    • TESTING THE ACCURACY OF MEASURED VALUES IN CONTINUOUS LONG-TERM GEODETIC MONITORING 

      Autor: Vaněček , Jan; Štroner , Martin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      widespread used method. In this paper, an analysis of the accuracy and its changes over time of the measured values in continuous geodetic monitoring is presented. For the analysis, a set of data measured in the period of ...

    • TESTS ON 10.9 BOLTS UNDER COMBINED TENSION AND SHEAR 

      Autor: Kawohl Katherine, Anne; Lange , Jörg
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      Prior investigations of the load-bearing capacity of bolts during fire have shown differing behaviour between bolts that have been loaded by shear or by tensile loads. A combination of the two loads has not yet been examined ...

    • THE AHARONOV-BOHM HAMILTONIAN WITH TWO VORTICES REVISITED 

      Autor: Košťáková , Petra; Stovicek , Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      We consider an invariant quantum Hamiltonian H = −ΔLB + V in the L2 space based on a Riemannian manifold ˜M with a discrete symmetry group Γ. To any unitary representation Λ of Γ one can relate another operator on M = ˜M ...

    • THE GOODNESS OF SIMULTANEOUS FITS IN ISIS 

      Autor: Kühnel , Matthias; Falkner , Sebastian; Grossberger , Christoph; Ballhausen , Ralf; Dauser , Thomas; Schwarm , Fritz-Walter; Kreykenbohm , Ingo; Nowak A., Michael; Pottschmidt , Katja; Ferrigno , Carlo; Rothschild E., Richard; Martínez-Núñez , Silvia; Torrejón , José Miguel; Fürst , Felix; Klochkov , Dmitry; Staubert , Rüdiger; Kretschmar , Peter; Wilms , Jörn
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      In a previous work, we introduced a tool for analyzing multiple datasets simultaneously, which has been implemented into ISIS. This tool was used to fit many spectra of X-ray binaries. However, the large number of degrees ...

    • THREE-VARIABLE ALTERNATING TRIGONOMETRIC FUNCTIONS AND CORRESPONDING FOURIER TRANSFORMS 

      Autor: Bezubik , Agata; Pošta , Severin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      The common trigonometric functions admit generalizations to any higher dimension, the symmetric, antisymmetric and alternating ones. In this paper, we restrict ourselves to three dimensional generalization only, focusing ...

    • TWO-DIMENSIONAL HYBRIDS WITH MIXED BOUNDARY VALUE PROBLEMS 

      Autor: Szajewska , Marzena; Tereszkiewicz , Agnieszka
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      Boundary value problems are considered on a simplex F in the real Euclidean space R2. The recent discovery of new families of special functions, orthogonal on F, makes it possible to consider not only the Dirichlet or ...

    • ULTRASONIC SOLDERING OF Cu AND Al2O3 CERAMICS BY USE OF Bi-La AND Bi-Ag-La SOLDERS 

      Autor: Koleňák , Roman; Prach , Michal; Kostolný , Igor
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      This work deals with the effect of solder alloying with a small amount of lanthanum on joint formation with metallic and ceramic substrate. The Bi-Ag – based solder with 2 wt.% lanthanum addition and Bi solder with 2 wt.% ...

    • VERIFICATION AND VALIDATION OF NUMERICAL MODEL OF FIRE AND SMOKE DEVELOPMENT IN RAILWAY TUNNEL 

      Autor: Cabová , Kamila; Wald , František
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      The paper describes verification and validation of numerical model of fire and smoke development in a railway tunnel carried out in numerical code Fire Dynamic Simulator. To evaluate a correctness of numerical solution of ...
