This master thesis deals with the design of a traffic sign detector using the image processing methods. The OpenCV library for working with images in programming language Python is used for this. The first part reports on the using methods. In the next part, these methods were tested on images of traffic signs taken in traffic in different lighting conditions. The results of these tests led to the design of optimal methods and their settings, which were re-verified by verifying on video of driving in traffic. This also revealed the conditions under which they can operate in real-time systems. Finally, an optimization algorithm for compensation of detection errors was proposed from the monitoring of detection waveforms.

This paper deals with traffic signs recognition. Red color area is obtained by thresholding in HSV color model. Selected radiometric deskriptors, Hough transform deskriptors and neural networs are used to classification. In conclusion has been designed complex decision algorithm.

The master thesis is divided into two parts. In the first part, identity management is described on theoretical basis. Particular domains of identity management including authentication, authorization and audit are explained as well as Single Sign-On concept, i.e. using single credentials and entering them just once for access to multiple independent systems or services. In the second part, which forms the main part of this thesis, a practical project was implemented on the infrastructure of the Department of Telecommunications within the Faculty of Electrical Engineering and Communication, Brno University of Technology. The goal of this project was to create an environment for central 4 authentication and Single Sign-On using only open source technologies within a computer laboratory used for teaching OS Linux. The project is based on OS Linux Debian, Kerberos as a protocol for secure authentication and LDAP server OpenLDAP. For the Single Sign-On demonstration, NFS services for accessing data on the network were chosen. Using NFS services, users can sign-on to any workstation and access all their data. Administration of users and their import from central FEEC databases was implemented using scripts developed in Python. Next, using Apache, PHP and MySQL, a front-end audit interface for the network administrator was developed in order to inspect and evaluate security events in the network. Messages about suspicious events are delivered to administrator’s mailbox in real time. The project is intended as a security platform which means that other services can be implemented for Single Sign-On as well as new mechanisms for evaluation of suspicious events.

Health literacy (HL) skills are necessary to understand the context of medical information provided to patients in all settings including the emergency room. People with low health literacy (LHL) have difficulty comprehending and implementing basic tasks such as understanding medication administration. The purpose of this quasi-experimental study guided by Orem’s self-care theory was to determine the effect of using the teach-back method for discharge instructions compared to standard written instructions based on parents’ learning style and HL skills assessed during their visit to the emergency room. The Newest Vital Sign (NVS) tool was reworded to assess the parents’ HL. A panel of experts reviewed the tool independently, judged appropriateness and accuracy of the questions, and suggested minor changes. Interrater reliability was assessed in a pilot study with 14 participants, and the strength of the agreement was classified as good (κ = 0.61–0.80) to very good (κ = 0.81–1.00). The NVS was used to determine the literacy levels of 16 participants. The data were analyzed using the Mann-Whitney U test to compare the median scores in comprehension, adherence, and recall. Results revealed no statistically significant increase in comprehension adherence and recall when using the teach-back method (n = 9) compared to the standard written instructions (n = 7). The small sample size was a limitation. Modifying teaching methods for those with LHL to assure complete understanding of important health information will affect positive social change. Further research addressing low health literacy in parents who speak languages other than English is necessary to assure the results are applicable to the general population.

Fairy tale as a space for an art reinterpretation Bc. Monika Švajková Abstract The thesis introduces authors view on the evolution of fairy tales in Europe and its transformation since 19th century in literature, visual arts and related field of knowledge. Its purpose was to create an art project that would connect cultures of Czech Republic and Finland through fairy tales and fine art. Resulting didactical tasks develop fairy tales of one country through contemporary art of the other. The tasks apply to several conceptions of teaching as the implementation took place at the primary art school, high school and lappish art gallery. The art project closes with authors art etudes that expand theme of the forest as an area for updating of fairy tales and simultaneously captures the authors view on the theme of fairy tales. The outcomes and benefits of the thesis were verification of the didactical tasks that would in contemporary art update the classic children literature in context of these two countries.

