    Modeling of Ce2, Ce2O3 ,and CeO2-x in the LDA+U formalism2007Inngår i: Physical Review B Condensed Matter, ISSN 0163-1829, E-ISSN 1095-3795, Vol. 75, nr 3, s. 035109-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [sv]

    The electronic structure and thermodynamic properties of CeO2 and Ce2O3 have been studied from first principles by the all-electron projector-augmented-wave (PAW) method, as implemented in the ab initio total-energy and molecular-dynamics program VASP (Vienna ab initio simulation package). The local density approximation (LDA)+U formalism has been used to account for the strong on-site Coulomb repulsion among the localized Ce 4f electrons. We discuss how the properties of CeO2 and Ce2O3 are affected by the choice of U as well as the choice of exchange-correlation potential, i.e., the local density approximation or the generalized gradient approximation. Further, reduction of CeO2, leading to formation of Ce2O3 and CeO2-x, and its dependence on U and exchange-correlation potential have been studied in detail. Our results show that by choosing an appropriate U it is possible to consistently describe structural, thermodynamic, and electronic properties of CeO2, Ce2O3, and CeO2-x, which enables modeling of redox processes involving ceria-based materials.

    Redox properties of CeO2-MO2 MO2 (M=Ti, Zr, Hf or Th) solid solutions from first principles calculations2007Inngår i: Applied Physics Letters, ISSN 0003-6951, E-ISSN 1077-3118, Vol. 90, nr 3, s. 031909-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The authors have used density functional theory calculations to investigate how the redox thermodynamics and kinetics of CeO2 are influenced by forming solid solutions with TiO2, ZrO2, HfO2, and ThO2. Reduction is facilitated by dissolving TiO2 (largest improvement), HfO2, or ZrO2 (least improvement), while ThO2 makes reduction slightly more difficult. The migration barrier is much lower in the neighborhood of a Ti (largest decrease), Hf, or Zr (least decrease), while the binding energy of solute ions and vacancies increases in the same sequence. They rationalize the properties of ceria solid solutions in terms of defect cluster relaxations.

    Theoretical study of CeO(2) doped with tetravalent ions2007Inngår i: Physical Review B Condensed Matter, ISSN 0163-1829, E-ISSN 1095-3795, Vol. 76, nr 7, s. 174119-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We have used density functional theory calculations within the LDA+U formulation to investigate how small amounts of dissolved SiO2, GeO2, SnO2, or PbO2 affect the redox thermodynamics of ceria (CeO2). Compared to pure ceria, reduction is facilitated and the reducibility increases in the sequence of CeO2-SnO2, CeO2-GeO2, and CeO2-SiO2, which correlates with the decrease of the ionic radii of the solutes. For low solute concentrations, there is an inverse relation between high reducibility and the solution energy of tetravalent solutes. CeO2-PbO2 is unique in the sense that the initial reduction occurs by Pb(IV)double right arrow Pb(II) instead of the usual Ce(IV)double right arrow Ce(III) reaction. Among the investigated ceria compounds, CeO2-PbO2 has the lowest reduction energy and rather low solution energy. We have studied how the solution and reduction energies depend on the concentration of Si, Ge, Sn, Pb, Ti, Zr, Hf, and Th solute ions. While the solution energy increases monotonously with concentration, the reduction energy first decreases, as compared to pure ceria (except for Th, which exhibits a small increase), and with further increase of solute concentration, it either remains almost constant (Zr, Hf, and Th) or slightly increases (Ti, Si, Ge, and Sn).

    Optimization of ionic conductivity in doped ceria2006Inngår i: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 103, nr 10, s. 3518-3521Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Oxides with the cubic fluorite structure, e.g., ceria (CeO2), are known to be good solid electrolytes when they are doped with cations of lower valence than the host cations. The high ionic conductivity of doped ceria makes it an attractive electrolyte for solid oxide fuel cells, whose prospects as an environmentally friendly power source are very promising. In these electrolytes, the current is carried by oxygen ions that are transported by oxygen vacancies, present to compensate for the lower charge of the dopant cations. Ionic conductivity in ceria is closely related to oxygen-vacancy formation and migration properties. A clear physical picture of the connection between the choice of a dopant and the improvement of ionic conductivity in ceria is still lacking. Here we present a quantum-mechanical first-principles study of the influence of different trivalent impurities on these properties. Our results reveal a remarkable correspondence between vacancy properties at the atomic level and the macroscopic ionic conductivity. The key parameters comprise migration barriers for bulk diffusion and vacancy-dopant interactions, represented by association (binding) energies of vacancy-dopant clusters. The interactions can be divided into repulsive elastic and attractive electronic parts. In the optimal electrolyte, these parts should balance. This finding offers a simple and clear way to narrow the search for superior dopants and combinations of dopants. The ideal dopant should have an effective atomic number between 61 (Pm) and 62 (Sm), and we elaborate that combinations of Nd/Sm and Pr/Gd show enhanced ionic conductivity, as compared with that for each element separately.

    Abstract [en]

    This thesis is a comparative study of Rapid Serial Visual Presentation (RSVP) which is a

    dynamic method of presenting text.

