A note on the spherical images of W-partially null curves in Minkowski space-time E-1(4)
(Tbilisi Centre Math Sci, 2019)
In this study, we investigate the tangent, principal normal and trinormal spherical images of a W-partially null curve in pseudohyperbolic space H-0(3) of Minkowski space time E-1(4). The tangent, principal normal spherical ...
A NEW CONSTRUCTION OF TIMELIKE RULED SURFACES WITH CONSTANT DISTELI-AXIS
(Honam Mathematical Soc, 2020)
In this study, we construct timelike ruled surfaces whose Disteli-axis is constant in Minkowski 3-space E-1(3). Then we attain a general system characterizing these surfaces, and also give necessary and sufficient conditions ...
On k-type pseudo null slant helices due to the Bishop frame in Minkowski 3-space E-1(3)
(Amer Inst Mathematical Sciences-Aims, 2020)
In this study, we examine k-type pseudo null slant helices due to the Bishop frame, where k is an element of{0, 1, 2}. There are two different cases of the Bishop frame of a pseudo null curve related to the Bishop curvatures. ...
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 ...
On the best approximate (P,Q)-orthogonal symmetric and skew-symmetric solution of the matrix equation AXB=C
(Walter De Gruyter Gmbh, 2014)
Suppose that the matrix equation AXB-C with unknown matrix X is given, where A, B, and C are known matrices of suitable size. The matrix nearness problem is considered over the (P, Q)-orthogonal symmetric and (P, Q)-orthogonal ...
A new version of bienergies and biangles for curves framed by extended darboux frame
(Springer, 2021)
In this work, we research geometrical interpretation involved with the bienergy by ED-frame fields of the first and second types on an orientable hypersurface in E-4. We explore the geometric features of some charts by ...
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 ...
Significant role of the specific prime number p = 257 in the improvement of cryptosystems
(Bulgarian Acad Science, 2020)
Cryptology is the significant science which is inseparable from the means of communication of secrets. In a safe manner, it has the main objective of transmitting (potentially sensitive) information between two interlocutors. ...
A TYCHONOFF THEOREM FOR GRADED DITOPOLOGICAL TEXTURE SPACES
(Ankara Univ, Fac Sci, 2020)
In this paper, initial and product graded ditopologies are formulated and accordingly it is shown that dfGDitop is a topological structure over dffex x dffex. By means of spectrum idea, (di)compactness in graded ditological ...
On The Darboux Frame Motion of a Developable Surface
(Centre Environment Social & Economic Research Publ-Ceser, 2021)
Developable ruled surfaces and the rotation-minimizing frames (RMF) have a crucial importance in computer-aided geometric design (CAGD) because of being unfoldable (developable) into a plane without distortion. Also, the ...
