Nautiloidea of Upper Cretaceous epicontinental seas in Europe
Frank, Jiří ; Košťák, Martin (advisor) ; Turek, Vojtěch (referee) ; Schlögl, Ján (referee)
The post-Triassic Nautiloidea are not as popular theme within fossils cephalopods research as for example ammonites. They are not very abundant in the fossil records except some rare localities and areas, their morphology is quite conservative and due to the usually poor preservation, their determination and assigning to the species even to genera level is often complicated. Exceptional are taxa with very specific morphology and short stratigraphic and endemic occurrence, which are even suitable for biostratigraphic interpretations. Problematic is also the often poor taxonomical representation of the type material and revision of many taxa is needed. Still nautilids are often represented by reasonable amount in the paleontological collections of natural history museums due to the long history of fossils collecting. Also the scientific literature has been dedicating at least some space to this group since 19 century. The aim of this study is to create an overview about the post- Triassic, especially Upper Cretaceous nautiolidea in the European region of epicontinental seas and prepare a good basement for extensive study of this group. Due to this aim the study is primarily focused on determination of morphological features and also problematic with their interpretation according to the variable...

Oyster bioherms in the Bohemian Cretaceous Basin
Rantuch, Jakub ; Košťák, Martin (advisor) ; Frank, Jiří (referee)
Frustration from shape and size variability of oyster's species Rhynchostreon suborbiculatum (Lamarck) is long known phenomenon. In current state of his systematic it is not possible to consider it fully satisfying. Is it is shown in study of genus Gryphaea by Jones and Gould (1999), that application of modern analytical methods, undoubtly lightens long-darkned places of evolution process. Idea of Videt and Neraudeau (2003), that shape variability of Rhynchostreon suborbiculatum (Lamarck) probably also mirrors heterochronic processes, introduces inspirative and good foundation for future research in this field. Occurence of this oyster is proved from huge range of sites in Bohemian Cretaceous Basin area. It is combination of rich occurance, unique preservation and variability of lithological settings, which gives us unique starting point for next step to solve significant problem. Based on population analyses consisting of biometrical studies supported by oxygen isotope analyses, in future, it will be possible to reach sufficient conclusions of this issue, and progress in our knowledge.

Foraminifera of the Bohemian Cretaceous Basin
Hašková, Barbora ; Frank, Jiří (referee) ; Holcová, Katarína (advisor)
The thesis deals in the compilation part with systematic classification, biology, morphology of the test, ecology and palaeoecology of the Foraminifera. Next research focuses on the history of Cretaceous Foraminifera in our area and the geology of the Bohemian Cretaceous Basin, focusing on Úpohlavy site in the northwestern part of the Bohemian Cretaceous Basin. Three samples from Úpohlavy section were preliminary micropaleontologically analysed. Plankton / bentos ratio was counted. Genus Heterohelix and Planoheterohelix was described and taxonomically studied. Keywords: Upper Cretaceous, Bohemian Cretaceous Basin, Foraminifera, Heterohelix 1

Comparison of rapid development frameworks Nette(PHP) and Grails(Groovy)
Frank, Jiří ; Pavlíčková, Jarmila (advisor) ; Oraný, Vladimír (referee)
This thesis aims on comparison of rapid development frameworks Nette and Grails. Main objective of this paper is achieved by brief description of both languages (PHP, Groovy) and frameworks. Next is defined relatively complex set of criteria for comparison itself. Frameworks are then compared based on this set. Last part is development of the identical application on both platforms, thanks to which the practicle comparison may be done. The main contribution of this work is in comprehensive comparison of platforms Nette (PHP) and Grails (Groovy), which may be used for making decision about which platform to take for a development of new application. Comparision of course may serve like an information about that what developer should keep an eye on, what can make life easier or harder especially in contrast with that what offers concurent platform.

Audit of electronic shop websites
Frank, Jiří ; Molnár, Zdeněk (advisor) ; Brdek, Vladimír (referee)
This paper describes the basic methodology of the auditing of web sites and general principles that should be followed by each site. Methodologies focus on the evaluation of technical requirements and graphic design, as well as analysis of the aspects of SEO, traffic and performance. This proposed set of evaluation techniques is then practically applied in the audit of one particular online store and its main competitors. Conclusions and recommendations are drawn from the analysis and these are discussed in the final chapter. These recommendations should help improve the current state of trade. The main contribution of this work is in defining a comprehensive set of essential methodologies that can be effectively applied in practice.
