Abstract:

<p>In next-generation wireless networks, a Multi-Mode Device (MMD) can be connected with available Radio Access Technology (RAT) in a Heterogeneous Wireless Network (HWN). The appropriate RAT selection is essential to achieve expected Quality of Service (QoS) in HWN. There are many factors to select an appropriate RAT in HWN including Data rate, Power consumption, Security, Network delay, Service price, etc. Nowadays, the MMDs are capable to handle with multiple types of services like voice, file downloading, video streaming. Considering numerous factors and multiple types of services, i

Multiple Radio Access Technology (multi-RAT) communication with Low Power Wide Area Networks (LPWAN) significantly increases the flexibility of Internet of Things (IoT) applications. Location-based services that build upon such a multimodal communication architecture are able to switch to an optimal localization method depending on the constraints of the active wireless technology. Furthermore, the resulting location estimate can aid location-based handover mechanisms to reduce the energy consumption of a multi-RAT IoT device.

Abstract:

IntroductionAlt, or alternative, accounts are secondary profiles people use in addition to a main account on a social media platform. They are a kind of automediation, a way of representing the self, that deliberately displays a different identity facet, and addresses a different audience, to what someone considers to be their main account. The term “alt” seems to have originated from videogame culture and been incorporated into understandings of social media accounts. A wiki page about alternate accounts on virtual world Second Life calls an alt “an account used by a resident for something ot

Abstract:

Engagement in any capacity with mainstream media since mid-2001 has meant immersion in the cross-platform, multimedia phenomenon of Harry Potter: Muggle outcast; boy wizard; corporate franchise. Consumers even casually perusing contemporary popular culture could be forgiven for suspecting they have entered a MÃbius loop in which Harry Potter-related media products and merchandise are ubiquitous: books; magazine cover stories; newspaper articles; websites; television specials; hastily assembled author biographies; advertisements on broadcast and pay television; children's merchandising; and the

Abstract:

In a TED talk in June 2009, media scholar Clay Shirky cited the devastating earthquake that struck the Sichuan province of China in May 2008 as an example of how media flows are changing. He explained how the first reports of the quake came not from traditional news media, but from local residents who sent messages on QQ, China’s largest social network, and on Twitter, the world’s most popular micro-blogging service. "As the quake was happening, the news was reported," said Shirky. This was neither a unique nor isolated incident. It has become commonplace for the people caught up in the news t

Abstract:

IntroductionMusically-inclined people often speak about the soundtrack of their life, with certain songs indelibly linked to a specific moment. When hearing a particular song, it can “easily evoke a whole time and place, distant feelings and emotions, and memories of where we were, and with whom” (Lewis 135). Music has the ability to provide maps to real and imagined spaces, positioning people within a larger social environment where songs “are never just a song, but a connection, a ticket, a pass, an invitation, a node in a complex network” (Kun 3). When someone is lost in the music, they can

Abstract:

I remember the first time I saw a dead body. I spawned just before dawn; around me engines were clattering into life, the dim silhouettes of tanks beginning to move out in a steady grinding rumble. I could dimly make out a few other people, the anonymity of their shadowy outlines belied by the names hanging over their heads in a comforting blue. Suddenly, a stream of tracers arced across the sky; explosions sounded nearby, then closer still; a tank ahead of me stopped, turned sluggishly, and fired off a couple of rounds, rocking slightly against the recoil. The radio was filled with talk of Ge

Abstract:

Introduction Documentary film has grown significantly in the past decade, with high profile films such as Fahrenheit 9/11, Supersize Me, and An Inconvenient Truth garnering increased attention both at the box office and in the news media. In addition, the rising prominence of web-based media has provided new opportunities for documentary to create social impact. Films are now typically released with websites, Facebook pages, twitter feeds, and web videos to increase both reach and impact. This combination of technology and broader audience appeal has given rise to a current landscape in which
