Abstract The Debye sheath is known to vanish completely in magnetised plasmas for a sufficiently small electron gyroradius and angle between the magnetic field wall. This depends on current onto When vanishes, there still potential drop wall plasma across presheath. corresponding predicted collapse shown be much smaller than previous estimates, scaling with electron-ion mass ratio not square ro...

This paper presents two novel methods for Angle-of-Arrival (AoA) estimation in the presence of unknown mutual coupling. We mainly focus on the first method, where we show that this method could estimate AoAs of multiple sources when more mutual coupling parameters are included in the model, compared to existing methods. Furthermore, we derive a closed form Mean-Squared-Error (MSE) expression of...

Nanocrystal bonding is an important phenomenon in crystal growth and nanoscale welding. Here, we show that for gold nanocrystals bonding in solution can follow two distinct pathways: (1) coherent, defect-free bonding occurs when two nanocrystals attach with their lattices aligned to within a critical angle; and (2) beyond this critical angle, defects form at the interfaces where the nanocrystal...

This paper presents buckling studies made on skew plates using finite element. The effects of the skew angle, aspect ratio, length-to-thickness-ratio, fibre orientation angle, and numbers of layers in the laminate and laminate sequence on the critical buckling load factor (Kcr) of antisymmetric composite laminates have also been presented. The critical buckling load factor (Kcr) is found to inc...
