  • Soap-film coating : High-speed deposition of multilayer nanofilms
  • 2013
  • In: Scientific Reports. - Nature Publishing Group : Springer Science and Business Media LLC. - 2045-2322. ; 3, s. Art. no. 1477-
  • Journal article (peer-reviewed)abstract
    • The coating of thin films is applied in numerous fields and many methods are employed for the deposition of these films. Some coating techniques may deposit films at high speed; for example, ordinary printing paper is coated with micrometre-thick layers of clay at a speed of tens of meters per second. However, to coat nanometre thin films at high speed, vacuum techniques are typically required, which increases the complexity of the process. Here, we report a simple wet chemical method for the high-speed coating of films with thicknesses at the nanometre level. This soap-film coating technique is based on forcing a substrate through a soap film that contains nanomaterials. Molecules and nanomaterials can be deposited at a thickness ranging from less than a monolayer to several layers at speeds up to meters per second. We believe that the soap-film coating method is potentially important for industrial-scale nanotechnology.

  • Kartläggning av ägarskiften i företag : Utveckling och dokumentation av dataunderlag
  • 2014
  • Reports (other academic/artistic)abstract
    • Myndigheten för tillväxtpolitiska utvärderingar och analyser, Tillväxtanalys, har haft i uppdrag av regeringen att genomföra kartläggning och analys av ägarskiften i företag. Uppdraget omfattade även att göra jämförelser mellan generationsskiften och andra typer av ägarskiften som inte är åldersbaserade samt belysa möjligheten att följa upp företagens skifte och dynamik över tid. Tillväxtanalys lämnade i oktober 2013 en delrapportering av uppdraget som avser dels en kartläggning av åldersstrukturen i företagsstocken, dels en fördjupad analys av ägarskiften. Denna rapport är en redovisning av uppdragets sista del som innebär utveckling och dokumentation av dataunderlag för identifiering av ägarförändringar.SCB har på uppdrag av Tillväxtanalys undersökt möjligheten att bättre identifiera ägarskiften genom att integrera och göra en matchningskontroll av kompletterande uppgifter gällande delägare i fåmansaktiebolag som kan hämtas från Skatteverket, SKV, med redan befintlig information om företagsdynamik, vilken finns i Företagens och arbetsställenas dynamik, FAD, och den registerbaserade arbetsmarknadsstatisken, RAMS, på SCB. För att göra detta studeras företagens ägarskiften mellan åren 2010 och 2011. Uppdraget omfattar även att beskriva FAD gällande syfte, metodik och innehåll.Cirka 80 procent av samtliga företag oberoende av bolagsform överlevde mellan åren 2010 och 2011. Resterande företag har på något sätt förändrats. Företag läggs ned och andra startar som en del i strukturomvandlingen. Dessutom ser vi att många företag och arbetsställen byter ägare. Näringslivet visar på en stor dynamik och dynamiken omfattar många olika typer av förändringar.Bearbetningarna visar att det med hjälp av RAMS och SKV:s register går att följa och framställa uppgifter om ägarförändringar på ett bra sätt. Detta gäller både för fåmansaktiebolag, där det går att följa individuellt ägande, och för övriga juridiska former där förändringar i organisationsnummer kan spåras, vilket indikerar ändrade ägarförhållanden. Analysen visar att SKV:s register är ett bra komplement till RAMS och FAD och tillför ytterligare information. Samkörningen av dessa registerdata ger mer information än vad som kan fås ut av respektive registerkällor separat. Det går dessutom att koppla på annan information om anställda, omsättning och olika mått på lönsamhet från andra register.Tillväxtanalys rekommenderar därför att SCB får tillgång till register gällande ägarandelar från Skatteverket under en längre tidsperiod än enbart de undersökta åren. Detta för att kunna sammanställa en databas som möjliggör bättre och mer precisa analyser av olika dimensioner av näringslivsdynamik och ägarförändringar. Det vore dessutom önskvärt att denna databas görs tillgänglig för forskning och studier som ökar kunskapen om olika dimensioner av näringslivets strukturomvandling.

  • Bättre avfallshantering i Sundsvall : Mittuniversitetets slutrapport från förstudien
  • 2018
  • Reports (other academic/artistic)abstract
    • Förstudien syftar till att tillsammans med MittSverige Vatten & Avfall (MSVA) ta fram verktyg för att informera om vinsterna med källsortering och påverka för att nå en bättre, mer hållbar avfallshantering i Sundsvall. En hållbar avfallshantering bidrar till att ge förutsättningar för en hållbartillväxt och god livsmiljö i Sundsvall. I förstudien presenteras exempel och förslag på hur visualiseringar kan bidra till att förbättra avfallshanteringen i Sundsvalls kommun. Inom ramen för studien har också en Återbruksfestival genomförts i syfte att undersöka och uppmärksamma vad som slängs samt ge konkreta exempel på återvinning och återbruk. Vidare genomfördes ett seminarium baserat på underliggande arbete kring hur papper och kartong kan användas som material för att ersätta hushållsförpackningar i plast. Förstudien utgör också en del i arbetet mot visionen att initiera forskning i samverkan med de aktörer i regionen som kan se nytta av design och visualisering i sin egen verksamhet. Förstudien har också bidragit till att ge underlag för framtida inriktningar, förutsättningar, och forskningsfrågor inom visualisering och design.

  • Dielectric strength of γ-radiation cross-linked, high vinyl-content polyethylene
  • 2015
  • In: European Polymer Journal. - : Elsevier BV. - 0014-3057. ; 64, s. 101-107
  • Journal article (peer-reviewed)abstract
    • We explore γ-radiation cross-linking of high vinyl-content low-density polyethylene (LDPE) and its potential use as a high-voltage insulation material. Of the three investigated resins containing 1, 0.5 and 0.17 vinyl groups per 1000 carbons, respectively, only the highest vinyl-content material featured a sufficiently high gel content of more than 70% and hot-set elongation below 175%, when cross-linked with a γ-radiation dose of at least 68 kGy. Differential scanning calorimetry (DSC) and small-angle X-ray scattering (SAXS) reveal that neither the crystallinity nor the lamellar thickness of the highest vinyl-content LDPE are negatively affected by γ-radiation cross-linking. As a result, we find that the dielectric strength, as characterized by electrical tree initiation experiments, can be maintained upon γ-radiation cross-linking.

