Dynamic modelling of active railway traction feeders for power quality assessment
Bureš, Jan ; Doleček, Radovan (referee) ; Klusáček, Jan (advisor)
The thesis is focused on modelling of traction feeders for 25 kV 50 Hz traction system in order to assess the influence on voltage quality at point of the connection in 110 kV distribution grid. With respect to various technology of traction feeders, the feeder models, including conventional feeding system and modern converter stations, emphasize operating principle, detailed power circuit structure and description of influence on voltage quality in the distribution grid. The selected technologies of traction feeders are modeled in simulation software PSCAD and influence on voltage quality at the point of connection is assessed via an example, which reflects a realistic operation of traction vehicles in the typical traction system. The models are parametrizable and thus can be used for the connectivity assessment for the distribution system according to national distribution system operators’ standard PNE 33 3430-0. Moreover, the thesis also deals with the use of modern converter feeders for auxiliary frequency services. The operation principle is demonstrated on examples where the basic algorithm and requirements for control layer of converters is described. Finally, an algorithm for synchronization of the feeders supplying adjacent 25 kV 50 Hz railway traction system sections is designed and presented by means of simulation. In general, the thesis shows the use of dynamic models for connectivity assessment to the distribution grid in pre-project phase and for definition and development of converter feeders use cases upon feeding of the railway traction system.
Teaching-space paradigm
Bureš, Jan ; Müller, Rudolf (referee) ; Kristek, Jan (advisor)
The project is dealing with building of a new Faculty of Architecture at BUT. The target area is located on one of the BUT campuses between Údolní, Úvoz and Tvrdého streets. The concept of the new Faculty of Architecture is based on a relationship between teachers and students. The specificity of the architectural studio education is historically referring to beaux art academies. The atelier is a community space where students learn from their "master", but above all from each other. The project addresses the relationship between student´s and teacher´s spaces, which meet in the central "factory" hall, connecting the two worlds.

Electrical models of recuperative loads for electrical railway traction system feeder 25 kV, 50 Hz
Bureš, Jan ; Radil, Lukáš (referee) ; Klusáček, Jan (advisor)
The thesis deals with the modeling of drive vehicles from the point of power consumption and its quality that are being run in the Czech republic on the 25 kV/50 Hz current system. The locomotives being run on Czech territory are categorized according to their electric equipment and typical consumption quality, with respect to the historical evolution. The models of individual categories were created with the help of PSCAD simulation software. A system of control and power parametrization of models was also designed, based on the outer description, i. e. parameters of locomotives, line profile and the driving dynamics. Thus, the designed models are suitable for the simulation of energy flow profile in the traction system as a whole.

Software for Design of Timetables
Bureš, Jan ; Mlích, Jozef (referee) ; Zemčík, Pavel (advisor)
The aim of this thesis is to design a software for elementary, middle and high schools, which will serve to create alternative timetables for staff substitutions. There are similarly oriented programs, but most schools don't use them. These programs contain many flaws, which are also discussed in this work. Creating substitution schedules is complicated, and a lot of conditions must be taken care of. Checking of all the conditions should be the main advantage of the application. Design and implementation of the application is based on requirements by a school, where substitution timetables are produced manually. Great emphasis is placed on user friendliness and ease of use.
Gastroparesis - pathophysiology, etiopathogenesis and possibilities of endoscopic treatment
Husťak, Rastislav ; Martínek, Jan (advisor) ; Bureš, Jan (referee) ; Urban, Ondřej (referee)
Background: Gastroparesis (GP) is a disorder characterized by delayed gastric emptying in the absence of a symptomatic mechanical obstruction of the stomach with cardinal symptoms. Two principal pathophysiological mechanisms are believed to be responsible for development of GP: global gastric hypomotility and pylorospasm. As pylorospasm may play an important role in GP, the efficacy of treatment modalities targeting the pylorus, such as gastric peroral endoscopic pyloromyotomy (G-POEM), is currently being intensively studied, as these methods have the potential to help especially patients with severe symptoms for whom other treatment measures are ineffective. The aims of our studies were: (1) to evaluate clinical efficacy of G-POEM in the treatment of patients with severe GP; (2) to evaluate the changes in objective periprocedural parameters measured by gastric emptying study (GES) and functional planimetry; (3) to evaluate safety of G-POEM and (4) to compare the efficacy of two closure methods used to close the mucosal incision in G-POEM: clips and endoscopic suturing (ES). Patients and methods: Patients older > 18y, with gastroparesis cardinal symptoms index (GCSI) > 2.3 and abnormal GES were eligible for inclusion. All projects had been performed between 2015 and 2021. Project (1): Clinical efficacy of...
