Complex tilings [PDF]

open access: yesJournal of Symbolic Logic, 2001
AbstractWe study the minimal complexity of tilings of a plane with a given tile set. We note that every tile set admits either no tiling or some tiling withKolmogorov complexity of its (n×n)-squares. We construct tile sets for which this bound is tight: all (n×n)-squares in all tilings have complexity Ω(n).

Finding minimum spanning trees more efficiently for tile-based phase unwrapping. [PDF]

open access: yes, 2006
The tile-based phase unwrapping method employs an algorithm for finding the minimum spanning tree (MST) in each tile. We first examine the properties of a tile's representation from a graph theory viewpoint, observing that it is possible to make use of a

CPAM: Cross Patch Attention Module for Complex Texture Tile Block Defect Detection

open access: yesApplied Sciences, 2022
Due to the little variation in defect points, tile block defect detection typically detects subtle defects in large-format images, allowing defective characteristics to be displayed regionally.

Regular tessellation of the Lobachevskii plane

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2019
This paper discusses a new algorithm for construction of regular tessellation of the Lobachevskii plane. The problems of combinatorial and topological arrangement of regular tessellations, finding the number of tiles in each layer of such tessellation ...

Shield tilings

open access: yesCoRR, 2023
We provide a complete description of the edge-to-edge tilings with a regular triangle and a shield-shaped hexagon with no right angle. The case of a hexagon with a right angle is also briefly discussed.

Le Massif central, approche iconographique et archéologique. Une mise au point à propos des couvertures médiévales

open access: yesArchéologie Médiévale
In the absence of significant excavations, the roofing materials remain poorly known in the Massif Central. Textual sources, such as iconographic images, partly answer the questions, as do the many surveys, and chance discoveries.

Observational Congruences for Dynamically Reconfigurable Tile Systems

open access: yes, 2005
The SOS formats that ensure that bisimilarity is a congruence fail in the presence of structural axioms on states. Dynamic bisimulation, introduced to characterize the coarsest congruence for CCS which is also a weak bisimulation, reconciles the ...
