3D surveys of archaeological elements and the construction of virtual models enable us to reconstruct historical sites. They provide useful data to select specific building processes.Photogrammetry and Terrestrial Laser Scanning (TLS) are the most common techniques to obtain synthetically heritage models. These techniques provide massive data which can only be managed by replacing them by primitive shapes, thereby obtaining more simple models and the explicit geometry of the element. Statistical and robust methods are used for this substitution, thereby avoiding the common errors due to measuring. Of these methods, the most widely used are the least-median-of-squares (LMedS) and the RANSAC method.Another computation method consists in recursive processes based on evolutive-type algorithms to adjust the model to the data captured.This paper describes two surface computation methodologies to determine the modelling of a column shaft located in temple G of the archaeological park of Selinunte (Sicily). 相似文献

An upper molar of a small bat, here described from an early Miocene freshwater lime-stone deposit at Riversleigh, northwestern Queensland, is the oldest record in Australia of the microchiropteran family Vespertilionidae. The new taxon is referred to the cosmopolitan genus Leuconoe, but it does not appear to be closely related to the two extant Australian species of this genus. 相似文献

Cross‐border residential mobility (CBRM) has so far largely been approached from a transnational perspective. However, recent developments in border studies and transnationalism give rise to certain doubts. While border studies have come to include mental borders next to physical borderlands, transnationalism today refers not just to cross‐border movements but also to identities trans‐cending the national. But border studies have shown that the increased crossing of borders is not necessarily coupled with their diminished significance. CBRM is a particularly interesting phenomenon as it entails the continuous crossing of a physical border, but the question is whether it also implies the erosion of mental borders and the emergence of transnational ties. While drawing on experiences from parallel cases, my study focuses on Poles from Szczecin moving just across the boundary to Vorpommern, Germany. Some are integrating there, but their large majority appears to carry on with everyday life in Poland as before moving. This settlement has triggered considerable resentment among local Germans, who as a reaction mark the borderland discursively and physically. As my survey shows, while both groups regularly cross the physical border, many even among the cross‐border residents consider it as a necessary dividing line or prefer cooperation to be reserved to some activities. Hence, unlike longdistance migration leading either to diaspora identities or to gradual dissolution in the majority culture, CBRM appears as a specific form of international migration where the physical proximity allows such intensive links with the country of origin that transnational effects are mitigated. 相似文献

This paper documents court‐imposed bail and sentencing conditions with spatial dimensions, such as red zones, no contact conditions, curfews and prohibitions to demonstrate, issued in the context of criminal proceedings. These conditional orders, which are growing in importance and have a significant impact on the lives of marginalized groups of people, have not received the attention they deserve in the literature. As opposed to better publicized forms of spatial regulation such as legislation or policing strategies, these conditional orders are a distinctive form of spatial tactic that rely on ancient and routinized rules of criminal procedure and the practices of the courts. In order to understand this spatial tactic, and its impact on marginalized people's rights and uses of spaces, we argue that it is necessary to pay attention to the legal rationalities, knowledge and practices that sustain them. 相似文献

Beginning with the first travelogues of the late 1890s, the film and tourism industries collaborated both directly and indirectly to shape representations of North America’s western landscape and its people. These non-narrative motion pictures intersected with the rise of mass consumerism, modern tourism, the forces of imperialism and colonialism, as well as industrialized forms of transportation. In particular, railroad travel films from the Canadian Pacific Railway Company and the Northern Pacific Railway Company transformed motion-picture goers into armchair tourists, exposing audiences to the scenic wonders of the West. These transcontinental railroads, themselves products of nation-building initiatives, competed against one another to increase passenger traffic by marketing the sublime and often overlapping landscapes of the American and Canadian Wests as potent nationalist and unifying symbols that heralded each country’s uniqueness. 相似文献
