Educational PocketQube Satellite Demonstrator
Veverka, Jiří ; Povalač, Aleš ; Jaššo, Kamil
This paper presents the design of a 2P (50×50×50mm) PocketQube satellite which will be used in STEM laboratory classes. The proposed system was designed with emphasis on modularity, ease of replacement using commercial off-the-shelf components, and easy understanding of the subsystems one can find in a satellite of this type. It also encourages students to come up with their own ideas and modules. The satellite itself is made out of four main modules: On-Board Computer, Communication module, Electric Power System module, and Payload module. These four modules are encapsulated in a structure made entirely out of PCBs and together form the basis of the satellite.

FROM THE END
Krausová, Radana ; Čapek, Jan (referee) ; Tobola, Ondřej (advisor)
The bachelor thesis focuses on designing a cover for a multisensor fire alarm. The project originated in collaboration with the company LITES, which specified the requirements for the alarm cover. The main objective is to create a product suitable for various interior types and capable of integration with other end elements in the space. The design is conceived for installing the alarm either directly on the ceiling or for recessing it into the ceiling. Manufacturers and sellers of these devices are increasingly recognizing the importance of visual communication in the user interface of fire alarms. If the end element is too conspicuous or detracts from the overall impression of the room, it can evoke considerable aversion from the user. The work is based on simple geometric shapes such as cubes, spheres, and cylinders, and their subsequent perforation. This decision stemmed from the effort to streamline the shape of the cover from unnecessary elements. For the alarm design, I chose the shape of a cylinder, which best meets the requirements for installing the alarm and its function in the space. In my opinion, it is important to perceive the alarm as an accessory in the space, not just as a technical element. This idea significantly changes the approach to the product and therefore also the approach to its design.

Creation of Documentation for construction of power and data wiring for a historical and a listed building
Nestrojil, Martin ; Janík, Daniel (referee) ; Bátora, Branislav (advisor)
This thesis is describing DPS power and data circuits installations for a historical listed building. Firstly, the theory describes requirements for architects and designs, the types of designs, the laws and directives. This part also contains instructions on how to lay the circuits, how to create environmental report and other topics closely related to design and architecture. Secondly, there is description of the design of the power and data installations for the building. The third practical section contains full project design documentation for power and data circuits for this building including technical drawing, environmental report, ground plans of the building, drawings of switchboards and block drawings. The outcome of this report is to present the theory and then create all relevant documentation for this historical building.

The impact of executing new thermal insulation on a apartment building on the expenses associated with its operation
Machová, Petra ; Kosová, Jaroslava (referee) ; Čech, Josef (advisor)
The topic of the diploma thesis „The impact of executing new thermal insulation on a apartment building on the expenses associated with its operation “ is a draft and appraisal of four variants of thermal insulation of the building. The thesis deals with the assessment of the current proposal for apartment building envelopes along with proposing alternative plans with emphasis on reducing heating costs. The first section describes the types of buildings according to heating demand and a list of different variants of thermal insulation materials. The second part is devoted to a specific apartment building in the Ústí nad Labem for which there are designed in four variants of insulation. The work includes thermal assessment in original condition and the assessment of new condition modified by adding thermal insulation. Through research will bedetermined price of implementation of proposed insulation options together with the costs of operation of the apartment building. In conclusion, the diploma thesis evaluates the payback period of insulation.

5G Cellular Networks
Schaller, Lukáš ; Novotný, Vít (referee) ; Krkoš, Radko (advisor)
The subject of the bachelor’s thesis is mobile communication network of 5𝑡ℎ generation with focus on improvements from current 4𝑡ℎ generation. At the beginning of my work I summarized the system of 4𝑡ℎ generation mobile network EPS including description of individual parts. Next section pays attention to 5𝑡ℎ generation mobile communication network in context of network demands and future development, radio interface, network architecture or Internet of Things. Next follows solution of D2D communication especially LTE Direct and Wi-Fi Direct technologies. Here I paid attention to data agregation used in conjunction with Internet of Things enabling usage of IEEE 802.11 or IEEE 802.15.x standards. In closing part I described heterogeneous radio network and in particular mutual integration of cellular and Wi-Fi networks. In the first practical part of my bachelor’s thesis I measured parameters of Wi-Fi network during client-server communication. In the second practical part I tested data agregation of two devices using experimental network at Institute of communication.

Accommodation facility
Šindlář, Josef ; Utíkal, Aleš (referee) ; Utíkalová, Ivana (advisor)
The subject of this master thesis is a project for the construction of accommodation facility with a basement. The building is located in Ostrava close to the historical centre of the city. The building is a 4starcategory accommodation facility and will serve as temporary accommodation. There will be a restaurant and a gym designed for hotel guests only. The accommodation capacity is 68 guests. A car park for hotel visitors is situated close to the hotel. It is a brick structure made of sand-lime blocks,monolithic ceilings and a first underground floor. The building is insulated with ETICS system. Paste-like plaster and brick tapes were used for facade construction. The roof is made up of one roof surface and the foundation will be realized on the foundation strips. The building is situated on flat terrain. The project was developed in ArchiCad21, AutoCad 2016 and SketchUp.

Analysis of control procedures in 4th generation mobile networks
Schaller, Lukáš ; Zeman, Václav (referee) ; Novotný, Vít (advisor)
The subject of the diploma thesis are procedures in EPS network related to the operation of mobile terminals. In the introduction of my work I described the EPS system, including the quality of services and bearers. The following section focuses on control procedures in the EPS system such as attach network procedure, detach procedure, service request, handover or tracking area procedure. Further, three technologies for Internet of Things were described, namely EC-GSM-IoT, LTE-M and NB-IoT. All the procedures mentioned above were also captured in the experimental VUT EPS network and analyzed by TravelHawk using software M5 and Wireshark. Theoretical and practical findings were subsequently used out for setting of laboratory task for subject MKPM.
