基于海量点云数据的大雁塔三维重建

古建筑三维重建已成为历史遗迹保护与修复的重要内容。为了探讨三维激光扫描数据的获取流程、数据处理方法,以三维激光扫描获取的大雁塔海量点云数据为例,研究了古建筑三维重建中点云数据获取与处理的详细过程。联合Cyclone、AutoCAD和3D-Max软件的优点构建了大雁塔真实的横面、剖面、立面模型,其中重点研究了海量点云数据在Cyclone软件中分块建模的方法。结果表明:将拼接好的大雁塔海量点云数据分块建模,不仅加快了数据处理的速度,而且符合精度要求。在点云数据拼接时采用标靶拼接和同名点拼接相结合及测站间两两拼接之后再整体拟合平差的方法,减少了拼接中的误差,使每站拼接误差都不超过3cm。在建模过程中的墙体拟合是上万个点云经过平差计算得到,精度高达2mm。最后在3D-Max软件中组合、渲染和贴图,真实地构建了大雁塔三维立体模型。为古建筑数字化存档和后期的修缮工作提供了重要的依据。     

Brutalism Redux: Relational Monumentality and the Urban Politics of Brutalist Architecture

Brutalism is an architectural form that is experiencing somewhat of a revival of late. This revival focuses almost purely on its aesthetics, but there is an ethical dimension to Brutalism that often gets overlooked in these narratives. This paper therefore reanalyses the original concepts and ethics of brutalist architecture with a reaffirmation of the original triumvirate of brutalist ethics as articulated by Raynar Banham as monumentality, structural honesty and materials “as found”. The paper then articulates these through the literature on architectural affect to argue that brutalist ethics are continually “enacted” via a relational monumentality that brings the building and its inhabitants together in the practice of inhabitation. Using the case study of Robin Hood Gardens in London, the paper posits that a “brutalist politics” comes into light that can help catalyse a broader critique of contemporary neoliberalism.     

Magnetic Gradient Survey of the Marpole Period Dionisio Point (DgRv-003) Plankhouse Village,Northwest Coast of North America

Architectural reconstructions of plankhouses are central to the study of household and community organization on the Northwest Coast of North America. However, the sample of substantially excavated houses is constrained by their size, stratigraphic complexity, and typically limited surface expression. We present the results of a magnetic gradiometry survey of the Dionisio Point site (DgRv-003) village, occupied ca. a.d. 500–700 on the coast of British Columbia, Canada. Survey of four house platforms reveals patterning of magnetic anomalies consistent with the structure of shed-roof houses, a design recorded ethnographically and identified archaeologically at the site. These results suggest a consistent pattern of spatial and, potentially, social organization of the households. The similarity of patterns suggests that magnetometry may be useful for guiding plankhouse excavations elsewhere on the Northwest Coast, providing a means for expanding our knowledge of houses without relying solely on traditional excavation methods.     

Reading “wrecks of history” and the Harley family narrative

During the English civil wars, many elite families faced the destruction of the buildings, monuments, and movables that had served for centuries as testaments to their social standing. The Harleys of Brampton Bryan in Herefordshire faced just this situation after their estate was demolished during a Royalist siege in 1644. While the family had ample cause to lament, this study reveals that destruction could also be framed as a generative force. In this framework, the broken artefact works in multiple ways, recalling the intact pre-war family while simultaneously attesting to its suffering and sacrifice. As the Harleys and those close to them wrote about loss and destruction, they evoke the family’s ancient prestige and re-frame loss in a way that lays the groundwork for local reconciliation and the success of the Harley line. Out of the ruins of their lives, the Harleys are re-created as a godly, genteel family.     

Geochemical Methods for Sourcing Lava Paving Stones from the Roman Roads of Central Italy

This paper documents the results of in situ analysis of 306 lava paving stones and 74 possible source rocks using pXRF. Data were collected from sites both in the city of Rome—on major roads beyond the city (including the Viae Flaminia, Cassia, Clodia, Praenestina and Appia)—and in the city of Ostia. Comparison of the pXRF data with lava compositional data from the geological literature allows broad identification of possible sources. The results point to quite distinctive patterns of exploitation for the city of Rome and Ostia, utilizing the Alban Hills lava flows, and the roads of the middle Tiber Valley, drawing on lava flows associated with the Vico and Sabatini volcanoes. The results show the potential of pXRF to produce data to elucidate the exploitation of lava flows for paving the Roman roads.     

