Characterisation of transient electromagnetic signals during fixed interference sources in tunnel structure

<abstract> <p>The detection effect of the transient electromagnetic method is ambiguous in engineering applications due to the existence of interference sources, so explaining the influence of these fixed interference sources on is crucial. In this paper, the response characterisation of transient electromagnetic signals of fixed interference sources are thoroughly investigated. First, the secondary field generated by these interference sources is analyzed, and a typical fixed interference source is calculated. Then, a sensitivity analysis of the transient electromagnetic response curve is carried out. Finally, the mathematical superposition method for multiple field sources is proposed and verified. The results illustrate that the transient electromagnetic response curve of uniform full-space surrounding rock with a single fixed interference source has an apparent lifting phenomenon in the middle stage and presents an approximate horizontal change rule at the late stage. The transient electromagnetic response curves of multiple field sources separately illustrate the response characterisation of different field sources at different time stages. These research results can provide a valuable reference for the on-site interpretation of detection signals.</p> </abstract>

A Theoretical Framework for Informal 3D Rendered Analysis of the Roman Lararium from Apollonia-Arsuf

Digital reconstruction and visualization of archaeological sites are beneficial not only for public edification and admiration, but they can also significantly contribute to the site interpretation process. By going beyond basic modeling scenarios, one can apply 3D analyses for accurately testing visibility and lighting parameters, among other aspects. Based on the results of these tests, further insights can be extrapolated about the lived experience of culturally specific ancient peoples. The case of a Roman “villa” at Apollonia-Arsuf in Israel presents the opportunity to apply these informal techniques to a household shrine, or niche-style lararium, found within the building in order to ascertain sightline visibility based on the architectural plan and visual impact as a result of artificial illumination from ceramic lamps. This paper also considers how photorealistic visualizations aid in phenomenological areas of research through sensory archaeology and sense of place, which in turn encourages reflection on the political, social, and religious meanings of the built environment. When we combine the power and diverse applications of 3D visualization technology with decades of research about Roman architecture, culture, religion, and social norms, the result is a step closer to recreating archaeological remnants and, in turn, understanding the ancient experience.

On-site natural heritage interpretation: an ecocritical reading

One of the most ubiquitous features of the official countryside is the proliferation of interpretation boards that inform and enhance our experience of the natural world. Writers, artists, performers and story tellers will often play an active role in this interpretation process. The products of heritage interpretation can be considered as cultural objects in their own right. In this chapter, William Welstead makes the case for an ecocritical eye to be turned towards the practice and products of heritage interpretation, which is big business whose practitioners have their own professional organisation. The chapter looks at how interpretive practice constructs a way of looking at the natural world, and shows how the narratives of interpretation are influenced by inputs from the creative arts. Further work might usefully seek to establish whether this is a two-way process in which the works studied by ecocritics have themselves been influenced by on-site interpretation narratives.

Quantitative and GIS-based archaeological analysis of the Late Roman rural settlement of Ács-Kovács-rétek

One of the biggest problems archaeologists face during interpretation is the fragmented and incomplete nature of the datasets often produced by field work. In most cases, the excavation of a whole site is not possible, and even the find material is so fragmented as to make their interpretation quite problematic. Such is the case of Ács-Kovács-rétek, a small Late Roman rural settlement, a part of which was excavated in 2009–2010. These excavations provided a very deep insight into the life of the village, but due to their limited scope, they still left a number of questions unanswered. For a more thorough interpretation of the site, we have to look at the find material and its spatial and chronological context from as many different angles as possible. Such analyses have to rely heavily on very detailed quantitative and GIS-based methods that can not only hold large amounts of very diverse information, but can also recombine this information for statistical and spatial analyses that can deepen our understanding of the site. The aim of this paper is to demonstrate the power of detailed quantitative databases and methods for site interpretation through the study of a Late Roman settlement, Ács-Kovács-rétek. During the course of this research a large number of attributes of the find material and the site itself were recorded in structured databases. Thanks to the rational structuring of this data, it could not only be statistically analyzed, but also compared to other sites as well, helping to solidify the timeframe in which the settlement was inhabited, and also uncovering several interesting patterns about its inhabitants. Furthermore, the combination of this data with spatial information even helped to recognize certain changes and spatial patterns within the settlement itself. By the end of my research, a clear picture emerged of this Late Roman village, showing a Romanized population living here from the end of the 3rd through the 4th century AD that not only had connections regionally, but also fit into a local rural landscape in the hinterlands of the \textit{Ripa Pannonica}.
