Design of Optical Wavelength Selective Switch
Sikora, Vojtěch
Optical circuits switching is a rapidly growing area of photonic networks. With increasing requirements of photonic services only software defined networking (SDN) allows flexible and effective networks creation. The paper shortly introduces technologies of optical circuits switching, especially WSS (wavelength selective switching) for WDM (Wavelength Division Multiplexing) networks. Using specialized software VPIphotonics the WSS 1x4 for an interconnection between Prague, Brno, Ostrava and Vienna was designed.

Wavelength selective switching
Sikora, Vojtěch ; Kočí, Lukáš (referee) ; Münster, Petr (advisor)
Optical circuits switching is a rapidly growing area of photonic networks. With increasing requirements of photonic services only software defined networking allows flexible and effective networks creation. This bachelor thesis introduces technologies of optical circuits switching, especially wavelength selective switching node as reconfigurable optical add drop multiplexer used in wavelength division multiplexing networks. Using specialized software VPIphotonics the WSS 1x4 and ROADM for an interconnection between Prague, Brno, Ostrava and Vienna was designed.

Processing of signals from fiber optic sensors
Sikora, Vojtěch ; Urban, František (referee) ; Čučka, Milan (advisor)
First two chapters of this paper deals with the division of optical fiber sensors, digital signal processing and includes price comparison of four experimental sensors. In chapter three analysis, description and evaluation of measurment has been demonstrated on Mach - Zehnder interferometer. Last chapter is about application for signal analysis from vibration sensors. Description contains snippets from source code and graphical user interface. This paper includes three fields - fiber optics, digital signal processing and creation of application - and thanks to them it provides solid basis for study of optic fiber sensors.

Optimization of lubrication system for lubrication of rolling mill bearings
Sikora, Vojtěch ; Blata, Jan (referee) ; Zuth, Daniel (advisor)
The thesis focuses on the optimization of the central lubrication system for the lubrication of rolling bearings of rolling mills in the operation continuous wire rod mill. The work is divided into theoretical and practical part. The first part of the theoretical work is focuses on the search of rolling and tribodiagnostics. The next part focuses on the description of modern central lubrication systems, explanation of their principle and practical use. The practical part explains the function of the old lubrication system for rolling mill bearings with an analysis of its problems. Next is described the technical design of a new central lubrication system, its application into operation and its actual commissioning are described. The last part of the thesis is the conclusion and evaluation of the benefits of the new central lubrication system compared to the old one.

Car Diagnose Using of OBD module
Sikora, Vojtěch ; Volf, Jaromír (advisor) ; Novák, Viktor (referee)
This thesis deals with the OBD diagnostics, their historical development and current trends. The thesis describes individual technical solutions and principles of their function. There is also a list of devices for testing. The thesis includes economic importance and a simple market research. Then it continues with the testing of the diagnostics itself and of a mobile application. Diagnostics VAG-COM was tested using a personal computer and Diagnostics ELM 327 Modul 1 with an application DashCommand that communicates via WiFi with a smart phone. Everything was done with a Skoda Fabia 1.2HTP with 47kW of power. Testing of the program and application can be a beneficial to the reader, because selected procedures are explained in detail.
