Fundamental Share Analysis of Selected Gold Mining Companies
Vrľáková, Dominika ; Čáslavová, Iva (referee) ; Rejnuš, Oldřich (advisor)
The diploma thesis deals with fundamental share analyss in order to propose a variant of investing in shares of selected gold mining companies. The subject is macroeconomic analysis of the environment in which selected gold mining companies operate, gold industry analysis and company analysis comprising evaluation of the development of corporate indicators and their issued shares. On the basis of these analyzes ind inter-company comparison, the most profitable options will be proposed to the management of the hedge fund.

Experimental analysis focused on the effect of chloride salt on neutron flux with different energy levels
Slančík, Tomáš ; Števanka, Kamil (referee) ; Katovský, Karel (advisor)
Master’s thesis focuses on the history and current progress in research of molten salt reactors around the world, with an emphasis placed on the properties of molten salts and the problems associated with their use. In relation to the practical part, one chapter is devoted to the creation of input file in the MCNP software. The practical part deals with neutron activation analysis of graphite prism experiment, which is filled with powder NaCl salt. This experiment is focused on the effect of salt on neutron flux with different energy levels. The whole problem was also simulated in the MCNP environment along with the experiment. At the end of the thesis, the individual methods are compared and evaluated.

Proposal for the Creation of an Investment Portfolio of a Fund of Qualified Investors
Kazda, Tomáš ; Brauner, Roman (referee) ; Rejnuš, Oldřich (advisor)
The subject of the bachelor's thesis is the elaboration of a proposal for an investment portfolio of a fund of qualified investors focused on gold mining companies. For this purpose, a model fund is created and it is made a selection of companies according to its statute. After that the companies are analyzed, verified and finally compared to determine the final ratio of individual companies in the fund. At the end of the work, a proposal for the management of the fund with the recommended composition of its portfolio is compiled.

Surface Plasmon Resonances on Colloidal Nanoparticles
Beránek, Jiří ; Brzobohatý,, Oto (referee) ; Šikola, Tomáš (advisor)
The presented diploma thesis is focused on the Localized Surface Plasmons (LSP). The far-field optical response of the colloidal solutions of gold nanoparticles caused by LSP was investigated and compared with the numerical calculations. For the simulations, the Discrete Dipole Approximation (DDA) and Finite-Difference Time Domain (FDTD) techniques were employed. In particular, the shape and size effects of spherical particles and nanorods were studied. The simulations performed by both methods are in a good agreement for the spheres. For the nanorods, the resonance was found to be affected markedly by their geometry. Also, broader resonance peaks were found. This effect was assigned to the sample size distribution and its influence is discussed by comparing the simulations with experiments. In addition, synthesis of nanorods was carried out as well. Finally, the results on the study of optical properties of silver clusters formed under equilibrium conditions are presented.

The Use of Artificial Intelligence on Financial Markets
Hortai, František ; Budík, Jan (referee) ; Dostál, Petr (advisor)
This thesis deals with the design of a model for trading on financial markets by using artificial intelligence. The work describes some methods of artificial intelligence, description of financial market and stock market trading. The result of this work is a model of an expert system which uses fuzzy logic for investing and a functional model for predicting the course of shares trends using artificial neural networks. Both models algorithms were designed and tested in MATLAB.

Nanoparticles preparation by green synthesis
Kortusová, Dominika ; Valušová,, Eva (referee) ; Šimšíková, Michaela (advisor)
This thesis deals with green synthesis of noble metals nanoparticles. The first part contains secondary literature research which maps both the traditional and newly developed techniques of nanoparticles preparation. Most attention is given to the various types of green synthesis, which constitute an environmentally friendly alternative to industrially applied methods. The second part deals with the preparation of noble metal nanoparticles using tea broths. The section describes the entire synthesis process and includes photographic documentation. A total of eight colloidal solutions were prepared, four of each metal. The nanoparticles were subsequently analyzed using UV-vis spectroscopy. A time-lapse spectroscopic description of each synthesis was also undertaken. Furthermore, the size distribution of the particles by volume was measured and compared with the pictures obtained by scanning electron microscopy. The results have showed that tea broths, especially those from black tea and rooibos, are suitable for the biosynthesis of stable noble metal nanoparticles.

Synthesis of colloidal gold nanorods for biomedical applications
Valkovičová, Jiřina ; Bernard, Vladan (referee) ; Drbohlavová, Jana (advisor)
Diplomová práce se zabývá výrobou a využitím zlatých koloidních nanotyčinek v biomedicínských aplikacích. Konkrétně se zaměřuje na tři základní funkce nanočástic v analýze - transportní, separační a především zobrazovací. V části o využití nanočástic pro zobrazování je hlavní zájem věnován zejména povrchové plazmonové rezonanci zlatých nantyčinek. Dále je práce zaměřena na využití nanotyčinek pro termální terapii. Následující část je věnována vhodným modifikacím povrchu, hlavně za účelem zmírnění toxicity částic. Závěrem teoretické části jsou způsoby přípravy zlatých koloidních nanotyčinek a techniky jejich následné analýzy. V navazující experimetální části jsou uvedeny postupy, podmínky a výsledky provedených pokusů.
