On the Nothernmost and Southernmost Limits of European Land Snail Spatial Ranges
Křepelová, Lucie ; Juřičková, Lucie (advisor) ; Horsák, Michal (referee)
The aim of this work was to evaluate the limits of ranges of European land snail species along the north-south gradient. To work out the document it was necessary to prepare the set of digitalized maps, that enabled to create the database of ranges of the individual land snails species. Based on obtained data I tried to identify places where the northern and southern borders of species ranges are the most frequent. The landsnails' ranges are affected not only by particular life requirements of the individual species (potential limits), but also by other conditions, especially climatic, geographical and historical (truncated limits). In this work I focused on their differentiation. Above mentioned process also enabled me to track the north- south changes in species richness of the landsnails taking into consideration the truncated and potential limits. The most important natural barriers constraining that numerous of species cannot naturally widespread from the south to the north are the Scandinavian Mountains, the Alpes and the Carpathians and suprisingly also southern borders of german and polish lowlands. On the other hand, spreading of the species form the north to the south is limited only by the Alpes. I also tried to distinguish the group of species whose ranges are not influenced by these...

Testing of ZigBee wireless modems
Kasper, Robin ; Molnár, Karol (referee) ; Martinásek, Zdeněk (advisor)
This thesis deals with the testing of wireless radio modems CDX800. Modems communicate in the unlicensed 869MHz band and are based on the ZigBee standard. The first chapter is devoted to the description of this standard. Thesis aims to test the modems according to RFC2544 and RFC1242 recommendations for testing networks, which are discussed in the work. For testing of the network in accordance with those recommendations have been selected hardware testers Trend Unipro GbE. Testers are primarily intended for Ethernet networks, and therefore it was necessary to use converters from Ethernet to serial line which modems use to communicate with other devices. Measurements of the testers were unsuccessful by virtue of inappropriate choice of converters. The work shows potential substitute for these converters. Furthermore, the work deals with testing the modems in terms of radio range on the line of sight and in build-up area. For this purpose was chosen service program Radwin. At the conclusion of the work was created network design for decentralized wastewater treatment for the community Podbřezí from the measured parameters. Designed network is composed of 50 stations and one control center.

Monitoring of hazardous environment
Bilík, Martin ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
Diploma thesis Monitoring of hazardous environment deals with possibilities of construction of monitoring device for the nuclear power station Temelín. In the first part are accurate requirements for monitoring device, individual risks and identify obstacles and opportunities how to overcome them. There is also description of basic options for measuring temperature and environmental monitoring. Using multi-criteria analysis was done the selection of all components, from which is possibility to construct the first development release of monitoring device. 3D models for each component and the overall design visualization facilities were created in the programming environment of Autodesk Inventor. The conclusion provides an overview of the financial cost of the equipment is assembled

Optimization of production process
Nováková, Veronika ; Krásová, Anna (referee) ; Fiala, Alois (advisor)
The aims of this dissertation are to analyze the current state of process control, to identify the product range in selected organization and to design the process planning methodology to ensure an optimal implementation. Optimization is understood as costs minimization while keeping an acceptable continuity of supply. The dissertation contains a description of technological and non-manufacturing processes of brick products, as well as the summary and description of the basic tools of quality management.

Simulation of finding a computer position in Internet
Vrzal, Tomáš ; Jeřábek, Jan (referee) ; Komosný, Dan (advisor)
This bachelor’s thesis puts mind to problematic transmission multimedia data via RTP/RTCP protocol with hierarchical aggregation. In next parts of thesis are explaining design principle and use this transmission via tree structure. In last part is description application in which the simulation ambient uses tree structure. For best results of simulation is use algorithm called “binning”. Application has graphic interface, so that easy manipulation with it. In insertion are pictures and application code.

Analysis of the range of car insurance
Sobotová, Sára ; Vávra, Oldřich (advisor) ; Prokš, Pavel (referee)
The work consist of two main parts. First of all I created a theoretical bassis for the issue of car insurance, then I focus on marketing in the insurance industry and examine its specifics, which I apply to Allianz insurance company because I analyse its product in the practical part of this work. I introduce Allianz on the market at the beginning of the practical part. I also examine factors, which influence the choice of insurer and insurance product. I compare the previous and the new product of Allianz and specify the most important differences in comparison with the competition. The work should provide the reader comprehensible look at car insurance in the Czech Republic. This work is focused on the area of car insurance from the perspective of marketing and focuses primarily on individual insurance.
