Abstract Although substantial research work has been conducted in order to understand and improve the drilling of multi-material aerospace stacks, some key aspects related process tool parameters their impact on interface quality still need be addressed. This paper reports investigate point angle interlayer gap width borehole quality, focussing region. A number tests were carried out using tool...

Wheeled mobile robots are widely implemented in the field environment where slipping and skidding may often occur. This paper presents a self-adaptive path tracking control framework based on radial basis function (RBF) neural network to overcome slippage disturbances. Both kinematic dynamic models of wheeled robot with skid-steer characteristics established position, orientation, equivalent er...

This pandemic also affected the amount of costs incurred from teak harvesting process. Based on previous research, we tried to compare arising during pandemic. On other hand, Cost analysis community aims analyse by at each process, starting felling, skidding, transportation stages, both in self-managed systems and wholesale systems. Data were collected through observation interviews which then ...