  • Digital visualisering i skolan : Mittuniversitetets slutrapport från förstudien
  • 2018
  • Reports (other academic/artistic)abstract
    • Den här studiens syfte har varit tvåfaldigt, nämligen att testa alternativa lärmetoder via ett digitalt läromedel i matematik i en kvasiexperimentell studie samt att tillämpa metoder av användarupplevelser för interaktiva visualiseringar, och därigenom öka kunskapen kring hur upplevd kvalitet beror på använd teknik. Pilotstudien sätter också fokus på flera angelägna områden inom skolutveckling både regionalt och nationellt samt viktiga aspekter när det gäller kopplingen teknik, pedagogik och utvärderingsmetoder inom “den tekniska delen”. Det förra handlar om sjunkande matematikresultat i skolan, praktiknära skolforskning, stärkt digital kompetens, visualisering och lärande samt forskning om visualisering och utvärdering. Den senare svarar på frågor om vilka tekniska lösningar som tidigare använts och med vilket syfte har de skapats samt hur visualiseringar har utvärderats enligt läroböcker och i forskningslitteratur. När det gäller elevernas resultat, en av de stora forskningsfrågorna i studien, så fann vi inga signifikanta skillnader mellan traditionell undervisning och undervisning med visualiseringsläromedlet (3D). Beträffande elevers attityder till matematikmomentet kan konstateras att i kontrollgruppen för årskurs 6 förbättrades attityden signifikans, men inte i klass 8. Gällande flickors och pojkars resultat och attityder kan vi konstatera att flickorna i båda klasserna hade bättre förkunskaper än pojkarna samt att i årskurs 6 var flickorna mer positiva till matematikmomentet än pojkarna i kontrollgruppen. Därutöver kan vi inte skönja några signifikanta skillnader. Andra viktiga rön i studien var att provkonstruktionen inte var optimal samt att tiden för provgenomförande har stor betydelse när på dagen det genomfördes. Andra resultat resultaten i den kvalitativa analysen pekar på positiva attityder och beteenden från eleverna vid arbetet med det visuella läromedlet. Elevernas samarbete och kommunikation förbättrades under lektionerna. Vidare pekade lärarna på att med 3D-läromedlet gavs större möjligheter till att stimulera flera sinnen under lärprocessen. En tydlig slutsats är att 3D-läromedlet är ett viktigt komplement i undervisningen, men kan inte användas helt självt. Vi kan varken sälla oss till de forskare som anser att 3D-visualisering är överlägset som läromedel för elevers resultat eller till de forskare som varnar för dess effekter för elevers kognitiva överbelastning.  Våra resultat ligger mer i linje med de slutsatser Skolforskningsinstitutet (2017) drar, nämligen att undervisning med digitala läromedel i matematik kan ha positiva effekter, men en lika effektiv undervisning kan möjligen designas på andra sätt. Däremot pekar resultaten i vår studie på ett flertal störningsmoment som kan ha påverkat möjliga resultat och behovet av god teknologin och välutvecklade programvaror. I studien har vi analyserat resultaten med hjälp av två övergripande ramverk för integrering av teknikstöd i lärande, SAMR och TPACK. Det förra ramverket bidrog med en taxonomi vid diskussionen av hur väl teknikens möjligheter tagits tillvara av läromedel och i läraktiviteter, det senare för en diskussion om de didaktiska frågeställningarna med fokus på teknikens roll. Båda aspekterna är högaktuella med tanke på den ökande digitaliseringen i skolan. Utifrån tidigare forskning och denna pilotstudie förstår vi att det är viktigt att designa forskningsmetoderna noggrant. En randomisering av grupper vore önskvärt. Prestandamått kan också vara svåra att välja. Tester där personer får utvärdera användbarhet (usability) och användarupplevelse (user experience, UX) baserade på både kvalitativa och kvantitativa metoder blir viktiga för själva användandet av tekniken, men det måste till ytterligare utvärderingar för att koppla tekniken och visualiseringen till kvaliteten i lärandet och undervisningen. Flera metoder behövs således och det blir viktigt med samarbete mellan olika ämnen och discipliner.

  • Surface characterization methods for quality assessment of polyethylene-coated paperboard
  • 2021
  • Licentiate thesis (other academic/artistic)abstract
    • In manufacturing processes, the quality of a product often depends on its surface, and careful control of surface properties is critical to meet customer requirements. A thin layer of polyethylene (PE) is applied to paperboard to increase barrier functionality and high optical quality of the product. For PE-coated paperboard, product quality inspection is performed at the end of the manufacturing process by taking a portion of the reel to the laboratory for quality inspection. These associated offline characterization methods are destructive and time consuming and are representative of only a small portion of the product.The overall goal of this thesis is to provide new methods to characterize the Surface properties of PE-coated paperboard. Specifically, to determine imaging techniques for measuring surface parameters that affect its barrier functionality and surface roughness.In this thesis, two methods for surface characterization of PE-coated paperboard are presented to quantify the two most important product-related quality parameters, i.e. barrier functionality and optical quality, which are affected by the presence of defects in the coating and by the surface roughness of the product, respectively. First, a full-Stokes imaging polarimeter (FSIP) is used to detect the presence of PE-coated material and to distinguish between coated and uncoated samples at the pixel level. Second, a three-dimensional scanning electron microscope (3D SEM) is employed to calculate the Surface roughness of PE-coated paperboard. These surface characterization techniques offer an advantage over the industry standard due to the high speed and non-contact nature of the measurement, while increasing the throughput of the sample surface parameters studied.A classification accuracy of 99, 74% is achieved using a FSIP to distinguish between PE- and non-PE-coated paperboard at pixel level. Using the 3D SEM technique to measure the topography of PE-coated samples results in a faster method that is comparable in accuracy to a chromatic confocal microscope (CCM). The surface roughness measured with the 3D SEM differs from the standard method by up to 6% and good agreement with statistical parameters is found.In general, surface analysis of PE-coated is often a complex and difficult task for imaging techniques and suitable methods need to be evaluated for their sensitivity to measure the desired surface parameters. The presented characterization techniques inspect larger areas of PE-coated paperboard compared to current industry standards. These methods provide a quantitative solution for surface characterization to inspect the surface parameters necessary to assure the product’s quality.

  • Surface topography characterization of high-quality PE coated paperboard using confocal chromatic microscope and 3D SEM stereo-photogrammetry technique
  • 2017
  • Conference paper (peer-reviewed)abstract
    • Coating paperboard enhances printability and optical quality of the product as well as other important properties like packaging performance and shelf-life. To obtain high quality products a quality control of the manufacturing process requires identifying those manufacturing parameters that affect it. Roughness measurement and characterization of coating thickness are examples of these control parameters. Optical instruments measuring these quantities range from laboratory equipment to in-line and on-line sensors. However, the variety of instruments and sometimes misunderstanding of their limitations generate uncorrelated measurements, which are no longer valid to their comparison. The new ISO 25178 standard for surface texture provides guidelines to metrologists to address some this problem. Here, we report a case study for surface characterization of high quality printing polyethylene (PE) coated paperboard for high quality printing, where surface roughness is a key parameter. Two imaging methods to create topographic measurements will be compared, i.e. a confocal chromatic microscope and a scanning electron microscope (SEM). For the latter, stereo photogrammetry is used and 3D topographic profiles are obtained from Alicona MeX software. Leach and Haitjema [Leach, R., & Haitjema, H. (2010). Bandwidth characteristics and comparisons of surface texture measuring instruments. Measurement Science and Technology, 21(3), 032001] addressed the topic on how to design comparisons when using different instruments for areal texture measurement. We use their bandwidth matching concept, since it provides an extension to the ISO 25178 guidelines, ensuring that the instrumentation used to characterize the samples are within its measuring limits and further analysis of the results can be correlated. It is important to adopt a good metrology practice in order to translate these parameters into our future work. We expect to extend these findings into a real-time optical sensor, which later can be implemented in an industrial manufacturing environment for high optical quality paper and paperboard.

  • Distinct cytoplasmic and nuclear functions of the stress induced protein DDIT3/CHOP/GADD153
  • 2012
  • In: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 7:4
  • Journal article (peer-reviewed)abstract
    • DDIT3, also known as GADD153 or CHOP, encodes a basic leucine zipper transcription factor of the dimer forming C/EBP family. DDIT3 is known as a key regulator of cellular stress response, but its target genes and functions are not well characterized. Here, we applied a genome wide microarray based expression analysis to identify DDIT3 target genes and functions. By analyzing cells carrying tamoxifen inducible DDIT3 expression constructs we show distinct gene expression profiles for cells with cytoplasmic and nuclear localized DDIT3. Of 175 target genes identified only 3 were regulated by DDIT3 in both cellular localizations. More than two thirds of the genes were downregulated, supporting a role for DDIT3 as a dominant negative factor that could act by either cytoplasmic or nuclear sequestration of dimer forming transcription factor partners. Functional annotation of target genes showed cell migration, proliferation and apoptosis/survival as the most affected categories. Cytoplasmic DDIT3 affected more migration associated genes, while nuclear DDIT3 regulated more cell cycle controlling genes. Cell culture experiments confirmed that cytoplasmic DDIT3 inhibited migration, while nuclear DDIT3 caused a G1 cell cycle arrest. Promoters of target genes showed no common sequence motifs, reflecting that DDIT3 forms heterodimers with several alternative transcription factors that bind to different motifs. We conclude that expression of cytoplasmic DDIT3 regulated 94 genes. Nuclear translocation of DDIT3 regulated 81 additional genes linked to functions already affected by cytoplasmic DDIT3. Characterization of DDIT3 regulated functions helps understanding its role in stress response and involvement in cancer and degenerative disorders.

