The paper presents a general procedure to solve nume‐ rically optimal control problems with state constraints. It is used in the case, when the simple time discretization of the state equations and expressing the optimal cont‐ rol problem as a nonlinear mathematical programming problem is too coarse. It is based on using in turn two multiple shooting BVP approaches: direct and indirect. The paper...
The paper presents new and improved numerical methods designed for analysis of mechanical systems with uncertain parameters. Uncertain parameters in mechanical systems are described using possibility theory. The main representatives of this theory are fuzzy and interval numbers. Algorithms using interval and fuzzy numbers are incorporated into the analysis. The possibilities and efficiency of suggested...
W artykule przedstawiono metodę obliczania infiltracyjnych ujęć wód podziemnych współpracujących ze złożonym lewarem. Zastosowano numeryczną metodę Newtona-Raphsona do rozwiązywania układów równań nieliniowych. Przedstawiono praktyczne zastosowanie ogólnej metody obliczania złożonych układów lewarów klasycznych dla układu składającego się z 10 studni rozmieszczonych prostoliniowo w warstwie wodonośnej...
