Softwarový přijímač GNSS / Software GNSS receiver

Jedlička, Petr January 2020 (has links)
The thesis deals with the analysis and the reception of the freely available signals of the navigation satellites in the L1 and E1 bands of the GPS and Galileo systems. The described signal reception sections include the process of the acquisition, the carrier frequency and phase synchronization and tracking, the spreading code phase tracking, the signal demodulation and the channel decoding. The simulation of the entire receiver is performed in MATLAB. The deeply analyzed signal reception component is the one responsible for the carrier phase and frequency synchronization and tracking. In that case, more methods and their comparison are usually listed. The signal reception component, which is responsible for the carrier phase and frequency tracking and the spreading code phase tracking, is also implemented in FPGA.

Vliv genotypu na produkci konzumních vajec ve vybraném chovu

STRAKOVÁ, Karolína January 2017 (has links)
The aim of this thesis was to compare the indicators of egg production of hens which are bred for production of consumable eggs i.e. Hy-Line Brown and Hy-Line White in selected farms. Selected parameters of egg production were evaluated during 12-months-laying cycle. In the selected farm during the monitored period was achieved the intensity of laying 86,8 %, laying at the initial state 26.5 eggs, number of eggs included in first quality class 96.4%, mortality of egg layer 1.06%, consumption of compound feed per 1 egg 130.0 g and consumption of compound feed per 1 feeding day 110.8 g. Hy-Line Brown showed higher intensity of laying (88,0 %, respectively 85,2 %), laying at the initial state 26.7 eggs, respectively 26.1 eggs, lower consumption of compound feed 128.7 g, respectively 133.2 g. Hy-Line White showed a statistically significant higher proportion of eggs included in the first quality (97.3%, respectively 85.4%), statistically significant lower mortality (0.49% and 1.51%) and statistically significantly lower consumption mixtures per 1 egg (100.7, respectively 114.9 g).

Školící a rekreační centrum / The Training and Recreation Center

Lím, Štěpán January 2016 (has links)
Thesis Training and recreational center at the documentation for the execution of works. The building was designed so that the object is divided into two parts. The first part is a training and recreation center, which is developed to the level of documentation for construction. The second part is a space for accommodation, which is designed only as a preparatory study and work. The building is divided into three main units, which include middle entrance portion, training and recreational facilities and accommodation for clients and visitors. The leisure center facilities include a swimming pool, whirlpools, saunas and massages. There are lecture hall, projection room and small cafe in the area of training center. In areas 1.NP is restaurant. The building is brick of brick blocks. Foundation structures bearing walls are designed footings. Roof construction over the area of the training center is oblique, supporting elements are tie beams. Flat roof DUO is designed over other areas of the entrance and the accommodation parts. The entire building is insulated outer contact insulation. The building has a cellar.

Uvedení sklo-ocelových nosníků na trh a jejich expanze do zahraničí / Introduction of Steel-Glass Beams and Their Expansion Abroad

Palkovská, Nella January 2012 (has links)
The aim of this master thesis is to find an outlet for the new luxury architectonic component - steel-glass beam called GS-Beam and to introduce suitable strategies for GS-Beam rollout on the target markets. Czech market is too small and the predictions of Czech construction industry are not positive, therefore there is a need to find other markets where to pioneer GS-Beam. The United Arab Emirates were chosen as the source of current demand and the Russian Federation as future potential purchaser. Market potential is tested by PESTLE analysis and by Porter's Five Forces Model. This master thesis brings concept for foreign expansion of the company Static Solution, which should be sustainable in long-term perspective.

Optimalizace výroby těžkých ocelových odlitků / Optimization of heavy steel castings manufacture

Malý, Václav January 2011 (has links)
In its first part the work deals with the frequent defects of heavy steel castings. Experiments were carried out in very heavy bearing rings casting of cement kilns in order to reduce consumption of liquid metal and to increase the internal quality of castings. The progress was achieved by introducing new technologies; this thesis describes the technologies used and subsequently performs their comparison.

Nosná konstrukce polyfunkčního domu / Load bearing structure of multifunctional house

Martínek, David January 2018 (has links)
Master´s thesis is based on analysis and design of a load-bearing structure of multifunctional house. The main load-bearing elements in the vertical direction are the monolithic reinforced walls and the main load-bearing elements in the horizontal direction are monolithic reinforced concrete plates. The connection of individual floors is made of monolithic reinforced concrete staircases. The foundation of the building is realized through a system of strips foundation. Design drawings are made to selected elements of the structure.

Softwarový přijímač pro dálkový průzkum Země v pásmu X / X-band Earth Observation Satellite Software Defined Receiver

Zedka, Radim January 2019 (has links)
Práce se zabývá procesem návrhu digitálního přijímače pro signály družic dálkového průzkumu Země v pásmu X. V první části je uveden seznam družic které umožnují příjem vědeckých dat pomocí amatérských neautorizovaných stanic. Jsou zde vypsány základní signálové parametry některých družic, z nichž EOS-PM-1 je zvolena jako hlavní objekt pro návrh přijímače. Ve druhé části je použit software MATLAB pro simulaci družicového O-QPSK signálu v základním pásmu, mechanizmu kompenzace kmitočtového ofsetu, synchronizaci nosné, symbolové synchronizaci, rámcové synchronizaci a odstranění fázové dvojznačnosti vlivem modulace. Třetí část práce pojednává detailněji o implementaci jednotlivých bloků přijímače do FPGA při použití aritmetky s pevnou řádovou čárkou. Je zde popsána metoda pro verifikaci celého designu v reálném čase a závěrem je zde uvedeno porovnání výsledků měření touto metodou a výsledků simulace.

Létající atmosférický nosič pro vypouštění raket / Flying atmospheric carrier for rocket launches

Musil, Tomáš January 2021 (has links)
The main objective of this thesis is to introduce the reader to the problematics of air-launch and to a custom design solution applying this concept. The specifics of this method of bringing a payload into orbit are described and explained. Overview of projects which use aircraft to launch spacecraft is included. Determination of primary parameters of a launch vehicle designed to carry a payload of a specified mass is conducted. The required flight performance has been estimated, a computational model has been developed in software MATLAB, and a multidisciplinary optimization of the design parameters has been performed using a genetic algorithm optimization method. Parameters of the designed air-launched rocket are compared with those of a ground-launched rocket. According to the specific criteria, the Airbus A310-300 aircraft was selected as the most suitable transport aircraft to be used for launching the designed launch vehicle. The last part of the thesis is devoted to the proposal of necessary modifications and estimation of the flight performance.
