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.

Time, space and matter: Process-based art
Madar, David ; Hůla, Zdenek (advisor) ; Velíšek, Martin (referee)
The Diploma thesis deals with process art research. Theoretical part is primary focused on theory of Process art, its predecessors, origins and development; resulting in contemporary art, effect of Gallery space and Art market, and controversial positions of Process art. Further it deals with theory of the creation process, artwork's existence and by the process of artifact reception. Pedagogical part is focused on the theoretic base of process in arts education, Proposal and documentation of pedagogic project, based on theoretical work. Practical part - Own project - deals with practical resulting of theoretical part into own project and its defense.

Stretching and the Maximal Muscle Strength
Šádek, Petr ; Konopková, Renata (advisor) ; Otáhal, Jakub (referee)
Title: The effect of stretching on maximal muscle performance Objectives: Due to the number of studies, concerning the effect of the muscle stretch on sport performance and their heterogeneity in the term of used parameters, tests and even performing the stretch exercises themselves, it would be desirable, thanks to the importance of this subject, to consolide and evaluate up-to-date knowledge. The goal of this diploma thesis is to compare and assess available literature concerning the effect of muscle stretch during warmup on the sport performance and, ideally, to define the best type of the stretching itself. Method: The diploma thesis is composed as a literature review - an integrative review with exactly defined criteria for the use of available studies. Result : Even with the nonuniformity of parameters used in available studies there is a consensus in most of the used sources, which met the criteria of inclusion in this research, which (the consensus) determinates the dynamic stretching as the form most appropriate for enhancing the following sport performance. Although studies, proving this result, are in their findings quite unanimous, a precise definition of prefered exercises for peforming the dynamic stretching and of its parameters is still missing. Key words: stretching, dynamic,...

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.

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.
