Variational Bayesian-Based Maximum Correntropy Cubature Kalman Filter Method for State-of-Charge Estimation of Li-Ion Battery Cells

IEEE Transactions on Vehicular Technology, 2023
State-of-charge estimation is an essential part of a battery management system. Charging and discharging batteries involve complex chemical processes that could lead to undesired consequences, such as premature end of life or fire hazards if the battery ...

Robust adaptive cubature Kalman filter for tracking manoeuvring target by wireless sensor network under noisy environment

IET Radar, Sonar & Navigation, 2023
The existing adaptive Kalman filters for tracking manoeuvring targets by wireless sensor networks can easily lose robustness when both the measurement and process noises are unknown and time‐varying, resulting in large positioning errors.

Monte Carlo cubature construction [PDF]

Japan Journal of Industrial and Applied Mathematics, 2020
AbstractIn numerical integration, cubature methods are effective, especially when the integrands can be well-approximated by known test functions, such as polynomials. However, the construction of cubature formulas has not generally been known, and existing examples only represent the particular domains of integrands, such as hypercubes and spheres. In

Efficient cubature rules [PDF]

ETNA - Electronic Transactions on Numerical Analysis, 2019
73 new cubature rules are found for three standard multidimensional integrals with spherically symmetric regions and weights, using direct search with a numerical zero-finder. All but four of the new rules have fewer integration points than known rules of the same degree, and twenty are within three points of M{ö}ller's lower bound.

Representations of Multi-Attribute Grain Quality

Journal of Agricultural and Resource Economics, 2001
Grain quality is typically measured via several attributes. As these attributes vary across shipments and time, grain quality can be described using multivariate probability or frequency distributions.

Fast cubature of volume potentials over rectangular domains [PDF]

, 2013
In the present paper we study high-order cubature formulas for the computation of advection-diffusion potentials over boxes. By using the basis functions introduced in the theory of approximate approximations, the cubature of a potential is reduced to ...
