Design of excavation and primary lining of the Dřevnovický tunnel at the construction of high-speed railway connection Brno - Přerov
Bastl, Jiří ; ING, Tomáš Zítko, CEng MICE, EUR (referee) ; Horák, Vladislav (advisor)
This master thesis deals with a design of a Drevnovice tunnel primary lining at planned high speed rail corridor connecting Brno and Přerov. The whole design as well as defining of the most suitable tunnel excavation method are described. Thesis also contains a breakdown of the excavation, construction technology and the scheduling of geotechnical monitoring procedures. The Plaxis 2D program, based on the finite element method, was used to create numerical models of two cross sections of the Dřevnovice tunnel. Based on mathematical modeling outputs, a static calculation of the primary lining was calculated.
Optimization of projection activities in EPLAN ELECTRIC P8 software
Obšil, Martin ; Bastl, Jiří (referee) ; Polsterová, Helena (advisor)
The thesis deals with the optimization of project activities in the software EPLAN Electric P8. First part introduces electrotechnical software EPLAN, the basic functions, and explains the methodology of the work in the program environment. This is followed by an analysis of the state of the electrical documentation of the TAC 75 circular saw manufactured by Exactcut s. r. o., and the method of designing. The thesis is also focused on the individual problems that make barriers between the average and the high quality level of design and the ability to use the available features of the purchased software. Thereafter, individual optimization steps and partial methods of reaching aims are described. Part of the thesis is devoted to finding solutions for interconnection of two engineering branches, which are electric and fluid technologies and in the end are revealed expansion modules of software, which can be used to achieve a higher level of professional planning activity.
Design of shallow foundation using Penetration tests
Bastl, Jiří ; Fiala, Radek (referee) ; Štefaňák, Jan (advisor)
The bachelor´s thesis focuses on the principle and implementation of penetration tests and search procedures using the test results of penetration test for design of shallow foundations. The purpose of this work is to compare the design of sallow foundations using conventional methods and computational methods based on the use of penetration tests. In the project TA04031092 – interpretation and correlation of dynamic and static penetration test, I worked with data on which I assembled and tested correlations between cohesion of clays and penetration resistance for the region and around Brno.
3D shape from camera pair
Bastl, Jiří ; Horák, Karel (referee) ; Richter, Miloslav (advisor)
The aim of this bachelor thesis is to create methods for obtaining 3D data from 2D images. This data will be used as an input data for algorithms which will process them into data formats creating 3D perception. In this work problem of rectification when we compare one image according to the other is solved as well as the problem of calculation of the model of a scene scanned with two cameras.
Online 3D reconstruction
Bastl, Jiří ; Horák, Karel (referee) ; Petyovský, Petr (advisor)
This thesis describes reconstruction of scene which is scan trough two cameras. There are described methods of calibration of cameras system, methods for finding the corners and methods for finding correspondences. Corners are searched by FAST detector and for search correspondences are used normalized cross correlation. In the framework of 3D reconstruction is implemented rectification. The final shape is saved to VRML format. In the thesis are described parallelization options. The calculation of the correlation is optimized for multiprocessors CPU and there are designed implementations of algorithm to GPU and FPGA too.
Analysis and comparison of numerical marking of steel according to ČSN, EN and ISO
This thesis deals with classification and designation of steel. It analyses current and most widely used systems of steel designation in EU - in connection with standards that are adapted and used in different branches and concerns in the Czech Republic. The preamble describes classification of steel. The most extensive middle part analyses typical methods of steels designation. The final part conducts comparison of above mentioned methods.
