Hemorrhagic shock (HS) is a medical emergency during trauma. Significant loss of tissue perfusion may result in cellular hypoxia, organ damage and death. The primary treatment of HS is control of the source of bleeding as soon as possible and fluid replacement (crystalloid solutions and blood transfusion). Metabolomics can identify novel biomarkers for various functional and organic diseases. Therefore,...
In this paper, a improved inertial frame alignment algorithm is proposed, which significantly improves the accuracy and time cost of the traditional inertial frame coarse alignment algorithm. Firstly, a dimensionality reduction Gauss-Hermite filter algorithm is employed in the horizontal fine alignment phase. Secondly, according to the feature of the gravity, that the horizontal components of the...
Cooperative localization (CL) plays an important role in the application of multiple autonomous underwater vehicles (AUVs) simultaneously, by communicating with each other through acoustic modems on-board, which can not only increase the navigation performance but also reduce the navigation cost. Compared to one-way-ranging (OWR) based on precise time synchronized, the round-trip ranging (RTR) is...
A fast alignment algorithm based on inertial frame is proposed in this paper. Firstly, a third-order leveling loop is used for fine leveling alignment to establish a level coordinate frame. Secondly, the property that the projection of the gravitational vector in level coordinate frame is unrelated to heading angle is used to calculate the projection of the gravitational vector in body inertial coordinate...
