Dokoupil, Martin ; Chudý, Peter (referee) ; Kršek, Přemysl (advisor)
This thesis describes the way to create three-dimensional visualization of grass in computer graphic. Contains progress of grass visualization from past to present. Contains shader intro and its use for visualization. Text mention scene graph which has been used for implementation. Text describes three levels of detail and implemetation of waving grass. Text compares frame speed for each level of grass and frame speed for complete visualized grass.

Zhodnocení zdravotního stavu dřevin na vybraných plochách Obecních lesů Ostrov (okr. Ústí nad Orlicí)
Starý, Pavel
The bachelor thesis evaluates the health status of trees in the Ostrov Municipal Forests in the district of Ústí nad Orlicí. The monitoring was carried out from October 2021 to December 2022 using the field method in two areas. The hard-to-determine fungal pathogen species found were sampled for laboratory determination. A total of 11 fungal pathogens were found, with the most important species being pine blister blight (Lophodermium pinastri), spruce budworm (Armillaria ostoyae) and alder blight (Phytophthora alni). Among insect pests, the spruce budworm (Ips typografus) and the alder weevil (Agelestica alni) were detected on alders. The stands of the Ostrov Municipal Forest are in a satisfactory state of health despite the presence of these fungal pathogens and insects.

Porovnání shrnovačů píce Pöttinger TOP 342 a Krone Swadro TC 640
VOKÁČ, Martin
The diploma thesis is focused on the decision-making process when purchasing a new rake related to the size of the company. The decision process is between the machines Krone Swadro TC 640 and Pöttinger TOP 342. The work will compare factors related to surface performance, fuel consumption and economic aspects. The decision-making process will be simulated for five types of businesses with areas of 21.33, 100, 200, 500 and 2,000 hectares, from which the costs of 1 ton od materiál will be calculate.

Porovnání žacích strojů ŽTR Pelhřimov 164 a Krone R320
VOKÁČ, Martin
This bachelor´s thesis deals with a comparison of two selected mowers ŽTR Pelhřimov 164 and Krone EasyCut R320 designed for harvesting permanent grassland. The main factors that will be assessed in this work include the economic side, performance and fuel consumption. The comparison will be simulated on three types of farms with an area of 21,3, 170 and 1 700 hectares. The resulting costs associated with mowing will then be converted to 1 tonne of mass.

Porovnání senážních linek s řezačkami Claas a John Deere
VÁJA, Petr
This work will try to compare lines for forage harvesting for silage, in two farms with a focus on production focus and production method of harvesting. The main value will be calculated in performance, fuel consumption and financial costs of individual work operations. All costs will be converted to 1 tonne of mass. Samples and proven subsequent analysis of the components will be taken from the final product.

Monitoring rozšíření nekrózy jasanů (Hymenoscyphus fraxineus) v lesních porostech severní Moravy
Fuchs, Ladislav
This bachelor thesis deals with fungual pathogen H. fraxineus. This pathogen is spread troughout all Europe and attacks the ashes. There is no place in the Czech Republic where the ash will not be attacked. The work should help solve the problem called Hymenoscyphus fraxineus. The aim is investigate all the factors infuencing the intensity od infection in stands. In thesis has been found that most of abiotic growth factors have no effect on ash cultivation. The effect od the health of ash is positiveli reflected when the ash grown on natural habitats i fit has been naturally picked in the stand and is the as his mixed randomly

Vliv vlhkosti vzduchu a půdy na rozvoj vybraných patogenů řepky
Nečasová, Aneta
The thesis focuses on monitoring and appraisal of colza vegetation microclimate. Humidity and soil moisture were measured. It was monitored if colza was infested by selected pathogens which are related to humidity and soil moisture. Recorded figures were compared with figures recorded at a standard weather station situated near the monitored rape vegetation. Maps showing vertical stratification of humidity in whole vegetation profile were created. Using regressive analysis equations of relation between humidity in vegetation and at the weather station were created. It was found out that weather influences the pathogen development. It was proved that predication only by "petal test" is inaccurate, so it is good to do it together with the microclimate monitoring.

Monitoring mikroklimatu pšenice seté pro fytopatologické a fenologické účely
Konečná, Petra
In 2016, a microclimatic monitoring was established in the Žabčice area on the grounds of the School Farm Enterprise, located in winter wheat. Several aspects have been observed, especially relative humidity and air temperature in this stand. The measurements were made at three heights (ground floor, effective height and 2 meters above ground). Measured values of temperature and relative air humidity in winter wheat were recorded during phenological development and their course was then graphically evaluated. It has been confirmed that the structure of the crop affects its microclimate. Furthermore, the occurrence of leaf pathogens was monitored according to the methods of the UKZUZ, depending on changes in microclimate in the stand. Based on these observations, it is possible to predict pathogen attack.

Využití chladnokrevných koní v lesním hospodářství u LČR, s.p., LS Vsetín, na revíru Kychová
Kocurková, Daniela
This bachelor thesis solves and evaluates the use of heavy horses in skidding timber in the certain forest property among 2010–2018 years and it compares them with other methods of skidding operations used in forestry. Description of local conditions is the part of the thesis – especially natural conditions, which influence the operations associated with logging and transporting in the interested area importantly. The theoretical part explains the basic terms relate to solved issues. Data processing of the forest management plan and interviews with local foresters were primary for the practical part. The interviews with local coachmans were important too. It was found, the heavy horses participated 19.5% portion on the total skidding timber.

Posouzení rozdílů ve vnější stavbě půdních agregátů na lesních půdách v ČR vzhledem k jejich stabilitě ve vodním prostředí
Macháček, Vlastimil
This diploma thesis studies the external layers of water-stable aggregates found in different soil types. The selection of locations in which the soil samples were taken was dependent upon different soil types, economic interventions, and the age of forest vegetation. A total of twenty soil samples from the top mineral layer of soil were collected from five locations. The soil samples were subsequently tested for the stability of water-stable aggregates, and sent for a digital as well as grain size analysis. The tests revealed different values in the amount of surface area, aggregates volume, and contents of clay in soil. Water-stable aggregates found in the same soil type showed a similar trend in the amount of surface area and aggregates volume depending on the age of forest vegetation.
