@misc{Peterson_Todd_E._Non-optimal, author={Peterson, Todd E. and Shuster, David B.}, howpublished={online}, publisher={Zielona Góra: Uniwersytet Zielonogórski}, language={eng}, abstract={We investigate two explicit finite element methods for linear scalar first order hyperbolic equations, one using a continuous piecewise-polynomial approximation and one using a discontinuous approximation. Several aspects of the performance of these methods are considered; in particular, the sharpness of some existing error estimates, and crosswind spread estimates. For the discontinuous method, we give a new error estimate for the case of piecewise-constants.}, type={artykuł}, title={Non-optimal behaviour of finite element methods for first order hyperbolic problems}, keywords={sterowanie, sterowanie-teoria, sztuczna inteligencja, matematyka stosowana, informatyka}, }
