Design of reliable enterprise networks with service quality support
Kiška, Martin ; Koutný, Martin (referee) ; Novotný, Vít (advisor)
This work deals with creating a reliable corporate network and its variety capabilities against loops and supporting QoS on link and network layer. On the basis of theoretical knowledge is designed an experimental network in the laboratory of Institute of Telecommunications composed of several computers, VoIP pohones, switches and routers. Functinonal network is then tested to failure of individual nodes and the impact on network traffic. In another part of this bachelor thesis this network is tested using different QoS support options.

Uninterruptible Supply of the Hospital Information System
Kučera, Josef ; Sekora, Jiří (referee) ; Fedra, Petr (advisor)
This bachelor thesis is focused on the proposal for an appropriate source of uninterruptible power supply (UPS) to the school server UBMI where is currently installed HIS (hospital information system) CLINICOM Corporate SMS. UPS should have ensure the protection of data being unfinished, secure off site and to inform the line voltage failure.

Uninterruptible Power Supply
Mrázek, Petr ; Harabiš, Vratislav (referee) ; Chmelař, Milan (advisor)
The thesis deals with Uninterruptible Power Supply (UPS) and associated problems of backup power in case of unexpected outages of electricity. Start of work is dedicated to limitation of the electricity supplies, as well as their causes and consequences. Furthermore, brief history of UPS and subsequently distinguish between UPS’s architectures. There is also a description of the energy sources such as batteries, flywheels or fuel cells. Part of thesis describes security of electricity supply in health care facilities, including requirements for emergency power. The own design of UPS is described in the end.

FLATcon system – flat control system with RF communication
Krivoklatský, Filip ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
This bachelor’s thesis discusses solutions of smart houses. It presents some of the available solutions on market and points out its positives and negatives. The thesis itself focuses on solutions which support wireless communication. Subsequently, the design of custom solution named FLATcon is being proposed. It includes designing of central unit, which is the main part of the system. First, the hardware part is being designed. Base of this is minicomputer Raspberry Pi 3 B with necessary inputs and outputs. Uninterruptible power supply and wireless communication interface are also part of the design. Subsequently, thesis focuses on control software design and on user interface in form of web server. At the end of this thesis, achieved results are presented.

DC to DC inverter for backup power supplies
Eliáš, Marek ; Zemánek, Miroslav (referee) ; Boušek, Jaroslav (advisor)
This thesis deals with the design of a DC/DC converter designed for charging supercapacitors from the 36 V voltage source and consequent back transformation of supercapacitors voltage to the required output voltage. In the thesis the designs of decreasing and increasing DC/DC converters including schematics and calculations of individual components are presented and described. The calculations necessary for the supercapacitors to meet the 10Wh energy condition and the voltage balancer on the capacitors are given below. Completely designed equipment will be assembled and tested on supercapacitors with lower energy.

Uninterruptible power supply
Podal, Pavel ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
The objective of this work is to inform readers on classification of Uninterruptible Power Supply (UPS). depending on the equipment for which is to be used. Voltage quality has a decisive influence on the operation of equipment. There are various common power problems that UPS units are used to eliminate. Furthermore, I described backup power sources of energy used for UPS, in partikular secondary battery. This text is about UPS technology used for critical applications, witch must not fail due to a power outage or other power anomalies too.
