Channel modelling for indoor visible light communications
(Royal Society Publishing, 2020-04-17)
Visible light communication (VLC) allows the dual use of light-emitting diodes (LEDs) for wireless communication purposes in addition to their primary purpose of illumination. As in any other communication system, realistic ...
Matched pairs of m-invertible hopf quasigroups
(Institute of Mathematics, Academy of Sciences Moldova, 2020)
The matched pair theory (of groups) is studied for a class of quasigroups; namely, the m-inverse property loops. The theory is upgraded to the Hopf level, and the m-invertible Hopf quasigroups are introduced.
Progressive damage analyses of masonry buildings by dynamic analyses
(Springer International Publishing AG, 2020-08)
This study investigates the effects of prescribed damage on the walls of masonry buildings by experimental and numerical methods. Ambient vibration survey method was applied to an existing, two-story, unreinforced masonry ...
A stochastic risk-averse framework for blood donation appointment scheduling under uncertain donor arrivals
(Springer, 2020-12)
Blood is a key resource in all health care systems, usually drawn from voluntary donors. We focus on the operations management in blood collection centers, which is a key step to guarantee an adequate blood supply and a ...
