Channel transition invariant fast broadcasting scheme [PDF]

2014 9th International Forum on Strategic Technology (IFOST), 2014
Fast broadcasting (FB) is a popular near video-on-demand system where a video is divided into equal size segments those are repeatedly transmitted over a number of channels following a pattern. For user satisfaction, it is required to reduce the initial user waiting time and client side buffer requirement at streaming.

Empowering citizens to spontaneously report suspected adverse drug reaction: Systematic literature review of interventions and their impact

British Journal of Clinical Pharmacology, EarlyView.
This systematic literature review aimed to identify and characterize existing interventions designed to empower citizens to spontaneously report adverse drug reactions (ADRs) and to determine which interventions have been shown to be the most effective internationally. The research question was structured using the PICO framework.

Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

On source and channel codes for multiple inputs and outputs: does multiple description beat space time? [PDF]

, 2005
We compare two strategies for lossy source description across a pair of unreliable channels. In the first strategy, we use a broadcast channel code to achieve a different rate for each possible channel realization, and then use a multiresolution source ...

Bridging home, school and community to address educational inequality: Supporting educational trajectories through community bridge work

British Educational Research Journal, EarlyView.
Abstract This paper explores the role of community stakeholders in supporting the educational trajectories of students experiencing socio‐economic disadvantage in the Irish context. Building on international and national policy debates, the study examines how community‐based organisations, statutory services and outreach initiatives work alongside ...

Improving TCP Performance over Wireless Ad Hoc Networks with Busy Tone Assisted Scheme

EURASIP Journal on Wireless Communications and Networking, 2006
It is well known that transmission control protocol (TCP) performance degrades severely in IEEE 802.11-based wireless ad hoc networks. We first identify two critical issues leading to the TCP performance degradation: (1) unreliable broadcast, since ...

Individual Secrecy for the Broadcast Channel [PDF]

IEEE Transactions on Information Theory, 2017
This paper studies the problem of secure communication over broadcast channels under the individual secrecy constraints. That is, the transmitter wants to send two independent messages to two legitimate receivers in the presence of an eavesdropper, while keeping the eavesdropper ignorant of each message (i.e., the information leakage from each message ...

‘Sometimes, I would look at my books and cry because I felt like I was left behind’: Understanding the learning of Indigenous girls during the COVID‐19 pandemic in the districts of Chongwe and Solwezi in Zambia

British Educational Research Journal, EarlyView.
Abstract Grounded in principles of epistemic justice, this article examines the educational impacts of Zambia's COVID‐19 school closures on Indigenous girls in two districts and highlights community‐led pathways for resilience. National responses prioritised broadcast and digital delivery but presupposed access to electricity, digital devices and ...

Compress-and-Forward for Relay Broadcast Channels without Common Messages

Cybernetics and Information Technologies, 2015
This paper is connected with compress-and-forward strategy for two-user relay broadcast channels without common messages, where the relay node has private messages from the source, in addition to aiding traditional communication from the source to the ...
