- This paper is based on a user-centric innovation project, Free2Ride, which is seen as an example of community interaction that overcomes boundaries. The Free2Ride projects goal was to develop a piece of ICT safety equipment consisting of a sender (on the horse) and a receiver (application in a smartphone) to be used by equestrian club members during their everyday riding activities. We will answer the research question of what the characteristics of a boundary dialogue in user-centric innovation activities are. The aim of the paper is to propose a model describing the characteristics of boundary dialogue in user-centric innovation that involve different communities of practices such as ICT developers, users and researchers. An important element of that model is the mental wandering, inwards and outwards, by core members in a community. We discuss the temporal as well as the symbolic nature of the mental wandering during the boundary dialogue in user-centric innovation activities. We applied a combination of research approaches consisting of action research and engaged scholarship approach. The theoretical framework for analyzing our findings is communities of practices with a specific interest in boundary spanning and learning dialogues.

Konferensbidrag (refereegranskat)abstract
- This paper is based on studies of a living lab process, which is an open, user-centric, innovation approach, where several actors from industry, user groups and academia are involved. We aim to describe and analyze the dynamics in an innovation boundary context based on a living lab process. An action-oriented research approach was applied and the empirical results are from The Find Project (TFP), with the aim of customizing an ICT product based on the needs of a user group. The findings are analyzed from a community of practice perspective where the three different communities i) researchers from Halmstad Living Lab (HLL), ii) ICT developers (ICTD), and iii) next of kin's to demented elderly persons (NOKD) represented the units of analysis. The analysis identified several boundary situations that played a vital role for the innovation process. The contribution of our research to innovation theory is a process model describing the dynamics in an innovation boundary context with regard to boundary objects-in-use as well as to brokering. The research highlights two different levels of brokering: i) product/service brokering; and ii) process brokering.

A general control system structure for multi-terminal VSC-HVDC systems
- 2014
-
Ingår i: IEEE PES Innovative Smart Grid Technologies, Europe.
-
Konferensbidrag (refereegranskat)abstract
- Renewable technology expands geographically and in capacity. The long transmission distance and bulk power transfer involved make multi-terminal VSC-HVDC systems a key technology for future power systems. This expansion could be hampered by the pace of development of multi-terminal systems especially when standardization is not reached in hardware or the control system. A general control system structure is proposed in this paper, dividing the control system in control levels for primary and secondary control implementation and focusing on the interface among them for modularity and expandability. Uniform interfaces standardize data exchange and decouple the overall system control from the local substation control. A version of the control system is tested on a simplified model for different scenarios and number of terminals to demonstrate its functionality and ability to integrate additional terminals. The control system structure provides a platform where each part of the control system can be programmed independently.

Data Driven Continuous Improvement by Six Sigma in Aircraft Industry
- 2014
-
Ingår i: ENBIS-14 in Linz 21 – 25 September 2014.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Continuous improvements initiated by unsatisfactory output variation often require data or combinations of data from other up-stream variation sources than previously monitored. Three Six Sigma projects have been recently carried out in order to improve the process capability of welded components at GKN Aerospace. Common to these three projects are problems with the measurement systems and sub-sequent analysis related to the Key Characteristics (KC) evaluation. Parameters are traditionally monitored relative their individual requirements but not to the combined set of measures that form the KC. All three projects identified a need to establish a standardized procedure to develop data collection and analysis procedures relative specific KC based on downstream requirements in order to be able to evaluate KC baseline capability.The aim with this article is to recognize the development of an overall measurement system (containing probes, data collection routines and analysis procedures) as enabler of Continuous Improvement of downstream KC capability requirements.Note: GKN Aerospace is a Tier 2 supplier in the Aerospace business with a large variety of components that is available on more than 90% of all new engines.

The Scandinavian Ice Sheet: from MIS 4 to the end of the Last Glacial Maximum
- 2010

Ingår i: Boreas. - : Wiley. - 1502-3885 .- 0300-9483. ; 39:2, s. 410-435

Forskningsöversikt (refereegranskat)abstract
- Glacial rebound modelling, to establish constraints on past ice sheets from the observational evidence of palaeo-shoreline elevations, is well established for the post- Last Glacial Maximum (post-LGM) period, for which the observational evidence is relatively abundant and well distributed spatially and in time. This is particularly the case for Scandinavia. For the earlier part of the glacial cycle this evidence becomes increasingly sparse and uncertain such that, with the exception of the Eemian period, there are very few, if any, direct sea-level indicators that constrain any part of the Scandinavian Ice Sheet evolution before the LGM. Instead, we assume that ice-sheet basal conditions during Marine Isotope Stage 3 (MIS 3) are the same as those for the LGM, focus on establishing these conditions from the rebound analysis for the LGM and Lateglacial period, and then extrapolate to the earlier period using observationally constrained locations of the ice margins. The glacial rebound modelling and inversion follow previously established formulations, with the exception that the effects of water loading from proglacial lakes that form within the Baltic Basin and elsewhere have been included. The data set for the inversion of the sea- and lake-level data has been extended to include marine-limit data in order to extend the observational record further back in time. The result is a sequence of time slices for the Scandinavian Ice Sheet from the time of MIS 4 to the Lateglacial that are characterized by frozen basal conditions until late in the LGM interval when rapid thinning occurred in the eastern and southern sectors of the ice sheet. The primary function of these models is as an interpolator between the fragmentary observational constraints and to produce quantitative models for the glaciation history with predictive capabilities, for example regarding the evolution of the Baltic Basin.

Politicians online : Identifying current research opportunities
- 2014
-
Ingår i: First Monday. - : University of Illinois Libraries. - 1396-0466. ; 19:4
-
Tidskriftsartikel (refereegranskat)abstract
- For more than a decade, researchers have shown interest in how politicians make use of the Internet for a variety of purposes. Based on critical assessments of previous online political communication scholarship, this paper identifies a series of overlooked areas of research that should be of interest for researchers concerned with how politicians make use of online technologies. Specifically, three such research opportunities are introduced. First, we suggest that research should attempt to move beyond dichotomization, such as conceiving of the Internet as either bringing about revolutionary changes or having a normalizing effect. Second, while there is a considerable body of knowledge regarding the activity of politicians during election campaigns, relatively little is known about the day–to–day communicative uses of the Internet at the hands of politicians. The third section argues that as political communication research has typically focused on national or international levels of study, scholars within the field should also make efforts to contribute to our knowledge of online practices at the hands of politicians at regional and local levels — something we label as studies at the micro level. In synthesizing the literature available regarding the use of the Internet at the hands of politicians, the paper concludes suggesting routes ahead for interested scholars.
