This paper shows how visual analytics methodology can be used to facilitate interpretation of multi‐temporal thermographic imagery for the purpose of restoration of cultural heritage. We explore thermographic data in a visual environment from the unifying spatio‐temporal perspective in an attempt to identify spatial and spatio‐temporal patterns that could provide information about the structure and the level of decay of the material, and the presence of other physical phenomena in the wall. The approach is tested on a thermographic dataset captured on the façade of a Romanesque building from the 13th century—the Cathedral in Matera (Italy). 相似文献

This paper's primary objective is to contribute to the ‘never‐ending story’ of estimating irregular migration. It presents an attempt to develop an empirically based approach/technique for estimating the size of an irregular migrant population, or more specifically of irregularly residing immigrants within the city of Prague. A pilot study, based on discovering the actual number of immigrants residing in selected localities, was conducted via observations and inquiries to local residents, and, subsequently, by comparing these numbers with local official statistics concerning inhabitants. Getting to know the types of built environment in selected localities aided in efforts to extrapolate an estimate for the entire city. Moreover, the spatial distribution of irregular migrants within a city is discussed. 相似文献

In 1969, a few short months after the Warsaw Pact invasion of Czechoslovakia, Sergei I. Prasolov, advisor to the Soviet Ambassador in Prague, informed František Šorm, President of the Czechoslovak Academy of Sciences, at a formal meeting that he welcomed Šorm's suggestion to intensify scientific exchange between Czechoslovakia and the Soviet Union. Šorm politely declined this offer. Behind the veneer of diplomatic courtesy on the part of both actors, a real drama was taking place. Šorm and the Czechoslovak Academy of Sciences had actually never formulated such a request. To the contrary, since the late 1950s the academy had repeatedly pointed out that the Soviets were incapable of coordinating scientific activities in the Eastern Bloc. The Soviet system of academic cooperation within the Eastern Bloc had already begun to collapse after the Geneva Summit of 1955, where the Soviets opened the door to international collaboration across the Iron Curtain. Yet it was only in the late 1960s that the Soviets realized that while they dominated large-scale international collaboration, they had lost control of internal developments within the Eastern Bloc. 相似文献

The invention of optical instruments showed that the extent of human experience is not eternal and natural but contingent – it can change, depending on the availability and performance of optical instruments over time. This knowledge of the temporal variability of empirical knowledge led to changes in the methodology and epistemology of early modern natural philosophy. In this article, I focus mainly on three aspects of this process. Firstly, optical technique has shown that nature cannot be examined by an isolated individual. Natural philosophy must be a collective activity with institutional support. Secondly, use of optical instruments led to an understanding of the relativity of contemporary natural philosophy, no longer understood as the culmination of preceding development. The present state of natural philosophy becomes a transient stage in a longer development. Thirdly, telescopes and microscopes contributed to the formation of an idea of unending progress. 相似文献

This comparative study on the urban re-imagineering performed through large-scale urban refurbishment focuses on the specific post-socialist and post-conflict contexts of former Yugoslavia. Through the analysis of legislative and planning documents, expert interviews, reports, and media coverage, this study shows how initiatives for the implementation of grandiloquent urban megaprojects (UMP) in the capital cities of Serbia and Macedonia became extreme examples of national image reconstruction, carried out through autocratic state-led interventions that disregarded public input. The two main insights that the study provides classify these cases as rather particular in the European framework. First, the national governments have played a decisive role in conceiving entrepreneurial strategies for national rebranding through urban re-imagineering of its capital cities. Second, this politically orchestrated processes advanced through non-transparent decision-making, in spite of the rising opposition by the civic alliances. In conclusion, autocratic implementation of UMPs in the urban contexts of the Yugoslavian successor states played out much more forcefully, overriding the imperative to satisfy genuine public interest. 相似文献

The aim of this article is to explore the complexity of the online sex trade and work by analysing sexuality-related commercial websites, with reference to three European states, France, Greece and Slovenia. The article compares websites in each specific sociocultural context, in order to provide insights into the various types of networks and services that emerge, and to explore how they operate, how they communicate and how sex is being merchandised. We have conducted a two-tier analysis: The first part discusses results of a quantitative macro-analysis exploring 149 websites, while the second part is a micro-analysis analysing the visualisation of egocentric network of three selected websites. The focus is on understanding how gender relations develop in digital environment and how within cyberspace sectorial and national divides are dealt with. While there is evidence to suggest that in some sectors the Internet has opened avenues for sex workers to work independently of the control networks, there are also many forms of exploitation that arise from new media. We observe that sex commerce online is not particularly attentive to the agency of sex workers but is, to the contrary, oriented to provide opportunities and a forum for businessmen and clients. 相似文献

There are several hundred recorded Early Upper Palaeolithic sites in Moravia, most of which are surface sites. The majority were exposed by agricultural plowing and subsequently discovered by pedestrian surveys whereas most of the stratified sites were found accidentally. Numerous unsystematic attempts in the past to find stratified remnants of sites disturbed by plowing have been unsuccessful. Here we present a methodology for locating stratified Early Upper Palaeolithic cultural contexts based on distribution of surface scatters. This involves pedestrian surveys guided by background research. All Palaeolithic artifacts were recorded using a handheld GPS with particular attention to calcium carbonate crust on artifact surfaces, which can be indicators of nearby stratified deposits. Exploratory test pits were then excavated followed by systematic excavations if the potential for stratified cultural deposits was deemed high.
Using this technique, we have discovered 11 new stratified Early Upper Palaeolithic sites. 相似文献
