Multidisciplinary Approach to Identifying Early Mediaeval Gates: A Case Study of the Břeclav–Pohansko Stronghold

Archaeological Prospection, EarlyView.
ABSTRACT This study presents a comprehensive approach to verifying a presumed western gate at Pohansko by integrating nondestructive geophysical methods (ERT, magnetometry and core prospection) with traditional archaeological excavation. The identification and characterization of gates by nondestructive methods within early mediaeval fortified sites ...

Three‐Dimensional Electrical Resistivity Tomography Schemes Optimized for Imaging Wall Foundations

Archaeological Prospection, EarlyView.
ABSTRACT This paper describes the application of three‐dimensional electrical resistivity tomography (ERT) in urban environments to detect wall foundations or similar structures. In this study, a specific measurement strategy based on optimized 3D measurement arrays with surface electrodes is proposed and tested.

Integrated Electromagnetic Mapping Through K‐Means to Improve Identification of Areas of Archaeological Interest

Archaeological Prospection, EarlyView.
ABSTRACT This study proposes a procedure to improve the interpretation of data from the Frequency Domain ElectroMagnetic method (FDEM), a geophysical technique with high benefit–cost ratios in archaeology. This method enables the simultaneous analysis of electrical and magnetic properties of the investigated medium, providing data as in‐phase and out ...

Usage of the term provenance in LIS literature: An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Provenance is the story of how something has come to be. In this paper, we provide a systematic literature review to categorize the various notions of provenance in Information Sciences. The goal of this review is to paint a broader picture of the multiple uses of provenance at play and to enhance our understanding of the importance of ...
