PACS. 05.45.-a – Nonlinear dynamics and nonlinear dynamical systems. Abstract. – The Internet is a worldwide communication network, whose optimization depends on the knowledge of the statistical characterization of the aggregated traffic flow. Inter-net traffic is dependent on a number of factors, including communication protocols, network topology, and(More)
A moving mesh method for semiconductor device simulation is developed which effectively compromises accuracies without increasing mesh number. In this method, mesh positions are shifted referring to the solution of the previous bias condition, or to the Newton corrections. The method is applied to solve PN-junctions and MOSFETs. The method provides an(More)
One promising method for coding 3-D geometry data is based on the structure processing of a 3-D model on triangle lattice planes, while maintaining connectivity. In the structuring process, each vertex may be assigned to several nodes on the triangular lattice planes. One of the nodes to which a vertex is assigned is selected as a representative node and(More)
This paper presents a new coding method for 3-D geometry data using surface simplification and the wavelet transform. A polygonal mesh model is constructed from the connectivity information and the geometric data. We have previously presented a coding method for the structured geometry data structured on a 2-D lattice plane. In this paper we present a(More)
