Control of HVAC equipments
Zaoralová, Kateřina ; Weiglhofer,, Willy (referee) ; Rubina, Aleš (advisor)
The aim of the diploma thesis is application of the topic Control of HVAC equipments. The thesis is divided into three part – A, B, C. The first theoretical part deals with controlling/regulation in general, it focuses on controlling/regulation of HVAC equipments and it describes ways of air volume flow measurement, which relates to the third experimental part. The second part is focused on design of HVAC system in inpatient ward and fit-out for employees. In the third part was realized verification of air flow volume controller in two chosen buildings, whence in one there weren´t fulfilled manufacturer´s requirements and in the second one they were fulfilled. In conclusion there were compared measured values.

Innovating a laboratory task: Inspection of electrical wiring and devices
Klement, Petr ; Steinbauer, Miloslav (referee) ; Kadlec, Radim (advisor)
The bachelor thesis deals with the innovation of laboratory tasks, called Inspection of Installation and Equipment. The aim is to construct a device that will be able to simulate errors during the inspection on the appliance. The task will be extended to build the appliance itself, which will be measured and further simulated errors. The REVEXprofi digital measuring instrument will be used for measurement. The safety of the device will be ensured by the measuring properties of the REVEXprofi instrument, by storing the circuit inside the built-in device and by the small overlaps of the measured values above the standard when the error is triggered. The circuit was simulated using the TINA 9.0 program.

Diagnostics of semiconductors properties
Šeliga, Ladislav ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This thesis describes the basic properties of semiconductor materials and methods of their measuring. In the first part of this work are discussed elemental semiconductors, semiconductor compounds and the band structure. The next section describes current conduction in semiconductors, methods for measuring resistivity. This work is focused on the measuring drift mobility of minority charge carriers using the Haynes-Shockley method for a sample of silicon semiconductor, the creation of automated workplace in the development environment VEE Pro and resistivity measurements of silicon samples.

Optimization and parameter measurement of PON network FTTX
Černý, Michal ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
Práce rozebírá současný vývoj na poli pasivních optických sítí a jednotlivé generace přenosových standardů. Podrobněji se zabývá parametry ODN, metodami jejich měření a volbou potřebných měření v praxi. Hlavní část práce je zaměřena na měření pasivního WDM prvku, kde je provedena analýza vstupů a výstupů, měření vložného útlumu a přelechů podle ORL na provozních vlnových délkách.

Differential electromagnetic analysis
Novotný, Bohumil ; Člupek, Vlastimil (referee) ; Martinásek, Zdeněk (advisor)
This diploma thesis studies the theory side channels, simple and differential analysis, and types of attacks on the side channel, which may be run against the cryptographic system. The thesis explains the principles of side channel attack on a possible defense against them. The second part of the thesis describes experimental work created, its individual components and their functions. The findings builds custom solutions attack the electromagnetic side channel using electromagnetic probes and the workplace equipment developed for this task. The final part of the thesis is devoted to the description of the implemented algorithm, a description of measurement, measurement results and possible modifications of algorithms implemented in the microcontroller for full automation of the attack on the device, against which the attack was conducted.

Measuring methods of key parameters in optical networks
Balon, Jiří ; Reichert, Pavel (referee) ; Tejkal, Vladimír (advisor)
The main goal of the master’s thesis was to familiarize with optical networks dilemma and its measuring during fabrication. The whole thesis is divided into several parts where the first part deals with optic fiber dilemma. It describes its kinds, properties and also suggests a basic principle of optic signal dispersion using these fibers. It describes also optical network FTTx architecture (Fiber To The x). The second part of the thesis focuses on methods of measuring key parameters of optical networks. Is brings out the methods of measuring optical loss and dispersive influences. The last and final part in focused on creating a methodical manual for measuring these networks during its fabrication and verifying measuring methods stated in the theoretical part inside a real network. Measuring was implemented on an optical network of Masaryk University in Brno.

Spectral characteristics measurement of single fibre optical transmission
Balon, Radek ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The main object of the bachelor´s thesis is show familiarize with optical networks and measuring when the fibres are connected to operating network. The whole thesis was separated into several parts. The first part was deals with optic fiber and properties, kinds of optic fibers, methods of propagation light inside fiber and important parameters, which has undesirable effects, such as optic loss and dispesive influences. Next part was concentrated on transfer technologies, which where used for data transmission in operating networks. We talked about differences between technologies and describe the monitoring system, which was used for measuring parameters in operating network. The last part was focused on own measuring. We was measured the parameters in operating network CESNET2 and influence of the signal after connect optic monitoring probe. Measuring was implemented on optical network of Masaryk University in Brno (ÚVT MU).

Emotional intelligence and approaches to its cognition and measurement
Tarasenko, Sabina ; Boukalová, Hedvika (advisor) ; Niederlová, Markéta (referee)
The purpose of this study is to provide an overview of the development of the concept of emotional intelligence, the most important concepts dealing with this topic and the methods used for its recognition and measurement, which are associated with models. For better orientation in the topic, the concept of emotions and emotional intelligence applied in selected fields is also explained and defined. In the empirical part, the research is designed to create measurement methods of emotional intelligence, which utilizes the integrated model and combines the self-assessment questionnaires from more models with FACS and MSCEIT. Research should, on a large stratified sample, show, if the newly created method validly measures the level of emotional intelligence through parallel validation of the MSCEIT. Finally, it describes the possibilities of using the method and the actual outcome, expressed with the emotional quotient, in practice.
