Classification of free living data
Rychtárik, Martin ; Vítek, Martin (referee) ; Smíšek, Radovan (advisor)
The topic of this bachelor thesis is classification of free living data, captured by the accelerometer sensor of a smart phone. The first part of the thesis deals with the possibilities of recording daily activity using accelerometer and subsequent classification by neural network. In the next section, the data of eight different daily activities were recorded on ten people. An algorithm containing a neural network was created for the data in the MATLAB programming environment to automatically identify the activities. In the last part of the work the algorithm classification was compared with manually recorded reference and the results were statistically evaluated.

Measuring of pulse rate using smartphone
Víteček, Jiří ; Smital, Lukáš (referee) ; Němcová, Andrea (advisor)
This bachelor thesis deals with the possibility to measure heart rate using a smartphone. Today, many people own a smartphone. Newer devices can record various data thanks to its sensors and additional equipment. The current trend is to use the data so that the mobile phone can replace other devices, e.g. navigation, camera, camcorder or multimedia player. Recently, mobile phones have also been used in the field of medicine and, thanks to their mass extension, there is the potential to use them to detect health problems early on. With a functional mobile application, testing becomes cheap, fast, always available and easy to the general public. The beginning of the thesis describes the basic facts about physiology and anatomy of the heart, and circulatory system. Methods of heart rate monitoring using standard devices and smartphones, and measurement history are discussed as well. Two proposed methods using the smartphone's microphone and accelerometer are described below. For each method, testing and statistical evaluation are described. The thesis confirmed the possibility of using these methods for relatively accurate pulse rate measurement, even under different measuring conditions. Created applications with graphical user interfaces are described in the thesis including examples. The last part contains a comparison of methods, recommendations for measurement and final evaluation.

Quantitive optical analysis using cell phone
Petlák, Daniel ; Svoboda, Ondřej (referee) ; Čmiel, Vratislav (advisor)
This bachelor‘s thesis discusses methods for the quantitative colorimetric analysis using a cell phone and a design of my own analyzer. Theoretical part deals with basic characteristics of light and division of optical spectral analysis, which is described by several optical methods. The bachelor’s thesis also contains the division of colorimetric analyzers according to their types. The most important part is focused on a colorimetric analysis using the cell phone and familiar with the possibilities of analysis of liquids and solid samples. The practical part deals with the design of a separate analyzer using the cell phone, developed application including the possibility of calibration values of prepared samples and subsequent evaluation of ion concentration in unknown sample. For the accuracy of the results is made dark light-tight cover printed by 3D printer.

Modern Addictions
NÝDLOVÁ, Leona
This thesis addresses the issue of mobile phone use and abuse in the context of healthy living. The theoretical part works with the concept of smartphone addiction, nomophobia. It describes the risks of mobile phone overuse and the effects on health and healthy functioning that overuse can cause. It characterises the most common non- substance addictions that the mobile phone as a tool helps to develop. Addresses the ethics of the online space. Discusses prevention options from the non-profit sector and from governmental institutions. The practical part is devoted to the problem of mobile phone abuse in the adult population in České Budějovice. It divides respondents according to their socio-demographic characteristics and looks for factors that may be related to addiction in this region.

Printed Book Versus E-book Readers. The Future of Literary Culture in the 21st Century
Šulcová, Lucie ; Řehořová, Irena (advisor) ; Fišerová, Michaela (referee)
This master thesis is dedicated to comparison of classical book and electronic book reader and it examines the advantages and disadvantages of both formats for recipients. In this work the importance of the printing press for society will be described and also the reactions which were induced by its invention. Following chapters will be dedicated to the book itself. Most importatntly what "makes the book being the book" and what are its strength and weeknesses and why it is still popular. As a contrast to this phenomenon the massive increase in popularity of electronic book - especially e-readers in pocket readers, on the internet and in the smartphones which become potential competition for books. The goal of this work is to compare the printed version which is represented by paper book and electronic version which is represented by e- books. Comparison will be based on the description of the specifics of both information tools from technological aspect as well as from the different text perception and the enjoyment from the reading itself. At the end there is an attempt to predicate the possible development in the future - is book culture facing a crisis or will it hold its position in following years?

The influence of brand on consumer buying behavior
Aliapulios, Telis ; Vokáčová, Lucie (advisor) ; Ludmila, Ludmila (referee)
The diploma thesis concerns with influence of Apple brand on consumer buying behavior. The aim of thesis is to qualify the influence of brand on consumer buying behavior on smartphone market. From this conditions will arise the recommendations to Apple company, how is possible to bolster its position on mobile phone market. The theoretical part of thesis place emphasis on description of marketing mix, brand theory and consumer buying behavior. Practical part is based on studied secondary data. There is detailed description of Apple company its brand building strategy, situation on smartphone market with marketing instruments, that are used on this specific market. Quantitative questionnaire survey performed in electronical form creates a core of the practical part of the thesis and is preceded by qualitative pre-survey on seven iPhone users. Precisely 154 respondents participated on questionnaire survey that observed thoughts and judgements of questioned people about Apple brand. There are included opinions of owners, that own various smartphone brands and also respondents from the group of Apple iPhone users. The responses of both groups are in the chapter of appraisal results and conditions compared along with studied secondary data. These outcomes of questionnaire survey and secondary data are used as a framework to completion several recommendations for Apple brand and the whole company on this market. Almost three quarters of owners, that use all chosen smartphone brands, perceive the prices of Apple smartphones as overly high. Just as the first group evaluates the situation a bit more than half of the iPhone users, although inside this group is a lower sensitivity on Apple products price perception. One of the important recommendation for Apple company is to be more efficient in communication about the adjustment of its smartphone prices and pricing policy towards to consumers across the countries. It is necessary to obtain more consumers from a group of new Apple brand users and students. These expects the offer of cheaper smartphone in high quality medium category. In case of their satisfaction is there scope for Apple to offer them its premium smartphones in the top category.