Secularisation,anticlericalism and cremation within Italian cemeteries of the nineteenth century

This article examines the monumental cemeteries of nineteenth-century Italy with regard to their role as platforms for the tensions between Church and state. In that burial grounds were publically owned yet administered by the clergy, they represented a space where conflicts between secular and clerical powers might be played out – conflicts that reached a peak in the final decades of the Ottocento following the annexation of the Papal State to unified Italy. Particular attention is given to the adoption of cremation as a practice that was advocated by anticlerical, liberal and radical factions in opposition to the Catholic Church. That opposition was manifested in the design and layout of Italian burial grounds and in construction of new crematoria.     

L'urne et le pot de chambre

Résumé  En 1931, Ludwig Wittgenstein a identifié l'architecte et le critique culturel Adolf Loos comme une des dix personnes qui ont exercé la plus grande influence sur son développement intellectuel. Dans cet article est examinée l'influence de Loos sur Wittgenstein, en particulier son importance dans le projet de Wittgenstein pour la maison de sa sœur, ainsi que celle exercée sur les idées concernant la langue et l'éthique exprimées dans leTractacus. In 1931, Ludwig Wittgenstein identified the architect and cultural critic Adolf Loos as one of the ten people who had exerted the greatest influence on his intellectual development. In this article, I examine Loos's influence on Wittgenstein's design for his sister's house and also on the ideas about language and ethics set out by Wittgenstein in theTractatus. JohnHyman, né en 1960, estfellow au Queen's College d'Oxford. Il a publié de nombreux articles concernant l'épistémologie, la philosophie de l'esprit, l'esthétique et la philosophie de Wittgenstein. Son prochain livre, intituléThe Objective Eye. Colour, form and reality in the theory of art (L'Œil objectif. La couleur, la forme et la réalité dans la théorie de l'art), sera publié par les Presses de l'université de Chicago en 2006.     

抗战时期陕甘宁边区的国民教育

陕甘宁边区的教育经历了曲折的探索过程,从旧教育模式到创立自己的教育模式,由强迫教育到尊重群众的自愿与需要,由包办到民办公助,形成了具有鲜明时代特色的教育体制。、国民教育培养出的毕业生成为社会的有用之才,提高了陕甘宁边区文化程度,培养了大量专门人才。抗战时期陕甘宁边区的教育从抗战的环境和边区的实际出发,坚持教育同抗战、同社会、同生产劳动相结合的方针,为抗战培养人才,消除了群众中的文盲、迷信、不卫生的习惯,解决了群众生产和生活中的实际问题,既推动了边区教育事业的发展,也但排了边区经济、社会的进步,为抗战作出了重要贡献。     

The Materiality of Social Power: The Artifact-Acquisition Perspective

This paper explores the materiality of social power relationally through study of social interactions with artifacts. Specifically, it is argued that acquisition of an artifact instantiates social power by imposing interactions on groups taking part in that artifact's life-history activities. We introduce the “performance-preference matrix,” an analytic tool for systematically studying the effects of such acquisition events on activity groups. The use of the performance-preference matrix is illustrated through an example: the acquisition of electric-arc lights for lighthouses in the 19th century. Suggestions are offered for analyzing culture-contact situations and for handling singularized artifacts such as heirlooms and monuments.

客观世界与文本世界的交锋--对新理论形态的马克思主义历史观评论的评论

蒋大椿先生提出的“唯物辩证的以实践为基础的系统史观”．在马克思主义历史观发展史上．是一种全新理论形态的历史观。无论是对于马克思主义历史观的发展,还是对于新世纪中国历史学的发展来说,它都具有重要的理论价值和现实意义。但是,由于评论者悬置客观实在的现实社会和历史,沉溺于马克思恩格斯文本建构起来的文本世界,加上评论者和蒋大椿先生之间在探索的问题、言说的平台和所处思想时段等方面的差距,因此,他们没有能够发现蒋先生的真问题和《思潮与发展》一文所具有的理论价值与现实意义。综览目前公开的评论,只能说这是一场极不相称的客观世界与文本世界之间的交锋。
