Cognitive cooperative MAC with one primary and two secondary users: achievable rates and optimal power control
(IEEE-INST Electrical Electronics Engineers Inc, 2014-11)
We consider a three-user fading cognitive cooperative multiple access channel (MAC) with one primary and two secondary transmitters. We propose two encoding/decoding strategies with varying levels of cooperation, based on ...
Investigation of the OSL signal from very deep traps in natural quartz
(Univ Agean, Dept Mediterranean Stud, 2010)
It has been recently reported by several studies that a thermally transferred optically stimulated luminescence (TT-OSL) signal from quartz grains can be used to extend the dating range for quartz samples. The TT-OSL signals ...
Numerical simulation of blow-up solutions for the generalized Davey-Stewartson system
(Taylor & Francis Ltd, 2011-03)
Blow-up solutions for the generalized Davey-Stewartson system are studied numerically by using a split-step Fourier method. The numerical method has spectral-order accuracy in space and first-order accuracy in time. To ...
Multiple time scale formalism and its application to long water waves
(Elsevier Science Inc, 2010-05)
In the present work, by employing the multiple time scaling method, we studied the non-linear waves in shallow-water problem and obtained a set of Korteweg-deVries equations governing the various order terms in the ...
Nonreciprocal switching of VO2 thin films on microstructured surfaces
(Optical Soc Amer, 2010-05-15)
We demonstrate that the combination of near-field focusing and a switchable oxide layer permits construction of a modulator with different optical switching thresholds in two opposing directions. For that purpose VO2 layers ...
IRSL dating of a deep water core from Pylos, Greece; comparison to post ir blue OSL and TL dating results
(Univ Agean, 2011)
The 'double SAR' protocol procedure permits the determination of two equivalent dose (De) values for each polymineral aliquot; an IRSL De resulting mostly from feldspars along with a post-IR OSL De for a mixed signal for ...
Factored particle filtering with dependent and constrained partition dynamics for tracking deformable objects
(Springer, 2014-10)
In particle filtering, dimensionality of the state space can be reduced by tracking control (or feature) points as independent objects, which are traditionally named as partitions. Two critical decisions have to be made ...
A novel image compression method based on classified energy and pattern building blocks
(Springer International Publishing AG, 2011)
In this paper, a novel image compression method based on generation of the so-called classified energy and pattern blocks (CEPB) is introduced and evaluation results are presented. The CEPB is constructed using the training ...
Turkey’s military victory over the PKK and its failure to end the PKK insurgency
(Routledge journals, Taylor & Francis Ltd, 2015-09-03)
This article explores the major reasons why Turkey could not end the PKK insurgency despite its military defeat in the late 1990s. It argues that Turkish governments have failed to sufficiently address two key aspects of ...
Algebraic break of image ciphers based on discretized chaotic map lattices
(Elsevier Science Inc, 2011-01-01)
In this paper, we provide an algebraic cryptanalysis of a recently proposed chaotic image cipher. We show that the secret parameters of the algorithm can be revealed using chosen-plaintext attacks. Our attack uses the orbit ...
