The main objective of this diploma thesis is to design and develop a cloud hosted service that allows developers of games for Windows Phone 7 platform to extend their products with social and competitive aspect using Platform as a Service solution Windows Azure for hosting the backend of this system. The first part of the thesis analyses systems that are available on the market and that are providing similar services for the target platform. Based on this analysis, functional and general requirements for the future application are specified in the second part. Based on these requirements, use case analysis is made. The third part of the thesis is dedicated to description of the most important features, APIs and specifics of the Windows Phone 7 software platform. The fourth part is dedicated to Windows Azure as a Cloud platform both in terms of most important services, their characteristics and APIs used to utilise them and in terms of their business and pricing conditions. The fifth part addresses the architecture and the most important implementation details of the application. The final part contains the user guide for both the Windows Phone 7 application and for developers interested in using the library containing the API during the development of their game. The output of this thesis is the designed and implemented application with client-server architecture ready to have its backend deployed in Windows Azure environment and to have its frontend deployed on Windows Phone 7 devices. The client part of the system is comprised of a library intended for developers of games, which encapsulates the API needed to access the backend on the Internet, and a graphic frontend intended for end users. The server part, which contains most of the application logic, has REST interface. The applications architecture allows future development in terms of new functionality and expansion on more client platforms.

The theme of the thesis is an analysis of current mobile operator selected services. This work focuses on the present and the future development of mobile internet connection. The aim is to analyze existing services at Telefónica Czech Republic and The work is divided into several parts. The first part focuses on the selection of a particular operator. I described at al. Czech Republic and Telefónica, which is the first integrated operator in the Czech Republic. The company currently operates more than seven million mobile numbers and fixed lines, making it one of the leading providers of fully converged services in Europe. I focused on the organizational structure of the company and its description. The second part is historical, describes the history of mobile networks in the CR, the history of mobile communications in the data and the development of mobile connections in the country. The third part is theoretical, describes al. Czech Republic Telefonica SpA in terms of services it offers in this section is also described ISO certification, EMS policy and business principles. Are described voice and mobile services, mobile data services and connectivity technologies and different types of technologies (GSM, GPRS, EDGE, UMTS, HSDPA, HSPA + and LTE). Another section includes the development of mobile connections in the CR, the current situation where Telefónica provides 3G connection for almost 71% of the population and the current state of commercial LTE network. I tried to describe the current mobile platforms, and even telecommunications market in the Czech Republic. The penultimate section specifies the geographic traffic distribution network operator and the last part, I dealt with the analysis and comparison services. The total contribution of the thesis see the approach and evaluation of existing services together. Telefónica Czech Republic, as, which is one of the largest telecommunications companies in the world.

The main objective of diploma thesis is to describe and analyze the issue of mobile devices and mobile applications, focusing on their usage in the information system of enterprise in terms of deployment rules for security, mobile device management and enterprise operation in implementing mobile policy in to business. The diploma deals with aspects related to the deployment of mobile enterprise policy in terms of choosing the right operator, a suitable mobile platform, mobile device management and applications to ensure optimal information security in company. The aim is compare Czech operators and most frequent mobile operating platforms in terms of business needs and determine the most appropriate mobile operator and mobile operating system suitable for the implementation of mobile policy in to business. Another goal is analyze and describe the method of mobile device management and applications, and to ensure their safety and universally describe the main advantages and disadvantages of deploying mobile policy in to business. The practical part is focused on the public inquiry to identify and analyze the current situation of enterprises in implementing mobile policies in the Czech Republic. Survey results are analyzed, described and summarized in the recommendations and alternative solutions for Czech companies for next years.

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 %.

This master's thesis focuses on smartphone game for iOS, which uses recognition of face features and other information, which can be obtained from a smartphone's camera and sensors. This work describes a few approaches for real-time face detection and then introduces and compares possibilities for such task on iOS. Moreover, the thesis contains a draft of the final game and its levels. The game showcases various technologies in its levels such as object detection, processing an image color and others. Finally, the thesis introduces the final form of the game that is released and available on the App Store.

This master’s thesis dissertate the possibilities of the linkage between Asterisk softswitch and the 4th generation private branch exchange. This should create a new generation’s network, so-called NGN, by the convergence of existing telecommunication networks with an IP computer network. This master’s thesis is divided into several chapters. In introduction is described the evolution of the private branch exchanges as well as the principles of the voice digitizing, codecs and signaling commonly used in both TDM and VoIP networks. The main aim of this project is the configuration of Asterisk software exchange for connection with PBX Alcatel 4400 as well as public phone network PSTN. Another goal of this master’s thesis was the configuration of Alcatel PBX and diagnostics of CCS and CAS signaling on E1 interface. In conclusion there are summarized advantages of NGN networks and their utilization in the future.
