A general assessment index for non-probabilistic reliability of structures with bounded field and parametric uncertainties

, 2020
This paper focuses on the reliability assessment of structures exhibiting both bounded field uncertainties and uncertain-but-bounded parameters in a non-probabilistic framework. Based on the bounded field model for spatially varying uncertainties and the

Bounds on Harary index

Journal of Mathematical Chemistry, 2009
In this paper, we obtain the lower and upper bounds on the Harary index of a connected graph (molecular graph), and, in particular, of a triangle- and quadrangle-free graphs in terms of the number of vertices, the number of edges and the diameter.

Sidelining the Mean: The Relative Variability Index as a Generic Mean-Corrected Variability Measure for Bounded Variables

Psychological methods, 2018
Variability indices are a key measure of interest across diverse fields, in and outside psychology. A crucial problem for any research relying on variability measures however is that variability is severely confounded with the mean, especially when ...

Bounds for the Randić Connectivity Index

Journal of Chemical Information and Computer Sciences, 1999
For a saturated hydrocarbon with n carbon atoms and m carbon-carbon bonds and with Randic connectivity index chi, two functions, L = L(n,m) and U = U(n,m), are determined, such that L < or = chi < U. These bounds are better than those previously reported; for most chemically relevant values of n and m there exist hydrocarbons for which chi = L or chi =

GEOMETRIC BOUNDS ON THE RELATIVE INDEX

Journal of the Institute of Mathematics of Jussieu, 2002
The author introduces the notion of the relative index for a pair of embeddable CR structures. Let \((Y,{\xi})\) be a contact 3-manifold with the contact structure \(\xi\). Let \(J,J^{\prime}\) denote a pair of embeddable CR structures on \(Y\), compatible with \(\xi\).

Special Jordan nil algebras of bounded index

Algebra and Logic, 1983
The Nagata-Higman theorem states that an associative nil-algebra of bounded index n, without elements of additive order \(\leq n\), is nilpotent. An example due to \textit{G. V. Dorofeev} [Usp. Mat. Nauk 15, No.3(93), 147-150 (1960; Zbl 0095.023)] shows this theorem cannot be fully extended to Jordan algebras.

Atom-Bond Connectivity Index and Arithmetic-Geometric Index: Bounding Relationships

International Journal of Mathematics and Computer Science
In this paper, we establish extremal results and bounds of the atom-bond connectivity index with the arithmetic-geometric index given the minimum and maximum degrees of a graph. We have shown that regular graphs correspond to extremal graphs.
