The greater resolution that was achieved with a lake specific creel survey at Fremont lakes revealed a system of lakes with a large degree of spatial variation in angler effort and catch that would be missed by a coarser, system-wide survey that did not differentiate individual lakes.
Based on a coarse geographical system, ASTRA is a system dynamics model where the input/output relationships between sectors play a major role in explaining the linkages between transport, economy and environment.
Today, most SPM systems need to have both a coarse positioning system (using e. g. servomotors) and a fine positioning system, using piezoceramic components.
However, they also report evidence that going from a coarse information system to a precise information system decreases honesty in managerial reporting.
The coarse pore system hardly allows any capillary water ascent (Mensching 1990).
In such case, the coarse tracking system is employed to start again the initialization loop described beforehand.
As long as the coarse pointing system can keep the optical boresight to within these limits, the final pointing performance will be determined mainly by the fine pointing mechanism.
While a well-known PI controller was adopted to establish the coarse control system due to its simplicity and reasonable performance, a gain-scheduled H∞ controller was also employed to robustly ensure the desired accuracy of the fine control system.
