Sensitive Demonstration of the Twin-Core Couplers including Kerr Law Non-Linearity via Beta Derivative Evolution
PublikacjaTo obtain new solitary wave solutions for non-linear directional couplers using optical meta-materials, a new extended direct algebraic technique (EDAT) is used. This model investigates solitary wave propagation inside a fiber. As a result, twin couplers are the subject of this study. Kerr law is the sort of non-linearity addressed there. Because it offers solutions to problems with large tails or infinite fluctuations, the resulting...

Towards a classification of networks with asymmetric inputs
PublikacjaCoupled cell systems associated with a coupled cell network are determined by (smooth) vector fields that are consistent with the network structure. Here, we follow the formalisms of Stewart et al (2003 SIAM J. Appl. Dyn. Syst. 2, 609–646), Golubitsky et al (2005 SIAM J. Appl. Dyn. Syst. 4, 78–100) and Field (2004 Dyn. Syst. 19, 217–243). It is known that two non-isomorphic n-cell coupled networks can determine the same sets of...

Organic carbon fluxes of a glacier surface: a case study of Foxfonna, a small Arctic glacier
PublikacjaArctic glaciers are rapidly responding to global warming by releasing organic carbon (OC) to downstream ecosystems. The glacier surface is arguably the most biologically active and biodiverse glacial habitat and therefore the site of important OC transformation and storage, although rates and magnitudes are poorly constrained. In this paper, we present measurements of OC fluxes associated with atmospheric deposition, ice melt,...

Simulation-driven size-reduction-oriented design of multi-band antennas by means of response features
PublikacjaThis study addresses the problem of explicit size reduction of multi-band antennas by means of simulation-driven optimisation. The principal difficulty of electromagnetic (EM)-based miniaturisation of multi-band antennas is that several resonances have to be controlled independently (both in terms of their frequency allocation and depth) while attempting to reduce physical dimensions of the structure at hand. The design method...

Między XIX a XXI wiekiem. Obecny stan filozofii i jego nieco zapomniane źródła
PublikacjaW XiX wieku rozpoczął się kryzys filozofii. Przestała ona odgrywać wiodącą rolę na uniwersytecie i impulsy płynące z jej strony nie odgrywały już większej roli. Wskutek ogromnego rozwoju nauk przyrodniczych praktyka naukowa staje się afilozoficzna i do samej filozofii zaczęła odnosić się wrogo. Filozofia swój zasadniczy przedmiot zainteresowań – byt, obszar tradycyjnej metafizyki, musiała oddać szybko rozwijającym się naukom szczegółowym...
