A different view of the tube surface in Minkowski 3-space E-1(3)
(Tbilisi Centre Math Sci, 2021)
A basic goal of this paper is to study the tube surface with a null Cartan curve with respect to the Bishop frame in Minkowski 3-space E-1(3) and to compute some geometric features for this kind of the tube surface such ...
On a variational problem due to the B-Darboux frame in Euclidean 3-space
(Wiley, 2021)
In this paper, we introduce a new frame which is called the B-Darboux frame on a surface in Euclidean 3-space. We know that the parallel transport frame is derived from the Frenet frame along a space curve on a surface. ...
Zonal geomagnetic indices estimation of the two super geomagnetic activities of 2015 with the artificial neural networks
(Elsevier Sci Ltd, 2021)
This paper discusses the estimation of zonal geomagnetic indices of two super geomagnetic activities of 2015 in the 24th solar cycle. It estimates the zonal geomagnetic indices (Dst, ap, AE) of 17 March and 22 June 2015 ...
Representation of integers by k-generalized Fibonacci sequences and applications in cryptography
(World Scientific Publ Co Pte Ltd, 2021)
The aim of this paper is to construct a relation between tribonacci numbers and generalized tribonacci numbers. Besides, certain conditions are obtained to generalize the representation of a positive integer N which is ...
Analysis of the first four moderate geomagnetic storms of the year 2015
(Springer Heidelberg, 2021)
This essay investigates the first four moderate geomagnetic activities (the 04 January storm, the 07 January storm, the 17 February storm, and the 24 February storm) of 2015 in the 24th solar cycle. The essay attempts to ...
Practical stability analysis of perturbed fuzzy control system related to unperturbed fuzzy control system
(Scientific Technical Research Council Turkey-Tubitak, 2021)
The behavior of solutions of a perturbed fuzzy control system with respect to an original unperturbed fuzzy control system is investigated. Notions of practical stability, asymptotic stability and instability are introduced. ...
On the system of double equations with three unknowns d
(Semnan Univ, 2021)
The system of double equations with three unknowns given by d + ay + bx + cx(2) = z(2), y + z = x(2) is analysed for its infinitely many non-zero distinct integer solutions. Different sets of integer solutions have been ...
Sparse polynomial interpolation with Bernstein polynomials
(Scientific Technical Research Council Turkey-Tubitak, 2021)
We present an algorithm for interpolating an unknown univariate polynomial f that has a t sparse representation (t << deg(f) ) using Bernstein polynomials as term basis from 2t evaluations. Our method is based on manipulating ...
On computing the degree of a Chebyshev Polynomial from its value
(Academic Press Ltd- Elsevier Science Ltd, 2021)
Algorithms for interpolating a polynomial f from its evaluation points whose running time depends on the sparsity to f the polynomial when it is represented as a linear combination of t Chebyshev Polynomials of the First ...
A NEW CONSTRUCTION OF BIENERGY AND BIANGLE IN LORENTZ 5-SPACE
(Honam Mathematical Soc, 2021)
In this study, we firstly compute the energies and the angles of Frenet vector fields in Lorentz 5-space L-5. Then we obtain the bienergies and biangels of Frenet vector fields in L-5 by using the values of energies and ...
