Performance of OFDM-based adaptive visible light communications
In this paper, we investigate the performance of a direct current biased optical orthogonal frequency division multiplexing (DCO-OFDM) based adaptive transmission in the context of visible light communication (VLC). We ...
The impact of pulse shaping filters on OFDM-based visible light communications
This paper discusses the impact of pulse shaping filter on the performance of orthogonal frequency division multiplexing (OFDM) based visible light communication (VLC) systems. Particularly, direct current biased optical ...
Tracking capacitance of liquid crystal devices to improve polarization rotation accuracy
(Optical Society of America, 2017-08-21)
We report a capacitance tracking method for achieving arbitrary polarization rotation from nematic liquid crystals. By locking to the unique capacitance associated with the molecular orientation, any polarization rotation ...
Uncertainty in risk of highway bridges assessed for integrated seismic and flood hazards
(Taylor and Francis, 2017-11-24)
Probabilistic risk assessment for bridges under natural hazards is of great interest to engineers for the development of risk mitigation strategies and implementation plans. The present study evaluates risk of an existing ...
LHC constraints on color octet scalars
(American Physical Society, 2017-08-09)
We extract constraints on the parameter space of the Manohar and Wise model by comparing the cross sections for dijet, top-pair, dijet-pair,t (t) over bart (t) over bar and b (b) over barb (b) over bar productions at the ...
Rf energy harvesting and transfer for spectrum sharing cellular iot communications in 5g systems
This paper proposes an energy and spectrum efficient IoT network for 5G systems where spectrum is shared with the cellular system for spectrum efficiency and energy harvesting and energy transfer are utilized for energy ...
