Intersection Of Road III/01130 and Hillova st. In Opava Redevelopment
Škvainová, Aneta ; Klepáček, Josef (referee) ; Radimský, Michal (advisor)
The subject of my bachelor’s thesis is the redevelopement of the classical intersection of road III/01130 and Hillova street in Opava. The intersection redevelopement is solved in variants corresponding to the study. There are checked spatial options for adjusting the existing classical intersection to the roundabout. In the frame of variants, there is different possibility to solve a transformation of both pedestrians and cyclists traffic through the suggested intersection and a connection of current cul-de-sac street. Suggested parallel parking is the part of the final variant.

Evaluation of accuracy of shear formula for chosen shapes of beams
Bolcek, Jan ; Kořista, Milan (referee) ; Burša, Jiří (advisor)
This bachelor thesis pursues the judgement of accuracy of Jourawski’s formula in short beams. Assumptions, on which is Jourawski’s formula derived, are described in the theoretical part, there is also a procedure how to derive the formula. In the theoretical part is also stated a literature search on inaccuracies which are made by using Jourawski’s formula. The accuracy of Jourawski’s formula is judged by example of simply supported beam loaded with force in the middle and with cross section in the shape I. Firstly there is analytic calculation of distribution of shear stress which is then compared with calculation acquired by finite element method. By the finite element method are simulated three models of beams with different edge conditions, which are those derived from rod assumptions and the real ones. In the conclusion are compared and evaluated results from both types of calculations.

Location Study of Crossroad of Roads I/56 and II/469 in Hlučín
Škvainová, Aneta ; Cihlářová,, Denisa (referee) ; Radimský, Michal (advisor)
The subject of my Master’s thesis is the variant redevelopment of intersections I/56 and II/469 in Hlučín. Both interesections are situated nearby bus terminal. Extent of adjustment obstructs the object of former granary. There are checked spatial options for adjusting both existing intersections to the roundabouts. In the frame of variants, there is a different manner of solution of structural layout of both intersections, possibility of connection of bus terminal and transfer of pedestrian traffic across designed intersections. Part of Master’s thesis is traffic survey and capacity analysis of designed intersections.

Monitoring of Underground Construction with Low Overburden
Lossmann, Jaroslav ; Ožana,, Štěpán (referee) ; Hrubešová,, Eva (referee) ; Horák, Vladislav (advisor)
Geotechnical monitoring (GTM) is an essential part of the observation method. In the principle it is the measurement and monitoring of preselected magnitudes – their changing values in the course of the constructing process and their partial evaluation. On the measured values basis the correctness of designed structures and technological processes is verified, optionally new technical and organizational measures are adopted in order to guarantee the continuous and safe constructing course. The main goal of the dissertation is to analyze the current state of the problematics and evaluate the methods of GTM in underground structures with low overburden, including suggestions and recommendations for procedures. In the framework of knowledge, practical experience and data analysis, the basic types and procedures of monitoring elements of underground structures with low overburden will be defined.

Documentation of Barová cave - southwestern part
Zubík, Tomáš ; Kuruc, Michal (referee) ; Kratochvíl, Radim (advisor)
The bachelor thesis deals with the documentation of the southwestern part of Barová cave. The reader is familiar with the location and its peculiarities. Part of the thesis is a detailed description of the measuring work. The measurements were made using traverse, levelling and special speleological method of detailed survey with DistoX2 instrument. Field sketch is made on a tablet in TopoDroid program. The result of the work is the ground plan, transections and cross sections in the 1: 250 scale, the JTSK coordinate system and the Bpv height system.

Experimental and calculational salts' properties investigation for MSR reactors from nuclear data point-of-view
Burian, Jiří ; Ing. Miroslav Zeman, PhD., SÚJB RC Brno (referee) ; Katovský, Karel (advisor)
Nowadays there is research into molten salt reactors. The use of chlorine-based salts, which would be more available than known fluoride salts, is envisaged. The subject of research is not only the chemical and physical properties of chloride salts, but also their behavior in the neutron field and the influence of neutron balance inside the reactor. Many properties can also be determined using calculations that draw information from scientific nuclear libraries (endf). The purpose of this work is to compare important nuclear libraries with each other, and also to compare the reaction rates calculated from the library data with the reaction rates obtained by self-measurement. The preview will include a description of the necessary activities associated with the preparation of measurements, instructions for compiling the computer program NJOY and the process of the measurement itself. At the end of the work will be summarized the results and statements of which nuclear library is the closest in its values to the results of experiments.

Use of activation detectors for neutron field measurement in models of ADTS
Chudoba, Petr
Accelerator driven transmutation systems could be a solution to the problem with long-lived nuclear waste and opening the way to thorium fuel cycle. Due to intensive neutron source based on spallation reaction are these systems very litle dependent on the arrangement of the core and fuel quality. These systems can transmute the spent fuel, eventually 232Th or 238U without affecting maintenance of fission reaction. Additionally subcritical blanket ensures high safety. For these systems it is necessary to know the cross sections of reactions of fast neutrons produced in the spallation reaction with different materials. This data is necessary not only for the selection of appropriate construction materials, but also for creation of programs simulating accelerator driven transmutation systems. This thesis is focused on the experimental determination of cross sections of reactions 89Y(n,2n)88Y and 89Y(n,3n)87Y with neutron energies from 17,6 to 33,6 MeV. Yttrium is analyzed for its (n,xn) threshold reactions, which makes it appropriet activation detector for study of the neutron fields in model configurations of accelerator driven transmutation systems. The obtained cross sections are unique, in that so far there are no experimental data for used neutron energies. Powered by TCPDF (www.tcpdf.org)
