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 ...
Space, time, and iconicity in Turkish sign language (tid)
(Estonian Academy Publishers, 2012)
Much evidence points to the conclusion that temporal concepts are drawn primarily from the conceptualization of space. Sign languages provide a particularly suitable area for observing such a relationship since they employ ...
Student conference as a student centred environment for integrating technical writings into computer engineering curriculum
(Anı Yayıncılık, 2011-12)
Problem Statement: In today's world there are pressures on universities to ensure that graduates have the capacity to meet the needs of employers. One aspect of this is to ensure that students, along with professional ...
An analysis of stability of uncertain neural networks with multiple time delays
(Pergamon-Elsevier Science Ltd, 2013-09)
This paper deals with the problem of robust stability of neural networks with multiple time delays with the class of unbounded and nondecreasing activation functions. By constructing a suitable Lyapunov functional and ...
Relative response of TL and component-resolved OSL to alpha and beta radiations in annealed sedimentary quartz
(Pergamon-Elsevier Science Ltd, 2011-10)
Knowledge of the relative luminescence response to alpha and beta radiation is very important in TL and OSL dating. In the present study the relative alpha to beta response is studied in a sedimentary quartz sample, ...
Stability of solitary waves for three-coupled long wave-short wave interaction equations
(Oxford Univ Press, 2011-08)
In this paper, we consider a three-component system of 1D long wave-short wave interaction equations. The system has two-parameter family of solitary wave solutions. We prove orbital stability of the solitary wave solutions ...
A low complexity modulation classification algorithm for MIMO systems
(IEEE-INST Electrical Electronics Engineers Inc, 2013-10)
A novel algorithm is proposed for automatic modulation classification in multiple-input multiple-output spatial multiplexing systems, which employs fourth-order cumulants of the estimated transmit signal streams as ...
Blow-up and global existence for a general class of nonlocal nonlinear coupled wave equations
(Academic Press Inc Elsevier Science, 2011-02-01)
We study the initial-value problem for a general class of nonlinear nonlocal coupled wave equations. The problem involves convolution operators with kernel functions whose Fourier transforms are nonnegative. Some well-known ...
Thermoluminescence as a probe in bioactivity studies; the case of 58S sol-gel bioactive glass
(IOP Publishing Ltd, 2011-10-05)
The formation of a carbonated hydroxyapatite (HCAp) layer on the surface of bioactive materials is the main reaction that takes place upon their immersion in physiological fluids. To date, all techniques used for the ...
Cyclostationarity-based robust algorithms for QAM signal identification
(IEEE-INST Electrical Electronics Engineers Inc, 2012-01)
This letter proposes two novel algorithms for the identification of quadrature amplitude modulation (QAM) signals. The cyclostationarity-based features used by these algorithms are robust with respect to timing, phase, and ...
