DC arc extinguishing in low voltage switching devices for critical currents
Fencl, Martin ; Šimek, David (referee) ; Píška, Jakub (advisor)
This bachelor’s thesis deals with DC arc extinguishing for critical currents. The first, theoretical part describes and defines an arc, a DC arc and methods of its extinguishing. The second, theoretical part concerns spectral analysis – specifically, the emission method. Methods of research of extinguishing critical currents are also presented. The practical part consists of two measurements. The first measurement consists of spectrum measuring in time, in conjunction with voltage and current measurements. In the second measurement, the goal was to measure the dependence of arc burning time on voltage and current. The thesis concludes with summary of the results of each individual measurement and their presentation in the wider context.

FENCL, Martin. Web based services' conversion rate improvement. Brno, 2015. 155 s. Diploma thesis. Mendelova univerzita v Brně, Provozně ekonomická fa-kulta. Thesis supervisor Ing. Naděžda Chalupová, Ph.D. This thesis is focused at topic of conversion rate improvements in web based services for people seeking jobs. Theoretical basis required for planning of mar-keting research, user testing, implementation of improvements of the service and A/B testing are summarised in chapters 2, 3, 4 and 5 while following chap-ters document practical research, which lead to identification of factors that positively affect conversation rate.

ŘÍZENÍ INFORMATIKY VE VALEO GROUP - ROZDĚLENÍ KOMPETENCÍ
Lisý, Tomáš ; Bruckner, Tomáš (advisor) ; Fencl, Martin (referee)
Text se zabývá řízením informatiky v divizi společnosti Valeo. Hledá nedostatky, které se v poměrně sofistikovaném řízení vyskytují, když je informační systém podle vnitropodnikových principů nasazen do praxe. Využívá pohledu uživatele na IS/ICT a snaží se navrhnout činnosti, které by pomohly zohlednit požadavky uživatelů v divizi. Uživatelský pohled doposud nebyl v provozu informatiky akcentován.
