Biomechanical study of the proximal part of the femoral intermedullary nail
Hrdlička, Jan ; Valášek, Jiří (referee) ; Florian, Zdeněk (advisor)
The presented Master Thesis is focused on the structural analysis of the proximal femur on which the Proximal Femoral Nail (PFN) and Proximal Femoral Tele-Screw (PFT) systems are applied. These systems are used for a treatment of the intertrochanteric and femoral neck fractures. However, in some cases a loss of stability of the systems may be expected. The presented thesis describes a development of numerical models in which stress distribution of implants and strain distribution of bone tissue are compared. Numerical models were created from real objects. The model of femur geometry was created by using the Computed Tomography (CT). Boundary conditions of the model were estimated from the force equilibrium of the lower limb. All numerical models were processed in the commercial package ANSYS Workbench v15.0. It is shown that the hip screws of the PFN system result in lower equivalent stresses than the screws of the PFT system. Maximal strains of the bone tissue, when using the PFN system, are situated near the fracture, close the hip screw thread. For the PFT system, the maximal strains are only near the area of fracture.

Biomechanics of fixation of proximal femur
Hrdlička, Jan ; Marcián, Petr (referee) ; Florian, Zdeněk (advisor)
In this bachelor thesis, issues of treating fractures of femur are solved, especially fractures of proximal parts of femur. Several ways of treatment, for example plates, intramedullary nails, fixing cable and external fixation are described here.Basic anatomical terms, including construction of long bones are also presented. There is a calculation of a strength load of femur. According to the calculated strength load, a computional model of final elements with a program called Ansys was completed. The model is created with a short reconstruction nail.

Prices of Construction Works in Reconstructions of Existing Construction Objects
Hrdlička, Jan ; Vítková, Eva (referee) ; Puchýř, Bohumil (advisor)
In the teoretical part of the thesis, i would like to explain the recontructions of historical building problém, the issues of valuation and calculation formulas. I will briefly outline the general provision of law no 134/2016. The public procurement act and the selection procedure of the tenderer In the practical part i will compar the differences between the two valution products, the general part and the valution part. At the selected tender, i will show how the selection proces is taking place in our company. In the end, the there will be a comparison between the variant reconstruction solution and selection of a suitable solution for the recontruction.

Ladislav Smoljak, editor of the Mladý svět magazine
Hrdlička, Jan ; Slomek, Jaromír (advisor) ; Osvaldová, Barbora (referee)
This thesis deals with a not very well-known topic - it analyses the journalistic and publicist work of Ladislav Smoljak in the print media, especially in the magazine Mladý svět. It aims to reveal how Smoljak approached his work as a journalist, what were the specific features of his work, with what topics he dealt, and to what extent he contributed to the image of the magazine. I also include an article bibliography of Ladislav Smoljak during his time at the editorial office of Mladý svět. In the theoretical part, I present Smoljak's biography together with an outline of the historical context and a description of the Czechoslovak media scene of the time. The practical part then analyses Smoljak's texts and assesses his role in the magazine.

One about the other one: What Čapek brothers published about each other
Hrdlička, Jan ; Slomek, Jaromír (advisor) ; Osvaldová, Barbora (referee)
This thesis is focused on a topic which, up to this point, has been mostly marginal. It pays attention to the mutual presentation of the Čapek brothers during the so-called First Republic. It aims to reveal the means they used to write about each other in the press then and what were the features and circumstances of those references. It also deals with the self- presentation of the Čapek brothers as a duo. I intend to present the relationship between Karel Čapek and Josef Čapek to the current recipient just like it could have been seen by people in former Czechoslovakia. The theoretical part explains primarily the life of both authors and their position in a world back then, but also the situation of media during the First Republic. The practical part then analyzes the mutual references and it deduces the relationship brothers had in a Czechoslovakian press.

Pseudo-differential frequency filters
Hrdlička, Jan ; Herencsár, Norbert (referee) ; Koton, Jaroslav (advisor)
This Bachelor thesis deals with the pseudo differential frequency filters. Introduction The thesis describes the characteristics and frequency filters. The following describes the active elements, especially the differential current conveyors. The main objective is to design pseudodiferentialfrequency filters using the transformation nondifferential structures using differential structure differential current conveyors.

Srovnání stability evropských bank
Hrdlička, Jan
Hrdlička, J. Comparison of stability of European banks. Bachelor thesis. Brno: MENDELU, 2014. In this bachelor thesis, we are observing influences on the capital adequacy using the other indicators. Based on the hypothesis, we create the model, into which we will subsequently fill in other suitable variables.The aim is to get a sta-tistically significant model that meets the classical assumptions.