  • Angular variations of reflectance and fluorescence from paper - the influence of fluorescent whitening agents and fillers
  • 2012
  • In: Final Program and Proceedings - IS and T/SID Color Imaging Conference. - Springfield, USA : The Society for Imaging Science and Technology. - 9780892083039 ; , s. 236-241
  • Conference paper (peer-reviewed)abstract
    • It has earlier been shown that light reflected from the bodyof paper exhibit anisotropic behavior. On the other hand, fluores-cence emission is often assumed to be distributed in a Lambertianmanner. The angular behavior of light reflected and fluorescedfrom paper is examined using measurements from a spectral go-niophotometer. The angular dependency of the radiance factorswas measured for a range of excitation wavelengths. Moreover,the influence of fillers and fluorescent whitening agents (FWA)on the anisotropy was studied. The measurements show that theanisotropy of the total radiance factor of paper decreases whenan increasing amount of FWA is added to the paper. The sameeffect was also observed when an increased amount of filler wasadded to the paper. In addition, it was shown that the presenceof fillers reduce the effect of the FWA. The results show that incomparison to the anisotropy of the total radiance factor from thepaper samples, the anisotropy of the fluorescence alone is negligi-ble. Hence, for paper samples containing FWA evenly distributedin the bulk, the fluorescence alone should not induce significantdifferences between color measuring instruments of different mea-surement geometries.

  • Separation of surface and bulk reflectance by absorption of bulk scattered light
  • 2013
  • In: Applied Optics. - : Optical Society of America. - 1559-128X .- 2155-3165. ; 52:19, s. 4749-4754
  • Journal article (peer-reviewed)abstract
    • A method is proposed for separating light reflected from turbid media with a rough surface into a bulkand a surface component. Dye is added to the sample, thereby increasing absorption and canceling bulkscattering. The remaining reflected light is surface reflectance, which can be subtracted from the totalreflectance of an undyed sample to obtain the bulk component. The method is applied to paper wherethe addition of dye is accomplished by inkjet printing. The results show that the bulk scattered light isefficiently canceled, and that both the spectrally neutral surface reflectance and the surface topographyof the undyed paper is maintained. The proposed method is particularly suitable for characterization ofdielectric, highly randomized materials with significant bulk reflectance and rough surfaces, which aredifficult to analyze with existing methods. A reliable separation method opens up for new ways of analyzing,e.g., biological tissues and optical coatings, and is also a valuable tool in the development of morecomprehensive reflectance models.

  • Gamma spectroscopy methodology for large amounts of environmental samples in Sweden 30 years after the Chernobyl accident
  • 2020
  • In: ND 2019. - : EDP Sciences. - 9782759891061
  • Conference paper (peer-reviewed)abstract
    • In a Swedish citizen science project, more than 200 elementary school classes participated in collecting fungi, soil samples, and droppings from deer and wild boar, from all over Sweden. The samples have been sent to a laboratory at Uppsala University where they are being analyzed through gamma spectroscopy with a shielded HPGe detector. The main objective is to scan the samples for 137Cs from the Chernobyl accident and compare the data with measurements from 1986, but uptake of naturally occuring radionuclides like 40K and radon daughters will also be determined. Together with the soil samples, transfer factors will be derived, and correlations for these factors will be sought for different species of fungi and soil types. The potential for correlating the results with different biological processes will also be investigated, in part through the collected animal droppings. This is a work in progress where the present status of the experimental setup and methodology are presented. Issues with the initial approach for corrections are discussed and preliminary results are presented.

  • Multipla naturhändelser i Sverige
  • 2021
  • Reports (other academic/artistic)abstract
    • Denna rapport syftar till att (i) redogöra för begreppet ’multipla naturhändelser’ och kunskapsläget kring interaktioner mellan olika naturhändelser, samt att (ii) fastställa vilka naturhändelser som är mest relevanta med hänsyn till beredskap och förmåga innanför Sveriges territoriala gränser. Översiktligt diskuteras dessutom förutsättningar för och behov av hantering av multipla naturhändelser. Rapporten innehåller en sammanställning av hur naturhändelser interagerar med varandra i vetenskaplig litteratur, en sammanställning av förekomst av naturhändelser i Sverige utifrån sekundärdata från myndigheter och en workshop med experter för att identifiera multipla naturhändelser med relevans för svenska förhållanden. Rapporten presenterar resultat från en första delstudie inom forskningsprojektet Effektiv hantering av multipla naturhändelser (EMMUNE), som finansieras av Myndigheten för samhällsskydd och beredskap (MSB) och Formas. Naturhändelser kan vara multipla på olika sätt. En primär naturhändelse kan direkt utlösa en eller flera andra naturhändelser. De sekundära händelserna kan sedan i sin tur orsaka ytterligare händelser, vilket skapar en kaskad av händelser. En naturhändelse kan också öka sannolikheten eller förutsättningen för en eller flera andra naturhändelser, exempelvis genom höga flöden eller långvarig torka. Det kan också inträffa flera naturhändelser som sammanfaller i tid och rum utan att händelserna är direkt relaterade till varandra. I rapporten redogörs för interaktioner mellan följande naturhändelser: jordbävning; tsunami; geofysiska jordrörelser och hydrologiska skred, ras och sättningar; vulkanutbrott; blixtnedslag; extremt höga respektive låga temperaturer; isstormar; översvämningar; torka; laviner; skogs- och markbränder; skadedjursangrepp; meteoriter; och geomagnetisk storm. En bedömning görs också av vilka naturhändelser som kan anses vara mest relevanta för Sverige i relation till vårt klimat och väder. Bedömningen grundar sig i litteraturstudien och det genomgångna materialet kring förekomst och magnitud och leder fram till att följande naturhändelser anses relevanta: laviner; kraftig vind; kraftig nederbörd; extrema temperaturer; blixturladdningar; översvämningar; ras och sättningar; torka; samt skog- och markbränder. De påverkas alla antingen direkt eller indirekt av klimategenskaper eller väderhändelser. Kunskapen om klimatförändringarnas påverkan på förekomsten av extrema väderförhållanden är varierande och innefattar olika grader av osäkerheter beroende av vilken typ av extremt förhållande det handlar om. I Sverige innefattar eller drivs multipla naturhändelser oftast av atmosfäriska eller hydrologiska händelser. De multipla naturhändelser som av experterna anses vara mest frekventa samt får allvarliga konsekvenser inkluderar antingen höga flöden eller skogsbrand i kombination med annan händelse. När det gäller kunskapsläget kring multipla naturhändelser visar litteraturstudien att det finns vetenskapligt stöd för en mängd olika interaktioner mellan naturhändelser. Experterna som deltog i vår workshop beskriver också att vissa naturhändelser, som exempelvis kustöversvämningar, oftast uppstår vid ”multipla” väderfenomen och att det finns många potentiella multipla interaktioner både kopplade till ett utgångsläge med långvarig torka och värme eller höga flöden i vattendrag. Sammantaget talar detta för att naturhändelser behöver betraktas mer utifrån ett multipelt perspektiv. Naturhändelser sker inte bara isolerat utan kan påverkas av eller påverka andra naturhändelsers förlopp, antingen genom ett direkt utlösande eller genom förändring av miljön som ökar sannolikheten för andra naturhändelser. I såväl forskning om naturhändelser och klimatförändringar som i forskning om hantering av naturhändelser har händelserna hittills främst betraktats en och en. Det genomgångna materialet indikerar inte att Sverige kommer att drabbas av några nya företeelser på nationell nivå, däremot är det troligt att frekvensen och magnituden för vissa av naturhändelserna kommer att öka i ett förändrat klimat. Det kan även finnas anledning att inkludera biologiska naturhändelser, såsom det gjordes i exempelvis MSB:s sammanställning av riskområden och scenarioanalyser (MSB 2015). För att öka medvetenheten om multipla naturhändelser beskrivs tre scenarier för multipla naturhändelser, 1. en situation med höga flöden i vattendrag där det oväntat inträffar ett kraftigt regn, 2. en situation med en torr sommar där det inträffar en värmebölja, och 3. en relativ nederbördsfattning senvinter och varm april med låg markfuktigheten där det uppstår en skogsbrand. Ett lågtryck drar sedan in som ger mycket kraftiga vindar varvid skogsbranden intensifieras och sprids. Redan när det gäller förekomst och omfattning av enskilda atmosfäriska eller hydrologiska händelser är det stora osäkerheter i befintliga prognoser och klimatförändringsprojektioner, även om det sannolikt kommer bli både starkare och mer frekvent förekomst av väderfenomen framgent. Att prognostisera och simulera multipla naturhändelser innefattar därmed ännu större osäkerheter. Beredskapen att hantera multipla naturhändelser kan gynnas av ett fortsatt fokus på konsekvensbaserade vädervarningssystem. Exempelvis att vid en period med höga flöden i vattendrag kunna informera att om detta fortsätter ökar risken för sekundära händelser exempelvis skred. Multipla naturhändelsers hantering skulle kunna underlättas genom att tillhandahålla information baserad på förutsättningar för olika naturhändelser på specifika platser, detta för att bedöma risken för sekundära naturhändelser under givna förutsättningar samt de möjliga konsekvenserna av multipla naturhändelser för en specifik plats. Det är därför viktigt att för de tänkta målgrupperna öka förmågan att kunna tolka sådan information och vädervarningar samt att målgrupperna i förväg haft möjlighet kartlägga tänkbara konsekvenser för olika naturhändelser så att behovet av insatser snabbare kan bedömas när en händelse inträffar.

