  • Duch, Włodzisław (Springer, 2013)
  • Duch, Włodzisław; Szymański, Julian (Springer, 2012)
    Visualization of Wikipedia categories using Self Organizing Maps shows an overview of categories and their relations, helping to narrow down search domains. Selecting particular neurons this approach enables retrieval ...
  • Piwiński, Mariusz (Wydawnictwo Naukowe UMK, 2017)
    Obecnie mamy do czynienia z dynamicznym rozwojem sieci bezprzewodowych wykorzystujących technologie Wi-Fi. Przejawia się to między innymi w postaci pojawiających się rozszerzeń standardu IEEE 802.11 (np. n, ac, ad) ...
  • Piwiński, Mariusz; Marczak, Grzegorz (Wydawnictwo Naukowe Uniwersytet Mikołaja Kopernika, 2014)
    Obecnie mamy do czynienia z coraz większym rozwojem sieci bezprzewodowych wykorzystujących technologię Wi-Fi, a w szczególności standardy IEEE 802.11. Jednocześnie lawinowy wzrost ilości urządzeń podłączanych do sieci ...
  • Piwiński, Mariusz (Wydawnictwo Naukowe Uniwersytetu Mikołaja Kopernika, 2015)
    Korzystanie z zasobów Internetu obecnie stało się rzeczą tak naturalną, iż wiele osób nie może sobie wyobrazić dnia bez dostępu do tzw. „super sieci”. Powszechnie panujący pogląd, iż nie trzeba rozumieć jak działa technologia, ...
  • Piwiński, Mariusz (Wydawnictwo Naukowe Uniwersytetu Mikołaja Kopernika, 2018-07)
    Sieci komputerowe stanowią jeden z najszybciej rozwijających się działów technologii informacyjno-komunikacyjnych ICT (ang. Information and Communication Technologies), które w błyskawiczny sposób z rozwiązań typowo ...
  • Duch, Włodzisław (Polish Academy of Sciences, 2000)
    Similarity-based methods (SBM) are a generalization of the minimal distance (MD) methods which form a basis of several machine learning and pattern recognition methods. Investigation of similarity leads to a fruitful ...
  • Duch, Włodzisław; Dobosz, Krzysztof; Mikołajewski, Dariusz; Wójcik, Grzegorz M. (AGH University of Science and Technology, 2013)
    Diversity of symptoms in autism dictates a broad definition of Autism Spectrum of Disorders(ASD). Each year percentage of children diagnosed with ASD is growing. One common diag-nostic feature in individuals with ASD is ...
  • Balter, Aleksander (Marcel Dekker, 1991-01-01)
    The loss of transparency of the ocular lens is caused by the increase of light scattering as a result of structural changes and by the increased absorption of the visible light due to the accumulation of pigments. Following ...
  • Chruściński, Dariusz; Kossakowski, Andrzej; Sarbicki, Gniewomir (2009-08-19)
    It is shown that entanglement witnesses constructed via the family of spectral conditions are decomposable, i.e. cannot be used to detect bound entanglement. It supports several observations that bound entanglement reveals ...
  • Chruściński, Dariusz; Kossakowski, Andrzej (2008-09-29)
    We provide a partial classification of positive linear maps in matrix algebras which is based on a family of spectral conditions. This construction generalizes celebrated Choi example of a map which is positive but not ...
  • Chruściński, Dariusz (2004-03-15)
    We show that a single-mode squeeze operator S(z) being an unitary operator with a purely continuous spectrum gives rise to a family of discrete real generalized eigenvalues. These eigenvalues are closely related to the ...
  • Piątkowski, Dawid; Schmidt, Mikołaj; Twardowska, Magdalena; Nyk, Marcin; Javier, Aizpurua; Maćkowski, Sebastian (MDPI (Multidisciplinary Digital Publishing Institute), 2017-08-04)
    We experimentally demonstrate strong spectral selectivity of plasmonic interaction that occurs between α-NaYF4:Er3+/Yb3+ nanocrystals, which feature two emission bands, and spherical gold nanoparticles, with plasmon ...
  • Wiśniewski, Dariusz; Drozdowski, Winicjusz; Wojtowicz, Andrzej J.; Łempicki, Aleksander; Dorenbos, Pieter; de Haas, Johan T.M.; van Eijk, Carel W.E.; Bos, Adrie J.J. (Instytut Fizyki PAN, 1996-08)
    The present status of the LuAlO3:Ce scintillator is reviewed. Scintillation mechanism of this material is based on capture by Ce3+ of holes and then electrons from their respective bands. Results of spectroscopic and ...
  • Jaskólski, Włodzimierz; Ayuela, Andres (Royal Society of Chemistry, 2019-12-19)
    Gated bilayer graphene exhibits spin-degenerate gapless states with a topological character localized at stacking domain walls. These states allow for one-dimensional currents along the domain walls. We herein demonstrate ...
  • Perucho, Manuel; Marti, Jose-Maria; Hanasz, Michał (2004-07-28)
    In this paper we continue our study of the Kelvin-Helmholtz (KH) instability in relativistic planar jets following the long-term evolution of the numerical simulations which were introduced in Paper I. The models have been ...
  • Perucho, Manuel; Hanasz, Michał; Marti, Jose-Maria; Sol, Helene (2004-07-27)
    The effects of relativistic dynamics and thermodynamics in the development of Kelvin-Helmholtz instabilities in planar, relativistic jets along the early phases (namely linear and saturation phases) of evolution has been ...
  • Perucho, Manuel; Marti, Jose-Maria; Cela, J. M.; Hanasz, Michał; de la Cruz, R.; Rubio, F. (2010-05-24)
    The stable propagation of jets in FRII sources is remarkable if one takes into account that large-scale jets are subjected to potentially highly disruptive three-dimensional (3D) Kelvin-Helmholtz instabilities. Numerical ...
  • Lesch, Harald; Hanasz, Michał (2003-02-08)
    We present a scenario for efficient magnetization of very young galaxies about 0.5 Gigayears after the Big-Bang by a cosmic ray-driven dynamo. These objects experience a phase of strong star formation during this first ...
  • Strzałkowski, Karol; Kulesza, Sławomir; Zakrzewski, Jacek; Maliński, Mirosław (Elsevier, 2014)
    Piezoelectric photoacoustic spectroscopy with a piezoelectric detection has been used for measurements of the amplitude and phase spectra of Zn1-x-yBexMnySe mixed semiconductors. The investigated crystals were grown from ...
