- By the Coulomb breakup of 17Ne, the time-reversed reaction 15O(2p,γ)17Ne has been studied. This reaction might play an important role in the rp process, as a break-out reaction of the hot CNO cycle. The secondary 17Ne ion beam with an energy of 500 MeV/nucleon has been dissociated in a Pb target. The reaction products have been detected with the LAND-R3B experimental setup at GSI. The preliminary differential and integral Coulomb dissociation cross section sCoul has been determined, which then will be converted into a photo-absorption cross section sphoto, and a two-proton radiative capture cross section σcap. Additionally, information about the structure of the 17Ne, a potential two-proton halo nucleus, will be received. The analysis is in progress. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

- The unbound isotopes 10Li, 12Li and 13Li have been observed after nucleon-knockout reactions at relativistic energies with 11Li and 14Be beams impinging on a liquid hydrogen target. The channels , and were analysed in the ALADIN-LAND setup at GSI. The 10Li data confirm earlier findings, while the 12Li and 13Li nuclei were observed for the first time. The relative-energy spectrum shows that the ground state of 12Li can be described as a virtual s-state with a scattering length of -13.7(1.6) fm. A broad energy spectrum was found for the channel. Based on the assumption that the relative-energy spectrum is dominated by a correlated background presumably stemming from initial correlations in the 14Be ground-state, evidence for a 13Li resonance at 1.47(31) MeV above the threshold with a width around 2 MeV has been found.

Properties of the 7He ground state from 8He neutron knockout
- 2009
-
Ingår i: Physics Letters B. - : Elsevier BV. - 0370-2693. ; 679:3, s. 191-196
-
Tidskriftsartikel (refereegranskat)abstract
- The unbound nucleus 7He, produced in neutron-knockout reactions with a 240 MeV/u 8He beam in a liquid-hydrogen target, has been studied in an experiment at the ALADIN-LAND setup at GSI. From an R-matrix analysis the resonance parameters for 7He as well as the spectroscopic factor for the 6He(0+) + n configuration in its ground-state have been obtained. The spectroscopic factor is 0.61 confirming that 7He is not a pure single-particle state. An analysis of 5He data from neutron-knockout reactions of 6He in a carbon target reveals the presence of an s-wave component at low energies in the α+n relative energy spectrum. A possible low-lying exited state in 7He observed in neutron knockout data from 8He in a carbon target and tentatively interpreted as a Iπ=1/2− state, could not be observed in the present experiment. Possible explanations of the shape difference between the 7He resonance obtained in the two knockout reactions are discussed in terms of target-dependence or different reaction mechanisms at relativistic energies.

Forskningsöversikt (refereegranskat)abstract
- This literature review puts forward a comparison between the traditional seller, usually represented by classic Industrial Organization (IO) models, and system providers, which are illustrated by Product Service System (PSS) models. A multidisciplinary systematic literature review, that compares PSS and IO models, is conducted, and ends up in to define PSS as a technology. It highlights the differences and similarities between classic IO and classic PSS and evaluate the weakness and strengths of different models. In total, 148 articles from different disciplines have been investigated, and a different understanding of PSS is provided. A new IO framework, that considers classic sellers and PSSs providers, is established to preserve PSS specificities and stress the role of policy maker and competition for PSSs expansion.

Nordic Post-Graduate Sustainable Design and Engineering Research from a Supervisor Perspective
- 2008
-
Ingår i: NordDesign 2008. - Tallin, Estonia. ; , s. 171-180
-
Konferensbidrag (refereegranskat)abstract
- The multi- and interdisciplinary field of sustainable product innovation is rapidly expanding as an arena for scientific research. Universities in Nordic countries can be considered as an exponent of this type of research, with active research groups in, among others, Göteborg, Helsinki, Lund, Lyngby, Linköping and Trondheim. In the context of a Nordforsk funded project, seven second generation PhD supervisors from these universities, who have been active in this field for many years, discuss funding, publication, research traditions, education and supervision practices related to PhD research in this field. A number of recommendations to improve current practices are made, including the mapping currently existing differences in different academic institutions, studying the cross-over learning effects between academica and non-academic partners, and the development of ‘quality indicators’ of research in the SPI domain.

LCA of Biogas Through Anaerobic Digestion from the Organic Fraction of Municipal Solid Waste (OFMSW) Compared to Incineration of the Waste

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Production of biogas through anaerobic digestion (AD) from the organic fraction of minucipal solid waste (OFMSW) was compared to incineration of the waste. At the moment, almost all of the OFMSW in Singapore is incinerated. Three different scales of biogas plants were compared to incineration: one large-scale biogas plant that can treat half of all OFMSW in Singapore; one medium- scale biogas plant about 15 times smaller than the large one; and one small-scale biogas plant that can treat waste from e.g. a shopping centre or food centre. Two alternatives for utilization of the biogas were also compared, generation of electricity and the use of the biogas in heavy vehicles. The combination of the different scales and the different utilization gives the six different scenarios. By using life cycle assessment (LCA) the different scenarios were compared in terms of global warming potential (GWP), acidification, eutrophication, energy use and land use. The results show that biogas production creates less environmental impact than incineration. The use of the gas as a vehicle fuel creates a bigger decrease of GWP, acidification and eutrophication than when using the gas for electricity generation. The prevention of leakage of biogas during production and upgrading is crucial for the environmental impact on GWP. A leakage of only a few percent of the produced gas will lead to a loss of all the gain in saved GHG-emissions.