  • Effect of Paper Properties on Electrical Conductivity and Pattern Definition for Silver Nanoparticle Inkjet Ink
  • 2012
  • In: Proceedings of LOPE-C 2012. - 9783000381225 ; , s. 115-119
  • Conference paper (peer-reviewed)abstract
    • In this work, electrical conductivity and print pattern definition isstudied for silver nanoparticle ink, printed on ten commerciallyavailable paper substrates. Interrelations and correlations betweenelectrical conductivity, print pattern definition and a set ofmeasured paper properties are analyzed with a multivariatestatistical method. The papers are characterized in terms ofabsorption rate, porosity, apparent surface energy, surfaceroughness and surface material content. The statistical analysisshows that electrical conductivity and print pattern definition arecorrelated. Conductivity and print definition are correlatedpositively with absorption rate and negatively with surfaceroughness. A model based on projection to latent structures (PLS) isbuilt from the measurement data, showing adequate values of modelfit and predictive ability. This suggests that the chosen propertiesand methods for surface characterization are relevant in estimatingoverall performance of inkjet-printed conductors on paper.Additionally, a qualitative examination of the nanoparticle layercharacteristic is conducted with SEM cross section microscopy.Some of the properties and mechanisms of importance to theconductivity of the printed conductors are highlighted, of whichsome are crucial for achieving conductivity. Physical characteristicsof a suitable paper surface should ideally include large absorptioncapability for the ink carrier, but most importantly, a characteristicpore size and surface roughness amplitude that are both smallcompared to the dry ink layer thickness. If these criteria are met,paper media can be a low cost, comparably high performancealternative for metal nanoparticle inks in printed electronics applications.

  • Scanning electron microscopy and atom probe tomography characterization of laser powder bed fusion precipitation strengthening nickel-based superalloy
  • 2023
  • In: Micron. - 0968-4328 .- 1878-4291. ; 171
  • Journal article (peer-reviewed)abstract
    • Atom probe tomography (APT) was utilized to supplement scanning electron microscopy (SEM) characterizationof a precipitation strengthening nickel-based superalloy, Alloy 247LC, processed by laser powder bed fusion (LPBF). It was observed that the material in the as-built condition had a relatively high strength. Using both SEMand APT, it was concluded that the high strength was not attributed to the typical precipitation strengtheningeffect of γ’. In the absence of γ’ it could be reasonably inferred that the numerous black dots observed in thecells/grains with SEM were dislocations and as such should be contributing significantly to the strengthening.Thus, the current investigation demonstrated that relatively high strengthening can be attained in L-PBF even inthe absence of precipitated γ’. Even though γ’ was not precipitated, the APT analysis displayed a nanometer scalepartitioning of Cr that could be contributing to the strengthening. After heat-treatment, γ’ was precipitated and itdemonstrated the expected high strengthening behavior. Al, Ta and Ti partitioned to γ’. The strong partitioningof Ta in γ’ is indicative that the element, together with Al and Ti, was contributing to the strain-age crackingoccurring during heat-treatment. Cr, Mo and Co partitioned to the matrix γ phase. Hf, Ta, Ti and W were found inthe carbides corroborating previous reports that they are MC.

  • Doctoral thesis (other academic/artistic)abstract
    • In a time where there is an increasing demand for easily accessible and up-to-date information, digital printing has become a link between traditional printed media and electronic media. Over the last years, applications such as variable data printing, personalised printing and print on demand have changed the way in which printed matter is produced and handled. The print quality of products produced by digital printing systems has improved considerably in recent years. The main reason for this improvement is better printer hardware but the printing paper is still a very influential factor. The two major technologies, inkjet and electrophotography and their respective applications put very different demands on the paper, mechanically, chemically and optically. Nevertheless, the differences in print quality across digital printing systems are decreasing, except for one area − colour reproduction. The growth of the market of consumer colour imaging products, such as digital printers and desktop printers, has been enormous during the last years. As a consequence of this, consumer expectations on colour reproduction have risen significantly, as even very small failures in colour reproduction can drastically reduce the visual impression of an otherwise impeccably reproduced image. Therefore, as consumer expectations continue to rise, a high and repeatable quality of colour image reproduction is a growing challenge for producers of digital printing devices as well as for paper producers. However, this is impossible to achieve without precise methods and routines to measure colour reproduction quality. The use of spectrophotometers for colour measurements of printed substrates is widely spread among paper producers as well as within the printing industry. Spectrophotometers are precise instruments for point-wise measurements. However, the measurement procedure is very time-consuming and therefore, faster methods for colour measurements are longed-for. If the spectrophotometers used today could be replaced with trichromatic capturing devices such as flatbed scanners or digital cameras, colour characterisation would be not only faster, but also less expensive. In addition, if the trichromatic devices are colorimetrically calibrated, spatial image information can be combined with colour information, making it possible to measure quality attributes related to colour image rendering that are impossible to capture with point-wise measurements. Today, flatbed scanners and digital cameras provide robust and high-quality image capturing capabilities at a relatively low cost. Furthermore, scanner and camera-based systems for automated objective measurements of print quality parameters have already become widely used tools for print quality measurements of print-related properties such as print mottle, sharpness and bleeding. However, the colour calibration of trichromatic capturing devices is not free from obstacles. In colour calibrations, where the aim is to measure colour of printed matter, knowledge about the properties of the capturing device, the printing substrate, the printing process and the printer function are all of great importance. In the work presented here, methods for colour characterisation of printing processes are proposed as well as methods for colour characterisation and calibration of trichromatic capturing devices. Furthermore, the media dependency problem inherent to colour calibrations of trichromatic capturing devices is discussed. Examples are given on how properties of the printed substrate, such as the content of fluorescent whitening agents, influence colour calibrations as well as colour measurements in general.

  • Learning to Make Safe Real-Time Decisions Under Uncertainty for Autonomous Robots
  • 2020
  • Doctoral thesis (other academic/artistic)abstract
    • Robots are increasingly expected to go beyond controlled environments in laboratories and factories, to act autonomously in real-world workplaces and public spaces. Autonomous robots navigating the real world have to contend with a great deal of uncertainty, which poses additional challenges. Uncertainty in the real world accrues from several sources. Some of it may originate from imperfect internal models of reality. Other uncertainty is inherent, a direct side effect of partial observability induced by sensor limitations and occlusions. Regardless of the source, the resulting decision problem is unfortunately computationally intractable under uncertainty. This poses a great challenge as the real world is also dynamic. It  will not pause while the robot computes a solution. Autonomous robots navigating among people, for example in traffic, need to be able to make split-second decisions. Uncertainty is therefore often neglected in practice, with potentially catastrophic consequences when something unexpected happens. The aim of this thesis is to leverage recent advances in machine learning to compute safe real-time approximations to decision-making under uncertainty for real-world robots. We explore a range of methods, from probabilistic to deep learning, as well as different combinations with optimization-based methods from robotics, planning and control. Driven by applications in robot navigation, and grounded in experiments with real autonomous quadcopters, we address several parts of this problem. From reducing uncertainty by learning better models, to directly approximating the decision problem itself, all the while attempting to satisfy both the safety and real-time requirements of real-world autonomy.

