Digital Terrain Modeling, the Triangulated Irregular Network (TIN) is a representation of a surface derived from irregularly spaced sample points and break line features. Paper deals with the basic concept of Delauney’s triangulation method with its practical approach in ArcGIS. The next section describes the process to convert mass points to TIN model and explores some of the basics of TIN Mod...

Confronted with the high-dimensional tensor-like visual data, we derive a method for the decomposition of an observed tensor into a low-dimensional structure plus unbounded but sparse irregular patterns. The optimal rank-(R1, R2, ...Rn) tensor decomposition model that we propose in this paper, could automatically explore the low-dimensional structure of the tensor data, seeking optimal dimensio...

This paper addresses the synthesis of near-regular textures, i.e. textures that consist of a regular global structure plus subtle yet very characteristic stochastic irregularities. Such textures are difficult to synthesize due to the complementary characteristics of these structures. In this paper, we propose a method which we call Random Sampling and Gap Filling (RSGF) to synthesize near-regul...

Finding a match between partially available deformable shapes is a challenging problem with numerous applications. The problem is usually approached by computing local descriptors on a pair of shapes and then establishing a point-wise correspondence between the two. In this paper, we introduce an alternative correspondence-less approach to matching fragments to an entire shape undergoing a non-...

A standard way of dealing with matrix polynomial eigenvalue problems is to use linearizations. Byers, Mehrmann and Xu have recently defined and studied linearizations of dimensions smaller than the classical ones. In this paper, lower bounds are provided for the dimensions of linearizations and strong linearizations of a given m×n matrix polynomial, and particular linearizations are constructed...

The nite-element, semi-implicit, and semi-Lagrangian methods are combined together to solve the shallow-water equations using unstructured triangular meshes. Triangular nite elements are attractive for ocean modeling because of their exibility for representing irregular boundaries and for local mesh re nement. A \kriging" interpolator is used for the semi-Lagrangian advection, leading to an acc...

The most conspicuous structural characteristic of the alpha-helical membrane proteins is their long transmembrane alpha-helices. However, other structural elements, as yet largely ignored in statistical studies of membrane protein structure, are found in those parts of the protein that are located in the membrane-water interface region. Here, we show that this region is enriched in irregular st...

At present, typical application-specific NoC systems often integrate a number of heterogeneous components which have varied functions, sizes and communication requirements. Instead of regular topology networks, constructing irregular mesh topology network on chip (NoCs) becomes an attractive approach to building future NoC systems with irregular structure. Deadlock-free routing control algorith...

Pause is not only one of the cues of prosodic structure for running speech, but also one of the strategies used by speakers to express their emotions. In this paper, we investigated the silent pauses in read and spontaneous speech, neutral and expressive speech, as well as synthesized speech, trying to find the difference of silent pause patterns in different speech styles. It was observed that...

Standard spatial convolutions assume input data with a regular neighborhood structure. Existing methods typically generalize convolution to the irregular point cloud domain by fixing “view” through e.g. fixed size, where kernel size remains same for each point. However, since clouds are not as structured images, neighbor number gives an unfortunate inductive bias. We present novel graph named D...
