Paleoart: Visions of the Prehistoric Past

Abstract

Cartography in general, and building solid landscape models in particular, requires an interdisciplinary set of skills in order to be done well. Traditional handcrafted construction methods provide quality results, but are extremely labour-intensive and therefore costly. Modern methods using digital terrain models (DTMs) and computer numerical control (CNC) milling are fast and accurate, but the finished models are visually less than optimal. Solutions are proposed using DTMs and CNC milling to create landscape models in which the initial shaping is done mechanically and the fine details are carved by hand. This ‘balanced approach’ to landscape modelling combines the time- and cost-advantages of modern digital technology with the quality of traditional handcrafted techniques resulting in highly accurate landscape models which still retain the artistic ‘feel’ of the human touch.     

SPATIAL,SYNOPTIC, AND SEASONAL PATTERNS OF HEAVY RAINFALL IN THE SOUTHEASTERN UNITED STATES

This paper examines the synoptic climatology and seasonality of heavy rainfall across the southeastern United States. Frontal systems (particularly cold fronts) were found to be the dominant mechanism that induces heavy rainfall across the study area, but tropical disturbances and air-mass storms also contribute, especially at the more coastal locations. Annual regimes were found to vary dramatically from one site to another, and seven of the eight sites investigated exhibited statistically significant seasonality. Generally, peaks in heavy rainfall are bimodal in the western portion of the region, occurring in the transitional seasons. The central portion of the region peaks in late winter and spring, whereas the area east of the Appalachians (including Florida) has summer peaks. This spatial pattern is likely related to patterns of mid-tropospheric air flow and positions of the Bermuda High in summer, and the seasonality of cyclogenesis in North America.

轨道改进中插值系数的计算

数值法精密定轨在多步法积分产生轨道和插值法计算观测量和偏导数中,需要反复迭代来完成对航天器的历元状态的微分修正.严格地说插值的使用是合理的,但是重复的插值系数计算,对于有限的计算机资源来说,是一种负担.一次性插值技术的应用,将有利于在轨道改进中涉及的观测时刻的逐个处理的内循环和完成内循环反复迭代的外循

Deconstructing public artopia: Situating public-art claims within practice

This paper problematises public artopia, in other words the collection of claims in academic literature concerning the allegedly physical-aesthetic, economic, social, and cultural-symbolic roles of art in urban public space. On the basis of interviews with public-art producers (artists, public officials, investors, and participating residents) in a flagship and a community-art project in Amsterdam, we analyse the situatedness of their public-art claims according to actors’ roles, geographical context, and time. The research suggests that public-art theory and policy suffer from three deficiencies. Theoretical claims about public-art and policy discourse feature, first, a failure to recognise different actors’ perspectives: claims fail to locate situated knowledges that are intrinsically (re)constituted by actors’ roles articulating with one another in time and space. Second is the lack of geographical contextuality: claims do not elaborate appropriately on distinct discourses about art projects’ spatial settings. Third is the lack of temporal perspective. Claims neglect the practice of public-art realisation: that is, the evolution of claims and claim coalitions over the time horizon of the art projects: preparation, implementation, and evaluation.     

金沙江岩画洛吉岩画点调查记录及初步研究

2011年11月,云南省文物考古研究所与澳大利亚格里菲斯大学合作,首次用国际通行的考古学方法对迪庆州香格里拉县洛吉乡的岩布洛、花岩和腰岩3个岩画点进行详细的测量、三维摄影、摄像和描述,首次发现了二维和三维艺术形式同时出现的现象。金沙江岩画是有绝对年代数据的中国最古老的岩画,不同于中国其他地区岩画的一个独特类群而与欧洲法国、西班牙旧石器时代的岩画类似。金沙江岩画是来源于史前文化交流还是趋同进化还需进一步的研究。

Museums and the market: Exploring Santa Fe

Private and public antiquities collections present disturbing parallels. What differentiates the art market and the museum? Modes of acquisition, at least in part; and the curatorial mandate to preserve, study, and display collections, however imperfectly applied. But there remain areas of troublesome confusion, illustrated by the historical relationship of museums and collectors in Santa Fe, New Mexico
