Dolní Nechory u Prušánek - rozšíření provozu vinného sklepa
Růžička, Matyáš
This thesis is focused on reconstruction and superstructure on wine cellar in Dolní Nechory. Owner of the wine cellar demanded the reconstruction in order to build recreation facilities. The important fact is, that underground arch and brick part will be retained. Superstructure with wooden frame construction will be designed above the brick part. Second considerable fact is building the superstructure in style that would not disturb with its view current architectural style of the winery village. The construction will be designed above the arch part so that it will not burden it and it will arise a freestanding structure. The thesis includes analyses of several versions, each version avails the space in a different way. First two versions utilize area of the current building and land. In the following versions is analysed possibility of buying of the neighboring land and realizing the reconstruction with using of the space. In the conclusion each version is reviewed by its practicability and utilization.

Hodnocení a výběr perspektivních genotypů meruněk ze šlechtitelského programu Ústavu Ovocnictví
Růžička, Matěj
This diploma thesis is focused on the evaluation of selected phenological and pomological features of apricots. It is also focused on laboratory analysis, where was measured titrable acidity, vitamin C (ascorbic acid), phenolic substances, flavonoids and antioxidant kapacity. It was determinated in the skin, pulp, but also in the MIX, which was composed of 20 % of skin and 80 % of pulp. The experiment took place in 2020 on the side of the Faculty of Horticulture, Mendel´s University in Brno, at the department of Fruit growing in Lednice. The experiment worked with hybrids LE-6016, LE-5500, H.873, LE-5959, LE-8555, H.997/134, LE-7222, LE-1102/52, H.1116/0/2020, H.848, H.871, H.987/490, LE-9900, H.987, H.1102/91, H.1077/poslední, H.994, LE 11866, LE-11909, H.970/135 and Pozdně kvetoucí. For comparasion with hybrids, was used the variety ´Velkopavlovická´, which was evaluated in the same year. The features were evaluated according to the descriptor for the species of Prunus Armeniaca L. The theoretical part includes the origin and expansion of apricots, botanical characteristics, morphological traits, cultivation requirements, breeding goals, breeding in the Czech Republic and abroad, variety assortment, new generation varieties, nutritional values and their inpact on human health. The results were appropriately processed into graphs and tables.

Icing on radiator used for heat pump for EV vehicles
Ostroukhov, Andrei ; Růžička, Marek (referee) ; Bazala, Jiří (advisor)
Tato práce je zaměřena na vliv kondenzace na přenos tepla chladičem elektromobilů. Teoretická část popisuje princip systému tepelného čerpadla a obsahuje také popis přenosu tepla v radiátoru a kondenzace na jeho povrchu. Práce popisuje řešení pro snížení množství kondenzátu, byly demonstrovány různé metody. Byl také popsán proces vzniku námrazy, tvorby ledu na povrchu výměníku tepla a také byli popsané mechanická poškození způsobené námrazou. V praktické části bude použit simulační software pro porovnání množství kondenzátu, který se objeví na povrchu výměníku tepla při použití některých níže popsaných metod. Simulace také určí závislost tepelného toku na množství kondenzátu.

Numerical Modelling of Fatigue Crack Closure
Oplt, Tomáš ; Růžička, Milan (referee) ; Horníková, Jana (referee) ; Hutař, Pavel (advisor)
This Ph.D. thesis was written under the supervision of Assoc. prof. Pavel Hutař, Ph.D., and Assoc. prof. Luboš Náhlík, Ph.D. The thesis is focused on the effect of plasticity induced crack closure, its characteristic and ways of numerical modelling. Premature fatigue crack closure has a significant effect on the fatigue crack propagation rate and therefore on the residual lifetime of a structure. A three-dimensional numerical model allows a detailed look at the stress and strain distribution along the crack front, and particularly it allows a local description of parameters along the crack front which governs the fatigue crack propagation rate. In the first part of the thesis, the study is focused on the influence of a singular stress field at the vicinity of the free surface on the crack front curvature without crack closure being involved. In the second part, a numerical model in 2D of plasticity induced crack closure was created and verified by experimental results. In the final part, a 3D numerical model is used to describe the influence of the crack closure on its fatigue propagation rate and explains typical crack front curvature. The suggested technique allows quantitative accuracy improvement of numerical simulation of the fatigue crack propagation and therefore, more reliable estimation of the residual lifetime of the cracked structure.
