Unity is a game development tool with large userbase. One of the features it is missing, however, is a deeper support for the development of two dimensional games. In particular a tool for editing and generation of two dimensional terrain. The aim of the presented work is to design and develop this tool. First, the problem is analysed and a set of requirements is assembled. Then, the Unity development environment is described in order to be able to use it for implementing the tool. The tool is designed from the programmer's point of view and data representation inside Unity is proposed. Large part of the work is also devoted to describing different algorithms used for terrain generation. Finally, the user interface of the program is designed using the knowledge gained by studying Unity.

The main objective of this dissertation is to provide a novel approach to downscaling of outputs from regional climate models and to simulation of future climate. The resulting method consists of rain generator that operates in 6-hour time step. The generator performs well for the observational data. It consists of following steps: disaggregation of 6-hour cumulative precipitation into convective and stratiform types, fitting of first order 3-state discrete time Markov chain to the data and simulation of long time series of precipitation. Then the mixture of log-normal and Generalized Pareto distribution is fitted to stratiform events and the Generalized extreme value distribution is fitted to convective events. The impact of climate change on precipitation is evaluated by using change factors that are identified for precipitation occurrence (by comparing the transition matrices for the future and control period) and for precipitation amount (by comparing the scale and location parameters of distributions fitted for the future and control period). The observational data are then altered with obtained change factors. From evaluation of observational data it stems that the average volume of an convective event is higher for the western region than for eastern region of the Czech Republic. Additionally, statistically significant trends in number and volume of convective events were identified for the region. The relative portion of convective precipitation is the highest in summer for observational data. From analysis of RCMs simulations, it stems that even though the overall precipitation is projected to be lower in future, the proportion of convective events (versus stratiform ones) would be higher. The number of convective events is projected to be lower in the future, while the volume of a convective event to be bigger.

The aim of this thesis is to research the current possibilities and limitations of automatic generation of synthetic XML documents. The first part of the work discusses the properties of the most used XML data generators and compares them to each other. The next part of the thesis proposes an algorithm for XML data generation which focuses on subset of the main XML data characteristics (number of elements, number of attributes, fan-out, mixed contents etc.). The main target of the algorithm is to generate XML documents using a set of settings which are easy to understand. The last part of the work compares the proposed solution with the existing ones. The comparison focuses on how easy it is to generate XML documents, what structures can be created and finally it compares properties of the similar XML data created using different XML data generators.

This diploma thesis deals with the design and implementation of a communication profile and user interface for already created software core of the network traffic generator. Author introduces the reader to possibilities of creating user interfaces in programming language Java, including a brief evaluation of them. Further, the available low-level tools for network traffic generation are analyzed. Based on the requirements specification is then designed and implemented user interface of the generator, which allows you to manage communication profiles and run individual tests over them. Finally, the project is economically evaluated and future development trends of the application are proposed.

Main objective of this thesis is to extend existing functionality of Integrated Development Environment (IDE) BlueJ with possibility of working with streams in an interactive mode. This new functionality helps to falicitate and improve teaching of programming within the First Architecture methodology. First part of this thesis deals with IDE BlueJ and discusses problematic software con-structions which don´t have sufficient support in interactive mode. Main focus is put on streams. Another part of this thesis suggests possible options for extension which should be integrated to the existing functionality. Following part focuses on analysis of the proposed changes and final part discusses implementation itself and describes author´s process of realization.

In the first part of this work, the digital-to-analog conversion problem and the single-chip microcontroller problem are theoretically described. The HW design of the low-frequency harmonic waveform generator, which is controlled by a microcontroller, is described in the second part. The third part deals with the description of ways how to generate harmonic waveforms using a microcontroller and DA converters. Furthermore, it describes the firmware of the microcontroller. The fourth part presents achieved results and electrical characteristics of the designed generator.
