This thesis deals with the topic of website optimization and user testing, with focus on the user experience. The main objective of this thesis is to design a software tool for on-line testing of the user experience of web applications, which currently does not exist on the Czech Internet. The first part deals with the user experience in theoretical aspect. It contains a comparison of experts' opinions on the issue and deals with the definition of basic concepts. The theoretical part contains an analysis of research techniques used in designing the user experience, which is an important output for the second part. Practical part of thesis includes at the beginning a research of the availability of tools to support analyzed research techniques on Czech Internet and assess their suitability for implementation into the designed tool. Afterwards thesis follow up the main goal - the development of a software tool for usability testing of web applications and websites (incl. the proposed business model and potential areas for future development). This tool should among other things provide benefits in terms of speed up and simplification of usability testing, including reducing the costs of testing.

A seemingly unexplored territory in teaching computer programming is transcription labs. With transcription referring to "transcribe" in the sense of "to make an exact copy of". In transcription labs students are given the complete code and are asked to transcribe it into their own window before they are able to run it. This approach may be interesting as it forces students to engage with the material more than if they had been given a runnable program outright, while still providing a limited, and in some sense safe, learning environment. This project focuses on creating a web application for transcription labs to serve as a jump-off point into exploration of such labs.  Additionally, this thesis contains a preliminary study that aims at gauging if further exploration of transcription labs is worthwhile. The result of the preliminary study indicates that the answer to that question is yes, it is worthwhile exploring transcription labs further.

This thesis deals with the assessment of the information production system PHARIS and subsequent changes for more efficient management of this information system. The thesis is focused on Manufacturing Execution System (MES). The main objective of the thesis will draft measures and changes to optimize the information system. After introducing these changes should eliminate the weaknesses in the system and bring simplification of working with the system.

This thesis deals with the analysis, proposal and implementation of part of the information system for a selected subject, specifically the proposal of a website including a web application for content management of selected parts of the website. For a successful proposal solution it is very important the first analysis together with requirements of the contracting authority. The graphic design phase occurs after analysis and is followed by the development of the website and the application for content management. After testing and agreement of the proposal solution from the contracting authority the website and application are implemented to the server site. In the final part of the thesis an economic evaluation and benefit’s analysis of the proposal solution are done.

This thesis is dealing with vulnerabilities of web applications. The aim of the work is to create tools for attack detection of certain attacks, specifically Same Origin Method Execution (SOME), XML Signature Wrapping attack, XPATH Injection, HTTP Response Smuggling and Server-Side Includes (SSI) injection. Another aim is to create logs that display detected attacks. In the first part, the theory is analyzed and vulnerabilities of chosen attacks are described including their misuse. In the next section there are web application implemented which contain vulnerabilities for successful execution of the attacks. Furthermore, in Python language detection methods are designed and developed for these attacks, which are accompanied by a log entry.

This master‘s thesis deals with the design and implementation of a web application for the management of diploma theses for students and their supervisors. It defines theoretical starting points for web applications. Based on requirements and analysis of current solutions, it provides a proposal for application, description of implementation, economic evaluation and summary of benefits.

This diploma thesis focuses on the design, development and subsequent implementation of the web application at the company BKB Metal Plc. In that case it is the complete supply ready-made solution. The aim of this work is to develop and implement the web application into corporate environment that will serve as a support of project management and will especially provide the solution for creating visualization by using a Gantt diagram. The impetus for this project was primarily the inconvenient of the current solution, which is not support the key company requirements and as well efforts to reduce costs.

The diploma thesis deals with file sharing among users through peer-to-peer transfer in a web environment. The aim was to create a simple application which would provide a group of users with an opportunity to share files among them without any presence of third party or limitation. I have met the target using modern web technologies, of which the most important was WebRTC library through which peer-to-peer transfer has been implemented. These technologies were supported by optimased algorithm and the most recent tools for processing and storage of shared files. The result is a real-time application enabling users to create rooms, in which they can share their files. This product was subjected to speed tests, thanks to which the application turned out to be the fastest in the tested environment contrary to solutions with similar nature or any other commonly used tools for file sharing.

The aim of this diploma thesis is to design and implement a web application focused on rephotography management. Analyze existing solutions, create list of features and simple graphical user interface. It also includes a design of API structure to communicate with the mobile application. Essential application requirements include adding photos on a map and combining different photos in a photo editor with enhanced auto-alignment features.

This master's thesis deals with Big data processing in distributed system Apache Spark using tools, which allow remotely entry and execution of Spark tasks through web inter- face. Author describes the environment of Spark in the first part, in the next he focuses on the Apache Livy project, which offers REST API to run Spark tasks. Contemporary solutions that allow interactive data analysis are presented. Author further describes his own application design for interactive entry and launch of Spark tasks using graph repre- sentation of them. Author further describes the web part of the application as well as the server part of the application. In next section author presents the implementation of both parts and, last but not least, the demonstration of the result achieved on a typical task. The created application provides an intuitive interface for comfortable working with the Apache Spark environment, creating custom components, and also a number of other options that are standard in today's web applications.
