The thesis deals with the reengineering of the Umbrela questionnaire system. The text describes the reasons for reengineering, technology selection, application design, description of basic application blocks and implementation. The work also mentions proposals for improvement of the overall project and its further development.

The Covid-19 pandemic has affected us in different ways and expose the weaknesses of our ecosystem. Some groups of people are more vulnerable to the virus meaning they have to follow the public health authority recommendations with extra caution. At the start of this project, they recommended keeping distance and avoid a crowded environment which makes everyday living harder, especially for groups more vulnerable to the virus. In this thesis, I aim to solve this issue with a web application that extends Coops home delivery of groceries and makes it possible to order extra services as well. The project resulted in an application that is stable enough to use in production today.

This work concentrates on the design and implementation of an automated support for data extraction from product descriptions. This system will be used for e-shop purposes. The work introduces present approaches to information extraction from HTML documents. It focuses chiefly at wrappers and methods for their induction. The visual approach to information extraction is also mentioned. System requirements and basic principles are described in the design part of the work. Next, a detailed description of a path tracing algorithm in document object model is explained. The last section of the work evaluates the results of experiments made with the implemented system.

The aim of this master's thesis is to design and implement JavaScript interpreter which is designed for purposes of avoiding obfuscation code of various types of computer viruses. This master's thesis also comprises a detailed view into the inner mechanism of the ECMAScript standard.

The aim of my thesis is to create a model of information system for internet stores support. Together with creating this model I will also analyse the possible use of new technologies such as AJAX or communication with the help of XML. The final work will consist of two applications, where first is a catalogue of products (goods) and the second is an internet store. The main application will provide services for this store.

The focus of this Master Thesis is creation of a tool for generation of photo galleries, both for personal presentation and as an internet portal for interested exhibitors. The software is aimed at users with no or minimal experience with creating internet applications. The UML language was used for the design, while the web part of the application was implemented with help of the PHP, mySQL, JavaScript and CSS. User interface under the win32 was realised using Microsoft Visual C#. The work is concluded by brief analysis of realistic benefits users get from using the application.

The goal of this master's thesis is an introducing with tools for easy coding and debugging of PHP applications and to implement such tool on the basis of analysis of common requirements and specific requirements of IS VUT designers. The project includes an introduction with important ideas and terms referring to tool, analysis and specifications of requirements and design and implementation of final tool.

This work concerns optimalization of web pages for finders in the way that the web pages could be placed on best positions. The key of success for optimalization of web pages is the combination of some basic rules. The comparison of advantages of different ways of navigation and creation of menu, speed optimalization of pages loading, texts optimalization with the help of chosen key words, principles of choosing the key words, item placing on web pages and comparison of design, marketing and custom view of making the web pages. First of all, we will look on the difference between catalogues and full text finders, their historical development and current ratio of finders on our market. Subsequently we will describe the presumptions for optimalization from the resource code and programming languages point of view, which are used on web pages. The most important part of our interest is the optimalization methods of web pages content and also the methods which are considered as forbidden. The final implementation is made in PHP language.

The objective of this project is to design and create internet shop offering functions, which are common and essential for this type of application. It will also offer functions, which will ensure troublefree and safe run. The base of design are UML models (ER diagram, USE CASE diagram). This models will be created for compact design of database, and structure of whole application. This shop will offer standard administrative functions, which will allow administrators to control the shop. Users will be not only offered by goods, but also will have their own account, where they will be allowed to check the history of their operations. The system will use PHP, html, JavaScript and SQL languages. It will be based on MySql database, Apache server and Rewrite modul of Apache.

Datamängderna som analyseras fortsätter växa (Xu et al., 2022) och SVG (”Scalable Vector Graphics”) och Canvas ligger ofta till grund för 2D-datavisualiseringar (Johnson och Jankun-Kelly, 2008). Samtidigt är det fortsatt viktigt att en webbplats erbjuder god interaktivitet för att inte förlora sina användare p.g.a. undermålig prestanda (Huang, 2005; Babovic, Protic och Milutinovic, 2016). I följande studie jämförs SVG och Canvas genom ett tekniskt experiment för att se vilken av utritningsteknikerna som lämpar sig bäst för att rita ut linjediagram utifrån vatten-relaterad data i ett interaktivitetsperspektiv. Visualieringarna utförs genom två olika JavaScript-bibliotek och resultaten visar att Canvas tillhandahåller en högre nivå av interaktivitet i form av lägre renderingstider vid ”real-time rendering”.
