MODELLING OF WORK EFFICIENCY IN CABLE TRACTION WITH TRACTOR IMPLEMENTING THE LEAST-SQUARES METHODS AND ROBUST REGRESSION

Wood-harvesting activities are conducted by contractors through tendering based on prices determined by the amount of transported wood, land conditions and transport method parameters.Managers should determine the average completion time of the work and the base price accurately to prevent both work and contractor losses prior to the tender and not

Acoustic emission technology has been applied to many fields for many years.However, the conventional piezoelectric acoustic emission sensors cannot be used in extreme environments, such as those with heavy electromagnetic interference, high pressure, or strong corrosion.In this paper, a novel fiber-optic ring acoustic emission sensor is proposed.T
