A Different Facet

A Facet of America's Greatness

inerica has been called a nation of joiners . We are. I don't know that anyone has ever made an exact count of all the voluntary organizations and associations in the United States, but my guess is that there must be a million or more . Upon coming to Norman a few years ago, I learned that there were over two hundred and fifty organizations in this community of modest size . I was particularly ...

Flat-surface, step-edge, facet–facet, and facet–step diffusion barriers in growth of a Pb mesa

Not Every GTSP Facet Induces an STSP Facet

The graphical traveling salesman problem (GTSP) has been studied as a variant of the classical symmetric traveling salesman problem (STSP) suited particularly for sparse graphs. In addition, it can be viewed as a relaxation of the STSP and employed for solving the latter to optimality as originally proposed by Naddef and Rinaldi. There is a close natural connection between the two associated po...

Elise Conradi to _ be _ classified A Facet

This paper examines the use of the postulational approach to facet analysis to manually induce a faceted classification ontology from a folksonomy. An in-depth study of faceted classification theory is used to form a methodology based on the postulational approach, which is then used to facet analyze a dataset consisting of over 107,000 instances of 1,275 unique tags representing 76 popular non...
