Napjatostně deformační analýza mostu v Třineckých železárnách
Ščerba, Bořek ; Skalka, Petr (referee) ; Fuis, Vladimír (advisor)
The bachelor thesis analyses stress and deformation of the truss construction. The first point of the thesis is a research, which includes obtaining information about the construction, for exemple dimensions, loads, purpose, history etc. Then, calculation models are created considering a different level of simplification. Two analytical models are crutial for the thesis – one statically determinate and the other statically indeterminate. They are used for analysing two different loads applied to the construction using methods of solid mechanics – it’s own weight and its own weight in combination with a weight of a vehicle that is driving through. Afterwards, the statically inderteminate model is verified using finite element method (FEM).

Napjatostně deformační analýza rozhledny Hraniční vrch
Novák, Tomáš ; Skalka, Petr (referee) ; Fuis, Vladimír (advisor)
Bachelor thesis is focused on stress and deformation analysis of strut frame, which is based on lookout tower Hraniční vrch by the city Město Albrechtice. The main goal is to create simplified 3D model and his resulting analysis at various degree of static indeterminateness. The first part contains introduction to history of lookout tower, theoretical introduction to bar, strut frame and limit state, followed by calculation of three various static indeterminate level. In the last part is verification of analytic results by numeric method. Another goal is to create thesis, which will also give a guidence for future solver of more complex 3D strut frame.

Stretch metal
Dostál, Jan ; Pangrácová, Lucie (referee) ; Gabriel, Michal (advisor)
Controlled deformation. Under with conditions can the iron deformation process be affected? This work is focused on expanding steel profiles. Using various tests, I will confront the visual results with the technical possibilities of the material. Attempting to find a boundary that is still permissible in terms of maximum steel loading just before the material starts to fail. The resulting installation should show the enormous forces needed to distort the material, where the viewer will be directly confront with the process.

Tribune of football stadium
Weber, Jozef ; Kostiha, Vojtěch (referee) ; Švaříčková, Ivana (advisor)
The aim of the diploma thesis was to design the precast reinforced concrete prefabricated structures of the football tribune. It was modernized sports center in Brno. According to the investor was determined the shape of the football tribune. It was compiled the design documentation. For the calculation of inner strengths was used the software Dlubal RFEM, which operates on the Finite Element Method - FEM. All elements have been designed for ultimate and serviceability limit state. My thesis contains textual part, inner strengths, static calculations, drawing documentation of composition of structure, drawing documentation of reinforcement and design documentation of the object.

Stress and deformation analysis of railway bridge over the Svratka River
Kovář, Jaroslav ; Žák, Stanislav (referee) ; Fuis, Vladimír (advisor)
This thesis deals with stress and strain analysis of real truss bridge structure. This structure is modelled as plane bar system. The opening part dedicates to theory, which is further used for calculations. The calculation part dedicates to compare statically determinate and indeterminate variation of structure for load by own weight and passage of the train. Analytic calculations are numerically verified with program ANSYS. In thesis is assessed concentration of stress, when the rivet drops out of the structure. The next part of thesis dedicates the spatial model of bridge, which is compared witch plane model.

The Shortest Graph's Pahts Finding
Jágr, Petr ; Ohlídal, Miloš (referee) ; Jaroš, Jiří (advisor)
The aim of this thesis is finding, comparing and implementation of algorithms for finding the shortest paths between each of pairs of nodes in a graph. For this task I use modifications of existing algorithms to achive the lowest time consumption of the computation. Modifications are established on Dijkstra's and Floyd-Warshall's algorithm. We also familiarize with Bellman-Ford algorithm.

Chess Server
Bárczi, Viktor ; Trchalík, Roman (referee) ; Jirák, Ota (advisor)
This work deals with the creating, and solving the problem of a chess server. It is about creating a chess server wherewith people can play chess through the Internet or a local network and also on a PC. In the real world the construction of the informational system resembles chess games between two players. According to the basic rules of chess the control of the right movements, the analysis of special movements like taking a figure and also rooking, projection and the analysis of checks and mates on the king are solved. During the game statistics of the movements are kept and after the end of the game the performance of the players are calculated by the virtue of record and statistics are kept about the gained ELO (rating) points.

The influence of the outdoor temperature on the properties of the reinforced layer in the implementation of ETICS
Novotný, Michal ; Gašparik,, Jozef (referee) ; Schmid, Pavel (referee) ; Sedlák,, Petr (referee) ; Lízal, Petr (advisor)
The trend in today's civil engineering are growing demands for quality and comfort constructed buildings and spaces in them. This trend causes a change in the approach to designing buildings and building new buildings. One of the main directions great importance is attached dedicated reconstruction of buildings and their technical adjustments to meet the ever increasing demands being norms and laws. One of the most monitored parameters are thermal-technical characteristics of objects - i.e. better quality means saving on heating costs. In this connection there is a big trend of the modern construction industry and building insulation, mainly ETICS systems. Dissertation focuses on the basic (reinforced) layer of the ETICS and examines the effect of low temperatures, acting on the matter in the implementation of the system, the properties of this layer. This coating is one of the key elements of the system, which more or less determines the quality and durability of the system. The first part deals with the current state of the problem and generally insulation systems, basic types and the advantages and disadvantages of these systems. In the main part of the work is solution focused work, its objectives and methodology for testing materials using laboratory tests and are mentioned outputs of experiments in terms of results. The final section addresses the evaluation of the data and results and output for construction practice. The theme of work was also addressed in the specific research. The works are also numerical and graphical attachments to records of experiments and calculations.

Transtibial prosthesis for recreational swimming
Křemen, Jan ; Mazůrek, Ivan (referee) ; Paloušek, David (advisor)
This thesis deals with the construction of an active transtibial prosthesis for recreational swimming. Its aim is to create a working sample of such a prosthesis. The device will primarily serve the patient to move in water - it will be attached to the stump and it will be driven forward. Secondarily, the prosthesis can be used for walking, in the sense that the patient attaches the prosthesis near to a water surface (pool, lake, ocean) and comes with it to the shore. As part of the design and electronics it will be necessary to determine the characteristics of the human resistance in water depending on speed and to determine the necessary propulsion (thrust) strength of the propeller, which will serve as the driving force. Subsequently there will be formed structural variants and selected the best one. This will become default for design and construction of simplified testing device, which will be tested for static thrust. After verifying the functionality and reliability, the final functional sample will be manufactured and tested too.
