A conceptually simple first wall (FW) and blanket design for an inertial fusion system based on utilizing mobile FW tiles is presented. Using these tiles that are periodically removed, annealed, and reinstalled, tritium retention and surface erosion concerns for inertial fusion FW could be mitigated. A conceptual configuration has been developed with consideration for laser beam port accommodat...

Although quad-trees are not the most successful strategy in image coding, some generalized subdivision schemes have been proposed recently. This work exploits a moderate generalization of quad-trees where tiles are not restricted to be split in both dimensions, which leads to a previously developed graph of anisotropic tiles called “bush”. An algorithm is developed to find the minimal number of...

An aperiodic tiling is one which uses a nite set of prototiles to tile space such that there is no translational symmetry within any one tiling. These tilings are of interest to researchers in the natural sciences because they can be used to model and understand quasicrystals, a recently-discovered type of matter which bridges the gap between glass, which has no regular structure, and crystals,...

A Wang tile [12] is a unit square with each edge colored from a finite set of colors Σ. A set S of Wang tiles is said to tile a planar grid Z if copies of tiles from S can be placed, one at each grid position, such that abutting edges of adjacent tiles have the same color. Multiple copies of any tile may be used, with no restriction on the number. If we allow the tiles to be rotated or reflecte...

SKI is a Turing complete, language for programming in the aTAM model. A compilation technique provides a mapping from SKI into finite sets of DNA Tiles that self-assemble in the aTAM model. Though such sets are always finite, the number of Tiles may be relevant, the construction of the Tiles may be heavy and the self-assembly can produce wrong molecular growth. In this paper we discuss the cons...

Ceramic tiles have become very popular and are used in the flooring of offices and shopping malls. As testing the quality of tiles manually in a highly polluted environment in the manufacturing industry is a laborintensive and time consuming process, analysis is carried out on the tile images. This paper discusses an automated system to detect the defects on the surface of ceramic tiles based o...

Abstract This statement presents a novel expressive medium that the authors call Ambiguus tiles, which construct dual-view tile mosaics. While similar to wall and surface mosaics made with conventional tiles can be assembled rearranged create in any size form. Fact vs. Fiction, letter sculpture composed of 115 is presented here as an example creative possibilities for using ready-to-use design ...

We used classification images to examine whether certain parts of a surface are particularly important when judging its colour, such as its centre, its edges, or where one is looking. The scene consisted of a regular pattern of square tiles with random colours from along a short line in colour space. Targets defined by a square array of brighter tiles were presented for 200ms. The colours of th...

This paper provides a bridge between the classical tiling theory and cellular automata on one side, and the complex neighborhood self-assembling situations that exist in practice, on the other side. A neighborhood N is a finite set of pairs (i, j) ∈ Z, indicating that the neighbors of a position (x, y) are the positions (x + i, y + j) for (i, j) ∈ N . This includes classical neighborhoods of si...

Some tiles derived from regular polygons can produce spiral tilings of the plane [1]. This paper considers some more general classes of tilings with tiles derived from regular polygons, some have central symmetry, many have periodic symmetry, some have both, and a few have no symmetry at all. Any of these tiling patterns could be the basis for some interesting mathematical art, for example by c...
