In this paper, the shape identification method in the Inverse Heat Conduction Problems (IHCP) is applied to estimate the shape of frost on a refrigeration tube. The inverse algorithm consists of direct, inverse analysis and gradient-based optimization method. The direct analysis used Finite Element Method (FEM) in an unstructured grid system to solve the direct heat conduction problem. The inverse...
Cellular location-based services need to use a variety of positioning methods to meet requirements on availability, response time, and accuracy. Due to the geometrical properties of the different positioning methods, the number of standardized reporting formats is large. Because the user requirements on the reporting formats are as scattered as the geometrical properties of the positioning methods,...
A three-dimensional wing aerodynamic design optimization procedure was developed based on the NURBS (non-uniform rational B-spline). The procedure includes NURBS-based wing geometry generation module, NURBS-based grid generation system, inviscid Euler equations solver and numerical optimization algorithm. The convex hull, local support, shape preserving forms and the variation diminishing properties...
