Power Control-Based Multi-User Li-Fi Using A Compound Eye Transmitter
(IEEE, 2015)
In visible light communications (VLC) the transmitted signal is non-negative and real valued and these characteristics constrain the signal space and provide new challenges for waveform design in a multi-user system. In ...
Modeling of Visible Light Channels and Performance Analysis of ACO-OFDM
(IEEE, 2015)
Spectrum scarcity of traditional radio communication has led communication engineers to find new alternatives. Indoor visible light communication is one alternative to solve this problem since its spectrum is not regulated ...
Optical OFDM with index modulation for visible light communications
(Institute of Electrical and Electronics Engineers Inc., 2015)
In this paper we propose optical orthogonal frequency division multiplexing with index modulation (O-OFDM-IM) for visible light communications (VLC) systems employing light emitting diodes (LEDs) and photodetectors (PDs). ...
(Mis)communication across the Borders: Politics media and public opinion in Turkey
(International Institute of Informatics and Systemics IIIS, 2015)
During the 1990s advances in statistical and demographic analysis helped the development of an understanding of public opinion as the collective view of a defined population such as a particular demographic or ethnic group. ...
Precoded single-cell multi-user MISO visible light communications
(Institute of Electrical and Electronics Engineers Inc., 2015)
This study investigates the effects of transmitter and receiver parameters on the performance of a precoded singlecell (SC) multi-user (MU) multi-input-single-output (MISO) visible light communication (VLC) system. A ...
Microscopic nuclear level densities by the shell model Monte Carlo method
(Cern, 2015)
The configuration-interaction shell model approach provides an attractive framework for the calculation of nuclear level densities in the presence of correlations but the large dimensionality of the model space has hindered ...
Investigation of allosteric communication pathways in human beta 2-adrenergic receptor
(Wiley-Blackwell, 2015)
[Abstract Not Available]
A MULTIPLE-CRITERIA DECISION MAKING METHOD FOR EVALUATING SOLAR POWER PLANT LOCATION ALTERNATIVES
(EDITURA ASE, 2015)
Solar energy is the most readily available source of energy and one of the most important sources of the renewable energy because it is non-polluting and helps in lessening the greenhouse effect. Main problem of establishing ...
Novel Channel Models For Visible Light Communications
(Spie-Int Soc Optical Engineering, 2015)
In this paper we investigate channel modeling for visible light communications (VLC) using non-sequential ray tracing simulation tools. We create three dimensional realistic simulation environments to depict indoor scenarios ...
Recent Advances in the Application of the Shell Model Monte Carlo Approach to Nuclei
(IOP Publishing Ltd, 2015)
The shell model Monte Carlo (SMMC) method is a powerful technique for calculating the statistical and collective properties of nuclei in the presence of correlations in model spaces that are many orders of magnitude larger ...
