Measuring of the Vertical gravity gradient at the locality TS-73 "Polom", Trutnov - Babí
Pešek, Michal ; Weigel, Josef (referee) ; Pospíšil, Lubomil (advisor)
This master´s thesis deals with the determination of vertical gravity gradient in the shaft below the infantry bunker TS - 73 "Polom" located in village Babí. After performing position, elevation and gravity measurements detailed points, representing the two vertical profiles were calculated gravity, vertical gravity gradient, block densities ang gravity anomalies depending on the depth. Other outputs work as a topographic map and a map of full Bouguer anomalies for the wider area of the location and interpretive geologic profile.

Documentation of Skalní zámek passage in Býčí skála cave - northern part
Langar, Tomáš ; Weigel, Josef (referee) ; Kratochvíl, Radim (advisor)
My bachelor thesis deals with speological mapping parts of cave system Býčí skála - Skalní zámek. Detailed measurements of plan view map are carried out with electronic method –through combination of measuring equipment DistaX2 and software application TopoDroid per the appropriate tablet. The resulting map is formed in the program Therion. The course of my bachelor thesis involves handling of apparatus and the instruction how to measure then process the data. The introductory part is devoted to the localization and extent of the thesis. The instructions of used surveying and software device are described in the subsequent parts. The final section is related to comparisons of mining suspension compasses.

ESP/ESC Impact to Behavior of Vehicle
Weigel, Filip ; Mrázek, Vojtěch (referee) ; Strnadel, Josef (advisor)
This bachelor thesis focuses on active safety - ESP. System ESP greatly improves stability of vehicle while turning. The thesis analyses modelling, brake functionality, subordinate systems of ESP - ABS and ASR, physical forces and phenomenons, model example, analysis of problem, design of model, implementation of model and experiments evaluation of implemented model in UPPAAL enviroment. The goal of the thesis is to prove that ESP system helps to stabilize vehicle while turning by simulation of vehicle model. Results are presented in well-aranged graphs side-by-side. It is possible to analyze the behaviour of vehicle while turning with ESP or without ESP.

Thematical map creation in locality V zrcadlech - southern part
Chalupková, Klára ; Weigel, Josef (referee) ; Kratochvíl, Radim (advisor)
The intention of the bachelor’s thesis is geodetic survey of former mining sites V zrcadlech and creation thematic map of area of interest at a scale of 1:500 and according to ČSN 01 3410 Maps of large scales. Base and thematical maps. The first part of the thesis deals with the preparation and surveying of the site. The second part deals with the office work, both data processing, as well as creation of the thematic maps. There was built survey net of auxiliary survey points on the site, which was determined by polygonal traverse and three-tripod equipment system using a total station. Connection of the traverse was carried out on horizontal control and points measured using GNSS. Points of detailed survey were measured from auxiliary survey points. The computational work was made in software Groma v. 7.0 and the graphic work was made in software MicroStation PowerDraft V8i and Atlas DMT.

GNSS deformation measurement in the Sněžník Network
Sobek, Josef ; Weigel, Josef (referee) ; Švábenský, Otakar (advisor)
This thesis deals with a processing and evaluation of GNSS data measured during the years 2001 - 2012 in geodynamical network Sněžník. The aim of the thesis is a detection of possible horizontal and vertical displacements of points in this network. The thesis also deals with comparison of results determined by only GPS and both GPS and GLONASS measurements. Graphic interpretation of displacements’ evolution during the whole monitored period is one of the results of this thesis.

Gravity measurements at Tetčice polygon
Bitalová, Katarína ; Weigel, Josef (referee) ; Pospíšil, Lubomil (advisor)
This master's thesis deals with measurements of highs and gravity of points polygon located in village Tetčice, through which is crossing a eastern fault of Boskovice furrow. With repeated measurement should be proved effect to high levels of groundwater. Repeated measurements are realized in the range 2 stages. In thesis is in detail described calculation complete Bouguer gravity anomaly and their quantitative interpretation. From the gravimetric of dates is created map of complete Bouguer gravity anomaly and interpretative profile through Boskovice furrow. Interpretative profile has localized fault, whose tectonic activity belong to possible factors level movement in the village. Level measurements meets the requirement of precise levelling. The results of the measurements are compared and discussed with the previous stages of the research.

Vertical Displacement Measurements at Brno Zábrdovice Church
Bocková, Lenka ; Kratochvíl, Radim (referee) ; Weigel, Josef (advisor)
The diploma thesis deals with measuring height new stage of the church network in Brno Zabrdovice. Measuring by using method of precise leveling be going on with previous stage began in 2002, in order to detect vertical displacement. Processing include calculation and adjust of the heights, compare with fundamental and previous stage, interpretation and graphical form of vertical displacement. The thesis includes measuring and processing angular deflection of church towers.

The Using of GNSS Permanent Networks for Height Determination
Kuruc, Michal ; Sokol,, Štefan (referee) ; Kostelecký,, Jan (referee) ; Vatrt, Viliam (referee) ; Weigel, Josef (advisor)
This Thesis deals with the evaluation of height accuracy of GNSS point positioning. Many experimental measurements aimed on GNSS and heights issues was realised within this work. The ellipsoidal heights were measured together with the orthometric heights and then the local Quasigeoid model was created. The network of height points was built to realisation of proposed measurements on the territory of the city Brno. The model of Quasigeoid from experimental measurement was compared with any other models of Quasigeoid and with local astronomical model. The partial aim of this Thesis is the proposal of methodology of height determination by GNSS technology and levelling measurement together. We can determine or verify the orthometric heights by using GNSS measurement and this methodology.

Analysis of selected variations of the gravity due to the mass dynamics
Volařík, Tomáš ; Lederer,, Martin (referee) ; Vatrt, Viliam (referee) ; Mojzeš,, Marcel (referee) ; Weigel, Josef (advisor)
This dissertation is focused on a study of selected environmental effects influencing terrestrial gravity observations. Global geopotential models were used to compute quantities of the disturbing gravity field and its variations during time period. Furthermore, analyses of an atmospherical and hydrological effects on the gravity observations were provided. The computation was realized at the station Pecný, however the concept was proved and compared with data from station Strasbourg. Consequently, the results were discussed with respect to quasigeoid modelling established from gravity and astrogeodetic measurements. The result and recommendations for future research are exposed.
