Coupled plasmon-LO-phonon modes in GaInAs quantum wires
(American Institute of Physics., 1996-06-20)We study the collective excitation modes of coupled quasi-one-dimensional electron gas and longitudinal-optical phonons in GaInAs quantum wires within the random-phase approximation. In contrast to the higher-dimensional ... -
An online adaptive cooperation scheme for spectrum sensing based on a second-order statistical method
(Institute of Electrical and Electronics Engineers, 2012)Spectrum sensing is one of the most important features of cognitive radio (CR) systems. Although spectrum sensing can be performed by a single CR, it is shown in the literature that cooperative techniques, including multiple ... -
Optimization of transportation requirements in the deployment of military units
(Bilkent University, 2005)We study the deployment planning problem (DPP) that may roughly be defined as the problem of the planning of the physical movement of military units, stationed at geographically dispersed locations, from their home ... -
Optimization of transportation requirements in the deployment of military units
(Elsevier, 2007)We study the deployment planning problem (DPP) that may roughly be defined as the problem of the planning of the physical movement of military units, stationed at geographically dispersed locations, from their home bases ... -
Physical layer security over frequency selective fading channels
(Bilkent University, 2016-01)The inherent open nature of the transmission medium makes security a challenging issue in wireless networks. Physical layer security, which is an alternative or a complement to the cryptographic approaches, exploits the ... -
Production of ‘abstract crisis’ and irregular human mobilities
(Bilkent University, 2019-08)This thesis argues that political representation of space as being consisted of territorially bounded states leads to the impulsion to see an uncontrolled movement as risky, and eventually to call the event as crisis. ... -
Step-edge-induced resistance anisotropy in quasi-free-standing bilayer chemical vapor deposition graphene on SiC
(AIP Publishing, 2014)The transport properties of quasi-free-standing (QFS) bilayer graphene on SiC depend on a range of scattering mechanisms. Most of them are isotropic in nature. However, the SiC substrate morphology marked by a distinctive ... -
User grouping in wireless networks with full duplex base stations and legacy mobile stations
(Bilkent University, 2018-08)Improving spectral efficiency is a key objective in next generation wireless networks. Recent advances in self-interference cancellation techniques made in-band full-duplex wireless communications possible. Unlike ...
