Evaluation of a historically valuable reinforced concrete structure
Uchytilová, Jitka ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
In the theoretical chapters of the bachelor thesis is summary of the historical development of reinforced concrete construction, including individual components of concrete. Furthermore, the issue of the evaluation of historically valuable structures and used diagnostic methods is processed. In the practical chapter there is a diagnostic survey of the selected historical structure including the conceptual design of rescue.
Balancing Exploitation and Exploration via Fully Probabilistic Design of Decision Policies
Kárný, Miroslav ; Hůla, František
Adaptive decision making learns an environment model serving a design of a decision policy. The policy-generated actions influence both the acquired reward and the future knowledge. The optimal policy properly balances exploitation with exploration. The inherent dimensionality\ncurse of decision making under incomplete knowledge prevents the realisation of the optimal design.
Study of rehabilitation of the selected part of the sewerage network in Ostrava
Köhler, David ; Malaník,, Stanislav (referee) ; Raclavský, Jaroslav (advisor)
The aim of the bachelor thesis is to evaluate the current state of knowledge in the area of rehabilitation of sewerage networks. The thesis is divided into theoretical part and practical part. In the theoretical part of the thesis the aim is to describe in detail the process of remediation and presenting the most frequently used rehabilitation technologies. In the practical part of the thesis a practical demonstration of the design of the rehabilitation is carried out on the selected section of the sewerage network in Ostrava. This part of the thesis is broken down into a main text and technical report. Within the practical part, the construction and technical condition of the selected part of the sewer network is assessed, and the design of rehabilitation works, and economic evaluation is carried out.
Effects of melanin-based coloration and commensalism on performance in behavioural tests: a comparative study
Kahounová, Hana ; Frynta, Daniel (advisor) ; Šumbera, Radim (referee)
An intraspecific coat colour polymorphism exists in the genus Acomys. Some populations are dark and others are light-colored. Dark populations live in lava deserts, savannas and in the commensal habitat of Egypt. The subject of this thesis is to compare selected populations of Acomys in behavioral test of forced exploration. They are dark commensal, light secondary non-commensal, light non- commensal, and one dark non-commensal populations. The aim of this research is to find out whether the dark commensal populations of Acomys cahirinus differ in behavior from other populations and whether dark populations differ in behavior from light populations. According to the results, the observed behavioral parameters do not show significant differences between populations. The dark commensal populations of A. cahirinus did not differ significantly from other populations in exploratory behavior. But the dark populations preferred a dark background. No apparent differences in behavior between differently colored populations were found. However, the variability in tested behavior between populations was found. Key words: exploratory behavior, melanin, commensalism, comparative approach, open field test, Acomys
Reimagining academic library user experience: Using mystery shopping to inform service decisionmaking at the Czech National Library of Technology
Orlová, Jana ; Pavelová, Alena
This paper describes how the Czech National Library of Technology (NTK) performed mystery shopping (MS), a technique borrowed from the commercial services sector, as a tool for informing its service decisions and offerings, both virtual and in-person. The methodologies used for two rounds of MS, one in 2014 and another in 2015, are described, and findings and interpretation of feedback in relation to actual NTK service modifications are presented.

Effective visualization for interactive video exploration
Pavlovský, Jan ; Lokoč, Jakub (advisor) ; Grošup, Tomáš (referee)
In this thesis we introduce an innovative approach to visualisation and search results presentation for large video collection search and browsing. The general problem of video search is analysed and discussed in comparison with other current software tools and methods used for video search. A specific visualisa- tion method and algorithm for its generation is then proposed and discussed. We evaluated the methods both, empirically and by a user study. Based on the results, we chose the best possible algorithm settings for interactive video search and applied them. A simple experimental software tool implementing the proposed methods is developed focusing on the visualisation components. 1
Factors influencing variability i behaviour towards novel and aposematic prey in tits (Paridae)
Adamová, Dana
Inter-specific and intra-specific variation in reactions towards novel and aposematic prey was found in several species of tits (Paridae). This Ph.D. thesis is focusing on various factors influencing reactions towards novel and aposematic prey in three European species of tits. We tested differences in exploration behaviour, neophobia, dietary conservatism, personality, age and experience as well as ability of avoidance learning and generalisation. We found no difference in exploration behaviour and in reaction towards novel prey in two different populations of great tits (Parus major). But the birds from the Finnish population were more neophobic than Czech birds, but they attacked aposematic firebug (Pyrrhocoris apterus) more often and faster than Czech birds. The difference can be explained by a different experience with local aposematic prey communities. Than we studied initial wariness in naive juveniles of great tits (P. major), coal tits (Periparus ater) and blue tits (Cyanistes caeruleus), and we tested how the initial wariness towards novel and aposematic prey can be deactivated by experience with palatable prey. Great tits and coal tits from experienced groups significantly decreased their neophobia towards both types of prey while blue tits did not change their strongly neophobic...

Repeatability and personality in tests of exploratory behaviour
Žampachová, Barbora ; Frynta, Daniel (advisor) ; Sedláček, František (referee)
Personality, or behavioural differences among individuals, which are stable both in time and across contexts, is a highly popular topic. Currently there has been an increase of interest in the relationship between personality and repeatability, which is a methodical approach developed to measure the stability of interindividual differences in time. The aim of this thesis is to evaluate the personality of rats according to behavioural patterns exhibited under widely used testing procedures in new environment (open field test, hole board test) and to compare, how behavioural traits in these tests mutually correlate and change over time. Each test trial was repeated eight times with different intervals (24 hours, 6 days, 4 weeks). The results suggest that most of the recorded behavioural variability can be explained with three principal axes. The first one is associated with loco-exploratory activity of the subject. The elements of behaviour associated with this axis are the most repeatable. The second axis is mostly associated with time the animal spent in the central part of the arena and the third axis represents the interest in holes in hole board test. These two axes are less repeatable. A significant effect of the identity of the animal was found in all behavioural traits, associated with these...
Research of teachers opinions on teachers professional development
Straková, Michaela ; Eger, Ludvík (advisor) ; Reichel, Jiří (referee)
The work is focused on the relation of teachers to further their education in conjunction with the current proposal career system. Based on information from the scientific literature, in the work is shown the list of developments further education of teachers in the Czech Republic after 1990, and from secondary sources is defined by its current state. Work also continues to address the career system for teachers, with an emphasis on the text of the selected proposals, including the current one. Through the results of an empirical investigation that was conducted on selected two primary and two secondary schools, are then presented to the views of teachers in these schools watched topics. The dates that were analyzed from empirical investigations are also in conclusion, compared with the theoretical assumptions that are listed in this work. Key words: lifelong learning, development of teachers, education, career system, Ministry of Education, opinion, exploration
