Auction
Mencl, Vojtěch ; Kocanda, Jiří (advisor) ; Bureš, Tomáš (referee)
Trading on the Internet is a modern way of offering products and services. Electronic auction belongs among interesting ways of trading on the Internet. The aim of this work is to analyze, design and implement e-commerce. Inaukce is a web application which convey auction or bazaar sale of various items on the Internet. Users access the application in different roles using web browser. These roles differ in users rights. After being logged on, users with appropriate rights can offer or buy items. In the administrative role, there is a option to manage user accounts and traded items. System monitoring is also available.

Silicified stems of upper Paleozoic plants from the Intra Sudetic and Krkonoše Piedmont basins
Mencl, Václav ; Sakala, Jakub (advisor) ; Pšenička, Josef (referee) ; Florjan, Slawomir (referee)
The late Paleozoic deposits of the Czech Republic are famous for their rich occurence of silicified stems. Despite the fact they have been often described and are well-known among scientists and collectors, their modern evaluation is lacking. This work summarizes results of recent anatomical and paleoenvironmental studies of silicified stems of the Intra Sudetic and Krkonoše Piedmont basins, where are these fossils found very frequently. Based on field research and review of public and private collections, the presence of silicified remnants was proved in several stratigraphic units. Firstly, this work deals with silicified stems of calamitaleans, which are known from the Ploužnice Horizon of the Krkonoše Piedmont Basin, and some gymnosperms. Based on anatomical studies of the secondary xylem and other related features there were found two species of calamitaleans: Arthropitys cf. bistriata and Calamitea striata. Secondly, the more abundant Agathoxylon - type of wood was divided into two groups, which are assigned to cordaitaleans, and conifers. The palaeoenvironmental conditions were partly reconstructed according to sedimentary structures and also according to cordaitaleans - conifers ratio in each wood-bearing layer.

Natural Language Processing of Textual Use Cases
Dražan, Jaroslav ; Mencl, Vladimír (advisor) ; Plátek, Martin (referee)
Use cases written in a natural language are usually employed for specifying of functional requirements. The format of a use case is not standardized but use case sentences traditionally adhere to a simple structure and describe actions which are either communication actions (among actors and a designed system), or internal actions. The natural language is used because it is comprehensible for stakeholders and is universal enough to capture most of the requirements but it is difficult to analyze it in an automated way. Vladimír Mencl employed state-of-the-art linguistic tools to extract a behavior of a system under design from textual use cases. The behavior specification is described in form of pro-cases. His work shows that this is possible but he met several issues. In this thesis, we solve some of the issues. We propose an algorithm based on the Mencl's algorithm which allows to process more use cases than the Mencl's one and we describe a metric which evaluate a quality of parse tree. The metric helps to select the best parse tree of a use case step from parse trees generated by different linguistic parsers. It addresses the issue of eliminating an incorrect parse tree returned by a single parser.
