Simulation of Idiofonic System
Múčka, Martin ; Keršner, Zbyněk (referee) ; Frantík, Petr (advisor)
The thesis deals with dynamic simulation of real bell behavior over time. The model is created according to principles of physical discretization as a spring in the FyDiK3D software. In order for the model to be declared as relevant, it is necessary to prove the behavior of the structures used in the elementary tasks of the mechanics. It shows the correlation between the stiffness of normal and diagonal springs. Describes how to use software import tools to create a model. The resulting model approaches its real bell behavior.

Evaluation of selected properties of mineral fibers-based board, including the design of suitable purposes of its application
Sýkora, Radim ; Böhm, Martin (advisor) ; Múčka, Martin (referee)
This thesis evaluates properties of board based on mineral fibers. In first part of the thesis is conducted analysis of the literature, where are described materials based on basalt fibers. Here is also explained production of basalt fiber and its practical applications. Sandwich materials and materials with great fire resistance based on wood are also looked into. Following part describes options of aplication of materials with great fire resistance and mechanical a physical properties of materials based on wood.
Second part of the thesis lays out methodical approach to individual performed mechanical and physical tests. Characteristic of examined material is included. The last part deals with test results, comparing results with other selected materials, debating results and proposing possible applications of examined basalt board. With use of found data is evaluated suitability of the material for use for construction of sandwich panel.

Construction - Technical Analysis of wooden constructions
Pittnerová, Kateřina ; Múčka, Martin (advisor) ; Roman, Roman (referee)
This diploma thesis deals with four chosen types of vertical sheathing of houses in the passive standard and their overall thermo-technical and economic evaluation. At first, the materials which may be used in wood constructions of vertical sheathing of a house are described. Further, a design and thermo-technical assessment of each of the structures is performed. Wooden structures using environmentally friendly insulation are designed for three types of vertical sheathing and the system Ytong with external insulation is proposed for the fourth type, currently often used in the construction of passive houses in the Czech Republic. In order to comprehensively assess the building envelope, the composition of the roof and floor on the ground will be designed. The other part deals with the evaluation of the building envelope, separately for all four vertical sheathing options. An economic comparison of the envelope options based on the creation of itemized budgets will be carried out. Finally, the pros and cons of using each of the proposed envelope compositions will be evaluated.

Construction draft periphery timber structure in low-energy and passive standard
Přinosilová, Gabriela ; Múčka, Martin (advisor) ; Vladimír, Vladimír (referee)
The diploma thesis is focused on the design of the timbered wall composition considering the low-energy and passive standard. Main goal of the thesis is to calculate heat transfer coefficient U for four different types of the timbered walls and consequently evaluate if they comply with the requirements of low-energy and passive standards. The calculations show that the traditional concept of the timbered structures is inefficient for the mentioned energy standards. The minimal thickness of the timbered wall which will satisfy the requirements of the energy standards for low-energy and passive structure were calculated for the proposed four types of wall composition. For the calculations methods according to the applicable standards ČSN were used. To verify accuracy of these method and the performed calculations simplified numerical model was made in finite element software.

Mutual comparison exterior wooden saunas
Bartůněk, Václav ; Múčka, Martin (advisor) ; Trgala, Kamil (referee)
This work describes the structural design of contemporary outdoor sauna cabins. The manual is written with great detail on how to construct sauna cabins, both horizontal and vertical structures.
Listed below are the most commonly wooden cladding materials, sauna furniture and sauna equipment. Also discussed are the issues of electrical installation, ventilation and longevity of the sauna cabin.
Work also includes the characterization of the five possible sauna designs, including the comparison of the economic standpoint of the user. The outcome of the work is comparison of the saunas according to their properties.
