Small Unmanned Aerial Vehicle for vegetation monitoring
Trojánek, Tomáš ; Pejchar, Jan (referee) ; Dvořák, Petr (advisor)
The aim of this thesis was to select the most appropriate platforms for the fulfillment of required flight mission. The first part reviews available unmanned vehicles suitable for vegetation monitoring and includes both commercially available and self-made types. There are presented basic parameters, recommended equipment and tested configuration of each platform. The second part includes graphical comparison of all models in different categories and the most suitable platform has been selected on its basis. The model project which is based on the selected platform is presented in the final section.

Contemporary UAS and the possibilities of their application to European commercial space
Matejko, Filip ; Šplíchal, Miroslav (referee) ; Vosecký, Slavomír (advisor)
The work contains a brief overview of some modern unmanned aerial systems and later their capabilities of integration into controlled airspace in Europe. It discusses the current legislation dealing with different areas of integration of UAS and the update and developing process of legislation. Another section deals with the exploration of the possibilities of using unmanned aircraft in the commercial sector and their impact on the existing air transportation. The last section is devoted to the technical aspects associated with the integration of UAS into controlled areas. It describes the current systems of the CNS and their possible development in conjunction with UAVs and also a significant part of the work is devoted to the technology of the S&A (Sense and Avoid). During the entire work is gradually evaluate the current situation of the operation of UAS and are designed and recommended necessary changes that will need to be perform to their successful integration into the controlled airspace.

Contemporary UAS and the possibilities of their application to European commercial airspace
Fridrich, Jan ; Chlebek, Jiří (referee) ; Vosecký, Slavomír (advisor)
This bachelor thesis deals with the characterization of legislation for modern unmanned aircraft system (UAS), their commercial use in Europe and the expected development in the future over a period of 3-5 years. In the first part, I focused on the reasons why the category of unmanned aircraft systems was created and described how legislation and individual regulations for the states of the European Union and the European Aviation Safety Agency are created. I selected and summarised the most important legislation in force for the category of unmanned aircraft systems. At the same time, I explained the conditions for registration and flying with UAS and defined the airspace for UAS, which is called U-Space I drew information from the electronic versions of the various regulations published in the Official Journal of the European Union. In the next part, I looked at the CNS technology, which will need to have a UAS in order to communicate with the air traffic controller (ATC). Subsequently, I defined the objectives and possibilities for commercial use of UAS in Europe. The thesis can be used as a qualified aid in studying legislative issues regarding UAS or in theoretical instruction in the branch of Professional Pilot.

Expansion of Skydog Aircraft Model Control System by Remote and Autonomous Control by Android Application
Boček, Michal ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The thesis aims to design and implement an Android application with ability to control the autopilot of the Skydog aircraft model using the wireless telemetry. The application shall receive data from an aircraft model gathered from various installed sensors. These data shall be then processed and corresponding instructions for autopilot shall be sent back. When collision with terrain or obstacle is detected, the application shall send instructions to autopilot to avoid such collision. RRT algorithm is used to find collision-free flight trajectory. Database of known obstacles and digital terrain model are provided to application in formats XML and GeoTIFF respectively.

Analysis of important grass species distribution in the Krkonoše Mts. tundra using remote sensing
Ježek, Vít ; Kupková, Lucie (advisor) ; Červená, Lucie (referee)
Analysis of important grass species distribution in the Krkonoše Mts. tundra using remote sensing Abstract The aim of this thesis was to test the application of maximum likelihood classification, Random forest, Support vector machine and object-oriented classification with the Support vector machine classifier on selected areas in the Krkonoše Mts. relict arctic-alpine tundra for the purpose of mapping the distribution of vegetation with a focus on conservation-important grass species. The research used pre-processed multitemporal hyperspectral data and multispectral data from UAS with a spatial resolution of 0.03 m and 0.06 m and hyperspectral aerial data with a spatial resolution of 0.6 m together with training and validation data collected by botanists directly from the fields using GPS (all data are from 2019-2021). The classifications achieved excellent results. The best overall accuracies were achieved by the object-oriented classification, with accuracies ranging between 80-95 %. Similarly, good results were also achieved by pixel methods - Random forest and Support vector machine (highest overall accuracy 94 %). Of the important grass species, Calamagrostis villosa (producer's accuracy 99.73 %, user's accuracy 99.95 %) and Deschampsia cespitosa (producer's accuracy 99.98 %, user's accuracy 99.33 %)...

GAL4/UAS binary system as a toll for the study of gene function
Soukup, Tomáš ; Krylov, Vladimír (advisor) ; Půta, František (referee)
GAL4/UAS system is a bipartite gene engineering tool, enabling ectopic expression in temporal and tissue-specific manner in vivo. Design of this technique is based on a mechanism of gene transcription, which was elucidated of large portion by an experimental study of Saccharomyces cerevisiae regulation of metabolic control circuit for processing galactose. It is possible to generate hundreds of stable transgenic lines by independent incorporation of the gene for the transcription factor Gal4p and its binding sequence (UAS), respectively, by using transposible or specific-sequence integration techniques. An individual organism, manifesting ectopic expression in suitable, adjustable conditions, can be obtained by cross breeding individual of GAL4 lines with individual from UAS line. This thesis represents a synthesis of the basic principles of GAL4/UAS system and its variants, particularly adapted to the needs of genetic manipulation of model organisms Drosophila melanogaster and Danio rerio. Additionally, this text summarizes the connection GAL4/UAS system with other techniques and briefly highlights the potential for practical applications mainly in research area of neurology.