State of the Art of Design Methods for Resource Efficient and Effective Solutions : Report from “Product and Service Design Methods for REES” Project of Mistra REES program
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This document reports on the results of work packages (WPs) 2.1 and 2.2 in Project 2 (Product and Service Design Methods for REES, i.e. resource efficient and effective solutions) of the Mistra REES program (www.mistrarees.se). WP 2.1 and WP 2.2 aim at documenting current use of design methods and deriving requirements for design methods, respectively. The document only covers results from the scientific literature review, while other reports to be developed will cover results, for instance, from the interview study and the design session with industry partners in the Mistra REES consortium. The results of the literature review will be a foundation for WP 2.3, which aims at developing new design methods. Note that methods here include frameworks, tools, and support for designers.The document describes current use (i.e., “as‐is” status) of product and service design methods when designing REES, as well as requirements for product and service design methods for REES (i.e., information soon‐to‐be). Both of these are results of analysis in different phases of an early phase of design for REES. Those phases consist of requirement specification, conceptual design, and analysis and evaluation, which can be ordered temporally along the design process.From the overall analysis, found is a lack of insights about methods for designing REES, although potentially useful methods are available. This means advancement of knowledge is insufficient for industry within the subject, which is relatively new. It may also mean the developed methods are not precisely according to the needs of companies. This shows a high potential of developing new methods in the rest of the project.More specifically, in the requirement specification, the literature shows that potentially useful methods include QFD (Quality Function Deployment), the Taguchi method, the Kano model, and data mining, among others. In the conceptual design, numerous methods exist, and most of them were developed in an older context, where REES was not as relevant as today. Those methods include DfX methods (X denotes cost, assembly, etc.), the functional block diagram, the checklist, morphological analysis, and the Fishbone Diagram. Only a few seem to be used widely in industry today. In the analysis and evaluation, available methods include Lifecycle Simulation, Lifecycle Costing, multi‐criteria decision making, and the Analytical Hierarchy Process. Most of the methods or tools available specialise in one area. This is a problem when developing an integrated offering of products and services, because designers need to have a holistic perspective for that.Regarding requirements for methods to be developed, the authors analysed literature as follows. In the requirement specification, requirements originating from multiple aspects and actors need to be taken into account. Since an enormous amount of data and information can be collected from products and by technologies implemented today, a huge opportunity is presented for enhancing requirement specification. Yet, there seems to be little insights to take this opportunity. In conceptual design, it is important to identify and involve relevant actors as well as their requirements according to a number of scientific reports. Especially, interaction between the relevant actors seems to be critical to be implemented. In analysis and evaluation, various pieces of earlier research works recommend different features to be implemented in methods. These features include visualization of information and information flows, graphical user interface, multiple users’ participation, and ability to handle environmental information, uncertainty and risk.

Support for Designing Resource Efficient and Effective Solutions: Current Use and Requirements by Swedish Industry : Report from “Product and Service Design Support for REES” Project of Mistra REES program
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This document reports on the results of work packages (WPs) 2.1 and 2.2 in Project 2 (Product and Service Design Support for REES, i.e. resource efficient and effective solutions) of the Mistra REES program (www.mistrarees.se). WP 2.1 and WP 2.2 aim at documenting current use of design support and deriving requirements for design support, respectively. The document only covers results from interviews with companies, while the other reports will cover results, for instance, from scientific literature review (ISRN: LIU‐IEI‐RR‐‐17/00264—SE) and the design session with industry partners in the Mistra REES consortium. The results of this research into industrial practice will be a foundation for WP 2.3, which aims at developing new design support for designers.The document describes current use (i.e., “as‐is” status) of product and service design support when designing REES, as well as requirements for product and service design support for REES (i.e., information soon‐to‐be). Both of these are results of analysis in different phases of an early phase of design for REES. Those phases consist of requirement specification, conceptual design, and analysis and evaluation, which can be ordered temporally along the design process.Eight Sweden‐based companies that provide products and services in different sectors and work on resource efficiency participated in the interviews. They vary in terms of the size: from small to large. 24 individual interviews were conducted in total with the length being between 54 and 117 minutes (with two additional shorter follow up interviews via phone/skype). The 24 interviews were carried out all with face to face between May and July, 2016. The result from each company is described per section in this report, while cross‐company analysis will be made in a separate document.

Requirements for REES design support : a survey among large companies and SMEs
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report presents the results of a survey carried out during 2017-2018 among 11 different companies as part of the REES programme (www.mistrarees.se) work package (WP) 2.2 of Project 2 (the project concerning design in the programme). The objective of the survey was to identify the most important requirements for design support that is being developed for REES designers in the manufacturing industry. The survey comprises results from a total of 25 participants from 5 SMEs and 6 large companies, which included 8 participants from SMEs and 17 from large companies. This classification was made according to the EU commission (2015) definition of SMEs (< 250 employees and ≤ EUR 50 million in annual turnover). The results presented are divided into Section 1 where an overview of the survey and the method is presented and section 2 results, where consolidated data and comparison between large companies and SMES is provided.
