Cloud Processing of Atmospheric Aerosol Spectra.
Zíková, Naděžda ; Pokorná, Petra ; Pešice, Petr ; Sedlák, Pavel ; Ždímal, Vladimír
Atmospheric aerosol (AA), and its influence on the cloud formation, lifetime and other properties, remains the most uncertain (with low confidence level) element in the IPCC radiative forcing estimations (Stocker et al., 2013). The AA, however, is influenced by the cloud processing as well (Collett et al., 2008., Zíková and Ždímal, 2016). Cloud processing of AA (and vice versa) can be described on fogs, or on low clouds present at a suitable station. An example of such a station is Milešovka, where fog is present for almost 55 % of the time (Fišák et al., 2009), giving a great opportunity to explore the changes in the particle size distributions due to the cloud processing.

Graphics Intro 64kB Using OpenGL
Menšík, Jakub ; Milet, Tomáš (referee) ; Matýšek, Michal (advisor)
This Bachelor's thesis deals with the creation of a graphics intro with the executable file size limited to 64kB. The graphics intro is created using the OpenGL API and related libraries. The thesis describes many techniques for a graphics content generation including procedural generation, Perlin noise, mipmaps, volumetric light, face culling, instancing, fog, skybox, and techniques used for reduction of a size of the executable files. The result is a graphical intro showing a night city.

RGB MATRIX LED system
Sikora, Roman ; Fedra,, Zbyněk (referee) ; Hudcová, Lucie (advisor)
The bachelor thesis deals with the development of a control software for the rear RGB LED lamp, which allows to design and display any color schemes. The first part of the work aims at development of complete Raspberry Pi 3 control software. Next thing which the thesis deals with is design of user interface for Windows platform for easy creation of color schemes which includes typical functions for a rear lamps like a tial, stop, reverse, fog, direction indicator, coming home and leaving home. Next part of the work is implementation of the control for the model via CAN bus which is used in automotive technology, and to develop the control software for Windows platform. In the project the whole model with Raspberry Pi is tested for Conducted emissions.

Graphics Intro 64kB Using OpenGL
Minařík, Antonín ; Matýšek, Michal (referee) ; Herout, Adam (advisor)
This thesis deals with creating a graphics intro, which's size has to be below 64~kB. Described and used techniques includes: Phong reflection model, fog, skybox, generating textures from noise and shadow mapping. Intro is placed in a city and techniques of generating elements of the city are described. In addition, there are described methods for reducing file size and system for camera animation.

Frequency and composition of fog in the Czech Republic
Esterlová, Jana ; Hůnová, Iva (advisor) ; Stráník, Vojtěch (referee)
This thesis deals with the occurrence of fog in The Czech Republic and its composition. It engages in current status and also historical evolution (since about the second half of 20th century). The thesis is divided into two parts. The first part is the research of the professional literature, which sums up the results of realized studies, explains terms connected with fog and describes methods used for fog quantification. The second part contains results of my own study for the city station Prague-Libuš (1971-2015) and mountain station Churáňov (Šumava, 1961- 2015). The fog is an often underestimated phenomenon, which has provable influence on water balance and contributes to the atmospheric deposition, especially in mountain ranges, where the occurrence is higher. The composition of fog is being changed during the observed time. The amplest ions are in most cases NO3 - , NH4 + , SO4 2- , Cl- a Ca2+ . In connection with decreasing general air pollution shows, it goes also to reduction the concentrations of pollutants in the fog. Because of the lower content of these particles the occurrence of fog might be also lower in the cities and former highly-polluted regions caused by the lower number of condensation nuclei, which is noticeable on Prague-Libuš. In connection with global warming there are...

Fog as a factor contributing to the total atmospheric deposition
Samcová, Anna ; Hůnová, Iva (advisor) ; Stráník, Vojtěch (referee)
This paper is a research of scientific literature. Its objective is to evaluate the impact of fog on the total amount of substances entering ecosystems through the atmospheric deposition process. It summarizes the division of different kinds of fog, its occurrence and basic information about its chemistry. Atmospheric deposition is a process in which substances are transported from the atmosphere to Earth's surface. There is a wet deposition type as well as a dry one. The wet atmospheric deposition is then divided into vertical and horizontal. The influence of the wet atmospheric deposition depends on the altitude. From the elevation of 800 meters above the sea level there is a significant increase in the horizontal component of the atmospheric deposition (e.g. a fog). There are several different kinds of fog that are divided according to diverse criteria. For example depending of their origin, the inside visibility or their duration. Fog is commonly found in places with large humidity. In the Czech Republic region the ion contribution of fog to atmospheric definition is quite underrated. Most common ions in the fog deposition are SO4 2- , NO3 - and NH4 + . These easily become a condensation core for droplets. Atmospheric deposition in total is calculated as the sum of wet and dry vertical...

Visibility at the Praha Ruzyne airport
Kusáková, Kateřina ; Žák, Michal (advisor) ; Pišoft, Petr (referee)
The goal of this bachelor thesis is to show the importance of visibility in flight operations. There are settled minima of visibility for each process, which must be achieved. Visibility has its own daily range, which is closely connected with solar radiation. Its also connected with a vertical structure of atmosphere, direction and speed of wind and current weather conditions. Visibility achieves its lowest values during intensive precipitations and in a fog. Mainly because of an appearance and lasting of a fog, there are compilations at the airport and very often a special procedures must be taken for an organization of flight operations. An appearance and lasting of a fog has a big influence on flight operations and that is why I pay an attention to this in my work. I concentrated myself not only on the daily range of visibility and its dependency on the direction of a wind, but on conditions of appearance and ending the fog as well.

Duration of faling precipitations, fog and mist as factor influencing the timing of vacances
Kothan, Filip ; Sládek, Ivan (advisor) ; Lhotka, Ondřej (referee)
The aim of this paper is to determine suitable term of summer holidays. It should be as long as current holidays in Czech republic, it means 62 days. The paper builds on the bachelor's thesis titled "Optimal timing of summer vacances with regard to climate". The convenient term has been evaluated on basis of characteristics of air temperature, duration of sunshine and the length of day there in the bachelor's thesis. This paper contains the analysis of duration of rain, showers, drizzle, fog and mist. Thus, several terms have been found in both papers. But these are suitable with regard to only one meteorological element or phenomenon. The summer holidays should undoubtedly provide days with the best possible values of more meteorological elements. So the final term was calculated as mean and weighted mean of several dates of the beginning of holidays with the highest values of daily average air temperature, length of day and with the shortest total duration of the complex of rain, showers and drizzle and the complex of fog and mist. The weights of individual elements have been determined in two ways, so we have obtained three terms of holidays: two as result of the weighted mean and one as result of the mean. The best periods for holidays, determined by the weighted mean, are 11th June - 11th...

Integration of the IBM SoftLayer into the ManageIQ Framework
Coufal, Tomáš ; Fiedor, Tomáš (referee) ; Rogalewicz, Adam (advisor)
As cloud computing gains its popularity the complexity of offered services is growing. There exist various different solutions and to manage them effectively is the task for cloud managers. One of them is a project named {ManageIQ}. This thesis aims to describe how to integrate a new provider into this software, what are the required bindings and how to work with the API of the provider. This thesis describes such a process on an IBM SoftLayer provider example. The achieved result enables the user to manage his SoftLayer devices via ManageIQ with ease and also provides him the functionality to provision new appliances.
