Research on Adaptive Control of Air-Borne Bolting Rigs Based on Genetic Algorithm Optimization

open access: yesMachines, 2021
Rotation speed and propulsive force are the two critical parameters in the work of the air-borne bolting rig. To address the problem that unreasonable rotation speed and propulsive force will induce the breakage of the drill pipe and the inability of the

Loads and loads and loads: the influence of prospective load, retrospective load, and ongoing task load in prospective memory [PDF]

open access: yesFrontiers in Human Neuroscience, 2015
In prospective memory tasks different kinds of load can occur. Adding a prospective memory task can impose a load on ongoing task performance. Adding ongoing task load (OTL) can affect prospective memory performance. The existence of multiple target events increases prospective load (PL) and adding complexity to the to-be-remembered action increases ...
