The wireless meshed technology is one of the most advanced technology and can be viewed as the technology of the future. This article deals with aspects like performance metrics i.e. delay, R-Factor and Mean Opinion Score (MOS) that have a direct influence on the performance of the wireless mesh network. In this paper voice quality is analyzed in terms of R-Factor and MOS in Wireless Mesh Netwo...

In Robotics, especially in this era of autonomous driving, mapping is one key ability of a robot to be able to navigate through an environment, localize on it and analyze its traversability. To allow for real-time execution on constrained hardware, the map usually estimated by feature-based or semidense SLAM algorithms is a sparse point cloud; a richer and more complete representation of the en...

We present the theory and implementation for a new automatic adaptive h-re nement and -dere nement method for twoand three-dimensional elliptic problems. An exact lower error bound for dere nement is obtained theoretically in terms of the nite element solution, complementing the various known upper error bounds for re nement. These error bounds are used to determine where to insert and/or remov...

New techniques for numerically solving systems of first-order ordinary differential equations are obtained by finding local Galerkin approximations on each subinterval of a given mesh. Different classes of methods correspond to different quadrature rules used to evaluate the innerproducts involved. At each step, a polynomial of degree/; is constructed and the arcs are joined together continuous...

Subdivision schemes are commonly used to obtain dense or smooth data representations from sparse discrete data. E. g., B-splines are smooth curves or surfaces that can be constructed by infinite subdivision of a polyline or polygon mesh of control points. New vertices are computed by linear combinations of the initial control points. We present a new non-linear subdivision scheme for the refine...

We present a novel surface reconstruction approach for generating surfaces from animated particle data, targeting temporally coherent surface reconstruction that can also approximate smooth surfaces and capture fine details. Our beta mesh algorithm uses the union of balls as a building block to reach temporal coherence. First we construct mesh vertices from sphere intersection points, and decla...

Preparing a facial mesh to be animated requires a laborious manual rigging process. The rig specifies how the input animation data deforms the surface and allows artists to manipulate a character. We present a method that automatically rigs a facial mesh based on Radial Basis Functions (RBF) and linear blend skinning approach. Our approach transfers the skinning parameters (feature points and t...

In this paper we present an algorithm of simple implementation but very effective that guarantees to keep an optimal stripification (in term of frames per seconds) over a progressive mesh. The algorithm builds on-the-fly the stripification on a mesh at a selected level-of-details (LOD) using the stripifications built, during a pre-processing stage, at the lowest and highest LODs. To reach this ...

a fundamental topic in computational fluid dynamics is the role of coordinate particularly for searching optimized coordinates. the objective of this study is the numerical modeling of supersonic flows using a new coordinate system i.e. unified coordinate system (ucs) uses moving mesh with motionless viewing window technique. ucs has an advantage over traditional coordinate systems (eulerian an...
