An Automatic Modal Identification Procedure for the Permanent Dynamic Monitoring of the Sanctuary of Vicoforte

ABSTRACT

The interest in automatic modal parameter extraction techniques has increased significantly in recent years because of the rising demand for Continuous Structural Health Monitoring (CSHM) of civil structures and infrastructures. The wider use of CSHM is related to its capability for early damage detection and therefore to its usefulness for planning maintenance and strengthening interventions. This article presents the main steps followed in creating a robust routine to run on an online basis the first-ever Continuous Vibration-Based Structural Health Monitoring (CVB-SHM) of a large masonry oval dome, i.e., the dome of the Regina Montis Regalis Basilica, also known as Sanctuary of Vicoforte. The procedure uses an output-only stochastic subspace identification method complemented by an automatic analysis applied to identification results, which are typically provided in terms of stabilization diagrams. In this study, the fully automatic procedure also includes a hierarchical clustering algorithm to separate authentic from spurious modes.     

Public game funding in the Nordic region

ABSTRACT

In this paper, we explore the policies related to support structures surrounding national game industries, with focus on the three Nordic countries Finland, Norway and Sweden, and investigate what kind of context the Nordic welfare state model has provided for game development. The three cases illustrate how Nordic welfare state measures have interacted with the games industry over time. While the political ideals have been fairly similar, our study demonstrates how the objectives and practical means of state engagement have differed significantly. We argue that although the three countries all have support schemes of which game companies can take advantage, there are significant differences in the degree to which each individual country has organized government interventions and support. While the Finnish state has treated game development as an endeavour in business development, the regional Nordic game program and the Norwegian state has developed a cultural policy that primarily aims to protect the cultural heritage. The Swedish state has not established a tailormade policy directed towards game development but has a broad spectrum of general policies for supporting research and business development. We suggest that future research should investigate how the public funding is structured and how discourses are formulated around appeals for more public funding for the games industry.

Identifying of buried archaeological remains with ground penetrating radar,polarized microscope and confocal Raman spectroscopy methods in ancient city of Nysa,Aydin – Turkey

The aim of this study was to image buried remains and appoint buried Hellenistic street system, and identify minerals and rock types of the ancient city of Nysa, one of the most important historical sites of Turkey. This study used polarized microscope and confocal Raman spectroscopy (CRS) ground penetrating radar (GPR) method, to identify the buried remains, rock types and minerals.     

Patterning in procurement of obsidian in Chaco Canyon and in Chaco-era communities in New Mexico as revealed by X-ray fluorescence

X-ray fluorescence analysis of obsidian artifacts from sites located in Chaco Canyon and from three Chaco-era communities in New Mexico permits determination of their geological origin. These source data are used to describe patterning in obsidian procurement in sites located in Chaco Canyon dating from A.D. 500–1150, and in a three non-Canyon communities occupied during the period of Chaco Canyon's regional prominence (ca. A.D. 875–1150). These data demonstrate that the most proximate sources generally dominate the sourced obsidian assemblages from sites of all periods, but also suggest differences in procurement patterning both over time and across space. Within Chaco Canyon, there is a notable shift from Mount Taylor obsidian to use of Jemez Mountains sources over time. These data also suggest that earlier analyses of obsidian from sites in Chaco Canyon misidentified some obsidian artifact sources; these new data indicate the central areas of disagreement and provide a revision of procurement patterning. In the Chaco-era communities located outside Chaco Canyon, procurement patterning diverges. The Blue J community shows an increase in use of the nearby Mount Taylor source over time. Two communities located toward the southern extent of the Chaco great house distribution reveal a markedly distinct procurement pattern, obtaining nearly all of their obsidian from southern sources largely unrepresented at Chaco Canyon. Combined, these data provide new insights into raw material procurement and artifact production at sites in Chaco Canyon, and in communities occupied during the Chaco Phenomenon, the period of the Canyon's greatest regional influence.     

试论殷墟花园庄东地卜辞的行款

殷墟花园庄东地卜辞的行款表面上看较为复杂,但实际上仍遵循着一定的规律。这种规律表现为:卜辞基本守兆,在卜兆上方由内向外契刻,至兆干后再沿兆干外侧下行。由于卜辞字数不同,有的未至兆干即止,有的刻至兆干下方后再内行或外行。此外,相关卜兆的数量与排列方式、卜甲上卜辞条数的多寡、卜甲上可供刻字的空间等因素也会影响到卜辞的行款。了解、掌握花园庄东地卜辞行款与卜兆之间的密切关系,将有助于进一步认识王卜辞与其它非王卜辞的行款规律,对深入探讨商代后期的占卜制度也有裨益。

社会主义市场经济中的中国税制改革

1992年,具有伟大历史意义的中国共产党第十二次全国代表大会确定了中国经济体制改革的目标是建立社会主义市场经济体制。为此,中国于1994年实施了新中国成立以来规模最大、范围最广、内容最深刻的一次税制改革。经过这次税制改革和9年来的逐步完善,中国已经初步建立了适应社会主义市场经济体制需要的税收制度,对于保证财政收入、加强宏观调控、深化改革、扩大开放、促进经济与社会的发展起到了重要的作用。回顾1992年以来中国税制改革、发展的情况,目的在于真实地反映11年来中国税制发展的历程和取得的成就,总结经验,为今后中国税制的进一步改革与发展提供借鉴。

我国GDS系统的发展现状及其对策分析

加入WTO后,我国航空领域中的信息、票务、服务等三大市场将逐渐放开,而国内航空和旅游业的信息技术和信息服务相对于发达国家还处在起步阶段,功能不健全,网络不发达,缺乏市场竞争力。如何从战略的高度尽快接受并引入新技术以完善中国的GDS系统,已变得十分迫切。
