Software support for cryptography education
Stančík, Peter ; Vyoral, Josef (referee) ; Burda, Karel (advisor)
The main aim of this thesis was to study, choose and decribe techniques eligible for cryptography education. A pedagogically appropriate presentation for the selected techniques' principles was to be chosen. Another goal was to create an integrated modular web interface containing a calculator focused on cryptographic operations. The eligibility of techniques was assessed accordingly to the computing processes implied by these techniques and also accordingly to the ability of being presented in an illustrative way. A program simplifying calculations used in symetric and asymetric cryptography was designed and implemented. It disposes of a web interface and one of its parts is focused on steganographic techniques. On the other hand, any pedagogically appropriate presentation interconnecting this program with theoretical findings from this field was not found.

Educational Game of Motivation on the Android Platform
Kučera, Martin ; Očenášek, Pavel (referee) ; Kreslíková, Jitka (advisor)
The aim of the dissertation is to create a prototype of an educational game which should help students with the choice of future their studies. To this end, the game introduces the topic of logic systems in a non-threating interactive way with clear illustrative examples. The theoretical part of the work deals with the background knowledge necessary in order to design the game. It explains logic systems, gates, flip-flop circuits, and explores various aspects of game genres with primary focus on puzzle games and their history. In addition, the dissertation presents some of the issues related to cross-platform development of games for both mobile and computer platforms, and provides brief descriptions of several popular cross-platform libraries. Lastly, the work introduces and compares several chosen applications created as a supplementary material for teaching logic system.

REFLEKTOR - Web System for Teaching Support
Sitko, Radek ; Grulich, Lukáš (referee) ; Martinek, David (advisor)
This thesis deals with design and implementation of a web application to support interactive tuition in programming within the IZP - Course of Programming Essentials. It enables students submit their own solutions to a specific task and allows them to review some tasks completed by other students. Web pages are created with respect to maximum accessibility of their content and functionality. Their layout and controls are designed in such manner to make them accessible both by alternative browsers as well as by people with specific needs. The application design is created using the UML modelling language. The very application is implemented using the PHP script language together with theXHTML, cascade style sheets (CCS) and the MySQL database system. This thesis also focuses on implementation of the system on FIT websites and its utilisation by students.

Software support of education in classical cryptoanalysis
Fojtová, Lucie ; Hajný, Jan (referee) ; Burda, Karel (advisor)
Number of today's modern cipher systems are based on the classical symmetric cipher systems, such as the transposition principle in the DES cipher. Successful analysis and deciphering of these ciphers is therefore underlined by solid knowledge of the elementary cryptanalysis methods. This implies the importance of classical cryptanalysis education -- for better a understanding of the field, using visual means is of utmost importance. The aim of the thesis is to summarize selected cipher methods of the classical cryptanalysis, namely the mono-- and polyalphabetical substitution and transposition route cipher. Along with the theoretical part, ciphering/deciphering software is introduced to be used for educational purposes, particularly a website and a standalone application providing tools for ciphering, analysis and code breaking of the classical cipher based code.

Software support of education in cryptography based on integer factorization
Vychodil, Petr ; Martinásek, Zdeněk (referee) ; Burda, Karel (advisor)
This thesis deals with new teaching software, which supports asymmetric encryption algorithms based on the issue of large numbers´ factorization. A model program was created. It allows to carry out operations related to encryption and decryption with an interactive control. There is a simple way to understand the principle of the RSA encryption method with its help. The encryption of algorithms is generally analysed in chapters 1,2. Chapters 3 and 4 deals with RSA encryption algorithm in much more details, and it also describes the principles of the acquisition, management and usage of encryption keys. Chapters 5 suggest choosing of appropriate technologies for the creation of the final software product, which allow an appropriate way to present the characteristics of the extended RSA encryption algorithm. The final software product is the java applet. Aplet is described in the chaprers 6 and 7. It is divided into a theoretical and practical part. The theoretical part presents general information about the RSA encryption algorithm. The practical part allows the users of the program to have a try at tasks connected with the RSA algorthm in their own computers. The last part of Java applet deals with the users´ work results. The information obtained by the user in the various sections of the program are satisfactory enough to understand the principle of this algorithm´s operations.

Demonstration of an Indexing Algorithm kD Tree and Its Derivatives
Foukal, Tomáš ; Květoňová, Šárka (referee) ; Kolář, Dušan (advisor)
This thesis deals with analysis, designing and implementation of an application for teaching of indexing algorithm kD Tree and its derivates. Also, it deals with testing the application, describing of its use and including examples with exact data. Application as well offers a~possibility of running of algorithms step-by-step and their visualization with a graphical user interface. During development, the emphasis was on executability of the application in all major web browsers.

Applications supporting lectures on colour models
Khaladzinski, Kiryl ; Záviška, Pavel (referee) ; Rajmic, Pavel (advisor)
The aim of this bachelor thesis is to create Web applications that show the possibilities of working with different color models in real examples shows principles of digital images creation and the possibility of processing digital image data. Theoretical part devoted to the basic concept in color theory and the basis of raster images. The practical part is the design of four applications and their creation. The first of the applets shows the principle of mixing colors in different color models, the second on the example shows the basis of the index representation of the image, the third shows the methods of translating the color image to grayscale and the last applet is used to translate grayscale image to color image.

Presentation Software for Physics on Elementary Schools
Matoušek, Miroslav ; Seeman, Michal (referee) ; Štancl, Vít (advisor)
This final thesis deals with the software supporting the education through the presenting the physical process. Specifically, it deals with the kinematics on the level of the basic school and secondary school. Next there are described the basics of pedagogy, didactics, simulation and modelling referring to the suggested programme. There is also a suggested system and its graphic user interface based on the gained findings which is later implemented.

Koncepce, podpora a zkušenosti z výuky v oblasti zobrazovacích systémů na ČVUT FBMI ve studijním programu Biomedicínská technika
Hozman, Jiří ; Volf, Petr ; Krupička, Radim ; Mardanshina, Evgeniia
V příspěvku jsou shrnuty zkušenosti za posledních 30 let z hlediska výuky problematiky zobrazovacích systémů v lékařství. Za tuto dobu bylo vyzkoušeno několik modelů výuky, a to zejména z hlediska počtu předmětů a rozsahu, ale také metod výuky, a to jak na ČVUT FEL, tak i převážně na ČVUT FBMI, ale i na 1. LF UK. Ve všech případech se jednalo o bakalářská a navazující magisterská studia, která mají vztah k biomedicínské technice, resp. biomedicínskému inženýrství. Tyto dlouholeté zkušenosti pak vedly k vytvoření vhodné struktury přednášek a cvičení, ale i k vytvoření vhodné podpory výuky. V uvedeném příspěvku jsou všechny tyto aspekty zahrnuty. Jedná se tedy spíše o jistý souhrn dosažených zkušeností a doporučení, tzv. dobré výukové praxe, kterou lze využít i na jiných VŠ.