    The aim of the study was to investigate how to improve the user friendlyness of RSVP for

    today's mobile phones and technology. To fulfill the purpose, the aspects of the method which

    could be improved was investigated and then implemented in a prototype. The prototype was

    tested in an experimental study after which the result was analyzed and compared with previous

    studies of RSVP.

    The new features that were implemented in this study showed no significant improvements in

    usability compared with previous studies, but proved to be more user-friendly in comparison

    with normal spatial reading.

    Systematisk kunskapsbrist i skolan?: Arbetsmiljöarbete utan udd2014Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Det är lagstadgat att arbetsgivaren är skyldig att bedriva ett systematiskt arbetsmiljöarbete (SAM) för att sänka riskerna för ohälsa och olycksfall i verksamheten. Mycket tyder på att detta inte fungerar tillfredställande i många skolor. Denna fallstudie syftar till att kartlägga och synliggöra hur det systematiska arbetsmiljöarbetet organiserats i två utvalda kommunala grundskolor.

     

    Det övergripande syftet i studien var att belysa faktorer och mekanismer som kan motverka ett lyckat införande av ett fungerande arbetsmiljöarbete. De frågeställningar vi haft var om kommunernas organisering av arbetsmiljöarbetet uppfyller lagstiftningens krav och hur uppföljningen och kontrollen sker. Studien har genomförts genom analys av kommunernas styrdokument samt genom en enkät kombinerad med uppföljande intervjuer av nyckelpersoner i verksamheterna.

     

    Resultat visar att de båda grundskolornas arbetsmiljöarbete organiserats och bedrivs på ett likartat sätt och att arbetsmiljöproblemen till stor del är likartade. Bilden är samstämmig från de båda verksamheterna att organiseringen inte förmår att fånga upp och hantera alla betydande risker. Slutsatserna från studien är att det finns bristande arbetsmiljökunskap hos alla aktörer som har uppgifter i arbetsmiljöarbetet.

    Det passar inte alla: Arbetstillfredställelse, produktivitet och stress i kontorslandskap2016Independent thesis Advanced level (degree of Master (One Year)), 40 poäng / 60 hpOppgave
    Abstract [sv]

    Kontorslandskapen på Stora kontoret i Boliden har renoverats. Efter renoveringen ville företaget ha en utvärdering av vad personalen tyckte om den fysiska arbetsmiljön. Företaget ville även få fram förbättringsförslag för brister kopplat till den fysiska arbetsmiljön.

     

    Syftet med den här studien var att identifiera positiva och negativa aspekter för de fysiska arbetsmiljöfaktorerna, samt att identifiera eventuella samband mellan de faktorer som personalen var mest missnöjd över och arbetstillfredsställelse, produktivitet och stress. Ett andra syfte var att ta fram några åtgärdsförslag. En del i frågeställningen var om det fanns könsskillnader i hur personalen skattade de fysiska arbetsmiljöfaktorerna. Studien genomfördes med enkät samt systemgruppsseminarium som metod.

     

    Personalen var generellt nöjd med ventilation, möblernas funktion och kontorets estetiska utformning. Audiell avskildhet var den faktor som personalen var mest missnöjd med. Även missnöjdhet över bländning, utblicksmöjlighet och temperatur uppmärksammades i resultatet. Den här studien fann inga signifikanta könsskillnader för hur personalen skattat de fysiska arbetsmiljöfaktorerna.

     

    Tidigare studier har visat att det finns samband mellan fysiska arbetsmiljöfaktorer och arbetstillfredsställelse samt produktivitet, men inte ett entydigt resultat för stress. Den här studien stärkte sambandet för hur nöjd personalen var med audiell avskildhet och dess samverkan med arbetstillfredsställelse och produktivitet, men inte med stress.

     

    De förbättringsförslag som togs fram av systemgruppsseminariet var att införa riktlinjer för hur personalen skulle kunna minska störningen från ljud i kontorslandskapen, samt att avskilja avdelningarna mer. Rekommendation till Boliden blir att de bör förbättra den audiella avskildheten genom en kombination av åtgärder. De kan omplacera personal i kontorslandskapet baserat på arbetsuppgifter och känslighet för störning, förbättra avskiljningen mellan arbetsgrupper samt införa riktlinjer för hur personalen åstadkommer en god ljudmiljö.

    Simuleringsbaserad analys av pendelbåtstrafik i Stockholm2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    This paper analyzes how an agent-based simulation model of Stockholm can be used for water transitplanning. A new route for commuters by boat was added to the model of Stockholm’s existingtransport system and evaluated. By comparing results from the model and statistic data fromTrafikförvaltningen Region Stockholm during the morning rush-hour, a scale factor was calculated.The scale factor was later used to adjust the number of travelers on the added new water transit routeas the model underestimate the number of persons who use the available public transport by boat. Thelarge size of the calculated factor made the results uncertain when trying to predict any effects the newroute would have, e.g. on congestion in the system. Simulations of the new transit line resulted in amajority of short trips, between stations were the other public transit options took longer routes. Thetransit stops close to the city centre were used the most and most trips were conducted between them.To gain an improved ability to simulate water transit, continued studies of people’s preferencesregarding mode choice appear to be crucial.

