Actuators in aviation
Jetela, Václav ; Horák, Marek (referee) ; Bencalík, Karol (advisor)
The bachelor thesis with name “Actuators in aviation” deals with complete review of hydraulic and electric powered actuators used in aircrafts in a first part. Second part of the thesis is dedicated to review of hydraulic systems. Each chapter contains description of function and schematic drawings. There are mentioned construction designs of actuator test stand for performance testing. Last part of the thesis includes comparison of actuators according to the performance and application in aircrafts.

Automatic Trading System for Currency Pairs Using Technical Analysis
Padyšák, Jan ; Stoklásek, Libor (referee) ; Budík, Jan (advisor)
The aim of this work is to create an automated trading system for trading currency pairs using technical indicators and technical analysis. The proposed trading system is tested and optimized on historical price data. To verify the robustness of the proposed system was used walk-forward analysis. Automatic trading system also uses rules for position sizing and risk management of open positions. Created system is profitabel on historical price data and also in the walk-forward analysis.

Accelerated endurance testing of electromechanical airplane actuator
Fritscher, Matyáš ; Juračka, Jaroslav (referee) ; Klištinec, Dávid (advisor)
This diploma thesis, created in cooperation with Honeywell International, s.r.o., focuses on long-term durability testing of electromechanical actuators (EMA) for aerospace applications. Due to the current trend of replacing hydraulic actuation with electromechanical actuation, it is necessary to develop new procedures for the testing and certification of these devices. The research conducted provides an overview of the standards relevant to the development of accelerated EMA testing. The work also describes a specific EMA long term life test and analyzes the results obtained. Two key parameters affecting EMA performance and lifetime are presented and the associated actuator components are identified. Several possible modifications based on current results are also suggested. Finally, the thesis presents conceptual proposals for accelerating similar EMA tests. The results of this thesis can provide useful input for the design of future accelerated EMA tests, thereby helping to reduce the cost and time associated with their development and market introduction.
