Picobaloon s využitím low-power bezdrátových sítí
Kudera, Matěj ; Peringer, Petr (referee) ; Janoušek, Vladimír (advisor)
Aim of this master thesis was to create a small meteorological probe (PicoBaloon) which can record its position and basic meteorological information. Information recorded by this probe has to be transmitted to the user so it can be evaluated. Theoretical portion of this work describes how to create this type of device and which technologies can be used for its implementation. Next, information describing what exactly PicoBaloon is are presented, which are then used to form requirements for this system. Based on described technologies and system requirements final system design was created. Created system consists of two parts. First part is the probe itself which is created on its own piece of printed circuit board. Probe is controlled by a small microcontroller and consists of components that can generate power with a small solar panel, determine its position with GPS, record meteorological information and send recorded information to the user with wireless technology. Second part of the created system is a web application which presents recorded data to the user. At the end of this thesis physical creation and testing of this system is described.

Mathematical models of military conflicts
Skopal, Martin ; Potůček, Radovan (referee) ; Čermák, Jan (advisor)
This thesis discusses the mathematical models used in the theory of warfare. The aim is to build and describe the Richardson model of conict and selected Lanchester models of combat. The models are subsequently analysed with a focus on stability. A part of the thesis is also formed by application of real data onto the models and by the subsequent evaluation of their results.

Elimination of Discontinuity Supply of Electric Energy from Renewable Energy Sources
Radil, Lukáš ; Goňo, Radomír (referee) ; Braciník, Peter (referee) ; Mastný, Petr (advisor)
Doctoral thesis deals with domain of electric energy storage. It seeks to define the methods of accumulation, which can be used in industrial applications and define the conditions for the use of storage systems in electric power systems with extended penetration of renewable energy sources. In the context of current developments in this field is analyzed detail one of the perspective storage systems - Vanadium Redox Battery (VRB). One of the outcomes of this work is economic and energy analysis of storage systems, which are conceived with a disproportion between production and consumption of energy. The work was supported by the Centre for Research and Utilization of Renewable Energy (CVVOZE) no. CZ.1.05/2.1.00/01.0014 and research project no. FEKT S-11-9.

Measurement of Backbone Routing Parameters
Celárek, Ondřej ; Kořenek, Jan (referee) ; Matoušek, Jiří (advisor)
This thesis deals with issue of routing between Autonomous Systems. For routing between autonomous systems is used Border Gateway Protocol (BGP). The routers in Autonomous Systems modify their routing tables based on BGP messages. Routing tables are used for forwarding information on Internet. Issue of this thesis is analysis of change routing tables for eventually optimizing of routing architecture. First part of thesis is focused on theory of routers, routing ang BGP. Second part of this thesis focuses on implementation and execution experiments with routing tables. In this part are also described reached results.

Predicting Trajectories of Vehicles and Pedestrians for Driving Assistent Systems
Mudroň, Marek ; Musil, Petr (referee) ; Smrž, Pavel (advisor)
This bachelor thesis deals with representation of a traffic scene by processing monocular video sequence. I try to predict a trajectory of detected vehicles in a short time horizon, based on created representation. Current approaches use multiple expensive sensors to gather instant information of environment. In the thesis I introduce technique, which is able to extract data from an environment by image processing techniques without the need of expensive sensors. The result of this work is a system creating opportunity to reduce the sensor costs of a system for scene representation and trajectory prediction of vehicles in the scene. In addition, comparison of models trained on differently processed data is provided, as well as data about how my system approximates the most reliable prediction models.

Civil Applications of Autonomous Systems: Implications for the Military Sector
Fortunati, Lorenza ; Solovyeva, Anzhelika (advisor) ; Nikolić, Luka (referee)
This thesis aims to examine the growing development of autonomous systems from a civilian and military perspective. The literature analysis has shown that in the military sector there is much access to an interactional-scientific and literary debate, especially on the growing possibility of autonomous weapons development. On the other hand, however, the civilian sector is increasingly advancing the development of autonomous systems. Many of these are already being applied in civilian society: from self-driving cars to medical equipment. Nonetheless, the study showed that although these sectors are going at different speeds, the risks and challenges related to the topic of autonomous machines are very similar, especially with regard to the concept of responsibility and human-machine nexus. For this reason, this thesis aims to analyze the civilian experience in the field of autonomy to determine whether there might be any transferable lessons from the civilian to the military world for the future development of autonomous weapons. After a thorough analysis of the aircraft crashes involving the Boeing 737 MAX and the accidents caused by the self-driving cars, this thesis concludes that the best way to address the ethical and moral challenges of autonomous weapons is to develop and design such systems...

Enrichment of IP Flow Records with Data from External Sources
Zvara, Adam ; Uhříček, Daniel (referee) ; Žádník, Martin (advisor)
This thesis addresses the enhancement of network flows from the viewpoint of a collector, obtained through NetFlow/IPFIX monitoring architecture. The primary objective is to extend the IPFIXcol2 collector with interfaces that can be utilized to develop new modules capable of enriching network flows. The proposed approach involves designing and implementing two modules, namely ASN and GeoIP, to enrich flows with information related to autonomous system numbers and geolocation. After implementing these modules, performance evaluations are conducted to assess their impact on the collector’s overall efficiency.

Routing policies and real paths in the Internet
Hlaváček, Tomáš ; Peterka, Jiří (advisor) ; Kruliš, Martin (referee)
Routing policies are now represented by RPSL and by its evolutionary extension called RPSLng. These languages can be used for describing unique routing policy of each autonomous system. Experience shows that even though there are translation tools from RPSL and RPSLng to configuration formats of commonly used routers, the actual network configuration is rarely generated from RPSL sources and routing policy is then perceived as marginal paperwork, which often does not reflect the real network settings. There will be most likely a need for RPSL format change in order to remedy the discrepancies. To support this I present long-term measurements of inaccuracies in routing policies compared to real paths in the Internet. I also present a list of the most frequent problems, and I offer suggestions, how to reform RPSL to improve situation in the long term. Powered by TCPDF (www.tcpdf.org)
