Wireless sensor networks for environmental monitoring
Mizera, Josef ; Červenka, Vladimír (referee) ; Morávek, Patrik (advisor)
his work is focused on usability of wireless sensor networks for monitoring environment. Wireless sensor networks are used more and more for this purposes. This technology has great advantages in comparison with cable networks, mainly in difficulty of their realization. This work contains a description of wireless sensor networks, norms and specifications used for these networks. Requirements on software processing data from sensors and how the signal is distributed. There are examples of applications where wireless networks are used. The reasons why these networks began to be used and in what way they eased the work in such area or problems that are solved by these networks. In the last part of my work is a design of application for monitoring of forest fires in area of Komonec by using wireless sensor networks where it should be beneficial.

Oscillation and wave experiments for Practical Course in School Experiments I
Řehůřek, Michal ; Mandíková, Dana (advisor) ; Koudelková, Věra (referee)
In our thesis we focused on demonstrational-experiment-projections and instructions for mechanical oscillations, waves and acoustics. Nevertheless, we did not marginalize other types of tasks linked to experiments. As a starting point of our thesis we used a search of our topic carried out on textbooks for elementary and high schools. This search forms a part of introduction of our thesis. We carried out a considerable part of presented experiments personally during lessons with our students and distilled new experience into the final guidelines of presented experiments. Attachment plays a significant part of the thesis, above all video records of experiments and woorksheets for students. Experiments, with instructions included, update and supplement the subject Practical Course in School Experiments I, which forms part of the compulsory professional preparation of physics teachers at MFF UK. The experiments might therefore serve as an inspiration both for current and future physics teachers. They are synoptically presented in an online Collection of Physics Experiments (fyzikalnipokusy.cz/en).

Earth as a dynamic body
Dlask, Martin ; Čížková, Hana (advisor) ; Drozd, Zdeněk (referee)
This thesis is devoted to teachers and students of high schools. Its purpose is to deepen the knowledge that students may gain during geography lessons and to relate it to the information obtained during lessons of physics taught in high schools. The aim of this thesis is to introduce the most recent problematic of geophysics to students and to briefly explain the effects of physical laws, which they may encounter. This work is mainly focused on the description of the interior structure of the Earth, the Wave propagation thru the Earth, the heat movement of heat within the Earth and the rise of the magnetic field of the Earth. This thesis is divided into two parts, the first part is composed by study scripts in which are summed up and explained the geophysical findings about the Earth. For pedagogical purposes, physical findings that are needed to understand this thesis are also repeated and explained. The second part consists of a included presentation in PDF format that serves as medium for presentations about the Earth for teachers. Powered by TCPDF (www.tcpdf.org)

To Dvur Kralove by train - Transfer Terminal in Dvur Kralove nad Labem
Juránek, Marek ; Svojanovský, Viktor (referee) ; Žalmanová, Petra (advisor)
The terminal is becoming a heart of traffic in Dvur Kralove nad Labem. Linking of train and bus transport is inspired by a shape of a “courtyard” - open space, that is surrounded by buildings. This is a stage where acts of transportation, meetings, happiness and worries take place every day. Space has been designed so people don’t only use it for a purpose of transport, but also to enjoy moments of free time. The appearance gives a futuristic impression, however respects city’s history and tries to enrich its surroundings, so it doesn’t become just another place where people like to spend their time. Although trains and buses enter terminal from 21st century, design respects also its history as well as surroundings and use a form and function to promote them. “courtyard” terminal is a place for meetings and goodbyes, where a time flows and journey to adventure begins.

Wave editor
Šebesta, Michal ; Kofroň, Jan (advisor) ; Pop, Tomáš (referee)
The goal of the work is to develop an application for working with a sound. The aplication doesn't try to compete with a long time developed commercial application. It tries to point out what is the most important for sound editing. Therefore the application mainly contains the most important and the most comfortable elements. These elements are e.g. loading sound files, recording with microphone, editing functions, multitracking and various effects. Setting of shortcuts and design is comfortable for users, too.

"Everything's light and everything's upwards, the dance of elephants being uppermost". The metaphors of the movement in poetry of the poet Vladimir Holan.
Hudcová, Zuzana ; Heczková, Libuše (advisor) ; Wiendl, Jan (referee)
The purpose of the thesis is to deal with a writings of Vladimir Holan as a thematic unity, where the motifs are transformed. The metamorphosis depend on a time, when they have been written in. Our used method of his writings is in a chronological order. This thesis is focused on the motif of a movement and his metamorphosis in poetry of Vladimir Holan. The aim is to penetrate the problems of the movement as a physical activity and approached the movement as a confirmation of existence on a basis of Patočka's phenomenological phylosophy. Other chapters pay attention to analysis of motifs of movement, which are recognizable in Holan's poetry. Their feature change from lightness and freedom to heaviness and limitation. Afterwards the point of this work reaches the axis: a wind - a wave - a water flowed - a bird - a cloud - a stone - a snake - a wall. Due to the better understanding of Holan's work, we make a passing comment about the motifs which are connected with notised above. These connections will able to put our thoughts about Holan's conception in order.

High precision differential thermometer
Sieklik, Ivan ; Wilfert, Otakar (referee) ; Barcík, Peter (advisor)
This work describes the principles of measurements of refractive-index structural parameter. This parameter represent intensity of atmospheric turbulence which is measured by a differential temperature meter. Basic properties of atmospheric transmission environment are specified and their influence on optical wave is stated. Furthermore, this thesis also describes fundamental types of sensors dedicated to temperature measurements. The aim of this work was to create a differential temperature meter which is able to measure the refractive-index structural parameter.

Software for simulation of acoustic pressure distribution
Hampl, Filip ; Schimmel, Jiří (referee) ; Kurc, David (advisor)
This semestral thesis deals with the creation of software to simulate the distribution of sound pressure. Basic principles of sound propagation are explained which are necessary for an understanding of the issue. There is a description of the velocity potential and its application in creating simulations. Another issue is the introduction of wavefield synthesis, which is essentially a technology for simulation of primary sources with secondary sources. Advantages of wavefiled synthesis are discussed as well as disadvantageous aspects. The practical part of this work is creating a user interface in Matlab, which allows user to plot the distribution of sound pressure of one or interaction of more emitters. Another possible outcome is to display the directional characteristics of real resources. At the very end of the work the direction of further work is outlined.
