A new ranking method for trapezial fuzzy numbers and its application to fuzzy risk analysis
(Ios Press, 2015)In this study, a new method for ranking trapezial fuzzy numbers, generalized trapezoidal fuzzy numbers with different left and right heights, is presented. It considers triangles of a trapezium, a quadrilateral with no ... -
On differential inclusions with prescribed attainable sets
(Academic Press Inc Elsevier Science, 2003)In this article, the inverse problem of the differential inclusion theory is studied. For a given epsilon > 0 and a continuous set valued map t --> W(t), t is an element of [t(0), theta], where W(t) subset of R-n is compact ... -
A Fictitious Play Algorithm for Matrix Games with Fuzzy Payoffs
(Hindawi LTD, 2012)Fuzzy matrix games, specifically two-person zero-sum games with fuzzy payoffs, are considered. In view of the parametric fuzzy max order relation, a fictitious play algorithm for finding the value of the game is presented. ... -
Matrix rings with summand intersection property
(Czechoslovak Mathematical Journal, 2003)A ring R has right SIP (SSP) if the intersection (sum) of two direct summands of R is also a direct summand. We show that the right SIP (SSP) is the Morita invariant property. We also prove that the trivial extension of R ... -
On modules and matrix rings with sip-extending
(Mathematical Soc Rep China, 2007)In this note we study modules with the property that the intersection of two direct summands is essential in a direct summand (SIP-extending). Amongst other results we show that the class of right SIP-extending modules is ... -
Scattering of sound waves by an infinite grating composed of rigid plates
(Elsevier Science BV, 2007)A plane sound wave is incident at an angle theta upon an infinite array of rigid plates, equally spaced and lying along the y-axis, where (x, y) are two-dimensional Cartesian coordinates. The boundary value problem is ... -
The approximation of reachable sets of control systems with integral constraint on controls
(Springer International Publishing Ag, 2007)In this paper an approximation method for the construction of reachable sets of control systems with integral constraints on the control is considered. It is assumed that the control system is non-linear with respect to ... -
A note on positive Lyapunov exponent and sensitive dependence on initial conditions
(Pergamon-Elsevier Science LTD, 2001)In this note, we give two examples of discrete dynamics (Functions) on intervals C R, the first having a positive Lyapunov exponent at a point but not being sensitive-dependent on initial conditions at that point; and the ... -
Approximation of the attainable sets of the nonlinear control systems with integral constraint on controls
(Pergamon-Elsevier Science LTD, 2009)In this article the attainable sets of a control system are investigated. It is assumed that the behavior of the control system is described by a differential equation which is nonlinear with respect to the phase state ... -
Comparison of rotordynamic coefficients for labyrinth seals using a two-control volume method
(SAGE Publications LTD, 2008)In the current paper, the gas flow in straight through labyrinth seals is investigated using a two-control volume model. The continuity and the circumferential momentum equations are reobtained using the above model and ... -
Finite-monotonicity of eigenfunctions of the Laplacian on the Sierpinski Gasket
(World Scientific Publ Co Pte LTD, 2005)We show that the restriction of an eigenfunction of the Laplacian on the Sierpinski Gasket (SG) to any segment inside the SG is monotone on finite pieces, i.e. there is a subdivision of the segment, such that the function ... -
Derivatives of the restrictions of harmonic functions on the Sierpinski gasket to segments
(Academic Press Inc Elsevier Science, 2007)We give an explicit derivative computation for the restriction of a harmonic function on SG to segments at specific points of the segments: The derivative is zero at points dividing the segment in ratio 1:3. This shows ... -
The circle as an attractor of an iterated function system on the plane
(Academic Press Inc Elsevier Science, 2007)We give an iterated function system (IFS) on the plane with the circle as attractor. In doing this, we also give a sufficient condition for radially contracting functions on the plane (or on R-n) to be a contraction. A ... -
A note on a theorem of Rantzer
(John Wiley & Sons LTD, 2002)In this note we fill the missing cases of a theorem of Rantzer on the relationship between n-convex directions and the growth condition. We mainly show that if a second or a third order polynomial is a 3-convex direction, ... -
An estimate of the oscillation of harmonic reproducing kernels with applications
(Academic Press Inc Elsevier Science, 2016)We estimate the oscillation of harmonic reproducing kernels. As an application of this estimation we obtain a double integral characterization of harmonic Besov spaces -
On the approximation of the set of trajectories of control system described by a Volterra integral equation
(Inst Mathematics & Informatics, 2014)In this paper, the set of trajectories of the control system described by a nonlinear Volterra integral equation is studied. It is assumed that the set of admissible control functions is the closed ball of the space L-p, ... -
Spaces of skew-symmetric matrices satisfying A(3) = lambda A
(Elsevier Science Inc, 2013)We calculate the maximum dimension of a space of m x m real skew-symmetric matrices of corank 1 satisfying A(3) = lambda(A)A for some real lambda(A) > 0 -
Modifications of the Ricci tensor and applications
(Birkhauser Verlag Ag, 2010)By using two modified Ricci tensors, we prove some theorems which correspond to Myers's diameter estimate theorem and Bochner's vanishing theorem. -
The Bochner technique and modification of the Ricci tensor
(Springer, 2009)In the well-known vanishing theorems of Bochner, the assumptions Ric a parts per thousand yen 0 and Ric a parts per thousand currency sign 0 are modified by using Hessian and Laplacian of a smooth positive function such ... -
The Bakry-Emery Ricci tensor and its applications to some compactness theorems
(Springer, 2012)Let (M, g) be a complete and connected Riemannian manifold of dimension n. By using the Bakry-Emery Ricci curvature tensor on M, we prove two theorems which correspond to the Myers compactness theorem.
