Comparison of 3D objects in JAVA language
Zapletal, Tomáš ; Smékal, Zdeněk (referee) ; Šmirg, Ondřej (advisor)
The main aim of the thesis is loading of 3D models in different file formats and its displaying, creating of slices from 3D models and vice versa making 3D models from slices, quantify inaccuracy of anti-aliasing and other formatting and investigate similarity of original and edited models. Everything in Java programming language and its extensions for 3D object tasks. Thesis builds on earlier project „3D shape from MRI“.

Design of the supporting frame of lift cage
Zapletal, Tomáš ; Komenda, Lukáš (referee) ; Dvořáček, Jiří (advisor)
This thesis is focusted in design of supporting frame of lift cage. Working load of frame is 1000 kg (13 people). Nominal speed is 2,5 m/s. First part is focusted in design of car frame. Car frame is made from steel bent profiles, connected each other with bolts. This work also contains final elemnt analysis of frame. Structure is analyzed by software Autodesk Inventor.

Deisgn of Reconstruction of the Rapotice - Náměšť nad Oslavou Railway Track
Zapletal, Tomáš ; Andratschke, Jan (referee) ; Hruzíková, Miroslava (advisor)
The aim of this bachelor thesis was to propose a change of track geometrical parametres lining and levelling and a reconstruction of railway superstructure and substructure in the track section Rapotice – Náměšť nad Oslavou. The track section starts at the 19,2 km point of turnout number 5 to the railway station Rapotice and ends at the 22,2 km mark after crossing a steel bridge with a continuous rail bed over the Chvojnice river. The thesis deals with railway drainage, reconstruction of railway crossings and provides a work technology proposal. Study of speed increasing in the track section was solved in the thesis too.

The structure of zooplankton in diet of common bream (Abramis brama) during biomanipulation
Zapletal, T. ; Špaček, J. ; Jurajda, Pavel ; Všetičková, Lucie
The structure of zooplankton in diet of common bream (Abramis brama) was analysed in the Hamry water supply reservoir during the period 2011-2014. Fish were captured by gill netting, beach seining and electrofishing in the littoral part of reservoir. Minimum twenty specimens of each size group were taken for analysis on each sampling occasion. Zooplankton in the diet of adult bream SL 210-315 mm and subadult SL 124-186 mm made recedent proportion. Juvenile bream (0+) SL 18-51 mm consumed zooplankton only. Daphnia galeata was dominant there. We found that decrease of cladoceran communities in the water supply reservoir might to cohere (related) with this specific feeding activity of bream's fry and the feeding competition of bream's and perch's fry in it's habitats.

Biomanipulation measures at the Hamry water supply reservoir - poor reaction of phytoplankton to planctivorous fish reduction
Jurajda, Pavel ; Adámek, Zdeněk ; Janáč, Michal ; Roche, Kevin ; Mikl, Libor ; Rederer, L. ; Zapletal, T. ; Koza, V. ; Špaček, J.
One measure commonly used for improving water quality in open waters is biomanipulation of fish stock. Previous studies in shallow lakes confirm the importance of reducing cyprinid populations for increasing zooplankton. Empirical results from reservoirs, however, are scarce. The aim of this study was to evaluate the effect of an intensive reduction of cyprinid fishes and perch fry density between 2009 and 2013 on water quality in the Hamry drinking water reservoir. The abundance of common bream broodstock decreased by around 12 000 individuals over the five years, and biomass dropped below 20 kg.ha-1. Stocking with pike and zander proved less effective. In reservoirs similar to Hamry, reduction of bream biomass can be a highly effective means of increasing filtering zooplankton biomass. Phytoplankton dynamics, however, appear to depend on additional factors, with nutrient loading (especially phosphorus) probably playing the primary role.

Potrava doprovodných druhů ryb ve vodárenské nádrži
Zapletal, Tomáš
Limnological and hydrobiological parameters were compared with food composition for three fish species (bream, roach, perch) in a meso-eutrophic reservoir (Czech Republic). Fish were sampled using a 100 m beach seine, a fry seine and gillnets at both the lower and upper ends of the reservoir in 2011 and 2012. Food composition was evaluated using gravimetric methods. 0+ bream (36-48 mm standard length) diet consisted of zooplankton only; while in 3-4+ bream (146-186 mm), detritus and aquatic vegetation dominated. In summer, diet of 6-9+ (210-315 mm) bream from beach seines consisted mainly of aquatic vegetation and mainly of detritus when caught in gillnets. Benthic macroinvertebrates and zooplankton were minor dietary components throughout the season. For all roach age groups studied, zooplankton were a negligible food item. Detritus was dominant in 0+ (36-52 mm) and 1+ (72-110 mm) fish. Detritus, periphyton and macrophyte fragments were dominant in 3-4+ (73-163 mm) and 6-8+ (150-266 mm) fish, with benthic macroinvertebrates taken rarely. Zooplankton was dominant in 0+ (16-86 mm) and 1+ (52-81 mm) perch diet. In summer and autumn, cyprinid and perch fry dominated in adult 5-7+ (112-300 mm) fish, while detritus dominated in spring. Benthic macroinvertebrates were recedent. The food intake of bream and roach could be explained the shallowness of the reservoir banks, the rich littoral zone being used for spawning, hiding and for food periphyton. Adult perch play an important role in fish stock management, consuming fish fry that otherwise consumes zooplankton, which subsequently affects phytoplankton levels and water quality.

Valuation of the enterprise ZAPA beton a.s.
Zapletal, Tomáš ; Kislingerová, Eva (advisor) ; Kotáb, Jiří (referee)
The aim of this Master's thesis was to find out enterprise value dated 1.1. 2011, characterise risk connected with this value, for example as a variability of possible results and to judge how the enterprise was affected by the economic crises. I used method discounted cash flow in variant FCFF to calculate enterprise value. I used regression analysis as the basic method to predict the most significant value generator, sales, then I adjusted the results according to the predictions published in qualitative studies of the Czech building industry. The demand for enterprise production was reduced as a result of the economic crises; it enforced production reduction and led to decline in sales and profit in years 2009 and 2010, deteriorating of rentability indicators and long-term assets turnover. I found out the enterprise value with the help of software Crystal Ball also by the stochastic model. In this case I regarded the factors influencing the enterprise value as random quantities. Variability of the possible results ranges between upper and lower limit, i.e. between 1,8 and 3,2 billion crowns.

Finanční analýza podniku AERRO Vodochody a. s.
Zapletal, Tomáš ; Kopalová, Helena (advisor) ; Tyll, Ladislav (referee)
Finanční analýza je důležitou a nezbytnou součástí podnikových financí. Práce musí obsahovat analýzu konkrétního podniku nejméně za tři poslední roky, a to minimálně v podobě vertikální a horizontální analýzy, poměrových ukazatelů, bonitních a bankrotních modelů. Autor práce by se měl zejména zaměřit na vlastní komentáře zjištěných výsledků a na základě jejich zhodnocení navrhnout pro podnik možné další kroky.
