Classical unification is strict in the sense that it requires a perfect agreement between the terms being unified. In practice, data is seldom error-free and can contain incorrect information. Classical unification fails when the data is imperfect. Fuzzy unification partially addresses uncertainty but requires the creation of fuzzy databases. We propose relaxed unification as a new theory that relaxes the Ugg Boots Sale Online Canada constraints of classical unification without requiring special preprocessing of data. The goal of relaxed unification is to tolerate possible errors and inconsistencies in the data and facilitate reasoning under uncertainty. A technique is described for measuring the net canopy photosynthesis of crop stands over periods of 10 min in a near airtight, daylit controlled-environment cabinet. The accuracy of control of the CO2, concentration in the cabinet is usually within ±0.5% of the desired value. The amounts of CO2 used in crop photosynthesis are measured with a linear mass flowmeter accurate to within ±10 mg Ugg Boots Women CO2. The total errors incurred in measuring net rates of canopy photosynthesis are estimated to be of the order of 0.75% to ± 2.5%.Records from preliminary trials on tomato in the cabinet are presented as an example of what can be achieved experimentally with the technique.
