Power allocation for estimation outage minimization with secrecy outage constraints [PDF]
2016 Australian Communications Theory Workshop (AusCTW), 2016 In this paper, we investigate the distortion outage minimization problem for a wireless sensor network (WSN) in the presence of an eavesdropper. The observation signals transmitted from the sensors to the fusion center (FC) are over-heard by the eavesdropper.

The Effect of Power Outages and Cheap Talk on Willingness to Pay to Reduce Outages [PDF]
SSRN Electronic Journal, 2009 Using an open-ended contingent valuation survey, we analyze how (i) experience of a power outage due to one of the worst storms ever to hit Sweden and (ii) a cheap talk script affect respondents' WTP to avoid power outages. Experience significantly increases and a cheap talk script significantly decreases the proportion of respondents with zero WTP ...

#Outage: Detecting Power and Communication Outages from Social Networks [PDF]
Proceedings of The Web Conference 2020, 2020 Natural disasters are increasing worldwide at an alarming rate. To aid relief operations during and post disaster, humanitarian organizations rely on various types of situational information such as missing, trapped or injured people and damaged infrastructure in an area.

Outage-constrained robust power allocation for downlink MC-NOMA with imperfect SIC [PDF]
, 2018 In this paper, we study power allocation for downlink multi-carrier non-orthogonal multiple access (MC-NOMA) systems and examine the effects of residual cancellation errors resulting from imperfect successive interference cancellation (SIC) on the system

Outage analysis of superposition modulation aided network coded cooperation in the presence of network coding noise [PDF]
, 2015 We consider a network, where multiple sourcedestination pairs communicate with the aid of a half-duplex relay node (RN), which adopts decode-forward (DF) relaying and superposition-modulation (SPM) for combining the signals transmitted by the source ...

Revisiting and Modeling Power-Law Distributions in Empirical Outage Data of Power Systems
PRX Energy, 2023 The size distributions of planned and forced outages and their restoration times in power systems have been studied for almost two decades and have drawn great interest as they display heavy tails.

Bayesian Estimates of Transmission Line Outage Rates That Consider Line Dependencies [PDF]
, 2020 Transmission line outage rates are fundamental to power system reliability analysis. Line outages are infrequent, occurring only about once a year, so outage data are limited.
