by the Submerged Lands Act and Outer Continental Shelf Lands Act were mathematically determined using early computer programs that performed the necessary computations, but required many steps. The Bureau of Ocean Energy Management is revising these antiquated methods using Geographic Information System technology which will provide the required accuracy and produce the mapping products needed for leasing of energy resources, including renewable energy projects, on the outer continental shelf.

Maucha图的Matlab实现及其在水化学中的应用

水中可溶性离子的含量及各离子的比例关系是衡量水质的重要指标,但常用的方法不能同时反映这两种关系。Maucha图既可以反映8种主要阴、阳离子的总浓度,同时也可以指示各离子的相对浓度,兼顾了离子的绝对含量和相对含量,具有较强的实用性。但由于缺乏绘制Maucha图的专业软件,导致Maucha图在实际应用中受到很大限制。通过介绍Maucha图的演化过程,绘制Maucha图时建立坐标系及确定Maucha图各组成部分坐标值的方法,并阐述了基于Matlab语言实现Maucha图计算机输出的编程流程。最后以内蒙古浑善达克沙地东部地区为例,说明了Maucha图在天然水体水化学分析中的应用。该应用表明,Maucha图在反映样品矿化度、指示各离子的相对浓度和绝对浓度、判断水体水化学类型及水化学数据空间分析等方面均具有较强的优势,能显著提高水化学数据的可视化表达能力,丰富水化学图在水文地质中的应用,并为水化学数据更深层次的分析提供参考依据。

Unusual behavior of the Kuroshio Current System from winter 1996 to summer 1997 revealed by ADEOS-OCTS and other data— Suggestion of topographically forced alternating-jet instability

While the Advanced Earth Observing Satellite (ADEOS) was operating, the Kuroshio and the Kuroshio Extension, or the Kuroshio Current System, exhibited unusual behavior from the winter of 1996 to the summer of 1997. This behavior of the Kuroshio Current System has been closely studied using a time series of satellite observation images of SST and ocean color obtained by ADEOS-OCTS, reinforced by SST images obtained by NOAA-AVHRR. Our findings include (i) a long lasting, very southerly path of the Kuroshio Extension; (ii) a Kuroshio path very distant from Japan with the following alternating-jet-like north-south flow pattern of the Kuroshio Extension, which occurred twice, once in February and once in April 1997, as independent events and which was observed to be affected by the bottom topography of the Izu-Ogasawara Ridge and Trench, and of the Japan Trench; (iii) cutting off of a cold water mass after the February event; and (iv) the formation of a vortex pair after the April event. A new mechanism is suggested for the formation of the alternating-jet flow pattern: a topographically forced alternating-jet instability (AJI). An SST-Chlorophyll Diagram (T-Chl Diagram) generated using simultaneous data from a single satellite is useful for analyzing the water mass structure of this region, including biological processes.
