Verification of PlanetLab servers location
Pružinský, Ján ; Verner, Lukáš (referee) ; Komosný, Dan (advisor)
The main objective of this thesis is to analyze the nodes of PlanetLab network. The analysis is focusing mainly on verifying the availability of nodes and on verifying the physical position of nodes. Individual nodes are tested for availability of ICMP protocol and SSH protocol. Availability of ICMP protocol is verified by using ping program. The main part of the thesis is devoted to verifying the addresses of nodes. Identified addresses are compared with entered addresses and the resulting conformity is evaluated at the level of the state, county, city and streets. Precision of specified address estimation is calculated based on given GPS coordinates. This thesis also deals with the dividing of nodes based on calculated usability index and accuracy index. The theoretical part contains a description of an experimental PlanetLab network and Google Geocoding API.

Position navigation system with GSM interface
Pristach, Marián ; Khatib, Nabhan (referee) ; Kadlec, Jaroslav (advisor)
The objective of the diploma thesis is to design a device for positioning of mobile devices using GPS satellites. When coordinates are acquired they can be sent via the GSM network to a user's cell phone or to an SQL server. A web interface has been designed to access the stored data and to show the current device position and the history. This position datalogging system can be used for monitoring vehicles as well as a security system for cars.

Track's Elevation Profile View on a Public GIS
Doubal, Štěpán ; Šilhavá, Jana (referee) ; Fapšo, Michal (advisor)
This bachelor's thesis describes the design and implementation of a user script for GreaseMonkey (plug-in for Firefox). This script adds a functionality to show height profile of a defined route. The route is defined using public GIS tools from www.mapy.cz. The script extracts coordinates from page DOM structure, processes it and draws a height graph. The graph is created using http://www.heywhatsthat.com/profiler.html [2] or www.profile.hy.cz, which provides height graph drawing using www.vyskopis.cz JavaScript API [4].

Flight initiation distances and life histories in birds: comparison of intra- and interspecific approaches
Brzobohatá, Tereza ; Albrecht, Tomáš (advisor) ; Klvaňa, Petr (referee)
Information about the distance, in which the birds flee from predators, may help us to better understand avian escape behavior and stress responses. These distances are influenced by many life-history traits and related factors, both on intraspecific and interspecific levels. This bachelor's thesis is trying to summarize the current knowledge of agents influencing flight initiation distances (FID) of birds, in the form of a literary research. The first section deals with antipredator behavior in birds, and explains methods that are used for measuring critical distances. In the second part of thesis, factors affecting flight initiation distances on intraspecific level are described. The main emphasis is on impact of age characteristics, body sizes, reproductive investments and geographical distribution. The last chapter summarizes the information about relationships between FID and life-history traits on interspecific level. The age of the individual, levels of stress hormones, the effect of the season and biotop are described in detail. Powered by TCPDF (www.tcpdf.org)

Lipid composition of biological membranes and life-histories in songbirds
Šimonová, Kateřina ; Tomášek, Oldřich (advisor) ; Sam, Kateřina (referee)
Differences in the composition of cell membranes are considered to be the physiological mechanism responsible for different metabolic rates, life span and consequently, different life-histories. The membrane pacemaker theory suggests that higher membrane unsaturation may be an important factor responsible for higher metabolic rate and shorter life span of organisms. The alternative hypothesis, on the other hand, assumes that membranes can function as structural antioxidants, and thus that higher membrane unsaturation may be associated with longer life span. The aim of this work was to test how changes in the fatty acid composition of membranes depends on body size, latitude and altitude, within which different life-histories and metabolic rate were observed. Temperate and tropical lowland songbird species were chosen for the models testing the effect of latitude, and only tropical species of songbirds were chosen for the models testing the effect of altitude. Part of the work was molecular sex determination. Using gas chromatography and mass spectrometry, the amount of individual fatty acids contained in red blood cell phospholipids was obtained from blood samples. The results showed that the composition of the membranes in most cases correlates with body size, which also correlates with almost all...

Free schools and its application on contemporary education
Bartošová, Alexandra ; Poche Kargerová, Jana (advisor) ; Vallin, Petra (referee)
I deal with the democratic school term in my diploma thesis. I clarify the term, I present few of the democratic schools and critical pedagogy. My goal is to highlight the qualities of the democratic school and demonstrate the arguments for considering it as equal and adequate to classical education system. I highlight the importance of attention and financial support from MŠMT for the democratic schools. Few of the democratic schools and the movements were inspired by the concept of independent british boarding Summerhill school and his founder Alexander Sutherland Neill. I will describe pedagogical principles of A. S. Nell and the history of Summerhill school in my thesis. Partial goals are to clarify in what extant and how were employed the principles of Summerhill school in schools in the Czech republic; and how can be the pedagogy of A. S. Neill followed in Czech settings. I will decribe my own point of view on the schooling and teaching. I will compare them to several schools, e.g. Scio school, Ježek bez klece school, Neškola, Sudbury Valley School, Neue Schule etc. after that. I will address the terms unschooling, democracy and boarding school. I employ a method of comparison, analogy, analisis and synthesis.

Relationship between the UV index and selected parameters
Tomanová, Helena ; Pokorná, Lucie (advisor) ; Metelka, Ladislav (referee)
Relationship between the UV index and selected parameters Abstract Ultraviolet radiation (UV radiation) is a shortwave radiation with wavelengths from 100 to 400 nm. This radiation has both positive and negative effects on living organisms and human health. Therefor the so-called UV index (UVI), characterizing the biological effect of UV radiation on human health was defined in 1994. This thesis aims to evaluate the link between selected factors (total ozone column, solar elevation angel, cloudiness and altitude) and the UVI values. Observed data at four stations in Czechia (Hradec Králové, Košetice, Kuchařovice, Labská bouda) and SYNOP reports from the four nearest stations during the period 2010−2017 were used. The Sun elevation (angle of Sun ray) has the strongest effect on the UVI values. The highest UVI values are generally reached at high angels when the Sun rays go the shortest path through the atmosphere. The increase of the UVI is exponential, from an angle of 30ř the increase is approximately linear. The UVI values increase on average by 0.8 at the Hradec Králové station and by 0.9 at the Labská bouda station for angle increasing by 5ř. The effect of clouds is significant and depends on the height and the clouds amount. High level clouds reduce UVI negligible, overcast sky by only 15 %. Medium and...
