Mobile IPv6 in OPNET Modeler
Žáček, Martin ; Růčka, Lukáš (referee) ; Skořepa, Michal (advisor)
Master’s thesis includes knowledges about mobility support in IPv4 networks and studies abilities for mobility support in IPv6 networks. Describes protocols for mobility support, their functions and topologies like MIPv6 (RFC 3775), FMIPv6 (RFC 5568), HMIPv6 (RFC 5380) and F-HMIPv6. The thesis contains a design of the simulation MIPv6 in the OPNET Modeler program and the measured results are explained. There are analysis of source code for mobility support in MIPv6 too, which were used for design a new protocol according to FMIPv6 in the OPNET. The following parts of the proposal have been successfully resolved. The link-layer events detection, which triggers FMIPv6 protocol and implementation of two new types of messages, RtSolPr and PrRtAdv. Knowledges from this thesis could be used for next development of FMIPv6 in the OPNET. But could be used for generaly development new protocols working at network-layer too.

Experimental MANET network in NS-3 simulator
Vadkerti, Gabriel ; Langhammer, Lukáš (referee) ; Bartl, Milan (advisor)
This thesis deals with the problem of MANET networks. It presents routing protocols, their types, advantages and disadvantages. The protocols, such as AODV and OSPF, are analyzed in detail. The next section describes the NS-3 simulator and the meaning of its key codes. There are named and explained the most common mobility models and their correct writing into the source code. A MANET network simulation is created and a program for indicating the routes of packets through the network is introduced. The next describes traffic models for data networks. A simple traffic model for NS-3 and a program for graphic representation of this traffic were created. The DCE module for NS-3 is introduced in the last section and a demonstrational program of using Linux stack is created.

Mobile Machineries Used for Grinding of Aggregates and Recycled Materials from Building Waste
Hurník, Štěpán ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This bachelor´s thesis is the introduction to the problem of grinding natural materials and recycling building waste by mobile crushing machinery. The first part of work includes a detailed description of crushers themselves and differences between them. Next basic machine development is dealt with, as well as questions evoked by this topic. These questions are concerned with the mobility and problems of recycling. Further, there are current market offers for the preformance given. It deals with the parameters of the individual machines, on which their mutual comparison is given and displayed in graphs. The final part of the thesis consists of the general evaluation of machines for the above-mentioned purposes from different points of view: comparsion, market supply and a careful view into the possible future progress.

Study on the Mobility of Selected Representatives of Pharmaceuticals in Natural Systems
Bednárová, Paula ; Pořízka, Jaromír (referee) ; Kalina, Michal (advisor)
This diploma thesis focuses on interactions of chosen pharmaceuticals with soil and study their mobility. First part is devoted to the characteristics of the most common pharmaceuticals that appear in the environment, specifically antibacterial chemoterapeutics and analgetics. Subsequently, the occurrence of the pharmaceuticals in environment, their sources and effects are described. Further, the work focuses on soil components and soil organic matter. In conclusion of the theoretical part is the description of used analytical method for processing of the results and also the current state of the problematics. In the practical part of the thesis the experiments were made and analyzed and further served for better understanding of adsorption and interactions of chosen pharmaceuticals with soil and humin acids as the main reactive part of the soil.

Chromium and chromium species cycle in environment
Nevrlá, Jana ; Sommer, Lumír (referee) ; Dočekalová, Hana (advisor)
This work focuses in the first theoretical part mainly on the possibility of entering various forms of chromium into the environment, their accumulation and transformation in environmental compartments. There are also described methods of sampling for analytical determination of chromium, the type of treatment of these samples and the most analytical methodologies for the determination of chromium in the oxidation stage III and VI. The experimental part is focused on the quantitative determination of Cr(III) and Cr(VI) in waste water, taken from the neutralizatoin station of the Chemical faculty of Brno University of Technology, by using selected spectrophotometric methods and the obtained results are compared with the results of analytical determination of total chromium by atomic absorption spectrometry.

Network mobility in Mobile IP
Havelka, Michal ; Novotný, Vít (referee) ; Skořepa, Michal (advisor)
his semestral thesis is focused on issue network mobility (NEMO) beeing extension of protocols Mobile IPv4 and Mobile IPv6. It describes basic principle function of protocols Mobile IP, defines differences between mobility of nodes and mobility of network and suggest various situations, which may occur in combination these two protocols. Further, it describes differences between basic protocol network mobility (RFC 3936) for IPv6 and it’s extension (RFC 5177) for IPv4. Practical part of work consist in simulation network mobility in application OPNET Modeler and discussion of results, which has been discovered on the base of this simulation.

Railway (flexible space)
Smržová, Kristýna ; Štěpán, Marek (referee) ; Mléčka, Jan (advisor)
Finding new use for the existing railway tracks, which prove themselves as one of the best ways to carry heavy or sizable load. Therefore they have an ability to carry a space. Verification of merging railway with everyday life. Design of a modular units and modifiable structures. Utilization of modern technologies. Demonstration of a proposal of a design using typical examples of railway structure and its surroundings. Taking advantage of railway tracks, unused train stations, neighboring unused industry grounds etc. Description: New possibilities of using railway tracks and surrounded unused sites. Design of modular structures adapted according to selected areas. Utilization of modern technologies.
