background: a variable resolution x-ray (vrx) ct scanner provides a great increase in the spatial resolution. in vrx ct scanners, the spatial resolution of the system and its field of view (fov) can be changed according to the object size. one of the main factors that limit the spatial resolution of vrx ct scanner is the effect of the x-ray focal spot. materials and methods: a theoretical study...

Regional planning model is critical for the planning support system employed by Metropolitan Planning Organization (MPO). As an example of regional planning model, Southern California Planning Model (SCPM) incorporates economic input-output analysis to a spatial allocation model and reports results in considerable spatial detail. The economic inputoutput model is used to estimate the indirect a...
