Planar multi-patch domain parameterization via patch adjacency graphs

As a remarkable difference to the existing CAD technology, where shapes are represented by their boundaries, FEM-based isogeometric analysis typically needs a parameterization of the interior of the domain. Due to the strong influence on the accuracy of the analysis, methods for constructing a good parameterization are fundamentally important. The flexibility of single patch representations is ...

Learning Patch-Based Structural Element Models With Hierarchical Palettes Jeroen Chua Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2012 Image patches can be factorized into ‘shapelets’ that describe segmentation patterns, and palettes that describe how to paint the segments. This allows a flexible factorization of local shape (segmen...

Learning Structural Element Patch Models With Hierarchical Palettes: Supplementary material

1. Variational inference and learning We derive the variational inference updates in this section. We use these updates as an E-step in a variational EM framework that is guaranteed to increase a lower bound on the data likelihood. The variational inference updates for our Q-distributions are given below.

Multi-patch and multi-group epidemic models: a new framework.

We develop a multi-patch and multi-group model that captures the dynamics of an infectious disease when the host is structured into an arbitrary number of groups and interacts into an arbitrary number of patches where the infection takes place. In this framework, we model host mobility that depends on its epidemiological status, by a Lagrangian approach. This framework is applied to a general S...
