Blender Plugin for Conversion of Models to Vector Graphic
Kopáček, Jiří ; Chlubna, Tomáš (referee) ; Milet, Tomáš (advisor)
This thesis deals with the design and implementation of several extensions for an existing module (plugin) for Blender software. This plugin could be used for conversion of 3D models in a Blender scene to a 2D vector graphics file in the SVG format. New extensions include the support of curve, text, Grease Pencil or annotation conversions and their depth sorting, as well as support of collection sorting, using camera objects and creating animations. Improvements of existing parts include a complete user interface rework, improving capabilities with a new material system and several fixes to existing code. The result of the implementation is a new version of the plugin which allows the user to efficiently create more complex vector graphics in Blender with enhanced output styling options.
Groundwater Influence of Streamflow Quality in Crystalline Areas under Easing Acid Deposition
Erbanová, Lucie ; Hrkal, Zbyněk (advisor) ; Navrátil, Tomáš (referee) ; Kopáček, Jiří (referee)
Surface waters from crystalline areas are a significant easily accessible source of drinking water. However, these areas often experienced high loads of acids from atmospheric deposition over the last century. Degradation of soils and surface waters occurred subsequently, especially in areas built of rocks vulnerable to acidification. The main objectives were to quantify the role that groundwaters play during streamflow generation and to evaluate the rate that groundwaters control stream water chemistry. The present-day quality of groundwaters and surface waters was compared with the quality at the period of easing atmospheric deposition. Groundwater brings base cations released by bedrock weathering into streamflow enhancing streamwater alkalinity at all flow levels. During baseflow conditions, streamflow was predominantly supplied with groundwater from deeper fractured bedrock. However, groundwater runoff is supplemented by water from shallower catchment reservoirs (shallower fractured bedrock, soils and overland flow). Thus, the chemistry of baseflow is not as invariable as usually considered. The acid neutralizing capacity (ANC) of stream water was correlated with the amount of more acid waters. To the contrary, the pH of streamflow was stable during baseflow conditions. Alkaline groundwaters...
Blender Plugin for Conversion of Models to Vector Graphic
Kopáček, Jiří ; Chlubna, Tomáš (referee) ; Milet, Tomáš (advisor)
This thesis deals with the design and implementation of an extension (plugin) for Blender software. This extensions adds the feature of converting 3D models in a Blender scene to a 2D vector graphics file in the SVG format that represents the original scene. The thesis focuses on creating the plugin's user interface, conversion of vertex coordinates from 3D scene to 2D window coordinates, calculating the resulting polygon color based on lighting and material, cutting of conflicting (colliding) objects and determining the order in which the resulting polygons have to be drawn. The result of the implementation is a plugin that allows the user to create 3D models which can be converted (snapshot) to SVG formatted vector graphics files, instead of manually creating 2D vector images.
Prediction of phosphorus concentration and trophic conditions in reservoirs
Hejzlar, Josef ; Kopáček, Jiří ; Vystavna, Yuliya
The model prediction of phosphorus (P) concentration in reservoirs is important for controlling water quality and trophic conditions, e.g. to determine to what level external P load should be reduced in order to decrease trophic conditions and achieve good ecological potential. The mass balance of P for 26 reservoirs and lakes in the Czech Republic showed that the relationship between the inflow P concentration and the in-reservoir P concentration is not determined solely by hydrological parameters (water residence time or hydraulic load) or inflow P concentration but is fundamentally influenced by the internal P loading from sediments and in-reservoir P cycling. These are individual characteristics of each reservoir and may change, for example with sediment accumulation or changes in external P load. Therefore, the prediction models need to be assembled and calibrated for each reservoir individually and the model structure should be adapted to their specific conditions.

Phosphorus concentration in the Orlík and Slapy reservoirs: a result of socio-economic trends in the catchment and climate change
Hejzlar, Josef ; Jarošík, Jiří ; Kopáček, Jiří ; Vystavna, Yuliya
Based on existing phosphorus data series in the Slapy and Orlík reservoirs and their main tributaries, we reconstructed P inputs to the reservoirs from the catchment during 1961–2016 and compiled\nempirical models of P retention. P concentrations in both reservoirs increased from the 1960s to 1991 and then declined, with the Slapy Reservoir having a significantly increased year-on-year\nvariability. Trends in the increase and decrease of P reflected the socio-economic development in the Vltava river basin, in particular sewerage, wastewater discharges, fertilizer application, livestock,\nand fishpond fisheries. In the Slapy reservoir after 1991, the P concentrations increased during wet summers and created conditions for growth of phytoplankton, whereas in dry summers they\ndecreased to mesotrophy. Climatic and hydrological processes have now apparently begun to compete with a generally decreasing P pollution and support eutrophication despite the drop in P loads from the catchment.
Provisions of Czech republic to reduction of incidence fo crisis on Czech republic
Kopáček, Jiří ; Mirvald, Michal (advisor) ; Bartoň, Petr (referee)
The aim of my bachelor thesis is to analyse anti-crisis provisions of National economic council of government (NERV). I confront the provisions with reality and try to find out, if the provisions are effective or not for now. Proposed provisions, which I devote in the thesis are concerned in changes in payment of insurance of employee and tax liability of firms. The thesis is devided into three main parts. In the first part I shortly devote to causes of financial and economic crisis and consequent establishment of government advisory authority -- NERV. Main topic in this part is change in payment of insurance of employee. To find out of effect of these provisions I use correlation analysis. In the second part I am engaged in change of tax rate of corporation tax. I use theories of economists of supply side (Arthur Laffer). The biggest attention I pay to Laffer curve, which I demonstrate for Czech republic. Final third part of thesis represents effect thereinbefore mentioned provisions on employment in CR, which I then compare with employment in EU.
