Compressive split-step Fourier method
(Işık University Press, 2015-02-09)
In this paper an approach for decreasing the computational effort required for the split-step Fourier method (SSFM) is introduced. It is shown that using the sparsity property of the simulated signals, the compressive ...
Analytical and numerical aspects of the dissipative nonlinear Schrödinger equation
(Işık University Press, 2016-02-15)
In this paper various analytical and numerical aspects of the dissipative nonlinear Schrodinger equation (d-NLS equation) are discussed. Decaying solitary wave type solutions derived by Demiray is reviewed and a new ...
Extremum seeking control of uncertain systems
(Işık University Press, 2017)
Extremum seeking is used in control problems where the reference trajectory or reference set point of the system is not known but it is searched in real time in order to maximize or minimize a performance function representing ...
On a regularized solution of the Cauchy problem for matrix factorizations of the Helmholtz equation
(Işık University Press, 2023-10)
In this paper, we consider the problem of recovering solutions for matrix factorizations of the Helmholtz equation in a multidimensional bounded domain from their values on a part of the boundary of this domain, i.e., the ...
On progressive wave solution for non-planar KDV equation in a plasma with q-nonextensive electrons and two oppositely charged ions
(Işık University Press, 2020)
In this paper, the ion-acoustic wave is investigated in a plasma with q-nonextensive electrons and two oppositely charged ions with varying masses. These parameters are found to modify the linear dispersion relation and ...
Harmonic resonance phenomena on nonlinear SH waves
(Işık University Press, 2023-04)
The interaction of shear horizontal (SH) waves in a two layered elastic medium and its mth harmonic component is studied. The dispersion relation is analysed to obtain the wave number-phase velocity pairs where the third ...
A note on the cylindrical waves with transverse distortion in a plasma with vortex electron distribution
(Işık University Press, 2020-01-20)
In the present work, employing the conventional reductive perturbation method and the nonlinear field equations of a plasma consisting of a cold electron uid, hot electrons obeying a non-isothermal (trapped/vortex-like) ...
Modeling internet access at home by fractional calculus and a correlation analysis with human development index
(Işık University Press, 2024-04)
In this study, we modeled broadband internet access at home data and investigated the relationship between the human development index and internet access in countries. The broadband Internet access at home is modeled using ...
Applications of the generalized homogeneous q-shift operator in q-polynomials
(Işık University Press, 2024-04)
In this paper, we construct the generalized homogeneous q-shift operatör rΦs ( a1, · · · , ar b1, · · · , bs ; q, cDxy). Then, we apply this operator to derive some q-identities such as: the generating function and its ...
The Y- index and coindex of VC₅C₇[p, q] and HC₅C₇[p, q] nanotubes
(Işık University Press, 2024-04)
The Y-index and coindex are degree based molecular structure descriptors that have been shown to give a high degree of predictability compare to Zagreb indices and F-index and their coindices for some physicochemical ...
