Tight Vector Bin Packing with Few Small Items via Fast Exact Matching in Multigraphs
Adam Teodor Polak, Alexandra Anna Lassota
We solve the Bin Packing problem in O^*(2^k) time, where k is the number of items less or equal to one third of the bin capacity. This parameter measures the distance from the polynomially solvable case of only large (i.e., greater than one third) items. O ...
Schloss Dagstuhl – Leibniz-Zentrum fur Informatik2022A Computational Comparison Between Isogeometric Analysis and Spectral Element Methods: Accuracy and Spectral Properties
Alfio Quarteroni, Ondine Gabrielle Chanon
In this paper, we carry out a systematic comparison between the theoretical properties of Spectral Element Methods and NURBS-based Isogeometric Analysis in its basic form, that is in the framework of the Galerkin method, for the approximation of the Poisso ...
SPRINGER/PLENUM PUBLISHERS2020Stress intensity factors for axial semi-elliptical surface cracks and embedded elliptical cracks at longitudinal butt welded joints of steel-lined pressure tunnels and shafts considering weld shape
Anton Schleiss, Pedro Filipe De Almeida Manso, Alexandre Jean Pachoud
When for steel liners of pressure tunnels and shafts high-strength steels are used, welded joints are subject to the risk of hydrogen induced cold-cracking in the base material. Longitudinal butt welded joints are critical regions as they are loaded transv ...
Elsevier2017Smooth Shapes with Spherical Topology: Beyond Traditional Modeling, Efficient Deformation, and Interaction
Michaël Unser, Pablo Garcia-Amorena Garcia, Daniel Andreas Schmitter
Existing shape models with spherical topology are typically designed either in the discrete domain using interpolating polygon meshes or in the continuous domain using smooth but non-interpolating schemes such as subdivision or NURBS. Both polygon models a ...

Michaël Unser, Pablo Garcia-Amorena Garcia, Daniel Andreas Schmitter
Existing shape models with spherical topology are typically designed either in the discrete domain using interpolating polygon meshes or in the continuous domain using smooth but non-interpolating schemes such as NURBS. Polygon models and subdivision metho ...
ACM2016A Rescaled Localized Radial Basis Function Interpolation On Non-Cartesian And Nonconforming Grids
Alfio Quarteroni, Simone Deparis, Davide Forti
In this paper we propose a rescaled localized radial basis function (RL-RBF) interpolation method, based on the use of compactly supported radial basis functions. Starting from the classical RBF interpolation technique, we introduce a rescaling that allows ...
Siam Publications2014Mixing patterns from the groups Sigma(n phi)
We survey the mixing patterns which can be derived from the discrete groups Sigma(36 x 3), Sigma( 72 x 3), Sigma(216 x 3) and Sigma(360 x 3), if these are broken to Abelian subgroups G(e) and G(nu) in the charged lepton and neutrino sector, respectively. S ...
Iop Publishing Ltd2014Some algebro-geometric solutions for the coupled modified Kadomtsev-Petviashvili equations arising from the Neumann type systems
A treatment is described for getting some algebro-geometric solutions of the coupled modified Kadomtsev-Petviashvili (cmKP) equations and a hierarchy of 1 + 1 dimensional integrable nonlinear evolution equations (INLEEs) by using the Neumann type systems t ...
American Institute of Physics2012On the use of graphs in discrete tomography
Dominique de Werra, Bernard Ries
In this tutorial paper, we consider the basic image reconstruction problem which stems from discrete tomography. We derive a graph theoretical model and we explore some variations and extensions of this model. This allows us to establish connections with s ...
2010Graph coloring with cardinality constraints on the neighborhoods
Dominique de Werra, Bernard Ries
Extensions and variations of the basic problem of graph coloring are introduced. The problem consists essentially in finding in a graph G a k-coloring, i.e., a partition V-1,...,V-k of the vertex set of G such that, for some specified neighborhood (N) over ...
