Proposal to Extend the Investment Portfolio of the Hedge Fund
Hynek, Jan Jaroslav ; Urbánek, Lukáš (referee) ; Rejnuš, Oldřich (advisor)
This bachelor thesis focuses on the creation of proposal to extend the investment portfolio of the hedge fund investing in companies stocks in three selected sectors. In theoretical part of this thesis, legal and theoretical aspects of the operation of hedge fund are described, including individual terms related to this fund. Furthermore, financial analysis is defined in theoretical part there. In the practical part, the fund’s statute and initial selection of suitable companies is specified. Then the selected companies are analyzed, compared and verified by a bankruptcy model. According to all results, in the last part of this thesis the composition of the portfolio is proposed to expand the portfolio of the hedge fund.

Complete series of lanthanide oxalates: Structure and properties
Uríková, Daniela Veronika ; Tyrpekl, Václav (advisor) ; Hynek, Jan (referee)
Metal oxalates are salts of very low solubility allowing an easy precipitation of metal ions from the acidic aqueous solutions into crystalline material. Due to this property, oxalates have an important role in the technology of lanthanides and actinides. It is namely the separation of actinides from the spent nuclear fuel that is its industrial application of interest. 4f-lanthanides are often used as 5f-actinides surrogates when optimizing or modelling the precipitation process. A synthetic route for homogeneous precipitation of oxalates based on the thermal decomposition of oxamic acid was developed by our research team. The present work deals with further investigation into the structure and morphology of simple lanthanide oxalates. The synthesis products, developed microcrystals, were studied by means of solid-state analysis (optical microscopy, single crystal X-ray diffraction, X-ray powder diffraction, TGA, SEM, AFM). Among the known, the previously not-specified structures of Er2(C2O4)3∙6H2O and Yb2(C2O4)3∙6H2O were obtained and refined. According to our observations, the synthesized oxalates form two isostructural series: decahydrates and hexahydrates. Structurally, both types of Ln oxalates form 2D frameworks that are stacked together in one direction and connected by hydrogen bonds to...

Synthesis and properties of zinc hydroxide and zinc oxide nanosheets
Hynek, Jan ; Lang, Kamil (advisor) ; Kovanda, František (referee)
1 Abstract The structure of layered zinc hydroxide intercalated with dodecyl sulfate (LZH-DS) anions was studied in detail. LZH-DS was prepared by direct precipitation in water and formed different phases. The following phases of LZH-DS were prepared - "extended" phase (ex) by direct precipitation in water, "shrunk" (s) and "super-shrunk" (ss) phases via treatment of LZH-DS(ex) phase in methanol. The studies of the thermal behavior of LZH-DS(ex) revealed interstratification of intercalated DS anions. It is the first example of interstratification in layered hydroxides that are intercalated with long aliphatic alkyl chain anions. The experimental results were used for molecular dynamic modelling of the structures. Nanometric thin films were prepared by dip-coating and inkjet printing of ZnO nanosheets on glass plates. The side-by-side alignment of the ZnO nanosheets on the substrate resulted in thin, transparent, oriented ZnO surfaces with the high-energy {001} facets exposed. The method of nanosheet deposition affected the film morphology; the dip-coated films were smooth and nonporous, while the inkjet-printed films were rough and had a surface area in the range of approximately 100-160 m2 g-1 . The first-order rate constants for the photocatalytic degradation of 4-chlorophenol on the nanosheet-based films...

Porphyrin-based porous frameworks
Hynek, Jan ; Lang, Kamil (advisor) ; Zimčík, Petr (referee) ; Dědic, Roman (referee)
Porous frameworks are a class of materials including metal-organic frameworks (MOFs), covalent organic frameworks (COFs) or conjugated microporous polymers (CMPs). Porous frameworks are widely studied as materials for gas storage and separation, catalysis, sensing, drug delivery, water purification, microelectronics, etc. The results presented in the Thesis document that porous frameworks with photoactive porphyrin molecules incorporated in the structure are photosensitizers of singlet oxygen, O2(1 g), and can be used for photodynamic applications including the construction of antibacterial coatings and of organized structures for photodynamic therapy. The Thesis presents a complex study of photophysical properties of porphyrin-based CMPs and COFs and, for the first time, demonstrates the application of porphyrin-based COFs for photodynamic inactivation of microorganisms. The CMPs and COFs were prepared by Suzuki-Miyaura cross-coupling and Schiff base formation, respectively. The materials were characterized by IR and solid-state NMR spectroscopy. The porosity of the materials was determined via N2 adsorption. The CMPs are microporous with pore sizes varying from 1.4 to 2.1 nm and with specific surface areas up to 624 m2 g-1 . On the other hand, the porphyrin-based COFs are only slightly...

Stock market prediction using Twitter
Hynek, Jan ; Krištoufek, Ladislav (advisor) ; Křehlík, Tomáš (referee)
In this work I examine the short-time relationship of Twitter on the markets. I had been downloading English tweets in the period between 9th March and 4th April and also tweets containing words and hashtags "apple", "microsoft", "boe- ing", "cocacola". Afterwards, I investigate the predictive power of frequency of individal words on the marke using multinomial and binomial penalised logistic regression. I conclude that this method cannot be used for prediction, but can provide interesting insight ex-post. 1

Self-report of anger in repressors
HYNEK, Jan
The thesis is focused on repressive coping style and self-reports of the anger. In the theoretical part are elaborated chapters concerning the definition of emotion, emotion regulation, coping and repressive coping style. The Repressors are characterized by unconscious denial of their own anxiety and self-image distortion within the low susceptibility to negative emotions. The research study focuses on the expression of anger by repressors and their comparison with other groups. Respondents (n=122) were divided into four groups using conventional questionnaires (STAI, MCSD): repressors (n=26), high-anxious (n=16), defensive high-anxious (n=47) and low-anxious (n=33). The aim of the study was find out differences in the expression of anger and trait anger. The hypotheses were partly supported, as the results in the expression of anger and trait anger pointed to differences between repressors and low-anxious and partly supported among other groups. The present study shows that repressors distort even other socially censored emotions, in this case anger.
