Effect of Build Orientation on the Electrical, Thermal, and Mechanical Properties of PA12 Fabricated by Selective Laser Sintering

Selective laser sintering (SLS) provides a promising route for the rapid fabrication of polymeric insulating components with complex geometries. However, its layer-by-layer manufacturing process inherently introduces structural anisotropy, which may significantly affect the elect...

Dynamic characteristics of tower response of a FOWT under wind-wave misalignments and mooring line failures

Floating offshore wind turbines (FOWTs) enable energy harvesting from shallow and deep-water regions with high wind potential. However, the structural performance of their towers is sensitive to wind–wave misalignment and mooring line failure. This study investigates the tower re...

Experimental study on gas fracturing behavior of damaged basalt in compressed air energy storage caverns

Compressed air energy storage (CAES) caverns excavated in hard rock experience repeated mechanical disturbance during construction and cyclic gas pressurization during operation, which may progressively degrade surrounding rock and influence fracture stability. To investigate gas...

Atomic-Scale Adjustment of Modified Natural Ester Molecules Related to Electrical and Physical Properties

Abstract Cooling efficiency and thermo-oxidative stability remain major challenges for vegetable-oil-based dielectric fluids. Here, soybean oil (SBO) was modified by transesterification with short-chain alcohols, and the effects of terminal alkyl-chain length were examined using...

Multi-body dynamics and Gyro-MPC-DOB based trajectory tracking control of live-line working robot

When the Live-line working robot carries out high-altitude operations, uncertainty factors such as external wind disturbance, end-load variations, and body vibration affect the control performance of the robotic arm, resulting in poor trajectory tracking accuracy of the robotic a...

Research on trajectory prediction and tracking methods for underwater cleaning robots based on PA-MDP

To address cleaning operations in high-interference power cooling ponds, this paper proposes a physics-aware Markov decision process (PA-MDP) framework. This framework is designed to mitigate trajectory deviations caused by the decoupling of decision-making logic and physical dyn...
