Framework for Analysis of Changes in Data Structures of Core Routers
Bednářová, Marie ; Martínek, Tomáš (referee) ; Matoušek, Jiří (advisor)
Páteřní směrovače jsou síťová zařízení, která v kontextu výkonnosti musejí držet krok s požadavky nových internetových služeb a aplikací. Jeden z faktorů, který výkonnost směrovače ovlivňuje, je klasifikační algoritmus, který je součástí procesu přeposílání příchozích paketů na základě jejich cílové IP adresy. Každá adresa je předložena Forwarding Information Base (FIB), která implementuje algoritmus Longest Prefix Matching (LPM) - hledání nejdelšího shodného prefixu. FIB tabulka obsahuje prefixy všech dosažitelných sítí z daného směrovače a na základě poskytnuté IP adresy pak rozhodne, kam daný paket dále přeposlat, aby dorazil na místo určení. Existuje několik LPM algoritmů s různými vlastnostmi, jako je rychlost vyhledávání, náročnost na paměť, náročnost na aktualizaci, a další. FIB tabulka se v průběhu provozu směrovače aktualizuje na základě změn ve Routing Information Base (RIB). Tyto změny jsou prováděny na základě směrovacích informací, které si mezi sebou směrovače vyměňují. Z těchto poznatků vychází téma této práce, které se věnuje tomu jak, dynamické jsou změny datových struktur FIB tabulek v páteřních směrovačích. Tato práce se věnuje návrhu a implementaci frameworku, který je možné použít jako pomocný nástroj pro vyhodnocování LPM algoritmů, na základě toho, jak daný algoritmus mění datové struktury FIB tabulek v páteřních směrovačích. Test je prováděn pomocí simulace, kdy LPM algoritmus je nejprve umístěn do zjednodušeného modelu směrovače jako implementace FIB tabulky. Poté, na základě zpráv protokolu BGP (Border Gateway Protocol), bude algoritmus aktualizovat datovou strukturu FIB tabulky. Celá simulace je monitorována a účinky změn jsou zaznamenávány. Na konci simulace jsou poskytnuty výsledné statistiky. Framework dále umožňuje změnit implementaci LPM algoritmu a také nastavení samotné simulace. Nakonec je funkčnost frameworku prověřena na základě experimentů.

Nástroj pro podporu manuálních GUI testů
Bednářová, Marie ; Smrčka, Aleš (referee) ; Rogalewicz, Adam (advisor)
Manual testing of application is very effective, but at the same time very time consuming process. This thesis will deal with methods and technologies, which would allow computers to not only record and rerun the process without the human assistance or intervention but also make an outcome of this process, which will be in form of report with results of the task run. In the final solution the method of testing was chosen based on the knowledge of application. Within this thesis the design of framework was created with the help of the WinAppDriver technology, which is able to execute the recorded methods as test runs during which the informations about the process itself are being collected. The final report is made, based on the collected information. The outcome of this thesis is a pair of tools, which can automatically execute specifically designed GUI application tests. There were simultaneously included actions, which are necessary to perform before executing the tests. Therefore the program will be able to operate without the need of human assistance.

Danish prepositions. Semantic analysis
Bednářová, Marie ; Štajnerová, Petra (advisor) ; Hartlová, Dagmar (referee)
5 ABSTRACT In this thesis, we examine the possibilities of a semantic analysis of spatial configurations represented by Danish prepositions. In the theoretical part of the thesis, we explore the means that cognitive linguistics uses to describe meaning in general, and to describe spatial configuration in particular. We also briefly present the results of several analyses of English spatial expressions. In the practical part of the thesis, we then apply the cognitive linguistics' terms and methods on material gathered from Danish dictionaries and grammar handbooks and Danish Corpus, in order to achieve an analysis of spatial senses represented by the Danish preposition i. The result of our analysis is a structured overview of the preposition's distinct spatial senses, accompanied by a suggestion of the preposition's semantic network. KEY WORDS: cognitive semantics, spatial scene, schema, spatial configuration, prepositions, Danish

Preparation of instructional materials for cooperative teaching of vocational subject
BEDNÁŘOVÁ, Marie
The aim of this bachelor thesis is the creation of didactic materials on the basis of the implementation of the project in the field of cooperative learning. The goal is to create didactic materials for cooperative learning in vocational subject table setting so they can become part of the school curriculum SOŠZ and Český Krumlov. The work is divided into two parts, theoretical and empirical. The method of system access and content analysis in the study of literature was used for the theoretical part. The method of observation of cooperating groups, methods of induction and deduction was used to elaborate the empirical part of the work. Subsequently, the didactic materials were created based on the used methods. The empirical part also includes an example of lessons in which the newly created didactic materials are used.

The Enter of Concrete Firm at new Foreign Market
BEDNÁŘOVÁ, Marie
Topic of this diploma work was: {\clqq}An entrance of chosen company to the new foreign market``. Principal aim of this work was an evaluation of possibilities and strategies for an entrance on a target market. Partial aim was information processing about a company and target market. Information had to be processed in that way to consider a favoured strategy as the most convenient or if it better to do some strategy modification. Work was drawn up in co-operation with a company Budějovický Budvar, n. p., which is engaged in production of beer. Selected market was China, where this company penetrated at the beginning of the year 2008. The perspective of a target market I surveyed with analysis: Porter{\crq}s model of five powers, STEP analysis and an analysis of attractiveness of a branch. Stability of a company and its opportunity and threats are described by SWOT analysis.
