Cerebrospinal fluid dynamics coupled to the global circulation in holistic setting: Mathematical models, numerical methods and applications. [PDF]

Int J Numer Method Biomed Eng, 2022
This paper presents a mathematical model of the global, arterio‐venous circulation in the entire human body, coupled to a refined description of the cerebrospinal fluid dynamics in the craniospinal cavity. The improvements concern physiological aspects, underlying mathematical models as well the associated computational methods. A major novelty of this

Vibration control for the solar panels of spacecraft: Innovation methods and potential approaches

International Journal of Mechanical System Dynamics, Volume 3, Issue 4, Page 300-330, December 2023., 2023
Abstract Solar panels on spacecraft are typical kinds of flexible structures. Low‐frequency and large‐amplitude vibrations usually occur due to the inevitable disturbances of deployment impact, attitude/orbit maneuver, separation/docking impact, and so forth.

Direction finding by sparse‐based approach for dual‐polarised conformal array in the presence of gain and phase uncertainties

IET Radar, Sonar &Navigation, Volume 17, Issue 6, Page 1040-1049, June 2023., 2023
We investigate the problem of robust direction‐of‐arrival (DOA) estimation with unknown antenna gain and phase uncertainties for the dual‐polarised conformal array. Some techniques including weight sharing, grid pruning, and suppressing the equivalent noise have been adopted to significantly alleviate the negative effects of uncertainties and enhance ...

Feedback stabilization of switched linear systems via a parametric approach

IET Control Theory &Applications, Volume 17, Issue 6, Page 683-695, April 2023., 2023
Two multiple matrix equation problems completely solved in parametric forms. Feedback stabilizaiton for certain linear switched systems under arbitrary switching is realized. Abstract This paper solves two matrix equations problems completely which are originated from the problems of state feedback stabilization of first‐order and second‐order switched

Construction of hybrid 1D‐0D networks for efficient and accurate blood flow simulations

International Journal for Numerical Methods in Fluids, Volume 95, Issue 2, Page 262-312, February 2023., 2023
A set of coupling equations to appropriately couple nonlinear 1D and lumped‐parameter (0D) models for blood flow in compliant vessels is defined. Then, a methodology for the high‐order numerical coupling between 1D and 0D vessels through hybrid junctions is proposed.

A flux‐vector splitting scheme for the shallow water equations extended to high‐order on unstructured meshes

International Journal for Numerical Methods in Fluids, Volume 94, Issue 10, Page 1679-1705, October 2022., 2022
We present an advection‐pressure flux‐vector splitting method for the one and two‐dimensional shallow water equations. The resulting first‐order schemes turn out to be exceedingly simple, with accuracy and robustness comparable to that of the sophisticated Godunov upwind methods.

[Retracted] Sport Resource Classification Algorithm for Health Promotion Based on Cloud Computing: Rhythmic Gymnastics’ Example

Journal of Environmental and Public Health, Volume 2022, Issue 1, 2022., 2022
In the processing of rhythmic gymnastics resources, there are inefficiency problems such as confusion of teaching resources and lack of individuation. To improve the health access to teaching resource data, such as videos and documents, this study proposes a cloud computing‐based personalized rhythmic gymnastics teaching resource classification ...
