Lagomorpha (Mammalia) of the Pliocene and Pleistocene of Europe: a revision of selected taxa
Čermák, Stanislav ; Horáček, Ivan (advisor) ; Sabol, Martin (referee) ; Benda, Petr (referee)
1 Lagomorpha (Mammalia) pliocénu a pleistocénu Evropy: revize vybraných taxonů Stanislav Čermák Předkládaná dizertační (uznaná jako rigorózní) práce se zabývá vybranými taxony fosilních zajícovců (starobylá konzervativní skupina býložravých savců) úseku spodního pliocénu až spodního pleistocénu (ruscin - bihar) Evropy. Technikami podrobné morfometrické analýzy (42 metrických, 14 nemetrických znaků) byl zpracován fosilní materiál (většinou nový nepublikovaný) dentálních a kraniálních pozůstatků rodů Psedobellatona, Ochotonoma, Ochotona a Hypolagus (N = 639) celkem z 38 lokalit území Česka, Slovenska, Maďarska a Ukrajiny reprezentující stratigrafický úsek spodní ruscin až svrchní bihar (MN 14 - Q2). Daná práce podává: (1) Ochotonidae - detailní revizi dosud komplexně nestudovaných taxonů pišťuch "skupiny Ochotona" spodního pliocénu (ruscin) východní a jihovýchodní Evropy (tj. taxonů Ochotona antiqua, Pseudobellatona, a Ochotonoma); v kontextu Česka a Slovenska revizi nálezů rodu Ochotona z pleistocénních (MN 17 - Q1) lokalit daného území, která podstatnou měrou rozšiřuje znalosti o těchto pišťuchách založené dosud na relativně nepočetných nálezech z lokalit Francie, Německa, Polska a Maďarska; (2) Leporidae - komplexní revizi rodu Hypolagus - stěžejního a dominantního rodu čeledi Leporidae pliocénu a...
Concept of species in bears (Ursidae): practical, historical, and theoretical viewpoint
Wagner, Jan ; Fejfar, Oldřich (advisor) ; Sabol, Martin (referee) ; Musil, Rudolf (referee)
The present thesis surveys topic of taxonomic diversity and phylogeny of bears (Mammalia, Ursidae) and aspects of its contextual setting under effects of changing conceptual and methodological viewpoints. This problem is studied from several perspectives. The historical perspective is represented by a critical overview of the history of specific and infraspecific classification of bears with special respect to mutual influences of this classification and theoretical concepts of species accepted in particular periods. The perspective of material approach is exemplified by a material-based study of taxonomical and phyletic status of selected Pliocene to Middle Pleistocene ursine taxa. Along with deconstruction of some traditional hypotheses this produced a model explaining species diversification in ursine bears and its discussion in terms of factual relevance of included background concepts. In the pre-evolutionary period the bear species were usually understood broadly, as incipient immanent entities, yet exhibiting obvious certain infraspecific variability. This was established using definitions of varieties (mostly not identifiable with present subspecies or infraspecific taxa) considered as unstable modes of particular species. Although, in the post-Darwinian period, the concept and taxonomic...
FM Transmitter of APRS Telemetry in 144MHz Band
Sabol, Martin ; Špaček, Jiří (referee) ; Urbanec, Tomáš (advisor)
This work deals with analysis of protocol APRS Automatic Positioning System for telemetry. There is analyzed the structure of the most important frames and their application. It discusses the processing of GPS data and subsequent modulation of the selected frequency. This work also describes and discusses the proposed peripheral devices and the used firmware.
Realization of Measurement System for Analogue Values with Memory
Sabol, Martin ; Dřínovský, Jiří (referee) ; Urbanec, Tomáš (advisor)
This bachelor's thesis deals with transfering analogue values to digital form. Measuring values are saved with the information about time of measurement into the memory and these are ready to processing in PC. The Measurement system is composited from the main digital circuit, which is connected to measuring channel. Whole designed circuit with program equipment is exactly described in this work.
