    Jazykové vzdělávání studentů na FS TUL
    (Technická Univerzita v Liberci, 2013-01-01) Petera, Pavel; Kiryková, Simona
    Tato práce se snaží vyjmenovat promenné jazykového vzdelávání od MŠ až po VŠ a jako cíl je pak zanalyzovat, zda výuka jazyku studentu FS TUL je dostatecná, prípadne jaké kroky by mohl student sám, nebo vedení fakulty podniknout, ci prípadne i systémové kroky, které by umožnily, aby fakultu opoušteli lépe jazykove vybavení absolventi.

    Studie vlastností biopolymeru HL 103 v souvislosti s fyzikálním stárnutím
    (Technická Univerzita v Liberci, 2008-01-01) Petera, Pavel; Běhálek, Luboš
    In this tesis is mentioned charakteristics and posibilities of use biopolymers in praxis and comparation with conventional polyethylen. On the base of experimental measuring of the biopolymer PSM HL 103 and conventional polyethylen Liten BB 29 was formed ralations of their properties on time.

    Vliv parametrů předtvarování fólie na kvalitu tvarově složitých dílů u technologie IMD
    (Technická Univerzita v Liberci, 2016-01-01) Petera, Pavel
    Presented dissertation is aimed on new technology IMD with pre-forming (transfer type), which allows highly productive decoration of injection-molded part directly in injection mold. IMD with pre-forming is an alternative to commonly used IML but when compared together IMD with pre-forming has a clear advantage in strong cost reduction according to IML. Additionally complexity of feasible shape is much higher in the case of IMD with pre-forming compared to standard IMD. This thesis is focused on evaluation of pre-forming parameters influence on foil deformation during IMD process but as well parts quality characterised by fault presence. Experiment has been done on large and complex IMD part by using hi gloss IMD foil and PC/ABS resin. For the purpose of deformation study was developed and verified new process which included a new way of geometric pattern printing on IMD foil which allowed to evaluate also deformation which happened by melt flow during injection molding process. For evaluation the influence of pre-forming parameters on parts quality was presented own approach of faults presence evaluation. The topic has been solved under the terms of solution of research program SGS 21122.
