Quadrature on a Spherical Surface Casper H. L. Beentjes

Quasi-Monte Carlo methods applied to tau-leaping in stochastic biological systems

Quasi-Monte Carlo methods have proven to be effective extensions of traditional Monte Carlo methods in, amongst others, problems of quadrature and the sample path simulation of stochastic differential equations. By replacing the random number input stream in a simulation procedure by a low-discrepancy number input stream, variance reductions of several orders have been observed in financial app...

On Short Recurrences in Optimal Krylov Subspace Solvers:

To solve large sparse linear systems of equations computational fast methods are preferable above methods such as GMRES. By exploiting structure of the involved matrix one can in certain cases use short recurrences to create an optimal Krylov subspace method. In this report we explain some of the theory regarding short-recurrence methods for solving linear systems. A central object in this theo...

GlyNest and CASPER: two independent approaches to estimate 1H and 13C NMR shifts of glycans available through a common web-interface

GlyNest and CASPER (www.casper.organ.su.se/casper/) are two independent services aiming to predict (1)H- and (13)C-NMR chemical shifts of glycans. GlyNest estimates chemical shifts of glycans based on a spherical environment encoding scheme for each atom. CASPER is an increment rule-based approach which uses chemical shifts of the free reducing monosaccharides which are altered according to att...

Deposition of Various Shapes Particles on a Rough Surface in Turbulent Flow

An experiment set-up is used to study wall deposition rate of particles on a rough surface in a turbulent channel flow. Deposition velocities for three classes of particles, namely, spherical glass particles, irregular shape polymer particles, and fibrous silicon particles are studied. The particle concentration at the test section was measured with the aid of an isokinetic probe in conjunction...