    Fibrillar structure of resorbable microblock copolymers based on 1,5-dioxepan-2-one and epsilon-caprolactone2003Inngår i: Journal of Polymer Science Part A: Polymer Chemistry, ISSN 0887-624X, E-ISSN 1099-0518, Vol. 41, nr 15, s. 2412-2423Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The copolymerization of 1,5-dioxepan-2-one (DXO) and E-caprolactone, initiated by a five-membered cyclic tin alkoxide initiator, was performed in chloroform at 60 degreesC. Copolymers with different molar ratios of DXO (25, 40, and 60%) were synthesized and characterized. C-13 NMR spectroscopy of the carbonyl region revealed the formation of copolymers with a blocklike structure. Differential scanning calorimetry measurements showed that all the copolymers had a single glass transition between -57 and -49 degreesC and a melting temperature in the range of 30.1-47.7 degreesC, both of which were correlated with the amount of DXO. An increase in the amount of DXO led to an increase in the glass-transition temperature and to a decrease in the melting temperature. Dynamic mechanical thermal analysis measurements confirmed the results of the calorimetric analysis, showing a single sharp drop in the storage modulus in the temperature region corresponding to the glass transition. Tensile testing demonstrated good mechanical properties with a tensile strength of 27-39 MPa and an elongation at break of up to 1400%. The morphology of the copolymers was examined with polarized optical microscopy and atomic force microscopy; the films that crystallized from the melt showed a short fibrillar structure (with a length of 0.05-0.4 mum) in contrast to the untreated solution-cast films.

    A Generative Design of TimberStructures According to Eurocode: Development of a Parametric Model in Grasshopper2019Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The interest of timber structures has in recent years increased, primarily due tothe environmental benets of timber. This has created an increased demand forstructural engineers with timber expertise. At the same time the concept of structuralparametric design have become more popular. This new way of working withdesigns enables for architects and engineers to explore dierent geometries in earlystages of a project. However, the combination of a parametric workow and timberdesign have so far been limited due to the complexity of the material.This thesis aims to create an parametric workow within the visual programmingenvironment Grasshopper. This enables analysis of structural design simultaneouslywith a cross sectional and topological optimization of timber structures. The structuralanalysis is performed with Karamba which is a plug-in tool to the Grasshopperenvironment. The design verication based on Eurocode EN-1995 have been manuallyscripted in python components. The parametric model have been applied to acase where the main bearing bearing of a glass roof is to be designed. Three dierentgeometries have been evaluated with regard to cross sectional dimensions andgeometrical shape.The framework with a truss turned out to be a preferable design if only consideringweight, deection and utilization. The truss frame provides the lowest weight and thesecond smallest displacement. Furthermore, a comparison of the structural analysisand design have been performed with the FEM-program Robot. The compassionshow similar results, increasing the reliability of the Grasshopper model and theresults from this tool. It conrms it is possible to perform generative design oftimber structures within the same interface.The Grasshopper model is limited and can not handle all variations of 2D timberstructures. The complexity and variation of such calculations in conjunction with theEurocode have not been implemented during the time-span of this thesis. However,it is general within the limitations of the case study meaning a variety of framegeometries can be evaluated.

    Working with Time Management in IT Consulting: Developing a Time Management Strategy by Using Performance Management2013Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Time is in control of our everyday life and work life. Time is a valuable resource of which everyone possesses the same amount. In work life, time is important; it rules the workday and the tasks that are being performed. Time is even more significant within the consultancy industry, where worked time and competence is what is being delivered to the customers. Since time is of great importance for consulting firms, time management systems and time reporting become a crucial part of a consultant’s day. IT consulting firms spend lots of time and money on business systems, despite this the area of how time management and performance management are connected is relatively unexplored.

    This report aims to contribute to an enhanced understanding regarding why consultancy firms work with time management, and how data from time management systems could be used. The study will also investigate how the employees could be motivated to use the time management system in the extent that the managers wish, as well as important requirements on data from the time management system. These questions can together give answer to how time management can be aligned with performance management within an IT consultancy firm.

    The report is based on 14 interviews performed at five different IT consulting firms in the Stockholm area, a participant observation conducted at one of the participating companies, as well as a literature review. The study was performed during the spring of 2013.

    The study found that the main reason for IT consultant firms to report time is to gain decision support for invoices and salary payments. Being able to see overtime and flextime is something that is appreciated by the employees. Other identified areas of usage are forecasts and estimates, evaluations and follow-ups, utilization rate calculations, and employee care. Regular follow-ups, preferable weekly, are necessary for motivating the employees to work with time management. It is also important that the time management system is easy to use in order for it to generate relevant decision support.

    The study shows that to implement a successful time management strategy, the following aspects should be considered: (i) to not measure too much, (ii) to have clear communication and weekly deadlines, (iii) to make it simple, (iv) to create awareness among the employees, and (v) to have a time management system that mutually benefits the managers and the employees.

