We set out to implement a tool to reconstruct a 3-D triangle mesh from a set of points and the corresponding normals of an unknown surface. This surface may have arbitrarily complex topology and geometry, and may contain boundaries. We base our implementation on an influential reconstruction paper [HDD∗92]. Results were generated for a variety of challenging inputs.

This study determines the optimum insulation layer thickness to be applied external building walls considering heating degree-day (HDD) method, then energy saving costs, payback periods, and carbon dioxide (CO2) emissions are calculated accordingly. The optimisation analysis is performed for four different thermal materials (glass wool, rock extruded polystyrene, expanded polystyrene). Natural ...

Permutation codes are error-correcting over symmetric groups. We focus on permutation under Chebyshev (ℓ∞) distance. A code invented by Kløve et al. is of length n, size 2n-d and, minimum distance d. denote the φn,d. This largest known n and d > n/2 so far, to best authors knowledge. They also devised efficient encoding hard-decision decoding (HDD) algorithms that outperform bounded decoding. I...

The Synthetic Vision Systems General Aviation (SVS-GA) element of NASA's Aviation Safety Program is developing technology to eliminate low visibility induced General Aviation (GA) accidents through the application of synthetic vision techniques. SVS displays present computer generated 3-dimensional imagery of the surrounding terrain to greatly enhance pilot's situation awareness (SA), reducing ...

Digital audio broadcasting (DAB) systems for the AM band are being developed to provide higher-quality radio broadcasts, broader coverage, and data services. Transmission is typically done by means of multistreaming with QAM/OFDM in the high bits/sec/Hz regime, in which Reed–Solomon codes, either alone or in concatenation with inner trellis coded modulation (TCM), are natural choices for error ...
