Model order reduction techniques are developed and utilized to make numerical simulations more efficient. The use of Reduce Order Models (ROM) also enables data exchange with external parties without disclosing the sensitive information present in a Full-Order Model (FOM). It is crucial to optimize for both the efficiency and accuracy of a ROM...

Fused Filament Fabrication is an additive manufacturing technique in which molten thermoplastic polymers are extruded through a nozzle. Therefore, the interplay between the viscoelastic nature of the polymer melt, temperature, printing conditions and nozzle shape may lead to inconsistent extrusion. To improve the extrusion control and...

Tracing fast nanopore-translocating analytes requires a high-frequency measurement system that warrants a temporal resolution better than 1 µs. This constraint may practically shift the challenge from increasing the sampling bandwidth to dealing with the rapidly growing noise with frequencies typically above 10 kHz, potentially making it...

In recent years, blending mechanistic knowledge with machine learning has had a major impact in digital healthcare. In this work, we introduce a computational pipeline to build certified digital replicas of cardiac electrophysiology in paediatric patients with congenital heart disease. We construct the patient-specific geometry by means of...

Radio wave treatment for pathogen suppression in glasshouse horticulture may become an alternative to steam treatment. It has several advantages, but it also requires further development before it can replace steam treatment. In a previous study we developed a numerical modeling approach to aid this development. In this present study, the...

The aerodynamic pressure load on the aircraft is vital for structural design and safety evaluation. A new method capable of identifying the pressure load on the complex surface of a three-dimensional structure is proposed. To achieve this goal, the pressure load identification technique based on subregion interpolation, which is theoretically...
