In order to finish the phase unwrapping of multi-baseline InSAR (Interferometric Synthetic Aperture Radar) to combine data with longer and shorter baselines and derive accurate DEMs (Digital Elevation Models), a phase unwrapping model with linear congruent equations is designed and its solution with the Chinese Remainder Theorem (CRT) is presented in detail. In this algorithm, the un-fuzzy phase interval...
We call a finite graph G = (V,E) a binary network if the state set of its nodes has only two elements, say, 0 and 1, representing respectively ‘OFF’ and ‘ON’ state. A switch at node v switches both the state of v and the state of each of its neighbors. It is shown in [1] that given any initial state of a network of order n > 3, we can always reach at a consistent status, i.e., either all the nodes...
Complex scenes and radiance distributions are common in realistic image synthesis. The variance of Monte Carlo sampling is large in these situations. Therefore adaptive method is needed to sample efficiently. We present an object space adaptive sampling method to handle complex radiance distributions in global illumination. The scene is segmented into sub-regions with a 5D tree, and the incident radiance...
This paper presents to evaluate the vibration and sound radiation of a finite functionally graded material cylindrical shell immersed in light and heavy fluid and excited by a constant point load continuously traveling along the circumferential direction at a rotational speed . Attention is focused on the explanation of radiation phenomena in both fluids and the FGM shell's parameter influence of...
