Gasoline Direct Injection
Smejkal, Jan ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor thesis deals with the problematics of gasoline direct injection in combustion engines. There is a view of the history of the development of gasoline direct injection in the introduction. The main part focuses on the principle of the process function, description of components of fuel system and specific components of exhaust system. There is also a description of benefits of using gasoline direct injection, especially considering the amount of pollutants in exhaust gas. The following part of the work contains an overview of gasoline direct injection engines and their comparison in terms of power. In the conclusion, there is a consideration of gasoline direct injection development in the future.

Study Of Effect Of Organic Additives On The Morfology Of Zinc Deposit
Smejkal, Jan
Article studies effect of the selected organic additives on zinc deposit properties in relation to negative electrode for Ni-Zn battery. All additives were examined with emphasis on the study of dendritic and mossy structure growth suppression. Additives have been selected in order to their already known benefits for Ni-Zn cell and in order to their using in galvanic production. Additives were examined by XRD diffractometer Rigaku Miniflex 600 HR and electron microscope Tescan Vega 3 XMU.

Organic Additives Controlling Zinc Deposition From Alkaline Solutions
Smejkal, Jan
This work is focused on the study of the effect of selected additives on zinc deposition in alkaline electrolyte for the purpose of using the additives in zinc based battery. Deposition was performed on tinplate in 6 mol/dm3 KOH solution saturated by ZnO and with the addition of organic additives (Slovasol 2520/2, Tween 20, CTAB and Lugalvan G35). All selected additives were examined with the focus on the morphology of zinc deposit and with respect to their ability of dendritic growth suppression. Zinc morphology was studied using an electron microscope and an Xray diffractometer.

Effect of Organic Additives on Electrochemical Processes Influencing Zn-Air Battery parameters
Smejkal, Jan ; Čech, Ondřej (referee) ; Chladil, Ladislav (advisor)
The diploma thesis is focused on the study of the influence of selected organic additives on the properties and morphology of zinc deposit on the negative electrode when used in zinc-air accumulators. Organic additives have been selected based on the study of literature and previously done experiments. The deposition was made on the tin plate electrodes in a solution of 6 mol/l KOH saturated with ZnO with added additives. All chosen additives were studied with a focus on the morphology of zinc deposit and with regard to their ability to suppress dendritic growth. Zinc morphology was studied by using a Tescan Vega 3 electron microscope and a Rigaku MiniFlex HR 600 X-ray diffractometer.

Nevyvinuté půdy suťových polí Vysokých Tater: množství, chemismus a ekologický význam
ŠMEJKAL, Jan
Bachelor's thesis deals with soils of scree slopes in alpine ecosystems of Tatra mountains. It focuses on processes of rock weathering and soil development which lead to release of phosphorus and other nutrients. This thesis contains a proposal of research project focused on quantity and chemical regime of scree slope soils in Ľadové lake catchment with special interest in seasonal dynamics of phosphorus and other nutrients.

Academic Square - Faculty of Fine Arts
Smejkal, Jan ; Kyselka,, Mojmír (referee) ; Nový, Alois (advisor)
The theme of the thesis is a study of the project of the Faculty of Fine Arts in Brno. The site lies on boundary of two city parts, Brno – Střed and Brno – Žabovřesky and it is surrounded by streets Veveří, Šumavská and Bulínova.The project ties together with architectural study from subject TG02, which concerns the Faculty of Forensic Engineering. The final result of both parts is the project of both schools with common facilities. The part of the project is an underground garage where is a space for public parking which is demanded by city hall. The main idea was to create building with respect to surroundings and define itself to the street lines and create the small square inside the block of the buildings. The results are two six-floor buildings connected by two-floor object with atrium.
