  • M. Turzyński
  • D. Świsulski

  - Przegląd Elektrotechniczny - Year 2015

  A top-gated Graphene Field-Effect Transistor (GFET) suitable for electronic sensing applications was modelled. The applied simulation method reproduces correctly the output transfer GFET characteristics and allows to investigate doping effect caused by different physical, chemical or biological factors. The appearance of additional charge in the system results in the shift of the current-voltage characteristic. This feature could...

  - JOURNAL OF PHYSICS B-ATOMIC MOLECULAR AND OPTICAL PHYSICS - Year 2015

  We present the results of experimental and theoretical study on electron collisions with a 1,2-butadiene (H2C=C=CHCH3) molecule. Absolute grand-total cross sections (TCSs) were measured using a linear electron-transmission method for collision energies in the 0.5–300 eV range. Two distinct features in the TCS energy curve were detected: a narrow peak located at 2.3 eV and a broad enhancement centered around 9 eV. We attributed...

  - Journal of Physics : Conference Series - Year 2020

  Electron attachment to molecular target can lead to a variety of negative fragment ions. We experi- mentally probe the main dissociative electron attachment channels in furan-2-carboxylic acid (C3H3O2 − COOH) - a molecular target composed of two important structural units: a furan ring and a carboxylic group. In our studies we utilise nearly mono-energetic electrons at electron energies from 0 eV up to 15 eV. Our detection setup...

  We present cross sections from a joint experimental and theoretical study on elastic electron scattering from hexafluoropropene (C3F6) in the gas phase. The experimental results, using low energy electron spectroscopy, were obtained at incident electron energies of 0.5, 1, 1.5, 2, 3, 4, 5, 6, 10, 12, 15 and 20 eV, for scattering angles ranging from 10°to 130°. The theoretical method used in the computation of the integral, momentum...

• Research on water lubricated main shaft bearings in conditions of improper lubrication and cooling conducted on high torque real-life scale bush test rig

  Publication

  • A. Barszczewska
  • W. Litwin
  • J. Sadowski

  - Year 2017

  Water lubricated polymer bushes find increasingly popular use in the sliding bearings of marine propellers, water turbines and pump shafts. Such popularity is partly due to their simple construction which also means relatively affordable price. In addition, properly designed and installed water lubricated bearings may well last for over a decade. However, in practical experience one may also observe cases of rapid wear...

• Spin-Orbit Coupling Matrix Elements in the KRb Molecule

  • D. Kędziera
  • J. Sienkiewicz

  The allowed 190 spin-orbit coupling (SOC) matrix elements have been calculated for the singlet (s) and triplet (t) Sigma+ (S+), Pi (P), and Delta (D) electronic states of the KRb molecule. These SOCs are needed for investigations of areas connected with classical spectroscopy, deperturbation analysis of the observed spectra, atom-molecule and molecule-molecule...

  Niezawodna transmisja danych w wielodrogowym i niestacjonarnym płytkim kanale podwodnym wymaga zastosowania efektywnej techniki modulacji oraz equalizacji adaptacyjnej. W zaproponowanym artykule w systemie transmisji danych zastosowano modulację OFDM oraz equalizację adaptacyjną opartą o filtrację Kalmana. Ponadto zaimplementowano dwie techniki kodowania: FEC w celu eliminacji błędów transmisji oraz kodowanie pseudoszumowe, którego...

  A method for encoding wideband speech signal employing standardized narrowband speech codecs is presented as well as experimental results concerning detection of tonal spectral components. The speech signal sampled with a higher sampling rate than it is suitable for narrowband coding algorithm is compressed in order to decrease the amount of samples. Next, the time-compressed representation of a signal is encoded using a narrowband...

  W referacie przedstawiono hybrydowy kodek mowy dla zastosowan w komunikacji VoIP wykorzystujący kodowanie parametryczne i percetualne. Sygnał mowy jest dzielony na składowe dźwięczne, które podlegają kodowania perceptualnemu, składowe bezdźwięczne, które kodowane są metodą parametryczną oraz transjenty, które nie są kodowane żadną stratną metodą. Dodatkowo przedstawiono architekturę kodeka, w której perceptualnie kodowana i przesyłana...
