BIM model – Tomkovo náměstí in Brno
Frýdecký, Filip ; Gottvaldová, Jana (referee) ; Remeš, Josef (advisor)
The subject of this thesis is to show implementation of BIM in linear structures such as roads. In this case there was a normal 2D project, which I must convert to 3D model, using programme Civil 3D. For non-graphical information, standard from SFDI was used at its highest level of documentation that time (PDPS level). After finalizing all graphical and non-graphical information, part of the model was later converted in 5D model, adding cost and schedule. This thesis is supposed to show application of BIM in linear structures such as roads and point out problems from software side such as norms and methodology.

BRIDGE ON D1 (LIETAVSKÁ LÚČKA - VIŠŇOVÉ) OVER VALLEY AT km 4.313
Hudyma, Nazar ; Dvořák, Tomáš (referee) ; Zich, Miloš (advisor)
The subject of this Master's thesis is the design of a road bridge on the D1 in the section Lietavská Lúčka - Višňové in the Žilina Region, Žilina District, Slovak Republic. The bridge is used to cross the valley in KM 4,313 and the road in KM 4,410. Three variants of bridging were proposed, but further in the work an assessment is made on one of the variants. The total length of the superstructure is 354.00 m, the theoretical total span of the structure is 352.00 m. The bridge has 4 spans and is constructed by free cantilever method .The locations of the supports were limited by unsuitable geological conditions at the construction site (active shear area in Quaternary sediments), especially in span No. 3 (span lenght 104.00 m) and span No. 4 (span lenght 75.00 m). The monolithic part of the bridge structure will be concreted by free cantilever method with the largest length of the cantilever 52.00 m. The outermost parts of fields No. 1 and No. 4 will be cast-in-place using fixed scaffolding.

Adjustment an intersection of Přístavní x Obvodová in Brno
Nykodým, Miloš ; Patočka, Miroslav (referee) ; Smělý, Martin (advisor)
The one-lane roundabout is designed at the crossing point of road II. Class (Ob-vodová) and local road (speed-A, Přístaviště) in Brno. The current state is unsatis-factory. The danger is at risk due to the increased maximum permitted speed before the junction and also because of the MHD JMK bus stops, which are cur-rently solved in the form of a lane stop in the local road, or with partial bus bay. The goal of this bachelor thesis is to maximize the safety of traffic participants. Furthermore, emphasis is placed on minimizing interference with existing struc-tures, the environment and aesthetics.

Principals, switching functions and routing techniques in computer networks
Dvořák, Pavel ; Pelka, Tomáš (referee) ; Polívka, Michal (advisor)
This bachelor thesis consider main principles and function of active network components. Mainly is intent to component working on the third level of referential model ISO/OSI, router. There are described its main parts and more closely charactered routing protocols. Then is verified the ability of dynamic routing to react to failure in the network and there is measured the reaction time of crossing to secondary route when using different routing protocols. Another part of the thesis is focused on the questions of Quality of Service (QoS) and its support in computer networks. There are explored various ways of the QoS configuration on the routers and the proper of them is chosen and applied to the test network.

