Forskningsöversikt (refereegranskat)abstract
- In 2017, the Event Horizon Telescope (EHT) Collaboration succeeded in capturing the first direct image of the center of the M87 galaxy. The asymmetric ring morphology and size are consistent with theoretical expectations for a weakly accreting supermassive black hole of mass ∼6.5 × 109 M o˙. The EHTC also partnered with several international facilities in space and on the ground, to arrange an extensive, quasi-simultaneous multi-wavelength campaign. This Letter presents the results and analysis of this campaign, as well as the multi-wavelength data as a legacy data repository. We captured M87 in a historically low state, and the core flux dominates over HST-1 at high energies, making it possible to combine core flux constraints with the more spatially precise very long baseline interferometry data. We present the most complete simultaneous multi-wavelength spectrum of the active nucleus to date, and discuss the complexity and caveats of combining data from different spatial scales into one broadband spectrum. We apply two heuristic, isotropic leptonic single-zone models to provide insight into the basic source properties, but conclude that a structured jet is necessary to explain M87's spectrum. We can exclude that the simultaneous γ-ray emission is produced via inverse Compton emission in the same region producing the EHT mm-band emission, and further conclude that the γ-rays can only be produced in the inner jets (inward of HST-1) if there are strongly particle-dominated regions. Direct synchrotron emission from accelerated protons and secondaries cannot yet be excluded.

The DEVICE Project: Development of Educational Programs with a Specific Focus on Design for Children
- 2013
-
Ingår i: ACM Proceedings of Interaction Design for Children, IDC'13. - New York, NY, USA : ACM. - 9781450319188 ; , s. 360-363
-
Konferensbidrag (refereegranskat)abstract
- This paper describes the aim and preliminary results obtained during the first year of “DEVICE: DEsign for Vulnerable generatIons- Children and Elderly” project. The aim of the project is to develop new educational programs for students and professional with a specific focus on designing for vulnerable generations mainly children and elderly, and it is here focused on children. The paper describes the methodology and results of the state of the art and training needs analysis undertaken within the project. Preliminary results consist of a training needs list that will be the basis for the development of modules for teaching.

Comparison and analysis of user and stakeholder needs across different countries
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The current deliverable aims at presenting the results of the analysis of stakeholder needs, in order to have support for selecting the most relevant use cases. For the identification of user requirements of all stakeholders relevant to school transportation different methods were used:- Focus groups with representatives of one user or stakeholder group- Workshops with different stakeholders- 2 questionnaire surveys (Questionaire A: Road Experts, Questionaire B: children, parents and bus drivers)Problems and needs in the following areas were subject of discussions, interviews and questionnaires:- Behaviour of road users counteracting with school buses- Behaviour of pupils on the school bus and while entering and exiting the same- Design of bus stops- Protection of pupils on the school bus- Condition of school buses- Education of school bus drivers- Education of pupils concerning school transportation- Information flow- Route to/from school- Special needs of children with disabilitiesResults show that the organisation of school transport varies between countries and even within a country. Stakeholders underline the importance of consistent regulations and clear responsibilities as a basis for a safe way to school by bus.

Increasing Focus on Vulnerable Generations in Design Teaching: the DEVICE Project
- 2013
-
Ingår i: Human Factors and Ergonomics Society Europe Chapter Annual Meeting.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The DEVICE project aspires to bridge traditional industrial design programs with ergonomics, usability concepts and user experience approaches with a specific focus on vulnerable generations. It intends to address the need to modernize and develop educational programs with a specific focus on vulnerable generations, mainly children and elderly, and to become a milestone towards the modernization of design education. To improve the design practice in the area of design for children, it is necessary not only to study and improve methodology, but also to transfer the gained knowledge to new generations of designers in order to ensure its use in design. We wish to contribute to the community by bringing up the discussion on how to transform our knowledge and teach how to design for children.

Adaptation of water resources systems to changing society and environment : a statement by the International Association of Hydrological Sciences
- 2016
-
Ingår i: Hydrological Sciences Journal. - : Taylor & Francis Group. - 0262-6667 .- 2150-3435. ; 61:16, s. 2803-2817
-
Forskningsöversikt (refereegranskat)abstract
- We explore how to address the challenges of adaptation of water resources systems under changing conditions by supporting flexible, resilient and low-regret solutions, coupled with on-going monitoring and evaluation. This will require improved understanding of the linkages between biophysical and social aspects in order to better anticipate the possible future co-evolution of water systems and society. We also present a call to enhance the dialogue and foster the actions of governments, the international scientific community, research funding agencies and additional stakeholders in order to develop effective solutions to support water resources systems adaptation. Finally, we call the scientific community to a renewed and unified effort to deliver an innovative message to stakeholders. Water science is essential to resolve the water crisis, but the effectiveness of solutions depends, inter alia, on the capability of scientists to deliver a new, coherent and technical vision for the future development of water systems.

Show Me Your Best Trick! - Teaching Design for Vulnerable Generations: Children and Elderly
- 2013
-
Ingår i: ACM Proceedings of CHItaly 2013.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The workshop address how designers of the future canbuild social innovation for vulnerable generations andthereby address important social challenges, and is a forumwhere educators from different fields within design canmeet and exchange experiences from teaching. Theworkshop intends to bring together educators, designers,and practitioners to explore the sensitive issues regardingdesigning technical solutions for vulnerable generations, todiscuss training needs from different perspectives, and toshare best practice methods to teach designers how todesign technologies for vulnerable generations - elderly andchildren.
