Within a set-grammatical frame, multiple structures are determined for a line by using an object - feature approach. The Galois connection and its related lattice is employed. Most 'world-pictures' of the line are not Boolean.

An <I>N</I>-omino is a planar edge-connected set of <I>N</I> square cells. The terms polyomino (<I>N</I>-omino) and animal are equivalent, the first attributable to Golomb (1954) and the latter to Read (1962). This paper presents some results derived from a census of three different populations of <I>N</I>-ominoes for <nobr><I>N</I> =...</i></nobr></i></i></i></i>

This paper seeks to extend the macrostatic approach to urban modelling by treating modelling problems as many-stage processes. Within such a process the early stages are concerned with explaining the relatively trivial characteristics of the phenomena of interest, and the later stages are...

An algorithmic structure for design is postulated.

With the intention of reevaluating proportion theory in design, I provide here a grounding for a pictorial approach to the anthyphairetic procedures of Platonic mathematics.
