Current Events

ABSTRACT This article shows how to record current events from an archaeological perspective. With a case study from the COVID-19 pandemic in Norway, we provide accessible tools to document broad spatial and behavioral patterns through material culture as they emerge. Stressing the importance of ethical engagement with contemporary subjects, we adapt archaeological field methods—including geolocation, photography, and three-dimensional modeling—to analyze the changing relationships between materiality and human sociality through the crisis. Integrating data from four contributors, we suggest that this workflow may engage broader publics as anthropological data collectors to describe unexpected social phenomena. Contemporary archaeological perspectives, deployed in rapid response, provide alternative readings on the development of current events. In the presented case, we suggest that local ways of coping with the pandemic may be overshadowed by the materiality of large-scale corporate and state response.

Large Scale Survey

<p><strong>Abstract.</strong> The following research aims to exploit the low-cost technologies, for the survey and mapping of historical archaeology in the Roman context. The main purposes of the research is to implement a large-scale survey campaign to understand the geometry and the materiality of the artefacts examined. Three-dimensional survey from photography, allows an immediate mapping of the materiality, of the degradation and of the architectural elements characteristic of the architecture in question. From the model it is possible to obtain an image that is faithful to the reality that can be the basis for developments in many disciplines such as, for example, in the restoration project, for the material analysis and the mapping of the degradation. The applications for this type of mapping are numerous, one of those proposed in this research concerns the virtual musealisation of historical artifacts. More and more in recent years, museums are exploiting the capabilities of three-dimensional modeling software of architectural elements to interactively convey architectural elements. A methodology of work that in recent archaeological excavations is not based solely on the didactic divulgation of the history of a place, but during the excavation phase on the mapping and cataloging of uncovered finds.</p>

The Difference

Abstract In this study, the use of three-dimensional modeling method was tested in taking some body measurements in camels with a practical method and was compared with other measurement methods. As the animal material of the study, 12 single humped dromedary female camels and 14 double humped Camelus dromedarius X Camelus bactrianus: F1 male camels, totally 26 camels, were used in three camel farms in Incirliova district of Aydın province. The body measurements taken from each animal by using different three methods, namely by Manuel Method (MM), by Photography Method (PM), and by Three Dimensional Modeling Method (3D) were the Cidago Height (CH), the Back Height (BH), the Rump Height (RH), the Body Length (BL), the Brisket Height (BRH), the Abdominal Height (AH), the Shoulder Width (SW) and the Rump Width (RW) and these values were compared with each other. As a result of this study, the mean values of MM and 3D measurement values were very close to each other and the difference between them was found to be statistically insignificant. (P<0.05). The difference between the means of PM and MM/3D measurement values was found to be significant. (P <0.05). In the measurements taken by MM, 3D, PM methods in male camels, the values obtained by MM and 3D methods for CH, BH, RH, BRH, AH, BL, and SW were very close to each other and the differences between them were found insignificant statistically (p < 0.05). On the determined regression graph, a linear was found between MM and 3D measurement values. As a result of this study, it has been determined that the 3D modeling method can be used as a remote and more practical method in determining the morphological features of large-scale animals such as camels more reliably, more easily and more practically.

To study the agitating effect of submersible mixers in a square sewage treatment pool, the three-dimensional modeling Pro/E software was adopted to establish the physical model. The large-scale computational fluid dynamics software FLUENT6.3 was used, and the large-scale software ICEM was selected to build an unstructured tetrahedron grid of the sewage treatment pool. Next, the sewage treatment pool was numerically simulated by RNG k-ε turbulent model and move coordinate system technology. The macrofluid field and the flow field distribution of each section were analyzed to observe the efficiency of each submersible mixer. The average velocity of the fluid and the stirring volume were studied simultaneously. Results show that, under the action of three mixers, fluid of the sewage pool forms a continuous circulating water flow. The fluid is mixed adequately. The average velocity of fluid in the pool is at around 0.3 m/s, and the fluid mixing area in the pool is more than 90%, which is in agreement with the working requirements. Consequently, it can provide a reference basis for the practical engineering application of submersible mixers by using this method.

3D Digitization

Techniques for the three-dimensional digitization of tangible heritage are continuously updated, as regards active and passive sensors, data acquisition approaches, implemented algorithms and employed computational systems. These developments enable higher automation and processing velocities, increased accuracy, and precision for digitizing heritage assets. For large-scale applications, as for investigations on ancient remains, heritage objects, or architectural details, scanning and image-based modeling approaches have prevailed, due to reduced costs and processing durations, fast acquisition, and the reproducibility of workflows. This paper presents an updated metric comparison of common heritage digitization approaches, providing a thorough examination of sensors, capturing workflows, processing parameters involved, metric and radiometric results produced. A variety of photogrammetric software were evaluated (both commercial and open sourced), as well as photo-capturing equipment of various characteristics and prices, and scanners employing different technologies. The experimentations were performed on case studies of different geometrical and surface characteristics to thoroughly assess the implemented three-dimensional modeling pipelines.

The paper presents the processing of 2 cluster pumpings from imperfect wells inside a low-permeable rock mass. The processing was done using graphical-analytical method with three-dimensional modeling in GMS 10.4 software. The results obtained were analyzed and the interpretation methods of groundwater inflow testing (GIT) were compared. The paper identifies common patterns in the model GIT interpretation with some assumptions made on how to improve the processing of their results.
