Implementation of Simple Speech Recognizer in a Web Browser
Crkoň, Jakub ; Glembek, Ondřej (referee) ; Szőke, Igor (advisor)
The goal of this project is to implement simple speech recognizer for web browser. This paper describes fundamental components required for implementing speech recognizer and techniques which are used for optimization process of speech recognition in web browser. At first, the paper focuses on introduction of speech recognition theory. It describes individual parts and principles of speech recognizer. In next section, thesis describes design, implementation and principles of acceleration of speech recognizer with limited computing resources of web browser. The implementation is divided into modules making up the library for usage in web browser. The library is easily extendable and usable in various web applications. Finally, it discusses potential directions of development and usability of this project.

Data Grid in the Web Browser
Mikúšek, Richard ; Dytrych, Jaroslav (referee) ; Máčel, Lukáš (advisor)
This work deals with design and Implementation of data grids component in a web browser environment. The work describes the problems of modern web technologies and their use in implementation of interactive component. A substantial part devoted to the issue of data mining, the deposit, the distribution of elements , the events accompanied by life cycle component. Real use of designed application can be such as a graphical user interface for database or other data source.

Browser and User Fingerprinting for Practical Deployment
Vondráček, Tomáš ; Malinka, Kamil (referee) ; Polčák, Libor (advisor)
The aim of the diploma thesis is to map the information provided by web browsers, which can be used in practice to identify users on websites. The work focuses on obtaining and subsequent analysis of information about devices, browsers and side effects caused by web extensions that mask the identity of users. The acquisition of information is realized by a designed and implemented library in the TypeScript language, which was deployed on 4 commercial websites. The analysis of the obtained information is carried out after a month of operation of the library and focuses on the degree of information obtained, the speed of obtaining information and the stability of information. The dataset shows that up to 94 % of potentially different users have a unique combination of information. The main contribution of this work lies in the created library, design of new methods of obtaining information, optimization of existing methods and the determination of quality and poor quality information based on their level of information, speed of acquisition and stability over time.

Automatic Testing of JavaScript Restrictor Project
Bednář, Martin ; Pluskal, Jan (referee) ; Polčák, Libor (advisor)
The aim of the thesis was to design, implement and evaluate the results of automatic tests for the JavaScript Restrictor project, which is being developed as a web browser extension. The tests are divided into three levels - unit, integration, and system. The Unit Tests verify the behavior of individual features, the Integration Tests verify the correct wrapping of browser API endpoints, and the System Tests check that the extension does not suppress the desired functionality of web pages. The System Tests are implemented for parallel execution in a distributed environment which has succeeded in achieving an almost directly proportional reduction in time with respect to the number of the tested nodes. The benefit of this work is detection of previously unknown errors in the JavaScript Restrictor extension and provision of the necessary information that allowed to fix some of the detected bugs.

Displaying 3D Graphics in Web Browser
Sychra, Tomáš ; Pečiva, Jan (referee) ; Španěl, Michal (advisor)
This thesis discusses possibilities of accelerated 3D scene displaying in a Web browser. In more detail, it deals with WebGL standard and its use in real applications. An application for visualization of volumetric medical data based on JavaScript, WebGL and Three.js library was designed and implemented. Image data are loaded from Google Drive cloud storage. An important part of the application is 3D visualization of the volumetric data based on volume rendering technique called Ray-casting.

PHP Application platform
Špaček, Pavel ; Burget, Radek (referee) ; Martínek, Zdeněk (advisor)
The goal of this work is to create a model of a platform for an application development provided that this platform is implemented in PHP. Applications are built by connecting of functional modules according to desired properties. The run of these applications is provided by the platform.

JavaScript Support in an HTML Rendering Engine
Loskot, Radim ; Kolář, Dušan (referee) ; Burget, Radek (advisor)
This Master's thesis was written to create the extension for an experimental rendering engine CSSBox about scripting support in JavaScript language. In the theoretical section the thesis describes the architecture of the rendering engine and introduces problems of the scripting in HTML documents according to the recommended HTML 5 specification. This thesis deals with thorough analysis of existing scripting engines and their interfaces, which could be used for the extension implementation. Depending on the knowledge gained from the previous parts this thesis focuses only on the scripting engine Rhino and introduces an abstract design of its integration into the CSSBox project. At the end it evaluates the reliability and efficiency of the implemented functionalities and considers possibilities of their further development.

3D Graphics in Web Browser
Kuželová, Ludmila ; Kršek, Přemysl (referee) ; Španěl, Michal (advisor)
The thesis deals with the creation of a three-dimensional virtual view with the use of the new WebGL standard in combination with O3D javascript framework. The result is freely available web application which generates a virtual tour of sent series of photographs. Afterwards, the photographs are processed by the server, which on the basis of found corresponding points creates 3D scene. The application is based on a freeware application Bundler [40] which is used for identifying 3D points in uploaded photographs and related cameras (the places from which the photographs were taken). Bundler outputs are processed by Jetty web server with the use of Java script. At this point, all data required for the creation of a view are gathered. The display of the final result is then realized via HTML5, CSS, WebGL and Javascript using O3D.
