Machine Vision: Support for Lab Applications
Starý, Vojtěch ; Holoubek, Tomáš (referee) ; Matoušek, Radomil (advisor)
This diploma thesis deals with machine vision problematics and its use for laboratory applications. Machine vision is basically the substitution of human vision for machines using a video camera and a computer. The essence of this thesis is a brief review of machine vision and the issues associated with machine vision systems and brief description of hardware, software and algorithms used for this work. Implementation of machine vision on Raspberry Pi and Cognex platform. Connection of the Raspberry Pi platform with a parent platform (automaton, robot) and subsequent evaluation of the solution.

ROS framework and its use in regard to actuation
Starý, Vojtěch ; Dobrovský, Ladislav (referee) ; Hůlka, Tomáš (advisor)
This bachelor thesis deals with the ROS framework and its use. ROS software is an operating system used to control robots. The essence of this work is a brief description of the ROS framework, the process of creating and commissioning your own robot and testing the robot on defined tasks. The first task is to map the simulated environment and the second is autonomous navigation in the simulated environment. The middle part deals with drives.

Round goby (Neogobius melanostomus) in the diet of great cormorant (Phalacrocorax carbo): the role of the season and temperature
Starý, Vojtěch ; Čech, Martin (advisor) ; Adámek, Zdeněk (referee)
Round goby (Neogobius melanostomus) is invasive species, present in the Elbe river since 2015. This study The purpose of this study was to find out how piscivorous predators have adapted to its presence, using the example of the great cormorant (Phalacrocorax carbo). The research was carried out on the basis of the analysis of cormorant's pellets, collected at a locality near Velké Březno (50ř40ʹ34.2ʹʹ N, 14ř07ʹ28.5ʹʹ E) under roosting trees in the period from 1 October 2020 to 15 April 2021, during a total of 7 visits. A total of 1,775 pieces of fish, 15 species belonging to 5 families, were determined from the diagnostic bones. Of this number, 1,115 were round gobies, i.e. a total of 62.8 % of the cormorant's food consisted of these fish. However, the weight share of the total reconstructed weight of all fish caught (113.6 kg) was only very small - 6.6 %. The mean daily food intake (DFI ± S.D.) of cormorants was determined to be 423.7 ± 113.6 g. It was found that cormorants hunting only round gobies overwhelmingly do not consume the necessary prey weight to cover their energy expenditure. Furthermore, the dependence of the size of the hunted prey on the average daily temperature was tested. Linear regression did not show any significant dependence in this case. The hypothesis that at lower...

Impact of changes in the city centre of Ústí nad Labem on the traffic accident
Starý, Vojtěch ; Temelová, Jana (advisor) ; Pospíšilová, Lucie (referee)
Impact of changes in the city centre of Ústí nad Labem on the traffic accident Abstract The objective of this paper is to determine the influence of change of the Ústí nad Labem city center on the road traffic safety. In the first part of the paper the modern modifications of communications in the city centers for the purpose of better safety for the road traffic participants are generally characterized. Further, the paper concerns with revitalization in the centre of Ústí nad Labem. The city centre is represented by three streets (Masarykova, Velká Hradební and Hrnčířská) which have been significantly changed during past seven years. The influence of these changes is compared to the stats of accident frequency and development of traffic intensity in individual streets. The Head of traffic police in Ústí nad Labem, project engineers and the Head of Traffic Department of the municipal government were interviewed to express their opinions on the problems. The result of the paper is an evaluation whether the revitalization of the city center has contributed to better traffic safety.

Reasons and consequences of round goby (Neogobius melanostomus) invasion into the inland waters of Europe and North America
Starý, Vojtěch ; Čech, Martin (advisor) ; Vukićová, Jasna (referee)
Since the end of 1980s there is an ongoing massive invasion of fish from the family Gobiidae. The most widespread and aggressive of these fish is round goby (Neogobius melanostomus). Its natural habitat is area around Black and Caspian Seas, but nowadays it is already common in most of the European rivers, Baltic Sea and in the system of the North American Great Lakes. The main reason of the spreading is transport of ballast water from its natural habitat. The success of its invasion is due to the high tolerance to various factors like temperature, salinity, amount of oxygen in water, food sources and bottom substrates. Presence of the round goby in newly invaded rivers is beneficial for fish-eating predators. On the other hand competitors are highly disadvantaged as they lose in the fight with round goby over food, shelters and places for spawning and therefore, they are forced to live in less suitable habitats which leads to the decrease of their abundance. In recently colonized areas the round goby has much higher abundance than in its original habitats. The highest abundance is in the North America, where the round goby is causing the most noticeable change in the ecosystem. For this reason it is extensively studied mainly in the North America. Keywords: Gobiidae, Neogobius melanostomus,...