  • Conference paper (peer-reviewed)abstract
    • Aerial robots hold great potential for aiding Search and Rescue (SAR) efforts over large areas, such as during natural disasters. Traditional approaches typically search an area exhaustively, thereby ignoring that the density of victims varies based on predictable factors, such as the terrain, population density and the type of disaster. We present a probabilistic model to automate SAR planning, with explicit minimization of the expected time to discovery. The proposed model is a spatial point process with three interacting spatial fields for i) the point patterns of persons in the area, ii) the probability of detecting persons and iii) the probability of injury. This structure allows inclusion of informative priors from e.g. geographic or cell phone traffic data, while falling back to latent Gaussian processes when priors are missing or inaccurate. To solve this problem in real-time, we propose a combination of fast approximate inference using Integrated Nested Laplace Approximation (INLA), and a novel Monte Carlo tree search tailored to the problem. Experiments using data simulated from real world Geographic Information System (GIS) maps show that the framework outperforms competing approaches, finding many more injured in the crucial first hours.

  • Paperboard Coating Detection Based on Full-Stokes Imaging Polarimetry
  • 2021
  • In: Sensors. - : MDPI AG. - 1424-8220. ; 21:1
  • Journal article (peer-reviewed)abstract
    • The manufacturing of high-quality extruded low-density polyethylene (PE) paperboard intended for the food packaging industry relies on manual, intrusive, and destructive off-line inspection by the process operators to assess the overall quality and functionality of the product. Defects such as cracks, pinholes, and local thickness variations in the coating can occur at any location in the reel, affecting the sealable property of the product. To detect these defects locally, imaging systems must discriminate between the substrate and the coating. We propose an active full-Stokes imaging polarimetry for the classification of the PE-coated paperboard and its substrate (before applying the PE coating) from industrially manufactured samples. The optical system is based on vertically polarized illumination and a novel full-Stokes imaging polarimetry camera system. From the various parameters obtained by polarimetry measurements, we propose implementing feature selection based on the distance correlation statistical method and, subsequently, the implementation of a support vector machine algorithm that uses a nonlinear Gaussian kernel function. Our implementation achieves 99.74% classification accuracy. An imaging polarimetry system with high spatial resolution and pixel-wise metrological characteristics to provide polarization information, capable of material classification, can be used for in-process control of manufacturing coated paperboard.

  • Three-dimensional scanning electron microscopy used as a profilometer for the surface characterization of polyethylene-coated paperboard
  • 2021
  • In: Nordic Pulp & Paper Research Journal. - : Walter de Gruyter. - 0283-2631 .- 2000-0669. ; 36:2, s. 276-283
  • Journal article (peer-reviewed)abstract
    • In food packaging, low-density polyethylene (PE) coating is applied to paperboards to act as a functional barrier and to provide the smoothness required to enhance printability. These characteristics are related to the material’s surface roughness, the parameter monitored during the manufacturing process. Measurement of surface roughness using optical profilometry has gained importance in the paper industry. The optical instruments used to measure surface roughness are limited spatially by the relationship with the light wavelength at which they operate. A scanning electron microscope (SEM) is an alternative for overcoming the spatial resolution limitation, and the use of stereo-photogrammetry on SEM images can be seen as an alternative profilometry technique to measure surface roughness. In this investigation, the surface topography of industrially manufactured high-quality PE-coated paperboard was studied, comparing the SEM stereo-photogrammetry technique with a reference profilometry method, i. e., chromatic confocal microscopy (CCM). We found close agreement between the calculated surface roughness and the results of the techniques used and compared them according to the new ISO 25178 Geometric Product Specifications. We concluded that SEM stereo-photogrammetry provides comparable accurate alternative profilometry method for characterizing the surface roughness of PE-coated paperboard in the micrometer scale.

  • Latency impact on Quality of Experience in a virtual reality simulator for remote control of machines
  • 2020
  • In: Signal processing. Image communication. - : Elsevier. - 0923-5965 .- 1879-2677. ; 89
  • Journal article (peer-reviewed)abstract
    • In this article, we have investigated a VR simulator of a forestry crane used for loading logs onto a truck. We have mainly studied the Quality of Experience (QoE) aspects that may be relevant for task completion, and whether there are any discomfort related symptoms experienced during the task execution. QoE experiments were designed to capture the general subjective experience of using the simulator, and to study task performance. The focus was to study the effects of latency on the subjective experience, with regards to delays in the crane control interface. Subjective studies were performed with controlled delays added to the display update and hand controller (joystick) signals. The added delays ranged from 0 to 30 ms for the display update, and from 0 to 800 ms for the hand controller. We found a strong effect on latency in the display update and a significant negative effect for 800 ms added delay on latency in the hand controller (in total approx. 880 ms latency including the system delay). The Simulator Sickness Questionnaire (SSQ) gave significantly higher scores after the experiment compared to before the experiment, but a majority of the participants reported experiencing only minor symptoms. Some test subjects ceased the test before finishing due to their symptoms, particularly due to the added latency in the display update.

    • In this study, we investigate a VR simulator of a forestry crane used for loading logs onto a truck, mainly looking at Quality of Experience (QoE) aspects that may be relevant for task completion, but also whether there are any discomfort related symptoms experienced during task execution. A QoE test has been designed to capture both the general subjective experience of using the simulator and to study task performance. Moreover, a specific focus has been to study the effects of latency on the subjective experience, with regards to delays in the crane control interface. A formal subjective study has been performed where we have added controlled delays to the hand controller (joystick) signals. The added delays ranged from 0 ms to 800 ms. We found no significant effects of delays on the task performance on any scales up to 200 ms. A significant negative effect was found for 800 ms added delay. The Symptoms reported in the Simulator Sickness Questionnaire (SSQ) was significantly higher for all the symptom groups, but a majority of the participants reported only slight symptoms. Two out of thirty test persons stopped the test before finishing due to their symptoms.

  • Joint effects of depth‑aiding augmentations and viewing positionson the quality of experience in augmented telepresence
  • 2020
  • In: Quality and User Experience. - Switzerland : Springer Nature. - 2366-0139 .- 2366-0147. ; 5
  • Journal article (peer-reviewed)abstract
    • Virtual and augmented reality is increasingly prevalent in industrial applications, such as remote control of industrial machinery,due to recent advances in head-mounted display technologies and low-latency communications via 5G. However, theinfluence of augmentations and camera placement-based viewing positions on operator performance in telepresence systemsremains unknown. In this paper, we investigate the joint effects of depth-aiding augmentations and viewing positionson the quality of experience for operators in augmented telepresence systems. A study was conducted with 27 non-expertparticipants using a real-time augmented telepresence system to perform a remote-controlled navigation and positioningtask, with varied depth-aiding augmentations and viewing positions. The resulting quality of experience was analyzed viaLikert opinion scales, task performance measurements, and simulator sickness evaluation. Results suggest that reducing thereliance on stereoscopic depth perception via camera placement has a significant benefit to operator performance and qualityof experience. Conversely, the depth-aiding augmentations can partly mitigate the negative effects of inferior viewingpositions. However the viewing-position based monoscopic and stereoscopic depth cues tend to dominate over cues basedon augmentations. There is also a discrepancy between the participants’ subjective opinions on augmentation helpfulness,and its observed effects on positioning task performance.

    • In this paper, we investigate how different viewing positions affect a user's Quality of Experience (QoE) and performance in an immersive telepresence system. A QoE experiment has been conducted with 27 participants to assess the general subjective experience and the performance of remotely operating a toy excavator. Two view positions have been tested, an overhead and a ground-level view, respectively, which encourage reliance on stereoscopic depth cues to different extents for accurate operation. Results demonstrate a significant difference between ground and overhead views: the ground view increased the perceived difficulty of the task, whereas the overhead view increased the perceived accomplishment as well as the objective performance of the task. The perceived helpfulness of the overhead view was also significant according to the participants.

    • A general equivalent-circuit-based method for the de-embedding of scattering parameters is presented. An equivalent circuit representation is used to model the embedding package. The parameters in the models are estimated with a statistical method using measured data from all de-embedding standards jointly together. Hence, it is possible to assess parameter estimates and their variance and covariance due to measurement uncertainties. A general de-embedding equation, which is valid for any five-port with a defined nodal admittance matrix, is derived and used in the subsequent de-embedding of measured device data. Different equivalent circuit models for the embedding network are then studied, and tradeoffs between model complexity and uncertainty are evaluated. Furthermore, the influence of varying number and combinations of de-embedding standards on the parameter estimates is investigated. The method is verified, using both measured and synthetic data, and compared against previously published work. It is found to be more general while keeping or improving accuracy.

