This is a summary of ve lectures delivered at the CIME course on Advanced Nu merical Approximation of Nonlinear Hyperbolic Equations held in Cetraro Italy on June Following the introductory lecture I which provides a general overview of approximate solution to nonlinear conservation laws the remaining lectures deal with the speci cs of four complementing… (More)

In this article, we propose a unified framework for Quantum–Corrected Drift–Diffusion (QCDD) models in nanoscale semiconductor device simulation. QCDD models are presented as a suitable generalization of the classical Drift–Diffusion (DD) system, each particular model being identified by the constitutive relation for the quantum–correction to the electric… (More)

In this article, we propose a novel discontinuous Galerkin method for convectiondiffusion-reaction problems, characterized by three main properties. The first is that the method is hybridizable; this renders it efficiently implementable and competitive with the main existing methods for these problems. The second is that, when the method uses polynomial… (More)

This article deals with the analysis of the functional iteration, denoted Generalized Gummel Map (GGM), proposed in [11] for the decoupled solution of the Quantum Drift–Diffusion (QDD) model. The solution of the problem is characterized as being a fixed point of the GGM, which permits the establishment of a close link between the theoretical existence… (More)

In vitro tissue engineering is investigated as a potential source of functional tissue constructs for cartilage repair, as well as a model system for controlled studies of cartilage development and function. Among the different kinds of devices for the cultivation of 3D cartilage cell colonies, we consider here polymeric scaffold-based perfusion… (More)

The Cauchy problem for the Poisson-Nernst-Planck/Navier-Stokes model was investigated by the first author in [Transport Theory Statist. Phys. 31 (2002), 333–366], where a local existence-uniqueness theory was demonstrated, based upon Kato’s framework for examining evolution equations. In this article, the existence of a global weak solution is proved to… (More)

A unified and robust mathematical model for compressible and incompressible linear elasticity can be obtained by rephrasing the Herrmann formulation within the Hellinger-Reissner principle. This quasi-optimally converging extension of PEERS (Plane Elasticity Element with Reduced Symmetry) is called Dual-Mixed Hybrid formulation (DMH). Explicit… (More)

A simple and automated solid-phase extraction for the selective and quantitative HPLC analysis of free catecholamines in urine is described. The urinary catecholamines react with diphenylboric acid, giving a complex at pH 8.5 which is strongly retained on a PLRP-S cartridge; elution is accomplished with the same mobile phase used for HPLC analysis.… (More)
