Testing of precision of construction lasers
Absolonová, Jana ; Foral, Jakub (referee) ; Machotka, Radovan (advisor)
This Bachelor´s thesis deals with accuracy testing of chosen building laser tools. At first, features of these devices are described. Then the measurement procedure is explained. By this measurement the values for the calculation of errors are obtained. These errors are compared with the maximum deviations prescribed in the manual by the manufacturer. In conclusion, the practical applicability of selected devices is described in relation to measurement experiences. All measured values, calculations and charts are located in attachments of this thesis.

New sensors of distributed control system in medieval Jeroným Mine in Čistá
Kaláb, Zdeněk ; Knejzlík, Jaromír
Addition of instrumentations of distributed control and measurement network for geomechanical measurement is performed subsequently. Measurement of crack development in the mine working, development in changes in convergence cross-sections of linear workings and fluctuations of water levels in underground spaces was initial parts of this network. At present, measurement of convergence in chamber (spatial working) using laser distance meter, measurements of changes of tensor stress state of rock mass and measurements of temperature of mine atmosphere completed the network.