This diploma thesis deals with a concept of a word and a picture, it compares these two terms, identifies the differences and describes their mutual relationship. It charts those two terms as means of communication and as bearers of meaning. It also describes different ways to combine them in art - it explores presence of a word in paintings in both historical and contemporary art. Didactic part of the thesis is focused on a use of text in art and its meaning. It contains an art project which aims to transfer a text into a picture - to translate a literature into language of art. The project resulted in a series of staged photographic self-portraits representing personal reflection of a topic presented in a literature. Practical part reflects examined relationship of the word and the picture. It refers to the results of the theoretical part and describes author's personal standpoint. Author refers to different ways of connection of the text and fine art and updates them. Author tries to portray a word as a picture which becomes either paradox or harmony.

The thesis investigates one aspect of intracultural communication among the Czech Deaf community. Namely, it surveys those themes which are considered to be taboo among Czech Deaf signers and in which ways they are discussed. This topic is explored from the pragmalinguistic perspective. The meanings of terms such as "taboo" and "euphemism" are explained on the basis of theories of politeness. Thereafter, the topics that are regarded to be taboo in the Czech (hearing) culture are presented, as the source of euphemisms in some foreign sign languages. On the basis of such knowledge, the methodology for a pilot investigation into the tabulation of how communication within the Czech Deaf community was created. Based on semi-structured interviews with five Deaf informants it is examined whether the topics of death, serious diseases, human anatomy and physiology, sexual behavior, social inequality in regards to economic status, as well as socially unacceptable behavior such as drunkenness, lying, stealing and cheating are felt to be taboo during communication among the Czech Deaf community. It was proved that the community tabooed many of these topics in a similar way as the hearing Czech. If the Deaf users of Czech Sign Language need or want to talk about them, they often use such lexemes that could be,...

In this paper we present C. S. Peirce's take on the difference between science and practice in order to identify the role practice plays in his view of the universe. This take is based on a number of notions about the general nature of signs, inquiries, inferences and arguments, which we discuss. We then survey Peirce's classification of science, show the factors it is based on and examine the mutual relations of the various fields of scientific study. This lets us finally posit practice in the realm of qualities and reactions and show the limits of scientific inquiry into certain matters. We illustrate our findings on a number of examples.

This thesis focuses on the basic delimiting of the issue of play within the framework C. S. Peirce's semiotics. Its objective is to expound and explicate the role of the phenomena of play in Peirce's philosophy using selected Peirce's texts and secondary literature, whereas our main starting-point is Peirce's identification of play with the inferential form of abduction. As such play is connected to Peirce's theories of sign and inference, as well as to the concepts of synechism, evolutionary cosmology and pragmatism. This finding sets Peirce's theory of inference within critical logic as one of the key themes of the thesis. In relation to this finding we give a basic explanation of Peirce's phaneroscopy and speculative grammar which in dependency on Peirce's classification of sciences set the ground for our analysis of play as a process of inference as well as a significant function. Within the framework of critical logic we focus primarily on abduction, especially on the question of the validity of abduction as a form of logical reasoning as well as on Peirce's transition from understanding different forms of inference as separate processes to understanding them as a continuous and interdependent whole of the scientific method. We develop Peirce's brief conception of play through an excursion...

The topic of this diploma thesis is semiotic analysis of terms "refugee" and "migrant" in the context of the current migration crisis. The thesis deals with analyzing these terms as semiotic signs. It deals with the way in which selected media treat these terms. Three Czech media were chosen for the research, with 15 selected articles containing research terms from each of them. The sample includes serious news (Aktualne.cz), tabloid news (Blesk.cz) as well as a blog (Blog iDnes.cz) as a journalistic platform, to which anyone can contribute. The research deals with the influence of the media on the formation of concepts and is framed by the theory of social construction of reality presented by T. Luckmann and P. L. Berger. The thesis deals with analysis on the syntactic, semantic and pragmatic levels. In the theoretical part, the theory of social construction of reality is outlined first. Then the thesis briefly introduces the circumstances of the migration crisis and the basic differences in the meaning of the analyzed signifiers and finally introduces the analytical concepts, which are Morris classification of semiotics, Saussure's distinction between syntagmatic and paradigmatic relationships, as well as interrelationships in which individual words can appear in the text. The practical part then...
