From liquid learning to weaving learning: Negotiating meanings of Children's learning in family travel

British Educational Research Journal, EarlyView.
Abstract Children's learning increasingly extends into everyday informal settings, but what counts as learning in these contexts remains insufficiently understood. Focusing on family travel as a mobile and socioculturally situated informal learning context, this study adopts a sociocultural perspective and uses liquid learning as a sensitising concept ...

ALD Derived Li2O Layer Stabilizing Solid Electrolyte Interphase of Silicon/Carbon Anodes for Lithium Storage

Carbon Energy, EarlyView.
A durable solid electrolyte interphase (SEI) is essential for mitigating the mechanical fracture and interfacial instability of silicon anodes under strong electrochemical‐mechanical coupling. Herein, a uniform Li2O layer was accurately deposited on the Si/C composites to regulate the growth characteristics of SEI.

Development and Implementation of Physics-Informed Neural ODE for Dynamics Modeling of a Fixed-Wing Aircraft Under Icing/Fault

Guidance, Navigation and Control
Accurate dynamics modeling is crucial for the safety and control of fixed-wing aircraft under perturbation (e.g. icing/fault). In this work, we propose a physics-informed Neural Ordinary Differential Equation (PI-NODE)-based scheme for aircraft dynamics ...

Inflight Parameter Identification and Icing Location Detection of the Aircraft: The Time-Varying Case

Journal of Control Science and Engineering, 2014
This paper considers inflight parameter identification and icing location detection of the aircraft in a more common time-varying nature. In particular, ice accumulation is modeled as a continuous process, and the effect of the ice upon aircraft dynamics

Spatio‐temporal dynamics of ringed seal density and habitat use in the Arctic's Last Ice Area

Ecography, EarlyView.
The Arctic is warming at approximately four times the global rate, driving widespread decline in sea ice extent, thickness, and seasonal duration. The ecological consequences of these rapid changes remain poorly understood within the Last Ice Area, a region that includes northern Ellesmere Island and the northwest of Greenland, projected to retain ...

Cloud icing by mineral dust and impacts to aviation safety

Scientific Reports, 2021
Ice particles in high-altitude cold clouds can obstruct aircraft functioning. Over the last 20 years, there have been more than 150 recorded cases with engine power-loss and damage caused by tiny cloud ice crystals, which are difficult to detect with ...

Effect of Water Temperature on Ice Adhesion Strength Based on Nucleation Theory

Hangkong gongcheng jinzhan, 2022
Aircraft icing will affect flight safety and even lead to serious flight accidents. Studying the adhesion strength between icing and substrate can provide specific index requirements for the design of aircraft anti-icing and de-icing system.

Flight safety warning of iced aircraft based on reachability analysis and fuzzy inference

Measurement + Control
A flight safety warning method based on reachability analysis and fuzzy inference is proposed against aircraft icing. A nonlinear model of iced aircraft with uncertainty is proposed based on the existing research results on the effects of icing and the ...
