Zvýšení průtoku chladící vody pro absorpční chladící agregáty ve stanici zdroje chladu na JE Dukovany / Increasing the flow of cooling water for absorption cooling systems in the nuclear power plant Dukovany

Dvořák, Josef January 2015 (has links)
The thesis focuses on comparison of the original and the new solutions of cooling water circuit of the York cooling units for the purpose of cooling water flow increase for the absorption units in the Dukovany Nuclear Power Plant. The individual parts of the cooling units that were changed and modified within a reconstruction are described here. The aim of the work is also to process and compare the original and the new solutions of the cooling units and the cold source station from the available measured data. The data are processed into illustrative graphs and tables. Based on the obtained data we can observe the changes achieved by the reconstruction that have affected the effectiveness of the cooling units.

Rozhledna na jižní Moravě / The Viewing Tower in South Moravia

Turková, Martina January 2016 (has links)
This master’s thesis deals with the design and static assessment of a lookout tower in The Brno Zoological Garden situated on the hill called Mniší hora. The construction of the lookout tower is meant to be of a circular ground plan and its overall height is 31 m. The construction was designed in two variants. For both methods was used a combination of steel and solid or glued laminated timber. For detailed elaboration was selected only one variant. The lookout tower was assessed in a Scia Engineer 15.1 software.

Návrh zavěšené lávky pro pěší / Design of cable-stayed pedestrian bridge

Uher, Lukáš January 2017 (has links)
This diploma thesis aims to design a structure of pedestrian bridge over the Svratka river. To make a preliminary study of possible bridging, three different outlines were drafted. The cable-stayed variant was selected for further analysis. Two towers, inclined in both their longitudinal and transverse direction, support a cast-in-place post-tensioned concrete deck through stay cables anchored in the tower and the deck. After determining the desired initial state, a finite element analysis was carried out using the Ansys software. The capacity of all main load-bearing elements was checked so it meets the ULS and SLS design criteria in accordance with EN 1992 codes.

Hasičská stanice typu C2 / Fire Station Type C2

Wojcik, Jindřich January 2017 (has links)
Diplom thesis is about design of the fire station of type C2 for the HZS. The building is divided into two parts. First part of a building is designed as a rectangular recessed floor. The first part of building consists of two floors and one underground floor. Roofed by a single-layer flat roof of soft PVC. The building will be used to perform the services, the fire brigade. It will be used 24 hours a day. In the basement is located warehouse, HVAC room, utility room and a lounge with an alternative source of electricity. On the first floor are designed garages for storage technique and also the dressing room, workroom, washing box, warehouse, room for chemical-technical service and concierge. The second floor is designed to serve firefighters. The second part of the building is a training tower, which will be used to train firefighters and for drying hoses. The training tower is designed as a simple steel structure with four floors. The project was developed in the educational version of ArchiCAD 16th project is designed in accordance with the requirements of a layout, architectural design, structural design proper and safe use of the building.

Telescopic Tower Facilitating Installation of ≥12 MW Offshore Wind Turbines

Pettersson, Martin January 2020 (has links)
The trend of offshore wind power is bigger and bigger wind turbines. Turbines are now becoming so big that existing installation vessels no longer are feasible and new bigger installation vessels are needed. Ship owners hesitate to order new vessels worried that the rapid turbine growth will continue and make also the new vessels obsolete in a few years. This can create a bottleneck in the offshore wind market.   This thesis assignment attempts to develop a telescopic tower as an alternative way of installing offshore wind turbines. A telescopic tower can decrease overall height and COG during marine installation, giving opportunity to install the largest wind turbines also with existing vessel fleet.   The method for developing the telescopic tower is to first find the main problems and functions of the concept. A design basis based on a 12 MW reference wind turbine is developed. Based on this reference turbine different solutions to the main problems and functions are developed by creative thinking, literature research, modelling, calculations and analysis. A cost/benefit analysis is performed to investigate if there is any economic potential in the developed solution. To complete the study other installation methods and telescopic tower concepts are investigated for benchmark comparison.   The telescopic tower will have two sections. Shoulders are welded to the inner wall of the lower tower. The upper tower fit inside the lower tower and a telescopic mechanism is installed below to lift the assembly as the mechanism climb the shoulders of the lower tower. The telescopic mechanism works much like a pin and hole mechanism used for jack-up rigs. The pins engage/disengage with the shoulders by the movement of linear actuators. The vertical climbing motion is provided by hydraulic cylinders. The power source is an HPU placed on the wind turbine external platform.   To connect the upper and lower tower permanently a friction connection with long slotted holes is used. This connection is developed for assembly of onshore towers in an EU-sponsored project called Histwin. The walls of the lower and the upper tower overlap at the connection and are pressed together by pretensioned bolts to create a friction surface that hold the loads from the upper tower.   The conclusion is that the telescopic tower is technically feasible and can be installed by the existing installation vessel fleet. The economic feasibility is dependent on the specific project characteristics, but there are scenarios where the telescopic tower can have great economical upside.

Archeologie tvrze v českých zemích. K počátkům středověkých opevněných sídel / Archeology of the Fortified Manor in the Czech Lands. To the beginnings of the Medieval Fortified Residences

Laval, Filip January 2013 (has links)
Archaeology of the fortified manor in the Czech lands To the beginnings of the medieval fortified residences The work is dedicated to the medieval fortified manor in the Czech lands with regard to the need to formulate new questions. He marginally considers the questions of actual and historical terminology and its semantic content. To explore the functions of the fortified manors the structure of the associated settlement is discussed. A substantial testimony is attributed to some of selected written sources pointing to the legal-historical or jurisdictional context of "private" fortified settlements/residences. A separate chapter is devoted to the analysis of several examples of archaeological research from the Czech lands and from western parts of Europe, which revealed situations classifiable to fortified manor, respectively castles, which was preceded by much less or not at all fortified settlements, while maintaining close spatial continuity. So the questions concerning the beginnings of that type settlements are pronounced. With this packet of problems the work deals applying a comparative analysis that leads to some reassessment of the importance of the Romanesque church with the western tower as a kind of reduction of the castle model known from contemporary (12th century) Western European regions...

Rozhledna / Lookout tower

Jedzoková, Patricie January 2022 (has links)
The object of the diploma thesis is design and assessment of a steel lookout tower situated in Beskydy mountains. Two different variants were designed. The first variant is of square shaped plan and the second one is of hexagonal shaped plan. Both variants are spatial truss structures. They are shaped as hourglass. The variants were compared and the first one was chosen to be further developed. The lookout tower is 36 meters high and it is divided by floors. One floor is 3,6 meters high. The widest section is 8 meters, the narrowest section is 5 meters wide. The structure is pin-supported into concrete foundation. The concrete is class C25/30. The roof covering is made of trapezoidal sheet of class S280GD. Each steel element is made of steel of class S355.
