Secrecy Outage Probability Analysis for Downlink RIS-NOMA Networks With On-Off Control

IEEE Transactions on Vehicular Technology, 2023
Reconfigurable intelligent surface (RIS) has been regarded as a promising technology since it has ability to create the favorable channel conditions. This paper investigates the secure communications of RIS assisted non-orthogonal multiple access (NOMA) networks, where both external and internal eavesdropping scenarios are taken into consideration ...

Alternative Contract Design: Analysing the Bankability of Fungible Derivative Contracts in Energy‐Only Markets

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT With the retirement of 21GW of legacy coal fleet looming, the task to replace Australia's thermal capacity with alternative firmed renewable ‘bulk energy’ solutions is non‐trivial. Indeed, calibrating necessary capital investment in new plant stock with efficient economic outcomes, vis‐à‐vis cost and reliability, represents a fundamental ...

Make or Buy Decisions and Data Sharing

The Journal of Industrial Economics, EarlyView.
ABSTRACT Firms can share data to discover potential synergies between their data sets and algorithms, eventually leading to more efficient mergers and acquisitions (M&A) decisions. However, data sharing also modifies the competitive balance when firms do not merge, and a company may be reluctant to share data with potential rivals.

Design and Implementation of a Digitalised Marine Aids to Navigation Monitoring System for High‐Density Maritime Traffic Waters: A Case Study of the Strait of Malacca

Applied Research, Volume 5, Issue 5, October 2026.
A digitalised Aids‐to‐Navigation monitoring system (ARMS) was deployed across 478 installations in the Strait of Malacca and Malaysian waters, integrating multi‐sensor edge validation, hybrid AIS/VHF/cellular communication, and a centralised platform. It achieved 98.3% availability and cut fault‐detection time from weeks to just 8.4 min.

Laser Surface Treatment of Nickel‐Alumina Coating for Enhancement of Erosion and Corrosion Resistance of High Speed Steel Vanes

Applied Research, Volume 5, Issue 5, October 2026.
Laser surface treatment was carried out to enhance the performance of Ni‐Al2O3 coatings on HSS substrates. The results revealed improved microstructural features, corrosion resistance and significant reduction in slurry erosion wear with 18 W laser treatment. ABSTRACT The sliding wear between hydraulic vane tip and the inner surface of the cam ring can

Secrecy outage probability of cognitive small-cell network with unreliable backhaul connections

, 2019
In this paper, we investigate the secrecy performance of underlay cognitive small-cell radio network with unreliable backhaul connections. The secondary cognitive small-cell transmitters are connected to macro base station by wireless backhaul links. The

Secrecy outage probability analysis of multi-user multi-eavesdropper wireless systems [PDF]

2014 IEEE/CIC International Conference on Communications in China (ICCC), 2014
In this paper, we explore the physical-layer security of a multi-user wireless system that consists of multiple users intending to transmit to a base station (BS), while multiple eavesdroppers attempt to tap the user transmissions. We examine the employment of multi-user scheduling for improving the transmission security against eavesdropping and ...