Networking Subsystem Configuration Interface
Lichtner, Ondrej ; Grégr, Matěj (referee) ; Ryšavý, Ondřej (advisor)
Cílem diplomové práce je návrh síťové konfigurační knihovny s důrazem kladeným na přenositelnost mezi operačními systémy na bázi Linuxu a BSD a rozšiřitelnosti podpory knihovny. V druhé kapitole práce zkoumá dostupné konfigurační rozhraní obou operačních systémů. Detailně pak rozebírá vlastnosti rozhraní Netlink socketů, které je primárním konfiguračním rozhraním pro síťové prvky na Linuxu, a systémové volání ioctl, které má na Linuxu menší schopnosti, ale zato je primárně používané na BSD a jiných UNIX systémech. Jsou též zkoumané rozhraní pro konfiguraci rozdílných firewallů. V třetí kapitole je práce zameřená na konkrétní typy síťových zařízení, specifika jejich konfigurace a jejich návaznost na rozhraní jádra popsané v druhé kapitole. V čtvrté kapitole jsou formulovány požadavky na konfigurační knihovnu: jednoduchá rozšiřitelnost, přenositelnost na různé operační systémy, podpora sledování změn a událostí a rozšiřitelnost o různé typy uživatelských rozhraní. Na základě výzkumu z předcházejících dvou kapitol je přednesen návrh knihovny. Návrh definuje konfigurační rozhraní jako hierarchii abstraktních tříd, oddělených od implementace. To umožnuje mít současně několik implementací stejného konfiguračního rozhraní i v rámci jednoho operačního systému. Jako vstupní rozhraní knihovny je definovaná třída LibNCFG, která má na starosti tyto konfigurační objekty vytvořit namísto uživatele. Tímto je dosažená jednoduchá rozšiřitelnost knihovny o nové rozhraní operačních systémů i o podporu konfigurace nových síťových prvků. Podpora pro nové uživatelské rozhraní se dá implementovat jako nová služba, která zabaluje rozhraní knihovny a poskytuje jiná rozhraní. Pro podporu sledování změn poskytuje třída LibNCFG metody pro registraci zpětných volání pro definované události. Ve čtvrté kapitole práce detailně popisuje rozhraní třídy LibNCFG, modulu Common a tříd NetDevice, EthDevice a BondDevice, které definují konfigurační rozhraní příslušných typů síťových zařízení. Pro tyto třídy jsou implementované konkrétní třídy NetlinkNetDevice, NetlinkEthDevice a sysfsBondDevice a popsané jejich implementační detaily. V páté kapitole je popsaná ukázková aplikace, která byla implementovaná pro účely předvedení jednoduchosti použití konfigurační knihovny. Nakonec jsou v závěru shrnuté výsledky práce a je vedena diskuze o možných vylepšeních a o pokračování projektu.

Reconstruction of Track Section with Design of Technological Procedure of Works
Hospodka, Pavel ; Brůha, Bohuslav (referee) ; Svoboda, Richard (advisor)
The aim of the thesis is a reconstruction of a double-track railway Hrušovany nad Jevišovkou – Brno in the section of km 145, 9 – 149, 0. The thesis contains modification of geometric parameters of the railway and reconstruction of the superstructure. A trackspeed should be newly increased up to 100 km/h in this section. Design of a railway crossing and railway stop in village Troubsko according to valid legal enactments is also included in the thesis. Within the reconstruction, a re-conditioning of the current drainage and a design of work technology is drafted.

Frame bridge
Kapsa, Štěpán ; Velešík, Marek (referee) ; Koláček, Jan (advisor)
The work deals with the design of a single-pole frame structure of a road bridge, which is based deeply on piles. Due to the size of the span of 26 m, additionally prestressed cables are designed in the supporting structure. The structure is analyzed by a three-dimensional bar model and assessed for serviceability and load-bearing limit states in the longitudinal and transverse directions. Part of the design is a study of the influence of supporting the computational model and a comparison of the effect of active and resting earth pressure on the structure.

Bridge over a highway
Vaculíková, Klára ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The diploma thesis describes the design of curved, pre-stressed concrete bridge over the highway D1. A variant, that is chosen for detail analysis, is a spine girder construction as a continuous beam with 3 spans. The thesis solves the construction to limit states according to applicable European standards (Eurocodes). There are developed clear and detailed drawings and visualization of the bridge.

Mareček, Tomáš ; Formánek, Ing Martin (referee) ; Koláček, Jan (advisor)
This thesis deals with a design of the bridge for second class highway S7,5 through speedway R2 in Slovakia. From the three proposed versions the version with unicameral structure was chosen for further detailed analysis. The longitudinal direction of the structure is designed as continuous three fields. The lenght of the spans is 23,1 + 33,0 + 23,1 m. Detailed design of the selected version of the structure of prestressed concrete bridge is processed according to limiting conditions, including consideration of the impact of the progressive construction of the bridge. It is elaborated a detailed structural analysis including drawings and visualization.
