Scientific discoveries inspired by psychoactive plants
KRATOCHVÍL, Lukáš
This thesis deals with psychoactive plants with substances that have been used to increase creativity, openness and insight in the thinking of scientists. The aim of the work is to describe psychoactive plants and substances that were used by scientists during scientific discoveries and to bring these specific discoveries and scientists closer. The search and research method (questionnaire) was used for the solution. A total of 301 respondents filled out the questionnaire voluntarily. Through research, I discovered that the most used psychedelic substances in scientific discoveries were LSD, DMT, and mescaline. These substances are obtained from the following psychoactive plants: Purple sedum (Claviceps purpurea), Reed sedge (Phalaris arundinacea), Mimosia hostilis, Williams's hawthorn (Lopophora williamsii) or San Pedro (Trichocereus pachanoi). This result was also confirmed by the analysis of the results from the questionnaire. The result of this work is that these psychoactive species and substances show great potential for application in various fields, including in scientific research. So they certainly have an effect on creativity, insight and overall mental state. For this reason, further research and more legal benevolence with which subsequent research is associated would be good.

Surveying of stream Lubě between Skalička and Malhostovice
Kučeravý, Peter ; Kratochvíl, Richard (referee) ; Vondrák, Jiří (advisor)
The main subject of bachelor thesis is tachymetric measurement of the Lubě steam valley with close surroundings, including the local communications. This work is dealing with the construction geometric base including its connection into bindings JTSK and Bpv reference systems using GNSS technology, detailed focusing of planimetric and altimetric elements within the site and then processing of the measured data. The result is a tachymetric plan in scale 1:500, the obtained data may by used further for creation DMT.

Thematic map of path and stream in Lubě valley under Paní hora hill
Pačinek, Erik ; Ježek, Jiří (referee) ; Vondrák, Jiří (advisor)
An auxiliary survey network was built in the locality and connected to the bindincg reference system S-JTSK and Bpv. The network was measured using GNSS technology and the polar method. From these designated points of the network, deatailed measurements were made by the tachymmetric method. Obtained values and data from the measurements were processed in relevant geodetic programs. The result of this thesis was to create a thematic map in scale 1: 500 with all necessary documentation. Outputs of the thesis were prepared for eventual handover to DMT creation.

Bioavailability of metals species in water ecosystem
Tandler, Ágnes ; Řezáčová, Veronika (referee) ; Vávrová, Milada (advisor)
Koncentrace volných kovových iontů je často jen malou částí celkové koncentrace kovu v prostředí. Přes tento malý obsah, je ve většině případů koncentrace volných kovových iontů klíčovým faktorem při určování biodostupnosti a toxicity pro organizmus. Membránová technika Donnan se používá k měření koncentrace volných kovových iontů a v této diplomové práci je ověřena pro směsi kovů (Pb + Cu) při absenci a přítomnosti malých organických ligandů. Olovo a měď jsou environmentálně důležité kovy díky své toxicitě a rozdílným vazebným vlastnostem ve vztahu ke studovaným ligandům.

3D model of Kojkovice municipality nerby Třinec
Szturc, Krzysztof ; Berková, Alena (referee) ; Bartoněk, Dalibor (advisor)
The topic of this thesis is creation of 3D model of part of Kojkovice municipality nearby Třinec. It describes the procedure of measuring and processing measured data. Next part contains detailed process of creation of the TINs both from measured data and from ZABAGED data granted by ČÚZK. Model is created using software ArcMap with 3D Analyst extension. Both models are then compared. The result of the thesis is a digital terrain model of chosen area.

Map of open-air museum of Ukrainian-Ruthenian culture in Svidník
Horochonič, Maroš ; Buday, Michal (referee) ; Vondrák, Jiří (advisor)
The subject of the bachelor's thesis is the preparation of a purpose map of the Open-Air Museum of Ukrainian-Ruthenian culture in Svidník. The work deals with the construction of an auxiliary measuring network, including its connection to the binding reference systems S-JTSK and Bpv using GNSS technology, detailed targeting of topography and elevation elements within the site and subsequent processing of measured data. The result is a purpose map at a scale of 1: 500, which can serve as a basis for future project design.

G.fast transmission technology
Zvařič, Filip ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
This diploma thesis focuses on G.fast and VDSL2 technologies and their comparison. G.fast has the prerequisites for replacing VDSL2 for short distances. This work describes in detail the modulation techniques of both DSL technologies - DMT modulation used by both technologies. The aim of this work is to create a software for comparing the transfer rates of all profiles of both technologies, including the effects of far-end crosstalk. This is performed in the Matlab environment. This work describes how the program works and how to run the simulations. The results of selected simulations and their charts are enclosed in this work.
