In a society predicated on information, the media has a pervasive presence. From government policy to leisure television, the information age touches us all. The papers collected in this book constitute some of today's leading analyses of the information industry. Together, these essays represent a needed foundation for understanding the present state and future development of the mass media. Current trends in communications as well as media impact on public opinion are studied and reported on. Topics include a brief introduction on software radio to ultra wideband radio communications; wideband slotted microstrip antennas for modern applications; Device-to-Device (D2D) communication in 5G networks; the use of mobile devices to support young people with disabilities; and singular optimal control of switched systems. The final chapter is a proposal to support the teaching of history with audiovisual content, including video game advertising.
