Metodika zkoumání rychlých a stochastických mechanických dějů / Methodology of fast and stochastic mechanical process researchKolomazník, Petr January 2008 (has links)
This diploma thesis deals with the research of fast processes. It delineates technique the process is captured by with following interpretation of the results received. Fast processes are captured using high speed video camera system Olympus i-SPEED 2. The actual object of measuring and examination was an air pistol and its initial velocity.

Aplikace vysokorychlostního kamerového systému při testování rotujících pryžových dílů / Application high speed camer during testing rotation rubber partsPešek, Jan January 2009 (has links)
This diploma thesis introduces Olympus i-SPEED 2 high speed video camera and its use in the testing of rubber parts. The results gained will be applied to tyre tread development. Two mutually connected high speed cameras were used to record the testing process. Final recordings were put together in order to create panoramic photos.

Analýza tvorby třísky pomocí digitální vysokorychlostní kamery / Analysis of chip forming mechanism with a high-speed digital cameraKopřiva, Antonín January 2011 (has links)
The aim of the diploma thesis is to present the main theory concerning high-speed cameras, their usefullness in industry and to present the cameras available at the market. A few experiments have been done focused on the right choice of an objective, lighting of the scene or setting of the cameras. A special equipment has been invented for a better process of measuring followed by experiment aimed at boring a cutter in materials chosen beforehand. The speed and the acceleration of the cutter was ana-lyzed by means of MotionMeasure software in another experiment.

Výroba součásti vysokorychlostním stříháním / Production single parts by techlogy high - speed cuttingVálka, Petr January 2011 (has links)
This thesis deals with technology design of stamping production made of CuSn4 bronzy band by using high-speed cutting. First part of the thesis is focused on description of cutting technology, second part analyses high-speed cutting technology. Thanks to both analysis a module sequential die was constructed. The die is connected to the BSTA machine via quick-clamp system. This BSTA 250 machine produced by Bruderer company was chosen based on technology calculations. All necessary calculations, selected parts of drawing documentation as well as technical-economical evaluation of the technology design are mentioned in the thesis.

Parní turbina / Steam turbineČípek, Petr January 2013 (has links)
The aim of the thesis is to design a high-speed steam turbine as a small energy source. Steam turbine consists of a high-pressure, a medium-pressure and a low-pressure part with a removable condensing module. High-pressure part is designed to perform a single-stage radial turbine with axial steam outlet. The work also includes the layout of the modules and sections. To design individual parts are used steam table „X-steam“.

Testování vysokorychlostního nástroje pro překlad IP adres / Testing of high-speed tool for network address translationVrána, Roman January 2016 (has links)
This master thesis presents a topic of testing network address translation. It describes basic principles of network address translation and general methods for testing network devices. These methods are then applied on NAT devices. Thesis then introduces a design of a framework for performing functional tests. The designed framework is then implemented as a part of the thesis and used to test a newly developed high-speed NAT application.

Re-Tooling an American MetropolisHott, Robert Shawn 16 April 2010 (has links)
Re-tool:
v.tr. re-tooled, re-tooling, re-tools
1. To fit out (a factory, for example) with a new set of machinery and tools for making a different product.
2. To revise and reorganize, especially for the purpose of updating or improving.
The American ideals inherent in the suburbs are the promise of space, affordability, convenience, and traditional family life; conversely the public realms of the suburban typology become disconnected from each other as well as the larger city. The Generic City condition in which the periphery is no longer captivated by the center from which it was created is pervasive in the American landscape.
Public space within the city has been consumed by their auto-centric infrastructural requirements, creating a loss of activity and identity. "Lowly, unpurposeful and random as they may appear, sidewalk contacts are the small change from which a cities wealth of public life may grow." Connecting people and places to one another and the metropolis that feeds them is essential for a properly functioning society.
One example of an American city afflicted by auto-centrism and pedestrian marginalization is Tampa. The solution to Tampa's disconnection is a transit oriented development model in which there are localized areas of higher density that become nodes along a public transit route, thereby connecting areas of low density. By creating transportation nodes, places will become better connected in time and space. Establishing a more social form of transit in the Tampa Bay region will provide the opportunity for the creation of a secular cathedral of transportation. The Infrastructures we erect, just as the monasteries in the Middle Ages, must seek to enliven the communal and artistic traditions that make civilization and culture meaningful.
The network of light rail connecting disjointed areas in Hillsborough will be linked to a high speed rail connecting major metropolitan areas across the state. This central downtown node will be manifested as a multi-modal station which incorporates multiple functions into an existing single use environment to densify the urban core of Tampa, create denser housing, and reconnect people to places. The main area of focus is the rail station and its overlap of program to create density and intensity so that connections with places and culture will be reinforced. The station will become a major public space of amenity and gathering point for the community.

Vibration Control of a High-Speed Railway Bridge Using Multiple Tuned Mass DampersBeygi, Heydar January 2015 (has links)
In the current thesis, the Banafjäl Bridge located on the Bothnia line (Botniabanan) in northern Sweden was studied. The bridge is a 40m long composite ballasted high-speed railway bridge. A 3D FE model of the bridge was developed using a commercial FE software, Abaqus. The FE model was calibrated against the measured data of the bridge. The dynamic response of the bridge's FE model was investigated under the dynamic load of the passing HSLM-A train using modal dynamic analysis. The vertical acceleration induced by excitation of the passing train exceeded the permissible limit of 3.5 m/s2 for the speed range of 220-240 km/h. Thus, damping solutions using multiple tuned mass dampers (MTMDs) were investigated. According to the results of this study, a 4 tonnes MTMD system consist of 5 parallel TMDs attached to the mid-span of the bridge could effectively control the undesired vibration of the bridge. The suggested solution could account for the changes in the stiffness of the bridge caused by freezing and ice forming in the ballast.
