SPECSweb multistatic tracking on a truth-blind Simulated Scenario of the MSTWG
2009 12th International Conference on Information Fusion, 2009Co-Authors: Doug GrimmettAbstract:Effective fusion and tracking of multistatic active sonar contacts is challenging, due to high levels of false alarm clutter present on all sonar nodes. Such false alarms often overload the sensor-to-fusion-center communications links and fusion/tracking processes, producing too many false tracks. The specular-cued surveillance Web (SPECSweb) multistatic tracker mitigates these problems through implementation of two amplitude thresholds: a high threshold used to identify the occurrence of high-strength specular detection cues for track initiation, and a low threshold for selective extraction of additional detections within retrieval snippets for track extension forward and backward in time. This approach can significantly reduce the data rate at the input to the fusion/tracking algorithm, and reduce node-to-fusion-center communication link throughput requirements. This paper provides performance results of this tracking algorithm on Simulated multistatic data sets from the multistatic tracking working group (MSTWG). These included a (ldquotruth-blindrdquo) data set for which the target truth information was not provided in advance of the time of algorithm application. The results show effective tracking performance using this approach, yielding high quality target tracks with no or few false tracks. The method is shown to have excellent potential in reducing the overloading of the communication links, the automated tracking algorithm, and the ultimately, the operator.

FUSION - MSTWG multistatic tracker evaluation using Simulated Scenario data sets
2008Co-Authors: Doug Grimmett, Stefano Coraluppi, Brian R. La Cour, Christian G. Hempel, Thomas Lang, Pascal A.m. De Theije, Peter WillettAbstract:The multistatic tracking working group (MSTWG) was formed in 2005 by an international group of researchers interested in developing and improving tracking capabilities when applied to multistatic sonar and radar problems. The MSTWG developed several Simulated multistatic sonar Scenario data sets for use in tracker evaluation by the grouppsilas participants. A common set of performance metrics was also agreed, to enable tracker algorithm comparison and evaluation. Previous conference special sessions of the MSTWG have reported individual algorithm performance on these data sets. In this paper, the various results are consolidated in order to make a first attempt at performance cross-comparisons. The data sets are reviewed and performance results are presented. Issues with various performance metrics are explained.

ICIA - Real-time dynamic addressing for spacecraft soft landing in the lunar surface
2015 IEEE International Conference on Information and Automation, 2015Co-Authors: Liang He, Yujian Feng, Jianhua Zhang, Shengyong ChenAbstract:During the process of the soft landing, because of the lunar surface topography, the spacecraft will be subject to the threat of an obstacle and makes the landing fail. Therefore, hazard avoidance and addressing are the key technology for spacecraft soft landing in the lunar surface. In this paper, algorithms are described for vision-based hazard detection, safe site selection and real-time dynamic addressing. The algorithms are validated in a realistic Simulated Scenario representing a landing on lunar. Results show that the developed hazard avoidance algorithms are effective at detecting hazards and guiding the lander to a safe landing site.

Undergraduates performance on vaccine administration in Simulated Scenario.
Revista Brasileira De Enfermagem, 2019Co-Authors: Lívia Cristina Scalon Da Costa, Carolina Costa Valcanti Avelino, Lara Aparecida De Freitas, Aline Aparecida Machado Agostinho, Maria Betânia Tinti De Andrade, Sueli Leiko Takamatsu GoyatáAbstract:OBJECTIVE: To evaluate the performance of nursing undergraduates on administration of vaccines in the vastus lateralis muscle of the thigh in children as a proposal of intervention, using Simulated Scenario, skill training and virtual learning environment. METHOD: Quantitative, quasi-experimental, pre and post-test, performed with 39 nursing students from a federal public university in 2017. The cognitive knowledge test and the Objective Structured Clinical Examination (OSCE) checklist were prepared, validated and applied before and after the intervention, adopting a level of significance of 95%. RESULTS: The mean of the pre-test scores was 12.5 (SD= 2.56), post-test 17.4 (SD= 2.38), p
