Interactions between Digital Geometry and Combinatorics on Words [PDF]
We review some recent results in digital geometry obtained by using a combinatorics on words approach to discrete geometry. Motivated on the one hand by the well-known theory of Sturmian words which model conveniently discrete lines in the plane, and on ...

Decidability of multiset, set and numerically decipherable directed figure codes [PDF]
Codes with various kinds of decipherability, weaker than the usual unique decipherability, have been studied since multiset decipherability was introduced in mid-1980s.

Maximal 0-1-fillings of moon polyominoes with restricted chain lengths and rc-graphs [PDF]
We show that maximal 0-1-fillings of moon polynomials, with restricted chain lengths, can be identified with certain rc-graphs, also known as pipe dreams.

The site-perimeter of words [PDF]
We define $[k]={1, 2, 3,ldots,k}$ to be a (totally ordered) {em alphabet} on $k$ letters. A {em word} $w$ of length $n$ on the alphabet $[k]$ is an element of $[k]^n$.

Cloud Versus Void Chord Length Distributions (LvL) as a Measure for Cloud Field Organization
Abstract Cloud organization impacts the radiative effects and precipitation patterns of the cloud field. Deviating from randomness, clouds exhibit either clustering or a regular grid structure, characterized by the spacing between clouds and the cloud size distribution. The two measures are coupled but do not fully define each other.

Polyominoes with nearly convex columns: A model with semidirected blocks [PDF]
In most of today's exactly solved classes of polyominoes, either all members are convex (in some way), or all members are directed, or both. If the class is neither convex nor directed, the exact solution uses to be elusive.

Minimum area polyomino Venn diagrams
Polyomino Venn (or polyVenn) diagrams are Venn diagrams whose curves are the perimeters of orthogonal polyominoes drawn on the integer lattice. Minimum area polyVenn diagrams are those in which each of the 2n intersection regions, in a diagram of n ...

Combinatorics of Labelled Parallelogram polyominoes [PDF]
We obtain explicit formulas for the enumeration of labelled parallelogram polyominoes. These are the polyominoes that are bounded, above and below, by north-east lattice paths going from the origin to a point (k,n).
