Effect of conservation grazing on dry grasslands of the Czech Republic
Marek, Matouš ; Münzbergová, Zuzana (advisor) ; Karlík, Petr (referee)
This diploma thesis is focused on grazing management in the Czech Republic, namely in Prague, České středohoří and Český kras. More specifically, on dry semi natural grasslands (Festucion valesiacae, Bromion erecti and Cirsio-Brachypodion pinnati). The main aim of this thesis was to identify the total effect of grazing in all its forms on the species composition and the diversity of vegetation. Data were collected in 2022 on 54 pastures subjected to conservation grazing, where the management has been going on for 1 - 24 years. Data have been collected on individual localities using phytocenological relevés. Data on the management have been obtained through talks with locality administrators and through questionnaires. Used covariates were associated with the micro-site of the phytocenological relevé, climatic data, types of surrounding vegetation, place of the relevé, soil chemical analyses and the management. The results of this thesis show that grazing predictors often influence broad-leaf grasses, especially Bromus erectus and Brachypodium pinnatum, which negatively affect endangered species. Species composition is mainly affected by the time since start of the management, and the season of grazing. Spring and autumn grazing were identified as positive tools of management (increasing numbers of...

Recursive IPC Network Architecture: Analyze and Model of Enrollment
Jeřábek, Kamil ; Marek, Marcel (referee) ; Halfar, Patrik (advisor)
This thesis is focused on analysis of the Enrollment and integration of this phase to model of Recursive InterNetwork Architecture (RINA) that is developed in the OMNeT++ simulation environment. In this thesis is the RINA architecture described generally. Furthermore, there are listed cases of the Enrollment and the Common Application Connection Establishement Phase, and it is described when starts and ends. The thesis is especially focused on design and implemntation of these phases of communication in the OMNeT++ simulation environment within Pristine project.

Modeling and Simulation of Spanning-Tree Protocol
Poláčeková, Simona ; Marek, Marcel (referee) ; Veselý, Vladimír (advisor)
This term project deals with the functionality of Spanning Tree protocols, especially the Rapid Spanning Tree Protocol, and the Multiple Spanning Tree Protocol. The primary usage of spanning tree protocols is the prevention of loops within the data link layer, the prevention of a broadcast storm, and also dealing with redundancy in the network. Moreover, the project contains the description of configuration of these protocols on Cisco devices. The main goal of this thesis is to implement the Multiple Spanning Tree protocol into INET framework within the OMNeT++ simulation system. Then, the implemented solution is tested and it's functionality is compared with the referential behavior in a Cisco network.

Monitoring VoIP Networks
Drozda, Tomáš ; Marek, Marcel (referee) ; Matoušek, Petr (advisor)
This thesis deals with the monitoring VoIP networks. The main objective of this work was to design and then to program monitoring systems for IP telephony network using SIP signaling protocol, primarily for billing purposes. Another important objective was to explore the possibility of obtaining geographic location of the communicating stations. The theoretical part of the thesis deals with the description of the SIP protocol. The rest of the thesis is focused to the design and implementation of the system. The system was implemented as a set of console applications that are complemented by a web application that is used to display the obtained data. Geolocation was solved with the help of IPInfoDb services that provides API for obtaining geolocation information.

Progressive cladding system with corrosion protection function
Marek, Martin ; Taranza,, Luboš (referee) ; Drochytka, Rostislav (advisor)
Corrosion of reinforcement in reinforced concrete is a huge problem. Corrosion of reinforcement has a great effect on the service life of reinforced concrete structures. The subject of this work is to verify the inhibitors properties and their efficiency using physical and electrochemical methods. The aim of this work is the design of formwork panels with corrosion protection. The formwork panels are on different material basis. Corrosion protection is ensured by the use of migration corrosion inhibitors.

Implementation of Delta-t Transport Protocol
Chovanec, Zdeněk ; Marek, Marcel (referee) ; Koutenský, Michal (advisor)
Transportní protokol Delta-t se v současné době vyskytuje pouze ve formě návrhu. Cílem této práce je vytvoření implementace protokolu v prostředí Linuxového TCP/IP zásobníku. Implementace bude mít formu zásuvného modulu. Protokol Delta-t patří mezi protokoly zajišťující obousměrný spolehlivý přenos. Protokol přichází s velmi jednoduchým a efektivním způsobem správy spojení. Spolehlivé sestavení a ukončení spojení není realizováno prostřednictvím handshake zpráv. Aktuální stav spojení je dán pouze dobou, která uběhla od posledního přijetí či odeslání datového segmentu. V ostatních aspektech se Delta-t podobá protokolu TCP, a proto budou jejich implementace vzájemně porovnány.

Progressive types of formwork with anticorrosion protective function
Marek, Martin ; Vaněrek, Jan (referee) ; Drochytka, Rostislav (advisor)
The corrosion of the reinforcement is the main cause of malfunction of the reinforced concrete. It causes meaningful increase of liveness of the construction. The subject of this thesis is development of progressive concrete reinforcement with anticorrosive protective function. Theoretical part is focused on study and description of available corrosion inhibitors, mainly migrating inhibitors. Theory also includes summary of the principles of concrete reinforcement corrosion. The purpose of the thesis is application of migrating corrosion inhibitors to the formwork and basic testing of their efficiency.

The Complex Diagnostics of Reinforced Concrete Construction
Marek, Michal ; Heřmánková,, Věra (referee) ; Anton, Ondřej (advisor)
The aim of this thesis is a complex evaluation of reinforcement in reinforced concrete construction and its comparation with contract documents. In the next step we will calculate static reviews for each part of the construction. In case that some of the parts will fail this review, we will have to project such a solution that the construction wont get damaged from excessive load. In the end we will make an all in all evaluation of the examination and the construction.