    The Autonomous Vehicle: End of the Road, or the Beginning of A New Era?: Concept and Challenges of a Disruptive Innovation within the Automotive Industry2016Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [en]

    The Autonomous Vehicle is about to enter the mass-market. The question is not about when it will happen but in which conditions, under which form or who will be the first car manufacturer to release an efficient and reliable final product.By now, the equation has not been solved, due to the high price of the technologies needed, the lack of solutions to provide a reliable network, and the necessity to change conventions established a long time ago in terms of responsibility of the driver.Depending on who is talking, the Autonomous vehicle is not only an evolution of a previous product, which is able to evaluate and to progressively transform into something different that we could call a self-driven car. This innovation is one step further and is challenging everything that was established until now in terms of objective criteria expected from a car. This is why some are calling this a disruptive innovation, or even a revolution, in the sense that it has the power to totally change the way we are interacting with our everyday transportation system.To enter into the market, this technology, this product, will have to overcome some challenges, on the technological side but also on the psychological side of his future clients.Therefore, this thesis research analyses why this innovation could be the future of the Automotive industry, where it is coming from, what are the challenges it will have to overcome, which will be the impacts, and the different possible scenarios.

    Modelling of EMC screens for radio base stations Part 1: Experimental parametric study2004Inngår i: ITherm 2004, Vol 1, IEEE , 2004, s. 463-470Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Enclosing electronics in sealed metal boxes provides good electromagnetic shielding, but evidently restricts the air movement necessary for adequate cooling. In order to meet ElectroMagnetic Compatibility (EMC) requirements, a perforated plate (an EMC screen) must be used. The design of this screen must provide a sufficient free area ratio for the adequate airflow, but at the same time the holes must be small enough to block electromagnetic radiation. An experimental set-up that represents a Radio Base Station (RBS) subrack was built inside a wind tunnel. The airflow pattern and pressure drop through the EMC screen were investigated experimentally for different subrack geometries, screen porosities and velocities, and the recirculation zones were identified. The study was performed by means of pressure and velocity measurements, together with smoke visualization under isothermal conditions.

    Evaluation of diversion strategies using dynamic traffic assignment2011Inngår i: Transportation planning and technology (Print), ISSN 0308-1060, E-ISSN 1029-0354, Vol. 34, nr 3, s. 199-216Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A framework for the evaluation of the effectiveness of traffic diversion strategies for non-recurrent congestion, based on predictive guidance and using dynamic traffic assignment, is presented. Predictive guidance is based on a short-term prediction of traffic conditions, incorporating user reaction to information and guidance. A case study of the Lower Westchester County network in New York State, using DynaMIT-P, is presented to illustrate the application of the framework. DynaMIT-P is capable of evaluating diversion strategies based on predicted conditions, which take into account drivers' response to traffic information. The case study simulates the operations of predictive variable message signs positioned in strategic locations. DynaMIT-P is calibrated for the study network and used to establish base conditions for two incident scenarios in the absence of advanced traveller information systems. The effectiveness of predictive diversion strategies is evaluated (using rigorous statistical tests) by comparing traffic conditions with and without diversion strategies. The empirical findings suggest that incident diversion strategies based on predictive guidance result in travel time savings and increased travel time reliability.

    Incorporation of luminescent nanometric films in photonic crystals and devices for the development of photonic sensors2010Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Dye molecules embedded in different matrices in the form of thin films are the basis of specific materials used for laser cavities, optical filters, optical gas sensors, etc. In the present communication we discuss a new methodology based on the remote microwave plasma assisted deposition of dye containing thin films that circumvent the above mentioned problems. It permits a tailored synthesis of optically active nanometric thin films containing dye molecules which are active as fluorescence emitters (i.e., coloured and fluorescent films). The principle of this new procedure is the partial polymerization of dye molecules that are evaporated over a substrate while exposed to a remote microwave Ar plasma. As a result of this process a polymeric thin film is produced in one step where some dye molecules keep intact their optical activity (although eventually, their optical response can be slightly modified by matrix effects). This methodology has been recently used for the deposition of novel plasma nanocomposites containing non-aggregated laser dyes to maximize the fluorescent emission of the materials and for the fabrication of optical NO2 sensing nanocomposites. To illustrate the possibilities of the technique we present here results for different fluorescent dye molecules, as perylene dyes, and several xanthene and oxazine derivative cationic dyes which are typically used as gain media in tuneable laser dyes. The luminescent, optical and sensing properties of these dye containing nanocomposites will be presented. These active optical layers are being developed for the fabrication of photonic sensor devices, optical filters and photonic chips (PHODYE EU Project). This is due to the full compatibility of the synthetic methodology with the present integrated microelectronic and optoelectronic technology. The possibilities for the fabrication of photonic devices integrating these active optical layers will be demonstrated. Especial attention will be paid to recent results about the incorporation of the luminescent films in photonic crystals and about the conformal growth of luminescent planar defects within artificial opals.

    Twitter and Choreography- A Sucessful Combination?2013Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    One of the most common social media platforms of today is Twitter, an open

    community where content easily could be spread by sharing so called tweets and

    where the relationship between users is not constrained by accepting the other user.

    This report discusses the complexity in merging social media and dance by studying a

    project which used crowdsourcing through Twitter to collect choreographic ideas for

    a new ballet piece.

