    • Boundaries and Topological Algorithms 

      Fleck, Margaret Morrison (1988-09-01)
      This thesis develops a model for the topological structure of situations. In this model, the topological structure of space is altered by the presence or absence of boundaries, such as those at the edges of objects. ...
    • Local Rotational Symmetries 

      Fleck, Margaret Morrison (1985-08-01)
      This thesis describes a new representation for two-dimensional round regions called Local Rotational Symmetries. Local Rotational Symmetries are intended as a companion to Brady's Smoothed Local Symmetry Representation ...
