  • Bruening, Erwin; Chruściński, Dariusz; Petruccione, Francesco (2008-10-14)
    A parametrization of density operators for bipartite quantum systems is proposed. It is based on the particular parametrization of the unitary group found recently by Jarlskog. It is expected that this parametrization will ...
  • Drążkowska, Joanna; Hanasz, Michał; Kowalik, Kacper (2010-08-30)
    Piernik is a multi-fluid grid magnetohydrodynamic (MHD) code based on the Relaxing Total Variation Diminishing (RTVD) conservative scheme. The original code has been extended by addition of dust described within the particle ...
  • Chruściński, Dariusz (2004-06-04)
    We propose a new formula for the adiabatic Berry phase which is based on phase-space formulation of quantum mechanics. This approach sheds a new light into the correspondence between classical and quantum adiabatic phases ...
  • Strzałkowski, Karol; Firszt, Franciszek; Marasek, Agnieszka (Elsevier, 2017)
    In this paper optical properties of Zn1-x-yBexMnySe mixed semiconductors were studied as a function of both, temperature and excitation power. The crystals under investigation were grown by the high-pressure, high-temperature ...
  • Hanasz, Michał; Kowalik, Kacper; Wóltański, Dominik; Pawłaszek, Rafał (2008-12-11)
    We present a new multi-fluid, grid MHD code PIERNIK, which is based on the Relaxing TVD scheme. The original scheme has been extended by an addition of dynamically independent, but interacting fluids: dust and a diffusive ...
  • Hanasz, Michał; Kowalik, Kacper; Wóltański, Dominik; Pawłaszek, Rafał; Kornet, Kacper (2008-12-15)
    We present a new multi-fluid, grid MHD code PIERNIK, which is based on the Relaxing TVD scheme (Jin and Xin, 1995). The original scheme (see Trac & Pen (2003) and Pen et al. (2003)) has been extended by an addition of ...

  • Morawiec, Seweryn; Mendes, Manuel J.; Priolo, Francesco; Crupi, Isodiana (2020-10-01)
    The optical properties of localized surface plasmon resonances (LSPR) sustained by self-assembled silver nanoparticles are of great interest for enhancing light trapping in thin film photovoltaics. First, we report on a ...

  • Sokolov, Oleksandr; Mreła, Aleksandra; Józefowicz, Mateusz; Rydel, Krzysztof; Meszyński, Sebastian (2019-03-30)
    The article presents issues related to the positioning of mobile robots in a closed area. The method of positioning using photogrammetry methods based on the analysis of specially created unique square-shaped markers is ...
  • Piwiński, Mariusz (Wydział Matematyki i Informatyki Uniwersytetu Mikołaja Kopernika w Toruniu, Polskie Towarzystwo Informatyczne, 2008)
    Życie w społeczeństwie informatycznym skutkuje wszechobecnością komputerów. Stały się one niezbędnym narzędziem wykorzystywanym w codziennej pracy zawodowej oraz w życiu prywatnym. Szybki rozwój technologiczny sprawił, że ...
  • Erwiński, Krystian; Paprocki, Marcin; Wawrzak, Andrzej; Grzesiak, Lech M. (2016-11-12)
    Generation of a time-optimal feedrate profile for CNC machines has received significant attention in recent years. Most methods focus on achieving maximum allowable feedrate with constrained axial acceleration and jerk ...
  • Chruściński, Dariusz (2005-06-11)
    We show that quantum Bateman's system which arises in the quantization of a damped harmonic oscillator is equivalent to a quantum problem with 2D parabolic potential barrier known also as 2D inverted isotropic oscillator. ...
  • Chruściński, Dariusz; Jurkowski, Jacek (2005-06-01)
    Quantization of a damped harmonic oscillator leads to so called Bateman's dual system. The corresponding Bateman's Hamiltonian, being a self-adjoint operator, displays the discrete family of complex eigenvalues. We show ...
  • Chruściński, Dariusz (2003-01-17)
    We show that the quantization of a simple damped system leads to a self-adjoint Hamiltonian with a family of complex generalized eigenvalues. It turns out that they correspond to the poles of energy eigenvectors when ...
  • Chruściński, Dariusz (2003-07-23)
    We investigate the resonant states for the parabolic potential barrier known also as inverted or reversed oscillator. They correspond to the poles of meromorphic continuation of the resolvent operator to the complex energy ...
  • Chruściński, Dariusz; Jurkowski, Jacek; Kossakowski, Andrzej (2007-10-10)
    We construct a large class of bipartite M x N quantum states which defines a proper subset of states with positive partial transposes (PPT). Any state from this class is PPT but the positivity of its partial transposition ...
  • Chruścińska, Alicja; Przegiętka, Krzysztof (WIND, 2005)
    In spite of many years of research our knowledge of the traps responsible for the OSL in quartz is not complete. Many papers report the complexity of this signal, determine its components and discuss their usefulness for ...
  • Erwiński, Krystian; Wawrzak, Andrzej; Paprocki, Marcin (2023-03-13)
    In this article, a NURBS toolpath feedrate profile generation algorithm for a biaxial linear motor control system is presented. High achievable velocities and accelerations of linear motor machines present new computational ...
