EURO 6 Emission Standards
Velešík, Aleš ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
Bachelor´s thesis is focused on the approach the issue of Euro 6 emission standards. There is a general description of the tests, which the manufacturer must undertake and successfully complete to produce cars at this emission level. There is also a description of the harmful substances produced from the exhaust system of a car and an overview of the structural elements to reduce them. In conclusion, the reflection on the issue of emission standards and their constant tightening.

Stage IV Emission Standards for Tractor Engines
Vít, Jakub ; Beran, Martin (referee) ; Dundálek, Radim (advisor)
The aim of this bachelor thesis is to explain the mechanism of injection of carbamide and its installation on a vehicle. The first part of this work deals with the reduction of pollutants in the exhaust gases and with the emissions standards which limit the level of pollutants in the exhaust gases. The second part consists of an overview of tractor brands available at Czech market and their classification based on the type of system they use on their new models to reduce the pollutants in the exhaust gases.

Tractor Engines Intake Systems Overview
Pacovský, Tomáš ; Svída, David (referee) ; Dundálek, Radim (advisor)
The main focus of this work is creation of textual and pictorial documentation of equipments used on nowadays tractor engine intake systems. Firstly author is focused on introduction of individual parts of intake system with their detail function description and pictorial documentation. After that the separate intake systems overview is made via world known tractors such as Case IH, Deutz – Fahr, John Deere, Massey Ferguson and New Holland. Every representative of tractor is introduced with its overview and pictures of the most significant parts concerned with inletting of air into the engine. The entire pictures documentation of intake systems overview is made by camera at the place of tractor’s dealer and when this photo documentation was unsatisfactory, the www pages of dealers was used. This bachelor’s thesis should show the progressive development of intake system’s individual equipments. Eventually this thesis can be used to evolve another research projects.

The Operation Assessment of Filtration Units
Hanušová, Veronika ; Biela, Renata (referee) ; Kučera, Tomáš (advisor)
The first part of this bachelor's thesis deals with knowledge of water works filtration gathered from Czech and foreign literature. Following this information is a group of criterions evaluating the working of filtration units themselves. Water treatment in Hrobice and Kroměříž is assessed in the second part of this thesis.

E-mail server and anti-spam protection
Kučera, Jan ; Luc, Ladislav (advisor) ; Veber, Jaromír (referee)
This thesis deals with e-mail server and anti-spam protection. Its content is the presentation of information on various types of spam, anti-spam protection options and principles of e-mail communication. Furthermore, the content of this work is to install and configure e-mail server and test its anti-spam filters. Test results are compared with the results of the free e-mail inboxes. The main goal is to provide readers with comprehensive information on spam issues, and also helping them when making e-mail server on their own. Testing anti-spam protection should offer insight on the quality of the chosen solutions for e-mail server.

DIGITAL IMAGES PROCESSING IN RADIOGRAPHY
PILAŘ, Martin
This thesis is focused primarily on digital image processing and modern imaging modalities algorithms. An algorithm means a method for solving a problem or an instruction. In image processing an algorithm presents the process from data acquisition to the resulting image displayed on the monitor. Therefore, in the first part of the thesis a brief overview of principles of imaging modalities used in radiodiagnostics is given. Collected data have to be analyzed and modelled in a certain way. These modified data are then digitized and ready for further processing. The main objective of my paper was to explain, especially to radiology assistants, the basic operations and algorithms used in image processing that are commonly used. I also tried to prove that not only by changing scanning parameters, but also by changing any image parameters the test results may be affected. On the other hand the operating personnel may invalidate the examination and thus contribute to an imperfect diagnosis. Other sections of my thesis are focused on primary image processing and basic image operations. This information is followed by post-processing or secondary processing of visual information. An integral part of the image processing algorithm consists of hardware and software important for archiving and information transmission. A certain part of my paper is devoted to future trends in image processing. The whole theoretical part is based on practical experience and the results obtained by either creating a software algorithm or by measurement of a water phantom on CT, where the original hypothesis was defended by applying a filter. The results are supported by a graphic and image documentation.
