Oxygen partial pressure and temperature dependence of low frequency capacitance of symmetrical porous Sr0.86Ti0.65Fe0.35O3 electrode on CGO substrate
Open Research DataThis dataset contains values of low frequency capacitance at different temperatures (800 °C, 750 °C, 700 °C, 650 °C and 600 °C) and oxygen partial pressures (20%, 10%, 5%, 1%, 0.1% and 0.01% pO2) of symmetrical Sr0.86Ti0.65Fe0.35O3 electrode sintered at 1000 °C. This values were obtained by fitting each measured impedance spectra by electrical equivalent...

The corrosion studies of 3,4,5-trihydroxybenzoic acid as an effective corrosion inhibitor of low alloy steel
Open Research DataThe dataset contains the electrochemical studies evaluating if gallic acid is a corrosion inhibitor for low alloy steel. Three measurements were carried out each case; corrosion potential (label ecorr), electrochemical impedance spectroscopy (label eis) and cyclic polarization (label cp). The measurements were carried out in sodium chloride, acidified...

Driver influence on tyre/road noise generated by vehicle in road traffic.Wpływ kierowcy na hałas generowany przez pojazd w ruchu drogowym.
PublicationW pracy omówiono wkływ stylu jazdy kierowcy oraz stanu technicznego wybranych zespołów pojazdu na jego hałas generowany w ruchu drogowym. Wpływ został przeanalizowany w aspekcie takich parametrów, jak: prędkość jazdy, obciążenie kół siłami wzdłużnumi i poprzecznymi, ciśnienie w ogumieniu, obciążenie pionowe kół, zbieżność i inne.

Analysis of the selection of low temperature medium for a turbine power plant using ocean thermal energy (OTEC)
PublicationThe paper presents the results and conclusions of numerical calculations modelled in the EES program of a closed OTEC cycle. The following mediums were analysed: ammonia, R32, R41, R404a, R407c, R410a, R423a, R500, R502, R507a and R114, R152a, R234fa, R600, R1234yf, R1234ze. Analogous assumptions were adopted as in the ORC cycle with heat regeneration for dry refrigerants without regeneration for wet refrigerants. Each of them...

Improved RSS-Based DoA Estimation Accuracy in Low-Profile ESPAR Antenna Using SVM Approach
PublicationIn this paper, we have shown how the overall performance of direction-of-arrival (DoA) estimation using lowprofile electronically steerable parasitic array radiator (ESPAR) antenna, which has been proposed for Internet of Things (IoT) applications, can significantly be improved when support vector machine (SVM) approach is applied. Because the SVM-based DoA estimation method used herein relies solely...
