To make an accurate and real-time prediction for flight delays, referring to the thought of fuzzy membership grade, a fuzzy immune prediction method is proposed. The concepts of "self", "nonself", "antibody", "antigen" and a membership degree function for antibody to the delayed flight set are defined. During the prediction process, through real-time monitoring changes of the environment and self-adaptive adjusting λ-cut sets, the paper chooses detectors according with the current confidence level, and overcome the limitations of the deterministic model. The simulation experiment on a domestic airport shows that the method is adaptive and can accurately predict delayed flight numbers of each period all day.

In this paper we examine the effect of introducing an opportunistic cooperative navigation approach between soldiers, or first responders, equipped with foot-mounted IMUs and UWB-ranging equipment. The foot-mounted navigation system is based on a 15-state Extended Kalman filter, utilizing zero-velocity updates. The addition of range measurements between cooperative units displayed a significant improvement of the navigation accuracy in the studied scenarios. This approach has the potential to enable accurate positioning for several minutes in GPS-denied environments. Furthermore, the performance of the UWB-ranging sensor is examined and the resulting error statistics and typical ranging distances are characterized in indoor environments.
