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 SPHERICAL INDICATRIES OF CURVES IN GALILEAN 4-SPACE
(Indonesian Mathematical Soc, 2019)Euclidean and non-Euclidean geometries can be considered as spaces that are invariant under a given group of transformations [8]. The geometry established by this approach is called Cayley-Klein geometry. Galilean 4-space ... -
Twisted surfaces with vanishing curvature in Galilean 3-space
(World Scientific Publ Co Pte Ltd, 2018)In this work, we define twisted surfaces in Galilean 3-space. In order to construct these surfaces, a planar curve is subjected to two simultaneous rotations, possibly with different rotation speeds. The existence of ... -
