Tracing Three Decades of Low Earth Orbit Satellite Communication Development: A Bibliometric and Main Path Analysis of Network Architectures, Protocol Evolution, and Emerging Intelligent Services

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Low Earth Orbit (LEO) satellite communication systems have evolved into a critical component of global broadband networks, enabling wide‐area connectivity, IoT services, and intelligent multilayer satellite–terrestrial integration. Despite rapid advancements in constellation deployment, routing mechanisms, resource management, and LEO–5G/6G ...

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

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
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 ...

Advancing Sustainable Consumption in the Green Skincare Sector: Examining Celebrity Endorsements Through the Theory of Planned Behavior and Source Credibility Theory

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines how celebrity endorsements drive sustainable consumption by shaping purchase intentions for green moisturizers in China, integrating the Theory of Planned Behavior (TPB) and Source Credibility Theory (SCT). Surveying 700 consumers and applying partial least squares structural equation modeling (PLS‐SEM), we find celebrity ...

A Method for Assessing the Risks to Sustainability Posed by Process Operations

open access: yesSustainable Development, EarlyView.
ABSTRACT We present a framework for assessing the risks to sustainability posed by any given set of processes. The objective is to improve sustainability by enabling better decision‐making in policy and business contexts. The framework can be applied to any system of processes where available information supports discovery and quantification of ...

Vehicle Routing Problem

Transportation Research Record: Journal of the Transportation Research Board, 2013
The vehicle routing problem with simultaneous deliveries and pickups (VRPSDP) has attracted much research interest because of the potential to provide cost savings to transportation and logistics operators. Several extensions of VRPSDP exist. Of these extensions, the simultaneous deliveries and pickups with split loads problem (SDPSLP) has been ...

The Vehicle Routing Problem

SIAM monographs on discrete mathematics and applications, 2002
The Vehicle Routing Problem covers both exact and heuristic methods developed for the VRP and some of its main variants, emphasizing the practical issues common to VRP. The book is composed of three parts containing contributions from well-known experts. The first part covers basic VRP, known more commonly as capacitated VRP.
