A Novel Localized Fast Multipole Method for Computations With Spatially Correlated Observation Error Statistics in Data Assimilation

Journal of Advances in Modeling Earth Systems, Volume 16, Issue 6, June 2024.
Abstract Several observation types (e.g., geostationary satellite and Doppler radar observations) have recently been found to exhibit strong spatial error correlations. Including these error statistics in data assimilation for numerical weather prediction can improve analysis quality and forecast skill.

Robust model reference tracking control for high‐order descriptor linear systems subject to parameter uncertainties

IET Control Theory &Applications, Volume 18, Issue 4, Page 479-494, March 2024.
This paper focuses on the robust model reference tracking control problem for high‐order descriptor linear systems subject to parameter uncertainties. The new robust feed‐forward compensation algorithm is proposed for high‐order descriptor linear systems, which take the first‐ or second‐order descriptor linear systems and high‐order linear systems as ...

An inverse method for structural modification of a subsystem using constrained eigenstructure assignment method to allocate single resonant frequency of whole structure

Nihon Kikai Gakkai ronbunshu
NV (Noise and vibration) performance of a mechanical system is determined by the contributions of all subsystems that make up the mechanical system. However, complex mechanical systems such as automobiles are concurrently developed, in which the supplier
