Ground penetrating radar

, 1992
The widespread use of ground penetrating radar (GPR) with a mixture of success and failure has Led to a greater understanding of where GPR is likely to work and where it won't. The ability to quantitative/y predict and emulate the response of simple targets has been needed for some time and is now easily achieved with simple PC programs.

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

Archaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...

Influence of grain size, shape and compaction on georadar waves: example of an Aeolian dune

, 2012
Many Ground Penetrating Radar (GPR) profiles acquired in dry aeolian environment have shown good reflectivity inside present-day dunes. We show that the origin of this reflectivity is related to changes in grain size distribution, packing and/or grain ...

‘School is their whole world’: Teachers' perspectives on loneliness among children and adolescents from England and mainland China

British Educational Research Journal, EarlyView.
Abstract As front‐line observers and active participants in pupils' daily lives, teachers closely monitor pupils' social interactions, emotional states and behavioural changes. Their unique perspective enables them to detect problems in the social lives of their pupils that may not be immediately visible to peers, parents or mental health professionals.

Ground penetrating radar applied to subsurface culverts

Geo-spatial Information Science
The failures of culverts can result in water and soil loss in the surrounding subsurface, leading to collapses. In densely constructed urban areas, buried culverts are inaccessible and invisible, making Ground Penetrating Radar (GPR) inspection a widely ...

Numerical study of electromagnetic wave propagation characteristics in collapsed building for rescue radar applications

ETRI Journal, 2018
Since the Gyeongju earthquakes in 2016, there have been increased research interests in the areas of seismic design, building collapse, and rescue radar applications in Korea. Ground penetrating radar (GPR) is a nondestructive electromagnetic method that

The Tree of Life Synagogue Attack: A Terrorist Radicalization Assessment Protocol‐18 Examination of Pre‐Attack Warnings and Post‐Attack Contagion and Copycat Effects

Behavioral Sciences &the Law, EarlyView.
ABSTRACT This is a retrospective case study of an antisemitic lone actor terrorist who completed the deadliest attack against the Jewish community in American history. The analysis through the lens of the Terrorist Radicalization Assessment Protocol (TRAP‐18) finds that 72% of the warning indicators were present, including four proximal warning ...

DETERMINATION OF THE GROUND-WATER LEVEL BY MODERN NON-DISTRUCTIVE METHODS (GPR TECHNOLOGY) [PDF]

Aerul şi Apa: Componente ale Mediului, 2011
Determination of the ground-water level by modern non-dis¬tructive methods (ground-penetrating radar technology). Ground Penetrating Radar (GPR) is now a well-accepted geophysical technique, which unfortunately in our country its less used. Historically,
