- The automotive E/E architectures are evolving from the traditional distributed architectures to upcoming consolidated domain architectures and possibly future centralised architectures. This paper demonstrates modelling and timing analysis of real-time embedded systems on contemporary automotive E/E architectures using the Rubus-ICE tool suite. The Rubus concept and tool suite, developed and evolved based on close academic-industrial collaboration, have been used in the automotive industry for over 25 years. The paper also demonstrates recent extensions and discusses proposals to support the modelling and timing analysis of the systems on future E/E architectures.

- The aim of the pilot study was to explore the reactions of individuals with dementia to an interactive robotic cat and their relatives’ and professional caregivers’ experiences regarding its usability, function, and effects. Method The pilot study had an intervention, mixed-methods design1 and was conducted in two stages. A quantitative single-case study2 including individuals with dementia, and a qualitative interview study3, including relatives and professional caregivers, were conducted. JustoCat® is an interactive robotic pet developed using reminiscence therapy as a framework4. The development of JustoCat is based on promising work with the robotic seal, PARO5,6. However, the inventors of JustoCat assumed that a seal would not appeal in reminiscence therapy, a robotic cat was supposed appeal to individuals’ memories of cats. There was also the idea of downscaled, advanced technology based on the hypothesis of a robotic cat’s functional reliability and lower cost. The construction of JustoCat (e.g., easy-to-change fur facilitating personalized use, washable fur) was developed following Swedish hygiene routines required in nursing homes and hospital settings. Results & Discussion In the Western world, the majority of individuals with dementia spend the last part of their lives in nursing homes or dementia care homes. Some individuals with dementia could increase their well-being with different therapies, for example massage, singing, music or by the company of pets. The current pilot study of four individuals with dementia and their relatives and professional caregivers showed interesting results. First, living with severe dementia is a situation with ups and downs concerning quality of life and agitated behavior, as presented in the single-case study design. Second, the analysis of the interviews shows the positive effects of the robotic cat providing stimulation, comfort, and peace to individuals living with dementia. Third, professional caregivers and relatives found the robotic cat to be a useful, reliable, and multifunctional tool in their relationships with the participants6.

Outcome of Stroke Prevention : Analyses Based on Data from Riks-Stroke and Other Swedish National Registers
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this thesis was to explore variations in stroke prevention and the effect of prevention on outcome. The studies were based on patients registered in the Swedish Stroke Register between 2001 and 2009 and although used to different extents in each paper, additional information was retrieved through linkage to The National Patient Register, the Cause of Death Register, the Prescribed Drug Register and the Total Population Register.Cardiovascular risk factors were prevalent among ischemic stroke (IS) patients; however, they were not always prescribed the drugs recommended, and increasing age was an important negative predictor (Paper I).After IS, the rate of hemorrhage in patients prescribed antiplatelet agents (2.4 per 100 person-years) was double to results from randomized controlled trails, but was similar for patients prescribed warfarin (2.5 per 100 person-years). Age ≥75 years and previous hemorrhage were associated with a moderately increased risk of future hemorrhage (Paper II).Among IS patients with atrial fibrillation, one-third was prescribed warfarin and two-thirds were prescribed antiplatelets. After adjustment for a propensity score (used to adjust for the non-randomized design), warfarin was associated with a reduced risk of death (0.67; 95% CI, 0.63-0.71) (Paper III). The rate of subsequent hemorrhagic stroke was 0.4 per 100 person-years and the risk did not change (HR 1.04; 95% CI, 0.73-1.48) when later years of the 2000s (inclusion period 2005-8: follow-up until 2009) was compared with earlier years (inclusion period 2001-4: follow-up until 2005) (Paper IV, cohort).Although the risk of first-ever hemorrhagic stroke more than doubled with warfarin than without, the risk did not change between 2006 and 2009 (Paper IV, case-control).In summary, the prescription of secondary preventive drugs varies with age, even though cardiovascular risk factors are prevalent in all ages. The risk of death and hemorrhage are affected by the type of antithrombotic prescribed. Therefore, it is important individual’s stroke and bleeding risks in stroke prevention are assessed.

