Stereological analysis of ellipsoids
Hájek, Tadeáš ; Pawlas, Zbyněk (advisor) ; Beneš, Viktor (referee)
In this thesis local stereological estimators of parameters of ellipsoidal shaped particles in a plane and in a three dimensional space are investigated. The main attention is devoted to the local estimators of ellipsoid volume based on the knowledge of the section of the ellipsoid by a line, a plane or a plane which contains a fixed line. We investigate densities, mean values and variances of these estimators. In the end, for a special case of ellipsoid - spheroid, the accuracy of estimators is compared through the use of coefficient of error. Powered by TCPDF (www.tcpdf.org)

Petrogenesis and emplacement of post-collisional granitoids of southeastern Moldanubian Batholith
Hájek, Tadeáš ; Verner, Kryštof (advisor) ; Houzar, Stanislav (referee)
The Weinsberg Composite Pluton, located in the southern part of the Moldanubian Batholith is a large intrusive body with complex internal fabrics, petrogenesis and emplacement processes. On the basis of geochemistry and zircon morphology classification the dominating lithology in the northeastern part of the pluton seems to be the second type of the Weinsberg granitoids (WbG II). Based on the integration of the structural, petrological and geochemical data set acquired from the investigated area, the interpretation of geodynamic evolution and emplacement of the eastern part of the Weinsberg Pluton could be proposed. This interpretation invokes: (a) indentation and underthrusting of a continental microplate (Brunia) in the east at around ~340-330 Ma, driving mantle delamination and subsequent heating and anatexis in the metapelitic lower crust as the heterogeneous source for Weinsberg- and Eisgarn-types of granitoids; (b) subsequent growth of a large metamorphic dome along the edge of the Brunia indentor followed by polyphase emplacement of entire eastern part of the Moldanubian Batholith around ~330-325 Ma including the Weinsberg Composite Pluton in the south; (c) increasing role of the N-S shortening and associated NW-SE dextral shearing along localized shear zones which caused the prevailing...

Petrogenesis and emplacement of the Weinsberg granitoids in Nove Hrady Mts. (Moldanubian Batholith]
Hájek, Tadeáš ; Verner, Kryštof (advisor) ; Špillar, Václav (referee)
(english) First part of this bachelor thesis contains a summary of existing knowledge of post- collisional magmatic activity in Bohemian massif with accent on genesis and construction of large intrusive complex - Moldanubian Batholit. Possible geodynamical aspects, petrogenetical and physical processes of genesis and emplacement of granitic magmas are further described. Practical part of this bachelor thesis is based on observation and documentation of fabrics and structures in Weinsberg granitoids at rock outpost situated in locality Sokolčí u Kaplice.

Statistical properties of local stereological estimators
Hájek, Tadeáš ; Pawlas, Zbyněk (advisor) ; Beneš, Viktor (referee)
In this thesis statistical properties of local stereological estimators of par- ticle volume are investigated. The emphasis is on the estimation of the va- riance of the local estimator and its components - the variance due to the variability in the particle size distribution and the variance due to the lo- cal stereological procedures. Various ways of estimation for independent and correlated particles are presented. Results of simulation studies for both inde- pendent and correlated ellipsoidal-shaped particles are presented. Described estimators are demonstrated on real biological data. Comprehensive theory that leads to the local stereological estimators of volume is presented too. 1
