In this paper we show how the dynamic behavior of human actors and their influence on land use change can be modeled to produce spatially explicit simulations of future land use. An actor-based dynamic systems approach is integrated with the existing APoLUS (Actor, Policy and Land Use Simulator) cellular automata land use model. Previous versions of APoLUS determined final total land use amount...

Plan formulation and plan comprehension in adversary situations constitute integral components of human reasoning. A process model based on heuristic strategies is presented for decision making in obstructive and constructive counterplanning situations. The former situation is characterized by an actor striving to thwart the goals and plans of a second actor. The latter is the dual situation; i...

This paper presents a novel representation for human actions which encodes the variations in the shape and motion of the performing actor. When an actor performs an action, at each time instant, the outer object boundary is projected to the image plane as a 2D contour. A sequence of such contours forms a 3D volume in the spatiotemporal space. The differential geometric analysis of the volume su...
