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.
Field of view Vs magnification. Let's start with the basic facts. Magnification at the image plane is the same with a 100mm lens whether it's on a DSLR, a 35mm camera, a 6x7 camera or a large format camera. Magnification is measured at the image plane, not on the print.
