Abstract It is challenging to insulate sound transmission in low frequency-bands without blocking the air flow in a pipe.In this work, a Sealed Crimp Joiner Terminals small and light membrane-based cubic sound insulator is created to block acoustic waves in multiple low frequency-bands from 200 to 800 Hz in pipes.Due to distinct vibration modes of

This paper presents a virtual-force-based guidance law (VFGL) for path following and obstacle avoidance in unmanned aerial vehicles.First, a virtual spring force and a virtual drag force are designed for straight-line following; then, the dynamic of the cross-track-error is equivalent to a Pedestal Fans spring mass system, which is easy to tune to
A new halichondrid demosponge bubarid Ptilospongia hemisphaeroidalis gen.et sp.nov.is described from the latest Ordovician Beigong Biota in Jingxian County, Anhui Province, South China.The new taxon is well-preserved with a two-layer choanosomal skeleton structure (basal layer and erect monactines Sealed Crimp Joiner Terminals layer) and three diff
