Introduction Accurate placement of pedicle screws in spine surgery is a challenge for surgeons. Patient-specific template techniques have the potential for improving the accuracy of screw placement. The target of this analysis was to investigate differences in terms of accuracy of pedicle screw insertion between patient-specific template assistance and the conventional free-hand method for reconstruction...
Considering the fact that each wireless senor node owns limited power in wireless sensor networks, a new type of distributed Kalman-consensus filtering algorithm based on event-driven is proposed for reducing energy consumption. This event-driven scheme is triggered by the updated covariance which is commonly used to describe errors between the true value and the estimated one. In this scheme, each...
Target identification has been an active researching area in past decades. In this paper, we present an iteration procedure to optimize the size of the undercomplete dictionary when multiple undercomplete dictionaries are used to characterize the scattering signatures of a complex target. Furthermore, we extend the signature reconstruction and decision criterion with only single undercomplete dictionary...
