Methods of Static Buckling Analysis
Svoboda, Filip ; Eliáš, Jan (referee) ; Frantík, Petr (advisor)
The aim of this theses is to create application, which is able to calculate buckling load of structure made from 1D bar elements, using finite element method. introduction is devoted to basic principles of buckling and derivation of necessary formulas. Then are described all operations and numerical methods needed for the application. At the and is in detail analyzed few structures and results are compared with known solutions or with other applications.

Assembled structure of hall
Bartosch, Václav ; Chalivopulos, Paris (referee) ; Zich, Miloš (advisor)
Master´s thesis describes the design and static calculating of selected elements of prefabricated reinforced concrete hall with bulit-in office, elaboration of basic drawings of the project documentation, shape and reinforcemenet drawings of these selected structural prefabricated elements. The work also includes technical report, details of selected element´s contacts, drawing of plates and study of the behavior of reinforced buildings. Calculation was performed by using a computer program AxisVm, Microsoft Excel a IDEA StatiCa

Wavy Films Flow: Linear Stability and Evolution
Wein, Ondřej ; Tihon, Jaroslav
The Orr-Sommerfeld (OS)problem is analyzed in terms of the relation between complex-valued wavenumber alfa and celerity c. For the long-wave regular branch, Taylor series to c(alfa) is found to be of limited use, as its convergence radius pi is to small. Wave characteristics of the conception region, including besides c(alfa) also the wall shear rate impendance q , are obtained for the maximum spatial growth rate scenarioo by solving the OS problem numerically.
