Biological determinations of cognitive disorders
Vítek, Petr ; Šivicová, Gabriela (advisor) ; Stehlík, Luděk (referee)
As a topic of my bachelor thesis I have chosen "Biological determinants of cognitive disorders". Because of the bachelor thesis' coverage I was forced to choose only two cognitive functions - memory and thinking. This work as a whole is an attempt to combine psychological theories with neurological and psychiatric knowledge which are now popular thanks to the rapid development of imaging techniques of brain. One chapter is specifically focused on their brief summary. In the beginning specific cognitive functions are circumscribed but only two of them are taken further - memory and thinking. More space is dedicated to memory because neurological research of memory is much more complex compared to thinking. My approach is similar in both cognitive functions - at first I focus on description of normal functioning and then I classify and describe specific disorders, trying to find their neurological correlations. The second part of my bachelor thesis proposes the research of episodic memory, in which I would compare differences in its distortions from both neurological and neuropsychological perspective. Patients with delusions, pseudologia fantastica and patients with often confabulations are the target group. I tried to create as realistic design as possible. However I realize its financial...

Design of the tribometr frame by casting technology
Vítek, Petr ; Frýza, Josef (referee) ; Košťál, David (advisor)
This Bachelor´s Thesis presents an engineering design of cast frame for simulator of elastohydrodynamic contact. Original frame is folded from machined parts, which limits shaping and increases the cost of production. Through the analysis of the current state and applicable foundry technologies has been developed design for new cast frame. The output is accompanying report and drawing documentation. The accompanying report documents the prototype production process.

Phenomenon of White
Vítek, Petr ; KRÁLOVÁ, Andrea (advisor) ; SMOLÍK, Robert (referee)
This diploma thesis describes the phenomenon of white color
from the Western world’s culture context point of view. The search
for white color in fine arts and white color as an expression and
an art tool in the theater is the main topic of this thesis. I play
with functions of the color in the theater in a way it can appear
completely non-theatrical due to the theatrical convention, and yet,
it is still widely used nowadays. On the other hand, however, in art,
white has become a conventional color in the gallery space of the
20th century.
In the practical part of the thesis, I reflect two theater projects, in
which I participated as a scenographer in the DISK theater. I am
looking for white leitmotifs in the projects and whether you can talk
about the motive that represents my creative handwriting.

Business plan of the coworking center
Jedličková, Kristýna ; Vrzáček, Petr (advisor) ; Vítek, Petr (referee)
This diploma thesis deals with the phenomenon of shared economy and describes it both on a wide scale and in specific sectors of its use in the social and health sphere. This trend inspired the introduction of a co-working concept to the market which is also described in the theoretical part of the thesis. The theoretical framework of the diploma thesis follows the practical part consisting of interviews with the founder of a co-working centre in Finland, with the executive director of a co-working centre in the Czech Republic, and with two users who have experience with this service in our country and abroad. Qualitative data from semi- structured interviews was a source in the creation of a business plan for the co-working centre, which is the aim of the diploma thesis. At the end of the diploma thesis, there is a shortened methodological guideline for establishing a co-working space. Keywords: shared economy, sharing, co-working, digitization, health and social services, desk

Design of fast magnetorheological damper piston group using selective laser melting technology
Vítek, Petr ; Růžička, Bronislav (referee) ; Strecker, Zbyněk (advisor)
The diploma thesis deals with the development of the magnetic circuit of Magnetoreological (MR) dampers with a short time response. To achieve a short response time, a shape approach was chosen whereby the geometry of the magnetic circuit was chosen to significantly eliminate the occurrence of eddy currents. The influence of structures on magnetic properties was first examined on a simpler toroidal core and then the optimization was subjected to the magnetic circuit of the MR damper itself. Geometry optimization was done using FEM simulations. The resulting geometry was made of pure iron using Selective Laser Melting technology (SLM). In addition, a MR damper was completed and its properties on air and with MR fluid were measured, which were then compared with previously developed rapid MR dampers. It has been found that the newly designed magnetic circuit achieves similar time responses as all other compared fast MR dampers and reaches a higher dynamic range than most of the compared variants. The proposed magnetic circuit also has a significantly reduced weight.

Current Technology Trends in Film Distribution and Their Development
Smrček, Tomáš ; VÍTEK, Petr (advisor) ; DANIELIS, Aleš (referee)
This diploma thesis named Current Technology Trends in Film Distribution and Their Development aims to provide a comprehensive overview of video, audio and other technologies currently used in film distribution. In the introductory chapter it summarizes the history of digitalization and its impact on the discussed technologies. The work then analyzes them from different perspectives: explains their technical principles, describes their evolution, focuses on their use from the perspective of filmmakers, producers, distributors and exhibitors, discusses their financial aspects and lastly focuses on their significance within home entertainment. In one chapter it also analyzes the use of discussed technologies in the Czech film industry. Finally the thesis reflects on the future of technology in cinematography and also determines directions that in the author's opinion cinematography will take from a technological point of view.

The identification of the risk factors and optimization of the follow-up of colorectal cancer patients and their families
Vítek, Petr ; Bureš, Jan (advisor) ; Dítě, Petr (referee) ; Zavoral, Miroslav (referee)
The identification of the risk factors and optimization of the follow-up of colorectal cancer patients and their families Introduction: Patients after colorectal cancer resection are at risk of a recurrence of neoplasia at the site of anastomosis as well as metachronic neoplasias. First-degree relatives of colorectal cancer patients also have a higher risk of the disease that is caused both by hereditary and non-hereditary common factors. Objective: The main goal of the endoscopic part of the project was to evaluate the benefit of chromocolonoscopy with a solution of methylene blue for detection of neoplastic lesions in patients after colorectal cancer resection. The epidemiological part of project was focused on the evaluation of risk factors and current follow-up of patients with colorectal cancer and their families. Methods and results:In the endoscopic part of the work we performed regular white-light colonoscopy followed by chromocolonoscopy in 62 patients after colorectal cancer resection. We used 0.1% solution of methylene blue; total chromocolonoscopy was possible in 94% (58/62) of the patients. Endoscopic and histopathological characteristics of detected lesions were assessed for both methods. Chromocolonoscopy resulted in a statistically highly significant (p < 0.001) higher detection of...

Inclusions in fossil resins
Hähnel, Lydia ; Jehlička, Jan (advisor) ; Vítek, Petr (referee)
My Bachelor thesis, having a background research character, is focused onto amber and its inclusions. In the first part of my thesis, I give some general information on amber: its characteristics and formation, factors for the preservation of inclusions in amber, and distribution of amber. The second part gives a short describtion of methods for amber research. The main focus is on scanning electron microscopy and Raman spectroscopy. I depict some points of the research of geographical and botanical origin of the samples too. As for the last part, I try to get from the rather theoretical explanations to practical points of amber research: what information can amber and its inclusions offer to us? I summarize a few results of amber research which are devided into three groups: information about the climate in which the sample was formed, information on the evolution of life, and information on coexistence of species.
