There are two types of stall-warning devices commonly used on light aircraft. The warning is actuated when the vane is blown up and forward. At low angles of attack e. As the angle of attack increases, the stagnation line moves farther and farther aft underneath the wing.

Introduction Sharpness is arguably the most important photographic image quality factor because it determines the amount of detail an imaging system can reproduce. Sharpness is defined by the boundaries between zones of different tones or colors.

It is illustrated by the bar pattern of increasing spatial frequency, below. The top portion is sharp; its boundaries are crisp steps, not gradual.

The bottom portion illustrates how the pattern is degraded after it passes through a lens. All lenses, even the finest, blur images to some degree. Poor lenses blur images more than fine ones. Although rise distance is a good indicator of image sharpness, it has an important limitation.

There is no simple way to calculate the rise distance of a complete imaging system from the rise distance of its components— from a lens, digital sensor, and software sharpening. To get around this problem, measurements are made in frequency domain, where frequency is measured in cycles or line pairs per distance millimeters, inches, pixels, or image height.

The image below is a sine wave— a pattern of pure tones— that varies from low to high spatial frequencies. The top portion is the original sine pattern.

The bottom portion illustrates lens degradation, which reduces pattern contrast at high spatial frequencies. It is the key to measuring sharpness.

Sine and bar patterns, amplitude plot, and Contrast MTF plot The upper plot displays the sine pattern with lens blur the original bar pattern the bar pattern with lens blur Lens blur causes contrast to drop at high spatial frequencies.

Contrast decreases at high spatial frequencies. The modulation of the sine pattern which consists of pure frequencies is used to calculate MTF. The lower plot displays the corresponding sine pattern contrast, i.

Amplitude is displayed on a linear scale. Green is for geeks. Do you get excited by a good equation? Were you passionate about your college math classes?Algebra > Lines > Finding the Equation of a Line Given a Point and a Slope.

In the last lesson, I showed you how to get the equation of a line given a point and a slope using the formula.

Find the equation of the line that passes through (1, -5) and is parallel to. As we have in each of the other examples, we can use the point-slope form of a line to find our equation. We are given the point, but we have to do a little work to find the slope. We know we are looking for a line parallel to.

From the table we see that 1 mole of water has a mass of grams, which isn't very much (about the mass of water in a couple of small ice-cubes you'd make in your family freezer).
