  • Two-phase water-air flow measurement using gamma-ray absorption technique –bubble flow

    Open Research Data
    open access

    The attached datasets contains the measurement results of the air-water flow in a horizontal pipeline. Flow type: bubble flow. The data shows the pulse counts of the two radiometric sets. Each of these kits consisted of a QSA Global Am-241 gamma ray source and a Tesla SKG-1 type NaI(Tl) scintillation probe. The pulses were recorded using a dedicated...

  • A study of nighttime vehicle detection algorithms

    Open Research Data
    version 1.0 open access

    This dataset is from my master's thesis "A study of nighttime vehicle detection algorithms". It contains both raw data and preprocessed dataset ready to use. In the pictures below you can see how images were annotated.

  • Mn-Co nanofilms on nickel foam measured by XPS mehod

    Open Research Data
    open access

    Manganium-Cobaltium based thin films were electrochemically deposited on a Ni based subsrates in a one-step process at −1.1 V vs. Ag/AgCl in an aqueous solution of differently concentrated Mn(NO3)2·4H2O and Co(NO3)2·6H2O with the deposition time limited by charges of 60, 120, and 200 mC at 25 °C. The concentration ratios of Mn(NO3)2·4H2O to Co(NO3)2·6H2O...

  • Manifest prysznicowy: jakiej chciałbym sztuki, wideo, wystawa Wolne pokoje: Fiks, Gdańsk 2019

    Publication

    - Year 2019

    FIKS (wystawa zbiorowa) Przemiany współczesnych społeczeństw i zachwianie poczucia bezpieczeństwa mają swoje odbicie w pewnych zachowaniach jednostek. Wynika to nie rzadko z frustracji, poczucia winy lub lęku. Gdzieś tam na innym poziomie świadomości nawykowe mechanizmy obronne niekoniecznie muszą być patologiczne. Codzine rytualy, metody, różnorodność osobistych tarczy, systemów i amuletów, fazy, cykle, niekończący sie kołowrotek. Zwykły...

  • Non-Newtonian lubrication of human hip joint for unsteady impulsive motion

    Publication

    - SCIENTIFIC PROBLEMS OF MACHINES OPERATION AND MAINTENANCE - Year 2006

    Tematem niniejszej pracy są parametry smarowania lepkosprężystą cieczą synowialną stawu biodrowego człowieka w czasie kilku, kilkunastu a nawet kilkudziesięciu mikrosekund po doznanym urazie. W niniejszej pracy rozpatruje się urazy wywołujące zmniejszenie lub zwiększenie wysokości i zmiany kształtu szczeliny stawu, które to zmiany po pewnym określonym czasie po doznanym urazie mogą zanikać. W konsekwencji takich urazów i to w...

  • Nadzorowanie procesów dynamicznych w układach mechanicznych

    Publication

    - Year 2012

    W monografii przedstawiono istotę i znaczenie problematyki nadzorowania procesów dynamicznych w wybranych układach mechanicznych, pod kątem zapewnienia zamierzonego przebiegu procesu. Temu celowi podporządkowano autorską metodę sterowania optymalnego przy energetycznym wskaźniku jakości względem trajektorii ruchu zadanego, która znalazła zastosowanie do nadzorowania procesów dynamicznych w układach niestacjonarnych o działaniu...

  • Implementation of spatial/polarization diversity for improved-performance circularly polarized multiple-input-multiple-output ultra-wideband antenna

    Publication

    - IEEE Access - Year 2020

    In this paper, spatial and polarization diversities are simultaneously implemented in an ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna to reduce the correlation between the parallel-placed radiators. The keystone of the antenna is systematically modified coplanar ground planes that enable excitation of circular polarization (CP). To realize one sense of circular polarization as well as ultra-wideband operation,...

  • Compressive Sensing Approach to Harmonics Detection in the Ship Electrical Network

    Publication

    - SENSORS - Year 2020

    The contribution of this paper is to show the opportunities for using the compressive sensing (CS) technique for detecting harmonics in a frequency sparse signal. The signal in a ship’s electrical network, polluted by harmonic distortions, can be modeled as a superposition of a small number of sinusoids and the discrete Fourier transform (DFT) basis forms its sparse domain. According to the theory of CS, a signal may be reconstructed...

  • A Study on Emission of Airborne Wear Particles from Car Brake Friction Pairs

    Publication
    • M. Alemani
    • O. Nosko
    • I. Metinoz
    • U. Olofsson

    - SAE International Journal of Materials and Manufacturing - Year 2016

    The emission of airborne wear particles from friction material / cast iron pairs used in car brakes was investigated, paying special attention to the influence of temperature. Five low-metallic materials and one non-asbestos organic material were tested using a pin-on-disc machine. The machine was placed in a sealed chamber to allow airborne particle collection. The concentration and size distribution of 0.0056 to 10 μm particles...
