      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      The equilibrium shape of a critical nucleus has strong impact on important parameters of nucleation theory, such as nucleation rate. While on the flat substrate the growing nucleus has a shape of a spherical cap, a shape ...
    • AUTOMORPHISMS OF ALGEBRAS AND ORTHOGONAL POLYNOMIALS 

      Autor: Gromada , Daniel; Pošta , Severin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      Suitable automorphisms together with complete classification of representations of some algebras can be used to generate some sets of orthogonal polynomials “at no cost”. This is also the case of nonstandard Klimyk-Gavrilik ...
    • EFFECTIVE USE OF ROTARY FURNACE SHELL HEAT 

      Autor: Lisuch , Julius; Dorcak , Dusan; Spisak , Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      Significant proportion of the total energy expenditure for the heat treatment of raw materials are heat losses through the shell of rotary furnace. Currently, the waste heat is not used in any way and escapes into the ...
