Item Miniature induction sensors for scientific research and objects diagnostics(Видавництво Львівської політехніки, 2012) Nichoga, Vitalij; Pronenko, ViraThis paper presents the design peculiarities of induction sensors for magnetic fields study: the first, for the use in space conditions and the second, for the study of anomalous magnetic fields arising from rails flaws. For both cases the problem of their size minimization while ensuring minimum level of magnetic noise and the required spatial resolution is discussed.Item Application of a magnetic field model above the defect for detection of transverse cracks in the magnetic flaw control of the railway(Видавництво Львівської політехніки, 2012) Nichoga, Vitalij; Storozh, Igor; Vashchyshyn, LiubomyrMethod of signal analysis for magnetic flaw control of the railway is presented.Item Numerical models in bioelectromagnetics(Видавництво Львівської політехніки, 2012) Dlugosz, Tomasz; Nichoga, Vitalij; Trzaska, HubertThe paper deals with problem of possible simplification of numerical models, especially in bioelectromagnetics, in order to shorten the calculation time and necessary RAM volume. Presented estimations confirm usefulness of presented idea.Item Analysis of defectoscopic signals using the wavelet, adapted to detection signals from Transverse cracks in the head of a Rail(Видавництво Львівської політехніки, 2012) Vashchyshyn, Liubomyr; Nichoga, Vitalij; Storozh, IgorAnalysis of the signals obtained at magnetodynamic flaw detection of the railway tracks by the continuous wavelet transform (CWT) using adapted to detection some defects wavelet is considered.Item Research of possibility of application of scaled functions for the analysis of signals of defect detection of railway rails(Видавництво Львівської політехніки, 2010) Nichoga, Vitalij; Ivanchuk, Viktor; Storozh, IhorThe method of analysis of signals of magneticdynamical crack detection in railway rails is described.Item Quasi-spherical EMF polarization(Видавництво Львівської політехніки, 2010) Bienkowski, Pawel; Dlugosz, Tomasz; Nichoga, Vitalij; Trzaska, HubertThe paper presents a way of electromagnetic field (EMF) generation that has three spatial components, i.e.: EMF spherical polarized. Such a field is useful in EM susceptibility investigations, especially that of freely moving objects, in electromagnetic compatibility, bioelectromagnetics, etc.Item An analysis of potential performance of passive TDOA systems with a short baseline(Видавництво Львівської політехніки, 2010) Antonyuk, Volodymyr; Voronkov, Sergey; Grudzinski, Eugeniusz; Kavalec, Adam; Nichoga, Vitalij; Prudyus, Ivan; Sumyk, Markian
