This paper presents a new qualitative method for the use of pXRF in archaeological research.A bulk, multi-elemental approach applies a non-destructive survey technique to the copper-alloy objects recovered in a Roman period tarand cemetery, in north-east Estonia.The aim is to explore the chronological development of the cemetery by BLOCK comparing
Soil nailing is a prevalent and cost-effective technique employed to reinforce and enhance the stability of precarious natural or cut slopes; however, its application as a primary support system to prevent collapses or cave-ins during foundation excavation could be more frequent.To better understand the behavior of such a support system, this study
Abstract Background To compare two approaches to the statistical analysis of the relationship between the baseline incidence of adverse events and the effect of medical emergency teams (METs).Methods Using data from a cluster randomized controlled trial (the MERIT study), we analysed the relationship between the baseline incidence of adverse events
Abstract The petrol truck routing problem is an important part of the petrol supply chain.This study focuses on determining routes for distributing petrol products from a depot to petrol stations with the objective of minimizing the total travel cost and the fixed cost required to use the trucks.We propose a mathematical model that considers petrol
Despite the wide variety of studies and research on mobile robot systems, performance metrics are not often examined.This makes difficult to establish an objective comparison of achievements.In this paper, the navigation of an autonomous mobile robot is evaluated.Several metrics are STICKERS described.These metrics, collectively, provide an indicat
