Granular Synthesis in Music Production
Pečinka, Pavel ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
Cílem této práce je navrhnout a vytvořit aplikaci pro granulární syntézu, využitelnou v hudbení produkci. Aplikace je implementována jako VST3 zásuvný modul s využitím frameworku JUCE a programovacího jazyka C++ a je schopná propojení s programy typu Digital Audio workstation, zkráceně DAW, což jsou programy sloužící jako centrální bod pro hudební producenty, kde mohou mimo jiné vytvářet nové zvuky, provádět mixování skladeb a vytvářet zvukové nahrávky. Tento zásuvný modul je navržen jako sampler a je schopen nahrát zvukový soubor obsahující audio data, která dále využívá pro další zpracování a následné přehrávání. Z vyhodnocení uživatelského testování vyplývá, že je tato aplikace použitelná pro hudební produkci jako nástroj pro granulární syntézu.

Influence of carbon dioxide elevated concentration on wheat flour quality
Drahovzalová, Kateřina ; Márová, Ivana (referee) ; Hrstka, Miroslav (advisor)
This thesis studied the influence of elevated carbon dioxide concentration on the properties of ears, grain and flour in two varieties of wheat (Triticum aestivum). The Vánek and Septima varieties were grown in special greenhouses, both in normal atmosphere with carbon dioxide concentration (AC = 385 ?mol?mol-1), and at elevated carbon dioxide concentration (EC = 700 ?mol?mol-1). Quantitative analysis of grain (the content of crude protein, starch, moisture and hardness of grain) was carried out using NIR, gluten content (gluten index) was determined after washing with water and gluten quality was expressed as falling number. Total crude protein content was determined according to Kjeldahl, total amino acids and amino acids content by ion exchange chromatography. Variety Vánek showed significantly larger size of the spikes, more grains and higher grain weight, when it was cultivated in the atmosphere of elevated CO2 concentration. For variety Septima, the size of AC and EC ear variants was comparable, but the ears of corn grown in the EC had a significantly greater number of grains and greater weight. Vánek variety grown in elevated CO2 concentration had lower weight of 100 grains, Septima variety grown in elevated CO2 concentration had greater weight of 100 grains. The varieties Vánek and Septima grown at elevated CO2 concentration showed significantly lower content of crude protein (28.4%) and gluten index (by 34.6%). In comparison with the AC variant, EC also showed lower overall content of crude protein and amino acids.

Recovery and recrystallization of austenitic steel 08Cr18Ni10T
Čech, Jan ; Gregor, Martin (referee) ; Foret, Rudolf (advisor)
This thesis deals with influences of graded deformations, temperatures and holding times on the grains and subgrains size in steel 08Cr18Ni10T. In literary part of the thesis there are described static and dynamic annealing treatments, then also austenitic stainless steels and some selected types of their processing. In experimental part there is studied grain size on differently deformed samples annealed in temperature range 1050–1200 °C for 10, 50 and 100 minutes. Analysis of present structures units was perform by EBSD. Except of that, there were realized chemical analysis of selected inclusions and also hardness test were realised. Achieved measurement shown, that grain size of chosen steel is depended on all 3 variable values.

Project of grain silo
Pilař, Vlastimil ; Malach, František (referee) ; Malášek, Jiří (advisor)
The goal of the Master thesis is to design a grain container. The thesis involves a possible method of grain storage depending on the quality and condition of the grain and also the ways of filling and emptying the container with all the problems that might occur. The thesis deals for example with a possibility of occurrence of vault and with it associated change of state of stress, or with the pressure surges in the container. The thesis involves an analysis of an appropriate construction solution, a design of the main dimensions of the container and a test calculation of the container ´s strength.

Methods to increase the visibility of the original austenite grain boundaries in steels
Gamanov, Štěpán ; Klakurková, Lenka (referee) ; Juliš, Martin (advisor)
This thesis deals with methods of revealing prior austenite grains in steels. The objective was to describe and demonstrate these basic methods on samples. The theoretical part deals with the importance of austenite grain and its size, with description of base methods of revealing austenite grains, and with methods of determination of grain size. The practical part consists of pictures and commentary of samples wich were made with some of the base methods described in the theoretical part. Conclusion consists of comparison of our and external results and also expanding commentary on individual methods.

Compactibility of the materials for subgrade
Kolbábek, Jiří ; Varaus, Michal (referee) ; Stehlík, Dušan (advisor)
This thesis is focused on differences between compaction of fine-grained and coarse-grained soils. It presents selected compaction methods and it describes their principles and implementation procedures. In the practical part is performed classification of both types of soils and then samples are compacted by three methods. The result of this work is to compare the effects of compaction on fine-grained and coarse-grained soil.

Determination of stability of fuel feeding into boiler
Skalický, Michal ; Chýlek, Radomír (referee) ; Lisý, Martin (advisor)
This bachelor thesis deals with the determination of stability of fuel feeding into boiler. The principle of the screw conveyor is described at the beginning of the thesis. It is followed by a description of the individual parts of the worm. The second part of the research deals with the properties of the materials transported. The second half of the bachelor thesis is practical. In this section there are experimentally measured values of flow of sawdust and wood chips. At the end, the measured values are compared and evaluated.

Ohrožení potravinové bezpečnosti vybraných zemí Afriky a Blízkého východu vlivem válečného konfliktu na Ukrajině
Holzerová, Valentýna
The aim of the thesis was to determine the impact of the war conflict in Ukraine on the export of wheat and maize from Ukraine to selected countries in the Middle East and North Africa. Lebanon and Libya were chosen to handle the impact of the said conflict due to their heavy dependence on Ukrainian wheat and maize imports. The literature review focuses on the stability of food access, specifically the impact of war conflicts on food security, including the historical context. The results of the paper include Ukraine's position within world agricultural markets. Total agricultural production and exports of wheat, maize and other crops from Ukraine to selected countries for the period 2010-2020 were investigated. The evolution of wheat and maize exports since the beginning of the war in Ukraine was also tracked. The selected countries were then surveyed on the reasons for their own insufficient agricultural production and why they are so dependent on grain imports. Based on the collected data and food security indicators, the impacts of the war in Ukraine were investigated. For selected countries, the consumption of wheat and maize for both human consumption and feed purposes was surveyed.With the closure of Black Sea ports since the start of the war and the significant reduction in grain exports from Ukraine, both Lebanon and Libya have faced sharp price increases and reduced imports of grain and oilseeds from Ukraine. For both Lebanon and Libya, wheat is a staple agricultural crop that provides a regular source of food. Maize is also a widely imported commodity that is used as livestock feed rather than for human consumption. Lebanon is more vulnerable to reduced wheat imports, while Libya is vulnerable to reduced maize imports.Both countries are highly dependent on cereal imports, and in addition, the countries face a number of challenges that already threaten their food security. The thesis also compares which of the selected countries has been more impacted by the war and why.

Experimental granular software with spatial setting
Pospíšil, Tomáš ; Dlouhý, Dan (referee) ; Indrák, Michal (advisor)
This thesis deals with a design and realization of the experimental software, which has the task to distribute the granular synthesis into surround sound, specifically into the octofonic sound system. The software is designed as a VST3 plugin, which was created in a JUCE framework. Apart of problematics mentioned above the thesis also contains theoretical and technical knowledge linked with granular synthesis, surround sound and a form of realization of a resulting software. The end of this thesis is dedicated to the testing phase and deficits of resulting software.
