Wastewater infrastructure has a long lifetime and is subject to changing conditions and demands. When plans are made to upgrade or build new infrastructure, transdisciplinary planning processes and a robust analysis of future conditions are needed to make sustainable choices. Here, we provide a stepwise collaborative planning process in which future scenarios are developed together with local stak
This paper presents a systematic approach to robust preconditioning for gradient-based nonlinear inverse scattering algorithms. In particular, one- and two-dimensional inverse problems are considered where the permittivity and conductivity profiles are unknown and the input data consist of the scattered field over a certain bandwidth. A time-domain least-squares formulation is employed and the inv
OBJECTIVE: : The aim of this study is to determine Swedish parents' willingness to pay (WTP) for coeliac disease (CD) screening of their child. SUBJECTS AND METHODS: : CD screening was undertaken involving 10,041 12-year-old children, with 7567 (75%) agreeing to participate. Blood samples from the children were analysed for CD serological markers. Parents received a questionnaire including a scen
Freight transport in urban areas needs to become more sustainable. There is much potential to reduce emissions by transitioning to electric freight vehicles (EFVs). The context of this study is Sweden, a country with ambitious goals for transitioning to fossil-free road transport that incentivizes the adoption of EFVs through regulations, subsidies and environmental zones. However, it seems that f
Cities have been wildly successful over recent years in positioning themselves at the center of the global conversation on climate change. For example, the Intergovernmental Panel on Climate Change (IPCC) recently convened the Cities & Climate Change Conference (CitiesIPCC) in Edmonton, Alberta. The conference — hosted by a city that once advertised itself as Canada’s oil capital — brought tog
Classical molecular dynamics simulations are a common component of multi-modal analyses of scattering measurements, such as small-angle scattering and diffraction. Users of these experimental techniques often have no formal training in the theory and practice of molecular dynamics simulation, leading to the possibility of these simulations being treated as a `black box' analysis technique. This ar
The manuscript is devoted to optimal control for a class of linear positive systems with linear objective function and linear constraints. The solution to the corresponding Bellman equation is a linear value function, which can be found by linear programming.
Looking ahead, the quest for environmental sustainability may turn out to be the most important political challenge of the twenty-first century. Though consensus is growing about some of the policy objectives like climate stability, political attitudes to these issues remain highly contested. Political parties seem to differ on both ontological assessments (how severe are the problems) and remedia
Construction of the MAX IV facility started early this year. The facility will include two storage rings for the production of synchrotron radiation. The 3 GeV ring will house insertion devices for the production of x-rays while the 1.5 GeV ring will serve UV and IR users. Recently, the lattices for the storage rings in the MAX IV facility were updated. In the 3 GeV storage ring the vertical beam
