A Q4/Q4 continuum structural topology optimization implementation

A node-based design variable implementation for continuum structural topology optimization in a finite element framework is presented and its properties are explored in the context of solving a number of different design examples. Since the implementation ensures Ccontinuity of design variables, it is immune to elementwise checkerboarding instabilities that are a concern with element-based desi...

Linear blocking sets in PG(2, q4)

In this paper, by using the geometric construction of linear blocking sets as projections of canonical subgeometries, we determine all the GF (q)linear blocking sets of the plane PG(2, q).
