The aim of this thesis is to propose a new mobile service. At the beginning of this work are listed technologies, which are used in mobile communications. Furthermore, it defines the concept of mobile service, indicating a few examples. The practical part describes a custom design services and its variants. The new service is finally described as a possible new type of business.

This thesis is thematically focused on the use of modern technology in economic education at secondary schools. The theoretical part discusses the issue of modernization of education, including the presentation of the Ministry of Education document Strategy digital education by 2020. Furthermore in the context of theoretical analyzed in detail the different types of modern technology and the last chapter of this part of this thesis deals with current projects, which are designed to support the modernization of education. In the empirical part of this thesis, analyzes a survey carried out among teachers of business subject at secondary schools and pupils at a secondary school as well. The aim of this section is to use the survey to determine attitudes of teachers and students to modern technologies. And then also examine the possibilities of new modern technologies in teaching business subjects.

The present thesis deals with the use of mobile technologies in the follow-up to ERP systems. Goal is to analyze the integration of mobile technologies into the corporate environment. The thesis at first analyses the existing state, reasons for and benefits of use of mobile technologies in the corporate sphere with the use of the research methodology of semi-structured interviews. This part is concluded with the author's evaluation of investigated cases and with identification of other related types of solution in practice. The final part of the thesis is dealt with the case study in a Czech company. This part of the thesis starts with an analysis of the current state of information and communication technologies in the company on the basis of consultations and visits to employee workplaces; subsequently it specifies opportunities for improvement of support of selected corporate processes for which possible solutions are proposed in the final part of the thesis. The thesis brings some still unpublished information with regard to the use of mobile technologies in the business environment.

This diploma thesis is focused on the design and development of applications for mobile devices with Android operating system. The main purpose of this application is to fulfil the requirements of law on the Electronic Records of Sales. The thesis describes the theoretical knowledge which is important in the development of the application and describes the design and the whole implementation of the application. The application is implemented in the Java programming language. The thesis also deals with the description of the problem of electronic records of sales and the analysis of the EET product range.

The main target of this work is to design and to implement unfailable safety appliance for motocycles with use any GSM technology. In my masters’s thesis I applied to individaul fields which I had to knows for realization of this work. The introductory chapter tells the reader about evaluation of former semestral projects and about brief description of the realized mechanism. It is followed by descripctoin of principles of communication between PC and mobile phone. The main part of my work is dedicated to application itself. The applicaton is called motoalarm. The last chapter creates description service of localisation mobil phones which is called Kde je... The conclusion includes evaluation of this master´s project and general description of the realized mechanism.

This thesis deals with theoretical design and practical realization of map editing application. The first chapter is focused on theoretical explanation of the most important terms in GPS describing basic principles and position monitoring possibilities. Further is described block scheme of GPS receiver. Next chapter describes NMEA 0183 protocol which is used for data transfer between GPS module and application. At the end of theoretical part is some information about geodetic system WGS-84 and files for trace recording. Application is creating in .NET Compact Framework in C# language. Application is able to load map in image format. Trace from specific file format can be displayed into map. Application can show currently recording trace too. Trace can be divided on segments according to type roads. Weak signal in record trace can be modified by correction methods. At the end of this thesis are instructions to using created application.

The diploma thesis solves the problem of design and implementation of library for digital signal processing on Android platform. It describes problems with development software on this platform. There is also a debate about portion of Android on market. It describes technologies and ways, that were used for developing an application. It also explains the efficient programming techniques, in some cases, offering alternative solutions and ways. Effectiveness examines from the perspective of processing power and memory consumption. Continues through analysis Android platform architecture, and some features of its system to the description of some of its parts. Gets up to the description of work with the audio data formats, or to work with files and various collections of data. Then description continues with functions and the application itself. The actual library is controlled through the user interface and some other functions. User select parameters of each signal to be processed. The signal can be generated or the recorded sound signal. After selecting the parameters of each filter, the user can play the output signal and observe the change. In other part different instruments are compared and discussed some improvements, which accelerate and improve the entire application. The conclusion summarizes the results and benefits of the entire diploma thesis.

This thesis is dedicated to communication with lost mobile device throw the Internet with its owner because of the possibility of finding, return or lock the device. It focused on analysis existing solution and draft own mobile application for Android platform with supportive web application, This thesis also summary basic principles of creating application for Android OS and communication with cloud base service Google Cloud Messaging.

This thesis deals with voice encryption in wireless communication. First, the necessary theoretical base about mobile telephone network is presented and followed by a description and comparison of existing voice encryption methods in wireless communication. After that, modern cryptographic algorithms are briefly described and a method based on voice over Internet protocol is proposed. This method is implemented as an Android application.

This master's thesis deals with application design and implementation of secured communication between smartphones. Analyses issues of cross-platform portability between operating systems, its differences and common features. It shows an overview of Android OS architecture and its individual layers. Thesis describes basic principles of secured communication in the modern cryptography and implementation of application for mobile platforms. Also shows an overview of modern mobile technologies such as NFC (Near Field Communication) and Bluetooth. This thesis reveals basic architecture and the way how it fits into concept of secured communication. It also describes the architecture of application and concept of secured communication, which is then implemented. In conclusion is summarization of achieved results and possible extensions of implemented application.
