Distribution of aerosol particles from ship diesel engines
Šmok, Dominik ; Hovorka, Jan (advisor) ; Vojtíšek, Michal (referee)
3 Abstract Measurements of aerosol particle size distributions in the range 5 nm - 4 µm at 1.5 m above sea level were carried out on board a boat in German waters of the Baltic Sea. The measurements were aimed at characterizing aerosol particles from marine aerosol and from ship diesel engines and their dynamics, i.e. the aging of the exhaust plume in the marine boundary layer. The marine aerosol of PNC5-340 1335-1939 cm-3 is characterized by Aitken, accumulation and coarse modes of CMD 20 and 41-55 nm and 123-159 nm and 1.6 µm, respectively. The ratio of the accumulation to the Aitken mode increases with increasing shipping density. Aerosol particles from diesel engines in exhaust plumes with an age of 2 - 60 s and at a distance of 150 - 600 m from the surveyed ships are characterized by PNC5-340 1-4 -105 cm-3 and CMD 20 nm. The modal size distribution of supermicron particles of Da 1 - 4 µm does not change in the exhaust plume, the total mass of supermicron particles increases only by 1 - 6% compared to the background. The dynamics of the size distributions of aerosol particle numbers is mainly due to the formation, i.e. expansion and dilution, of the plume. However, in the exhaust plume with an age of 6 - 16 s and at a distance of 50 - 150 m, a faster decrease was observed for PNC20 due to the...

Game Portal in Cloud
Pečínka, Zdeněk ; Otrusina, Lubomír (referee) ; Škoda, Petr (advisor)
This thesis deals with the development of the gaming portal in Cloud designed for selected PaaS provider. Informs about the possibilities offered by cloud computing. Summarizes the advantages and disadvantages of PaaS providers. It pursues the design and the implementation of the application, focusing on its scalability and modularity. The result is the gaming portal providing games Tanks and Ships, which you can play against other users or against a computer controlled opponent. The solution contains the evaluation of the scalability of the critical components, based on the results of the stress tests.
