although, once, in the far past, sending gifts and missionaries was called a type of public diplomacy, today it is manifested as academic disciplines, policy making institutions, and multi-purpose organizations. the most important institutions of these kinds, now, exist in the us, whose purpose is to promote the politics of this country as public diplomacy and to follow local and international ...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...

MarconiNet is an architecture for IP-based radio and TV networks, built on standard Internet protocols including RTP, RTSP, SAP, and SDP. It allows to build virtual radio networks, similar to traditional AM/FM radio and TV networks. It addresses some of the practical problems of building Internet radio networks, including the insertion of local content and advertising.

Traditional live TV broadcasting systems are proven to be spectrum inefficient. Therefore, researchers propose to provide TV services on 4G LTE networks. However, static broadcast, a typical broadcasting method over cellular network, is inefficient in terms of radio resource usage. To solve this problem, the Audience Driven live TV Scheduling (ADTVS) framework is proposed, to maximize radio res...

Morpho-syntactic patterns device encompasses a subcategory of the cohesive devices that assists hearers to have an adequate mental representation for understanding speech. This article investigates the morpho-syntactic patterns employed in some Persian live sport radio and TV programs adapting Dooley and Levinsohn’s theoretical and analytical framework. The research data includes around 30,000 ...

Cognitive radio has been an active research area in wireless communications over the past 10 years. TV Digital Switch Over resulted in new regulatory regimes, which offer the first large-scale opportunity for cognitive radio and networks. This article considers the most recent regulatory rules for TV White Space opportunistic usage, and proposes technologies to operate in these bands. It addres...
