This thesis deals with structural design of a steel frame footbridge with wheelchair access, which will lead pedestrian and cyclists‘ traffic over the river Thaya in Břeclav. The footbridge is a structure of one field, lightness of a bridge opening is 58,92 m and a span length is 60,25 m. A light width of an area between rails is 2,5 m. The footbridge is constructed of a truss beam cable – stayed bridge on an oblique pylon of 20,0 m length and a preloaded steel suspender. The thesis was processed according to valid standards ČSN EN.

The diploma thesis deals with the design of a bridge in Most. It bridges the railway line and the river Bílina. Three possible variants have been proposed. One of the variants has been selected and further elaborated. The solved variant was an arc with a suspended pre-stressed bridge beam. The supporting element is a reinforced concrete backbone. The construction is built on a ring. Static analysis partly includes the effect of phased construction. The design was assessed according to EN.

The diploma thesis is focused on the measurement of forces acting between the tire and the road. There is an outline of tire and tire models problematic in the opening part. In the following part, the rear right suspension of the formula student car was mounted with strain gauges and the data logging system was described. There is also a multi-body model of the rear axle created in Adams/Car and SAMS software, that is able to calculate forces acting between the tire and the road, taking the measured forces in the suspension, rocker position, and throttle position into consideration. After a series of calibrations and verification measurements, the measurement on the test track was made, with data analysis focused on forces acting between the tire and the road.

This diploma thesis concerns with analysis and dividing of frequency synthesizers and design of DDS, PLL synthesizers. Base types of frequency synthesizers are described including differences between methods of their operation. Base circuits of both – DDS and PLL synthesizers and other important circuits are described in details at design part of this thesis. Design of DDS and PLL synthesizer is described in particular sections. Both synthesizers are directly realized and stand-alone control applications are created. PLL synthesizer is also ready to control thru Agilent VEE program environment. Particular example application is designed in Agilent VEE. This application is used as basis of attached lab project.

The aim of this diploma thesis is the design of the roofing of an ice hockey stadium situated in Žďár nad Sázavou. Plan view dimensions are 55 m x 77 m. The structural height of the roof varies from 10 to 17 m. The roof itself consists of pipe truss girders with a span of 55 m, which are supported by columns on each side. The girders are suspended by a load-carrying arch with a span of 96 m and a camber of 29 m through a system of pre-stressed cables. To determine the internal forces, structural analysis software Scia Engineer was used. Individual elements were then manually designed.

This work deals with three-phase active rectifier control. In first, theoretical part it describes several control strategies with focus on voltage oriented control. For this type of control a design is worked out, and created model and its simulation is described. Second, practical part deals with realisation on microcontroller TMS320F28335, which is main processing unit of device lent by company Elcom. Therefore in this part abilities and settings of the controller along with developped control algorithm are described. Reached results of measurement are then presented and in the conclusion they are evaluated.

In my thesis, I created a study of plan curved cable stayed pedestrian bridge. As the main construction material is used prestressed concrete. Suspenders and railing are made from steel. The footbridge has a length of 130,00 meters and a width of 3,70 meters. The plan shape of the structure is composed of two oposite arches. Bridge deck is made of box girder. The bridge deck is single-side suspended on two concrete pylons with a height of 39,00 m. Pylons are supported by suspender.

The subject matter of this master thesis is to design pedestrian bridge across the river Nitra in a city Nitra. Out of three possible solutions arch bridge was considered to be the most optimal system for given situation and it was analysed in detail. The design and assessment of load-bearing structure was evaluated acording to valid standarts. The main goal was to comply with ultimate and serviceability limit state. Global calculation model was created in ANSYS Mechanical APDL 21 R2. Model of the slab of the deck in the cross direction was performer using SCIA Engineer 19.1. Load capacity of some cross sections was verified manually and some using computer software IDEA Statica 21.0. This thesis is extended with drawings of sequence of construction, detailed drawings of the bridge and visualizations.

The main aim of the thesis is to develop a solution of a frequency synthesizer for a microwave communication systems. Specifically, it suggests a design for frequency synthesizer with phase-locked loop. At beginning of the thesis the principle and basic properties of this method of signal generation are explained. Then it is followed by a brief discussion of the parameters of synthesizers and their influence on design. Another part of the work is the analysis of circuit the frequency synthesizer with the phase-locked loop MAX2871, which is followed by a proposal for the design of the frequency synthesizer module hardware. The last part of the work deals with practical implementation, verification of function and measurement of achieved parameters and their evaluation.

The presented thesis deals with the design and assembly of the generator for pulse magnetron sputtering. The designed device is capable of generating two square wave signals via its counter-working outputs. Both signals have independently adjustable frequency, pulse count and duty ratio. Both signals originate from two frequency syntheses controlled by microcontroller PIC16F877A. All the settings are entered by four buttons and are shown on an alphanumeric display with 16x4 characters. The duty ratio is adjusted using a special module.
