As one of the developing technologies and increased use in the field of ed-ucation, Augmented Reality (AR) technology adds a digital (audio, video, graphic and GPS location) layer to authentic world images. The aim of this study is to determine students’ attitudes regarding AR contents developed for science education. The study group consists of 77 7th grade students studying in a private college during 2018-2019 academic year spring se-mester. The study adopted quantitative data collection method and imple-mented Attitude Scale for Augmented Reality Applications. The collected data were analyzed through paired samples statistics, mean and standard deviation. The data analysis showed that students were satisfied with AR applications, found it interesting and easy to use and would like to use it in the future.

Integrated Antenna

Digital Audio Broadcasting (DAB) system is one of the high - definition radio with the ability to provide high audio quality and data - based services for stationary and mobile receivers. Digital Video Broadcasting (DVB) is the popular broadcasting standards that enable handheld receivers to receive high definition digital television transmissions. Orthogonal Frequency Division Multiplexing (OFDM) system is a digital multi – carrier modulation technique intend offers high spectral efficiency. The main aim set is to arrive as an efficient unified system for multipurpose wireless system that would cater to all existing standards. This paper presents the unified approach for designing an integrated antenna for DAB and DVB using OFDM system. In this paper DAB and DVB using OFDM system is designed individually and their performance is measured by Bit Error Rate (BER). Integrated antenna for DAB and DVB using OFDM system is designed and simulated radiation patterns are presented. The proposed unified approach produces the better BER performance and better gain as compared to individual standard design

Mobile Television

Mobile television is potentially the most anticipated mass-market mobile application across Europe. This chapter examines the business model design of mobile TV by the various stakeholders currently piloting mobile broadcasting in the European national markets. It adapts a generic business model framework to systematically compare five recent pilots of the two mobile broadcasting technologies that are currently trialled most intensively in Europe, that is, digital video broadcasting-handheld (DVB-H) and digital audio broadcasting-Internet protocol (DAB-IP). The article illustrates the cross-impact of cooperation agreements between the various stakeholders with technological, service- related, and financial design choices. It also provides insights as to the likely business models in the upcoming commercialisation phase of mobile broadcasting in Europe.
