Optimal relay placement in cooperative free-space optical communication systems
(IEEE, 2012)
Relay-assisted free-space optical (FSO) transmission exploits the fact that atmospheric turbulence fading variance is distance dependent and yields significant performance gains by taking advantage of the resulting shorter ...
Silver patterning using an atomic force microscope tip and laser-induced chemical deposition from liquids
(AIP Publishing, 2012)
This article presents a new direct patterning technique in which laser photoreduction of silver from a liquid is controlled by a scanning atomic force microscope tip. Contrary to expectations, the tip suppresses, rather ...
Alto sunuculu, eş görevli ağlarda dosya paylaşımı
(IEEE, 2012)
In current Internet, the most significant and the growing promotion rate of the network resources usage is due to the Peer to Peer(P2P) applications. These studies show us that the main traffic type, that Internet Service ...
Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC
(Elsevier, 2012-09-17)
Results are presented from searches for the standard model Higgs boson in proton-proton collisions at root s = 7 and 8 TeV in the Compact Muon Solenoid experiment at the LHC, using data samples corresponding to integrated ...
Adaptive power loading for multi-relay OFDM regenerative networks with relay selection
(IEEE, 2012-03)
In this paper, we propose an adaptive power loading algorithm for an OFDM (orthogonal frequency division multiplexing)-based multi-relay regenerative network with relay selection. The proposed scheme is based on selecting ...
Adaptive bit loading for multi-relay cooperative orthogonal frequency division multiple with imperfect channel estimation
(IEEE, 2012-08-14)
In this study, the authors introduce an adaptive bit loading scheme for an amplify-and-forward orthogonal frequency division multiple cooperative system with relay selection. The proposed bit loading scheme maximises the ...
QCD coupling constants and VDM
(AIP, 2012)
QCD sum rules for coupling constants of vector mesons with baryons are constructed.The corresponding QCD sum rules for electric charges and magnetic moments are also derived and with the use of vector-meson-dominance model ...
Predicting heat transfer from unsteady synthetic jets
(ASME, 2012-05-31)
Synthetic jets are piezo-driven, small-scale, pulsating devices capable of producing highly turbulent jets formed by periodic entrainment and expulsion of the fluid in which they are embedded. The compactness of these ...
A survey of software testing in the cloud
(IEEE, 2012)
Cloud computing has emerged as a new computing paradigm that impacts several different research fields, including software testing. Testing cloud applications has its own peculiarities that demand for novel testing methods ...
Theoretical determination of K(1)(1270,1400) mixing angle in QCD
(IOP Publishing, 2012)
In quark model, the strange axial vector mesons K1(1270) and K1(1400) are defined as the mixtures of orbital angular momentum states K1A and K1B. In this work, by using the orthogonality of the mass eigenstates, we have ...
