Book chapter (peer-reviewed)abstract
- When technologies for distributed activities develop, in particular the rapidly developing mobile technology, a larger part of our time will be spent connected to our various distributed contexts. When we meet physically we bring technology, both artifacts and services, which enable us to participate in these non-local contexts. Potentially this is a threat to focused and efficient activities due to the intrusiveness of the technology. Our aim is to contribute to the restoration of a number of the desirable properties of traditional local technology-free contexts. The intrusiveness itself is caused by at least four typical phenomena that have influenced current technology: • Focus-demanding and clearly distinguishable artifacts like phones or PCs explicitly mediate interaction with the distributed context • The functionality of services is traditionally based upon the assumption that communication is a deterministic flow of passive information, which for example, does not include information of the participants´ current context • Services in general perform individually and without coordinated communication schemes • The switches between contexts introduce a high cognitive load as each distributed context typically has its own system of characteristic objects and rules. In the FEEL project, we have developed a system called “Focused, Efficient and Enjoyable Local Activities with Intrusiveness Management” (FEELIM) that constitutes an intermediate alternative between the technology-dense and technology-free environments, which addresses the problems cited above. This research is based on a collaborative and cooperative setting where problems of intrusiveness management are confounded by several users meeting and cooperating together as opposed to isolated users dealing with similar problems of interruption management (Chen 2004; Ho 2005).

Wireless Foresight: Scenarios of the Mobile World in 2015
- 2003
-
Book (other academic/artistic)abstract
- We are entering exciting times. After the decade when the Internet and the cell-phone changed our lives and working habits, these two technologies are about to merge. At the same time, the industry is going through one of its worst crises ever. At this crossroads, the future can take any direction. Up or down. Success or failure. This is the website of the final report from the scenario project Wireless Foresight. The report deals with the state of the wireless industry in 2015 and presents four scenarios of the future: »Wireless Explosion – Creative Destruction«, »Slow Motion«, »Rediscovering Harmony«, and »Big Moguls and Snoopy Governments«. From the scenarios, important areas for technological research are identified. A number of critical challenges facing industry are identified: the high cost for infrastructure, the slow spectrum release, the stampeding system complexity, radiation, battery capacity, and the threat of a disruptive market change facing the telco industry. The project has been initiated by Wireless@KTH, a research and educational center formed by the Royal Institute of Technology (KTH) in cooperation with industry.

Influence of acidic pH on keratinocyte function and re-epithelialisation of human in vitro wounds
- 2015
-
In: Journal of Plastic Surgery and Hand Surgery. - : Taylor & Francis. - 2000-656X .- 2000-6764. ; 49:6, s. 346-352
-
Journal article (peer-reviewed)abstract
- Background: Chronic wounds are one of the greatest challenges for the healthcare system. Today, a plethora of dressings are used in the treatment of these wounds, each with specific influence on the wound environment. Due to differences in the permeability of the dressings the use will result in differences in the pH balance in the wound bed. However, little is known about how changes in the pH in the wound environment affect the different phases of the healing process. Aim: The aim of the present study was to investigate the effects of acidic pH on the regeneration phase by studying keratinocyte function in vitro and re-epithelialisation in an in vitro model of human skin. Results:In vitro assays showed reduced viability and migration rates in human keratinocytes when pH was lowered. Real time PCR revealed differential expression of genes related to wound healing and environmental impairment. Tissue culture showed no re-epithelialisation of wounds subjected to pH 5.0 and moderate re-epithelialisation at pH 6.0, compared to controls at pH 7.4. Conclusion: The results indicate that lowering pH down to pH 5.0 in wounds is counterproductive in aspect of keratinocyte function which is crucial for successful wound healing.

Identifying unmet rehabilitation needs in patients after stroke with a graphic rehab-compassTM
- 2018
-
In: Journal of Stroke & Cerebrovascular Diseases. - : Elsevier. - 1052-3057 .- 1532-8511. ; 27:11, s. 3224-3235
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Unmet rehabilitation needs are common among stroke survivors. We aimed to evaluate whether a comprehensive graphic "Rehab-Compass," a novel combination of structured patient-reported outcome measures, was feasible and useful in facilitating a capture of patients' rehabilitation needs in clinical practice.METHODS: A new graphic overview of broad unmet rehabilitation needs covers deficits in functioning, daily activity, participation, and quality of life. It was constructed by using 5 patient-oriented, well-validated, and reliable existing instruments with converted data into a 0 (worst outcome) to 100 (best outcome) scale but unchanged in terms of variable properties. Satisfaction of the Rehab-CompassTM was studied by a qualitative interview of 9 patients with stroke and 3 clinicians. Practical feasibility and capacity of the instrument were evaluated in a cross-sectionalstudy with 48 patients at 5-month follow-ups after subarachnoid hemorrhage.RESULTS: The Rehab-CompassTM identified and graphically visualized a panoramic view of the multidimensional needs over time which was completed before clinical consultation. The Rehab-CompassTM appeared to be feasible and time-efficientin clinical use. The interviews of both patients and clinicians showed high satisfaction when using the Rehab-CompassTM graph. In the studied stroke patients, the Rehab-CompassTM identified memory and processing information, fatigue, mood, and pain after subarachnoid hemorrhage as the most common problems.CONCLUSIONS: The graphic Rehab-CompassTM seems to be a feasible, useful, and time-saving tool for identification of unmet rehabilitation needs among stroke survivors in clinical practice. Further research is needed to make the Rehab-CompassTM more concise and evaluate the instrument among different stroke subgroups.

Laser-Ultrasound-Based Grain Size Gauge for the Hot Strip Mill
- 2022
-
In: Applied Sciences. - : MDPI AG. - 2076-3417. ; 12:19
-
Journal article (peer-reviewed)abstract
- The paper summarizes the creation of a robust online grain size gauge for a hot strip mill. A method and algorithm for calculating the grain size from the measured ultrasonic attenuation is presented. This new method is self-calibrating, does not rely on a geometrical reference sample and can cope with the effects of diffraction on the attenuation. The model is based on 52 quenched samples measured with more than 23,000 laser ultrasonics shots and has a correlation coefficient R2 of 0.8. Typical online laser ultrasonic measurements from the hot strip mill and the calculated grain size versus length are presented for a couple of steel strips.

Expressive messaging on mobile platforms
- 2001. - 2
-
Conference paper (peer-reviewed)abstract
- This paper presents design requirements for expressive, avatar-based multi-modal messaging on mobile platforms. It is argued that expressive messaging needs to exploit context of peers, embodied appearance and behaviour, in combination with text. Our approach allows strong expressiveness and yet simple, on the fly message compositions required in a mobile, noisy setting. Technical challenges for a user ready prototype are sketched. It is argued that the context of usage between work-related stationary terminals and mobile ones is radically different.
