Relationship between avant-garde art and American pop culture brush strokes and in techniques partially dictated by chance, such as dripping or spilling the paint directly onto the canvas. Examples of this include Jackson Pollock dripping commercial paints on raw canvas to build up complex and tangled skeins of paint into exciting and suggestive linear patterns and Willem de Kooning used extremely vigorous and expressive brush strokes to build up richly colored and textured images. The second category of Abstract Expressionism is represented by a variety of styles ranging from Color field, to Lyrical abstraction; delicate imagery and fluid shapes and fields of color included in works by Clyfford
Water-pouring algorithm Water-pouring algorithm The water-pouring algorithm is a technique used in digital communications systems for allocating power among different channels in multicarrier schemes. It was described by R. C. Gallager in 1968 along with the water-pouring theorem which proves its optimality for channels having Additive White Gaussian Noise (AWGN) and intersymbol interference (ISI). For this reason, it is a standard baseline algorithm for various digital communications systems. The intuition that gives the algorithm its name is to think of the communication medium as if it was some kind of water container with an uneven bottom. Each of the available channels is
