Recognition of vehicles using signals sensed by smartphone
Nevěčná, Leona ; Vítek, Martin (referee) ; Smíšek, Radovan (advisor)
Thanks to the development in recent years, the placement of miniaturized sensors such as accelerometers, gyroscopes, magnetometers, global positioning system receivers (GPS), microphones or others to commercially sold smartphones is increasing. Use of these sensors (which are to be found in the smartphone) for human activity recognition with health care improvement in mind is a discussed theme. Advantages of the use of smartphone for human movement monitoring lies in the fact that it is a device that the person measured carries with them and there are no additional costs. The disadvantages are a limited storage and battery. Therefore, only accelerometer, gyroscope, magnetometer, and microphone were chosen because their combination achieves best results. GPS sensor was excluded for its lack of reliability in sampling and for being energy demanding. Features were computed from the measured data and used for learning of the classification model. The highest accuracy was achieved with the use of a machine learning method called Random Forest. The main goal of this work was to create an algorithm for transportation mode recognition using signals sensed by a smartphone. The created algorithm succeeds in classification of walk, car, bus, tram, train, and bike in 97.4 % with 20 % holdout validation. When tested on a new set of data from the tenth volunteer, the resulting accuracy counted as average form classification recall for each transportation mode reached 90.49 %.

The Concept and Development of Strict Liability in Czech Tort Law and its Inspirational Sources
Lovětínský, Vojtěch ; Elischer, David (advisor) ; Doležal, Tomáš (referee) ; Petrov, Jan (referee)
The Concept and Development of Strict Liability in Czech Tort Law and its Inspirational Sources Abstract The thesis deals with an analysis of strict liability in Czech tort law taking into account the inspirational sources of its regulation, including in particular German and Austrian law, the Principles of European Tort Law (PETL) and the Draft of Common Frame of Reference (DCFR). Further, a historical and possible future development of strict liability is analysed as well as the risks for which strict liability is imposed. The thesis is divided into two main parts. The subject-matter of the first General Part is especially the concept of the strict liability and the reasons for its application. Further, some related problems are analysed in this part which are relevant for the legal theory as well for the legal practice (e.g. defences, contributory negligence, possibility of the concurrence of claims). The subsequent Special Part contains an analysis of the types of strict liability and consists of four main chapters. The first chapter deals with a short overview of the historical development of the strict liability in Czech tort law. In the second chapter particular types of liability in the effective Czech Civil Code are presented and critically evaluated. In the third chapter the author deals with some...

Analysis of the logistic system in Drůbežářské závody v Klatovech
Pošarová, Marie ; Houška, Milan (advisor) ; Libuše, Libuše (referee)
The aim of this thesis is to optimize logistics costs in a food processing production enterprise. The thesis describes the whole logistics process in a particular company from the transport of live poultry intended for processing through the distribution of finished food products to customers. In the first phase the thesis is devoted to theoretical bases and concepts such as the creation and development of logistics, definition of logistics, logistics systems and distribution chains. In another part the theoretical knowledge
is applied to a particular company Drůbežářský závod Klatovy, a.s.and current logistical costs associated with distributing food products from external carriers
are examined. Subsequently the financial calculation is processed and using methods
of multi-criteria model it is decided in what model of vehicle to invest to ensure logistical tasks in a food processing enterprise. In the end the result is interpreted, from which
it emerges whether the logistic costs and investments in own vehicles are worth purchasing thus reducing logistics costs or not. Therefore the thesis can serve as a basis for the financial management of the company as to how it is possible to reduce costs
in the future and thereby improve earnings.

Selected problems of city public transport in Prague
Tolstokulakova, Anastasia ; Mervart, Michal (advisor) ; Hinčica, Vít (referee)
This bachelor's work describes integrated transport of Prague in terms of its functioning and development opportunities. At the beginning, it presents the most frequently used means of transport in the historical development. Then, the attention is paid to tariff zones and ticket system. In the practical part is devoted to opportunities of growth of the tram network, especially development of tram railway Počernická. Furthermore, investment and operating costs to the bus and tram lines are compared at the end of work.

Transport behaviour of inhabitants of the Czech Republic after 1989: geographical aspects
PRENER, Jan
The main topic of this thesis is a thorough analysis of transport behaviour of Czech population since 1989. The study mainly concentrates on the issue of geographical aspects and changes in spatial distribution utilization of individual means of transport after 1989, and especially in the analyzed decade 2001 - 2011. The primary task of analyzing transport behaviour of Czech population is statistical survey based on Sčítání lidu, domů a bytů 2001 and 2011. On the basis of this and map outputs are defined spatial disparities, their essential dependence and possible development in the next decade. The thesis represents a partial research of the transport system of the Czech Republic and its spatial organization. The topic is a very broad issue therefore it is not possible to identify all the major factors that have influenced the dynamic development of the transport branch in the Czech Republic. The theoretical part of this work brings a simple but complex view of the selected topic. The emphasis of the qualification thesis is focused especially on the quantitative survey, of which task is to indicate and describe the spatial changes of selected means of transport mentioned in the intercensal period. The thesis also involves a discussion about final issues of the analyzed topic in the individual sections. This discussion could be regarded as a kind of synthesis of existing scientific literature which focuses on transport behaviour and has developed it. Finally there are outlined some geographical aspects which influence the transport behaviour of the population at individual means of transport and the possible development of the examined issue in the following decade.

Everyday spatial mobility of population in the town Český Krumlov: patterns of individual mobility and their study by means of modern geo-information technologies
ROZKOŠNÝ, Filip
This Bachelor´s thesis is focused on analysis of everyday spatial mobility in the town Český Krumlov. The data needed for research were obtained by questionnaire and partly from GPS loggers. The purpose of research of this Bachelor´s thesis was to find out in what proportion are used the means of transport from the angle of the number of trips, distance covered and the time spent in them. Quite big difference of modal split was registered between average working days and Saturday. During Saturday car was used more times than walking whereas during the working days walking was preferred more than car. From the results it was obvious that the longest distance was travelled in car and the longest time was spent while walking. Another aim of this research was to find out the various purposes of trips according to their number, distance travelled and time spent on them. Differences between trips according to their purpose were registered between an average working day and Saturday. The average working days were characterised by periodically repetitive trips as trips to work and school whereas shopping trips, visit trips and free time trips were typical for Saturday. The longest distance from the total distance was travelled to work and school during the working days and to visit trips on Saturday. The longest time during the working days was spent on trips to work and school. During Saturday the longest time was spent on free time trips. All the results were compared to similar studies. This Bachelor´s thesis includes an accuracy comparison of data of everyday spatial mobility of members of one household. Those compared data were collected by GPS loggers and a questionnaire that was filled by the respondents.
