| Air compressed on the upstroke helps push the piston back down, minimizing energy loss. |
|
| The backward tilt of the stroke plane elevates flight force during the upstroke by increasing the aerodynamic angle of attack. |
|
| As with the arterial pressure wave, a normal pulse volume tracing has a brisk upstroke and a dicrotic notch. |
|
| In putting, should you hit the ball on the upstroke, on the downstroke or at the bottom of the stroke? |
|
| In bats and birds in air, lift is generated by the upstroke at high flight speeds, but not at low speeds. |
|
| Thus, lift forces exerted on the hindlimbs may explain why bats inspire during the downstroke of their wings and expire during the upstroke. |
|
| The problem here is that the upstroke should be as fast as the downstroke: this problem appears at fast tempos. |
|
| Lift during upstroke is almost always described as small compared to that during the wing downstroke. |
|
| This is because the upstroke is on a downbeat and because the pace is really fast. |
|
| This spring must be positioned in a fashion that it is tensioned at the upstroke. |
|
| Dual depth stop for complete control of both down stroke depth and upstroke travel. |
|
| The basic version can also be enriched with a swinged upstroke just before the first beat. |
|
| However, in films of murres underwater, relative upstroke speed and thrust appear to be greater during vertical descent against high buoyancy than during horizontal swimming. |
|
| In flight, cranes and the limpkin have a characteristic wing action a slow downstroke followed by a quick, flicking upstroke. |
|
| The strongest vortex came from the wing's tip and lasted through the end of each upstroke made by the bats. |
|
| To avoid the additional drag during upstroke, lift is mostly required in the wing area near the fuselage only. |
|
| Pulling or dragging of the outboard wing section during upstroke by the inboard wing section. |
|
| The filling volume is adjustable as per upstroke and down stroke of the disk position. |
|
| Its function is to facilitate the upstroke of the tomato on the loading belt. |
|
| But at the wing upstroke the air flow hits the wing rather from above and at downstroke rather from bottom. |
|
|
|
| Rayner et al. suggested that in both bats and birds flying in air, wingbeat gaits are in fact defined by upstroke function, which varies with wing morphology. |
|
| The total thrust effect of the upstroke thereby equals zero. |
|
| For example, birds clap their wings together at the peak of the upstroke during takeoff — that's the clatter of a pigeon taking off in the park — and rotate their wings on the way down to get lift. |
|
| Vented area for hydrodynamic superior flow during upstroke. |
|
| This feature produces a thick downstroke and a thin upstroke with infinity of gradation in between. |
|
| Usually saws were designed to cut on the down stroke, so the lower man in the saw pit pulled the saw, while the upper man lifted the blade up and out on the upstroke. |
|
| A good way to decrease the wind turbine effect in spite of strong lift generation is the pulling or the dragging of the outboard wing section during the upstroke of the inboard wing section. |
|
| The second derivative of the forestream signal marks exactly the beginning of the upstroke of the pulse wave. |
|
| Starting from the previously described flight scenario for the horizontal cruising flight it is more advantageous to increase the total lift at the upstroke and shift it a little more towards the wing tip. |
|
| By folding the wings in toward their bodies on the upstroke, they save 35 percent energy during flight. |
|
| Cycle refers to combination of one upstroke and one downstroke. |
|
| The major effect of the feather is to fan as the wing opens and closes, and in flight they pivot as the wing is pulled into the upstroke of a flap. |
