Evaluation of the Financial Situation in the Company and Proposals to its improvement
Coufal, Denis ; Vozka, Jiří (referee) ; Fojtů, Kateřina (advisor)
The purpose of this bachelor‘s thesis is the evaluation of the financial situation in the selected company in the period from 2014 to 2018 and proposals to its improvements. The theoretical part defines concepths of financial analysis and financial ratios. The practical part puts methods from the previous part in use and calculates individual financial ratios. The final part presents proposals and recommendations to improve the financial situation of the selected company.
Company Development Strategic Framework Proposal with Emphasis on Product Portfolio
Coufal, Denis ; Vozka, Jiří (referee) ; Zich, Robert (advisor)
The purpose of this diploma thesis is a strategic development proposal for a Czech electrotechnical company with an emphasis on a product portfolio. The theoretical basis of this thesis serves as a structure for the analytical and the proposal part. Outputs of the external and internal analysis are the bedrock for formulation of strategic product portfolio development framework at the corporate and business level. The proposal provides a company with a framework for strategic behavior focused on better competitive ability, product portfolio expansion, and delivering higher value for customers of energetic engineering.
Indemnity and Debt Collection in Capital Company
Večeřa, Pavel ; Vozka, Jiří (referee) ; Musilová, Helena (advisor)
The Bachelor's thesis deals with indemnity and debt collection. It has three basic parts – theoretical, analytical, and the part where I propose my own solutions. The theoretical part focuses on the theoretical definition of basic terms, methods of indemnity and debt collection. The analytical part focuses on debt management in ESB Rozvaděče, a.s. The last part describes my own solutions how best to prevent the inception of overdue debts, and if it happened, how best to debt collection.
Optimization of Production Processes
Coufal, Patrik ; Vozka, Jiří (referee) ; Videcká, Zdeňka (advisor)
The theme of this bachelor‘s thesis is to propose a procedure to evaluating nonconformities and folowing to propose corrective measures using tools of quality management in company ESB Rozvaděče a.s. engaged in manufacture of low-voltage switchgear and fitting components for electrical engineering company. The work includes proposed solution for management system of nonconforming products in the manufacture of standard switchboards and specifically for switchgear cabinet SMS-U. The thesis describes the current situation, followed by analysis and proposals to improve the current situation.

Separation of some tryptophan derivatives using cyclofructan based chiral stationary phase
Martínková, Monika ; Tesařová, Eva (advisor) ; Vozka, Jiří (referee)
Chiral stationary phase based on R-naphtylethyl derivatized cyclofructan was used for separation of tryptophan derivatives. In normal mode were tested different compositions of mobile phase and minorite modifiers. The aim of this work was to find suitable separation conditions.
Chemical Experiments in Secondary Education
Vozka, Jiří ; Klímová, Helena (advisor) ; Hybelbauerová, Simona (referee)
The thesis contains four topics from organic chemistry and biochemistry processed into the structure of chemical experiments and laboratory works. These topics are Proteins, Light and fire, Curiosities and Professions. Some experiments are accompanied by motivational text, including additional information or interesting facts. Each experiment was verified in the laboratory at the Department of Teaching & Didactics of Chemistry, Faculty of Science, Charles University in Prague. Each experiment was photographically documented. Two of them were also video taped and these videos with all pictures are on the CD accompanying this thesis.
Characterization of new chiral separation systems for HPLC
Vozka, Jiří ; Tesařová, Eva (advisor) ; Sýkora, David (referee) ; Petr, Jan (referee)
The dissertation thesis is focused on the physico-chemical characterization of interaction mechanisms of chiral stationary phases based on derivatized cyclofructans. Correct interpretation of retention and enantiodiscrimination processes substantially facilitates the development and optimization of new enantioselective methods using cyclofructan-based chiral stationary phases. At first, the interaction mechanisms of three commercially available cyclofructan-based stationary phases were studied in normal-phase mode of liquid chromatography. Namely, systems using chiral stationary phases based on dimethylphenyl carbamate cyclofructan 7, R-naphtylethyl carbamate cyclofructan 6 and isopropyl carbamate cyclofructan 6 were studied. Linear free energy relationship model was used as a basic tool for characterization of interactions on the stationary phases. The mentioned model revealed that the main interactions contributing to retention in cyclofructan-based systems are hydrogen bond acidity and dipolarity/polarizibility, while dispersion interactions cause decrease of retention. The impact of oligosaccharide skeleton of the cyclofructan selector on the enantioselectivity was elucidated by the comparison with seemingly analogous cyclodextrin-based chiral stationary phases. Cyclofructan-based chiral...
