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.
One span frame bridge
Černý, Pavel ; Juříček, Lukáš (referee) ; Nečas, Radim (advisor)
The aim of this bachelor thesis is the design and analysis of bridge across the river. Three variants were designed. The structure was designed as a one-span frame bridge with a parabolic haunch with of span range of 24,0~m. The calculation of load efects eas made in software Scia Engineer and for evaluation was used MS Excel. Both design and relevant drawing documentation of the bridge deck and abutment.
Overpass bridge across the highway
Černý, Pavel ; Šopík,, Leonard (referee) ; Nečas, Radim (advisor)
The topic of this thesis is detailed design of the supporting structure of a bridge. Three variants are designed. The structure is designed as a single beam bridge of 6 spans. The calculation of load efects make in software MidasCivil 2019 and Scia Engineer 18.1. The subject of the expertise of the structure is service limit state and ultimate limit state. For evaluation of cross sections is used MS Excel. Both design and relevant drawing documentation of the bridge deck and substructure. The design and assessment are according to the europien standards.
Study of the thermal and light conditions in the automobile headlamp with built-in light source of the new generation
Zachar, Martin ; Černý,, Pavel (referee) ; Černý, Pavel (referee) ; Raudenský, Miroslav (advisor)
This thesis deals with automotive headlamps, focusing on layout of temparature field and its influence on thermal stress of used materials, describes their history, kinds and ongoing research. Thesis shortly describes light and its characteristics, heat and heat transfer and means of temperature measurement. Main part of the tesis is dedicated to measuring front headlamp serving as a fog light, concretely measuring temperature field and illuminance depending of ambient temperature. Thesis contains everything from the first preparations, creation of measuring circuit, programming of measuring to processing acquired data. Thesis also compares cooler used for cooling luxmeter sensor, the comparision is between measured values and created simulation.
Web Browser for IP Cameras
Černý, Pavel ; Veigend, Petr (referee) ; Zbořil, František (advisor)
The aim of the work described in this thesis was to enable live video streaming from IP cameras to selected users, using simply a modern web browser with no need to install special client-side software. The solution was found by utilizing programs FFmpeg (for communication with camera and video conversion to WebM format), Stream-m (for distribution of the data received from FFmpeg to clients), and a newly-created web application built on the Spring framework, which was used to control the aforementioned programs, and also allows camera management and user authorization. The resulting system reduces the effort required for client nodes deployment and maintenance. Thanks to the image size downscaling, the system brings about a considerable reduction of data flow in the network caused by camera output, and minimizes the load on client computers.
Citybike
Černý, Pavel ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
Content of this diploma thesis is a construction design of human powered vehicle for city ride with a focus on seniors. It deals with the issue of bicycle in city traffic and rates construction modern citybikes with a view to their weaknesses for the purpose. The basis of this work is a design frame with custom geometry, which is fitted commonly available components. Using FEM analysis are revealed critic areas of construction and results are used to optimize the frame.
Development of highly resistant composite using secondary raw materials and cast basalt
Černý, Pavel ; Jakubík, Aleš (referee) ; Drochytka, Rostislav (advisor)
The diploma thesis deals with development of high resistant composite, which brings its properties closer to the melted basalt products. This fact will allow substitution of basalt elements in hostile chemical environment by newly developed material and completes its product line. High resistant composite also consists of secondary raw material in highest possible amount. Material that is being evolved carries high strength, abrasion resistance and is also resistable in hostile chemical environment.
Composite with a high proportion secondary raw materials and cast basalt
Černý, Pavel ; Bydžovský, Jiří (referee) ; Drochytka, Rostislav (advisor)
The bachelor thesis is focused on the development of new composite into sewage sewers based on suitable combinations of binders and fillers, especially with the use of secondary raw materials. The composite should replace the cast basalt products with its properties, which are used in the linings. The proposed composite will be unique by his properties, primarily chemical and heat resistance as well as abrasion resistance.
Prednasky.com - system for automatic lecture processing
Černý, Pavel ; Beran, Vítězslav (referee) ; Szőke, Igor (advisor)
The objective of this thesis is to create system for automated processing of the video lectures. There are two main parts in this thesis. Bash Framework, which is created from several separated atomic tasks. At the beginning we have a simple video prepared for processing. When it is processed, there are added intro part, subtitles and synchronized presentation. Second part of this thesis is a web application. It is designated for playing, editing and creating videos. Further it provides process management of created framework and whole system administration.
Basic working and construction principles of electronic vehicle motion control systems.
Černý, Pavel ; Ambróz, Richard (referee) ; Laurinec, Marián (advisor)
This paper provides an overview of basic electronic assistance systems, focusing on active safety. The centre of interest of this work is an antilock braking system (ABS), an antislip system (ASR) and vehicle stability system (ESP). It describes principles of working and the main parts of the structure. The work also deals with the modern trends in selected active safety systems such as electro-hydraulic system (SBC), a system of automatic emergency braking (AEB) and electronic wedge brake (EWB).
