High Order Wellbalanced Finite Volume WENO Schemes for Shallow Water Equation with Moving Water
, 2007
"... A characteristic feature of hyperbolic systems of balance laws is the existence of nontrivial equilibrium solutions, where the effects of convective fluxes and source terms cancel each other. Recently a number of socalled wellbalanced schemes were developed which satisfy a discrete analogue of th ..."

A fast and stable wellbalanced scheme with hydrostatic reconstruction for shallow water flows
 SIAM J. Sci. Comput
"... Abstract. We consider the SaintVenant system for shallow water flows, with nonflat bottom. It is a hyperbolic system of conservation laws that approximately describes various geophysical flows, such as rivers, coastal areas, and oceans when completed with a Coriolis term, or granular flows when com ..."

, as the structure of their numerical truncation errors is generally not compatible with exact physical steady state conditions. This difficulty can be overcome by using the socalled wellbalanced schemes. We describe a general strategy, based on a local hydrostatic reconstruction, that allows us to derive a wellbalanced
ON SOURCE TERMS AND BOUNDARY CONDITIONS USING ARBITRARY HIGH ORDER DISCONTINUOUS GALERKIN SCHEMES
"... This article is devoted to the discretization of source terms and boundary conditions using discontinuous Galerkin schemes with an arbitrary high order of accuracy in space and time for the solution of hyperbolic conservation laws on unstructured triangular meshes. The building block of the method i ..."

into the numerical flux via the solution of the GRP, our very high order accurate method is also able to maintain very well smooth steadystate solutions of PDEs with source terms, similar to the socalled wellbalanced schemes which are usually specially designed for this purpose. Boundary conditions are imposed
The Askeyscheme of hypergeometric orthogonal polynomials and its qanalogue
, 1998
"... We list the socalled Askeyscheme of hypergeometric orthogonal polynomials and we give a qanalogue of this scheme containing basic hypergeometric orthogonal polynomials. In chapter 1 we give the definition, the orthogonality relation, the three term recurrence relation, the second order differenti ..."

Randomized Gossip Algorithms
 IEEE TRANSACTIONS ON INFORMATION THEORY
, 2006
"... Motivated by applications to sensor, peertopeer, and ad hoc networks, we study distributed algorithms, also known as gossip algorithms, for exchanging information and for computing in an arbitrarily connected network of nodes. The topology of such networks changes continuously as new nodes join a ..."

Reconsidering research on learning from media
 Review of Educational Research
, 1983
"... ABSTRACT. Recent metaanalyses and other studies of media's influence on learning are reviewed, Consistent evidence is found for the generalization that there are no learning benefits to be gained from employing any specific medium to deliver instruction. Research showing performance or timesav ..."

Benchmarking Least Squares Support Vector Machine Classifiers
 NEURAL PROCESSING LETTERS
, 2001
"... In Support Vector Machines (SVMs), the solution of the classification problem is characterized by a (convex) quadratic programming (QP) problem. In a modified version of SVMs, called Least Squares SVM classifiers (LSSVMs), a least squares cost function is proposed so as to obtain a linear set of eq ..."

A ”wellbalanced ” finite volume scheme for blood flow simulation
, 2012
"... We are interested in simulating blood flow in arteries with a one dimensional model. Thanks to recent developments in the analysis of hyperbolic system of conservation laws (in the SaintVenant / shallow water equations context) we will perform a simple finite volume scheme. We focus on conservation ..."

on conservation properties of this scheme which were not previously considered. To emphasize the necessity of this scheme, we present how a too simple numerical scheme may induce spurious flows when the basic static shape of the radius changes. On contrary, the proposed scheme is ”wellbalanced”: it preserves
Wellbalanced high order scheme for 2layer shallow water flows
"... In this talk, we present a scheme for the one dimensional twolayer shallow water equations aimed at high order of accuracy and explicit wellbalancing for moving equilibria. The mathematical model we consider neglects effects like friction between and mixture of the two layers, cf. [2]. It may be w ..."
