Width shrinkage occurs immediately after impregnation with caustic soda as a result of swelling of the cotton. Edge thickening changes the appearance of the stitchstructure and causes variations in colour (usually lighter). Whereas in the past, patterns were adapted totake this into account and ...

Branchwidth and treewidth are connectivity parameters of graphs, and whenever one of these parameters is bounded by some fixed constant on a class of graphs, then so is the other [16]. Since many graph problems that are in general NP-hard can be solved in linear time on such classes of...
Glass wool is a kind of glass fiber and a kind of artificial inorganic wool. Adopting such natural ores as quartz sand ,limestone ,etc as the main ingredients and then coordinating with some chemical materials such as soda ash and borax,etc,the glass is hence melted ...
This invention is an integrally molded display floor for a gravity feed display tray where the floor has no integrally molded side walls extending upward but has a plurality of longitudinal ribs which can receive upward extending partitions which are releasably attachable to the floor and extend lon...
We can reduce this problem to the constrained color spanning CSCA problem with two colors in O(n) time as follows. Let o be the origin of the coordinate system. For each members xi∈X, put a red point pi on the x-axis (in either side of o) such that d(o,pi)=xi. Similarly, ...
[11, SODA 2014], who provided single-exponential algorithms on general graphs for most connectivity problems that were known to be solvable in single-exponential time on topologically constrained graphs. In this article we further investigate the role of planarity in connectivity problems parameterized ...
These problems are dominating set, list- q-coloring with costs (fixed number of colors q) and chromatic number. They are all known to be NP-hard in general. We show that all these problems (except edge-coloring) can be solved in polynomial time on graphs with clique-width bounded by ...
2. Theoretical Analyses The quasi-three-level emission wavelengths of Nd:YVO4 (neodymium-doped yttrium vanadate) and Nd:GdVO4 (neodymium-doped gadolinium vanadate) are 914 nm and 912 nm, respectively. Both materials can serve as gain media for deep-ultraviolet light operating at a wavelength of...
