Slate gas and the future of its energy exploitation
Šindler, Matěj ; Přibil, Rudolf (advisor) ; Jelínek, Emil (referee)
First part of bachelor thesis introduces the concept of shale gas - what is the nature of the gas, why it is called shale, etc. Then there is described the technology of mining and acquisition of gas. Another chapter informs about shale gas reserves in the world, its importance and the planned career intentions. Very important part of this work is to look at the impacts of extraction of this gas, in particular climate change, water and soil pollution, impacts on the population, but also other phenomena, such as earthquakes caused by the extraction of this shale gas. The last part is the chapter on the current situation of shale gas exploration in the Czech Republic. At the conclusion, the whole situation regarding shale gas is evaluated and my own views on this extraction are presented.

Ověření možnosti dlouhodobě udržitelné akvakultury na Boheľovakých rybnících
ŠINDLER, Martin
The focus of the thesis was verifying the effects of fish breeding in production-oriented fish farming on the ecosystem of fish ponds. The observation was conducted in R1 and R3 Boheľov fish ponds in 2014 and 2016 seasons. The RKK and SGR parameters, the natural fish pond production and the overall production were monitored. The monitored chemical and physical parameters included the developments of the essential parameters at two-week intervals; oxygen, pH, transparency, temperature and insoluble substances. Chlorophyll-a, total phosphorus and total nitrogen were monitored to assess the timely trophy in the ponds. To assess the effects on water organism community zooplankton succession by Cladocera, Copepoda and Rotifera taxonomic orders was monitored at two-week intervals. The monitoring also included periodical checking of the biomass of undesired fish that reached the value of 44,5 kg.ha-1 in the R3 pond. Roach (Rutilus rutilus) was the dominating specie. Control fishing was carried out during the seasons to estimate the actual biomass of carp stock. The total production ranged between 922,1 - 1181,5 kg.ha-1. The RKK level was 2,73 - 3,26. The SGR value of 0,902 %.day-1 was reached in stock C1-2. High carp stock influenced the zooplankton communities. During the observation no occurrence of the intermediate zooplankton was found. The prevailing species of the Cladocera order included Bosmina longirostris, Dafnia galeata and D. parvula. In the Cladocera order there was prevalence of Acanthocyclops trajani and in rotifera order there was prevalence of Brachionus calycifloris, Asplanchna priodonta, Polyartha sp. Spearman's correlation confirmed difference between the total zooplankton in R1 pond compared with R3 pond in both seasons (R3 2014: rho=0,066; pval=0,854; R3 2016 rho=-0,018; pval=0,96). The TSI index showed hypertrophic condition in both ponds. The average values of the index were 78,3 (6,2) in R1 and 75,6 (?3,8) in R3. The lowest average oxygen values, namely 3,2 mg.l-1 (2,0), were in pond R3 in 2016. Taking account of the adverse development of the essential parameters (oxygen and clarity deficits) and the status of the trophy certain limitation of the farming intensity was proposed, namely: reducing the carp stock down to 1/3 including a calculation of the production-related financial loss. Reducing the stock is the only way how to make the fish ponds sustainable. Relevant compensation, in line with the effective European regulations, needs to be addressed hand in hand with the proposed measures.

Applying geographically weighted regression in regional development
ŠINDLER, Milan
This thesis deals with the modelling of applying techniques of ordinary least squares method and geographically weighted regression for all administrative divisions of the Czech Republic using ArcGIS software. In general this thesis introduces a GWR method which partially solves the problems associated with the analysis of spatial data. The research compares benefits of using geographically weighted regression with spatial data compared with linear regression in thesis conclusion.

Effectivity of strategies for data backup
Šindler, Martin ; Ležák, Petr (referee) ; Burda, Karel (advisor)
This bachelor´s project is focused on efficiency of backups using mathematical models, which calculates overall capacity needed for backup and capacity required for complete recovery, it also compares availability of rotation schemes. Models are based on propability of data change in certain time interval specified as backup cycle. Models are implemented to the application, which can be used for choosing the best rotation scheme.

The impact of zooplankton on carp production in Bohelov ponds
ŠINDLER, Martin
Zooplankton dynamics and the changing parameters of pond water in Bohelov ponds was monitored by regular sampling of zooplankton at approximately weekly intervals from April to October 2014 with sampling Schlott-Bauer method in a volume of 20 and 60 liters. The samples were divided into taxonomic groups and species, classified in so-called filterable zooplankton over 500 m. From the pond water parameters was monitored oxygen, pH, temperature, transparency and acid neutralizing capacity and their impact on production in ponds. Control fish out in each month showed a direct correlation with the increase in biomass Common carp (Cyprinus carpio) on the abundance of filterable zooplankton comparing the pond no. 1 and 3. Stocking was fed with feed wheat (Triticum) during the season. The abundance of zooplankton was different in different ponds and gradually changed by increasing fish stocking. A greater abundance of filterable zooplankton of Daphnia - Cladocera and lower species was noticed in the pond no. 1 as in the pond no. 3. With the increasing biomass of fish stocking has been demonstrated reduced of filtrable zooplankton where the number of small zooplankton (< 500 m) ind.l-1. Zooplankton was represented particularly by species Bosmina longirostris, Chydorus sphaericus, Daphnia galeata, D. parvula, D. ambigua. In order copepods - Copepoda were seen mainly nauplius and copepod stages of type Acanthocyclops americanus, rotifers were represented mainly by Brachionus sp. and Polyartha sp.. Increased abundance of filterable zooplankton has a impact on the final amount of biomass of fish stocking expressed by growth SGR (% .day-1) and a reduction coefficient relative FCR. Due to intensive farming combined with farming of poultry during the last decades has been observated accelerated eutrophication process of reducing the size of the littoral zone with a share of macrophytes.
