Description

One central idea behind the openKB4BMS project is to automatically instantiate the knowledge base on already existing configuration data from the underlying automation systems and the integration layer, respectively. Since for all the information representations needed for this project (OPC UA, oBIX, OWL), XML formats exist, XSL transformation (XSLT) is the method of choice. The goal of this task is to extend the already existing oBIX to OWL transformation stylesheet and define a...

Description

The interfaces openKB4BMS provides downwards to the integration and automation layer are currently implemented very rudimentary. Besides the already working oBIX interface, it is planned to extend the Apache Jena-based runtime components by OPC UA client functionality like illustrated in the system architecture figure. This way, the connectivity of openKB4BMS would be significantly increased. To this aim, an existing open source OPC UA client SDK shall be integrated into the...

Description

Mesh coarsening is an important process for reducing the complexity and/or the mesh element count. Simplification reduces memory usage as well as increases the performance of algorithms operating on a simplified mesh. Especially meshes, which where generated based on 3D scans, often have an unnecessary high element count and benefit from surface simplification.

There are several mesh coarsening algorithms available and some of them even are implemented in open source meshing...

Description

In scientific computing, many mesh related algorithms have a great need for meshes with high quality. Although the type of quality of a mesh depends on the algorithm operating on it, most requirements are similar. Especially size and shape of mesh elements is a central topic when speaking of mesh quality. Mesh generators often struggle with constraints and tend to produce low quality mesh elements. To compensate this, mesh optimizer are invented. These algorithms take a mesh and...