    In order to examine Twitter as a tool in a creative process, a questionnaire was sent to

    Twitter users and email interviews were held with those responsible for the project of

    study. The questionnaire showed that most of the Twitter users enjoyed creating and

    being part of a creative process. However, some of those with an occupation within

    the dance world voiced concerns about untrained people creating choreography.

    From the interviews it was found that a lot of thought had to be put into the structure

    of the project and that the project’s main motivator was to inspire and create with the

    help of people around the world.

    It was found in the research that Twitter is a suiting platform for a crowdsourced

    project since a large and varying group of participants is reached. Twitter allows for

    the Twitter users to participate regardless of location or occupation as well as

    bringing good publicity to the dance world.

    Tag and seek a location-based game in tainan city2014Inngår i: CHI PLAY 2014 - Proceedings of the 2014 Annual Symposium on Computer-Human Interaction in Play, Association for Computing Machinery (ACM), 2014, s. 315-318Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Tag and Seek is a location-based game which leads a traveler through Tainan City in Taiwan. The traveler's task is to find Harry's friends who are hiding at different sites in the city. Once at the site, the traveler has to scan a Near Field Communication (NFC) tag placed on a board looking like Harry's friend. When the NFC tag is scanned the lost friend is found, information about the site is presented and instructions to the next site will be available. The game lets the traveler experience culture, gain knowledge about sites in the city and meet local citizens - without the traveler having to plan the trip ahead. By implementing NFC technology as check points the interaction with the game differs from regular tourist guides and the threat of privacy which comes with location-based services is greatly lowered as the traveler is not being tracked by GPS. From our user evaluation we found that both the interface and interaction with the boards could use some improvements to increase the usability.

    Från ett fel till två rätt: en kvalitativ studie om ansatser för säkerhets- och tillsynsarbete inom svensk luftfart2017Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Luftfart har i takt med en ökad globalisering fått en naturlig roll i samhället. Samtidigt blir de teknologiska och automatiserade system som interagerar med människor och organisationer alltmer komplexa. I det fortsatta arbetet med att hålla en hög säkerhetsnivå inom civil luftfart arbetar tillsynsmyndigheter kontinuerligt med tillståndsprövning, tillsyn och analyser av luftfartens aktörer för att förhindra olyckor. För en fortsatt utveckling av säkerhetsarbetet är det av intresse att klargöra vilka säkerhetsperspektiv som i framtiden kan vara med och definiera säkerhets- och tillsynsarbetet. Teorin kring Safety-II föreslår en förändring i perspektiv på säkerhet från att så lite som möjligt skagå fel, till att fokusera på att så mycket som möjligt ska gå rätt. Safety-II definieras också som förmågan att lyckas under varierande förhållanden. Den här studiens syfte var att belysa möjligheter och utmaningar för en svensk tillsynsmyndighet att arbeta utifrån ett Safety-II-perspektiv vid tillsyn, där studien även ämnade att belysa tillämpbara beståndsdelar i Safety-II vid tillsynsarbete. För att svara på syftet genomfördes en undersökning med kvalitativ ansats genom semistrukturerade intervjuer med inspektörer vid Transportstyrelsens sjö- och luftfartsavdelning. En avgränsning mot tillsynsverksamheten drogs, där perspektiv från verksamhetsutövare uteslöts. Utmaningar som kunde identifieras med att arbeta utifrån ett Safety-II-perspektiv låg i regelverksstyrning, begreppsoklarhet och resurskrav. Även skillnader i föreskrivet och praktiserat arbete med rättvisekulturella aspekter, tvåvärdiga bedömningar och en byråkratisk tröghet kunde ses som potentiella utmaningar. Identifierbara möjligheter att arbeta utifrån Safety-II innefattade en diskret transformation av Safety-I-perspektivet, ökad dialog med verksamhetsutövare vid tillsyn samt tillgänglig kompetens internt vid myndigheten i tillägg till en positiv attityd hos inspektörer. Beståndsdelar i Safety-II tillämpbara i ett tillsynsarbete identifierades inom Transportstyrelsen i form av befintliga verktyg för fortsatt proaktivitet samt ett uppmärksammande av Resilience. En vid tillsynsmyndigheten intern människa-teknik-organisation-interaktion illustrerades även, samt en följande interaktion mellan tillsynsmyndigheten och den externa verksamhetsutövaren. Med bakgrund i studiens avgränsning, skulle en djupare insikt i problemområdet nås genom fortsatta studier som även inbegriper verksamhetsutövarens perspektiv på tillsyn och Safety-II.

    The Impact of Trade Liberalization on R&D Investments in the U.S. Manufacturing Sector2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The purpose of this paper is to contribute to the relatively small pool of literature on the relationship between import competition and research and development (R&D). Understanding the effects of increasing competition from abroad may help policymakers pursue regulatory actions to protect industries who have lost their competitiveness. At the same time, high-technological firms should me more inclined to compete with foreign competition than low-technological firms, given that the former exhibit a more elastic demand curve and absorptive capabilities. We investigate the issue by looking at nine U.S. manufacturing industries from 1991 through 2014, using publicly available R&D data from the Business R&D and Innovation Survey and tarifflevel data from World Integrated Trade Solution. We use a long, balanced panel estimated with both OLS and GMM. Results show that increased import competition forces high-tech industries to respond with increased levels of R&D. Findings also suggest a positive, but smaller, increase in R&D spending among low-tech industries as well.

