Improvement of Bit Error Rate in Free Space Optical Link
Novák, Marek
The article describes an inovative bit error rate reduction technique principle and its practical implementation. The design is implemented in an FPGA and can be combined with other more conventional BER reduction techniques. The presented approach benefits from properties of an optical channel which a general RF channel does not have.

Test Management Tool
Novák, Miroslav ; Janoušek, Vladimír (referee) ; Smrčka, Aleš (advisor)
The aim of this thesis is to specify, design and implement a test management tool that will work both on its own and on the Testos platform. The problem was solved by creating a client web application and implementing a web service using the REST API, which ensures interoperability with other tools. The created system allows to manage the basic testing process, which consists of project management, test requirements management, test library management and management of individual testing runs.

Intersection Úvoz (street) x Údolní (street in Brno city)
Pagač, Aleš ; Novák, Martin (referee) ; Všetečka, Martin (advisor)
He subject of this bachelor thesis is designing a modification for intersection between Uvoz street and Udolni street. The goal is the enhancement of public transport connection and pedestrian movement. This design should not worsen the fluence of transport in any way. My main focus are station locations and traffic lanes. The fluence of transport is handled by traffic lights coordination. Finally, I've selected just one from multiple solutions.

Automatic testing of gas leak detector
Skryja, Petr ; Malinowski, Radim (referee) ; Novák, Marek (advisor)
This work deals with the automatic testing of an ultrasonic gas leak detector, which has to be tested during normal changes in the development phase. The reader will be acquainted with the basic principles of gas detection, design of the test product, software architecture its implementation. The following is a presentation of the application and instructions for writing tests. In this work, the Beaglebone Black development board with the Debian operating system is used as the core of the entire test product.

Intersection of highway I/42 and path along Svitava (river)
Dušek, Martin ; Novák, Martin (referee) ; Všetečka, Martin (advisor)
The bachelor thesis project deals with the problematic part of bycicle path along Svitava river, around the crossing with Hladíkova street. A safe pedestrian crossing for a path frequented by cyclists, skaters and pedestrians is missing, which results in unsafe crossings of busy four-lane road l/42. The bycicle path in the project is designed on the west side of the river under the road bridge to avoid any kind of contact between the cyclists/skaters/pedestrians with road l/42 and to ensure the fastest and safest possible transit of both cyclists and cars. Emphasis was put on the stability of construction in precipice, tolerance of the construction against water and effective longitudinal slope and length of path ratio, to ensure safe concurrent passage of both cyclists and pedestrians.

Using the Concept of Total Compensation in the Selected Subject
Ziminová, Monika ; Novák, Miloš (referee) ; Kruntorádová, Markéta (advisor)
The bachelor thesis focuses on the usage of the Concept of Total Compensation in the subject of Marcela Cisarova. The theoretical part explains basic concepts related to the topic. Practical part of the thesis introduces Marcela Cisarova and includes the analysis of an economic situation as well as the analysis of external environment. In the result practical part creates an effective motivation program with a goal of increasing work efficiency of employees.

Examples of drive control with frequency convertor Sinamics S120
Novák, Michal ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
In this thesis is described a laboratory process of example of traction control with frequency converter SINAMICS S120. The focus of this thesis is divided into three parts. Modification of the traction to translational motion for transport of the open vessel with liquid. Proposal of the autonomous operation of the traction without connection to other devices such as a personal computer or PLC, including wiring diagram. The simulation of a dynamic movement for transport of the vessel with liquid in the simulation environment MATLAB and implementation using the proposed laboratory traction. Commissioning and activation of each control functions is described step by step.

FSO transceiver for link quality estimation
Novák, Marek ; Vlček, Čestmír (referee) ; Wilfert, Otakar (advisor)
Tato diplomová práce pojednává o zmírnění bitové chybovosti bezkabelového optického spoje s užitím principu reciprocity aplikovaného na komunikační kanál, spolu s možností kódování přenášených dat. V této práci je implementováno LDPC a Reed-Solomonovo kódování pro jejich vyhovující vlastnosti. Zbytková rámcová chybovost je vypočtena a k dispozici jako výstup systému, který je implementovaný v hradlovém poli (FPGA).
