River Flow Prediction by Multiplicative Kalman Filter

Multiplicative Extended Kalman Filter for Relative Rotorcraft Navigation

In this article we detail the fundamentals of a new approach to GPS-denied navigation for aerial vehicles in confined indoor environments. We depart from the common practice of navigating within a globally referenced map, and instead keep the position and yaw states relative to the current node in the map. The approach combines elements of graph SLAM with a multiplicative extended Kalman filter...

Influenza Trend Prediction Using Kalman Filter and Particle Filter

Background. Seasonal influenza can cause severe health problems and significant economic burdens in various regions of the world. In addition to the substantial morbidity and mortality cases caused by influenza, the emergency department crowding is also partially attributed to the influenza patients. Forecasting the influenza trends is crucial in developing effective countermeasures to mitigate...

Estimation of River Current Using Kalman Filter Finite Element Method

This paper presents an estimation technique using the Kalman filter finite element method ( KF-FEM ). Estimation value that is not observed is estimated by KF-FEM, which is the combination method of the Kalman filter and the finite element method. The Kalman filter is employed for the solution of time series analysis and the finite element method is for space analysis. In this paper the shallow...