    Effects of herpes simplex virus 1 (HSV-1) infection on nuclear amyloid aggregation2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Huntington’s disease (HD) and Spinocerebellar ataxia (SCA) are incurable neurodegenerative diseases that affect the central nervous system. Amyloids, highly organized protein aggregates, are a hallmark for many neurodegenerative diseases. The presence and accumulation of amyloids are toxic and constitute the major cause of neuron cell death. Both genetic and environmental factors contribute to the onset and progression of these diseases. However, despite intensive research, the underlying cause remains unclear. The role of viral infection as an environmental factor in the context of neurodegenerative diseases has not received much attention. The purpose of this study is to investigate the effects of Herpes Simplex Virus 1 (HSV-1) infection on nuclear amyloid aggregation in model cell lines of HD and SCA. The research process consists mainly of laboratory work which involved the use of several molecular techniques used in the field of biotechnology. The work comprises cultivating cells, infecting cells with HSV-1, Fluorescence microscopy, Western Blot and isolation and detection of amyloids. Western Blot is used for the analysis of specific proteins associated with protein aggregation in HD and SCA. The techniques used for detecting amyloids are Dot Blot and Antibody-staining of amyloids in cells. The results from Western Blot showed that aggregates changed in the presence of the virus. This pattern is observed for both HD and SCA1 cell lines. A big effort is done in this study to optimize Dot Blot as it is method that could be applied in every lab. Normalization of samples proved to be the most challenging part with Dot Blot. No definitive conclusions can be drawn from the Dot Blot results as reproducibility and sensitivity were lacking. This work addresses some of the difficulties encountered when working with detection of amyloids especially Dot Blot. Antibody-staining of amyloids showed that amyloids were formed in the presence of virus in comparison to non-infected. To conclude, aggregates changed, and amyloids were formed in the presence of virus. These results point to the fact that HSV-1 infection could be involved in the process of nuclear amyloid aggregation. The data presented in this thesis will need further investigation and characterization to identify the precise role of viral-induced amyloid formation in HD and SCA patient cells.

    Supporting after action review in simulator mission training: Co-creating visualization concepts for training of fast-jet fighter pilots2019Inngår i: The Journal of Defence Modeling and Simulation: Applications, Methodology, Technology, ISSN 1548-5129, E-ISSN 1557-380X, Vol. 16, nr 3, s. 219-231Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article presents the design and evaluation of visualization concepts supporting After Action Review (AAR) in simulator mission training of fast-jet fighter pilots. The visualization concepts were designed based on three key characteristics of representations: re-representation, graphical constraining, and computational offloading. The visualization concepts represent combined parameters of missile launch and threat range, the former meant to elicit discussions about the prerequisites for launching missiles, and the latter to present details of what threats a certain aircraft is facing at a specific moment. The visualization concepts were designed to: 1) perceptually and cognitively offload mental workload from participants in support of determining relevant situations to discuss; 2) re-represent parameters in a format that facilitates reading-off of crucial information; and 3) graphically constrain plausible interpretations. Through a series of workshop iterations, two visualization concepts were developed and evaluated with 11 pilots and instructors. All pilots were unanimous in their opinion that the visualization concepts should be implemented as part of the AAR. Offloading, in terms of finding interesting events in the dynamic and unique training sessions, was the most important guiding concept, while re-representation and graphical constraining enabled a more structured and grounded collaboration during the AAR.

    The Dawn of Thiol-Yne Triazine Triones Thermosets as a New Material Platform Suited for Hard Tissue Repair2018Inngår i: Advanced Materials, ISSN 0935-9648, E-ISSN 1521-4095, Vol. 30, nr 52, artikkel-id 1804966Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The identification of a unique set of advanced materials that can bear extraordinary loads for use in bone and tooth repair will inevitably unlock unlimited opportunities for clinical use. Herein, the design of high-performance thermosets is reported based on triazine-trione (TATO) monomers using light-initiated thiol-yne coupling (TYC) chemistry as a polymerization strategy. In comparison to traditional thiol-ene coupling (TEC) systems, TYC chemistry has yielded highly dense networks with unprecedented mechanical properties. The most promising system notes 4.6 GPa in flexural modulus and 160 MPa in flexural strength, an increase of 84% in modulus and 191% in strength when compared to the corresponding TATO system based on TEC chemistry. Remarkably, the mechanical properties exceed those of polylactide (PLA) and challenge poly(ether ether ketone) PEEK and today's methacrylate-based dental resin composites. All the materials display excellent biocompatibility, in vitro, and are successfully: i) molded into medical devices for fracture repair, and ii) used as bone adhesive for fracture fixation and as tooth fillers with the outstanding bond strength that outperform methacrylate systems used today in dental restoration application. Collectively, a new era of advanced TYC materials is unfolded that can fulfill the preconditions as bone fixating implants and for tooth restorations.

