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.

Physical Layer Security of WPCNs With Imperfect CSI and Full-Duplex Receiver Aided Jamming

IEEE Access, 2019
In this paper, we investigate the secrecy performance of wireless powered communication networks (WPCNs) faced by multiple passive eavesdroppers, where the full-duplex (FD) receiver utilizes the harvested energy to send the artificial jamming for ...

Optimization Study of Valve Closing Schemes for Long‐Distance Gravity Flow Water Supply Systems Based on the NSGA‐II Algorithm

Engineering Reports, Volume 8, Issue 9, September 2026.
Taking the Ruyang Water Supply Project of Qianping Reservoir as the research object, a model was built with Bentley Hammer and valve closure schemes were optimized using the NSGA‑II algorithm. Results show that multistage closure is superior to single‑stage, and the optimized three‑stage scheme provides better water hammer protection, offering ...

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 ...

Integrated LEO Constellation and In‐Cabin Distribution System for Continuous Aircraft 5G Connectivity

International Journal of Satellite Communications and Networking, Volume 44, Issue 5, Page 594-606, September/October 2026.
ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency ( > 500 ms) and inadequate coverage at high latitudes,

Rethinking Political Islam in Iran: Contestation, Authority, and Reform

Middle East Policy, Volume 33, Issue 3, Autumn (Fall) 2026.
Abstract Political Islam in Iran is frequently portrayed in Western scholarship and policy discourse as a unified and rigid ideological system rooted in the 1979 Islamic Revolution. However, this article contends that it operates as a plural and internally contested field in which state‐directed, reformist‐clerical, and civic interpretations compete ...
