Dynamic Scene Model for Mobile Robot
Görig, Jan ; Štancl, Vít (referee) ; Španěl, Michal (advisor)
This master's thesis focuses on representation of geometric information about the surrounding environment for robotic systems. Instead of a common point-cloud based representation, an environment model that stores information about objects described by bounding boxes and planes is proposed. These objects can be obtained from trained object detectors, planar surface detectors, etc. processing data from sensors (e.g. RGB-D camera). The information about the objects (position, etc.) stored in the model is constantly changing according to data obtained from detectors. The environment model is implemented as a module for Robot Operating System. To illustrate and visualize features of the model, a demonstration application was also prepared.

Simulation of circuit breaker maglatch dynamic behaviour
Konšel, Ladislav ; Dostál, Lukáš (referee) ; Valenta, Jiří (advisor)
This work includes the theory of circuit breaker construction and is focused mainly on overload function. It mainly deals with electronic circuit breakers, i.e. equipped with an electronic trip unit. The work is focused on the part of trip unit - maglatch of trip unit. For the purposes of simulation, the geometric model is created. Maxwell program is used for the simulation. The work describes the options for conditions input which are necessary for simulation. Using the distribution of magnetic field intensity and magnetic flux density in the section of trip unit maglatch is determined by the simulation. Furthermore, the force effects acting on the armature of the maglatch are calculated. Force values and the directions acting on the armature are determined by changing the simulation parameters - shift of the armature and coil current. Simulations are performed both for steady-state and for dynamic simulation – movement of armature is taken into account. The supply source for the maglatch is created by an external circuit.

Hierarchical Techniques in Lighting Computation
Ligmajer, Jiří ; Polok, Lukáš (referee) ; Navrátil, Jan (advisor)
This master thesis deals with description of hierarchical techniques in global lighting computation. Here is explaining the importance of hierarchical techniques in lighting computation and shows method, how to use these hierarchical techniques in realtime radiosity and its extension to dynamic area lighting. These two techniques are described in detail in the first part of this project. In the other part is desing and implementation of application for dynamic area lighting computation.

Basic measurement of dynamic properties of bipolar and unipolar transistors
Lang, Radek ; Šotner, Roman (referee) ; Dřínovský, Jiří (advisor)
The aim of this bachelor’s thesis is to describe the dynamic parameters of semiconductor devices. The other aim is to build a measuring workplace, on which is possible to carry out measurement of dynamic properties of bipolar and unipolar transistors. The bachelors’s thesis also solves a design and a production of an universal product, on which measurements are carried out. Individual measurement is automated and individual devices are connected to the product and results are controlled by computer analysis.

The phenomenon of the new
Hodec, Markus E. ; Sepp, Hans Rainer (advisor) ; Stenger, Georg (referee) ; Schmiedl-Neuburg, Hilmar (referee)
The present work on the phenomenon of the new sees itself as an introductory structure of kainology. In doing so, it is pursuing two goals. On the one hand, it seeks the establishment of a new philosophical concept and an independent philosophical method, kainology. On the other hand, the main scope of this investigation applies to the problematization of the phenomenon of the new. In order to take a systematic look at the new, the work is divided into three sections, each of which produces its own partial result. The first section deals with the history of the new. Exemplifying the ontological opposition of Heraclitus and Parmenides, the new emerges as a phenomenon that can be treated more precisely in terms of becoming rather than in terms of being. The second section is dedicated to the method. The kainological method is based on the one hand on dialectics as formulated by Hegel and further developed by Adorno. On the other hand, kainology borrows from the method of phenomenology, namely Husserl's. The complementarity of the two pioneering achievements results in four main methodological elements for kainology: first person singular, from fact to Wesen, the included middle and subject-object. After the history of the new has been traced and the method of kainology established, it is time to examine the...

UAV remote sensing of hydrological processes and fluvial dynamics
Lendzioch, Theodora ; Langhammer, Jakub (advisor) ; Cramer, Michael (referee) ; Hais, Martin (referee)
UAV REMOTE SENSING OF HYDROLOGICAL PROCESSES AND FLUVIAL DYNAMICS THEODORA LENDZIOCH Abstract Using drones and machine or deep learning algorithms (ML or DL) for environmental monitoring offers several advantages over traditional methods, including gathering high spatial resolution data quickly and non-invasively, acquiring real-time data, and covering large and remote areas. This dissertation focuses on snow cover, river granulometry, river sustainability, river bathymetry, and peatland dynamics based on approaches of drone-based imagery that are critical for understanding fluvial processes in mid-mountain regions and their implications for streamflow patterns and ecosystem health. Measuring Snow Depth (SD) and vegetation characteristics like Leaf Area Index (LAI) accurately is essential for effectively predicting snow cover and snowpack persistence across study sites (papers I and III). A further aspect of the fluvial process mediator involves the reproducibility of drone data. This allows for seamless coverage of riverbeds and the determination of ideal parameters for sediment surface cover detection. This can be done through photo-sieving or DL technique, which can analyze Particle Size Distributions (PSDs) of an entire river point bar from top-view UAV images (as described in papers II and V)....

Strength exercises for the prevention of knee injuries in drop landing: a sysmatic review.
Novák, Michal ; Oláh, Vladan (advisor) ; Omcirk, Dan (referee)
Title: Strength exercises for the prevention of knee injuries in drop landing: a sysmatic review. Objectives: This study aims to create an incidence overview of strength exercises for the prevention of knee injuries during drop landing using a systematic search of scientific databases. Methods: For an elaboration of this thesis was used the systematic review method based on recommendations of PRISMA (Page et al., 2021). At the beginning of the thesis, a research question was defined to identify the most common strength exercises in intervention programs to prevent drop landing injuries. Next, a script was created using defined keywords and Boolean operators such as AND, OR and NOT. The script was used to retrieve studies from internet databases (Web of Science, SportDiscus, Scopus, PubMed). Duplicates were subsequently excluded from the retrieved studies, and the number of studies was further reduced by expert review according to predefined criteria. Results: According to the results of this bachelor thesis, lunges are the most common exercise used in intervention programs to prevent knee injuries during drop landing. They were used in 13 out of 24 intervention programs. In addition to strength exercises, plyometric exercises are widely used in intervention programs. Keywords: Strength training,...