    Laborativt arbete inom fourieranalys och motivation till matematikinlärning: Utvärdering och vidareutveckling av en laboration inom fourieranalys och ljudbehandling vid Vetenskapens Hus2019Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Detta examensarbete undersöker om ett skolprogram på Vetenskapens Hus har förmågan att skapa en bro mellan gymnasieelevers matematikkunskap, universitetsmatematik och dess praktiska tillämpning för att därmed öka deras intresse och motivation för inlärning av matematik- och fysikämnen. Skolprogrammets tema är fourieranalys och dess tillämpning inom ljudsyntes och digital ljudbehandling (DSP). Skolprogrammet har att göra med matematik, fysik och IT, vilket gör programmet tvärvetenskapligt.

    En viktig del av detta arbete är också att vidareutveckla detta skolprogram med avseende på resultaten från denna undersökning. Resultaten är baserade på kvalitativa data från enkäter och intervjuer med eleverna som deltog i testfallen av skolprogrammet och deras lärare samt på litteraturstudier. Information samlades också in under en iterativ process av programmets vidareutveckling.

    Denna rapport inleds med motivering till genomförandet av detta arbete, studiens syfte- och målsättning samt formulering av huvudfrågeställningar. Därefter beskrivs metoder som användes för att besvara frågeställningarna. I mitten av rapporten sammanfattas litteratur och forskningsstudier inom undervisning, intresse och motivation samt sammanfattas en vetenskaplig bas för innehållet i skolprogrammet inom fourieranalys. Därefter beskrivs utvecklingsprocessen av skolprogrammet. Detta följs av en presentation av resultaten från testning av skolprogrammet med gymnasieelever med avseende på hur deras intresse och motivation påverkas av det. Rapporten avslutas med diskussion av dessa resultat och dess trovärdighet.

    Resultaten visar att den sista versionen av den laborativa aktiviteten, som vidareutvecklades inom ramen av detta arbete, väcker elevernas intresse och motivation för temat av skolprogrammet. Resultaten visar också att vissa komplexa begrepp (både nya och de som eleverna lär sig i skolan) blir klarare för eleverna efter skolprogrammet, vilket potentiellt kan leda till ökning av deras motivation till att lära sig matematik och naturvetenskap generellt. Problemet är dock att skolprogrammet testades med för få gymnasieklasser för att kunna generalisera resultatet över hela målgruppen av gymnasieelever.

    Dialogical Emergency Management and StrategicAwareness in Emergency Communication2011Inngår i: Proceedings of the 8th International ISCRAM Conference, 2011Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper introduces two concepts—dialogical emergency management and strategic awareness—as means touse and understand the content of social media for the purpose of emergency communication. Dialogicalemergency management denotes that the emergency management organizations follow what people publish invarious social media on emergencies and ongoing emergency response, and then adjust their informationstrategies in a way that matches the expectations and needs for emergency information of the public. Theconcept of strategic awareness suggests that it is essential to have an understanding of the receiver (public) ofemergency information but also to have an understanding of the receivers’ idea about the emergency andemergency response. Hence, the notion of strategic awareness incorporates structured awareness of how peopleinterpret, value, and reacts on communication based on what they think about the sender’s (emergencymanagement organization’s) actual intentions and motives.

    Thermodynamic assessment of the Fe-Te system. Part I: Experimental study2019Inngår i: Journal of Alloys and Compounds, ISSN 0925-8388, E-ISSN 1873-4669, Vol. 773, s. 314-326Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A thermodynamic description of the Fe-Te system needs to be developed in order to model internal corrosion by fission products in fuel pins of Generation IV nuclear reactors. In preparation for a thermodynamic assessment of the system, an experimental study has been performed in order to clarify some unknown or conflicting phase diagram data. New phase diagram data have been obtained using Differential Thermal Analysis and isothermal heat treatments followed by electron microscopy with EDS and WDS analysis. The DTA analysis revealed new phase boundary data, and confirmed a very steep Fe-rich liquidus, supporting the possibility of a liquid miscibility gap in the Fe-FeTe region. The analyses also confirmed the probable eutectoid reaction δ→β+δ’ at 523 °C. The invariant arrests of the unknown γ phase were consistent with information available in literature, but the phase was not identified via XRD of samples at its postulated composition. However, metallography of the samples revealed an unexpected microstructure pertaining to the δ phase, which might be the γ phase, and is discussed in this paper. The monoclinic space group C2/m is proposed for the δ phase based on XRD. The collected data will be used together with that available in literature to perform a thermodynamic Calphad assessment in a subsequent paper Part II: Thermodynamic modeling.

    Mining Frequent Patterns in Evolving GraphsManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Given a labeled graph, the frequent-subgraph mining (FSM) problem asks to find all the k-vertex subgraphs that appear with frequency greater than a given threshold. FSM has numerous appli- cations ranging from biology to network science, as it provides a compact summary of the characteristics of the graph. However, the task is challenging, even more so for evolving graphs due to the streaming nature of the input and the exponential time complexity of the problem. In this paper, we initiate the study of approximate FSM problem in both incremental and fully-dynamic streaming settings, where arbitrary edges can be added or removed from the graph. For each streaming setting, we propose algorithms that can extract a high-quality approximation of the frequent k-vertex subgraphs for a given threshold, at any given time instance, with high probability. In contrast to the existing state-of-the-art solutions that require iterating over the entire set of subgraphs for any update, our algorithms operate by maintaining a uniform sample of k-vertex subgraphs with optimized neighborhood-exploration procedures local to the updates. We provide theoretical analysis of the proposed algorithms and emprically demonstrate that the proposed algorithms generate high-quality results compared to baselines.

