Bridge on a ramp
Páteček, Tomáš ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The object of this diploma thesis is the design and review of a bridge on a ramp. The bridge is part of a junction between the expressway R35 and the highway D1. Three case studies were made. The bridge construction is solved as continuous beam with six spans. The resulting design was made of prestressed concrete according to valid standards. The gradual construction was taken into consideration.

Diagnosis selected bridge structure
Novák, Jakub ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
The Diploma thesis deals with the Diagnostics of Reinforced Concrete Bridge in the village of Luhačovice. This thesis also describes the individual Diagnostic methods and instruments used in purpose to make Diagnosis of bridge constructions. The main aim of the Diagnostics is to determine the current state of the Bridge which consists in verification of the actual road structure, determination of the physical and mechanical parameters of the Concrete (strength, depth of carbonation) and in some parts of the bridge structure to determine the type, number and position of the bending or shear reinforcement. Based on the evaluation of the laboratory tests a static calculation of the selected part of the Bridge structure is performed. The final evaluation is the determination of the load and the subsequent design of the necessary and recommended measures for maintaining or improving the functionality of the bridge structure.

Conceptual design of bridge crane 8 tonne
Franc, Šimon ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
This bachelor thesis deals with conceptual scheme of a bridge crane with carrying capacity of 8 tons. Intention of this thesis is to scheme out the main specifications and size of this bridge crane. First of all we design and calculate the main bridge girder. Afterwards we calculate and design the cross bars and the travelling wheels. At last the desigh of an electromotor for powering the movement of the bridge crane takes its place.

NorthEast segment of Hranice town bypass
Kelča, Petr ; Jakl, Tomáš (referee) ; Všetečka, Martin (advisor)
The aim of this diploma thesis is to elaborate a variant of the technical solution of the Northeast bypass road of the city Hranice and its subsequent comparison with other variant prepared by the company Linio Plan, s.r.o. The main task of the bypass road is the operation of the industrial zone, through which is achieved the relocation of a large part of the transit traffic from the city centre. The basic difference of compared variants is their location to the city, the solution developed by Linio Plan, s.r.o. passes through the industrial zone and the other variant passes outside this zone.

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.
