- Drive-thru-Internet is a scenario in cooperative intelligent transportation systems (C-ITSs), where a road-side unit (RSU) provides multimedia services to vehicles that pass by. Performance of the drive-thru-Internet depends on various factors, including data traffic intensity, vehicle traffic density, and radio-link quality within the coverage area of the RSU, and must be evaluated at the stage of system design in order to fulfill the quality-of-service requirements of the customers in C-ITS. In this paper, we present an analytical framework that models downlink traffic in a drive-thru-Internet scenario by means of a multidimensional Markov process: the packet arrivals in the RSU buffer constitute Poisson processes and the transmission times are exponentially distributed. Taking into account the state space explosion problem associated with multidimensional Markov processes, we use iterative perturbation techniques to calculate the stationary distribution of the Markov chain. Our numerical results reveal that the proposed approach yields accurate estimates of various performance metrics, such as the mean queue content and the mean packet delay for a wide range of workloads. © 2019 IEEE.

Conference paper (peer-reviewed)abstract
- We report on a tool prototype for model-based testing of cyber-physical systems. Our starting point is a hybrid-system model specified in a domain-specific language called Acumen. Our prototype tool is implemented in Matlab and covers three stages of model-based testing, namely, test-case generation, test-case execution, and conformance analysis. We have applied our implementation to a number of typical examples of cyber-physical systems in order to analyze its applicability. In this paper, we report on the result of applying the prototype tool on a DC-DC boost converter. © Springer International Publishing Switzerland 2015

Book chapter (peer-reviewed)abstract
- Cyber-physical systems (CPSs) are the result of the integration of connected computer systems with the physical world. They feature complex interactions that go beyond traditional communication schemes and protocols in computer systems. One distinguished feature of such complex interactions is the tight coupling between discrete and continuous interactions, captured by hybrid system models.Due to the complexity of CPSs, providing rigorous and model-based analysis methods and tools for verifying correctness of such systems is of the utmost importance. Model-based testing (MBT) is one such verification technique that can be used for checking the conformance of an implementation of a system to its specification (model).In this chapter, we first review the main concepts and techniques in MBT. Subsequently, we review the most common modeling formalisms for CPSs, with focus on hybrid system models. Subsequently, we provide a brief overview of conformance relations and conformance testing techniques for CPSs. © 2017 Elsevier Inc. All rights reserved.

Journal article (peer-reviewed)abstract
- The health sector is very specific and difficult market for firms to access and deal with. The main reasons for this is that the healthcare systems are in continuous change, the co-creation processes in hospitals are complicated involving many different actors which also affects on firms commercialization and internationalization approaches. However, there is a growing demand of health services and the sector is growing also due to the COVID situation, that has been dramatically speeding up the digitalization of the healthcare services in the hospital settings. Approaching international hospital markets is, however, challenging for the start-up companies. On their journey they are facing a resistance, that they have to overcome in many different ways. The aim of this paper is to increase understanding how a start-up can overcome hospital resistance in an international innovation co-creation process. The results of are based on in depth case study in which the data collection was done over the four years of data gathering. The paper highlights how start-up companies can overcome the resistance in the international innovation co-creation in the hospital markets. It shows the importance of different activities, actors, capabilities and international activities in different phases of the international innovation co-creation journey. © 2022

Egyptian women's attitudes and beliefs about female genital cutting and its association with childhood maltreatment
- 2007
-
In: Nursing and Health Sciences. - Carlton, Vic, Australia : Blackwell Publishing. - 1441-0745 .- 1442-2018. ; 9:4, s. 270-276
-
Journal article (peer-reviewed)abstract
- This study aimed to establish Egyptian women's attitudes and beliefs about female genital cutting (FGC) or mutilation by applying a questionnaire module about violence to a subsample of 5249 married women from a total of 19 474 women who participated in the 2005 Egypt Demographic Health Survey. Women were interviewed to determine if they had been exposed to marital violence in the year prior to the survey, their attitudes and beliefs about FGC, and if they physically abused their children. The association of beliefs about FGC with maternal physical abuse was examined, adjusting for exposure to marital violence and other socio-demographic variables. Of the women surveyed 16.4% and 3.4% had been exposed to physical and sexual violence, respectively, during the year prior to the survey. Around 76% of the women surveyed intended to continue the FGC practice, and 69.8% had slapped or hit their children during the year prior to the survey. Holding positive beliefs about the practice of FGC or intending to continue it was associated with maternal physical abuse and this has significant implications for health and welfare workers in Egypt and for society in general.

