Causal analysis of extreme risk in a network of industry portfolios

Canadian Journal of Statistics, EarlyView.
Abstract We provide a detailed review of causal dependence within the framework of max‐linear structural models. Such models express each node variable as a max‐linear function of its parental node variables in a directed acyclic graph (DAG) and some exogenous innovation.

Self‐Maintained Thermal Charging Cells for the Efficient Harvesting of Waste Heat at Elevated Temperatures

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Thermal charging cells (TCS) face two main challenges that limit their practical applications: 1) Still lacking the systems suitable for operation under higher temperature environments, and 2) there are limitations in the self‐sustaining performance of continuous discharge under temperature differences, which holds critical significance for the real ...

Research on Thermal Runaway Multiphysics Coupling Simulation and Sensor Optimization Layout of Lithium Iron Phosphate Energy Storage Battery Packs

Energy Science &Engineering, EarlyView.
This study explores thermal runaway in lithium‐iron‐phosphate energy storage battery packs through multi‐physics coupling simulation. Thermal runaway evolves from battery cells (experiencing overcharge, bulging, safety valve opening, and gas venting) to battery clusters (a) and propagates within the battery pack (b). Simulation results indicate: stress

Design of HAWT Rotor for Non‐Uniform Inflow Conditions: A Theoretical and Experimental Approach for Shear Flow

Energy Science &Engineering, EarlyView.
This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.

Dynamic Modeling and Simulation of Morphing Wing Aircraft Considering Rigid‐Elastic Coupling Effects

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT During the morphing process, the dynamic modeling of the morphing wing aircraft presents the characteristics of rigid‐elastic coupling effects, moving boundaries, and low computational efficiency. Meanwhile, parameters such as aerodynamic forces/moments, center of pressure, center of mass, and moment of inertia would also change significantly,

Mechanical and Electrochemical Performance of a PETEA‐Based Solid‐State Electrolyte for Multifunctional Structural Battery Composites

Nano Select, EarlyView.
Multifunctional structural battery composites can store electrical energy while bearing mechanical loads, thereby reducing parasitic mass and volume. We present a novel solid‐state PETEA‐based electrolyte, which can be cured in situ after infiltration into the reinforcement fibers in its monomer form.

Impact and Post‐Impact Properties of Carbon Fiber Fabric Laminates Reinforced With Carbon Nanofibres

Polymer Composites, EarlyView.
Carbon nanofiber addition on the low‐velocity impact response of carbon fiber laminates. ABSTRACT The use of carbon fiber reinforced polymers (CFRPs) is limited by their susceptibility to low‐velocity impact (LVI) damage. This study investigates the effect of incorporating 0.75 wt.% carbon nanofibres (CNFs) into the epoxy matrix of carbon fiber fabric ...
