The classical scheme of biogeochemical zones (BGZ) is known to be an oversimplification of the microbial processes that occur in organic-rich marine sediments. Results from a coupled deployment of pore-water gel probes in Loch Duich, Scotland, provide direct evidence for rapid recycling within the iron reduction (FeR) and sulphate reduction (SR) zones. High resolution porewater profiles obtaine...

Krylov subspace methods have become very popular, not only for solving large scale linear systems, but also in the area of model order reduction. It is also well known that the performance of iterative solution techniques depends crucially on the choice of preconditioning matrix. Within the area of model order reduction, the concept of preconditioning has not yet been introduced. However, recen...

This paper proposes a new SAT-based algorithm for recovering area in technology mapping. The algorithm considers a sequence of relatively small overlapping regions of a mapped network and computes an improved mapping of each using a SAT solver. Delay constraints are taken into account by interfacing the SAT solver with a timer. Experimental results are given for mapping into 6LUTs. An average r...

Multimode systems have emerged as an areaand power-efficient platform for implementing multiple timewise mutually exclusive digital signal processing (DSP) applications in a single hardware space. This paper presents a design methodology for integrating flexible components and controllers into primarily fixed logic multimode DSP systems, thereby increasing their overall efficiency and implement...

Over the years, issue of improving urban environment remains relevant, especially in design children's playgrounds and recreation areas. In addition to analysis available vegetation terrain conditions, noise pollution should also be considered order take into account suitable measures for its reduction. The most effective ecological aesthetic method is establishment plant barriers reduce discom...
