Bone implants based on Fe
Bachmayer, Marek ; Vondrák, Jiří (referee) ; Sedlaříková, Marie (advisor)
This thesis deals with usage of metal materials in bone implats creation process. This work also includes information about structure and attributes of bones, body fluids and content of iron in human organism. Following part of the paper deals with osteosynthesis, therefore commonly used methods of treating bone defects. Next part of this bachelor’s thesis is discussing the issue of biomaterials, biocompatibility and biodegradability of metal materials. Sample preparion procedure and description of samples, electrochemical corrosion and microscopic observation is included altogether with a pictorial documentation at the last chapters of this paper.

Documentation of MTB Trails Malhostovice - Brno
Samek, Richard ; Soukup, František (referee) ; Vondrák, Jiří (advisor)
The aim of my bachelor thesis was to design and measure a several of MTB trails between Brno and Malhostovice and to compare their course with draw in tourist maps of different scales and editions. Measurement trails was done by means of tourist GPS. Directional and altitude profiles were created from the measurements. Afterwards, the tourist maps were transformed to digital form. Directional and altitude profiles were also created from the digital form. Result of this thesis is comparison of the profiles and evaluation whether used maps designed for MTB activities are suitable or not.

Thematic map of path and stream in Lubě valley under Paní hora hill
Pačinek, Erik ; Ježek, Jiří (referee) ; Vondrák, Jiří (advisor)
An auxiliary survey network was built in the locality and connected to the bindincg reference system S-JTSK and Bpv. The network was measured using GNSS technology and the polar method. From these designated points of the network, deatailed measurements were made by the tachymmetric method. Obtained values and data from the measurements were processed in relevant geodetic programs. The result of this thesis was to create a thematic map in scale 1: 500 with all necessary documentation. Outputs of the thesis were prepared for eventual handover to DMT creation.

The Freezing Point Determination Of Electrolytes With Fire Retardant By Cryoscopy Method
Štulák, Stanislav ; Vondrák, Jiří (referee) ; Máca, Josef (advisor)
The thesis is devoted to the field of properties investigation of new types of electrolytes, and assess the appropriateness of electrolytes studied in this paper for use in Li -ion batteries. It focuses specifically on electrolytes based on aprotic solvents and their mixtures with the flame retardants. The goal of the thesis is to investigate the effects of FRAs on electrolyte mixtures via changes in specific conductivity and freezing point. These objectives were fulfilled by using electrochemical impedance spectroscopy in combination with a cryoscopic measurement method. There were overall 16 samples examined. The samples were prepared as a combination of chemicals, specifically Ethylene carbonate (EC), propylene carbonate (PC), dimethyl carbonate (DMC), dimethyl sulfone (DMSO2), triethyl phosphate (TEP) Dimethyl methylphosphonate (DMMP), triphenyl phosphate (TPP). Based on the results of the experiments, the mixtures were sorted according to the observed properties in the tables listed in the last part of this paper. These values can be further used to supplement the continuing research of electrolytes and also as assistance in searching for the new electrolyte mixtures.

Surveying and creation of thematic large scale map in Brno area
Zajíčková, Katarína ; Brátová, Kateřina (referee) ; Vondrák, Jiří (advisor)
The object of this bachelor thesis was to measure and construct the thematic map in city of Brno, specifically in locality called Wilson forest. It was built auxiliary measuring network, which was by the public punctual field connected to the mandatory reference systems – S-JTSK and Bpv. Subsequently from auxiliary measuring spots, was by tachometric method measured a specified territory. Then the coordinates and the altitudes of measured spots have been calculated. Afterwards was made testing of exactness of checking measured spots and from measured data was made the thematic map in the map scale 1:500 and in the third grade of exactness.

3D model of the selected object
Jirásek, Michal ; Vondrák, Jiří (referee) ; Kalvoda, Petr (advisor)
Subject of diploma thesis is creation of a georeferenced 3D model of selected object by close-range photogrammetry. Part of the work is research of photogrammetric software’s and evaluation of accuracy of the model. Suggests a photogrammetric processing procedure in ContextCapture software. The resulting model was compared with a reference cloud of points determined by ground scanning.

Surveying of stream Lubě between Skalička and Malhostovice
Jirásek, Michal ; Volařík, Tomáš (referee) ; Vondrák, Jiří (advisor)
The aim of this bachelor thesis is planimetry and altimetry measuring tacheometric method part of valley Lubě stream and copy tacheometric plan in scale 1:500. Resultant tacheometric plan is connected to references geodetic systems S-JTSK and Bpv. Output of work was data ready to handover for create DMT at form edit triangulated network. Elaborate of tacheometric plan meets standards ČSN 01 3410 and ČSN 01 3411.

Surveying and creation of thematic map in Square 28. října in Brno
Pavlíček, Ondrej ; Machotková, Olga (referee) ; Vondrák, Jiří (advisor)
The bachelor thesis deals with obtaining planimetry and altimetry data by geodetical measuring of the 28th October Square in Brno city. The result will be a thematical map in scale 1: 500 in the 3rd accuracy class according to standard ČSN 01 3410 - Large Scale Maps, made in the S-JTSK coordinate system and Bpv height system. The task includes selection and terrain reconnaissance of the site, detailed measurement and processing of gathered data. The bachelor thesis will serve as a basis for project activity.

Observation of educational control framework in Björnson park in Brno
Andraško, Matúš ; Vondrák, Jiří (referee) ; Machotka, Radovan (advisor)
The bachelor work deals with control framework, which was made for education and training students VUT faculty of civil engineering in Brno. This point field was surveying by GNSS method, which was enough for its purpose. Our task was specify this control framework by combination of terestric and satellite methods. Documentation of this task involves tables of coordinates in positional system S-JTSK and altitudes in system Bpv and geodetic sketch of control framework.
