Alternative energy supplies for garden and week-end house
Novák, Michal ; Mazal, Pavel (referee) ; Venclík, Jiří (advisor)
This bachelor’s thesis contains abstract of alternative energy supplies for garde nand week-end house and describes their advantages and disadvantages. The selected alternative energy supplies are: water-power, solar energy and wind energy. Final part of bachelor’s thesis discuss with a construction machinery for wind energy useage and describes parts of machinery.
Design of Darrius rotor as source of electric energy
Novotný, Martin ; Houfek, Martin (referee) ; Vlach, Radek (advisor)
This bachelors thesis deals about possibilities to use alternative energy source - wind. Model of Darrieus rotor was build for learning purposes using accessible materials and tools. The build model was tested and measured to discover real functionality and characteristics.
Renewable energy sources in CR
Dubový, Ľuboš ; Šumpela, Pavel (referee) ; Fiedler, Jan (advisor)
The content of this bachelor study is the technical recherche, which deals with renewable resources of energy in Czech Republic with a view to the solar energy. The study contents basic charakteristic and disputableness of solar energy as well as its exploitation in Czech Republic. Then there has been introduced description of chosen concrete solar system.
Renewable energy sources in CR
Bulíček, Pavel ; Moskalík, Jiří (referee) ; Fiedler, Jan (advisor)
The content of this bachelor study is the technical recherche in the usage of the re-newable resources of energy in the Czech Republic with a view to the wind energetics. The study contents basic characteristic and disputableness of each type of energy resources, potential of the Czech Republic in exploitation of wind energy, description of chosen types of wind power plant and integration of wind energy into Transmission System of the Czech Republic.
Wind power station tower - calculation
Stein, Pavel ; Vrbka, Martin (referee) ; Nevrlý, Josef (advisor)
The target of this labour is to give summary of contemporary level of construction of wind power station tower. The first part describes importance and progress of alternative sources of energy, especially wind energetic in Czech republic. Next point concerns some construct options of wind power station tower and its basic elements. Close of the work is oriented to modern forms in problems of the wind power station tower and indicates options of modern development.
Analysis of colapse of family house during the house building
Babik, Juraj ; Bažant, Zdeněk (referee) ; Strnad, Jiří (advisor)
One of the first point was to create drawings of a projected state before collapse from photos that I had. The project is aimed on causes and reports of fallen wall, then results are compared with software results. The project solves also reports of gable walls that were intact. I solve temporary options of bracing for these walls, compares each variants while trying to ease and the low cost of solution. The result is recommendation how to prevent collapse of the structure.
Wind action on high-rise buildings
Damek, Marek ; Eliáš, Jan (referee) ; Nevařil, Aleš (advisor)
This thesis is focusing on comparison two approaches wind actions on high rise buildings. Determinist approach will consider by norm ČSN EN 1991-1-4. Stochastic approach by real wind speeds and synthetic generate wind speeds. Wind as a random value, variable on time and height. Model of water tower will use for the comparison.
Space structure of industry building object
Pelikán, Adam ; Švaříčková,, Ivana (referee) ; Šimůnek, Petr (advisor)
The subject of this project is the structure of the storage hall which is made of reinforced concrete. It is designed as precast frame (span of 18m), founded on pocket footings. The roof deck (non-rigid) consists of ribbed slabs. The cladding is made of sandwich panels (reinforced concrete and isolation) layed on foundation beam. The design is focused on the single typical frame. Roof girder, column and pocket footing are designed. Designed life of the structure is 50 years.
Character of pilot in the writings by Antoine de Saint-Exupéry
ŠIMONOVÁ, Kristýna
This thesis focuses on the research of the pilot´s character in chosen writings by the French author. While we can divide his writings into both historical and cultural context there is also an analysis of the pilot´s characterization together with the main themes contained in the writings. Antoine de Saint-Exupéry, who was an aviator and script writer but primarily an author, has come under the scrutiny of many biographers and movie adaptations so that Saint-Exupérys' legacy remains alive. The Little Prince is probably the writers' most famous work and although his others writings are comparable with The Little Prince, these have been overshadowed by the work. A lot of attention has been paid to Saint-Exupéry´s conception of morality, fear and death which are topics united into the pilot´s character and so it is interesting to mark out the main typical features. This thesis analyses and compares individual writing and identifies the common features which creates a simplified model of the pilot. If possible, the model will be compared with the author and we will mark his function in the tale together with his influence on readers.
Lifetime prediction of wind loaded mast and towers with respect to lateral and longitudinal wind spectrum
Pospíšil, Stanislav ; Lahodný, J. ; Janata, V. ; Urushadze, Shota ; Král, Radomil ; Hračov, Stanislav
The paper deals with a theoretical lifetime prediction of telecommunication towers, guyed masts and antenna’s cantilevers and comparison with the long-term measurements. A simple and practical calculation method is presented. The wind load is described taking into account the probability distribution function of the mean velocity and corresponding wind pressures. The dynamic response of structure caused by the turbulence uses wind models for both longitudinal and lateral direction. Structural response takes into account the contribution of more vibration modes. Based upon this knowledge, the number of cycles for certain time period together with the residual time life prediction of antennas cantilevers and cables was determined.
