Hydraulic analysis in the surrounding of hydro power plant
Lorenc, Václav ; Roth, Tomáš (referee) ; Duchan, David (advisor)
The diploma thesis deals with analysis of flow ratios at the hydraulic plant Klecany – Roztoky, located in the region of Střední Čechy at Vltava river (km 37,08). At this site 3D streaming of superficial water was simulated aiming to evaluate the influence of potencial construction of the new hydroelectric power plant Klecany II on existing Klecany I. Using all of the base documentation available, 3D models of current and planned conditions were created to serve as base for calculation in FLOW 3D. The first part of the thesis describes, how the planned construction of the new hydroelectric power plant Klecany II could influence the current fairway at the inlet 400 m3/s. The second part analyses shape of planned flow hydroelectric power plant Klecany II for flow Q90d, equal to 180 m3/s. All of the results are presented in intelligible charts and images.

Estimating the flow capacity of river
Lorenc, Václav ; Dráb, Aleš (referee) ; Duchan, David (advisor)
The bachelor thesis is dealing with the watercourse`s capacity assessment of the river Jihlava on the kilometers 136,5 to 139,5 in the village Maly Beranov. In the chosen locality was made a model of the surface water flow during the flood flow rate Q1, Q5, Q20 and Q100. Based on the gathered information about the area`s utilization, errand and following calculation of the flow, the areas for a potential flood protection were identified. In the problematic locations was suggested to dredge the bottom. In selected sections was made a draft of protective earth dam and concrete wall. According to the draft of flood protection, the model of surface water flow was adapted and the efficiency of flood protection was verified by calculations. All the results are published in clear maps.

Application of behavioural economics on pricing page.
Oravec, Jakub ; Stříteský, Václav (advisor) ; Lorenc, Václav (referee)
This paper discuses design and optimization of the price lists on the web-sites, using the knowledge acquired from the field of behavioural economics. To support the main goal of this paper, the quantitative experiment was conducted. This experiment was conducted through the web-site, where two different types of prices, set by application of a knowledge from behavioural economics and architecture of a choice were tested. To evaluate the data obtained, the descriptive statistics, hypothesis testing and revenue impact analysis have been used. Applying the data obtained as a result of the experiment, it has been found that different factors can influence the decision-making process and preferences of an individual deciding between different types of services. This testing proved the relation between the price list displayed and the choice of a subject of this experiment. At the same time, it was found that by using the best suitable design architecture of the online price list and by applying knowledge from the behavioural sciences, it is possible to positively influence the sale revenue and conversion of the chosen variant, with relatively low implementation costs, as it is demonstrated on the example of Czech market.
