The hexagon theorem

IEEE Transactions on Information Theory, 1982
We wish to \int_{S}|Z-f(Z)|^{2},S the unit square, over all choices of f(Z) which take just n values. For large n it is shown that f(Z) approaches that function which on each face of a "hexagonal mesh" has the value of the centroid of that face. This problem in the design of quantizers for a pulse-code modulation (PCM) system arose in which pairs of ...

Hexagonal Silicon Realized

Nano Letters, 2015
Silicon, arguably the most important technological semiconductor, is predicted to exhibit a range of new and interesting properties when grown in the hexagonal crystal structure. To obtain pure hexagonal silicon is a great challenge because it naturally crystallizes in the cubic structure.

A Hexagon Sensor and A Layer-Based Conversion Method for Hexagon Clusters

open access: yesInformation (Switzerland)
In reinforcement learning (RL), precise observations are crucial for agents to learn the optimal policy from their environment. While Unity ML-Agents offers various sensor components for automatically adjusting the observations, it does not support ...

Doyen–Wilson theorem for perfect hexagon triple systems

open access: yesDiscrete Mathematics, 2011
The graph consisting of the three 3-cycles (or triples) (a,b,c), (c,d,e), and (e,f,a), where a,b,c,d,e and f are distinct is called a hexagon triple.

Hexagonal Mesoporous Germanium

Science, 2006
The blending of mesoporosity with the properties of semiconductors promises new types of multifunctional nanomaterials. It would be particularly interesting to combine the shape selectivity of a mesoporous oxide with the electronic and photonic characteristics of a useful semiconductor.

Hexagonal Systems, I

2002
In this chapter, we give the classification of hexagonal systems as formulated in Theorem 17.6. Our goal is to show that the list of hexagonal systems described in (15.14) and summarized in Figure 2 on page 148 is complete.

The Munificent Hexagon

Simulation & Games, 1973
Abstract The Munificent Hexagon is an oral gaming-examination that generates avid participation on the part of the student and stimulates intense interaction between instructor and student. This is seen to be an important antidote to the anonymity threatening academia.
