Paper Number: SNAME-CSYS-2022-014
... vector zk. But in practice when performing sensor fusion, measurements are hardly ever received simultaneously nor with the same frequency. Each sensor has its measurement frequency and sensors are usually not synchronized. If the measurements frequencies are multiples of a common frequency, we can...

... coefficients of the NACRA 17 hydrofoils are determined based on unsteady Computational Fluid Dynamics (CFD) simulations with a free surface. In the simulations the foil is moved in prescribed motions in one degree of freedom (DOF) at a time and dynamic coefficients are extracted for different frequencies...

... structures to reduce the loads by reducing the incidence at the tip. (Gozcu et al., 2015Rohde et al., 2015) investigated the effect of this coupling on natural frequencies and mode shape to improve the design and the control of composite structures. The present study investigates the impact of composite...
