Mapping of motion artefact in fMRI
Nováková, Marie ; Kremláček, Jan (referee) ; Jan, Jiří (advisor)
This thesis summarizes a theory of magnetic resonance and the method of functional magnetic resonance. It is focused on the influence of motion artifacts and image preprocessing methods, especially realign. It deals with the possibility of using movement parameters obtained in the process of alignment of functional scans to create maps that show the expression of motion artifacts. In this thesis, three different methods were designed, implemented a tested. These methods lead to the creation of probability, power and statistical group maps showing areas typically affected by movement artifacts.

Analysis of temporal retinal sequences
Nováková, Marie ; Odstrčilík, Jan (referee) ; Kolář, Radim (advisor)
This thesis deals with a method of the retinal image acquisition by fundus camera, their properties and evaluation of the retinal vessel diameter from acquired images. Several studies dealing with usage of retinal vessels diameters for hypertension, cardiovascular diseases, diabetes mellitus and glaucoma are described. The second part of this thesis is focused on the extraction of the retinal blood-vessels pulsation from retinal sequences and the basic processing of extracted pulsation signals. The proposed method is described in details and tested on one dataset.

Software Tools for the Analysis of Cardiac Depolarization in Patients with Heart Failure
Smíšek, Radovan ; Richter, Aleš (referee) ; Nováková, Marie (referee) ; Kolářová, Jana (advisor)
Heart failure is a disease in which the heart cannot adequately supply the body with oxygenated blood. Approximately 2% of people in the developed world have heart failure, which is increasing. Cardiac resynchronization therapy, which involves the implantation of a biventricular pacemaker, is used in patients with ventricular dyssynchrony to suppress or at least reduce the symptoms of heart failure. The problem is that 30–50% of patients do not benefit from performed resynchronization therapy. The correct patient selection and the pacemaker implantation and set-up method influence the success rate. The thesis proposes methodologies and software to facilitate the selection of patients suitable for cardiac resynchronization therapy, select the correct pacing lead placement, and optimize pacemaker settings. The developed software is based on standard parameters used in clinical practice (QRS duration, presence of left bundle branch block, classification of heart rhythm) and, in addition, on the analysis of ultra-high-frequency ECG, which provides more detailed information on cardiac activation than the standard parameters used. The developed software helps patients in 16 hospitals in the Czech Republic and abroad.

Railway Crossings
Nováková, Anna-Marie ; Hoza, Miroslav (referee) ; Svoboda, Richard (advisor)
This bachelor thesis is focused on the railway crossings problem from the point of meaning of all available legislation. In this work I tried to find out whether all available legislative resources for railway crossings design are identical in their interpretation, as ambiguity of these resources could confuse drivers of vehicles and lead to the big number of traffic accidents. To solve this problem I analyzed all available legislative resources. I determined the most important chapters which context might be interpreted in a different way. Furthermore, I investigated which specific legislative resources deal with the problem and then compared it individually. By completion of this work I figured out that the most important chapters of existing legislative resources don’t contain ambiguity in railway crossing design.

Study of Tram Track in the Veveří Street
Nováková, Anna-Marie ; Janík, Jiří (referee) ; Svoboda, Richard (advisor)
This thesis deals with the relocation of the tram line No. 12 from Kounicova to Veveří Street in Brno city. The No. 12 line will run together with lines No. 3 and No. 11. The proposed line is run in the local communications area. At the intersection of Veveří with Pod Kaštany Street, line No. 12 will be disconnected using the tram triangle, then it will run along Pod Kaštany and Šumavská Streets to Kounicova Street, where it will be reconnected to the original line and with the help of another tram triangle there will be a possibility to continue by the planned track along Šumavská Street. The goal of this thesis is to propose a design of tram superstructure construction, provide a solution for surrounding roads and propose the location of stops, including access to them.

Respite Services for People with Autism and Mental Retardation - Availability in Regions
Nováková, Marie ; Němec, Zbyněk (advisor) ; Hájková, Vanda (referee)
This diploma thesis deals with respite service and issues with providing respite services to parents of children and adults with autism and mental retardation. The opening chapters focus on autistic spectrum disorder in combination with mental retardation and potential challenging behaviour. This work describes therapeutic process for persons with autism and mental retardation and it also describes the issues with providing social service to these persons. This thesis focuses mainly on respite services. The empirical part describes the availability of respite services for families with autistic person and mental retardation in the Czech Republic.
