Error Distinguish of Ais Based on Evidence Combination
نویسنده
چکیده
The Automatic Identification System (AIS) is essential digital communication equipment for maritime safety in inland rivers. The occasional error of GNSS (Global Navigation Satellite System) devices in the AIS equipment will make the terminal send fake dynamic information discontinuously, which needs to be distinguished manually. With the help of the DSmT method, gathering and qualifying the ships motion and lane characteristics, making mathematical models of Dθ discernment frame, it is possible to develop the artificial intelligence. And it is able to discriminate the abnormal messages to improve the reliability of AIS data link. The method has been proved feasible and effective in both simulation environment and field data processing.

The sailing tracks of single otter trawl vessels were simulated using cubic hermite spline (cHs) interpolation method based on the automatic identification system (AIS) data of 6 sampled vessels that were fishing in the Zhoushan fishing grounds after the close of the fishing season from September 2012 to January 2013. The vessels’ status (i.e. whether the vessels were fishing or not) were dete...

Artificial immune system (AIS) is one of the most meta-heuristic algorithms to solve complex problems. With a large number of data, creating a rapid decision and stable results are the most challenging tasks due to the rapid variation in real world. Clustering technique is a possible solution for overcoming these problems. The goal of clustering analysis is to group similar objects. AIS algor...

Evidence-based management and development planning relies on official statistics. There are some obstacles that make it impossible to do single mode survey. These obstacles are sampling frame, time, the budget and accuracy of measurment of each mode. Always we can not use single mode survey becase of these factors. So we need to use other data collection method to overcome these obstacles. T...
متن کاملLong-Term Effects of Untreated Adolescent Idiopathic Scoliosis: A Review of the Literature
Currently, adolescent idiopathic scoliosis (AIS) is principally regarded as benign, but some researchers have cited serious or extreme effects, including severe pain, cardiopulmonary compromise, social isolation, and even early death. Therefore, exploration of the long-term effects of AIS, the most common type of idiopathic scoliosis, is warranted. The purpose of this review was to examine the ...