  • Galectin 3 Aggravates Joint Inflammation and Destruction in Antigen-Induced Arthritis
  • 2011
  • In: ARTHRITIS AND RHEUMATISM. - : John Wiley and Sons, Ltd. - 0004-3591 .- 1529-0131. ; 63:2, s. 445-454
  • Journal article (peer-reviewed)abstract
    • Objective. Galectin 3, an endogenous beta galactoside-binding lectin, plays an important role in the modulation of immune responses. The finding that galectin 3 is present in the inflamed synovium in patients with rheumatoid arthritis suggests that the protein is associated with the pathogenesis of this disease. We undertook this study to investigate the influence of galectin 3 deficiency in a murine model of arthritis. Methods. Wild-type (WT) and galectin 3-deficient (galectin 3(-/-)) mice were subjected to antigen-induced arthritis (AIA) through immunization with methylated bovine serum albumin. The concentration of serum cytokines (interleukin-6 [IL-6] and tumor necrosis factor alpha [TNF alpha]) and antigen-specific antibodies was evaluated using a cytometric bead array platform and enzyme-linked immunosorbent assay (ELISA). Cellular IL-17 responses were examined by flow cytometry, ELISA, and enzyme-linked immunospot assay. Results. The joint inflammation and bone erosion of AIA were markedly suppressed in galectin 3(-/-) mice as compared with WT mice. The reduced arthritis in galectin 3(-/-) mice was accompanied by decreased levels of antigen-specific IgG and proinflammatory cytokines. The frequency of IL-17-producing cells in the spleen was reduced in galectin 3(-/-) mice as compared with WT mice. Exogenously added recombinant galectin 3 could partially restore the reduced arthritis and cytokines in galectin 3(-/-) mice. Conclusion. Our findings show that galectin 3 plays a pathogenic role in the development and progression of AIA and that the disease severity is accompanied by alterations of antigen-specific IgG levels, systemic levels of TNF alpha and IL-6, and frequency of IL-17-producing T cells. To our knowledge, this is the first report of in vivo evidence that galectin 3 plays a crucial role in the development of arthritis.

  • I kalla krigets spår : hot, våld och beskydd som kulturarv
  • 2023
  • Book (peer-reviewed)abstract
    • Det förflutna används ständigt för att ge mening åt nuet. I kalla krigets spår skildrar framväxten av ett nytt svenskt militärt kulturarv. Här visas hur minnen och lämningar från en tid fylld av rädsla och säkerhetspolitiska spänningar får nya innebörder när bunkrar och nedlagda militäranläggningar omvandlas till museer, lyxbostäder och spännande besöksmål.Genom fältbesök vid en rad militära kulturarvsplatser runt om i Sverige har författarna undersökt vilka miljöer, föremål och känslor som idag får representera kalla kriget. De visar hur dåtidens hemligheter, hotbilder och militärfordon både blir kittlande och fascinerande inslag i kulturarvet och förmedlar idéer om trygghet och beskydd.Här tas ett nytt grepp på kulturarvsfrågor genom att minnesskapande sätts i relation till säkerhetspolitik. Utifrån kritiska kulturarvsstudier och feministisk teori diskuteras den nationella gemenskapens gränser och vilken roll som genus och sexualitet har i berättelserna om hot och försvar.I en demokrati måste frågor om militärt våld alltid genomlysas och diskuteras. Med denna utgångspunkt granskas kulturarvets betydelse för förståelsen av hot och säkerhet. Boken uppmanar till reflektion om hur historien skrivs och om vad som krävs för att skapa trygghet.I kalla krigets spår är ett resultat av ett tvärvetenskapligt forskningsprojekt. Författarna är forskare vid Stockholms universitet och har skrivit boken tillsammans.

    • The control of activity and localization of transcription factors is critical for appropriate transcriptional responses. In eukaryotes, signal transduction components such as mitogen-activated protein kinase (MAPK) shuttle into the nucleus to activate transcription. It is not known in detail how different amounts of nuclear MAPK over time affect the transcriptional response. In the present study, we aimed to address this issue by studying the high osmolarity glycerol (HOG) system in Saccharomyces cerevisiae. We employed a conditional osmotic system, which changes the period of the MAPK Hog1 signal independent of the initial stress level. We determined the dynamics of the Hog1 nuclear localization and cell volume by single-cell analysis in well-controlled microfluidics systems and compared the responses with the global transcriptional output of cell populations. We discovered that the onset of the initial transcriptional response correlates with the potential of cells for rapid adaptation; cells that are capable of recovering quickly initiate the transcriptional responses immediately, whereas cells that require longer time to adapt also respond later. This is reflected by Hog1 nuclear localization, Hog1 promoter association and the transcriptional response, but not Hog1 phosphorylation, suggesting that a presently uncharacterized rapid adaptive mechanism precedes the Hog1 nuclear response. Furthermore, we found that the period of Hog1 nuclear residence affects the amplitude of the transcriptional response rather than the spectrum of responsive genes.

    • Complex metal hydrides are a fascinating and continuously expanding class of materials with many properties relevant for solid-state hydrogen and ammonia storage and solid-state electrolytes. The crystal structures are often investigated using powder X-ray diffraction (PXD), which can be ambiguous. Here, we revisit the crystal structure of Y(11BD4)3·3ND3 with the use of neutron diffraction, which, in comparison to previous PXD studies, provides accurate information about the D positions in the compound. Upon cooling to 10 K, the compound underwent a polymorphic transition, and a new monoclinic low-temperature polymorph denoted as α-Y(11BD4)3·3ND3 was discovered. Furthermore, the series of Y(11BH4)3·xNH3 (x = 0, 3, and 7) were also investigated with inelastic neutron scattering and infrared spectroscopy techniques, which provided information of the local coordination environment of the 11BH4- and NH3 groups and unique insights into the hydrogen dynamics. Partial deuteration using ND3 in Y(11BH4)3·xND3 (x = 3 and 7) allowed for an unambiguous assignment of the vibrational bands corresponding to the NH3 and 11BH4- in Y(11BH4)3·xNH3, due to the much larger neutron scattering cross section of H compared to D. The vibrational spectra of Y(11BH4)3·xNH3 could roughly be divided into three regions: (i) below 55 meV, containing mainly 11BH4- librational motions, (ii) 55-130 meV, containing mainly NH3 librational motions, and (iii) above 130 meV, containing 11B-H and N-H bending and stretching motions.

  • Conference paper (peer-reviewed)abstract
    • A growing trend in science is that research institutions reach out to members of the public for participating in research. The reasons for outreach are many, spanning from the desire to collect and/or analyse large sets of data efficiently, to the idea of including the general public on a very fundamental level in science-making and ultimately decision-making. The presented project is curriculum-based and carried out in 240 lower secondary school classes (pupils of age 13-16). The task, as designed by the participating universities, is to collect mushrooms, soil and animal droppings from different parts of Sweden, do preliminary sample preparation and analyses and send the samples to the university institutions for radioactivity measurement. Behind the project is a desire to compare today’s levels of 137Cs with those deposited right after the Chernobyl accident in 1986, but also to study the exchange of caesium between organisms as well as the impacts of biological and geological processes on uptake and retention. The scientific outcome is a geodatabase with the 137Cs activity (Bq/m2) present in the Swedish environment, where radioactivity data can be linked to the species (fungi, competing species, animals foraging), forest type, land type, land use and other environmental factors. The science question is of interest to the general public as foraging for mushrooms, as well as spending recreational time in forests is widely popular in Sweden. In this article, we will discuss the current status of the project and the observations we have made about how well the public can participate in scientific research. Focus will be on organization of the project, such as logistics, preparation of supportive material, feedback and communication between researchers and schools. We will present observations about the impact the project has had on the participants, based on quantitative and qualitative evaluations.

    • The paper describes a validation model for both subjective and objective comparison of on-the-limit properties of a driving simulator. VTI moving base driving simulator, SIM III, has been used with three different versions of VTI’s vehicle model, for validation toward field tests involving double lane change manoeuvres. Methods for handling evaluation suggested in the literature were adapted to our circumstances. The results are encouraging, although we found some limitations with respect to the objective evaluations that need to be addressed in future studies.

