tailieunhanh - Agent-based and analytical modeling to evaluate the effectiveness of greenbelts

The goal of this project is to learn about the visual qualities that can be used to control aesthetics in visualization. Psychologists have identified emotional and cognitive properties believed to underlie the aesthetic judgement of images. Based on this work, I have chosen three visual qualities that appear promising to aesthetics in visualization. I propose to vary these qualities and conduct studies to evaluate the salience of each quality in terms of aesthetics. Statistical analysis will be used to detect any significant changes in aesthetic judgement or related properties. Finally, these insights will be applied to visualizations and these will be tested in an application setting | Available online at Environmental Modelling Software ELSEVIER Environmental Modelling Software 19 2004 1097-1109 locate envsoft Agent-based and analytical modeling to evaluate the effectiveness of greenbelts Daniel G.

First we develop a mathematical model under two assumptions about the distributions of service centers that represents the trade-off between greenbelt placement and width their effects on the rate of development beyond the greenbelt and how these interact with spatial patterns of aesthetic quality and the locations of services. Next we present three agent-based models ABMs that include agents with the potential for heterogeneous preferences and a landscape with the potential for heterogeneous attributes. Results from experiments run with a one-dimensional ABM agree with the starkest of the results from the mathematical model strengthening the support for both models. Further we present two different two-dimensional ABMs and conduct a series of experiments to supplement our mathematical analysis. These include examining the effects of heterogeneous agent preferences multiple landscape patterns incomplete or imperfect information available to agents and a positive aesthetic quality impact of the greenbelt on neighboring locations. These results suggest how width and location of the greenbelt could help determine the effectiveness of greenbelts for slowing sprawl but
