Static provision of baroque church
Kadlec, Jaroslav ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
The master´s thesis solves a static provision of the Baroque church of Saint James in Městečko Trnávka. The church was built in 1752 in Baroque style on the place of the original Romanesque church. It is a single-nave building with dimensions of about 46 × 20 m. The nave is followed by a massive square tower with a height of about 34 m. The reason for the restoration of the church are cracks in the external masonry and arch due to small space stiffness. The building will be reinforced by horizontal and transverse prestressing. They are designed prestressing tendons, called monostrands, using method of alternative cable channels. It will help to avoid other derformations and it will increase a stiffness of the structure.

Faults and Defects of Residential Real Estate from the Point of View of Thermal Technique and their Possible Impact on the Value of the Real Estate
Hlavsa, Petr ; Kolář, Radim (referee) ; Klika, Pavel (advisor)
This master’s thesis deals with issues of faults and defects of building structures in residential real estate in terms of thermal technique. This thesis deals with their possible impact on the value of a residential real estate. In the theoretical part of this thesis, properties and quantities, which are used for an assessment of the building structures according to legislature, are described. Assessments of the steady state temperature are described closely. The thesis mentions usual sources and causes of faults and defects, which frequently occur. The possibilities of the non-destructive assessment of structures are also described. The reparability of faults or defects is related to the influence on the price of real estate. The practical part of the thesis deals with the value of a dwelling in an apartment house, which is affected by a fault manifesting surface condensation. An analyzed technical cause of this fault is described. Possible ways of remedying are shown, including the quantification of costs. The apartment is appraised in a faultless condition and afterwards the probable impact of this fault on the price of apartment is determined.

Complex diagnostics of the family house
Tomanová, Jana ; Balkanský, Ondřej (referee) ; Schmid, Pavel (advisor)
This master´s thesis deals with the issue of the building from a clay. It is focused on defects and rehabilitations of these constructions. The introductory parts concerns with probable defects especially of clay buildings, furthermore with causes of the creation of defects, its depictions and the relevance. In the following part the methods of rehabilitation not only of clay buildings are presented. In this part the rehabilitative methods of foundation, vertical and wood constructions, which create mainly the structural support of the buildings, are described. In the second part, the structural and technical research of the current structure with farm part – barn is executed. The part of research is creation of the drawing documentation, description of disposition and structural and constructional solution of building, structural calculation of a part of construction, assessment of actual state of structure and prospective plan of proceeding and rehabilitation.

Buildings monitoring
Kopuletá, Jitka ; Žítt, Petr (referee) ; Schmid, Pavel (advisor)
The bachelor thesis is aimed at the passportization of the breakdowns and imperfections on the front facades of houses on Arne Nováka and Gorkého streets in Brno where the reconstruction of the area of Philosophical Faculty of the Masaryk University will be in progress. The first visual inspection was accomplished before the beginning of the construction works. On its base the monitoring sheets of the separate buildings have been compiled.

Electrical machines fault simulator
Krátký, Michal ; Krbal, Michal (referee) ; Šlezingr, Jan (advisor)
The goal of this bachelor’s thesis is the laboratory task focused on vibrodiagnostics of rotating electrical machines. The thesis is divided into theoretical and practical part. The theoretical part is made of information related to rotating electrical machine mainly its faults and technical diagnostics. Besides that the vibrodiagnostics is involved into the theoretical part as well. The practical part deals with the design of laboratory task focused on vibrodiagnostics of rotating electrical machines. There is shown how vibrations influence the machine during the operation. There is used asynchronous machine 1LA7080 and vibrometer MV-5L and noncontact tachometer UNI-T UT372 for this experiment. The second task is the starting current diagnostics. The starting current ofthe engine with the rotor asymmetry 1LA7080 and rotor symmetry 1LA7090 is going to be analyzed here. On these engines will be shown, how current flicks affectthe magnetic field of the engine in the air gap.

Evaluation of the technical condition of sewerage in small towns
Gembalová, Barbora ; Raček, Jakub (referee) ; Hluštík, Petr (advisor)
Bachelor thesis is focused on the evaluation of the number and severity of defects in the sewer network in small towns in the South Moravian region. At the beginning of the work I got to know appropriate legislation and clarification of basic terms. Fault statistics and other indicators of the technical condition of the sewer network were processed from conducted camera exploration. These data are processed by several factors, such as material, size profiles, sewer age and length of the sewer network. Data were processed in Microsoft Office Excel. We found, there is mostly concrete pipe in small towns, which is old. Based on the data will be necessary keep wrecking objects and sections cleaned or repaired.

RESEARCH AND DEVELOPMENT COMPOSITE MATERIAL WITH A HIGHER RESISTANCE TO HIGH TEMPERATURES
Válek, Jaroslav ; Durica,, Tibor (referee) ; Kolář,, Karel (referee) ; Sitek,, Libor (referee) ; Bodnárová, Lenka (advisor)
Concrete has many advantageous properties as regards resistance to fire. It is non-flammable and it has a low thermal conductivity. However, concrete structures, which are not designed for resistance against fire, show significant damage after heating. In particular, the explosive flaking with the consequence of weakening the reinforced concrete cross-section and exposing the steel reinforcement to the temperatures higher than critical temperature of reinforcement. There are only a few possible measures of preventing or mitigating the effects temperature load used. Ways of protection can be divided into two systems: active and passive. Active systems are designed to ensure the greatest possible reduction of temperatures the concrete is exposed to. Passive systems directly resist to high temperatures and fire. Design of composition of concrete with the aim of higher resistance to exposition to high temperatures belongs among the passive systems. A part of the work focuses on summary searches of the problems of concrete and reinforced concrete structures exposed to high temperatures and fire. The goal of the work is defining requirements for cement matrix based composite material and its design ensuring the highest possible resistance to high temperatures or direct fire.

Specifics of assessment of old concrete structures
Mička, Michal ; Žítt, Petr (referee) ; Cikrle, Petr (advisor)
The bachelor thesis deals with evaluation of properties materials concrete structures of former textile factory Vlněna from the 19th century in Brno. The content of this work is divided into the theoretical and practical part. The theoretical part deals with the description of the methods used in the research of reinforced concrete structures, comparison of the types of beams used in the past with used today and unlike the principles of the design of reinforced concrete structures in the 1920s and 30s of the 20th century compared to the present time. There are also described components, properties and technologies of concrete production in the period between the war and the comparison with the present time. The practical part consists of on-site examinations and sampling. A large part consists of the evaluation of laboratory tests on the test samples taken from the solved part. A total of 24 test samples were performed. It also compares the strength of the concrete reinforcement with the reinforcement used today.

Dependability Assessment of Fault Tolerant Systems
Suchánek, Martin ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
Reliability is an important part of various systems. The aim of the work is to create reliability models of some reconfigurable and nonreconfigurable fault tolerant systems and subsequent evaluation of their reliability indicators. The Uppaal tool is used to create models, along with the SMC extension, which is used for verification. The result of the work is the verification of models and evaluation of reliability indicators using the tool Uppaal SMC.
