MATHEMATICAL MODELING OF COVID-19 PHENOMENON; THE CASES: GERMANY, ISRAEL AND CANADA
(Parlar Scientific Publications (P S P), 2020)
Epidemic diseases are described as a pandemic that affects the enormous majority of the world, spreads rapidly among people, and causes deaths. Negative effects, the number of casualties, rates of spread, and the duration ...
ON THE CONSTRUCTION OF PSEUDO-FINSLER EIKONAL EQUATIONS
(Honam Mathematical Soc, 2020)
In this study, we have generalized pseudo-Finsler map by introducing the concept of semi-Riemannian map and have found pseudo-Finsler eikonal equations using pseudo-Finsler map. After that, we have obtained some sufficient ...
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 ...
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 ...
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 ...
NORMAL DEVELOPABLE SURFACES OF A SURFACE ALONG A DIRECTION CURVE
(Indonesian Mathematical Soc, 2020)
We construct a developable surface normal to a surface along a curve on the surface. We choose the curve as the normal direction curve on which the new surface is formed in Euclidean space. We obtain some results about the ...
SIR MATHEMATICAL MODEL AND ESTIMATING OF COVID-19 EPIDEMIC SPREADING
(Parlar Scientific Publications (P S P), 2020)
The SIR (susceptible-infected-recovered) Epidemic Model has been utilized effectively in the struggle against past pandemics and has been useful. One can find a discussion here on six Mediterranean countries to support ...
