NextGen SPICE - Electrical Circuit Simulation Library for .NET
Zikmund, Radek ; Ježek, Pavel (advisor) ; Dingle, Adam Thomas (referee)
The goal of this thesis was to create an extensible library for simulating elec- trical circuits for the .NET platform, which could be used in broad contexts like development of educational programs or applications that use evolutionary algo- rithms to evolve electrical circuits. Our library is inspired by the family of SPICE programs developed at University of California, Berkeley. Initial version of our library implements the transient analysis of electrical circuits and supports basic devices like voltage and current sources, resistors, capacitors, inductors, but also semiconductor diode and BJT transistor devices. Our library is designed in such a way that both new circuit devices and circuit analyses can be added in future versions. Other features of our library include importing circuits or their parts from the industry standard SPICE netlists and ability to modify circuit parameters during the simulation. In this thesis, we also investigate using double-double precision type to improve convergence during the simulation. We also implement a simple SPICE-like console application to allow our sim- ulation library to be used from command line.

Emulator of 8-bit computer with the possibility of configuration of individual components
Fajnor, Jakub ; Kliber, Filip (advisor) ; Ježek, Pavel (referee)
Emulation of the original 8-bit computers may be interesting for many people, es- pecially for true fans of older computers and nostalgic games. Currently, a lot of tools allowing such emulation exist, however, only for specific computer models. The aim of this thesis is to create a library that will enable its user to create models of arbitrary computers using configurable components, that will emulate workings of various parts of a real 8-bit computer. The library is developed on .NET platform and contains several implementations of basic components as a part of this work, including implementation of MOS 6502 processor and some of its descendants. In order not to limit the offer of available components, the library allows easy extension by allowing registration of new components. To demonstrate the use of the library, a simple WinForms application has been cre- ated. Using a graphical interface of the application, the end user of the emulator can create computer configurations and then control and monitor its emulation. 1

GTTG - application for manipulation with train timetable diagrams
Sýkora, Jakub ; Ježek, Pavel (advisor) ; Rosa, Rudolf (referee)
Applications for organization of rail transport often contain visualization of traffic situations, referred to as train timetable diagrams. The goal of this thesis is to create a library that simplifies the development of such applications by providing graphical component which allows developers to implement their own custom train timetable dia- grams. The component, developed for .NET platform, utilizes 2D graphics library SkiaSharp for drawing and can be integrated into various GUI frameworks. The library features interactive rendered content of train timetable diagrams - for example, zooming in on specific areas of the content or clicking on visualized elements. The library also offers an easily extendable implementation of the basic train timetable diagram. As an example of our library utilization, we also developed a WPF application inten- ded for viewing train timetable diagrams of Czech railways. 1
