  - Year 2018

  The objective of this paper is to propose a graph model that would be suitable for providing OLAP features on graph databases. The included features allow for a multidimensional and multilevel view on data and support analytical queries on operational and historical graph data. In contrast to many existing approaches tailored for static graphs, the paper addresses the issue for the changing graph schema. The model, named Evolution...

• Combining Road Network Data from OpenStreetMap with an Authoritative Database

  Publication

  • G. Szwoch

  - Journal of Transportation Engineering, Part A: Systems - Year 2019

  Computer modeling of road networks requires detailed and up-to-date dataset. This paper proposes a method of combining authoritative databases with OpenStreetMap (OSM) system. The complete route is established by finding paths in the graph constructed from partial data obtained from OSM. In order to correlate data from both sources, a method of coordinate conversion is proposed. The algorithm queries road data from OSM and provides...

• A Systematic Search for New Coupling Schemes of Cross-Coupled Resonator Bandpass Filters

  Publication

  • A. Lamęcki

  - RADIOENGINEERING - Year 2014

  In this paper, a systematic approach to an extensive search for topologies of cross-coupled filters with generalized Chebyshev response is presented. The technique applies graph theory to find unique, nonisomorphic filter configurations, and tests whether a specific frequency response can be realized in a given set of topologies. The results of the search are then stored in a database of possible filter configurations.
