Dependable visual light-based indoor localization with automatic anomaly detection for location-based service of mobile cyber-physical systems
Liu Y., Chen X., Kadambi D., Bari A., Li X., Hu S., Zhou P. ACM Transactions on Cyber-Physical Systems 3(1): 1-17, 2018. Type: Article
Indoor localization for mobile devices can employ beacons inserted in known positions in the environment. Light-emitting diodes (LEDs) are becoming popular beacons because of their simplicity; however, using the light for localization presents pro...

Algebraic conditions for classifying the positional relationships between two conics and their applications
Liu Y., Chen F. Journal of Computer Science and Technology 19(5): 665-673, 2004. Type: Article
Following the ideas of Wang et al. , this paper presents several techniques from computer algebra (mainly resultants) to characterize the relative position between two conics. This relative position is described in terms of the roots and factor...
