Conference paper (peer-reviewed)abstract
- In this pictorial paper, we present a series of drawing conversations held between two humans, mediated by computational GAN models. We consider how this creative collaboration is affected by the hybrid inclusion of more-than-human participants in the form of watercolour and artificial intelligence. Our drawing experiments were an extension of our search for new ways of seeing and telling, which includes a reflection of the extent to which more-than-human elements took part in our creative process. We discuss our tendencies to form strange interpretations and assign meaning to the unpredictable and ambiguous spaces we created with them. We further speculate on the characteristic material agencies they revealed in our interactions with them. Finally, we contend how such collaborations are already and always embedded and embodied in our ways of seeing and knowing in design and creativity research.

A dual Newton strategy for tree-sparse quadratic programs and its implementation in the open-source software treeQP
- 2019
-
In: International Journal of Robust and Nonlinear Control. - : Wiley. - 1099-1239 .- 1049-8923. ; 29:8, s. 2438-2457
-
Journal article (peer-reviewed)abstract
- This paper presents a dual Newton scheme for tree-sparse quadratic programs as they may arise in the field of stochastic programming. Previous work suggests to introduce auxiliary variables to decompose the tree into scenarios and use Newton's method to solve a dual problem formulation. Following a different approach, we apply the same principle directly on the tree-sparse problem, avoiding the increase in dimensionality. In combination with a tailored algorithm for the calculation of the step direction, which is typically the most expensive operation per iteration, the proposed algorithm achieves a linear complexity in the number of nodes and supports parallel processing of the tree branches in a stage-wise fashion. An open-source implementation of the presented dual Newton strategy is publicly available in treeQP, a toolbox of open-source solvers for tree-sparse quadratic programs.

Upscaling Of Reactive Flows In Domains With Moving Oscillating Boundaries
- 2014

Journal article (peer-reviewed)abstract
- We consider the flow and transport of chemically reactive substances (precursors) in a channel over substrates having complex geometry. In particular, these substrates are in the form of trenches forming oscillating boundaries. The precursors react at the boundaries and get deposited. The deposited layers lead to changes in the geometry and are explicitly taken into account. Consequently, the system forms a free boundary problem. Using formal asymptotic techniques, we obtain the upscaled equations for the system where these equations are defined on a domain with flat boundaries. This provides a huge gain in computational time. Numerical experiments show the effectiveness of the upscaling process.

Quantification of population exposure to NO2, PM2.5 and PM10 and estimated health impacts
- 2018
-
Reports (other academic/artistic)abstract
- In this study population exposure to annual mean concentrations of NO2, PM10 and PM2.5 in ambient air has been quantified, and the health and associated economic consequences have been calculated based on these results. To allow application of known exposure-response functions for assessment of health effects this study exclusively focus on regional and urban background concentrations. Nearly the entire Swedish population was exposed to concentrations below the environmental standards, and 97 %, 78 % and 77 % was exposed to concentrations below the respective specifications of the environmental objective for NO2, PM10 and PM2.5. The highest concentrations of NO2 and PM were found in the most polluted central parts of our largest cities.Excess mortality was used as the main health indicator. The total number of excess deaths due to air pollution exposure was estimated to be 7600 in 2015. Of these, we estimated that approximately 3600 deaths per year were associated with exposure to regional background, 900 from local wood burning, 215 due to road dust and approximately 2850 deaths per year from vehicle exhaust.Based on these results the health impacts from exposure to NO2 and PM2.5 were conservatively estimated to cause socio-economic costs of ~56 billion Krona in 2015. Just absence from work and studies was estimated to cause socio-economic costs of ~0.4% of GDP in Sweden.

Planering och utformning för ett ökat gående : Litteraturstudie, expertseminarium och trafik- och stadsplanerares syn på utemiljöns förutsättningar för gångtrafik
- 2012

Reports (other academic/artistic)abstract
- Trafikverket (The Swedish Transport Administration) provides funding for the project"Traffic Planning to Support Increased Walking – Systematic Improvement of Conditions forTravelling by Foot ". The project studies how pedestrians choose their route, why somephenomena become obstacles/are perceived as risky or, on the contrary, encourage walking.This report, the first in the project, includes a literature review, interviews with traffic andurban planners in local government, and an expert seminar. The findings of the three studieswill then serve as a basis for further work.Interviews of local government contacts and the expert seminar are considered to be verysuccessful working methods to find out about the opinions and experience of those currentlyworking with walking-related issues. All participants have been willing to assist and to sharetheir work and experience and were aware of the role of walking in the overall transportsystem, and its part in a sustainable transport system.The study has led to the conclusion that the concepts choice of means of transport – choice ofroute –built environment (for pedestrians) have been shown to be key in the sphere ofplanning for pedestrians and walking as a mode of transport. It is also of key importance topromote walking as a mode of transport where there are positive effects on health.Society needs to give greater scope to walking-related issues and to establish the idea ofpedestrian traffic as a norm, thereby raising its status. This work also includes defining therelevant actors relating to walking-related issues.It is also of interest to make an assessment of the groups which it is easiest to encourage towalk, and to investigate and describe the difference between everyday travel for a specificpurpose, to work and school, and walking for recreation and exercise in order to be better ableto improve planning for walking as a mode of transport.There is insufficient data to describe and quantify walking and there is a lack of methods tomeasure walking. The knowledge of town planning, which is still at a general level regardingthe network and the density of the pedestrian network, should also be highlighted.The overall conclusion is that it is important to demonstrate the importance of walking, andthat walking as a mode of transport should be a normative component of planning.
