Gamma-ray measurements of naturally occurring radioactive samples from Cyprus characteristic geological rocks
M. Tzortzis, H. Tsertos, S. Christofides +1
Using high-resolution gamma-ray spectroscopy, the terrestrial gamma radiation in all the predominant types of geological rock formations appearing in Cyprus was measured. Soil samp…
Indoor radon (Rn-222) concentration measurements in Cyprus using high-sensitivity portable detectors
T. Anastasiou, H. Tsertos, S. Christofides +1
Using high--sensitivity radon (Rn-222) portable detectors (passive electronic devices of the type RADIM3), the airborne Rn-222 concentration in the interior of various Cypriot buil…
Gamma radiation measurements and dose rates in commercially-used natural tiling rocks (granites)
M. Tzortzis, H. Tsertos, S. Christofides +1
The gamma radiation in samples of a variety of natural tiling rocks (granites) imported in Cyprus for use in the building industry was measured, employing high-resolution gamma-ray…
Modeling Complex Domains of Actions and Change
Antonis Kakas, Loizos Michael
This paper studies the problem of modeling complex domains of actions and change within high-level action description languages. We investigate two main issues of concern: (a) can…
The Cheeger constant of simply connected, solvable Lie groups
Norbert Peyerimhoff, Evangelia Samiou
We show that the Cheeger isoperimetric constant of a solvable simply connected Lie group with Lie algebra $\G$ is $h(G)=\max_{H\in\G,||H||=1} \tr(\ad (H))$.
