Categorising area models for stormwater fees at propert level: A literature review
(Journal article, 2022)Worldwide, the increasing challenges due to stormwater run-off in urban areas are well known. Authorities need to be prepared for emergency situations and have plans for preventive measures to avoid flooded properties and ... -
Life Cycle Assessment under Uncertainty: A Scoping Review
(Peer reviewed; Journal article, 2022)Today, life cycle assessment (LCA) is the most widely used approach to model and calculate the environmental impacts of products and processes. The results of LCAs are often said to be deterministic, even though the real-life ... -
Cost and Emissions Reduction in CO2 Capture Plant Dependent on Heat Exchanger Type and Different Process Configurations: Optimum Temperature Approach Analysis
(Peer reviewed; Journal article, 2022)The performance of a plate heat exchanger (PHE), in comparison with the conventional shell and tube types, through a trade-off analysis of energy cost and capital cost resulting from different temperature approaches in the ... -
Evaluating the performance of advanced wells in heavy oil reservoirs under uncertainty in permeability parameters
(Peer reviewed; Journal article, 2022)Advanced wells play a crucial role in maximizing the efficiency of oil production. To achieve a successful design for advanced wells, several parameters must be considered and evaluated. Uncertainty in these parameters can ... -
A Scoping Review on Environmental, Economic, and Social Impacts of the Gasification Processes
(Peer reviewed; Journal article, 2022)In recent years, computer-based simulations have been used to enhance production processes, and sustainable industrial strategies are increasingly being considered in the manufacturing industry. In order to evaluate the ... -
The sampling interface—A critical Theory of Sampling success factor in process sampling and PAT
(Journal article, 2022)In the process industry arena, analytical endeavors are today well served by the Process Analytical Technology (PAT) framework, offering a plentitude of on-line analytics, mostly spectroscopic: UV-VIS, NIR, RAMAN, NMR, ... -
Numerical study of premixed gas explosion in a 1-m channel partly filled with 18650 cell-like cylinders with experiments
(Peer reviewed; Journal article, 2022)Abused and defective Li-ion cells can cause a catastrophic failure of a Li-ion battery (LIB), leading to severe fires and explosions. In recent years, several numerical and experimental studies have been conducted on the ... -
On Uncertainty Analysis of the Rate Controlled Production (RCP) Model
(Peer reviewed; Journal article, 2021)Rate controlled production (RCP) model is used to simulate and investigate the performance of the oil wells which are completed by autonomous inflow control devices. In order to quantify the performance of the RCP model, ... -
Intensifying rehabilitation of combined sewer systems using trenchless technology in combination with low impact development and green infrastructure
(Peer reviewed; Journal article, 2021)Throughout Europe, there is a considerable need for investment in the upgrade of sewer systems – due to three main factors: ageing infrastructure, climate change and urban population growth. The need for investments is ... -
What effect does rehabilitation of wastewater pipelines have on the share of infiltration and inflow water (I/I-water)?
(Peer reviewed; Journal article, 2021)Infiltration and inflow water (I/I-water) is a big challenge in sewage systems in many countries. I/I-water above an acceptable level indicates that the sewage system is not functioning properly. I/I-water leads to increased ... -
