  - Advances in Materials Science - Year 2014

  New materials obtained by pyrolysis of gelatine (G) and poly(1,2-dimethylsilazane) (PSN) (weight ratio: G/PSN 70/30) at temperatures 700 and 900 °C were characterized by SEM and Raman spectroscopy. The presence of ceramics influences on the cluster size of the materials. Electrochemical tests were performed by cyclic voltammetry and galvanostatic cyclic polarization. The capacity of G/PSN was 464 and 527 mAh/g for materials pyrolysed...

  - Year 2017

  An influence of a human body position on ECG derived respiration (EDR) signal is presented in the paper. Examinations were performed during deep, suspended and normal breathing for eight people in four different body positions. EDR and thoracic impedance signals were compared using correlation and standard deviation coefficients. Obtained results have shown that it is possible to monitor breath activity of people being in different...

  - Year 2005

  Zbadano hydratację THF na podstawie spektroskopii FTIR drgań HDO oraz H2O. Dane widmowe poddano analizie przy pomocy ilościowej metody widm różnicowych. Ustalono, że w roztworach rozcieńczonych hydratacja THF typu hydrofobowego dominuje nad hydratacją typu elektrofilowego. Scharakteryzowano wodę w otoczce hydratacyjnej THF poprzez jej porównanie z wodą czystą.

  Przygotowano metodą zol-żel warstwy TiO2 na podłożu kwarcowym. Zbadano ich fotoprzewodnictwo w różnych warunkach. Stwierdzono, że fotoprąd w próżni jest o trzy rzędy większy niż w powietrzu. Jako wyjaśnienie zaproponowano absorpcję tlenu na powierzchni warstwy.

• Fractional Order Circuit Elements Derived from Electromagnetism

  Publication

  • T. Stefański
  • J. Gulgowski

  - Year 2019

  In this paper, derivations of fractional-order (FO) circuit-element equations from electromagnetism are presented. Whilst many papers are devoted to FO modelling of electrical circuits, there are no strong foundations for such an approach. Therefore, we investigate relations between the FO electromagnetism and the FO circuit theory. Our derivations start from quasi-static (QS) approximations of Maxwell's equations in media with...

  - Polymer Chemistry - Year 2015

  As part of our ongoing study investigating isohexide-based polyamides, we have synthesized isosorbide(bis(propan-1-amine)) (DAPIS) and studied its reactivity in the polymerization towards fully biobased polyamides. Polycondensation of nylon salts with various contributions of DAPIS afforded a family of homo- and copolyamides, which were characterized using complementary spectroscopic techniques. The chemical structure of the materials...

  A transform codec employing efficient algorithm for detection of spectral tonal components is presented. The tonality measure used in MPEG psychoacoustic model is replaced with the method providing adequate tonality estimates even if the tonal components are deeply frequency modulated. The reliability of hearing threshold estimated using psychoacoustic model with standardized tonality measure and the proposed one is investigated...

  Ciągle wprowadzane standardy odnośne emisji gaz spalinowych determinują rozwój przemysłu motoryzacyjnego oraz stymulują poszukwianie nowych przyjaznych środowiskowo rozwiązań dla transportu drogowego. Jednym z takich rozwiązań było wprowadzenie konwerterów gazów spalinowych w pojazdach mechanicznych które zawierały metali z grupy platynowców (PGM). Obok niezaprzeczalnych korzyści, zastosowanie PGM w konwerterach spalin nie jest...
