Abstract. The 2020 underwater archaeological research in the inlet of Torre Santa Sabina – Baia dei Camerini (Municipality of Carovigno, Brindisi, Italy) represented the first phase of the pilot intervention of the Interreg Italia-Croatia UnderwaterMuse project. The project aims to enhance and make accessible the vast underwater heritage of the areas involved; this will be done by creating submerged archaeological parks and using virtual reality's narrative and communicative tools and platforms. During the 2020 campaign, different survey activities were carried out using several techniques and methodology to produce the area's multi-scale documentation. First of all, the entire stretch of coast was mapped with UASs (Uncrewed Aerial Systems) flights to reconstruct the coastal landscape in various phases. Furthermore, an underwater photogrammetric survey carried out by expert scuba divers has been achieved in the wreck's aft area (the site analyzed during the 2020 excavation activities). The fruitful synergy between the various actors involved and the support of the territory and the community has allowed the achievement of this campaign's objectives, preliminary to the broader and more articulated intervention foreseen for the following year.

This article discusses the results of archaeological and anthropological research concerning material remains of a prisoner of war camp in Czersk (Pomeranian province, Poland) (Kriegsgefangenenlager Czersk). In the first part, I sketch a broader historical context related to building and functioning of the camp in forests around Czersk between 1914–1919. After that, the role and meaning of  archaeological research on such type of archaeological sites are presented. In the third part, I focus on a very special category of the camp heritage which is called trench art. The last part of this paper is a case study where an assemblage of objects classified as trench art that was found at the camp is described and interpreted. This text aims at highlighting the value of such prisoners and camp’s heritage. Such material culture is a material memory of extraordinary prisoners’ creativity behind barbed wire. It makes one aware of how every piece of trash, rubbish was re-cycled during day-to-day life behind barbed wire.

BATTLING WATER: THE FRONTIERS OF ARCHAEOLOGICAL EXCAVATIONS AT BUTRINT (1928–2014)

The Impact

This article examines the impact of sea level (water table) on archaeological research at Butrint (Bouthrotos/Buthrotum) from 1928 to 2014. Rising relative sea levels over the past three thousand years have shaped the actions not only of its ancient inhabitants but also of its modern archaeologists, conditioning archaeological objectives, fieldwork and the interpretation of the archaeological record. Butrint's first archaeologist, Luigi M. Ugolini, considered groundwater to be a detriment to archaeological research at the site. Subsequent archaeologists have viewed it as the limit of excavation. Battling water at Butrint, archaeologists have shared a universal perception of groundwater as an enemy and thereby have overlooked one of Butrint's most important areas of archaeological research – its wetland and wet-site archaeology. The Roman Forum Excavations (RFE) Project undertook the first wet-site excavations at Butrint, reaching depths of up to four metres below the water table in stratigraphic excavations in the ancient urban centre. The results demonstrate that the ancient urban centre formed much later than is presently thought: the lower city emerged as dryland in the second half of the second century bc. Relative sea levels have increased since antiquity at many coastal regions in the Mediterranean, often submerging archaeological sites either partially or completely. Butrint is a case study that shows how sea level is inextricably tied to archaeological practice and interpretation at this major ancient Mediterranean seaport.

Present Case Study

In the last decades, geophysical methods such as magnetic survey have become a common technique for prospecting archaeological sites. At sub-Saharan archaeological sites, however, magnetic survey and correlated techniques never came into broad use and there are no signs for an immediate change of this situation. This paper examines the magnetic survey undertaken on the Nigerian site of Zilum, a settlement of the Gajiganna Culture (ca 1800-400 BC) located in the Chad Basin and dated to ca 600-400 BC. By means of the present case study, we demonstrate the significance of this particular type of investigation in yielding complementary data for understanding the character of prehistoric settlements. In conclusion, we point out that geophysical methods should play a more important role in modern archaeological field research, as they furnish a class of documentation not achievable by traditional survey and excavation methods, thus creating new perspectives for interpreting the past of African societies.

Unmanned aerial vehicles are currently the most used solution for cultural heritage in the field of close range and low altitude acquisitions. This work shows data acquired by multitemporal and multispectral aerial surveys in the archaeological site of San Vincenzo al Volturno (Molise, Italy). The site is one of the most important medieval archaeological sites in the world. It is a monastic settlement that was particularly rich during the early Middle Ages, and is famous for its two full-frescoed crypts which represent a milestone in the history of medieval art. Thanks to the use of multispectral aerial photography at different times of the year, an area not accessible to archaeological excavation has been investigated. To avoid redundancy of information and reduce the number of data to be analysed, a method based on spectral and radiometric enhancement techniques combined with a selective principal component analysis was used for the identification of useful information. The combination of already published archaeological data and new remote sensing discoveries, has allowed to better define the situation of the abbey during the building phases of the 8th/9th century and 11th century, confirming and adding new data to the assumptions made by archaeologists.

AbstractThe task of fault detection is crucial in modern chemical industries for improved product quality and process safety. In this regard, data-driven fault detection (FD) strategy based on independent component analysis (ICA) has gained attention since it improves monitoring by capturing non-gaussian features in the process data. However, presence of measurement noise in the process data degrades performance of the FD strategy since the noise masks important information. To enhance the monitoring under noisy environment, wavelet-based multi-scale filtering is integrated with the ICA model to yield a novel multi-scale Independent component analysis (MSICA) FD strategy. One of the challenges in multi-scale ICA modeling is to choose the optimum decomposition depth. A novel scheme based on ICA model parameter estimation at each depth is proposed in this paper to achieve this. The effectiveness of the proposed MSICA-based FD strategy is illustrated through three case studies, namely: dynamic multi-variate process, quadruple tank process and distillation column process. In each case study, the performance of the MSICA FD strategy is assessed for different noise levels by comparing it with the conventional FD strategies. The results indicate that the proposed MSICA FD strategy can enhance performance for higher levels of noise in the data since multi-scale wavelet-based filtering is able to de-noise and capture efficient information from noisy process data.
