Jean-Paul Riopelle to abstract expressionism), in which he used myriad tumultuous cubes and triangles of multicolored elements, facetted with a palette knife, spatula, or trowel, on often large canvases to create powerful atmospheres. The presence of long filaments of paint in his painting from 1948 through the early 1950s has often been seen as resulting from a dripping technique like that of Jackson Pollock. Rather, the creation of such effects came from the act of throwing, with a palette knife or brush, large quantities of paint onto the stretched canvas (positioned vertically). Riopelle's voluminous impasto became just as important as color. His
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
