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, m, is defined as the ratio of the image height to the object height, which is closely related to the ratio of the image distance to the object distance: A magnification of 1 (plus or minus) means that the image is the same size as the object.f m has a magnitude greater than 1 the image is larger than the object, and an m with a magnitude less than 1 means the image is smaller than the object. If the magnification is positive, the image is upright compared to the object; if m is negative, the image is inverted compared to the object.
