Engine Motormanagement Software
Kopecký, Ivo ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
Fuel injection is a means of metering fuel into an internal combustion engine. In modern automotive applications, fuel metering is one of several functions performed by an "engine management system". A fuel injection system is designed and calibrated specifically for the type(s) of fuel it will handle: gasoline (petrol), Autogas LPG (also known as propane), ethanol, methanol, methane (natural gas), hydrogen or diesel. The majority of fuel injection systems are for gasoline or diesel applications. With the advent of electronic fuel injection, the diesel and gasoline hardware has become quite similar. During the last twenty years a preparation of a fuel mixture and the way of ignition in engine segment have changed the most. Instead of a carburettor it is being used the unit, which prepare fuel mixture according to a status of a car on the road e.g. change of pressure, temperature or ratio of a fuel and air.

A Generator of Arithmetic Circuits
Klhůfek, Jan ; Vašíček, Zdeněk (referee) ; Mrázek, Vojtěch (advisor)
The aim of this bachelor thesis is to present the design and implementation of an arithmetic circuit generator. The generator focuses on generating various output representations of arithmetic circuits in flattened and hierarchical forms using the Python programming language. The work first deals with the specification of HW structures of individual arithmetic circuits and the corresponding ways of describing these structures into various representations. Followed by an introduction to the concept and details of the implementation of a tool called ArithsGen, which is able to generate arithmetic circuits and export them to various output representations. The output representations are then used for fast and simple simulation of the designed circuits (C), to describe the hardware structures and perform logic synthesis (Verilog), to formal verify the designs (BLIF) or to globally optimize the circuits using the evolutionary strategy (CGP). Finally, the generated representations were individually tested and compared with each other using the results obtained from logic synthesis.

Adjoint Differential Equations
Kmenta, Karel ; Pindryč, Milan (referee) ; Kunovský, Jiří (advisor)
This project deals with solving differential equations. The aim is find the correct algorithm transforming differential equations of higher order with time variable coefficients to equivalent systems of differential equations of first order. Subsequently verify its functionality for equations containing the involutioin goniometrical functions and finally implement this algorithm. The reason for this transformation is requirement to solve these differential equations by programme TKSL (Taylor Kunovský simulation language).

Reconfigurabe Waveguide Divider
Cupal, Miroslav
The design and implementation of the textile integrated waveguide (TIW) switch for ISM band is presented. The traveling electromagnetic wave is controlled by conductive posts with a circular slot. PIN diodes are used for switching electromagnetic wave to two directions. The simulations results are presented as parametric analysis.
