Výživa kvasinek během kvašení vín
Kadlec, Lukáš
Nutrition of yeast during fermentation of wine is the topic of this bachelor thesis. The theoretical part is focused on the description of basic yeast species, phases and types of alcoholic fermentation. In particular, it focuses on factors affecting yeast fermentation and nutrition. In experimental part, there are descriptions of three vine varieties, methods of determination of basic analytical parameters, and determination of total assimilable nitrogen in both ammonia and alpha amino acids forms. Design of suitable nutrition.is suggested as well.

Vliv kyseliny askorbové na senzorické a analytické parametry bílých vín
Smrčka, Jakub
This thesis was focused on the effect of ascorbic acid on sensory and analytical parameters of white wine during production technology. The theoretical part is devoted to a detailed description of the mechanisms of oxidation of ascorbic acid and ultimate degradation products of ascorbic acid. In the theoretical part are also given basic methods for the determination of ascorbic acid. Another part focuses on the synergy of ascorbic acid and one of the most important substances in the manufacture of wine, sul-fur dioxide. The practical part includes an attempt was founded in 2014. The study compared different doses of ascorbic acid and sulfur dioxide have been added to the mash two varieties, Riesling and Grüner Veltliner. Attempt monitors antioxidant properties of ascorbic acid and its influence on the analytical and sensory component of the resulting wines. Based on the results, we can conclude that ascorbic acid has antioxidant capabilities asking if it was properly supplemented with sulfur dioxide.

Data Analysis on the Position of Public Transport Vehicles: A Case Study of Most and Litvínov
Zátka, Josef ; Lysák, Jakub (advisor) ; Svoboda, Jan (referee)
The thesis deals with ex post (i.e. not real time) analysis of data on the position of public transport vehicles. The aim of the work is to design and implement spatio-temporal analyses of this data that will be practically applicable to real public transport networks. Their functionality is verified on data from public transport in the towns of Most and Litvínov, recorded during October 2023. The data is a point record with information about the location of the vehicle, the time and date of recording, the line number, the final stop, the last passed stop, the azimuth and speed of the vehicle movement and its delay. A total of 5 analyses are proposed. The first two analyses deal with the possibilities of effective control of the input data, within them algorithms for positional and attribute control of data are presented. The third analysis monitors and evaluates the spatiotemporal differentiation of delays, focusing on trends in the distribution of delays along the routes of individual lines over time of day and over longer time scales. The fourth analysis looks at the occurrence of delays at individual stops. The final analysis studies the reliability of transfers between public transport links at interchanges. The proposed methods were implemented through scripts written in the Python...

Communication Buses in Automotive
Kohout, Robin ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
This bachelor thesis focuses on the comparison of data buses used in the automotive industry in terms of suitability of use and cost. After an introductory section that presents the history and technical parameters of data buses, a description of CAN, LIN, MOST, FlexRay and Ethernet buses follows, which includes basic information, communication mode, connection method, transmission flow and application of the data bus. The final part of the thesis includes a table that allows the reader to get a quick overview of the characteristics of each bus and provides useful information for the correct selection of the bus depending on the specific needs and requirements of the application.

Design of a single span prestressed bridge
Daněčková, Monika ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
This bachelor thesis aims to design a prestressed bridge with one span. The plate girder bridge was selected from the given alternatives. The load effects were calculated by hand calculation using the member model and in SCIA Engineer 22.0. using the slab model. Subsequently, the structure was assessed for limit states.

Prestressed double-T bridge
Padyšák, Lukáš ; Panáček, Josef (referee) ; Koláček, Jan (advisor)
The topic of the bachelor thesis is the design and assessment of the supporting structure of a bridge. Three variants were developed, and the most suitable one was selected from them. The chosen supporting structure of the bridge is designed as a double-T beam made of prestressed concrete with a single span of 30 meters. Midas Civil software were used for the calculation of load effects and time-dependent analysis (TDA). The design and assessment were processed according to applicable European standards.

Information modeling of selected objects of the railway transport route to DTMŽ
Paruza, Filip ; Raška, Jakub (referee) ; Bureš, Jiří (advisor)
The aim of this work is to acquire field data of selected objects of the railway transport route. These are objects such as railway underpass, concrete, prefabricated and steel bridges, plate, beam or arch bearing constructions. The data are acquired using terrestrial positioning systems (TPS) and terrestrial laser scanner (TLS). The data thus acquired are processed into a 3D model of Digital Technical Railway Map with an evaluation of the accuracy and efficiency of the procedures used.

Preparation and implementation of construction and technical survey of prestressed bridge structure
Kummer, Jan ; Kocáb, Dalibor (referee) ; Anton, Ondřej (advisor)
The thesis focuses on a visual excursion with photo documentation, the localisation of prestressing reinforcement of prefabricated beams type DS-T and the analysis of their state as well as the offtake of core drilling in order to establish their strength under pressure. In the theoretical part I describe the principles of the static effect of prestressed concrete and the basic sorting of technical survey and diagnostic methods. Furthermore I explain specific diagnostic methods for the determination of the location and state of prestressing reinforcement. The practical part focuses on photodocumentation of a bridge, the determination of the location of the beams reinforcement using georadar, (chopped probes to reinforcement and removal of core drilling samples. The conclusion provides the location of prestressing reinforcement and the level of its corrosion and grouting, the photo documentation of the bridge and a collection of samples from core drilling in order to determine the strength under pressure of the concrete.

Brickworks and cannery Víchov - Černošín
Lovětinský, Tomáš ; Landa, Karel (referee) ; Pavlovský, Tomáš (advisor)
The subject of the bachelor’s thesis is the design of a facility for producing grape juice and cider on the outskirts of a small village in the Plzeň Region. Víchov, with approximately 120 inhabitants, is located near the town of Stříbro. The main goal of the design is to create a rather pleasant place in the small village associated with highquality apple juice, rather than an austere industrial hall. The gently sloping terrain allows for partial embedding of the production hall below ground level from the side of the village, without disrupting the traditional rural character of the area. The accessible roof and the orientation of the building provide views of the nearby Víchovský pond. Short-term accommodation, a café serving fresh cider and connectivity to the cycling network will attract not only local residents.
