For the past ten years, small hydropower plant (SHP) potential has been greatly affected by environmental legislation that falls under designated areas such as Natura 2000 and the Water Framework Directive. Everyone working in the hydropower field knows how many obstacles are put in the way of the implementation of a hydropower plant. One of the greatest is(More)
In this paper, water sorption behavior of 28 days hardened composites based on hemp hurds and inorganic binder was studied. Two kinds of absorption tests on dried cube specimens in deionized water bath at laboratory temperature were performed. Short-term (after one hour water immersion) and long-term (up to 180 days) water absorption tests were carried out(More)
The importance of the boundary-value problems (BVP) for engineering applications attracts and motivates continuous development of fast numerical algorithms for its solution. A number of various approaches have been suggested, such as finite elements methods, fast Fourier transform methods, multigrids methods and difference methods (e.g. [1, 2, 3, 5, 6, 7,(More)
The new imlementation of a parallel ring algorithm for the solution of a spatially one dimensional initial-boundary-value problem for a parabolic equation using an explicit difference method is described. The speed-up function is determined as a ratio between necessary time for realizing the algorithm in a sequentional and parallel case. The algorithm was(More)
