A labyrinth can be generated by tiles in the form of a white square with a black diagonal. As with the quarter-circle tiles, each such tile has two orientations. [3] The connectivity of the resulting labyrinth can be analyzed mathematically using percolation theory as bond percolation at the critical point of a diagonally-oriented grid.
Placement testing is a practice that many colleges and universities use to assess college readiness and determine which classes a student should initially take. Since most two-year colleges have open, non-competitive admissions policies, many students are admitted without college-level academic qualifications.
When referring to bullnose, it is sometimes modified by adding the word quarter or half. In the illustration, one piece of quarter-bullnose tile is juxtaposed with a plain piece of tile, to create a finished look — note that the top trim strip shows a quarter-bullnose on two of its sides.
A triomino tile is in the shape of an equilateral triangle approximately 1 in (2.5 cm) on each side and approximately 1 ⁄ 4 in (6.4 mm) thick. Each point of the triangle has a number (most often from 0 to 5, as in the Pressman version), [2] and each triomino has a unique combination of numbers, subject to the following restrictions:
QDGC - Quarter Degree Grid Cells (or QDS - Quarter degree Squares) are a way of dividing the longitude latitude degree square cells into smaller squares, forming in effect a system of geocodes. Historically QDGC has been used in a lot of African atlases.
A set of yellow truncated domes on the down-ramp in a parking lot. Tactile paving (also called tenji blocks, truncated domes, detectable warnings, tactile tiles, tactile ground surface indicators, tactile walking surface indicators, or detectable warning surfaces) is a system of textured ground surface indicators found at roadsides (such as at curb cuts), by and on stairs, and on railway ...
A spot plate, also called a reaction plate, color test plate, [1] or spotting tile (British English), is a laboratory tool made either from ceramics or plastics. [2] Each plate consists of many cavity-like depressions in which only small amount of reactants can be added at a time. [ 3 ]
A close-up view of an Alberich tile, illustrating patterns of multiple holes with different diameters. The technology of anechoic tiles was developed by the Kriegsmarine during the Second World War, codenamed Alberich after the invisible guardian dwarf of the Rhinegold treasure from Richard Wagner's Der Ring des Nibelungen music dramas. The ...
