Description Abstract We analyze one redundant aspect of the encoder for the Lempel-Ziv '77 data compression algorithm. We prove that the number of pointers into the LZ'77 database asymptotically...
Description Strongly chordal graphs were introduced by Farber in 1983, as a restricted class of graphs for which the weighted dominating set problem can be solved in polynomial time; the problem is NP...
Description We discuss how the boundary concept can be used to describe fractal sets. Two examples illustrate this: 1. Polynomial endomorphisms of C2 and their Julia sets; 2. Self-similar fractals...

Description Covering codes, which are sets of Hamming balls which cover the discrete hypercube, have been studied in many settings, including betting on football pools with a fixed number of matches...
Description The presentation has two parts. One is about FDM application in the material process. The other is about FEM application ( only several slides). The diffusion equation of carbon...

Description The thermohaline circulation in the ocean is strongly influenced by dense water formation in polar and marginal seas. Such dense water masses are released into the ocean circulation in the...
