... tolerant in nature, hence the name: opportunistic and delay-tolerant networks. Many applications of opportunistic and delay-tolerant networks are b eing actively studied, for example, networks purely ... terms of their fully decentralized design making them extremely robust. They also offer the potential for huge bandwidth gains in contrast to other forms of networks (e.g.,...

... different time splitting patterns and two- or three-band motion-compensated temporal filtering (MCTF). Then, the latter schemes are extended with sys- tematic lossy description coding where the original ... methodology is instantiated onto the sys- tem. It is demonstrated that the proposed solution has little impact on the average performance, while it significantly re- duces the run-time comp...

... on the temperature and on its gradient. Under these conditions, the classic heat equation describes su fficiently well the evolution of the temperature in different types of materials. However, this ... recently, the study of max-type difference equation attracted a considerable attention. Although max-type difference equations are relatively simple in form, it is unfortunately extremely difficult...

A variety of time- frequency distributions have been developed to provide efficient analysis of signals with a time-varying spectral content. ... forms o f time-frequency distributions allow us to further expand and diversify their applicability. This special issue aims to help readers to understand how time-frequency distribut...
