Turbulence impact on wind turbines: experimental investigations on a wind turbine model
(IOP Publishing, 2016)
Experimental investigations have been conducted by exposing an efficient wind turbine model to different turbulence levels in a wind tunnel. Nearly isotropic turbulence is generated by using two static squared grids: fine ...
An adaptive modulation scheme for coded free-space optical systems
(IEEE, 2014)
For very slowly-varying fading channels as in the case of atmospheric turbulence-induced fading, it is possible to reliably estimate the channel state information and send it back to the transmitter. The transmitter can ...
An experimental and computational study on efficiency of white LED packages with a thermocaloric approach
(IEEE, 2017)
Thermal management of light-emitting diode (LED) chips is crucial for light extraction and lifetime. It is well known that the light output of an LED decreases with the elevated temperatures. For higher light extraction, ...
Field programmable gate arrays implementation of dual tree complex wavelet transform
(IEEE, 2015)
Due to the inherent time-varying characteristics of physiological systems, most biomedical signals (BSs) are expected to have non-stationary character. Therefore, any appropriate analysis method for dealing with BSs should ...
Cooperative visible light communications with full-duplex relaying
(IEEE, 2017-06)
In this paper, we investigate cooperative visible light communication (VLC) system where an intermediate light source acts as a relay terminal. We assume that relay terminal operates in full-duplex mode. In contrast to ...
Search for narrow resonances in dijet final states at s√=8 TeV with the novel CMS technique of data scouting
(American Institute of Physics Inc., 2017)
Narrow resonances decaying into dijet final states are searched with the data obtained from proton-proton collisions at a center-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 18.8 f b−1. The data ...
Nanoscale optical communications modulator and acousto-optic transduction with vibrating graphene and resonance energy transfer
(IEEE, 2017)
Graphene resonators are future promising in terms of ultra-low weight, high Young's modulus, strength and wideband resonance frequencies. Besides that, nanoscale optical wireless channels including visible light spectrum ...
Unmanned-aerial-vehicle-assisted cooperative communications for visible light communications-based vehicular networks
(SPIE, 2019-08)
We propose and investigate cooperative visible light communications (VLC) enabled vehicular network architecture with an unmanned aerial vehicle (UAV) relay. In the proposed system, a UAV equipped with an onboard photodetector ...
Performance investigation of the modified costas carrier recovery loop for a QPSK modulated signal in the presence of co-channel interference
(IEEE, 2016)
One of the important challenges in communication systems is drift in the carrier frequency of received signal due to the clock skew and Doppler effect. Every communication receiver requires an automatic frequency control ...
Simulation and analysis of a TET-walker robot motion
(IEEE, 2014)
Tetrahedral walker robots are a group of reconfigurable robots which makes them adaptable for the full spectrum of activities in places that wheeled robots are inapplicable. In this paper, two different gaits for a ...
