A discretization scheme applicable to the direct approximation of the velocity variable for either a rst-order system or second-order elliptic equation is proposed in this paper. The scheme is motivated by mixed nite element methods and extends the cell-centered nite diierence and the nite volume element methods to problems with discontinuous coeecients and various boundary conditions. Error es...

We present a model-based monitoring method for dynamic systems that exhibit both discrete and continuous behaviors. MIMIC (Dvorak & Kuipers 1991) uses qualitative and semi-quantitative models to monitor dynamic systems even with incomplete knowledge. Recent advances have improved the quality of semi-quantitative behavior predictions, used observations to refine static envelopes around monotonic...

We present results of a discontinuous Galerkin scheme applied to deterministic computations of the transients for the Boltzmann-Poisson system describing electron transport in semiconductor devices. The collisional term models optical-phonon interactions which become dominant under strong energetic conditions corresponding to nano-scale active regions under applied bias. The proposed numerical ...

We present a reduced formulation for the elastoacoustic scattering problem. The modeling is based on the On Surface Radiation Condition method. It leads to a discrete system which solution is assessed when using Discontinuous Finite Elements.

It is shown that every asymptotically controllable system can be stabilized by means of some (discontinuous) feedback law. One of the contributions of the paper is in deening precisely the meaning of stabilization when the feedback rule is not continuous.

A variety of protein domain predictors were developed to predict protein domain boundaries in recent years, but most of them cannot predict discontinuous domains. Considering nearly 40% of multidomain proteins contain one or more discontinuous domains, we have developed DomEx to enable domain boundary predictors to detect discontinuous domains by assembling the continuous domain segments. Disco...

This paper presents a nonlinear controller design for a DSTATCOM connected to a distribution network with distributed generation (DG) to regulate the line voltage by providing reactive power compensation. The controller is designed based on the partial feedback linearization which transforms the nonlinear system into a reduced-order linear system and an autonomous system whose dynamics are know...
