Developing a Hybrid Data-Driven, Mechanistic Virtual Flow Meter -- a Case Study [PDF]
IFAC-PapersOnline 53 (2), 2020, 2020 Virtual flow meters, mathematical models predicting production flow rates in petroleum assets, are useful aids in production monitoring and optimization. Mechanistic models based on first-principles are most common, however, data-driven models exploiting patterns in measurements are gaining popularity.

Saccharina latissima, candy-factory waste, and digestate from full-scale biogas plant as alternative carbohydrate and nutrient sources for lactic acid production [PDF]
Bioresource Technology, Volume 380, 2023, 2023 To substitute petroleum-based materials with bio-based alternatives, microbial fermentation combined with inexpensive biomass is suggested. In this study Saccharina latissima hydrolysate, candy-factory waste, and digestate from full-scale biogas plant were explored as substrates for lactic acid production. The lactic acid bacteria Enterococcus faecium,

Identifiability and physical interpretability of hybrid, gray-box models -- a case study [PDF]
IFAC-PapersOnline 54, 2021, 2020 Model identifiability concerns the uniqueness of uncertain model parameters to be estimated from available process data and is often thought of as a prerequisite for the physical interpretability of a model. Nevertheless, model identifiability may be challenging to obtain in practice due to both stochastic and deterministic uncertainties, e.g. low data