Predicting institutional long-term care admission in dementia: a mixed-methods study of informal caregivers' reports
- 2015
-
In: Journal of Advanced Nursing. - Chichester : Wiley. - 0309-2402 .- 1365-2648. ; 71:6, s. 1351-1362
-
Journal article (peer-reviewed)abstract
- AimTo investigate agreement between: (1) expected reasons and actual reasons for admission of people with dementia according to informal caregivers; (2) scores on measurement instruments prior to admission and the actual reasons for admission according to informal caregivers. BackgroundTimely admission of people with dementia is a crucial issue. Information is highly warranted on whether informal caregivers are capable of prior identification of causes of admission and, can thus be considered a reliable prospective source on causes of admission. DesignA cohort study among informal caregivers of people with dementia who made a transition to institutional long-term care. MethodsQualitative data on the expected and actual reasons for admission were collected via open-ended questions at baseline and follow-up. Furthermore, at baseline, data were collected using measurement instruments to measure pre-admission characteristics. Interviews took place between November 2010-April 2012. After categorizing the answers, the agreement between the expected and actual reasons was calculated. Furthermore, bivariate associations were calculated between the actual reasons for admission and scores on corresponding measurement instruments. Results/FindingsFor most informal caregivers, there was agreement between their statements on the expected reason and the actual reason for admission. A third of the caregivers showed no conformity. Bivariate associations showed that there is also agreement between the actual reasons for admission and scores on corresponding measurement instruments. ConclusionInformal caregivers can be considered reliable sources of information regarding what causes the admission of a person with dementia. Professional care should anticipate informal caregivers' statements and collaborate with them to strive for timely and appropriate admission.

Cocreating injury prevention training for youth team handball : bridging theory and practice
- 2022
-
In: BMJ Open Sport and Exercise Medicine. - London : BMJ Publishing Group Ltd. - 2055-7647. ; 8:2
-
Journal article (peer-reviewed)abstract
- Although it is advocated that end-users are engaged in developing evidence-based injury prevention training to enhance the implementation, this rarely happens. The € Implementing injury Prevention training ROutines in TEams and Clubs in youth Team handball (I-PROTECT)' uses an ecological participatory design incorporating the perspectives of multiple stakeholders throughout the project. Within the I-PROTECT project, the current study aimed to describe the development of holistic injury prevention training specifically for youth handball players through using knowledge from both end-users (coaches and players) and researchers/handball experts. Employing action evaluation within participatory action research, the cyclical development process included three phases: research team preparation, handball expert-based preparation and end-user evaluation to develop injury prevention training incorporating both physical and psychological perspectives. To grow the knowledge of the interdisciplinary research team, rethinking was conducted within and between phases based on participants' contributions. Researchers and end-users cocreated examples of handball-specific exercises, including injury prevention physical principles (movement technique for upper and lower extremities, respectively, and muscle strength) combined with psychological aspects (increase end-user motivation, task focus and body awareness) to integrate into warm-up and skills training within handball practice. A cyclical development process that engaged researchers/handball experts and end-users to cocreate evidence-based, theory-informed and context-specific injury prevention training specifically for youth handball players generated a first pilot version of exercises including physical principles combined with psychological aspects to be integrated within handball practice. © 2022 BMJ Publishing Group.

Acceptabilitetsbedömningar av ena meningar – syntaktiska och informationsstrukturella begränsningar.
- 2023

In: Book of abstract. - : Linnaeus University Press. - 9789189709720

Conference paper (other academic/artistic)abstract
- Svenskan har två plurala obestämda artiklar: ena och några. Bruket av ena är dock mycket begränsat; artikeln tycks fungera endast i beskrivande, värderande och rematiska nominalfraser (Teleman et al. 1999, s. 410). I Collberg och Agebjörns (2023) korpusstudie förekom ena företrädesvis i predikativer, som i Barnen är ena riktiga vildingar. Artikeln förekom också i utbrutna led och egentliga subjekt samt undantagsvis i objekt. Däremot förekom den aldrig i subjekt eller adverbial och aldrig i topikaliserade fraser. Föreliggande studie undersöker i vilken utsträckning detta begränsade bruk av den plurala obestämda artikeln ena styrs av syntaktiska respektive informationsstrukturella faktorer. Med en experimentellt designad enkät testas hur acceptabilitetsbedömningar av meningar med ena beror dels på nominalfrasens grammatiska funktion, dels på dess informationsstrukturella funktion, operationaliserad som position i relation till meningens verb. Som kontrollvillkor används motsvarande meningar med default-artikeln några. Preliminära resultat visar att ena fungerar lika bra som några i predikativer och utbrutna led, sämre än några i subjekt, egentliga subjekt och objekt samt inte alls i adverbial. Nominalfrasens position i relation till verbet verkar inte påverka bedömningarna av ena-meningarna mer än bedömningarna av några-meningarna. Sammantaget tyder detta på att bruket av den plurala obestämda artikeln ena styrs av syntaktiska snarare än informationsstrukturella begränsningar.

