A cutting-pattern, often called just pattern, is an arrangement of small rectangles on the stock sheet. It may be given as a sequence of points (x i,y i), for i in 1,...,m, where (x i,y i) is the bottom-left coordinate of rectangle i. In such a pattern, rectangle i occupies a horizontal segment (x i, x i +w i) and a vertical segment (y i, y i ...
In manufacturing industry, nesting refers to the process of laying out cutting patterns to minimize the raw material waste. [1] Examples include manufacturing parts from flat raw material such as sheet metal, glass sheets, cloth rolls, cutting parts from steel bars, etc. Such process can also be applied to additive manufacturing, such as 3D ...
Techniques include cutting, clipping, punching, tearing, and carving of paper, as well as nalepianki in which multiple layers are glued together. Subject matter includes peacocks , roosters , and other birds; circular or star-shaped medallions ( gwiazdy ); flowers; and annual holidays such as Easter and Christmas.
Cutting-stock problems can be classified in several ways. [1] One way is the dimensionality of the cutting: the above example illustrates a one-dimensional (1D) problem; other industrial applications of 1D occur when cutting pipes, cables, and steel bars. Two-dimensional (2D) problems are encountered in furniture, clothing and glass production.
A joggling or jostling board is a long, pliable board that is supported on each end by wooden stands. The board is springy and a person sitting on it can easily bounce up and down. The board is springy and a person sitting on it can easily bounce up and down.

In geometry, the Weaire–Phelan structure is a three-dimensional structure representing an idealised foam of equal-sized bubbles, with two different shapes. In 1993, Denis Weaire and Robert Phelan found that this structure was a better solution of the Kelvin problem of tiling space by equal volume cells of minimum surface area than the previous best-known solution, the Kelvin structure.
