Using the topological degree of LerayShauder, and Grisvard's results for elliptic equations with mixed boundary conditions, we extend Mock's results for the steadystate Van Roosbroeck system, with the change from Neuman to Dirichlet boundary conditions occuring at a flat angle. Similar results...
The coupled set of nonlinear 2D diffusion equations for donor and acceptor type impurities with initial and appropriated boundary conditions is solved by an implicit locallyone dimensional finite difference method. Numerical experiments have been made to achieve a reasonable tradeoff between the...
We present a new approach to spectrum estimation leading to computationally efficient highresolution estimator. Our approach is based on the orthogonal sum decomposition, and this could be viewed as weighted periodograms averaging.
Two new mixed finite element schemes for discretizing current continuity equations are presented. Together with the good features of the alreadyknown mixed scheme current preservation and good approximation of sharp shapes, they provide Mmatrices, even when a zero order term is present in the...
