Tilings, tiling spaces and topology [PDF]

open access: yesPhilosophical Magazine, 2006
To understand an aperiodic tiling (or a quasicrystal modeled on an aperiodic tiling), we construct a space of similar tilings, on which the group of translations acts naturally. This space is then an (abstract) dynamical system. Dynamical properties of the space (such as mixing, or the spectrum of the translation operator) are closely related to bulk ...

An Efficient Tile-Pyramids Building Method for Fast Visualization of Massive Geospatial Raster Datasets

open access: yesAdvances in Electrical and Computer Engineering, 2016
Building tile-pyramids is an effective way for publishing and accessing the map visualization service of large-scale geospatial data in the web. But it is a time-consuming task in Geographic Information System (GIS) to build tile-pyramids using ...

Counting With Irrational Tiles [PDF]

open access: yes, 2014
We introduce and study the number of tilings of unit height rectangles with irrational tiles. We prove that the class of sequences of these numbers coincides with the class of diagonals of N-rational generating functions and a class of certain binomial ...

Spotlight Tiling

open access: yesAnnals of Combinatorics, 2010
This article introduces spotlight tiling, a type of covering which is similar to tiling. The distinguishing aspects of spotlight tiling are that the "tiles" have elastic size, and that the order of placement is significant. Spotlight tilings are decompositions, or coverings, and can be considered dynamic as compared to typical static tiling methods.

The pair annihilation reaction D + D --> 0 in disordered media and conformal invariance

open access: yes, 2007
The raise and peel model describes the stochastic model of a fluctuating interface separating a substrate covered with clusters of matter of different sizes, and a rarefied gas of tiles.

Self-Affine Tilings with Several Tiles, I

open access: yesApplied and Computational Harmonic Analysis, 1999
A collection \(T_i \subseteq {\mathbb R}^d\), \(i=1, \ldots, M\), together with an expanding \(d\times d\) matrix \(A\), and a collection of sets \(\Gamma_{ij} \subseteq {\mathbb Z}^d\), \(i,j=1, \ldots, M\), is called \textit{self-affine} if \[ AT_i = \bigcup_{j=1}^M (\Gamma_{ij}+T_j), \;\;(i=1, \ldots, M) \] (the sets in the union above are assumed ...

Performance Testing on Vector vs. Raster Map Tiles—Comparative Study on Load Metrics

open access: yesISPRS International Journal of Geo-Information, 2020
Recent developments in web map applications have widely affected how background maps are rendered. Raster tiles are currently considered as a regular solution, while the use of vector tiles is becoming more widespread.

Wireless Multicast for Zoomable Video Streaming

open access: yes, 2015
Zoomable video streaming refers to a new class of interactive video applications, where users can zoom into a video stream to view a selected region of interest in higher resolutions and pan around to move the region of interest. The zoom and pan effects

Odraz dobovej meštianskej módy na košických nálezoch kachlíc z 15. – 16. storočia

open access: yesArchaeologia Historica, 2016
Príspevok spracováva neveľký súbor kachlíc a foriem na kachlice z Košíc cez optiku dobovej módy, ktorá je na nich zobrazená. Žánrovej pestrosti motívov súboru kachľových výrobkov je nadradený hlavný predmet záujmu a tým sú odevy zobrazených postáv.
