He was the first to devise an oscillating engine, of which he made a model about 1784; in 1786 he was busy with a steam carriage or road locomotive that was unsuccessful; and in 1799 he invented the long D slide valve.
If you wanted to spell "DOG", for example, you'd put your thumb down on D, slide it over to O, down to G, and then release.
Tajima's D sliding window analysis identified a strong negative peak within the promoter sequence of the FW2.2 gene.
When Chris Kalb, 35, of Brooklyn first tried to use his new -- well, 1952 -- 3-D slide projector, the image that appeared on his white wall was a jumbled mishmash.
It has the uncanny look of a 3-D slide show or some hybrid of photography and film; it also calls to mind the stereographic viewers that were popular in the 19th century.
(A-D) Slide shows the heart, kidney, liver and lungs of control mice.
For each pixel a 2-D sliding window of size is selected in such a way that the current pixel lies at the centre of the sliding window.
The performance of the proposed controller is found to improve with an increase in the fractional value of the derivative term in the FOPI-D sliding surface.
A modified SMC with a fractional-order PI-D (FOPI-D) sliding surface is also proposed, in which the output of the system is directly applied to the derivative term of the sliding surface equation.
A simulation study, carried out with set points above and below a threshold value, revealed that the proposed SMC with the FOPI-D sliding surface delivers better closed-loop performance than conventional SMC, SMC with FOPD and SMC with FOPID sliding surfaces.