Bokkapitel (refereegranskat)abstract
- Inspired by a three-year Creative University ‘arena' initiative at Luleå University of Technology in Sweden, an international team of faculty researchers conducted an exploratory study in 2005, which aimed to investigate the efficacy of an interactive design and evaluation process for technology-enabled collaborative learning environments. This applied research approach was designed as a collaborative evaluation process for co-creation of technology-enabled, learningfocused physical and virtual ‘learning commons.' Faculty researchers from Sweden and the United States used Soft Systems Methodology tools, including the Process for Organisational Meanings (POM) model, to guide sixty-two students' participatory co-design and evaluation activities. In this paper, the POM evaluation model is explained and related to the Japanese concept Ba. Application of the models is illustrated within the context of student learning through boundary crossing information exchange and knowledge creation. As evidenced in their iterative and interactive evaluative recommendations, students' learning outcomes included development of improved capabilities for identifying socio-technical elements of distributed learning environments, suggesting that student beneficiaries can successfully reflect upon their experiences and provide valuable evaluation insights. In addition, when this evaluation is iterative, students' insights into project management, software needs, and services design can improve their technology-enabled learning experiences. Concluding comments explore the efficacy of the POM model implementation for guiding other learning-focused, user-centric initiatives, which aim to promote interdisciplinary, or boundary crossing, exchanges concurrent with advancing team-based knowledge creation proficiencies among project participants.

The Water Apocalypse : Venice desert cities and utopian arcologies in Southwestern dystopian fiction
- 2016
-
Konferensbidrag (refereegranskat)abstract
- Numerous stories have, and are being written in both criticism and literature about the future of the U.S. Southwest, and pretty much always said future is considered to be closely linked to the vicissitudes of water. The Southwest could be regarded as an undisciplined environment, forcing U.S. environmentalists to get over the color green while some of the population faces a drought by painting the grass of their front yards into that same color. In a disciplinary work that combines ecocriticism, political ecology and decolonial theories this presentation analyzes the way in which different Southwestern cultural groups are interlinked with the environmental degradation of the region, mostly due to the mismanagement of water. The struggles over water rights portrayed in the novel Alburquerque (1992), by the renown Chicano author Rudolfo Anaya, become very real when one reads the posts and news about the water-demanding Santolina sprawl development currently proposed for Albuquerque’s West side. In the same line, a lush sprawl development called “Venice” is proposed in Leslie Marmon Silko’s Almanac of the Dead (1991). On another tone, Paolo Bacigalupi’s last novel, The Water Knife (2015) presents arcologies (self-contained, self-sufficient buildings) as an option to scape what he perceives will be a hellish region when climate change worsens and water underground levels are eventually depleted. Migration, xenophobia and environmental re-adaptation become then central issues to consider. A nuanced analysis of these dystopian narratives brings into question current decision making around water management in the Southwest through the decolonial perspectives of the authors. If one argues that the environmental degradation of the arid Southwest is partly a consequence of the cultural oppression of the native local inhabitants, by imposing an inappropriate socio-environmental culture over the region, dystopian novels such as these become all the more relevant when proposing alternative futures.

- This work examines the effects of manufacturing induced voids on the postbuckling behavior of delaminated unidirectional composites. In the finite element model developed, a through-width delamination is introduced close to one surface of a flat panel, and a void is placed in the delamination plane ahead of each delamination front. The panel is subjected to compression in the fiber direction. The postbuckling delamination growth is studied by calculating the strain energy release rate (SERR) using the virtual crack closure technique. Local stress analyses of the region near the delamination front are also performed to further investigate the void effects. It is found that although the presence of void does not significantly alter the postbuckling transverse displacement of the delaminated panel, the induced stress perturbation by the void affects the SERR. The Mode II SERR as well as the total SERR increase depending on the size of the void and its distance from the delamination front. Since the Mode I SERR shows non-monotonic behavior with the applied load, the effects of voids are studied on its maximum value.

"Women in Groups Can Help Each and Learn from Each Other? : The Role of Homosocial Practices within Women's Social Networks in Building Local Gender Contracts
- 2016

Ingår i: Géneros: Multidisciplinary Journal of Gender Studies. - : Hipatia Press. - 2014-3613. ; 5:3, s. 1072-1095
-
Tidskriftsartikel (refereegranskat)abstract
- Feminist scholars struggle to articulate gender relations in different contexts. Using the concept of local gender contract - a place specific agreement of gender relations, we explore how women’s networks challenge or shift gender contracts in their communities. Based on two empirical case studies of women´s groups from Eastern Africa and Thai migrants in Sweden, we show gender contracts are challenged through women’s homosocial activities. We highlight tensions between gender contracts and the women’s goals revealing a complicated process of assent and resistance. This study expands gender contract theoretically and provides a way to understand vulnerable women’s activities.
