Reliable online social network data collection [PDF]

, 2012
Large quantities of information are shared through online social networks, making them attractive sources of data for social network research. When studying the usage of online social networks, these data may not describe properly users’ behaviours.

Bootstrapping opportunistic networks using social roles [PDF]

, 2011
Opportunistic routing protocols can enable message delivery in disconnected networks of mobile devices. To conserve energy in mobile environments, such routing protocols must minimise unnecessary message-forwarding.

Loss of information in feedforward social networks [PDF]

Journal of Complex Networks, 2017
We consider model social networks in which information propagates directionally across layers of rational agents. Each agent makes a locally optimal estimate of the state of the world, and communicates this estimate to agents downstream. When agents receive information from the same source their estimates are correlated.

Learning the Nature of Information in Social Networks

Proceedings of the International AAAI Conference on Web and Social Media, 2021
We postulate that the nature of information items plays a vital role in the observed spread of these items in a social network. We capture this intuition by proposing a model that assigns to every information item two parameters: endogeneity and exogeneity.

Low-Complexity Architecture of Orthogonal N-Continuous Precoding for Sidelobe Suppression of OFDM Signals and Its Analysis

IEEE Access
High sidelobes of orthogonal frequency-division multiplexing (OFDM) signals must be resolved for future wireless communications. In this study, we propose and analyze an efficient orthogonally linear precoding to suppress the sidelobes in OFDM systems ...
