Data-driven reduced-order modelling for blood flow simulations with geometry-informed snapshots
Dongwei Ye, Valeria Krzhizhanovskaya, Alfons G. Hoekstra
Parametric reduced-order modelling often serves as a surrogate method for hemodynamics simulations to improve the computational efficiency in many-query scenarios or to perform rea…
Inverse uncertainty quantification of a mechanical model of arterial tissue with surrogate modeling
Salome Kakhaia, Pavel Zun, Dongwei Ye +1
Disorders of coronary arteries lead to severe health problems such as atherosclerosis, angina, heart attack and even death. Considering the clinical significance of coronary arteri…
Modelling Hospital Strategies in City-Scale Ambulance Dispatching
Xinyu Fu, Valeria Krzhizhanovskaya, Alexey Yakovlev +1
The optimisation in the ambulance dispatching process is significant for patients who need early treatments. However, the problem of dynamic ambulance redeployment for destination…
