  Monitorowano proces korozji zachodzący na stali ST3S w środowisku obojętnym. Wykonane zostały badania harmoniczne techniką intermodulacji częstotliwościowej. W analizie harmonicznej zastosowana została nowa metoda czasowo-częstotliwościowej tzw. transformacji Gabora. Wykazane zostało, że transformacja Gabora może być przydatna w monitorowaniu korozji w warunkach dynamicznych. Transformacja Gabora pozwala na dobrą reprezentację...

• Increasing the lifetime of engineering structures through the use of composite laggings

  Publication

  • E. Mieloszyk
  • A. Milewska
  • M. Abramski

  - Year 2020

  The use of composite laggings prevents concrete (chemical and biological) corrosion. Columns coated with composite or reinforced composite are more resistant to negative environmental impact on concrete or steel. The mechanical properties of the reinforced casing also cause that these types of columns are more resistant to lateral forces. The applied casing limits carbonization of concrete and cyclical freezing and thawing with...

  - IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION - Year 2022

  Geometry parameter tuning is an inherent part of antenna design process. While most often performed in a local sense, it still entails considerable computational expenses when carried out at the level of full-wave electromagnetic (EM) simulation models. Moreover, the optimization outcome may be impaired if good initial design is not available. This paper proposes a novel approach to fast and improved-reliability gradient-based...

  High concentrations of ammonia and nitrite, typical for reject water treatment in the anammox process with the use of high temperatures and pH, may cause free ammonia (FA) inhibition. In this study, the inhibitory effect of FA on anammox process rate was investigated in a bench-scale sequencing batch reactor (SBR) with granular anammox biomass. Results of the study present that the anammox process could be successfully operated...

  This work reports the design of an original class of highly-compact dual-band bandpass filter based on dual-mode waveguide resonators inter-coupled through a novel type of frequency-dependent coupling (FDC). The devised FDC consists of a cross-shaped metallic structure placed in the broad wall of a rectangular waveguide. This FDC produces two additional poles and three extra transmission zeros (TZs). Specifically, each pole is...
