Localization of RF transmiter
Mikuláštík, Jiří ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
The thesis deal with possibility of localization of avalanche victims. Main focus is for RF avalanche beacons. The major objects of this thesis are design and construction of this device. A large part of thesis describes design of avalanche beacon and particular steps of realization. The design take into account the compatibility with commercial beacons. The paramters of designed device are verified by testing and measurement.

The risk of avalanches and rescue operations
Šimčíková, Jana ; Mika, Otakar Jiří (referee) ; Hudec, František (advisor)
This bachelor thesis deals with the risk of avalanches and rescue operations. The risk of avalanches, avalanche occurances, snowpack and snow layers are introduced. Thereafter preventative measures to mitigate the risk of avalanches with tests of hardness and stability of snowpack are described. Also covered is the monitoring and forecasting of risk of avalanches and avalanche danger rating. Information about avalanche rescue is listed in the conclusion.

Security and Performance Analysis of Avalanche Distributed Consensus Protocol
Sapák, Filip ; Malinka, Kamil (referee) ; Perešíni, Martin (advisor)
V tejto práci sme sa zaoberali analýzou "Proof-of-Stake (PoS) distribuovaného konsenzuálneho protokolu Avalanche, problematikou blockchainu, konsenzuálnych algoritmov a simulačnými nástrojmi určenými na simuláciu blockchainu. Po oboznámení sa so všetkými potrebnými skutočnosťami, práca pokračuje implementáciou simulátora konsenzuálneho algoritmu implementovaného v protokole Avalanche, ktorý napodobňuje fungovanie Avalanche konsenzu. Experimenty so simulátorom boli vykonané s rôznymi parametrami a pomohli nám pochopiť vlastnosti Avalanche.

Literature research of resources used in avalanche problems
Besser, Kryštof ; Mašek, Michal (advisor) ; Sovák, Libor (referee)
Title: Current state of active rescue equipment used to prevent snow avalanches. Objectives: The goal of the bachelor thesis is to compare currently available active rescue devices used in a mountain environment Methods: The methods used in my bachelor thesis to obtain the necessary information on active rescue devices were research and study of the literature and its subsequent segregation, together with informal guided interviews with experts who deal with this issue (HS members) and subsequent analysis of the issue. Comparison of the information sought is used as an additional method. Results: There are currently 14 avalanche backpack and avalanche vest systems available on the market. There are currently 10 types of cartridge systems and the remaining 4 are electric systems. As a result of my bachelor thesis I have prepared a comprehensive table with all currently available systems and all necessary information. Keywords: snow avalanche, airbags, avalanche airbag, avalanche hazard, active rescue equipment.

Development and present situation of Mountain rescue service
Táborská, Barbora ; Fiala, Miloš (advisor) ; Vilášek, Josef (referee)
Title: Development and present situation of Mountain Rescue Services Objectives: The main goal of the bachelor thesis is to give an overview about historical development of Mountain Rescue Services in Czech Republic and to depict the most important milestones, which influenced the following events. In detailed way will be outlined the activity of Mountain Rescue Services at present time. Methods: For the bachelor thesis will be used collecting, sorting and interpreting of information. Based on exploration of facts will be reached the goal, which was set for this thesis. Results: Results of thesis confirm the longtime tradition and rich experiences of Mountain Rescue Services in Czech Republic, what became as a good base for functioning of organisation at present. It can be said that members of Mountain Rescue Services are ready and equipped to provide rescue under all conditions. On the other hand provided services could be more supported by law and utilized in term of Integrated Rescue System. Keywords: First aid, Cynology, Avalanche, Mountaineering, Integrated Rescue System

Avalanche monitoring and run-out modelling using GIS
Biskupič, Marek ; Matějíček, Luboš (advisor) ; Hreško, Juraj (referee) ; Škvarenina, Jaroslav (referee)
Snow avalanches a natural phenomenon typical for snowy winter mountains consist of snow and sometimes of other material (debris, rocks, truncated trees and soil). On first sight they seem to be harmless mass of snow sliding down on a slope. But not they can be disastrous. Despite the snow avalanches event lasts for couple of seconds, they can take human lives, and destroy infrastructure. Until they occur in far and remote places they are not concern. The avalanche run- out has been always an issue. How far avalanches can travel? Is there avalanche activity out there? How large is the avalanche hazard on certain places? Will the avalanche airbag will influence the probability of not being critically buried by an avalanche. These are the question the thesis attempt to solve with the use of GIS, remote sensing and statistical analysis. The aim of the thesis was to find reasonable answers to these questions. The effectiveness of avalanche airbags was first tested by pilot study when the artificial avalanche was triggered and motion of the dummies with different types was recorded. Additional estimation of impact forces, speed and final position of dummies was investigated and modelled (publication 6). The mechanism behind the avalanche airbags - inverse segregation was proofed to work in field test, but how is...

The morphology and activity of selected avalanche paths in the Hrubý Jeseník Mts. and the Králický Sněžník Mts.
Krause, David
The occurrence of avalanche paths is usually frequent in alpine environment, but it is also present in mid-mountains such as the High Sudetes. The submitted master thesis is focused on avalanche paths in the Eastern High Sudetes. The morphometric analysis of 8 paths was accomplished to determine their characteristics and comparison with statistical verification. The dendrogeomorphological analysis and further geomorphological mapping was performed in 2 selected paths (Sněžná kotlina and Králický Sněžník) to cover their avalanche activity frequency and to find relationship between their activity and morphology. The results of this study show that there is a strong difference between two groups of avalanche paths in the Eastern High Sudetes. The Sněžná kotlina and The Králický Sněžník avalanche paths are longer and narrower than the other paths. They also have higher elevation difference. The comparison of these two paths performed by dendrogeomorphology indicates higher avalanche activity frequency in the Sněžná kotlina path, which was strengthened after strong avalanche event in 2004. It is assumed that the Sněžná kotlina path contains advanced avalanche landform, which is a long gully, probably also affected by debris- flows in the past. On the other hand the Králický Sněžník path is rather less...

Basic summary knowledge of the objective mountains hazards in freeride skiing users
Preininger, Kryštof ; Jindra, Matouš (advisor) ; Chrástková, Martina (referee)
Title: Basic summary knowledge of the objective mountain hazards in freeride skiing users. Objectives: The aim of this work is to create an overview of theoretical knowledge of objective mountain hazards for freeride skiing users. Methods: I used the search method, exploration and analysis of the obtained information, which is related to the objective danger of the mountains. Results: The result of this work is to create an overview of the knowledge needed before riding in the open terrain, which should help in the movement in the open terrain and to prevent dangerous situations. Keywords: avalanche, terrain, weather
