Sparse Finite Elements for Stochastic Elliptic Problems – Higher Order Moments
(2003)ComputingWe define the higher order moments associated to the stochastic solution of an elliptic BVP in D⊂ℝd with stochastic input data. We prove that the k-th moment solves a deterministic problem in D k⊂ℝdk, for which we discuss well-posedness and regularity. We discretize the deterministic k-th moment problem using sparse grids and, exploiting a spline wavelet basis, we propose an efficient algorithm, of logarithmic-linear complexity, for solving ...Journal Article -

Bounds for the first eigenvalue of the elastically supported membrane on convex domains
(2003)Zeitschrift für angewandte Mathematik und PhysikBarta’s principle and gradient bounds for the torsion function are the main tools for deriving lower bounds for the first eigenvalue. The optimal domains are an infinite strip, a disk or an annulus in different situations.Journal Article -
Search for colour reconnection effects in e+e- -> W+W- -> hadrons through particle-flow studies at LEP
(2003)Physics Letters BA search for colour reconnection effects in hadronic decays of W pairs is performed with the L3 detector at centre-of-mass energies between 189 and 209 GeV. The analysis is based on the study of the particle flow between jets associated to the sameW boson and between two different W bosons in qqqq events. The ratio of particle yields in the different interjet regions is found to be sensitive to colour reconnection effects implemented in ...Journal Article
