The failures assessment as the cause of car accidents
Řehák, Miloslav ; Semela, Marek ; Drahotský, Ivo
The article deals with the issue related to recognition and assessment of the failures or the defects as the cause of car accidents . The great emphasis is laid in the need to safeguard the damaged car parts shortly after a traffic accident and their proper storage, that ensure their eventual further examination as a source of a correct analyses of the car crash event. The practical examples are given , e.g. how not taking the samples of the damaged car parts can make a correct analyses impossible, or on the other hand, how a timely inspection of a car right after a traffic accident has happened can lead to the better and more correct analyses. The final conclusion is given in the end of this work: in case the decision about taking and a storage of the damaged car parts has not been made right at the location where there was a traffic accident, the possibility of providing the correct analyses decreases significantly.

Issue of detailed building condition survey processing of building constructions
Šmahel, Milan
Processing of expertises in litigations in the area of damages caused by civil engineering on other owners‘ surrounded ground constructions led the author to write this contribution. Condition survey of current state is done on other owners‘ surrouded buildings before working constructions, mainly on underground structure, engineering and ground constructions, start. There are sometimes protracted litigations and expertise processing in determination of damage level in case of damage in connection with such construction. That is why the author deals with the issue of building condition survey and decisions made by both a client and a processor about details and distances from a place of constructions when building condition survey is proceeded.

System of Identification Solder Joint Failures
Vejmola, Tomáš ; Řezníček, Michal (referee) ; Šandera, Josef (advisor)
This paper describes the draft and implementation of a system for identifying failures on the soldered joints from already existing system, which is, however, limited by dependence of the operating system of the human factor. The innovated system provides us an automatic testing of soldered joints using a computer, with subsequent processing of data electronically using the corresponding software. The first part is devoted to the theory of the formation of flaws on the soldered joints and to the familiarization with uninnovated system. Subsequently, work continues with the practical part, which introduces us the procedure and implementation of the innovated system for identifying failures on the soldered joints. The final part of this paper is an evaluation of the results and fulfilment of work requirements.

The Continuity Indicators Calculation of E-ON ČR Distribution Network Segment
Girga, Eduard ; Černý, Pavel (referee) ; Paar, Martin (advisor)
The aim of this master’s thesis is calculation and analysis of reliability indicators of the company E.ON Česká republika, s.r.o. distribution network in the south Moravia territory (area of former Jihomoravská energetika) for the period of one year, from 1st November 2008 to 31st October 2009. We consider events incurred on overhead or underground lines of level of high voltage or directly connected with these lines. Events originated from extensive disaster interruption of electric energy supply caused by particularly unfavourable external effects are not considered, because network components can not be efficiently dimensioned on those influences. Known aspects of the events are time of origin, time duration, place and cause of failure inception. Analysis of reliability indicators is accomplished according to different point of view. The first aspect is the hours of day, during which the event lasted. The second aspect is the hours of day, during which the event incurred. The third one focuses component pointed as reliable for the origin of the event. The last standpoint is percentage load of the line outlet, on which the event occurred. We can ordain this load as the proportion of current flowing through the line outlet in the time of event inception and of the value of maximum current set up on the protection of the line outlet. Indications mentioned in the last sentence were searched in the dispatcher centre thanks to graphical interface of application RIS JME Brno. In the theoretical part of the work there is described the structure of distribution network and its fundamental influence on the continuity of electric energy supply, the ways of evaluation and increasing of electric energy supply reliability, regulation of continuity of electric energy supply with emphasis on regulation in the Czech Republic valid until 26th February 2010 and since 27th February 2010. The last theoretical part focuses on definition of failure and differentiation of failures according to various aspects.

Methodological guide and digitization of gear pump
Ševčík, Ondřej ; Nevrlý, Josef (referee) ; Nečas, David (advisor)
The aim of this bachelor thesis is to provide a methodological quide of U10 type gear pump. In the first part of the thesis, analysis of individual pump components including its main parameters is presented. The next part is focused on the identification of the defect suggesting the instructions for the reparation. All the operations such as dismantling, inspection, reparation, and assembly are described in a detail in a form of the technological processes. After the reparation, an operating test was conducted to verify the functionality of the pump. In addition, all the components of the pump were digitized by using SolidWorks CAD system. The last chapter provides FEM analysis of the cogwheels contact. For this purpose, computational system ANSYS Workbench was used.

New trends in automatic systems maitenance
Císař, Radek ; Vdoleček, František (referee) ; Lacko, Branislav (advisor)
Bachelor's thesis deals with new trends in the maintenance of automated systems. It focuses on the list of problems that arise in the operation of automated systems. Proposals for addressing these problems are trying to eliminate or at least eliminate. These problems should draw attention to the errors associated with the design and operation of these systems appear. The proposed solutions show new trends and possible directions of development of these systems.

The Architectural and Engineering Research of the Building Construction
Slavětínský, Šimon ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The subject of this bachelor thesis is the diagnostic survey of the arch railway bridge, which is situated in city called Hulín at the Railroad between Kojetín – Valašské Meziříčí in 16,019 kilometer. The thesis contains description of construction and technological survey and diagnostic methods, which includes evaluation of essential characteristics of masonry structures. The practical part contains processing of diagnostic survey. Its result is determination of material characteristics of the structure.

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.

Diagnostic analyzes of an existing family house
Novotný, Jaroslav ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
The thesis is mainly a structural engineering investigation of an old family house in Mladecko, Opava district. The whole object was measured, documented and examined; and after finding a series of defects, the aim of the theoretical part became to describe problematics of humidity and moisture in buildings. Moreover, because of the absence of previous documentation, there was a reason to carry out a brief historical study of the evolvement of rustic buildings, that became the second part of the theoretical work.