  • Driver reactions to horn and headlight warnings in critical situations : A simulator study
  • 2013
  • In: Proceedings of the 16th International Conference Road Safety on Four Continents. - Linköping : Statens väg- och transportforskningsinstitut.
  • Conference paper (other academic/artistic)abstract
    • This paper presents a driving simulator study on driving behavior in a critical head-on collision scenario. The study aims at providing basic understanding of driver responses to headlight and horn warning coming from another vehicle a time critical situation. In total, 48 participants drove 30 km. During the drive participants performed a secondary task, announced by a vibration in the seat. At the time of the secondary task the own vehicle was directed into the opposing lane where oncoming simulated vehicles issued a light and/or sound warnings to get the drivers attention. An additional purpose of the study was to examine if the warning coming from the other vehicle has a different effect on persons with a hearing loss. A possible application for this type of warnings is the implementation of a system for automatic activation. Systems for automatic activation of brakes and steering are currently entering the market. These systems use proximity sensors to monitor the state of surrounding road users. Depending on the specific situation the effort/possibility to avoid or mitigate an accident may differ significantly between the principle road users of a pending collision, e.g. one road user (1) may easily avoid a collision while another (2) may not be able to do so. The only possibility for the second road user (2) to avoid a collision in such a situation is to issue a warning to the first (1), so that he/she may take evasive actions. Connecting the horn and the headlight to already existing sensor system, for automatic warning activation, is a cost effective means to provide such a warning. The warnings, could of course, also be triggered manually by the driver.The results indicate that a driver who receives a warning from the oncoming vehicle responds faster to avoid the pending frontal collision. The most effective warning was the combination of horn and headlight. A majority of the participants where positive to the notion of an automated system to provide this type of warning (n=41). No significant difference in the behavior between the groups with and without hearing loss was found in this study.

    • Avhandlingen behandlar de teoretiska och praktiska aspekterna av att använda spektrala vinkelupplösta reflektansmätningar för optisk karakterisering av fiberbaserade material såsom papper och kartong. En spektral goniofotometer används för att mäta det reflekterade ljusets vinkelfördelning. En stor del av arbetet utgörs av att utvärdera instrumentets noggrannhet, samt utreda hur de vinkelupplösta mätningarna skall utföras på bästa sätt för att erhålla en så fullständig karakterisering som möjligt. Det reflekterade ljuset består av tre komponenter; ytreflektans, bulkreflektans samt fluorescens. En fullständig karakterisering förutsätter att dessa tre komponenter kan analyseras separat, vilket i detta arbete görs genom nyutvecklade metoder.En metod har utvecklats för separation av ytreflektans och bulkreflektans. Metoden bygger på att analysera hur den totala reflektansen förändras vid ökande absorption i det reflekterande materialet. Absorptionen kontrolleras genom inkjet-tryckning där tryckfärg appliceras på substratet i sådan mängd att bulkreflektansen helt släcks ut. Genom att kombinera mätningar på tryckt och otryckt substrat kan de båda komponenterna separeras. Trots att ytreflektansen från ett matt papper är liten i förhållande till bulkreflektansen, så visar resultaten att den ökar markant med ökande betraktningsvinkel och kan därmed ha stor inverkan på den totala reflektansen. Bidraget från fluorescens kan kvantitativt analyseras genom att kombinera mätningar utförda med respektive utan UV-filter. Vinkelupplösta mätningar och Monte Carlo-simuleringar av fluorescensens vinkelfördelning visar att dess anisotropi är relaterad till det medeldjup vid vilket fluorescensen emitteras. Resultaten förklarar observerade skillnader och motstridigheter i tidigare rapporterade studier kring huruvida fluorescens kan anses vara Lamberskt fördelad.Samtliga goniofotometriska mätningar är utförda med ett kompakt, kommersiellt tillgängligt, dubbelstråleinstrument. För att undersöka instrumentets lämplighet för absoluta reflektansmätningar utförs en analys av dess mätnoggrannhet. Resultaten visar att instrumentets kompakta storlek i kombination med den anisotropa reflektansen från papper introducerar systematiska fel av samma storleksordning som den totala mätnoggrannheten. Dessa fel uppstår på grund av den relativt stora detektorapertur som måste användas vid mätningar av diffus reflektans, vilket är karakteristiskt för papper och kartong. Resultaten visar även att felen är störst vid flacka mätvinklar och för prover med hög grad av anisotropisk reflektans, och en geometrisk korrektionsmetod för denna typ av systematiska fel föreslås.Spektrala och vinkelupplösta mätningar medför per automatik stora mängder mätdata. Genom att använda strålningstransportteori som en matematisk modell för hur ljus sprids i papper kan mätdatat reduceras till en uppsättning beskrivande materialparameterar. Att uppskatta dessa optiska parametrar utifrån vinkelupplösta reflektansmätningar är i sig ett komplicerat problem, vilket dessutom är känsligt för mätfel och val av mätvinklar. Detta inversa problem analyseras i detalj, och speciellt hur valet av mätvinklar kan reduceras utan att försämra förutsättningarna för estimeringen. Simuleringar visar att mätningarna kan begränsas till infallsplanet, eller till och med enbart framåtriktningen, så länge tillräckligt flacka mätvinklar är inkluderade i mätsekvensen.

  • As above, so below? : On AHD critique, identity, essence and Cold War heritagizations in Sweden
  • 2023
  • In: Journal of War & Culture Studies. - : Taylor & Francis. - 1752-6272 .- 1752-6280. ; 16:4, s. 373-392
  • Journal article (peer-reviewed)abstract
    • In this article, the example of Cold War heritagizations in a Swedish context is utilized to reflect on conceptualizations of heritage regarding identity and authenticity within critical heritage studies and research on Authorized Heritage Discourse (AHD). Herein, heritage is perceived as a difference machinery in which difference-produced identities are enacted and performed, and a Deleuzian and Butleresque antiessentialist perspective is adopted to show how the illusion of actual, nondifferential identities is underpinned by a hypostasized reification of AHD. Based on the analysis of how gender has been actualized within official and informal heritagizations, the central discussion concerns the purported benefits of heritages and heritagizations from below, often articulated within critical heritage studies literature. It is argued that both official and informal Cold War heritagizations construct a naturalized gendered logic of protection, with the consequence that security policy issues regarding protection and military violence are placed in a nonnegotiable, extrapolitical sphere.

  • Digital transformation in schools of two southern regions of Sweden through implementation-informed approach : A mixed-methods study protocol
  • 2023
  • In: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 18:12
  • Journal article (peer-reviewed)abstract
    • Background: The enhancement of–or even a shift from–traditional teaching and learning processes to corresponding digital practices has been rapidly occurring during the last two decades. The evidence of this ongoing change is still modest or even weak. However, the adaptation of implementation science in educational settings, a research approach which arose in the healthcare field, offers promising results for systematic and sustained improvements in schools. The aim of this study is to understand how the systematic professional development of teachers and schools principals (the intervention) to use digital learning materials and learning analytics dashboards (the innovations) could allow for innovative and lasting impacts in terms of a sustained implementation strategy, improved teaching practices and student outcomes, as well as evidence-based design of digital learning material and learning analytics dashboards.Methods: This longitudinal study uses a quasi-experimental cluster design with schools as the unit. The researchers will enroll gradually 145 experimental schools in the study. In the experimental schools the research team will form a School Team, consisting of teachers/learning-technologists, school principals, and researchers, to support teachers’ use of the innovations, with student achievement as the dependent variable. For the experimental schools, the intervention is based on the four longitudinal stages comprising the Active Implementation Framework. With an anticipated student sample of about 13,000 students in grades 1–9, student outcomes data are going to be analyzed using hierarchical linear models.Discussion: The project seeks to address a pronounced need for favorable conditions for children’s learning supported by a specific implementation framework targeting teachers, and to contribute with knowledge about the promotion of improved teaching practices and student outcomes. The project will build capacity using implementation of educational technology in Swedish educational settings.

