This review paper focuses on modelling of wastewater treatment plants (WWTP). White-box modelling is widely applied in this field, with learning, design and process optimisation as the main applications. The introduction of the ASM model family by the IWA task group was of great importance, providing researchers and practitioners with a standardised set of(More)
—Distributed energy resources (DERs), like electric vehicles (EVs), can offer valuable services to power systems, such as enabling renewable energy to the electricity producer and providing ancillary services to the system operator. However, these new DERs may challenge the distribution grid due to insufficient capacity in peak hours. This paper aims to(More)
The paper provides an overview of Multilevel Flow Modeling (MFM) and its application for design of displays for supervisory control of industrial plant. The problem of designing the information content of supervisory displays is discussed and plant representations like MFM using levels of means-end and part-whole abstractions are proposed as a solution to(More)
In a recent population-based case–control study using 2,400 cases of childhood cancer, we found a statistically significant association between residential radon and acute lymphoblastic leukemia risk. Traffic exhaust in the air enhances the risk association between radon and childhood leukemia. We included 985 cases of childhood leukemia and 1,969 control(More)
A linear regression model has been developed for the prediction of indoor (222)Rn in Danish houses. The model provides proxy radon concentrations for about 21,000 houses in a Danish case-control study on the possible association between residential radon and childhood cancer (primarily leukaemia). The model was calibrated against radon measurements in 3116(More)
The paper discusses the abstraction hierarchy proposed by Rasmussen [(1986) Information processing and human-machine interaction, North-Holland] for design of human-machine interfaces for supervisory control. The purpose of the abstraction hierarchy is to represent a work domain by multiple levels of means-end and part-whole abstractions. It is argued in(More)
OBJECTIVE To assess the effect of bilateral ultrasound-guided transversus abdominis plane block with ropivacaine compared with placebo as part of a multimodal analgesic regimen. DESIGN A randomized, double-blind, placebo-controlled trial following the CONSORT criteria. SETTING Hvidovre University Hospital. PATIENTS Forty-six women scheduled for total(More)
