General type of a uniform and reversible representation of chemical structures [PDF]

Analytica Chimica Acta, 1997
In any type of modelling (be classical or by artificial neural networks) involving chemical structures and their corresponding properties, the first problem encountered is the representation of chemical structures. A good structure representation should have different code for each 3-D structure (uniqueness), it should have the same number of variables

Reflectance, illumination, and appearance in color constancy

Frontiers in Psychology, 2014
We studied color constancy using a pair of identical 3-D Color Mondrian displays. We viewed one 3-D Mondrian in nearly uniform illumination, and the other in directional, nonuniform illumination.

Higher dimensional discrete Cheeger inequalities

Journal of Computational Geometry, 2015
For graphs there exists a strong connection between spectral and combinatorial expansion properties. This is expressed, e.g., by the discrete Cheeger inequality, the lower bound of which states that $\lambda(G) \leq h(G)$, where $\lambda(G)$ is the ...

Ergativity and depth of analysis [PDF]

, 2019
In this paper, I argue that “depth of analysis” does not deserve the prestige that it is sometimes given in general linguistics. While language description should certainly be as detailed as possible, general linguistics must rely on worldwide comparison

Characterizing the Delaunay decompositions of compact hyperbolic surfaces [PDF]

, 2001
Given a Delaunay decomposition of a compact hyperbolic surface, one may record the topological data of the decomposition, together with the intersection angles between the `empty disks' circumscribing the regions of the decomposition.

Integrable Euler top and nonholonomic Chaplygin ball [PDF]

, 2011
We discuss the Poisson structures, Lax matrices, $r$-matrices, bi-hamiltonian structures, the variables of separation and other attributes of the modern theory of dynamical systems in application to the integrable Euler top and to the nonholonomic ...

Parallel implementation of an optimal two level additive Schwarz preconditioner for the 3-D finite element solution of elliptic partial differential equations [PDF]

, 2002
This paper presents a description of the extension and parallel implementation of a new two level additive Schwarz (AS) preconditioner for the solution of 3-D elliptic partial differential equations (PDEs). This preconditioner, introduced in Bank et al. (

New Representations of Matroids and Generalizations [PDF]

, 2011
We extend the notion of matroid representations by matrices over fields and consider new representations of matroids by matrices over finite semirings, more precisely over the boolean and the superboolean semirings.
