This paper analysises the reason of losing step or crawling when step motor accelerate or decelerate,and introduces a method to accelerate or decelerate the speed of step motor controlled by singlechip following S curve.
Growth trend,leaf area formation,podding characteristics and pod yield formation of dwarf asparagus bean sowed in spring and autumn in Guangzhou were studied. The results showed that the growth trends of plant and its organs (root,stem,leaf and pod) appeared in S curve when sowed in spring.
The standard hemolysis and hemolytic increment curve of the hypothyroid group drawn according to osmotic fragility test results was found to be shifted to the right when compared to control group's curve.
Using Tocher's curve to convert subjective quantile-estimates into a probability distribution function
An alternative procedure using "Tocher's curve" is proposed, and its performance is evaluated with a wide variety of test distributions.
A new method for testing pile by single-impact energy and P-S curve
It is educed accordingly that the force P and displacement S are calculated from the amplitude of wave train and (dynamic) P-S curve is drew so as to determine the yield points.
In practice, the problem is mainly solved by using the so-called S-shape heuristic in which orderpickers move in a S-shape curve along the pick locations.
Correspondingly, the plots of negative logarithm of apparent dissociation constant (pKa) against α showed a reversed S-shape curve over the whole α, indicating an extensive precipitation and subsequent tran-sition from compact to coiled conformation.
The similar S-shape curve of JSC-1 is probably a result of the Fe-Ti oxides and Cr-spinel.
