针对莫高窟在保护利用数据传输过程中出现的问题与发展趋势,提出了利用无线网络深度覆盖技术构建数据传输平台,解决莫高窟大型洞窟内保护利用数据无法传输的问题。为构建实用性强的传输平台,采取了如下措施。首先,针对莫高窟保护利用各项业务数据采集、传输模式、传输机制等各阶段特点,提出了基于无线网络深度覆盖技术构建数据传输试验平台的需求;其次,设计了试验平台构建方案,依据莫高窟洞窟分布与建筑形制确定了试验平台构建位置。结合莫高窟目前无线网络覆盖现状,通过选型分析确定了无线网络深度覆盖关键技术,并应用该技术构建试验平台;最后,对试验平台无线信号覆盖范围、信号强度、传输性能、安全性等进行验证,确保数据传输的完整性与连续性。此试验平台已运行一年有余,应用效果良好。  相似文献

Whale bone was used by Māori throughout New Zealand prehistory as an industrial resource for the manufacture of a range of artefacts. However, the selection of bone and the methods used to process it are poorly understood. This paper details the analysis of a southern right whale (Eubalaena australis) bone working floor that was excavated from a fifteenth‐century coastal fishing camp at Kahukura, on the southeast coast of New Zealand. The whale bone working floor assemblage, comprising a large quantity of debitage fragments, was used to reconstruct reduction methods and to determine the products being made at the site. Rib bones were the main element being worked, and were reduced longitudinally using a chipping technique. The intensive bone working assemblage at Kahukura represents the by‐products from primary processing. This stage focused on reducing the bones into workable portions so that they could be easily transported to another location, where they were likely further reduced into artefacts.

Excavations in 1988 revealed a stratigraphic sequence extending from the later Roman period to the twelfth century. Of particular interest and importance is a collection of Viking-Age metalwork which, with other material, sheds light on settlement in Carlisle before the arrival of the Normans in 1092.  相似文献

维摩诘题材是中国佛教美术中最为重要且常见的题材之一。早在佛教东渐之初的两汉时期,以维摩诘为主角的《维摩诘经》已经被介绍来中国,伴随经典的翻译传播,维摩诘所代表的融通世、出世间,注重理、行不二的大乘佛教理念在中国寻得了大众,特别是具有儒家传统而兼出世情怀的士大夫阶层的普遍认可,而经中表述的丰富多彩的情节与生动鲜明的形象更使得维摩诘成为远自魏晋以来,广及绘画、雕塑以及诗歌、戏剧、音乐等各个艺术门类的重要题材[1],这使得它在中国文化发展史上的作用,甚至超出了其于宗教范畴内的意义。本文拟就维摩诘作为美术题材的发生、发展及其通例表现形式的宗教蕴意作通览性的考察与探究。  相似文献

This article seeks to further our knowledge of the university campus by focusing on one particular aspect of most UK campuses: the students’ union. UK students’ unions have rarely been the subject of scholarly attention, despite them now occupying an important place within the higher education landscape. Nevertheless, in this paper we draw on a UK-wide study of students’ unions to explore, firstly, the role played by the buildings of the students’ union and, secondly, the ways in which aspects of the university’s campus influence union activity. We pay particular attention to the expansion of the university campus, in many institutions, from a single site to multiple sites, both within the UK and overseas. We contend that a focus on the materiality of the students’ union and the level of union activity (or inactivity) across various campus spaces can illustrate the values, ideologies and power relations that dominate contemporary British higher education.  相似文献

This essay explores the impact of governance on the Chinese religious landscape during the early years of the People’s Republic of China (PRC) through a case study of the Young Buddhist Association (YBA) of Shanghai. Despite the official atheist ideology of the Chinese Communist Party, during this era of New Democracy the YBA experienced Communist governance in practice as a process of political incorporation rather than coercive eradication. As its Buddhist youth movement not only survived the Communist takeover in 1949 but gained momentum well into the 1950s, the YBA was propelled to the forefront of the Buddhist community in Shanghai and became the most active and influential grassroots Buddhist organization in the early PRC. The case of the YBA demonstrates that incorporation into the new political order of the 1950s had transformative effects on the spatial construction, identity formation, and social dynamics of religious communities that cannot be reduced to steps toward their eventual elimination during the Cultural Revolution.  相似文献

African clothing industries have declined since the implementation of economic liberalization policies in the early 1980s whilst used‐clothing imports to Africa have increased. The general effects of economic liberalization on African clothing industries are well documented, although little research has been conducted on the particular impact of increased imports of second‐hand clothes on the local manufacturing sectors. Whether these two processes are causally related is difficult to determine due to limitations in official data sets. In this article, the used‐clothing trade is explored in detail and a broad range of cultural and local economic processes are investigated. Trends such as declining local purchasing power and the opening of African markets to cheap new clothing imports, as well as imports of used‐clothing, are examined, along with the converse boost to African clothing export production resulting from preferential trade agreements in the 2000s. With respect to the differential legal and illegal imports of second‐hand clothing to selected African countries, it is demonstrated that official trade data sets often fail to capture the nuances of contemporary social and economic processes.  相似文献

Absenteeism on roll call votes in the U.S. House decreased just prior to events of the early 1970s, thus suggesting that the two events are related. Changes during the early 1970s increased the number, the visibility and the pubic accessibility of recorded legislator's decisions. With relevant political actors having easier access to more legislator's decisions, lawmakers have less room to deviate from what they perceive to be the electorally tenable position. While good roll call attendance rates are now the norm, this is even more so in cases of high visibility votes, i.e., conflictual votes and votes of stated presidential concern. Nonetheless, the use of strategic absenteeism by politically conflicted, southern Democrats seems to endure.  相似文献
