Travelling and lifting mechanism
Kratochvíl, Michal ; Malach, František (referee) ; Malášek, Jiří (advisor)
The main objective of this work is to design and calculation of handling means for transporting the Bell helicopter between landing area and the storage place. The first part is a literature search with a general overview of producers who are preoccupied with producing the same or similar equipment. Below is an analysis of the applicable mechanisms for handling the helicopter in terms of structure and a summary of some manufacturers. In the second part the design, calculations, technical and design documentation.

Design of screw driven lift
Kratochvíl, Michal ; Klapka, Milan (referee) ; Dvořáček, Jiří (advisor)
This bachelor‘s thesis was created in order to create a new engineering design solutions power unit and lifting device of the lifting platform. Due to the rapid wear of the rope and the increasing cosi, it is necessary to modify this design.. In the first part of this thesis is elaborated research dealing with the issue of lifting equipment. After this section, followed by a proposal and the final design solutions. For the solution variant is prepared drawing documentation.

The first Czech methodology for the assessment of ecological potential of heavily modified water bodies and artificial water bodies based on fish communities was developed. The first step of developing the methodology was preparing the typology of water bodies. The typology distinguishes between water bodies of different altitudes and with and without thermal stratification. Fish were sampled by multimesh gillnets following European standard procedures. The selection of fish metrics was based on statistical analyses in which metrics (fish community indicators) were correlated with the most common stressor – eutrophication. The analysis detected several sensitive metrics (metrics showing the best correlation with the stressor) in which ecological class boundaries were set. Afterwards, combination of sensitive metrics was used for calculation of the ecological quality ratio (EQR) for each of the reservoir sampled. The EQR expresses the deviation between a reservoir’s current ecological status and its maximum potential. The next step consisted of validating the EQR with an independent pressure index and verifying the time stability of ecological potential assessment. The metrics used in the methodology fulfill all the obligations set forth in the Water Framework Directive (2000/60/EC), which include assessment of the composition, abundance and age structure of fish fauna.
