Interconnects play a critical role in various networking environments including data center networks, high performance computing systems, networks-on-chip, etc. An important design concern of interconnects is the hardware cost, especially when the scale increases. In order to achieve lower hardware cost, a lot of previous work leverages a tradeoff between the cost and the performance. In this paper,...
Recently, geometric routing has emerged as an efficient routing strategy on wireless networks. An ideal geometric routing is memoryless and does not suffer from the drawbacks of traditional proactive/reactive routings. All existing geometric routings on 3-D wireless networks either work deterministically only on the networks with special properties or do not guarantee delivery. In this paper, we divide...
Fast and accurate segmentation for color images are important and difficult in computer vision and image analysis. To improve the quality of image recognition, take into account pixel color information and adjacency relationship between pixels based on spatial information, integrate color histogram-based method and region growing and merging-based segmentation method, proposed a new algorithm for...
Numerous algorithms on geometric networks has been studied, and most of them were based on 2-dimensional networks. But 2-dimensional geometric routing algorithms cannot be directly adapted to the 3-dimensional networks. In this paper, we propose routing algorithms based on the iteration of specific angles on the networks of Delaunay Triangulation in 3D space, and prove the certainty of data transmission...
Focusing on nonlinear/non-Gaussian filters and based on analysis of the sampling-importance-resampling algorithm, this paper examines principles and application of particle filter (PF) in satellite orbit determination. There may be large error of initial estimation and non-Gaussian distribution of state and measurement in satellite orbit determination. To solve the two problems, an improved PF algorithm...
