Diagonal Stability of Uncertain Interval Systems
(IEEE, 2015)In this paper we consider the problem of diagonal stability of interval systems. We investigate the existence and evaluation of a common diagonal solution to the Lyapunov and Stein matrix inequalities for third order ... -
Discrete Time Stability Margins From Stein's Equation
(IEEE, 2015)This paper deals with the robust stability of a discrete time stable state space system subject to structured real parameter uncertainty. Using Lyapunov's Theorem and Stein's equation the radius of a stability hypersphere ... -
Numerical Solutions of the Mrlw Equation Using Moving Least Square Collocation Method
(Ankara University, Fac Sci, 2017)In this paper, the Modified Regularized Long Wave (MRLW) equation is solved by using moving least square collocation (MLSC) method. To show the accuracy of the used method several numerical test examples are given. The ... -
Three different methods for numerical solution of the EW equation
(Elsevier Sci LTD, 2008)Numerical solutions of the equal width wave (EW) equation are obtained by using a Galerkin method with quartic B-spline finite elements, a differential quadrature method with cosine expansion basis and a meshless method ... -
Chaotic n-dimensional euclidean and hyperbolic open billiards and chaotic spinning planar billiards
(Siam Publications, 2008)We propose a new method to handle the n-dimensional billiard problem in the exterior of a finite mutually disjoint union of convex ( but not necessarily strictly convex) smooth obstacles without eclipse in the Euclidean ... -
Numerical solution of RLW equation using radial basis functions
(Taylor & Francis LTD, 2010)The numerical solution of the regularized long wave equation is investigated by means of the meshless method based on collocation with the well-known radial basis functions (RBFs). Single solitary wave motion, two solitary ... -
Numerical solutions of KdV equation using radial basis functions
(Elsevier Science Inc, 2008)Numerical solution of the Korteweg-de Vries equation is obtained by using the meshless method based on the collocation with radial basis functions. Five standard radial basis functions are used in the method of the ... -
Numerical solutions of the Kawahara type equations using radial basis functions
(Wiley-Blackwell, 2012)This study is carried out to investigate the numerical solutions of the Kawahara, KdV-Kawahara, and the modified Kawahara equations by using the meshless method based on collocation with radial basis functions. Results of ... -
Graph-directed fractal interpolation functions
(Scientific Technical Research Council Turkey-Tubitak, 2017)It is known that there exists a function interpolating a given data set such that the graph of the function is the attractor of an iterated function system, which is called a fractal interpolation function. We generalize ... -
A notion of robustness and stability of manifolds
(Academic Press Inc Elsevier Science, 2008)Starting from the notion of thickness of Parks we define a notion of robustness for arbitrary subsets of R-k and we investigate its relationship with the notion of positive reach of Federer. We prove that if a set M is ... -
Soliton solutions for NLS equation using radial basis functions
(Pergamon-Elsevier Science LTD, 2009)We present a numerical study of the cubic nonlinear Schrodinger equation by using the meshless method based on collocation with radial basis functions. The method is examined for the single soliton solution and interaction ... -
On the Minkowski measurability of self-similar fractals in R-d
(Scientific Technical Research Council Turkey-Tubitak, 2013)The question of Minkowski measurability of fractals is investigated for different situations by various authors, notably by M. Lapidus. In dimension one it is known that the attractor of an IFS consisting of similitudes ... -
Tube volumes via functional equations
(Springer Basel Ag, 2015)Tube formulas for convex sets and for smooth submanifolds of Euclidean spaces have long been of interest for geometers. In the last two decades there has been great progress on tube formulas for badly behaved spaces such ... -
On the smallest disks enclosing graph-directed fractals
(Pergamon-Elsevier Science LTD, 2018)We consider the graph-directed iterated function systems and give upper bounds for the diameters of the smallest disks enclosing their attractors. We also give an algorithm to obtain these smallest enclosing disks with any ... -
Tube Formulas for Graph-Directed Fractals
(World Scientific Publ Co Pte LTD, 2010)Lapidus and Pearse proved recently an interesting formula about the volume of tubular neighborhoods of fractal sprays, including the self-similar fractals. We consider the graph-directed fractals in the sense of graph ... -
Seiberg-Witten-Like Equations Without Self-Duality on Odd Dimensional Manifolds
(Global Science Press, 2018)In this paper, Seiberg-Witten-like equations without self-duality are defined on any smooth 2n+1-dimensional Spinc manifolds. Then, a non-trivial solution is given on the strictly-Pseudoconvex CR-5 manifolds endowed with ... -
On the Existence of Fagnano Trajectories in Convex Polygonal Billiards
(Maik Nauka/Interperiodica/Springer, 2009)We prove that an n-gon F is pedal strong Fagnano trajectory in some convex polygonal billiard table A if and only if it is a convex Poncelet n-gon. -
Stability of Graphs
(Electronic Journal Of Combinatorics, 2009)Positively weighted graphs have a natural intrinsic metric. We consider finite, positively weighted graphs with a positive lower bound for their minimal weights and show that any two such graphs, which are close enough ... -
The construction of maximum independent set of matrices via Clifford algebras
(Scientific Technical Research Council Turkey-Tubitak, 2007)In [1], [2] and [6] the maximum number of some special type n x n matrices with elements in F whose nontrivial linear combinations with real coefficients are nonsingular is studied where F is the real field R, the complex ... -
An equivalence class decomposition of finite metric spaces via Gromov products
(Elsevier Science BV, 2017)Let (X, d) be a finite metric space with elements P-i, i = 1,..., n and with the distance functions d(ij) The Gromov Product of the "triangle" (P-i, P-j, P-k) with vertices P-t, P-j and P-k at the vertex Pi is defined by ...
