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.
Eyepieces have focal lengths, too â 25- or 10-mm, for example. To calculate the magnification, simply divide the focal length of the scope by that of the eyepiece. A 2000-mm focal length scope used with a 25-mm eyepiece will therefore deliver 2000/25 = 80 power (or 80x).
Magnification is the increase (or decrease) in size of an image produced by an optical system compared to the true size.The most commonly considered form of magnification is linear magnification, although angular magnification is sometimes also encountered.hen the (linear) magnification is defined by.
