Home and away: allometry and climate drive morphology of European rabbits in their native and introduced range

Oikos, EarlyView.
Climatic conditions shape phenotypic evolution by driving adaptations that optimise organismal function. Invasive species provide valuable systems to study these processes, as they often encounter novel climatic conditions in their introduced ranges. The European rabbit Oryctolagus cuniculus, native to the Iberian Peninsula, has established populations

Analysis of the suitability of using the selected wind turbine blades for wind power appliances based on numerical analyses

E3S Web of Conferences, 2018
The aim of this study was a comparative analysis of the suitability of the use of airfoil for wind power. Based on numerical analyses and analytical methods, information on the power factor was obtained. The analyses were carried out for the wind turbine

Wind Predictions Upstream Wind Turbines from a LiDAR Database

Energies, 2018
This article presents a new method to predict the wind velocity upstream a horizontal axis wind turbine from a set of light detection and ranging (LiDAR) measurements. The method uses higher order dynamic mode decomposition (HODMD) to construct a reduced

Behavior of a Novel Cyclic Olefin‐Based Hot‐Melt Adhesive in CFRP Adhesive Joints Compared to Conventional Epoxy‐Based Structural Adhesives

Polymer Composites, EarlyView.
Rate‐dependent performance of composite adhesive joints using thermoset and thermoplastic adhesives, in terms of toughness and fatigue behaviour. ABSTRACT A recently developed hot‐melt adhesive (HMA) based on cyclic olefin chemistry, supplied as a transparent, non‐tacky thermoplastic film with a distinctive polymer microstructure, was evaluated in this

A Review of Mechanical Reinforcement and Piezoresistive Self‐Sensing in Carbon Nanotube Fiber Composites

Polymer Composites, EarlyView.
PSPP‐TRL mapping of CNT‐modified CFRP literature, with four recurring confusions resolved and five scale‐up problems quantified. ABSTRACT Carbon nanotube‐modified fiber composites are often presented as a route to stronger, tougher, and self‐sensing structural materials.

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

Journal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

Numerical Simulation of Aerodynamic Performance of Off-grid Small Vertical Axis Wind Turbine

E3S Web of Conferences, 2018
In this paper, a 2D off-grid small compact model of vertical axis wind turbine was established. The sliding grid technology, the RNG turbulence model and the Coupld algorithm was applied to simulate the unsteady value of the model's aerodynamic ...

Unmanned Aerial Systems for Corrosion Detection: Multi‐Sensor Technologies, Challenges, and Opportunities for Next‐Generation Inspection

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Corrosion remains a critical threat to the integrity and service life of infrastructure in industries such as oil, gas, construction, renewable energy, and transportation. Traditional inspection methods, being labor‐intensive, hazardous, and often subjective, fall short in addressing modern inspection demands.
