Hexagonal quadrature amplitude modulation aided spatial modulation
(Ieee, 2019)
In this study, a new multiple-input multiple-output (MIMO) transmission scheme with energy-efficiency is proposed by combining spatial modulation (SM) and energy-efficient hexagonal quadrature amplitude modulation (HQAM) ...
Code-index modulation aided quadrature spatial modulation for high-rate MIMO systems
(Ieee-Inst Electrical Electronics Engineers Inc, 2019)
In this correspondence paper, a novel code-index modulation (CIM) aided quadrature spatial modulation (QSM) scheme, called CIM-QSM, is proposed for highly spectrum and energy efficient multiple-input multiple-output (MIMO) ...
Single steel strut mechanical testing: challenges and future research directions
(Taylor & Francis Ltd, 2019)
Open-cell stainless steel foams, composed of hollow struts, are excellent candidates for energy absorption and thermo-mechanical applications. The basic mechanical element responsible for the function of these foams is the ...
Foams of gray cast iron as efficient energy absorption structures: a feasibility study
(Wiley-V C H Verlag Gmbh, 2019)
Gray cast iron foams, were produced using a reticulated polyurethane by using a modified investment casting process. To evaluate the attributes of the produced micro-geometries, foam segments and single struts are investigated ...