Några, ena eller ∅? : Obestämda artiklar i plurala, beskrivande predikativer
- 2024
-
Conference paper (peer-reviewed)abstract
- Svenska singulara predikativa nominalfraser kan uppträda med eller utan obestämda artikel. Artikeln en används typiskt när predikativen beskriver subjektet medan ∅ används när predikativen klassificerar det, exempelvis genom att tillskriva det en yrkestillhörighet. Även artikeln någon uppträder i beskrivande predikativer, men framför allt i icke-affirmativa satser(Teleman et al. 1999). I plurala beskrivande predikativer är artikelbruket mer varierat. Oavsett om satsen affirmativ eller inte kan några, ∅ och ena användas, den sista framför allt i värderande nominalfraser i informella kontexter (se Collberg & Agebjörn 2022). Vad som styr valet mellan dessa tre är oklart.Föreliggande experimentella studie bidrar till att fylla denna kunskapslucka genom att besvara följande forskningsfråga: Hur påverkas acceptabilitetsbedömningar av deklarativa affirmativahuvudsatser med plurala beskrivande predikativer av (i) valet av artikel, (ii) nominalfrasens position i satsen samt (iii) nominalfrasens lexikala innehåll? Nästan 600 förstaspråkstalare av svenska bedömde tolv meningar med plurala predikativer, hälften positivt och hälften negativt värderande. Varje mening förekom i sex versioner, så att varje artikel, inkluderat ∅, uppträdde både pre- och postverbalt. Dessa versioner fördelades över sex listor så att samtliga deltagare fick bedöma en mening av varje typ utan att någon fick bedöma flera versioner av samma mening. Faktorerna artikel (några/ena/∅), position (preverbal/postverbal) och värdering(positiv/negativ), samt interaktionerna mellan dessa, inkluderades i en regressionsmodell som predicerar acceptabilitetsbedömningarna.Analysen visar att artikeln några bedömdes som signifikant sämre än både ena och ∅, medanskillnaden mellan ena och ∅ var obefintlig. Preverbala predikativer bedömdes generellt som sämre är postverbala, och denna negativa effekt av topikalisering var signifikant större för några än för ena och ∅, medan skillnaden mellan de två senare återigen var obefintlig.Dessutom bedömdes de positiva predikativerna generellt som sämre än de negativa, och denna effekt var signifikant större för ena än för ∅ och signifikant större för ∅ än för några. Sammantaget indikerar dessa resultat att ena eller ∅, snarare än några, är det omarkerade valet av artikel i plurala beskrivande predikativer. Sämst fungerar alltså några i preverbala negativt värderande predikativer. Valet mellan ena och ∅ styrs i sin tur av huruvida nominalfrasen är positivt eller negativt värderande. Slutligen tyder interaktionerna mellan artikel och position på att valet av artikel även påverkas av nominalfrasens informationsstrukturella status.

Conference paper (peer-reviewed)abstract
- This paper presents a way of building modular systems with a powerful optical interconnection network. Each module, placed on a Printed Circuit Board (PCB), has a generic optical communication interface with a simple electronic router. Together with optical switching using micro-electromechanical system (MEMS) technology, packet switching over reconfigurable topologies is possible. The interconnection system gives the possibility to integrate electronics with optics without changing existing PCB technology. Great interest from industry is therefore expected and the cost advantages are several: reuse of module designs, module upgrades without changing the PCB, low-cost conventional PCB technology, etc. In the version described in this paper, the interconnection system has 48 bidirectional optical channels for intra-PCB communication on each board. For inter-PCB communication, a backplane with 192 bidirectional optical channels supports communication between twelve PCBs. With 2.5 Gbit/s per optical channel in each direction, the aggregated intra-PCB bit rate is 120 Gbit/s full duplex (on each PCB) while the aggregated inter-PCB bit rate is 480 Gbit/s full duplex. A case study shows the feasibility of the interconnection system in a parallel processing system for radar signal processing.
