  - Year 2022

  Design of contemporary antenna systems is a challenging endeavor. The difficulties are partially rooted in stringent specifications imposed on both electrical and field characteristics, demands concerning various functionalities, but also constraints imposed upon the physical size of the radiators. Furthermore, conducting the design process at the level of full-wave electromagnetic (EM) simulations, otherwise dictated by reliability,...

  - International Journal of Enterprise Information Systems - Year 2006

  W artykule opisano rolę modelowania opisowego w ekonomicznych systemach złożonych w kontekście trzech funkcji naukowych: opisu, wyjaśniania i przewidywania. Fazy dekompozycji i opisu jakościowego modelowanych systemów, w tym ekonomicznych, są nieodzowne w całym procesie budowania modelu.

  - INTERNATIONAL JOURNAL OF NUMERICAL MODELLING-ELECTRONIC NETWORKS DEVICES AND FIELDS - Year 2020

  The design of modern‐day high‐frequency devices and circuits, including microwave/RF, antenna and photonic components, historically has relied on full‐wave electromagnetic (EM) simulation tools. Initially used for design verification, EM simulations are nowadays used in the design process itself, for example, for finding optimum values of geometry and/or material parameters of the structures of interest. In a growing number of...

  - IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES - Year 2021

  Full-wave electromagnetic (EM) analysis is one of the most important tools in the design of modern microwave components and systems. EM simulation permits reliable evaluation of circuits at the presence of cross-coupling effects or substrate anisotropy, as well as for accounting for interactions with the immediate environment. However, repetitive analyses required by EM-driven procedures, such as parametric optimization or statistical...

  Model mięśnia szkieletowego poprzecznie prążkowanego został przedstawiony jako szeregowe połączenie aktywnych i pasywnych odcinków reologicznych. Zasymulowane zostały: skurcze pojedyncze, niecałkowity skurcz tężcowy, całkowity skurcz tężcowy. Model zespołu mięśni w układzie ramię-przedramię opisu-je zmianę kąta obrotu przedramienia względem nieruchomego ramienia. Pobudzając zginacze i prostowniki był zasymulowany obrót przedramienia.

• Systems, Environments, and Soliton Rate Equations: Toward Realistic Modeling

  Publication

  • M. Kuna

  - Foundations of Science - Year 2019

  In order to solve a system of nonlinear rate equations one can try to use some soliton methods. The procedure involves three steps: (1) find a ‘Lax representation’ where all the kinetic variables are combined into a single matrix ρ, all the kinetic constants are encoded in a matrix H; (2) find a Darboux–Bäcklund dressing transformation for the Lax representation iρ˙=[H,f(ρ)], where f models a time-dependent environment; (3) find...
