where CP is the cavity of P and BP the ball of P . We derive two algorithms to compute Cp. The first algorithm is tuned to be a fast point reprojection to the geometry even in the presence of a boundary layer mesh. The second one is tuned to generate boundary layer meshes for complex geometries. We show how quasistructured elements can be enforced. In addition, enhancements as multi-normals can...

This paper addresses the interference and load imbalance problems in multi-radio infrastructure mesh networks where each mesh node is equipped with multiple radio interfaces and a subset of nodes serve as Internet gateways. To provide backbone support, it is necessary to reduce interference and balance load in Wireless Mesh Networks (WMNs). In this paper, we propose a new Load-Aware Routing Met...

A fast iterative method for constructing a smooth subdivision surface that interpolates the vertices of an arbitrary mesh is presented. The construction is done by iteratively adjusting vertices of the given mesh locally until control mesh of the required interpolating surface is reached. The new interpolation method has not only the simplicity of a local method, but also the capability of a gl...

This paper presents a high-capacity data hiding method for 3D polygonal meshes. By slightly modifying the distance from a vertex to its traversed neighbors based on quantization, a watermark (i.e., a string of binary numbers) can be embedded into a polygonal mesh during a mesh traversal process. The impact of embedding can be tuned by appropriately choosing the quantization step. The embedded d...

The CSMA/CA based random channel access mechanisms in Wireless Mesh Networks(WMNs), IEEE 802.11 DCF and EDCA, are inefficient to eliminate effectively hidden terminal and exposed terminal problems in multi-hop scenarios. In this paper, we propose efficient channel assignment and routing protocols for multi-radio multi-channel (MRMC) wireless mesh networks. These set of protocols are based on La...

The numerical solution of one-dimensional phase change problems using an adaptive moving mesh method. An adaptive moving mesh method is developed for the numerical solution of an enthalpy formulation of heat conduction problems with a phase change. The algorithm is based on a very simple mesh modiication strategy that allows the smooth evolution of mesh nodes to track interfaces. At each time s...

As the scarce spectrum resource is becoming over-crowded, cognitive radios (CRs) indicate great flexibility to improve the spectrum efficiency by opportunistically accessing the authorized frequency bands. One of the critical challenges for operating such radios in a network is how to efficiently allocate transmission powers and frequency resource among the secondary users (SUs) while satisfyin...
