Broulím, Pavel
Studium "Single Event Effects" (SEE) v polovodičových strukturách

The thesis deals with systems dedicated to time measurement with very high resolution. The resolution is in the order of picoseconds. The necessary part of the systems is their synchronization which is described in the thesis. These kinds of systems with such resolution follow ...

Broulím, Jan
Detekční a opravné kódy

Low Density Parity-Check (LDPC) codes have become very popular because of their near Shannon limit performance when decoded using a probabilistic decoding algorithm. This work proposes several methodologies related to LDPC codes, including design of codes based on optimzation algorithms, mapping&...

Enhanced ionizing radiation detection by several type of detectors

Failures can occur at any time during the lifecycle in all possible condition. The environment in which a car can be used is quite broad. It reaches for example from temperatures of -40°C up to 125°C in the engine compartment. The applied architectures prevent that a ...

Hybridní detektory ionizujícího záření

In recent years semiconductor detectors have proven to be excellent tools to measure ionizing radiation. Hybrid pixel detectors, latest development stage of semiconductor detectors, due to their high cost per area and the typically small unit size, are usually not employed for large...

Žahour, Jiří
Elektronické systémy pro redukci škodlivých emisí u spalovacích motorů

This thesis deals with emissions of nitrogen oxides from combustion engines. The main goal is to design a self-sufficient system for NOx reduction. In the theoretical part of the thesis, the basic principles of NOx formation and their influences on environment are described. Next&#...

Křivka, Jindřich
Řídící a monitorovací systémy pro snižování emisí u vznětových motorů

The doctoral thesis deals with an electronic control system development of electrically regenerable diesel particulate filters. The thesis is dedicated to design of optimal methods for an active regeneration control and an autonomous electronic system initialization. The text contains electronic ...

Elis, Luděk
Řídicí systémy se zvýšenou bezpečností

This thesis deals with the function safety of electronic control system. The first part describes the terms of the system safety in general and presents the comparison of the various fields in which the requirement of safety plays an important role. The design steps of an...

Vlášek, Jakub
Low power systems

This thesis presents a method of data analysis of a multichannel spectroscopic data acquisition system for a large segmented detector of reactor antineutrinos. The method is described, and two implementations are presented. One for PMT based spectrometer for the DANSS detector, built by...

Moldaschl, Jan
Impulsní výkonové síťové nabíjecí a napájecí zdroje

A massive using of switched mode power supplies causes a high harmonic pollution of the line current. The distortion is significant due to a non-linear behaviour of the rectifying diodes and bulky input capacitor of SMPSs. The behaviour causes short spikes of the line current,...

Pušman, Lukáš
Embeded systémy pro lokalizaci a určování polohy

In this thesis a design of a railway-vehicle localization system based on the inertial navigation and specific track-segment detection is described. The system offers an alternative to the traditional solution of the navigation task based on the Kalman filter and it uses primarily ...

Křibský, Petr
Využití moderních průmyslových sběrnic v náročných prostředích

This thesis deals with methods for an estimation of state of charge of lithium ion batteries. This work contains a description of the basic principles of estimation the state of charge. The paper also includes a proposal of an unconventional method for estimation of state ...

Valda, Lukáš
Metody a algoritmy pro vyrovnávání napětí sériově řazených lithiových článků v akumulátorových sestavách

This thesis deals with the issue of balancing series-connected lithium cells in battery-packs, primarily focusing on Li-ion. The first part contains the description of the types of imbalances and their causes, manifestations and consequences, and discusses options for their suppression or el...

Fiala, Pavel
Elektronické komunikace - zpracování signálu v družicových systémech

This doctoral thesis is devoted to the proposal of highly efficient synchronization structures, which can be used within the concept of software defined radio partially implemented on an FPGA. I focus on algorithms for symbol synchronization and carrier phase synchronization. At present,...

Čermák, Karel
Embedded systémy a netradiční způsoby interakce s uživatelem

This thesis deals with the design of embedded platform for didactical aids development. The design was focused for special pedagogues needs in field of specific learning disabilities. On its base, the concrete didactical aids could be derived and they aim to reduce the specific...

Fikar, Pavel
Inženýrské principy v buněčné biologii (Engineering principles in cellular biology)

The use of Dielectrophoresis (DEP) generated by non-uniform electric fields showed to be an interesting alternative to standard flow cytometry technology enabling non-invasive label-free cell measurements. This thesis investigates Dielectrophoretic (DEP) cytometry from three per- spectives. First, the impo...

Kraus, Václav
Datové rozhraní pro řízení experimentu a čtení dat z pixelových detektorů

This Ph.D. thesis devotes to the development of readout electronics for pixel detectors of the Medipix family. The Medipix detectors were developed in frame of the Medipix collaboration at CERN. The data acquisition and control readout interface for pixel particle detector and experimen...

Holík, Michael
Detekce a spektroskopie iontů pomocí pixelových detektorů

The hybrid semiconductor pixel detector Timepix has proven to be a powerful tool in radiation detection and radiation imaging. Energy loss and directional sensitivity as well as particle type resolving power are possible by high resolution particle tracking and per-pixel energy and quan...

Kopal, Josef
Přenos a zpracování signálů

A trigger system is the first part of a data analysis and it is an essential part of modern detectors. It processes and overviews all events in real time and activates an consecutive data acquisition, when defined criteria are satisfied. Thus the trigger system is crit-&#...

Kavalír, Tomáš
Elektronické komunikace (výkonové radioelektronické systémy)
