Machining of Rotating Components on a Universal Machine
Motl, Martin ; Kolář, Ladislav (referee) ; Kalivoda, Milan (advisor)
This bachelor’s thesis deals with the proposal manufacturing technology of a rotary component on a universal machine. The main point of this work is a full technological preparation of production of the component shape of shaft. In the following paragraph is proposal used machines and tools for production. Below is a technological and economic evaluation of production and finally is a description of production of sample component.

Sinumerik 840D control system for turning of the shaft for JAWA 23
Motl, Martin ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This Master’s thesis deals with the proposal manufacturing technology of a shaft with gears on a CNC machine tool. The first part of the thesis is focused on the concise description selected shaft and its use. In the next part of the thesis are state selected materials, which are suitable used for shafts and gears. After that is create drawing component, suggest technological procedure, tool list and machine list which are suitable used for manufacturing selected shaft. In the final part of the thesis is create a CNC program for manufacturing the shaft on the turning and milling machine. Program is created in software SinuTrain 4.7 for control system Sinumerik 840D. The CNC program is verified by graphics simulation to determine a correct function

Variability of meteorological processes in stratosphere in relation to vertical ozone profile
Motl, Martin ; Kalvová, Jaroslava (advisor) ; Halenka, Tomáš (referee)
There is studied an influence of dynamical processes in atmosphere on the total ozone and its vertical profile in this work. There are described known atmospherical processes with influence on ozone variability and statistical methods used in the work at first. Then is studied connection between ozone and tropopause height. There are also monitored time trends of ozone and tropopauzse height. There are computed modes of variability for the field of the geopotential in pressure levels from 500 to 10 hPa in the next part of the work and there is studied a statistical connection between computed modes and ozone. There is constructed linear regression model from time trend and computed modes. This model describes considerable part of the ozone variability and there are discussed possibilities of use some similar model for prediction of the total ozone in the resume.

Global Economy Outlook - December 2013
Adam, Tomáš ; Babecká, Oxana ; Benecká, Soňa ; Klíma, Jan ; Komárek, Luboš ; Novotný, Filip ; Motl, Martin
Výhledy HDP, inflace, předstihových ukazatelů, úrokových sazeb, měnových kurzů a cen komodit. V rámci rubriky „Zaostřeno na…“ obsahuje zpráva analýzu Financializace komodit a struktura účastníků na trzích komoditních futures. Cílem této analýzy je vyhodnocení hypotézy rostoucího vlivu finančních institucí na komoditní trhy a z toho vyplývajících rizik např. v podobě manipulace s cenami komodit.
