A case study for quantifying the benefits of coordinated actuated traffic signal systems provided cost estimates for upgrading a 2.4 mile arterial segment on Route 17 in Gloucester, Virginia from a non-coordinated system to a coordinated system. The net present value over 10 years for the system maintenance costs is $1,621.60 per year for the non-coordinated system and $2,434.40 per year for the coordinated system.
For example, consider a 10 mm-focal-length eyepiece of 50Â° apparent field in combination with a scope of 1,000 mm focal length. The magnification will be 100x (that is, 1,000/10) and the true field will be 50Â°/100x, or 0.5Â° â so the full Moon would just nestle within the field of view.
The magnification of a microscope describes the increase in apparent size of an object compared with its actual size. An object magnified 10 times (10X) appears 10 times larger than it really is. Total magnification is the product of the ocular lens magnification and the objective lens magnification. Magnification does not describe the quality of the image. Magnifying an object without good resolution is called empty magnification, as the image appears larger but no greater detail can be seen.
