Honeycomb Arrays
A honeycomb array is an analogue of a Costas array in the hexagonal grid; they were first studied by Golomb and Taylor in 1984. A recent result of Blackburn, Etzion, Martin and Paterson has shown that (in contrast to the situation for Costas arrays) there are only finitely many examples of honeycomb arrays, though their bound on the maximal size of a honeycomb array is too large to permit an ex...
متن کاملHoneycomb Subdivision
In this paper, we introduce a new subdivision scheme which we call honeycomb subdivision. After one iteration of the scheme each vertex becomes exactly 3-valent and with consecutive applications regular regions strongly resembles a honeycomb. This scheme can be considered as a dual for triangle schemes. The major advantage of the new scheme is that it creates a natural looking mesh structure.
متن کاملHoneycomb Topologies
An increased use of free form surfaces in design often results to mass customised components and structural systems which are complex to assemble and expensive to produce. Often to resolve these forms, a tessellation algorithm is used to break the geometry down to manageable components which can be fabricated individually. The issue that can arise is the production of ...

متن کاملHoneycomb nanogold networks with highly active sites.
The formation of macroporous honeycomb gold using an electrochemically generated hydrogen bubble template is described. The synthesis procedure induces the formation of highly active surfaces with enhanced electrocatalytic and surface enhanced Raman scattering properties.
