Synchronization of measuring devices by optical fibres
Petr, Ondřej ; Šebesta, Jiří (referee) ; Dřínovský, Jiří (advisor)
The aim of this work was to get acquainted with the possibility of transmission of RF signals using optical cables. And design synchronization modules to transmit the reference signal, so that the source and the receiver of the signal are time-synchronized and mutually galvanically separated using optical cable. To transmit and receive optical signals through optical fiber, I chose the transmitter and receiver of the series HBR- 0400 the company Agilent Technologies.

FM receiver and radio data system processing using FPGA
Petr, Ondřej ; Pirochta, Ondřej (referee) ; Maršálek, Roman (advisor)
This term paper is the second part of the dissertation FM RDS signal processing using FPGAs. In the first half of the work is processed the information needed before the actual design and implementation. These can be divided into three themes. The first theme is the received signal VHF / FM + RDS, the second one handles the problem of software radio and last topic concerns FPGAs. The second half deals with the solution implementation and receiver radio VHF / FM and bitrate optional RDS to digital form and its implementation on FPGA. This section also includes the measurement of results.

Inverted Totalitarianism
Petr, Ondřej ; Hauser, Michael (advisor) ; Rybák, David (referee)
This Master's thesis reflects the theory of American political philosopher S. Wolin. The work introduces the reader to interpretations of S. Wolin's term inverted totalitarianism and confronts it with the common and mainstream approaches to totalitarianism. It is concerned about S. Wolin's reflection on contemporary western liberal democracy as managed democracy. The text pays attention to work of G. Agamben who takes a similar critique on the form of Euro-Atlantic democracy; for instance the thesis deals with his view of state of exception in which the author sees connections on inverted totalitarianism.

Intracranial Aneurysms - Treatment Options and Natural Course. Safety and Efficacy of Treatment Strategies for Posterior Inferior Cerebellar Artery Aneurysms.
Petr, Ondřej ; Beneš, Vladimír (advisor) ; Haninec, Pavel (referee) ; Přibáň, Vladimír (referee)
BACKGROUND: Posterior inferior cerebellar artery (PICA) aneurysms are an uncommon, heterogeneous group of aneurysms with poorer neurological outcomes compared to other intracranial aneurysms. At first, as part A, we conducted a systematic review of the literature to evaluate the safety and efficacy of treatment strategies for PICA-aneurysms. Subsequently, as part B, we performed a multicenter retrospective study to analyze the outcome in a large series of patients treated with contemporary microsurgical and endovascular techniques. METHODS: For the meta-analysis, a systematic search of Medline, EMBASE, Scopus and Web of Science was done for studies published through November 2015. We included studies that described treatment of PICA-aneurysms with ≥10 patients. Random-effects meta-analysis was used to pool the following outcomes: complete occlusion, technical success, periprocedural morbidity/mortality, stroke rates, aneurysm recurrence/rebleed, CN-palsies rates, and long-term neurological morbidity/mortality. As the second part, aiming to report the current trends and results in treatment strategies for PICA-aneurysms, records of 94 patients treated for PICA-aneurysms between 2000 and 2015 at 3 large referral neurovascular centers were retrospectively reviewed. RESULTS: In the meta-analysis, we...
