Rotations on a lightcone in minkowski 3-Space
(Advances in Applied Clifford Algebras, Springer, 2017)
In this paper the generalization of the rotations on any lightcone in Minkowski 3-space ℝ1,2𝑔 is given. The rotation motion on the lightcone is examined by means of a bilinear form and Lorentzian notions. We use the ...
Generating hyperbolical rotation matrix for a given hyperboloid
(Linear Algebra and Its Applications, 2016)
Hyperbolic rotation is hyperbolically the motion of a smooth object on general hyperboloids given by −a1x2+a2y2+a3z2=±λ, λ ∈R+. In this paper, we investigate the hyperbolical rotation matrices in order to get the motion ...
Soft computing based e-commerce website service quality index measurement
(Elsevier, 2023)
It is observed that there is a need for a quality measurement template system that is easy to understand, effective,
easily updated according to different requests, contains enough variables, and gives fast results, which ...
Similar and self-similar null Cartan curves in Minkowski-Lorentzian spaces
(Communications Faculty of Sciences University of Ankara Series A1 Mathematics and Statistics, 2022)
In this paper, differential invariants of null Cartan curves are studied in (n+2) dimensional Lorentzian similarity geometry. The fundamental theorem for a null Cartan curve in similarity geometry is investigated and the ...
Healthy bread quality index based on food label information
(Elsevier, 2023)
The label on the package shows important information such as the origin, type, price, and nutritional and energy
value of the product during the purchase of the product. A decision support system is aimed at obtaining ...
Determining the quality index of online shopping websites by using fuzzy logic
(6th International New York Conference on Evolving Trends in Interdisciplinary Research and Practices, 2022)
Online shopping is a platform of e-commerce allowing consumers to purchase goods or services directly from a seller over the Internet using a web browser or a mobile application. Due to Covid-19 pandemic, almost every ...
On focal curves of null Cartan curves
(Turkish Journal of Mathematics, 2017)
The focal curve, which is determined as the locus of centers of osculating pseudo-spheres of a null Cartan curve, is investigated in Minkowski (n+2)-space Mn+2. Moreover, a curve called acceleration focal curve of a null ...
Determining the customer satisfaction index for civil aviation organizations based on fuzzy logic and servqual method
(International Capital Conference on Multidisciplinary Scientific Research, 2022)
The aviation sector in Türkiye is one of the sectors with the highest growth rate. Competition in the aviation industry in recent years has greatly affected the activities of businesses. For businesses to survive in the ...
A fuzzy logic approach and path algorithm for time and energy management of smart cleaning robots
(2023)
Smart home technologies (SHM) or devices provide some degree of digitally connected,
automated, or enhanced services to building occupants in residential areas and have been
becoming increasingly popular in recent years. ...
Bäcklund’s theorem for n dimensional lorentzian submanifold in the minkowski space 𝔼21𝑛−1
(Results in Mathematics, 2016)
In this paper, Bäcklund’s Theorem is introduced on the Lorentzian n-submanifold of the Minkowski space 𝔼2𝑛−11 by using the method of moving frames. Also, we prove the Integrability Theorem for the Lorentzian n-submanifold ...