  • Prospects and problems of transferring quality-improvement methods from health care to social services : two case studies
  • 2014
  • In: The Permanente Journal. - 1552-5767 .- 1552-5775. ; 18:2, s. 38-42
  • Journal article (peer-reviewed)abstract
    • INTRODUCTION:This study examines the use of quality-improvement (QI) methods in social services. Particularly the key aspects-generalizable knowledge, interprofessional teamwork, and measurements-are studied in projects from the QI program Forum for Values in Sweden.METHODS:This is a mixed-method case study. Two projects using standard QI methods and tools as used in health care were chosen as critical cases to highlight some problems and prospects with the use of QI in social services. The cases were analyzed through documented results and qualitative interviews with participants one year after the QI projects ended.RESULTS:The social service QI projects led to measurable improvements when they used standard methods and tools for QI in health care. One year after the projects, the improvements were either not continuously measured or not reported in any infrastructure for measurements. The study reveals that social services differ from health care regarding the availability and use of evidence, the role of professional expertise, and infrastructure for measurements.CONCLUSIONS:We argue that QI methods as used in health care are applicable in social services and can lead to measurable improvements. The study gives valuable insights for QI, not only in social services but also in health care, on how to assess and sustain improvements when infrastructures for measurements are lacking. In addition, when one forms QI teams, the focus should be on functions instead of professions, and QI methods can be used to support implementation of evidence-based practice.

  • Colour Gamuts - Is size the only thing that matters?
  • 2006
  • In: Proceedings of the Technical Association of the Graphic Arts, TAGA. ; , s. 273-281
  • Conference paper (peer-reviewed)abstract
    • Today's Inkjet printers are capable of producing colour images of very high quality. However, in inkjet printing, the substrate has a large influence on the quality of a printed image. In addition, the large variety of inkjet substrates increases the complexity of the colour reproduction in inkjet printers. Even when high-quality substrates are used, colour management is required when the input data is represented in any of the RGB colour spaces used today. Moreover, colour gamut transformations are inherent as the colour gamut of colour reproduction systems differ in size and shape. In this study, three colour rendering attributes associated with image quality - colour gradation, colour gamut volume and sharpness have been varied prior to printing in a set of test images. In real life, variations in these colour rendition attributes can be caused by different substrate properties, inappropriate printer settings for a specific substrate or the result of shortcomings in colour management. Whatever the cause may be, the effects of these variations can be observed in inkjet-printed images. The colour gamut volume, colour gradation and sharpness were varied simultaneously according to a statistical experimental design thus producing a subset of modified versions for each image in the test set. Furthermore, a visual assessment study was carried out in order to study the effect of the modifications on the perceived impression of the colour rendition in the printed images. Finally, the data from the visual assessment study was analysed in order to reveal how the different attributes influenced the perceived colour rendition.

  • Piloting Systematic Implementation of Educational Technology in Swedish K-12 Schools : Two-Years-In Report
  • 2024
  • In: Global Implementation Research and Applications. - : Springer.
  • Journal article (peer-reviewed)abstract
    • Halfway through a four-year research project supported by implementation science and the Active Implementation Frameworks (AIF), this article reports on the status of the initial two implementation stages. Our research investigates the impact of systematically preparing educators and educational institutions to integrate digital learning materials and learning analytics dashboards to enrich teaching practices and improve student performance outcomes.Furthermore, it seeks to establish a foundation for the use of innovative and validated educational technology (EdTech) through sustainable implementation strategies, evidence-based evaluation, and continuous redesign of digital learning materials. By adopting this comprehensive approach, we aim to enhance the knowledge base regarding effective digital innovation integration within educational environments.We argue that applying implementation science in educational settings facilitates the adoption of effective innovations, promotes evidence-based decision-making, and helps identify and address obstacles to change. Our ongoing research underscores the transformative impact of implementation science in education. Thus far, we have highlighted the crucial role of teacher perspectives and the necessity of co-designing technology aligned with teaching and learning objectives.This nuanced approach refutes the notion of a one-size-fits-all solution or a quick fix achievable in a single academic year. Instead, it advocates a dynamic, collaborative model that acknowledges the multifaceted nature of implementation. Our journey has reaffirmed the dedication of teachers, showcasing their readiness to invest time and effort when their professionalism is respected, and their input is genuinely valued and acted upon.

  • Interactions of N2O5 and Related Nitrogen Oxides with Ice Surfaces: Desorption Kinetics and Collision Dynamics
  • 2014
  • In: Journal of Physical Chemistry B. - : American Chemical Society (ACS). - 1520-6106 .- 1520-5207. ; 118:47, s. 13427-13434
  • Journal article (peer-reviewed)abstract
    • The detailed interactions of nitrogen oxides with ice are of fundamental interest and relevance for chemistry in cold regions of the atmosphere. Here, the interactions of NO, NO2, N2O4, and N2O5 with ice surfaces at temperatures between 93 and 180 K are investigated with molecular beam techniques. Surface collisions are observed to result in efficient transfer of kinetic energy and trapping of molecules on the ice surfaces. NO and NO2 rapidly desorb from pure ice with upper bounds for the surface binding energies of 0.16 +/- 0.02 and 0.26 +/- 0.03 eV, respectively. Above 150 K, N2O4 desorption follows first-order kinetics and is well described by the Arrhenius parameters E-a = 0.39 +/- 0.04 eV and A = 10((15.41.2)) s(1), while a stable N2O4 adlayer is formed at lower temperatures. A fraction of incoming N2O5 reacts to form HNO3 on the ice surface. The N2O5 desorption rates are substantially lower on pure water ice (Arrhenius parameters: Ea = 0.36 +/- 0.02 eV; A = 10(15.3 +/- 0.7) s(-1)) than on HNO3-covered ice (Ea = 0.24 +/- 0.02 eV; A = 10(11.5 +/- 0.7) s(-1)). The N2O5 desorption kinetics also sensitively depend on the sub-monolayer coverage of HNO3, with a minimum in N2O5 desorption rate at a low but finite coverage of HNO3. The studies show that none of the systems with resolvable desorption kinetics undergo ordinary desorption from ice, and instead desorption likely involves two or more surface states, with additional complexity added by coadsorbed molecules.

  • Decision Support for Emergency Response to Multiple Natural Hazards : CHALLENGES AND NEEDS
  • 2022
  • Licentiate thesis (other academic/artistic)abstract
    • Global warming exceeding 1.5°C above pre-industrial levels will very likely lead to unavoidable increases of several climate hazards in the coming decades. Climate change phenomena can increase the risk of several extreme weather events, leading to risks of what is commonly considered as natural hazards, for instance landslides and forest fires. These chains or networks of events are termed natural multi-hazards or compound natural events, referring to a primary event or a driver that directly triggers or increases the probability of one or more secondary events by changing the environment. The very likely increase of single and compound natural hazards due to climate change require increased attention since it may imply new challenges to emergency response systems and new threats to society. Especially, how emergency response systems can prepare for and respond to these hazards by using knowledge of the interactions between different natural events.   The purpose of this thesis is to increase the knowledge on interactions between natural hazards, investigate how multiple natural hazards lead to challenges for emergency response systems, and how these challenges can be addressed. The purpose can be further divided into three objectives: (i) to identify relevant multiple natural hazards in a Swedish context, (ii) to identify planning and decision-making challenges these hazards may imply for emergency response systems, and (iii) to develop a decision support tool addressing one of these challenges.  The objectives have been addressed in three sub-studies, one for each of the objectives, leading to the production of four papers. The first sub-study focused on the first objective and resulted in the construction of a national natural hazard interaction framework for Sweden, which is presented in Paper 1. The second sub-study focused on the second objective, leading to the identification of needs for information, planning, and decision support systems in the Swedish emergency response system. The results from this study are presented in Paper 2 and 3. The third and last sub-study focused on the development of a decision support tool addressing one of the needs identified in the second sub-study. The sub-study led to the development of an optimization model for resource preparedness location planning, presented in Paper 4.  This thesis contributes to the emergency management field, both scientifically and practically. The scientific contributions are the development of a national natural hazard interactions framework and a resource preparedness location model for wildfires, both filling gaps in the current knowledge. Also, the thesis contributes scientifically through the alternative applications of theory, which can inform the research community in future studies. The natural hazard interaction framework and the resource preparedness location model for wildfires are also considered practical contributions. The former can support the extension of regional and local risk and vulnerability analyses to also include multiple natural hazards, while the latter sheds light on the potential of optimization-based decision support tools to increase preparedness to natural hazards.
