    Direct georeferencing with correction of map projection distortions for active imaging

    Get PDF
    In aerial photogrammetry, the Cartesian coordinate system for the description of object space is commonly used. In contrast, many projects have to be processed in the space combined by the composition of a map projection and Vertical datum. In that space, some geometric deformations exist. There are some compensative methods for active and passive sensors. In the case of active sensors, decomposition and the correction of observation vector for each ground point can be used. We obtain height, horizontal distance and horizontal angle in this process. All of these values should be corrected for precise georeferencing. The contribution deals with the derivation of the corrections and gets some theoretical values from the area of the Czech Republic

    We report the publication of 953 DNA barcodes of forest leaf litter beetles from central Taiwan, in total representing 334 spe- cies of 36 beetle families. This is the first bulk of data from the Taiwanese Leaf Litter beetles project focused on uncovering the under-explored diversity of leaf litter beetles across Taiwan. Based on these data, we provide the first records of the following taxa for Taiwan: family Sphindidae (genus Aspidiphorus Ziegler, 1821); tribes Trichonychini, Ctenistini, and Bythinoplectini (all Staphylinidae: Pselaphinae); genera Gyrelon Hinton, 1942, Thyroderus Sharp, 1885, Cautomus Sharp, 1885 (all Cerylonidae), Dermatohomoeus Hlisnikovský, 1963 (Leiodidae), Paraploderus Herman, 1970 (Staphylinidae: Oxytelinae), Thinocharis Kraatz, 1859 (Staphylinidae: Paederinae), Cephennodes Reitter, 1884, Napoconnus Franz, 1957 (both Staphylinidae: Scydmaeninae), Bicava Belon, 1884 (Latridiidae), Otibazo Morimoto, 1961, Seleuca Pascoe, 1871 and Acallinus Morimoto, 1962 (all Curculioni- dae); species Oodes (Lachnocrepis) japonicus (Bates, 1873) (Carabidae: Licininae), Drusilla obliqua (Bernhauer, 1916) (Staphylin- idae: Aleocharinae) and Coccotrypes advena Blandford, 1894 (Curculionidae: Scolytinae). The records of Anapleus Horn, 1873 (Histeridae) and Batraxis Reitter, 1882 (Staphylinidae: Pselaphinae) have been confirmed. The male of Sivacrypticus taiwanicus Kaszab, 1964 (Archeocrypticidae) is described for the first time. Gyrelon jenpani Hu, Fikáček & Matsumoto, sp. nov. (Cerylon- idae) is described, illustrated, and compared with related species. DNA barcodes associated larvae of 42 species with adults, we are concisely illustrating some of these: Oodes japonicus, Perigona cf. nigriceps Dejean, 1831 (both Carabidae), Ptilodactyla sp. (Ptilodactylidae), Maltypus ryukyuanus Wittmer, 1970 (Cantharidae), Drusilla obliqua, Myrmecocephalus brevisulcus (Pace, 2008), Diochus sp., Mimopinophilus sp. (all Staphylinidae), Stelidota multiguttata Reitter, 1877, Lasiodites inaequalis (Grouvelle, 1914) (both Nitidulidae), Lagria scutellaris Pic, 1910, and Anaedus spinicornis Kaszab, 1973 (both Tenebrionidae). We also report the first cases of Rickettsia infections in Scydmaeninae and Pselaphinae. All data (sequences, metadata, and voucher photos) are made public in BOLD database and in a Zenodo Archive

V CAD programu je nakreslen příčný a podélný řez navrženého synchronního stroje.Katedra elektroenergetiky a ekologieObhájenoThis graduation thesis deals with electromagnetic design of a salient pole synchronous machine according to set parameters. The thesis is also focused on stator winding and finding possible number of parallel branch circuits. There are drawings of longitudinal and cross sections of the designed synchronous machine made in CAD

    Social agriculture as an alternative business solution for agriculture

    No full text
    This bachelor's thesis introduces social agriculture as an alternative business solution in the whole agricultural sector. This work is not focused just on social agriculture but also on agriculture in general and also on some social terms. It also explains the main meaning in social agriculture, its benefits in social life and for what kind of people it can be beneficial and helpful. It analyzes social agriculture in the Czech Republic and in other European countries.The literal research is divided into three parts. The first part is about agriculture in general and its main functions in agricultural sector. In the second part are described some social terms and the third part which is the longest one is about the social agriculture. The third part also deals with financing of farms or companies that concentrate on social agriculture in each country

The main attention is focused on the analysis of force load cutting edge with circle inserts from cutting ceramics (indexible inserts - Toshiba Tungaloy LX11) in relation to the median surface temperature of chips. For the measuring of the temperature the radiation pyrometer was used. The aim is to confront the results and determine the best cutting conditions in terms of cutting forces and temperatures for the turning of tool steel by cutting ceramic in the HSC regime
