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

Forecasting the production of Distillate Fuel Oil Refinery and Propane Blender net production by using Time Series Algorithms [PDF]
arXiv, 2022 Oil production forecasting is an important step in controlling the cost-effect and monitoring the functioning of petroleum reservoirs. As a result, oil production forecasting makes it easier for reservoir engineers to develop feasible projects, which helps to avoid risky investments and achieve long-term growth.

Influence of petroleum and gas trade on EU economies from the reduced Google matrix analysis of UN COMTRADE data [PDF]
Eur. Phys. J. B (2019) 92: 171, 2019 Using the United Nations COMTRADE database we apply the reduced Google matrix (REGOMAX) algorithm to analyze the multiproduct world trade in years 2004-2016. Our approach allows to determine the trade balance sensitivity of a group of countries to a specific product price increase from a specific exporting country taking into account all direct and ...
