Configuring and testing the faulted phase earthing functionality using the ABB protection and control terminal
Švec, Ondřej ; Topolánek, David (referee) ; Jurák, Viktor (advisor)
The bachelor thesis deals with the possibility of replacing the autoreclosing by the method of faulty phase earthing. The faulty phase earthing method is used for compensated networks, but the aim of this thesis is to apply this method to resistively grounded networks as well. The faulty phase earthing automation configuration is applied using the REF615 terminal from ABB and is performed using the PCM600 programming environment.
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.
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.
Identification and detection of defects on the PV system - operational measurement
Leitman, Valentín ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This work deals with the problem of identifying and detecting faults in photovoltaic systems. This thesis includes theoretical knowledge related to photovoltaic panels, the definition of measured parameters of the PV system and five ways how to identify faults in PV systems. The last part of this bachelor thesis deals with the author's contribution, which is to introduce a system for continuous monitoring data. System for continuous monitoring of data consists of measuring the power output of a photovoltaic panel and measurement using optical diagnostics using thermal camera. In conclusion are summarized individual knowledge, evaluation and recommendation of appropriate measurement methods for the detection of faults in PV systems.
Inspection of the implementation of reinforced concrete structures
Juráň, David ; Vymazal, Tomáš (referee) ; Cikrle, Petr (advisor)
This diploma thesis deals with the control of the implementation of reinforced concrete structures. The theoretical part deals with the issues of this theme. There are presented individual work processes of the implementation of reinforced concrete structures, accesses of valid standards, used diagnostic methods and also inspection and test plans for cast-in-place reinforced concrete structure. The practical part is divided into three chapters. The first chapter applies with the most frequent defects in new reinforced concrete structures and two remaining chapters with the inspection of newly built structures for which arose misgivings about the quality of execution.
Diagnostics of structures in the evaluation of faults and defects
Stehlík, Petr ; Kocáb, Dalibor (referee) ; Schmid, Pavel (advisor)
This bachelor's thesis deals with research into methods of measuring and evaluating faults and defects in structures. A part of this thesis is an analysis of the legal issues in regard to investigations of structural defects in buildings. This thesis also includes a practical study of a family house in Černopolní street, which was affected by masonry cracks. The study details the collection and processing of data and analysis of the possible causes of the failures.
Evaluation of technical condition of vehicles
Košťál, Ondřej ; Tylšar, Vladimír (referee) ; Panáček, Vladimír (advisor)
Diploma thesis will be addressed about issue of vehicle inspection at Inspection stations in Czech republic and neighboring countries. Thesis will be concentrate about legislation, metodics, evaluation of technical condition and influence of dangerous faults to vehicle operation. One part of thesis will be proposal of provision to increase safety in vehicle tradic.
Providing measured documentation of existing structural and technical conditions of a single-family house in Brno
Zahradníková, Lenka ; Najt, Eduard (referee) ; Šmahel, Milan (advisor)
The diploma thesis deals with the passport of family houses and its creation. The first part describes the building condition survey from a theoretical point of view, its advantages, purposes and sorting, possible owners and so its legislative background. Thereafter it describes in detail the procedure of making the passport and applies the procedure on a particular family house in Brno. Medium passport of the family house focuses on describing the structural and technical condition. It also describes the current faults, errors and methods whose reveals them. Subsequently, the proposals for solution of these adjustments follows together with the resolution of emergency in specific cases.
ALU Built-In Self Test
Bednář, Jaroslav ; Růžička, Richard (referee) ; Drábek, Vladimír (advisor)
This work deals with faults, errors and failures, which can occur during manufacturing and long term operation. Work describes the various failures and fault models. There are some approaches to get fault tolerant systems, mainly in hardware. The thesis continues with a summary of methods for ALU software testing. The last chapter is about tests generation for microcontroller MSP430.
