First, the formal representation of the search environment is established, the multi-UAV is modeled as a controlled system and the predictive model of the system is presented. Considering the uncertainty of the sensor measurement and the environment, a Search Probability Map is defined and the updating method based on Bayes formula is presented.

The presence of early CT signs has been reported to be a predictive sign of hemorrhagic complications after reperfusion therapies[4, 5, 13 18]. Our study has also demonstrated that the rate of symptomatic hemorrhagic complications showed a tendency to increase as the grade of early CT signs increased, although a statically significant difference was not proved. A grade III CT sign may be a predictive sign for hemorrhagic complications after reperfusion therapy. In contrast, the presence of a grade I CT sign may not contraindicate reperfusion therapy.
