A Resource Allocation Scheme in Half Duplex FDD (H-FDD) Systems for M2M Communications

open access: yesIFAC Proceedings Volumes, 2013
Abstract Machine to machine (M2M) communications among machines without human intervention have attracted more and more prominence due to high market potential in the near future. In this article, we propose a heuristic algorithm of allocating weighted per-user data rates for half duplex frequency division duplexing (H-FDD), and show how much ...

AI in chemical engineering: From promise to practice

open access: yesAIChE Journal, EarlyView.
Abstract Artificial intelligence (AI) in chemical engineering has moved from promise to practice: physics‐aware (gray‐box) models are gaining traction, reinforcement learning complements model predictive control (MPC), and generative AI powers documentation, digitization, and safety workflows.

Warming Leads to Biomass Increase, Leaf Nitrogen Decline, and Community Turnover in Mediterranean Nardus stricta Grasslands [PDF]

open access: yesEcol Evol
Experimental warming in Mediterranean subalpine Nardus stricta grasslands increased plant biomass and species richness. However, it drove community turnover, reduced the abundance of cold‐adapted endemics, and lowered leaf nitrogen content, indicating declining forage quality.

Adaptive Signal Processing Strategy for a Wind Farm System Fault Accommodation [PDF]

open access: yes, 2018
In order to improve the availability of offshore wind farms, thus avoiding unplanned operation and maintenance costs, which can be high for offshore installations, the accommodation of faults in their earlier occurrence is fundamental.

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

open access: yesThe Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Flow-diverting devices in the treatment of unruptured ophthalmic segment aneurysms at a mean clinical follow-up of 5 years

open access: yesScientific Reports, 2021
A shift toward the endovascular treatment of ophthalmic segment aneurysms is noticeable. However, it is not clear if the long-term treatment results improve with the development of endovascular methods.

Real‐Time Data‐Driven Fault Diagnosis of Photovoltaic Arrays Using an Edge‐Server Machine‐Learning Framework

open access: yesEnergy Science &Engineering, EarlyView.
A real‐time, data‐driven framework detects and classifies photovoltaic array faults using edge sensing and server‐side machine learning. Ensemble tree models achieve near‐perfect accuracy with low latency, enabling practical, low‐cost deployment for reliable PV monitoring and intelligent maintenance.

Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).
