We propose a robust and effective mesh denoising approach consisting of three steps: vertex pre-filtering, L1-median normal filtering, and vertex updating. Given an input noisy mesh model, our method generates a high quality model that preserves geometric features. Our approach is more robust than state of the art approaches when denoising models with different levels of noise and can handle mo...

The Hasselblad H3D digital camera, which is designed for professional studio shootings, is equipped with a 39 megapixel digital back. It would be desirable to use this very high geometric resolution in photogrammetric applications. Unfortunately, the digital back does not have a tight connection to the camera body. In addition, the unknown internal image processing algorithms and the autofocus ...

Packing Three-Dimensional Irregular Objects Because of its many applications in practice, the cutting and packing literature is extensive well established. It mostly concerned with problems one two dimensions or where some regularity pieces assumed (e.g., boxes). However, rise realm three-dimensional printing additive manufacturing has created a demand for efficient irregular objects. In “Voxel...

Gk (geometrically continuous surface) constructions were developed to create surfaces that are smooth also at irregular points where, in a quad-mesh, three or more than four elements come together. Isogeometric elements were developed to unify the representation of geometry and of engineering analysis. We show how matched Gk constructions for geometry and analysis automatically yield Ck isogeom...

In this paper we present a new diagonal balancing technique for regular matrix pencils λB − A, which aims at reducing the sensitivity of the corresponding generalized eigenvalues. It is inspired from the balancing technique of a square matrix A and has a comparable complexity. Upon convergence, the diagonally scaled pencil has row and column norms that are balanced in a precise sense. We also s...

In the whole aircraft structural optimization loop, thermal analysis plays a very important role. But it faces severe computational burden when directly applying traditional numerical tools, especially each involves repetitive parameter modification and analysis. Recently, with fast development of deep learning, several Convolutional Neural Network (CNN) surrogate models have been introduced to...

Reduction in the moisture content of the medium produced a profound effect on the colony morphology of Campylobacter fetus subsp. jejuni. Fresh medium produced flat, grayfish, spreading colonies with an irregular shape and variety appearance. Plates that were incubated at 30 degrees C for 48 h produced round, convex, butyrous colonies with an entire edge. Plates incubated at 30 degrees C for 24...
