Design of an AD converter for sensor applications
Bečková, Zuzana ; Kubánek, David (referee) ; Jeřábek, Jan (advisor)
Diplomová práce obsahuje stručný teoretický základ pro designéra/ku A/D převodníku v technologii CMOS a přehled architektur A/D převodníků používaných v automobilovém průmyslu. Volba vhodné architektury pro konkrétní aplikaci byla zásadním úkolem zpra- covaným v semestrálním projektu předcházejícím tuto práci a je rovněž součástí této práce. Analýza v Matlabu, ze které by mělo vyplynout, je-li třeba zahrnout do architek- tury podblok Sample and Hold, je také součástí práce. Klíčovou částí práce je dokumen- tace návrhu jednotlivých podbloků A/D převodníku – operačního zesilovače, kompará- toru a R-2R D/A převodníku – a ověření jejich funkčnosti. V závěru práce je ověřena funkčnost A/D převodníku jako celku.

The influence of electrolyte additives to lead-acid batteries properties
Dohnal, Martin ; Zimáková, Jana (referee) ; Bača, Petr (advisor)
This day is a lead battery is most prevalent in the automotive industry. Which is a source of energy when starting the car. In recent times the battery is used not only for startups, but also when driving in city traffic. This behavior can know the concept of a hybrid car. Which is used an electric motor which as a result reduce emissions standing cars in cities. The electric motor is powered by lead-acid battery and a rapid discharging and reducing battery life. To extend the life developed additives to the electrolyte. In the thesis, these additives investigated. If they really have a positive effect on the battery.

Critical Factors of ERP System Implementation for Employees Training Management in HELLA AUTOTECHNIK NOVA, Ltd.
Bill, Štěpán ; Schwarz, Jaroslav (referee) ; Sodomka, Petr (advisor)
The aim of this thesis is to compile a manual guide for choosing an appropriate information system to support the company e-learning process. I solved this particular problem by conducting both the analysis of the company and of the current trends in e-learning applications. I also assessed the existing situation and determined system requirements of the company. By carrying out my own survey I found out that implementing the optimal software helps to educate employees more effectively and brings savings and potential profits for the whole firm. The outcome of the thesis is a set of recommendations for the right choice of e-learning software as well as critical factors for the e-learning implementation project.
