Analysis of a probing control strategy [PDF]

open access: yesProceedings of the 2003 American Control Conference, 2003., 2004
In this paper we analyse an extremum controller based on a pulse technique. The idea is to superimpose probing pulses to the control signal and use for feedback the size of the pulse response in the output. The probing control strategy has been used with success for the control of the substrate feeding in E. coli cultivations. The analysis is done here

STRATEGIES FOR THE CONTROL OF TRACHOMA [PDF]

open access: yesAustralian and New Zealand Journal of Ophthalmology, 1987
Abstract Trachoma is still a major cause of blindness in many developing areas. Trachoma can be viewed as a community‐based disease, and treatment or intervening strategies must be aimed at the community level. The more conventional approaches of treatment using either topical or systemic antibiotics do not seem to offer an appropriate cost‐benefit ...
