Protosolid: An inside look

Performance Analysis of a Polyhedral Boolean Set Operations Algorithm

In performing regularized set. operations on two solids, the most difficult step is boundary classification, in which the boundaries of each solid are split into portions that are inside, outside, or on the surface of the other solid. In this paper, we present a method for doing boundary classification on polyhedral solids and give measurements of the algorithm's time complexity on a number of ...

Inverses of Motzkin and Schröder Paths

We suggest three applications for the inverses: For the inverse Motzkin matrix we look at Hankel determinants, and counting the paths inside a horizontal band, and for the inverse Schröder matrix we look at the paths inside the same band, but ending on the top side of the band.

A Look inside the ITC-irst SMT System

This paper presents a look inside the ITC-irst largevocabulary SMT system developed for the NIST 2005 Chinese-to-English evaluation campaign. Experiments on official NIST test sets provide a thorough overview of the performance of the system, supplying information on how single components contribute to the global performance. The presented system exhibits performance comparable to that of the b...

A piece of steel may look cold and lifeless. But like any other piece of matter, it is bursting with activity deep inside. Electrons whiz around inside atoms, and a sea of never-resting quarks and gluons populates the nucleons

How you feel on the inside could be affecting how you look on the outside.
