• The modelling method of discrete-continuous systems

  Publikacja

  • R. Hein

  - Vibrations in Physical Systems - Rok 2014

  The paper introduces a method of discrete-continuous systems modelling. In the proposed method a three-dimensional system is divided into finite elements in only two directions, with the third direction remaining continuous. The thus obtained discrete-continuous model is described by a set of partial differential equations. General difference equations of discrete system are obtained using the rigid finite element method. The limit...

  - IEEE TRANSACTIONS ON INFORMATION THEORY - Rok 2021

  We present some characterizations of characteristic graphs of row and/or column symmetric channels. We also give a polynomial-time algorithm that decides whether there exists a discrete symmetric channel whose characteristic graph is equal to a given input graph. In addition, we show several applications of our results.

• Acceleration of the discrete Green's function computations

  Publikacja

  • T. Stefański

  - Rok 2012

  Results of the acceleration of the 3-D discrete Green's function (DGF) computations on the multicore processor are presented. The code was developed in the multiple precision arithmetic with use of the OpenMP parallel programming interface. As a result, the speedup factor of three orders of magnitude compared to the previous implementation was obtained thus applicability of the DGF in FDTD simulations was significantly improved.

• A DISCRETE-CONTINUOUS METHOD OF MECHANICAL SYSTEM MODELLING

  Publikacja

  • R. Hein

  - Polish Maritime Research - Rok 2017

  The paper describes a discrete-continuous method of dynamic system modelling. The presented approach is hybrid in its nature, as it combines the advantages of spatial discretization methods with those of continuous system modelling methods. In the proposed method, a three-dimensional system is discretised in two directions only, with the third direction remaining continuous. The thus obtained discrete-continuous model is described...

• Accuracy of the discrete Green's function computations

  Publikacja

  • T. Stefański

  - Rok 2012

  This paper discusses the accuracy of the discrete Green's function (DGF) computations. Recently closed-form expression of the DGF and its efficient numerical implementation were presented which facilitate the DGF applications in FDTD simulations of radiation and scattering problems. By carefully comparing the DGF results to those of the FDTD simulation, one can make conclusions about the range of the applicability of the DGF for...
