Dual polarized weather radars, radars that can transmit both horizontal (H) and vertical (V) polarized waves, are becoming more common in the world. Dual polarization is accomplished via fast alternate transmission of H and V polarization or simultaneous H and V polarization transmission. The simultaneous H and V transmit mode is becoming quite popular since a high power, costly, polarization s...

Simultaneous acquisition of dual-isotope SPECT data offers a number of advantages over separately acquired data; however, simultaneous acquisition can result in cross-contamination between isotopes. In this work we propose and evaluate two frameworks for iterative model-based compensation of cross-contamination in dual-isotope SPECT. The methods were applied to cardiac imaging with technetium-9...

We present an overview of the first combinatorial results for the so-called geometric RAC simultaneous drawing problem (or GRacSim drawing problem, for short), i.e., a combination of problems on geometric RAC drawings [3] and geometric simultaneous graph drawings [2]. According to this problem, we are given two planar graphs G1 = (V,E1) and G2 = (V,E2) that share a common vertex set but have di...
