Environment mapping
Juriga, Jakub ; Pavlík, Jan (referee) ; Bilík, Martin (advisor)
This bachelor thesis deals with various possibilities and methods that are available for studying especially of underwater environment. After comparing of the various methods, it is focused mainly on sonars and echolots from their history through their artition by type / kind of broadcast signal, kind of ray and possibilities of the resulting image display, to the different methods of reading of the image and the ability to analyze it properly. In the next part thesis, the attention is dedicated to the application of these technologies in different detection systems, due to the correct understanding of the detection, the principle of operation of the input signal and the gradual transfer to the resulting image suitable for further processing are described. In the conclusion, the already used distinguishing methods are described and also their potential future use.

Monitoring of persons in an enclosed space
Rivolová, Kristýna ; Kolářová, Jana (referee) ; Sekora, Jiří (advisor)
This diploma thesis deals with monitoring of persons in an enclosed space. The goal of this thesis is to get acquainted with the issue of indoor localization and the subsequent creation of own solution using the ultrasound technology. Ultrasound technology should eliminate some deficiency of current technologies. The theoretical part includes the overview of some current methods. Last part of the thesis verifies the function of device.

Sonar design in Old World bats: patterns of specialisation
Staňková, Markéta ; Horáček, Ivan (advisor) ; Lučan, Radek (referee)
Echolocation ranks among key components of adaptive setting of bats. It enabled them to evolve a plethora of diverse foraging strategies and exploit an enormous spectrum of food resources for which they represent one of the most diversified groups of terrestrial mammals with a cosmopolitan distribution. Evolution of echolocation proceeded via responses to diverse constraints and factors, both intrinsic and extrinsic, that effect particular variables of echolocation biology. The present bachelor surveys, based on literary records, briefly some of these effects and their role upon structure of bat communities. I summarize basic characteristics of echolocation types, influence of Doppler shift, strategy and use of echolocation in different environments and adaptation against defensive abilities of a prey. Among other I provide an account of history and evolution of bat detectors, the instruments essentially improving current study of that topics. Keywords: Bats, echolocation, sonar, diversity, adaptation, Old World

Cable faults detection and layout
Marek, Tomáš ; Skalka, Miroslav (referee) ; Ondrůšek, Čestmír (advisor)
This bachelor´s thesis is focused on tracing cables stored in the ground. Determination of the depth, prelocation of cable defects, determination of exact point of the defect. This thesis gives review of different methods of tracing and prelocation of different types of defects and select the best method for their location. Bachelor´s thesis describes in detail different possibilities of tracing and prelocation of cable defects.
