- Urbanization is one of the major current trends in society. Cities around the world are looking into 'smart' solutions based on information and communication technology to deal with the challenges that result from this development. Mobility is one of the most important areas to address, and system-of-systems solutions where vehicles and infrastructure are connected have a potential to improve urban transportation in many aspects. In this paper, current initiatives related to mobility in smart cities around the world are surveyed, and this is complemented with input from focus groups of transportation stakeholders to identify the important aspects of the problem. Based on this, challenges related to the application of systems-ofsystems in urban mobility are identified.

Konferensbidrag (refereegranskat)abstract
- This paper investigates user perceptions of continuous identity as agents migrate between different embodiments. It reports an experiment seeking to establish whether migrating or not migrating the interaction memory of the agent would affect the user's perception of consistent agent identity over different embodiments. The experiment involved a treasure hunt in which a virtual agent migrated from a screen to a mobile phone in order to accompany a user while they searched for clues. A total of 45 subjects took part in three different conditions with 15 subjects in each. The outcome showed that the presence of memory affected the competence users ascribed to the virtual agent. However it had no significant effect on a strong perception of consistent identity across multiple embodiments.

Dialing for Displays: Session Initiation Protocol for Opportunistic Augmentation
- 2006. - 1
-
Konferensbidrag (refereegranskat)abstract
- Opportunistic augmentation denotes connecting a personal mobile device to another device to gain a transient advantage for the user. For example, a mobile phone user might borrow a large display and keyboard from a desktop personal computer. This uniquely ubiquitous computing activity requires effective device and service discovery as well as appropriate media usable across two or more devices. In this paper we show how Session Initiation Protocol (SIP), the call signaling protocol for Voice over IP, effectively separates discovery from media-rendering selection in opportunistic augmentation. This separation improves system flexibility while allowing users or system administrators to choose the most appropriate discovery technologies for the environment. We also describe two phone-centric discovery mechanisms and demonstrate the practicality of the system by implementation and use in a test environment.

Models and Tools for Distributed User Interface Development
- 2012
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The way we interact with computers and computer systems are constantly changing as technology evolves. A current trend is that users interact with multiple andinterconnected devices on a daily basis. They are beginning to request ways and means of dividing and spreading their applications acrossthese devices.Distributed user interfaces (DUIs) have been proposed as a means ofdistributing programs over multiple interconnected devices through theuser interface (UI). DUIs represent a fundamental change foruser-interface design, enabling new ways of developing distributedsystems that, for instance, support runtime reorganization ofUIs. However developing DUIs presents a far more complex task compared totraditional UI development, due to the inherent complexity thatarises from combining UI development with distributed systems. Thetraditional approach in software engineering and computer science toovercoming complexity is to build tools and frameworks, to allowfor good code reuse and higher level of abstraction for applicationprogramers.Conventional GUI programming tools and frameworks are not developedto support DUIs specifically. In this thesis we explore key issues increating new programming tools and frameworks (APIs) for DUI-based UIdevelopment. We also present and discuss the DUI framework Marve,which adds DUI support to Java Swing.A unique feature of Marve is that it is designedfor industrial-scale development, extending a standard UIframework. The framework has beentested and evaluated in a project where an operator control stationsystem was developed.

