A draft amendment selected section of of the watercourse
Vyplel, Adam ; Blahuta, Jaroslav (referee) ; Šlezingr, Miloslav (advisor)
The bachelor thesis focuses on the draft amendment of the selected section of the Veverka watercourse in the cadastral area of Brno-Bystrc in the km 0,632 to 0,918 of watercourse. The adaptation is mainly done as a draft for the stabilization of damaged banks by means of stone retaining wall, wooden pole fencing, stone riprap and gabions. The suitability of the given measures was determined on the basis of the current state of the watercourse. In the chosen section there is a sedimentation reservoir with a boulder chute that has been subjected to an assessment of the stability of the slope surface. Then the HEC-RAS program is used to verify the flow capacity of the whole flow channel for the one-year flow Q1 condition. Subsequently, the vegetation accompaniment and the coastal vegetation of the selected section of the watercourse were designed in order to naturally connect the watercourse to the surrounding forest vegetation.

Monitoring the effect of sample treatment in determining selected properties of biofuel
Štenclová, Kristýna ; Lachman, Jakub (referee) ; Lisá, Hana (advisor)
Diploma thesis is focused on the treatment of biofuel prior to combustion and effect of this treatment on the biofuel characteristics. The first part is a review of literature encompassing characteristics of fuel, preparation of samples, methods of analysis of individual characteristics and a presentation of various types of mills. The second part of thesis is experimental. It is an analysis of sample characteristics under various mill settings with regard to the temperature in the mill during grinding.

The assessment of the capacity of bridge profiles on the Bobrava river
Bezděk, Josef ; Roubcová, Radka (referee) ; Milerski, Rudolf (advisor)
This diploma thesis “The Assessment of the Capacity of Bridge Profiles on the Bobrava River” focuses on making calculations of a system of bridges by using HEC-RAS PC software. This thesis assesses the capacity of bridges and applies knowledge of model research to design increase the capacity. A model of a stream on Bobrava River will be created. Furthermore, modifications of a river bed and bridge profiles will be realized for safe conversion Q100 by these constructions. Subsequently, a model of the modified stream n Bobrava River will be made. Lengthways profiles of water surface, table and graphic outputs from HEC-RAS PC software and modified designs will be output.

Editing roundabout Hviezdoslavova x Bedrichovicka
Klusková, Jana ; Pančík, Vladimír (referee) ; Smělý, Martin (advisor)
The aim of this Bachelor's thesis is solution of the problem of the roundabout that connects road II/430 Hviezdoslavova and the road III/715283 Bedřichovická in city district Brno Slatina. It is about single lane roundabout. The crossroad is situated on the edge of the city and the main problem is satisfactory capacity of it. This problem is linked to the movement of the vehicles leaving the city in the afternoon hours and arriving the city in the morning hours and also with transit transport across the roundabout. The aim is to design new geometry of the roundabout to increase its capacity and also increase the fluidity and efficiency of the passage of vehicles through the intersection with emphasis on the safety of vehicles and pedestrians . The work also includes solutions for pedestrians through the intersection and the draft modifications sidewalks, barrier adaptations of pedestrian crosswalks , points for crossing and adjust the bus stops.

Activation admixtures in concrete
Eger, Lukáš ; Hela, Vlastimil (referee) ; Hela, Rudolf (advisor)
The aim of my bachelor´s work is the summarization and focus on admixure concrete,and the active and inert admixure, which have some positive characteristies for fresh and hardened concrete. Theoretically, I tried to study the increase of their joining potential while this characteristic can be used by either chemici or mechnical way, their combination as well. I also Works on evaluetion of physically mechanical influence for fresh and hardened concrete that can up to 60 days old while the cement was partly substituted by admixure of different character.

Editing a selected section of watercourse
Tomšej, Lukáš ; Olišarová, Lucie (referee) ; Šlezingr, Miloslav (advisor)
This bachelor thesis deals with the modification of the section of the Baťa Canal in the town of Strážnice, namely in the range of 8,300 km to 9,520 km. The alteration is divided into two implementation phases. In the first one, all the sediments will be extracted from the bottom of the canal, which will be subsequently dewatered and plowed into the farmland. The removal of the sediments from the canal bed will be made on the original bottom level stated by the handling and operating rules for the sailing route Otrokovice – Rohatec. In the second implementation phase, adequate bank and accompanying growth will be designed, which are an integral part of stabilization adjustments. Due to historical value of the water canal, a major change in the profile of the canal bed cannot be made. Keeping this in mind, biotechnical stabilization of slopes will be carried out. The aim of the regulation is primarily to increase the capacity of the Baťa Canal for the needs of cruise. Also the planting of new trees will restores vegetation accompaniment.

Adjustments Shearing Procedure Tools
Dziuban, Jiří ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This thesis explains how to determine and eliminate the causes of quality problems in the production of connectors and small electronic components for the automotive industry. The process of making these components is carried out by use of both high speed and low speed metal stamping presses. There are descriptions of the different designs of editing punches, stamping dies, trimming and molding tools and how unplanned issues can occur during the production process. It addresses all the customer requirements for quality end products, listing the type of material, finishes and technology used for the production of individual components as well as their functionality, durability, and economic impacts. All examples of changes in the design or technology of metal stamping presses are based on many years of practical experience and most of them can be successfully applied in other similar type of instrument production.

Catalytic converter and particulate filter functions on diesel vehicles
Šišpera, Adam ; Beran, Martin (referee) ; Bazala, Jiří (advisor)
Tato bakalářská práce se zabývá představením dieselových emisně-redukčních systémů široké veřejnosti, odkrývá základní principy funkce dieselova motoru, mechanismy vzniku emisí a následně se věnuje jejich regulaci za pomocí katalytické redukce a filtru pevných částic. Odhaluje, proč je provozní teplota pro funkčnost těchto systémů klíčová a prezentuje možnosti, jak ji regulovat. V závěru pojednává o možnostech snížení uhlíkové stopy a vyhovění nadcházející emisní normě EURO VII.
