    Opis:
    The article discusses the universal current sensor fault detection and compensation mechanism, which can be applied in three-phase power electronics (PE) symmetrical system. The mechanism is based on the assumption that a symmetrical system can be described using different components in the stationary reference frame. The solution given in article as a Cri-base detector was tested in electrical drives with induction motors (IMs) and permanent magnet synchronous motors (PMSMs). This study also proves that the same algorithm can work stable in active rectifier systems. Such an application of this detector has not been previously reported in the literature. The article describes the detection of various types of faults in different phases. The fault-tolerant voltage-oriented control (FTVOC) of an active rectifier is compared with previously described solutions for IMs and PMSMs. By analysing in various types of systems, the work proves the universality of the detector based on Cri markers.

    Opis:
    The article refers to a valid and current research area, which is the role of information technology (IT) in the formation of business sustainability (BS). The main objective of this article is to identify the role of IT in shaping sustainable organization in the context of different, partly conflicting, approaches to BS and empirical verification of the proposed theoretical framework. The article describes key differences between BS approaches in case cognitive logic (reductionist versus integrative logic) and axiological (individualistic-egoistic versus holistic-altruistic axiology) distinction. Theoretical role of IT in shaping integrative logic for BS is identified and presented. The proposed theoretical concept is empirically verified. The verification is based on empirical studies conducted in 400 SMEs operating in Poland in 2017.

    Opis:
    The surface morphology, structure and hydrophobicity of low-and high-molecular weight poly(dimethylsiloxane) (PDMS) fluids physically adsorbed onto multi-walled carbon nanotubes (MWCNTs) at different weight percentages (5, 10, 20 and 40 wt.%), were studied employing X-ray diffraction (XRD), attenuated total reflectanceFouriertransforminfrared spectroscopy (ATR-FTIR), scanning electron microscopy (SEM) and measurements of contact angle with water. It was found that MWCNTs agglomerate forming voids between tubes of a broad range, while adsorption of the polymer from a hexane solution results in the expected wrapping of nanotubes withPDMS chains and, further, in filling voids, as represented by SEM data. ATR-FTIR was used to investigate the possible structural changes in the polymer nanocomposites. Based on the contact anglemeasurementsvia water drop shape analysis,MWCNTs/PDMS nanocomposites were characterizedas astable,superhydrophobic materials with the maximum contact angle (CA) equal to 152°at CPDMS=40wt.%.