Human papillomavirus in sinonasal inverted papilloma, recurrent respiratory papilloma and non-malignant tonsils
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Human papillomavirus (HPV) is known to cause recurrent respiratory papilloma (RRP) and certain types of oropharyngeal cancer. HPV has also been associated with sinonasal inverted papilloma (SIP). HPV transmission routes are under investigation and the conviction is that the infection occurs sexually at an adult stage, however, vertical transmission at birth with a dormant viral condition until disease eruption/co-activation has been stated as a possibility.Purpose: The purpose of this work was to contribute to the understanding of HPV related chronic diseases in the airway. Specific aims were: 1. To increase understanding regarding changes in the immune system as well as of the glycosaminoglycan hyaluronan in patients with RRP. 2. To evaluate prevalence of HPV and its surrogate marker p16 in SIP as well as HPV, p16 and Epstein-Barr virus (EBV) in benign tonsillar disease. HPV and EBV in non-malignant tonsillar disease were studied due to the fact that incidence of HPV positive tonsillar cancer is increasing and the time of viral infection is unknown.Methods: A phenotypic characterization of peripheral blood from 16 RRP patients and 12 age-matched controls, using immunoflow cytometry, and monoclonal antibodies against differentiation and activation markers, was performed. The cytokine mRNA profile of monocytes, T helper-, T cytotoxic-, and NK cells was assessed using RT-qPCR. 54 SIP samples were studied of which 53 were available for analyzation with PCR. Genotype screening for 18 high risk and six low risk HPV types was performed using the PapilloCheck® HPV-screening test (a PCR method). 54 samples were immunohistochemically (IHC) stained for p16. Biopsies from vocal folds (VFs) and false vocal folds (FVFs) were collected from 24 patients with RRP, 12 were randomly selected to histochemistry for Hyaluronan (HA) and IHC staining for CD44 in the epithelium, stroma and RRP lesions. The remaining 12 patients were analyzed for HA molecular mass distribution with a gas-phase electrophoretic molecular mobility analyzer (GEMMA). Eight VF samples and four FVF samples were successfully analyzed. Biopsies from 40 non-malignant tonsils were analyzed using Papillocheck® for HPV, IHC for p16 and EBER analysis for EBV.Results: We found a dominance of cytotoxic T cells, activated NK cells, and high numbers of stressed MIC A/B (MHC class I chain-related molecule A/B) expressing lymphocytes. The HPV analysis was successful for 38 SIP samples and two (5%) were positive for HPV 11. Notably, p16 was present in the epithelia of all samples and in the papilloma portions in 37 of 38 samples. We found extensive HA staining in the stroma of both VFs and FVFs. CD44 was expressed throughout the epithelium, stroma, and RRP lesions in both FVFs and VFs, it did however, not concur with the expression of HA. Very high mass HA was found in both VFs and FVFs, though more variation regarding amounts of HA was seen in the VFs compared to FVFs. No HPV was found in non-malignant tonsils, the p16 levels were low and the counted EBER positive cells showed great variation in numbers.Conclusions: Our findings demonstrate an immune dysregulation with inverted CD4+/CD8+ ratio and aberrant cytokine mRNA production in RRP patients, compared to healthy controls. We concluded that p16 cannot be used as a surrogate marker for high-risk HPV-infection in SIP and that HPV incidence was low (5%). CD44 does not seem to bind to HA, which might explain the noninflammatory response previously described in RRP. Very high mass HA possibly crosslinked was seen in both VFs and FVFs. A possibility to counteract inflammatory crosslinking of HA may be found for medical treatment options in RRP.

Always-On + Adoption – a method for longitudinal studies
- 2012. - 5
-
Konferensbidrag (refereegranskat)abstract
- We will discuss an approach for conducting long term studies of companionship technologies – technologies intended for more intimate relationships with people. We draw from our work of conducting several qualitative long-term user studies of people’s relationship with robotic companions and mobile devices in order to develop a methodology where the initial bond with the artifact is based on a more intense experience. After this initial phase referred to as Always On the relationship will fade over to the adoption phase where the more traditional long-term use can be studied. Most recently we are trying out this approach for studying people’s experience of an online social game that features virtual agents.

Konferensbidrag (refereegranskat)abstract
- Mobile ActDresses is a design concept where existing practices of accessorizing, customization and manipulation of a physical mobile device is coupled with the behaviour of its software. With this interactivity demonstrator we will provide a hands on experience of doing this kind of playful manipulation. We provide two examples for how to implement Mobile ActDresses using quick'n dirty hacks to create custom shells and jewellery for controlling the behaviour of the phone.
