The Innovation of oscillators in mechanical-electrical keyboard instruments
Prokop, Šimon ; Buzzi, Mario (referee) ; Jirásek, Ondřej (advisor)
The bachelor thesis deals with innovations of oscillators of mechanical-electric keyboard instruments, especially from the perspective of frequency spectrum innovations. On the basis of the original oscillators of the Rhodes Mk 7 instrument, innovative virtual models of these oscillators were created in SolidWorks, which were subsequently analyzed in Ansys. Subsequently, these assemblies were physically fabricated and tested. In the final evaluation, the signal spectra of the upgraded assemblies were compared with the original tone and the analyzed data. The theoretical part of the thesis also discusses basic signal processing methods and describes methods for evaluating sound perception using psychological acoustics.

Design of Automatic Trading System Based on Trend Indicators and Oscillators
Cibula, Peter ; Dostál, Petr (referee) ; Budík, Jan (advisor)
This thesis deals with the implementation of the software for automated stock trading based on trend indicators and oscillators. It describes the various signals that are provided by formations in charts and technical indicators, but also the possibility of using advanced artificial intelligence methods. This document describes entire development process of the software from individual parts to the folding of these parts into one system. It focuses on the optimization processes of individual parts, as well as a complete system. This thesis also deals with the testing of the system on historical data and its application on the latest data. It introduces the future plans, deployment options to the real market and its further improvement in order to develop ideal business system capable of autonomous thinking and trading.

Technical Analysis
Mičánek, Filip ; Doubravský, Karel (referee) ; Novotná, Veronika (advisor)
This thesis deals with technical analysis, which is used to predict future development of stocks. The first part describes the theoretical background needed for the next section. This is followed by analysis of the current state, which assesses the current situation. The main part is devoted to the creation of a program to support technical analysis for the novice investor and the demonstration of its use in trading.

Preparation for function demonstration of basic types of oscillators
Venhoda, Jaroslav ; Šotner, Roman (referee) ; Brančík, Lubomír (advisor)
Bachelor's thesis deals with basic types of oscillators. Oscillators were divided into groups in the introduction. For the practical implementation was chosen four different types of oscillators. For each type of selected oscillator was done circuit design. Subsequently, the design was simulated by PC software OrCAD PSpice. The proposal includes a possibility of the control device by switching between outputs and tuning oscillator's frequency.

Behavioral Model of Current Conveyor with Advanced Controllable Inter-Terminal Relations
Jagla, Lukáš ; Langhammer, Lukáš (referee) ; Šotner, Roman (advisor)
Bachelor's thesis deals with model of current conveyor with advanced controllable inter-terminal relations. The behavioral model based on commercially available active devices has been proposed and designed as real implementation (including BCP design for experiments). Features of the behavioral model are verified by PSpice simulations as well as by experiments. Proposed device is utilized for synthesis and design of unconventional types of electronically controllable sine-wave oscillators and electronically adjustable filters. Simulated characteristics of the behavioral model as well as proposed applications are compared with experiments.

Taxonomic trees of fluidic oscillators
Tesař, Václav
Fluidic no-moving-part oscillators generating fluid flow pulsation became recently very popular subject of investigations. The reason is their capability to increase efficiency of various chemical and physical/chemical processes. Also control of flows past bodies is more effective with pulsation. Advantages of fluidic oscillators are lowcost, robustness, long life, no maintenance, and similar factors associated with absence of mechanical moving components. New oscillator principles - as well as old nearly forgotten but now re-discovered ones - are currently developed. Sheer number of possible alternatives makes them difficult to survey. This paper attempts at clarifying the situation by proposing three different approaches.
