Hybrid module for industrial localization
Sedláček, Petr ; Fuchs, Michal (referee) ; Kubíček, Michal (advisor)
Tato diplomová práce si klade za cíl návrh hybridního lokalizačního zařízení, které je schopno lokalizace uvnitř i vně budov. Lokalizace uvnitř budov je dosažena pomocí technologie Ultra Wideband a venkovní lokalizace je provedena pomocí kombinace technologie RTK GNSS a PPP pomocí open - source softwaru zvaného RTKLIB. První část textu se zaměřuje na vysvětlení používaných technologií a výběr nejpřesnější technologie pro venkovní lokalizaci. Druhá část se zaměřuje ma vývoj potřebného hardware a software finálního zařízení a na integraci systému pro venkovní lokalizaci do systému pro lokalizaci vnitřní. Výstupem práce je plně funkční zařízení, které je schopné plynulé lokalizace uvnitř i vně budov. Funčnost celého zařízení je dokázána na finálních testech uskutečněných ve vnitřních i venkovních prostorách. Na závěr také práce zmiňuje možná vylepšení celého zařízení, která mohou být v budoucnu provedena.

Internet of Things Device Based on Bluetooth and COAP
Fuchs, Ondřej ; Husák, Jiří (referee) ; Musil, Petr (advisor)
This bachelor thesis deals with nowadays very mentioned concept of the Internet of things. The main objective is to define the Internet of things, describe the history of the formation, basic characteristics, development, security issues and the associated risks, trends and possible use. Then describe possible technology and data transfer protocols, manufacturers of device and then outline the future of the Internet of things. Thesis also includes the design, implementation and testing of device falling into the category of Internet of Things.

The effect of nest quality for breeding success in Great Reed Warbler
Jelínek, Václav ; Procházka, Petr (advisor) ; Fuchs, Roman (referee)
Nests are key structures for the reproduction of majority of avian species and as such they should be subject to natural selection. Six hypotheses have been suggested to explain variance in avian nest size. In my master thesis I evaluate their validity in the Great Reed Warbler (Acrocephalus arundinaceus). First two hypotheses describe responses of nest size to predation and brood parasitism. These two selection pressures may lead to the reduction of nest size, but no evidence of their impact on nest dimensions was obtained. However, I found a significant but negative relationship between the probability of nest predation and soft nest height. No such relationship was found between the probability of brood parasitism and nest size characteristics. The incidence of brood parasitism was affected only by nest visibility from the nearest cuckoo perch site and distance from open water. More visible nests suffered heavier parasitism while those located deeper in reed beds were better protected from cuckoo parasitism. Another four hypotheses describe selection pressures which favour large nests or some of their functional parts. The thermoregulatory hypothesis, the sexual display hypothesis and the nest support hypothesis did not explain nest size variation. I found support for the clutch size hypothesis,...

Breeding site fidelity in waterfowl
Kejzlarová, Tereza ; Musil, Petr (advisor) ; Fuchs, Roman (referee)
The thesis is concerned in breeding site fidelity and focused on Anseriformes, especially Anatidae. Higher fidelity ratio in females than in males is an interesting pattern of breeding site fidelity in this bird group. On the contrary, an opposite pattern, i. e. higher fidelity ratio in males prevailed among other bird species. This study is aimed at describing this phenomenon and discussion of factors affecting fidelity ratio. Among, the most important factors, the importance of the previous breeding success and environmental conditions is underlined. The study includes data about fidelity ratio from 40 studies of breeding site fidelity in Anatidae.

Ecology and behaviour of two European pipit species
Petrusková, Tereza ; Fuchs, Roman (advisor) ; Procházka, Petr (referee) ; Matyjasiak, Piotr (referee)
Brief overview of the thesis The thesis consists of íntroductionand five chapters (four published articles and one unpublished manuscript), which deal with two topics unified by the studied species. The first part of the thesis focuses on mechanisms allowing coexistence of tree and meadow pipits, and on the territorial and aggressive behaviour of meadow pipit males. The second part of the thesis analyzes tree pipit song and singing behaviour. Short introduction to the first part presentsbríefbackground on mechanisms allowing coexistence of closely related territorial bird species, and first two chapters focus on local co- occunence of ecologically and morphologically very similar congeneric species: the tree pipit (Anthus trivialis) and the meadow pipít(A. praten'sis).First, we evaluate habitat preferences of these species in syntopy and on two allopatric localities, and show that both species select different habitats in coexistence. ln the next chapter,we test by playback experiments for the presence ofinterspecific territoriality, and conclude that habitat preferences,and not interspecific aggression, are important for territorial selection of the two studied species. In addition, we demonstratethat overexcitation by conspecific song is a factor strongiy influencing behaviour of testedanimals, and...

Productivity of Czech state administration with focus on IT technology and costs connected with use of modern technologies
Fuchs, Pavel ; Pleticha, Petr (advisor) ; Janský, Petr (referee)
Czech state government is often criticized because of slow implementation of new information technologies (IT). Furthermore, IT-related government contracts are frequently overpriced and the official analyses say only little about the projects' efficiency. The paper inquiries into relatively homogenous level of local government represented by municipalities of extended competence. These jurisdictions have to guarantee extensive portfolio of services, however they have relative freedom of investment decision making. We used Data Envelopment Analysis and assigned each municipality with efficiency score. We found out that higher investment in IT does not stand for improved efficiency and indicates inefficiencies in public spending. We also described an ambiguous effect of the size of the district and a significant negative effect of amount of clerks.
