  • Domination subdivision and domination multisubdivision numbers of graphs

    Publikacja

    - Discussiones Mathematicae Graph Theory - Rok 2019

    The domination subdivision number sd(G) of a graph G is the minimum number of edges that must be subdivided (where an edge can be subdivided at most once) in order to increase the domination number of G. It has been shown [10] that sd(T)<=3 for any tree T. We prove that the decision problem of the domination subdivision number is NP-complete even for bipartite graphs. For this reason we define the domination multisubdivision number...

  • Rapid antenna design optimization using shape-preserving response prediction

    Publikacja

    - Bulletin of the Polish Academy of Sciences-Technical Sciences - Rok 2012

    An approach to rapid optimization of antennas using the shape-preserving response-prediction (SPRP) technique and coarsediscretization electromagnetic (EM) simulations (as a low-fidelity model) is presented. SPRP allows us to estimate the response of the high-fidelity EM antenna model, e.g., its reflection coefficient versus frequency, using the properly selected set of so-called characteristic points of the low-fidelity model...

  • Simplified saturation modelling in three-leg power transformer for the system stability analisys

    Publikacja

    - Rok 2016

    The paper presents a simplified method for modelling non-linearity of the magnetic circuit of the power transformer.
