Sensors, Vol. 14, Pages 21281-21315: Online Variational Bayesian Filtering-Based Mobile Target Tracking in Wireless Sensor Networks

11-11-2014 | Zhou, Bingpeng ; Chen, Qingchun ; Li, Tiffany Jing; Xiao, Pei, Sensors, 2014

The received signal strength (RSS)-based online tracking for a mobile node in wireless sensor networks (WSNs) is investigated in this paper. Firstly, a multi-layer dynamic Bayesian network (MDBN) is introduced to characterize the target mobility with either directional or undirected movement. In ...

Entropy, Vol. 16, Pages 5822-5837: Plant Friendly Input Design for Parameter Estimation in an Inertial System with Respect to D-Efficiency Constraints

06-11-2014 | Jakowluk, Wiktor, Entropy, 2014

System identification, in practice, is carried out by perturbing processes or plants under operation. That is why in many industrial applications a plant-friendly input signal would be preferred for system identification. The goal of the study is to design the optimal input signal which is then ...
