Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Women Are Eco‐Friendly, so Are They From Venus? Exploring Green‐Feminine Stereotyping and Green Gender Gap

Business Strategy and the Environment, EarlyView.
ABSTRACT Marketers and policy makers have tried to bridge the green attitude–behavior gap through the use of pro‐environmental appeals using advertising to convey the “greenness” of their products. However, due to green‐feminine stereotyping, by focusing mainly on the green characteristics of the product, we may have alienated men, who, to safeguard ...

Inverse Simulation as a Tool for Fault Detection and Isolation in Planetary Rovers [PDF]

, 2017
With manned expeditions to planetary bodies beyond our own and the Moon currently intractable, the onus falls upon robotic systems to explore and analyse extraterrestrial environments such as Mars. These systems typically take the form of wheeled rovers,

Analysis of driving performance evaluation for an unmanned tractor

IFAC-PapersOnLine, 2018
Abstract Rural labor force has been gradually decreased due to decreasing of farm population and increasing of aging population. Therefore, the study of unmanned technology is needed to overcome labor shortage in agriculture. These days most research on unmanned autonomous tractors has been carried out through field tests; however, field tests ...

Electronic Resonance Network Stabilized Crystal Structure in High‐Nickel Cathodes for Lithium‐Ion Batteries

Carbon Energy, EarlyView.
Transition metal (TM) ions with empty eg orbitals induce single‐electron delocalization in Ni3+ to form the resonance structure of Ni─OO─TM through the high‐entropy effect. High‐nickel cathode materials with electron resonance structure have the advantages of improving thermodynamic stability, suppressing phase transitions, and mitigating lattice ...

Real‐time lithology identification while drilling based on drill cuttings image analysis with ensemble learning

Deep Underground Science and Engineering, EarlyView.
A lithology identification while drilling method was developed, integrating an automated cuttings sampling system, a smart drilling rig, and an ensemble learning model. Underground trials achieved 97.42% accuracy in real‐time identification of cuttings lithology and composition, enhancing hazard management and supporting unmanned drilling technology in

Interfacial Solvent Molecular Engineering via High‐Safety Dense Separators for High‐Rate Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The dense PPS‐separator prevents thermal runaway by allowing electron transfer through the steel needle during penetration, while the residual electrolyte enables brief ion migration and Joule heating, causing rapid electrolyte vaporization, collapse of the ion transport network, and a sharp drop in ionic conductivity.

Superior through‐plane thermal conductivity in carbon fibers/spherical graphene/epoxy laminated composites for low‐altitude aircrafts

InfoMat, EarlyView.
To address the low through‐plane thermal conductivity (λ⊥) of carbon fiber/epoxy composites, which poses thermal management challenges in the expanding low‐altitude economy, we incorporated spherical thermally reduced graphene (s‐TRG) as a bridging filler. This architectural design achieved a λ⊥ of 2.73 W m–1 K–1 at 10 wt% loading.
