Land use and transportation interaction is a complex, dynamic process. Many models have been used to study this interaction process during the past several decades. Empirical studies suggest that land use and transportation interaction patterns can be highly variable between geographic areas and at different spatial and temporal scales. This paper presents(More)
While GIS (Geographic Information Systems) are equipped with exploratory analysis for spatial patterns, there are few tools available for the analysis of spatio-temporal data in terms of their spatial patterns and temporal patterns. Temporal GIS is proposed addressing the need by providing a promising method to explicitly reveal characteristics at a(More)
Z-slots are presumed to offer a structural advantage over conventional inclined slots for narrow wall slotted waveguide antennas, in that the corners of the rectangular waveguide are not cut and consequently will not weaken a structural tube as much. Initial structural simulations are shown to confirm this assumption. This slot configuration was also(More)
