Price Elasticity of Demand and Special Discounts
Zeman, Jaroslav ; Škrdlík, Miloš (referee) ; Bayerová, Vladimíra (advisor)
This master thesis deals with the issue of special discounts. Assessments and proposals of successful special offers are based on the analysis of demand price elasticity. The key attribute of this work is the knowledge of product’s price elasticity of demand. The analysis of price elasticity of demand is based on real data. The paper is terminated with suggestions on creating and planning special discounts developed in consideration of the retailers’ specific goals.

Rheological study of high-molecular weight hyaluronan-protonated aminoacids interactions
Zeman, Jan ; Běťák, Jiří (referee) ; Chytil, Martin (advisor)
The study deals with interactions of hyaluronic acid with protonized amino acids Lysin and 6-aminocaproic acid. To study the interactions pH-metry, conductance measurement and reometry were used. The mixtures of hyaluronan and the aminoacids of different concentrations were measured and the data were compered with data obtained from measurement of amino acid samples in pure water. Observed interactions occured in the aminoacids concentrations between 0 to 10 mmolxdm3, then the HyA carboxylic groups were fully bonded by amino acids and no more interactions were recognized.

Investigation of Polyelectrolytes Interactions with Cationic Aminogroups-containing Amphiphiles
Zeman, Jan ; Běťák, Jiří (referee) ; Chytil, Martin (advisor)
The study deals with interactions of polyelectrolytes polystyrene sulfonate and hyaluronic acid with nitrogenic amphiphilic substances, represented by lysine and albumine. To study the interactions pH-metry, conductance, viscositic and turbidity measurement, DLS and reometry were used. All mixtures of different concentrations were measured and the data were compered with data obtained from measurement of samples with amphiphilic sumstances without polyelectrolytes. Observed interactions occured in the aminoacid concentrations between 0 to 20 mmoldm-3, then the PSS interaction groups were fully bonded by lysine and no more interactions were recognized. The same behaviour were observed in albumine solutions with concentration under 2 gdm-3.

3D scanning of glossy surfaces
Zeman, Jakub ; Zatočilová, Aneta (referee) ; Koutecký, Tomáš (advisor)
The goal of this bachelor thesis is to experimentally determine the impact of different concentrations of titanium matte coating on the properties of matte film covering glossy surface intended for 3D scanning. Theoretical part of the thesis contains brief introduction to the 3D digitization of real objects as well as more detailed description of the particular scanning method used in this thesis and summary of possible digitizing errors and existing knowledge about matte coatings. The practical part composes of applying the titanium matte coating on specimens using automated coating device thus maintaining the exact same conditions for all concentrations. Following measurement of specimens using 3D scanner and optical profilometer results in determining the optimal concentration of titanium coating providing the best properties of the matte film.

Experimental Assessment of Influence of Polyethylene Liners' Position on Plastic Deformation in the Run-in Phase of Wear
Zeman, Jakub ; Daniel, Matej (referee) ; Ranuša, Matúš (advisor)
The diploma thesis is focused on the run-in phase of total hip replacement. Mutual adjustment of contact surfaces takes place in this phase and polyethylene acetabular cup shows notable creep behaviour. The magnitude of creep deformations is assessed experimentally in relation to acetabular cups orientation in human body after its implantation. The condition of articulating surfaces is also assessed as well as resulting coefficient of friction in run-in phase. Physiological load and kinematics of the artificial joint as well as physiological conditioning is achieved by new module of existing joint simulator, which is created as part of this thesis. Deformations and condition of articulating surfaces are assessed via optical methods and SEM. Findings about the run-in phase are compared with existing FEM analyses to evaluate simplifications used in these analyses. Measurement of creep deformations has also potential to improve the accuracy of acetabular wear diagnosis in clinical practice.

Analysis of the Financial Situation of a Company Using Time Series
Zeman, Jaroslav ; Novotná, Veronika (referee) ; Doubravský, Karel (advisor)
The bachelor thesis analyses the financial situation of the company using statistical methods of time series and regression analysis. The first chapter is focused on clarifying the elementary theory of the issue. The theoretical knowledge in the second chapter is applied to the financial statements of the company. Based on the results of the analysis there are prognoses of the future development and suggestions for improvement of the economic situation of the company.
