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 کاملDemonstration of melorheostosis on bone scan
Background: Melorheostosis has been discussed infrequently in the nuclear medicine literature. A 25-year-old female patient presented with a one-year history of b:union: pain, sclerotic change and skin pigmentation on the left big toe interphalangeal joint. Ulceration, poor healing and hyperkeratoses of the wound were noted post debridement. The plain film of the left foot incidentally showed m...
متن کاملA honeycomb-like structure in the left anterior descending coronary artery: demonstration of recanalized thrombus by optical coherence tomography.
ippok at the n the A 41-year-old man presented with atypical chest pain in another hospital with an electrocardiogram negative for ischemia, but with slightly elevated troponin I levels (0.12 ng/ml). The patient underwent cardiac catheterization within 24 h. Coronary angiography revealed 2 nonsignificant lesions at the proximal left anterior descending (LAD) coronary artery and angiographic haz...
