Terrain database is the reference basic for autonomous underwater vehicle (AUV) to implement underwater terrain navigation (UTN) functions, and is the important part of building topographical features model for UTN. To investigate the feasibility and correlation of a variety of terrain parameters as terrain navigation information metrics, this paper described and analyzed the underwater terrain features...
Neuromorphic vision algorithms are biologically inspired algorithms that follow the processing that takes place in the visual cortex. These algorithms have proved to match classical computer vision algorithms in classification performance and even outperformed them in some instances. However, neuromorphic algorithms suffer from high complexity leading to poor execution times when running on general...
Guanxi is a type of dyadic social interaction based on feelings, trust, and the development of friendship. In this paper, we define the concept of guanxi as it is applied to the interaction between web sites. We show by analyzing the local linking structure between Chinese web sites and the content of Chinese web documents that interaction between Chinese web sites can be seen to exhibit two types...
Compared with other metal fluorides, the rare earth trifluorides (mainly refers to the trifluorides of light rare earths such as La, Ce, Gd, etc.) are more thermally and chemically stable. Therefore, some rare earth trifluorides have been used as high temperature solid lubricants. For example, LaF 3 and CeF 3 have been applied in lubricating greases and bonded films recently. But the...
