In this paper, we develop a new dynamic utility for wireless access virtualization (WAV) optimization embodying highly-dimensional time-varying multi-criteria metrics (i.e., CaPeX and OPEX costs, QoS or QoE, multitier and/or multi-RAT HetNets, etc.) that gauge the best deployment and viability scenarios of cloud (C)- and fog (F)-RANs within legacy networks. Exploiting the powerful tool of graph theory, we devise a progressive greyfield WAV strategy that optimizes our dynamic utility through an efficient combination of C- and F-RANs. This strategy is able to readjust very quickly to any changes in existing or new constraints as they evolve or occur in time, respectively. The resulting optimized hybrid RAN deployment outperforms both the greenfield and the pre-planed greyfield ”turnkey” WAV strategies.

This article charts how movies were integrated into the existing popular print culture of weekend newspapers in North America between 1911 and 1915. Neither the movie theatre nor the newspaper should be given priority as the primary site of cinema culture. The practice of reading a newspaper’s film page would be incomplete without a trip to join the mass audience at a movie theatre; conversely, a moviegoer’s pleasure could be whetted by the print supplement. Early, isolated experiments in metropolitan newspapers led to syndicates offering film pages for reproduction in small town papers. With the proliferation of moving picture publicity in newspapers throughout 1913, film studios began to collaborate with newspaper syndicates on a continental scale. Movie stories appeared in daily and weekly forms in various newspapers chains, well beyond the familiar ‘serial queen’ fiction tie-in. A subscription to the newspaper could become a commitment to engage with the mass market for movies. Insofar as a public is ...

As traditional spectrum sensing approaches unable to deal with the contradiction between detection accuracy and complexity in cognitive radio network, a novel q-weighed sequential cooperative energy detection method for spectrum sensing in time varying channel is proposed in this paper to achieve better performance with lower complexity. By adding the q- weighted log likelihood ratio (LLR) of the past local observations from previous sensing slots to the current LLR sequentially, cognitive radio nodes can aggregate the current and previous received energy values to yield the improvement of sensing performance. Moreover, we pose a q-weighted K-out of-N voting rule at the fusion center to minimize the total error probability. For different probability of primary signal for turning its state from active to idle, we employ corresponding different weighted value q to make the sensing scheme more flexible and efficient.

Future 5G systems will include a point-to-multipoint (P2MP) transmission mode to achieve high capacity and high spectrum efficiency for multiple use cases, such as IoT, lifeline communications, and broadcast-type services. Layered-division-multiplexing (LDM) is a novel non-orthogonal multiplexing technology recently adopted by the next generation digital TV broadcast system, ATSC 3.0, which is capable of providing significant capacity improvement when delivering multiple broadcast services simultaneously. This article explores the application of LDM as an enabling technology for 5G to achieve high-efficiency P2MP transmission and to deliver more diversified broadcast-type services using the mobile broadband infrastructure. The potential advantages that can be offered by LDM are demonstrated by capacity analysis and computer simulations. Coverage studies show that a 5G P2MP subsystem with LDM can deliver high-quality broadcast services using the broadband infrastructure. Finally, some general guidelines on the receiver implementation are presented to minimize the hardware complexity of consumer devices.

This paper explores the contributions of autonomist Marxist theory to my understanding of reality television, self-branding and social media. Autonomist Marxist ideas help to bridge the classic media studies divide between critical political economy and cultural studies, illuminating the very material connections between television’s mode of production, its texts, and its broader cultural context and impact. Concepts such as the social factory, immaterial labour, the socialized worker, and virtuosity, contributed by thinkers such as Mauricio Lazzarato, Paolo Virno, Antonio Negri and Michael Hardt, have enabled me to argue that reality television is a privileged site of production in the post-Fordist era; it not only produces texts or ideologies about work and life, but also models the monetization of “being” and produces “branded selves”. While autonomist ideas are extremely useful, the field of thinking is complex and not without its internal debates. This paper also explores contributions by George Caffentzis, Massimo de Angelis and David Harvie, specifically the concept of the war over measure, arguing that this concept helps to frame some of the ways in which the public expression of opinion and feeling online and in social media are being captured, measured and put to work for capital.

In this article, we study the uplink coverage and the uplink network throughput of an ultradense network (UDN) where human-type communication (HTC) users and machine-type communication (MTC) devices coexist. We employ non-orthogonal multiple access (NOMA) radio access to address the massive connectivity requirements of MTC while satisfying the high data rate requirements of HTC. To this end, stochastic geometry is utilized to model the network exploiting the inherent randomness of the proposed scenario. The enormous number of small cells in UDN along with NOMA can provide a common ground to satisfy the diverse requirements of both MTC and HTC. The distinguishing features of both UDNs and MTC are considered in modeling the network where stretched exponential path-loss (SEPL) is used to capture short-link distances. Moreover, the truncated channel inversion power control is employed in both HTC users (HTCUs) and MTC devices (MTCDs) to mitigate the uplink intercell interference. The results show the significant impact of various system parameters on the network performance. Closed-form and easy-computable expressions are derived for the considered performance metrics, and are assessed by Monte Carlo simulations.

Travaillant depuis plusieurs années sur les écritures de voyage, je propose dans cet article une analyse transversale des carnets tenus par des backpackers. Objet polymorphe, à la fois écritures ordinaires du voyage et écritures laissant entrevoir une intimité du voyageur, le carnet de voyage nécessite la mise en place d’une méthodologie spécifique –– observation participante — pour son obtention ou tout simplement pour sa consultation. Au-delà des caractéristiques significatives de la population témoin et du corpus constitué, j’aborderai succinctement la question de la matérialité de l’objet pour laisser une place significative au contenu du carnet. Ainsi, je soulignerai les thématiques que l’on trouve dans l’ensemble de la production et porterai une attention toute particulière à la question du « je » dans ce corpus. Ainsi, feront jour des interrogations, des affirmations du voyageur que seul le carnet de voyage peut révéler. À travers cette production témoignant d’une expérience quotidienne d’itinérance d’une population difficilement saisissable pour l’anthropologue, ce n’est plus une seule présentation d’un pays qui sera dévoilée, mais un ensemble d’éléments construisant une identité narrative. Le carnet apparaîtra alors comme une trace de voyageur, une trace biographique faisant récit et donnant la pleine mesure de la dimension anthropologique du voyage.
