Beamforming for Rotated 3D Multipanel Array Structures for 5G NR MIMO Transmission by Hyukjun Lee, Wonjae Ryu, Wonjin Sung, Jonghyun Park

“…In this paper, we propose an array structure to transmit signals over the three-dimensional (3D) space in an isotropic fashion for all types of UEs in ground, aerial, and high-rise building locations, by employing panels on surfaces of a polyhedron. We further derive exact beamforming equations for the proposed array and show the resulting beams provide improved receiver performance over the exiting conventional beamforming. …”

Enhancing the flexural performance of lightweight concrete slabs with CFRP Sheets: an experimental analysis by Mustafa J. Khadim, Abdulkhalik J. Abdulridha

“…Tested one specimen with no strengthening and another with CFRP sheet strengthening and repaired the rest with a single layer of CFRP at damage ratios of 50%, 60%, or 70% of the ultimate load, consciously making each slab crack under bending loads while keeping the exact measurements. As to the experiment findings, the ultimate load capacity increased by 30.3% at the strengthened specimen, 17.7% at the 50% damage level, 12.6% at the 60% damage level, and 10.9% at the 70% damage level. …”
