This research addresses the obstacle avoidance problem in wheeled mobile robots powered by renewable energy by considering all subsystems involved.A Industrial:Restaurant three-tier hierarchical controller is developed, integrating the technique of artificial potential fields.The proposed controller incorporates the dynamics of the three key subsys
Protocols used to collect fish skin mucus may inadvertently compromise the sampled fish or the resulting sample.Here, we used three methods (wiping, scraping, and absorption) to collect skin mucus Outdoor Rug from Atlantic salmon and compared their invasiveness on fish skin epithelium.We found that the absorption method was the least invasive.We al
Real-world topological semimetals typically exhibit Dirac and Weyl nodes that coexist with trivial Fermi pockets.This tends to mask the physics of the relativistic quasiparticles.Using the example of ZrTe$_5$, we show that strain provides a powerful tool for in-situ tuning Eye Gels of the band structure such that all trivial pockets are pushed far
Fractures are widely distributed in coal, and studying the seepage characteristics of fluids in fractures is of great significance for unconventional natural gas extraction and prevention of gas disasters.In this work, based on the W-M fractal function, a Y-shaped fracture model with different roughness is established.The seepage characteristics of
