  • Automorphisms of Ordinary Differential Equations 

    Tryhuk, Václav; Chrastinová, Veronika (Hindawi Publishing Corporation, 2014-01-29)
    The paper deals with the local theory of internal symmetries of underdetermined systems of ordinary differential equations in full generality. The symmetries need not preserve the choice of the independent variable, the ...
  • Asymptotic convergence of the solutions of a dynamic equation on discrete time scales 

    Diblík, Josef; Růžičková, Miroslava; Šmarda, Zdeněk; Šutá, Zuzana (Hindawi, 2012-01-03)
    It is proved that, for the asymptotic convergence of all solutions, the existence of an increasing and asymptotically convergent solution is sufficient. Therefore, the main attention is paid to the criteria for the existence ...
  • Experimental Increase in the Efficiency of a Cooling Circuit Using a Desuperheater 

    Formánek, Marian; Horák, Petr; Diblík, Josef; Hirš, Jiří (Budapest University of Technology and Economics, 2016-05-02)
    Waste heat from cooling circuits can be a useful source of energy for other applications, such as domestic hot water heaters. Furthermore, by removing waste heat from the cooling circuit, its effectiveness can theoretically ...
  • Flexure response of thermal loaded concrete specimens by acoustic emission method 

    Pazdera, Luboš; Topolář, Libor; Mikulášek, Karel; Smutný, Jaroslav; Hoduláková, Michaela; Chobola, Zdeněk; Seelmann, Herbert (EDP Sciences – Web of Conferences, 2017-05-24)
    The response to fire of concrete structural members depends on the thermal, mechanical, and deformation properties of concrete. These properties vary significantly with temperature depending on the composition and ...
  • Using acoustic emission methods to monitor cement composites during setting and hardening 

    Topolář, Libor; Pazdera, Luboš; Kucharczyková, Barbara; Smutný, Jaroslav; Mikulášek, Karel (MDPI AG, 2017-04-28)
    Cement-based composites belong among the basic building materials used in civil engineering. Their properties are given not only by their composition but also by their behaviour after mixing as well as by the methods of ...
