Safe-life extension program for ZLIN Z 126 and 226 airplanes
Jančář, Milan ; Juračka, Jaroslav (referee) ; Augustin, Petr (advisor)
This master's thesis discusses the possibilities of safe-life extension program for ZLIN Z 126 and 226 airplanes, which despite their age and long-end production are still widespread and popular not only in the Czech Republic. The age of these aircraft is also related to the fact, that some aircraft are already approaching its border life, so there is an interest for the longest possible technical and legislative airworthiness. As mentioned in my bachelor's thesis, during the existence of this model series, there was no major damage occurred, except for sporadic exfoliation corrosion of wing flanges. Experience with maintenance of this aircraft points to certain underestimation of the current 5500hrs lifetime and it is obvious to suggest possible steps to increase the current limit. The thesis is therefore considered in this context the possibility of producing new wing flanges made of another material, performed the calculation for wing fatigue exchanged with flanges and designed technological process of this exchange, so that ZLIN Z 126 and 226 airplanes can be safely operated in the future.

Racing cars GT series
Fejfar, Marek ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
This bachelor thesis called „Racing cars GT series“ had taken a task to introduce the reader with a fascinating world of GT class race cars. It deals with history of races, current rules of racing and races themselves, racetracks and their regulations, GT cars and their technical specifications and regulations, which determinates them. Design of engines and underbody components, such as suspension, dampers and anti-roll bars (anti-sway bars) and wheels. Furthermore, the aerodynamic elements, such as spoilers, wings and underbody aerodynamics. And finaly the weight and electronic of cars.

Diversity of cockroach mating behaviour (Blattodea: Blaberidae)
Dvořák, Tomáš ; Kotyková Varadínová, Zuzana (advisor) ; Nedvěd, Oldřich (referee)
Mating behaviour of cockroaches is spectacular phenomenon with three different mating patterns traditionally distinguished. The most common and probably ancestral is type A - female climbing. Then it is type B - male climbing and type C - no climbing. Mating type was described in around 30 Blaberidae species. As it is the only cockroach family where all three types are present, it is an interesting model group for studying evolutionary questions. The main goal of the thesis was detail exploration and description of mating sequences in 21 Blaberidae species, 17 of which haven't been examined in this aspect before. An intrageneric diversity in mating patterns (genus Pycnoscelus) was described for the first time. Moreover, in case of P. tenebrigera, it was not possible to assign its mating pattern to any of the three traditional types. Multidimensional statistical analysis and biological interpretation of qualitative behavioural elements revealed two well separated clusters of mating sequensces. Consequently, we propose to distinguish only two types of mating pattern - ancestral type (identical with type A) and derived type. We also discussed the relationship between wing reduction and occurence of derived mating types. Evaluation of quantitative behavioural elements revealed positive correlation between...

Paranormal romance: an attempt to define the subgenre in the context of young adult literature
Ditrychová, Martina ; Krejčová, Iva (advisor) ; Mocná, Dagmar (referee)
This diploma thesis thematically follows up one of subgenres of young adult popular literature - paranormal romance. Its main aim is to create a comprehensive definition of this subgenre on the basis of interpretation of representative sagas - Twilight by Stephenie Meyer (Twilight, New Moon, Eclipse, Breaking Dawn), Hush, Hush by Becca Fitzpatrick (Hush, Hush, Crescendo, Silence, Finale), Nightshade by Andrea R. Cremer (Nightshade, Wolfsbane, Bloodrose, Snakeroot), Wings by Aprilynne Pike (Wings, Spells, Illusions, Destined) and Anna Dressed in Blood by Kendare Blake (Anna Dressed in Blood, Girl of Nightmares). The thesis was divided into eight chapters. In the first chapter we have outlined the historical development of paranormal romance, in the second part we focused on its genre characteristic. In the third and fourth chapters we tried to create a prototype of heroine and hero of this subgenre. The fifth part is about the steady plot schemes in paranormal romances. In the sixth chapter we have tried to determine a model form of relationship main pair of lovers in the analyzed subgenre. In the seventh part we discussed conflict between everyday reality and the supernatural and the social hierarchy in the fiction world of paranormal romances and we introduced supernatural species and races that...
