Chaos, šílenství a jejich souvislost s prostředím ve vybraných povídkách Edgara Allana Poea
FEKETOVÁ, Petra
Chaos and madness belong among the most prominent themes in the work of the American writer Edgar Allan Poe. For this thesis, I have decided to focus on these two themes and their relation to the settings which they take place in, mainly because the settings are a key feature in Poe's work. The connection of chaos and madness to the settings will be examined through four selected texts from the author's prosaic work. The aim of this thesis is to analyze these texts on the basis of these connections and therefore to provide new points of view on them.

Design and implementation of managed PoE injector
Frkal, Pavel ; Frolka, Jakub (referee) ; Krajsa, Ondřej (advisor)
This study deals with power supply for network devices using existing structured cabling. Various power supplies are analysed including their limitations and also deals with measuring of the consumed energy. The outcome is 24-port passive PoE injector for remote power supply of network equipment. It's suitable namely for remote devices which lacks built-in PoE support as these do not need major modifications (using passive injection). Power options including current measurement may be done via administrative web interface.

Simple Remote Signalling of PLC Systems
Kacálek, Jan ; Šimek, Václav (referee) ; Tříska, Vít (advisor)
The aim of this thesis is the design and manufacture of hardware and software facilities used for the demonstration of communication with PLC systems. Furthermore, this paper summarizes the possibilities of communication and partially implements the MODBUS protocol via RS485 serial line. The hardware device is fabricated on the PCB and the components commonly available in electronics stores. Includes LCD display and LEDs for status display PLC system. The software application is written in Java and implements the same functionality as the hardware device.

Weather Station with Ethernet Interface
Novák, Pavel ; Šimek, Václav (referee) ; Bartoš, Pavel (advisor)
This thesis deals with the design and construction of the meteorological station. The meteorological station is designed and constructed to be able to measure the basic meteorological parameters (temperature, humidity, air pressure) and the other three variables (measuring rainfall, wind speed, wind direction). This thesis will introduce you to meteorology. Meteorology determines the daily weather forecast and the results are used for examples in aviation or maritime affairs. The method of atmospheric origin is given in the theoretical part. Meteorology must use measuring instruments to determine quantities. The dissertation also includes analysis of the measuring instruments. The meteorological station uses the Ethernet technology. In the chapter devoted to Ethernet are described its principles, types and method of power supply over Ethernet. The following section describes the design of the entire meteorological station, selection of all components and description of their connection. The chapter about implementation contains a description of the parts which forms program part of the meteorological station. The aim of the thesis is a summary of the achieved results including price comparison of the renovated meteorological station with other meteorological stations, which can be normally bought.

Network design support software
Špidla, Aleš ; Jeřábek, Jan (referee) ; Pelka, Tomáš (advisor)
The bachelor thesis is aimed at supporting of designing of computer networks. The thesis describes the steps which follows to successful propose of computer network. Furthermore, it discusses errors which should be avoided, the various recommendations from the positioning of devices in the patch panel, to allocating the address space of IP addresses. There is also mentioned three level hierarchy of networks, QoS, problems of VLANs and switches cascade connection. A large part describes the benefits of stackable switches, their inclusion in the network, and then describes the advantages of different kinds of PoE (Power over Ethernet) devices. Also noteworthy is the chapter, which deals with IP networks. It points out how to allocate IP addresses and it also describing the most frequently used method for allocating subnets which is reverse binary method. The last part is devoted to the description of the application, which allows users to learn about different variants of switches, VoIP phones, find out the advantages and disadvantages of different transmission media, or the difference between software or hardware firewall. The output of this application is form, which can serve as network documentation.

Effectivity evaluation of social-preventive program 5P in the Czech republic and its development
BŘÍZOVÁ, Bohdana
The theoretical outcomes of the mentoring program BBBS and subsequently also the solutions of the program 5 P in the Czech Republic are introduced in the theoretical part of the dissertation work. Furthermore the author summarizes the principles of the program and explains the management of the work with the volunteers. She also focuses on the relationship between a child and a volunteer, its typology and its development. The last but not the least the author addresses the evaluation method for BBBS/5 P which is called the Program Based Outcome Evaluation (POE). Furthermore the author fulfills the four selected goals in the research part of the work. The first goal is focused on the modification of the original evaluation method POE and its adaptation for the Czech socio-cultural circumstances. The second goal is the analyses of the current state of the realization of the program 5 P in the Czech Republic with the focus on the registration of the program as the social service. The third very important goal is to evaluate the general trends of the effectiveness of the program by the means of the statistical analysis of the results of the evaluation method POE. The last goal is the development of the new or the adaptation of the current specialized and methodological materials for 5 P.

Charles Baudelaire Translator of Edgar Allan Poe
VACOVSKÁ, Marta
This diploma thesis is focused on the topic of Ch. Baudelaire?s translations of E. A. Poe?s work. The main aim is to show the similarities of these translations and differences between them. It was achieved by using the methods of comparative analysis of the original and the target texts. The motives which led Baudelaire to choose Poe and his work represent the significant role. Last but not least the author reflects the question of Poe?s influence on the work of Baudelaire. The results of the research were achieved with the help of specialised literature, original English texts and their French translations which constitute the basis of the comparative analysis.
