Non-line-of-sight ultraviolet communications over atmospheric turbulence channels
(IEEE, 2015)
Ultraviolet (UV) communication enables non-line-of sight (NLOS) outdoor wireless connectivity and is particularly desirable to relax or eliminate pointing and tracking requirements of infrared links. In the current literature, ...
Outage performance of multi-hop hybrid FSO/RF communication systems
(IEEE, 2015)
In this paper, five scenarios are considered for the realization of a multi-hop hybrid free-space optical/radio frequency (FSO/RF) communication system with decode-and-forward (DF) relaying, and analytical outage probability ...
LIG at MediaEval 2015 multimodal person discovery in broadcast TV task
(CEUR-WS, 2015)
In this working notes paper the contribution of the LIG team (partnership between Univ. Grenoble Alpes and Ozyegin University) to the Multimodal Person Discovery in Broadcast TV task in MediaEval 2015 is presented. The ...
Non-orthogonal multiple access (NOMA) for indoor visible light communications
(IEEE, 2015)
Providing multiple access support to visible light communication (VLC) systems requires new networking architecture. Non-orthogonal multiple access (NOMA) is a proposed multiple access technique for future cellular systems. ...
Facile synthesis of 2D Zn(II) coordination polymer and its crystal structure, selective removal of methylene blue and molecular simulations
(Elsevier, 2017)
A new coordination polymer {[Zn(μ3-ppda)(H2O)(μ-bpa)Zn(μ-ppda)(μ-bpa)]·4H2O}n (1) (ppda = 1,4-phenylenediacetate, bpa = 1,2-bis(4-pyridyl)ethane) has been synthesized by microwave-assisted reaction and characterized by ...
Natural convection immersion cooling with enhanced optical performance of light-emitting diode systems
(2015-10-15)
Electronics driven at high currents may experience local hot spots, which may cause thermal degradation or even catastrophic failures. This common problem occurs at light-emitting diode (LED) chips and it is not easily ...
An area efficient real time implementation of dual tree complex wavelet transform in field programmable gate arrays
(IEEE, 2015)
Biomedical signals (BSs), which give information about the normal condition and also the inherent irregularities of our body, are expected to have non-stationary character due to the time-varying behavior of physiological ...
A probabilistic seismic hazard assessment for the Turkish territory—part I: the area source model
(Springer International Publishing, 2016)
The seismic zoning map of Turkey that is used in connection with the national seismic design code (versions issued both in 1997 and 2007) is based on a probabilistic seismic hazard assessment study conducted more than 20 ...
Effect of the probe location on the absorption by an array of gold nano-particles on a dielectric surface
(Elsevier, 2017)
Effect of silicon atomic force microscope probe position and particle spacing on the local absorption of an array of gold nanoparticles placed over a dielectric borosilicate glass surface are evaluated. An improved, ...
Spectrum trading for non-identical channel allocation in cognitive radio networks
(IEEE, 2013)
In this paper, we investigate spectrum trading via auction approach for exclusive usage spectrum access model in cognitive radio networks. We consider a realistic valuation function which depends on channel capacity, delay ...
