ABSTRACT This paper presents the results of a pilot study that combines findings from satellite remote sensing analyses and an intensive interdisciplinary survey conducted in November 2021 on kurgans along Kurekçay Valley, western Azerbaijan. Through integration various methods, including historical contemporary aerial imagery analysis, topographic mapping geophysical prospections, this research remotely maps quantifies density, size, morphology distribution burial mounds area. Unlike...
Groundwater acts as a critical link between onshore and offshore environments, connecting freshwater systems to saline oceans.  With 40% of the world's population residing along coastlines, understanding coastal groundwater reserves is paramount. One open question involves vital role submarine springs in global hydrology, how distribution flux can be better constrained across coastline predict both discharge into ocean saltwater inflow aquifers. Especially urban areas pose unique...
ABSTRACT Electrical resistivity tomography (ERT) is nowadays widely used in archaeological prospection. This study deals with an approach to make ERT more time‐efficient and flexible. It based on calculating arbitrary 4‐point configurations by superposition of multiple pole–pole measurements. Investigating its applicability for purposes the objective this work. To do so, a synthetic case are conducted gain insights into effects nonideal field conditions, noise susceptibility other challenges...
We present a case study of multi-coil frequency-domain electromagnetic (FD-EMI) prospection wooden ship wreckage from the 17th century. The is buried in sandbar German part tidal flat area North Sea. Furthermore, was excavated advance and covered again after investigation. This ground truthing background position makes it unique investigation object to test feasibility FD-EMI for prospecting archaeological objects high conductive sediments areas. Our results reveal shape terms conductivity...
We consider the discrete time stopping problem \[ V(t,x) = \sup _{\tau }\mathbb {E}_{(t,x)}g(\tau , X_{\tau }), \] where $X$ is a random walk. It well known that value function $V$ in general not smooth on boundary of continuation set $\partial C$. show under some conditions interior $C$ either. Even more, additional we differentiable dense subset $C$. As guiding example Chow-Robbins game. give evidence C$ and convex, game other examples.
<p>The ancient city Miletus is located at the Mediterranean coast of present Turkey. Its former geographical position on a land tongue in Gulf with four bays, which can be used as harbours, made place great economical interest. During last decades, several archaeological and geophysical investigations were carried out to reconstruct cityscape Miletus.<br>In 2018, geoelectrical measurements revealed high-resistive anomaly near western market place. The aim...
Abstract The Chow–Robbins game is a classical, still partly unsolved, stopping problem introduced by Chow and Robbins in 1965. You repeatedly toss fair coin. After each toss, you decide whether take the fraction of heads up to now as payoff, otherwise continue. As more general this reads $V(n,x) = \sup_{\tau }\mathbb{E} \left [ \frac{x + S_\tau}{n+\tau}\right]$ , where S random walk. We give tight upper bound for V when has sub-Gaussian increments using analogous time-continuous with...
Summary Underground heat storages are one out of several possibilities to store energy on a large scale. Using the subsoil as such storage, it is necessary monitor expansion temperature field and look for possible leakages. In this study, geothermal experiments carried an idealised meso-scale sand pit named "GeoModel". The sample heated up cooled down by circulating hot cold water in Borehole Heat Exchanger (BHE). Simultaneously, half body monitored borehole electrical resistivity tomography...