    Wire electronics and woven logic, as a potential technology for neuroelectronic implantsManuskript (Annet (populærvitenskap, debatt, mm))
    Abstract [en]

    New strategies to improve neuron coupling to neuroelectronic implants are needed. In particular, to maintain functional coupling between implant and neurons, foreign body response like encapsulation must me minimized. Apart from modifying materials to mitigate encapsulation it has been shown that with extremely thin structures, encapsulation will be less pronounced. We here utilize wire electrochemical transistors (WECTs) using conducting polymer coated fibers. Monofilaments down to 10 μm can be successfully coated and weaved into complex networks with built in logic functions, so called textile logic. Such systems can control signal patterns at a large number of electrode terminals from a few addressing fibres. Not only is fibre size in the range where less encapsulation is expected but textiles are known to make successful implants because of their soft and flexible mechanical properties. Further, textile fabrication provides versatility and even three dimensional networks are possible. Three possible architectures for neuroelectronic systems are discussed. WECTs are sensitive to dehydration and materials for better durability or improved encapsulation is needed for stable performance in biological environments.

    Biocompatibility of PEDOT/biomolecular composites intended for neural communication electrodesManuskript (Annet (populærvitenskap, debatt, mm))
    Abstract [en]

    Electrodes of the conjugated polymer poly(3,4-ethylene dioxythiophene) (PEDOT) have been shown to possess very attractive electrochemical properties for functional electrical stimulation (FES) or recording in the nervous system. Biomolecules already present in nervous tissue, added as counter ions in PEDOT electropolymerisation, could be a route to further improve the biomaterial properties of PEDOT, eliminating the need of surfactant counter ions like docedyl benzene sulphonate (DBS) or polystyrene sulphonate (PSS) in the polymerisation process. Such PEDOT/biomolecular composites using heparin, or hyaluronic acid, have been electrochemically investigated in a previous study and have been shown to retain the attractive electrochemical properties already proven for PEDOT:PSS.

     

    The aim of the present study is to evaluate biocompatibility of these PEDOT/biomolecular composites in vitro and also evaluate PEDOT:heparin biocompatibility in cortical tissue in vivo. Hereby, we also aim to identify a suitable test protocol, that can be used in future evaluations when further material developments are made.

     

    Material toxicity was first tested on cell lines, both through a standardised agarose overlay assay on L929 fibroblasts, and through elution tests on human neuroblastoma SH-SY5Y cells. Subsequently, a biocompatibility in vivo test was performed using PEDOT:heparin coated platinum probes implanted in the cerebral cortex of Sprague-Dawley rats. Tissue was collected at three weeks and six weeks of implantation and evaluated by immunohistochemistry.

     

    No cytotoxic response was seen to any of the PEDOT:biomolecular composites tested here. Furthermore, elution tests were found to be a practical and effective way of screening materials for toxicity and had a clear advantage over the agarose overlay assay, which was difficult to apply on other cell types than fibroblasts. Elution tests would therefore be recommendable as a screening method, at all stages of material development. In the in vivo tests, the stiffness of the platinum substrate was a significant problem, and extensive glial scarring was seen in most cases irrespective of implant material. However, quantification of immunological response through distance measurements from implant site to closest neuron, and counting of macrophage densities in proximity to polymer surface, was comparable to those of platinum controls. These results indicate that PEDOT:heparin surfaces were as compatible with cortical tissue as pure platinum controls.

    This paper presents the SWAY prototype that encourages people to explore aspects around balance and posture in a playful way. The prototype senses small movements and shifts in posture using a Kinect sensor, and translates these movements to the tilting of a platform holding a set of marbles, and to haptic feedback in the form of vibrations. The prototype provides an interactive experience focusing on building body awareness with a particular focus on balance and posture. The design inquiry provided new insights with respect to reinforcement of bodily experiences and how different modalities affect the guiding of attention.

    Automatic construction of models for analytic system-level design space exploration problems2017Inngår i: Proceedings of the 2017 Design, Automation and Test in Europe, DATE 2017, Institute of Electrical and Electronics Engineers (IEEE), 2017, s. 670-673, artikkel-id 7927074Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Due to the variety of application models and also the target platforms used in embedded electronic system design, it is challenging to formulate a generic and extensible analytic design-space exploration (DSE) framework. Current approaches support a restricted class of application and platform models and are difficult to extend. This paper proposes a framework for automatic construction of system-level DSE problem models based on a coherent, constraint-based representation of system functionality, flexible target platforms, and binding policies. Heterogeneous semantics is captured using constraints on logical clocks. The applicability of this method is demonstrated by constructing DSE problem models from different combinations of application and platforms models. Time-triggered and untimed models of the system functionality and heterogeneous target platforms are used for this purpose. Another potential advantage of this approach is that constructed models can be solved using a variety of standard and ad-hoc solvers and search heuristics.

    Placeringen av grafiska komponenter och dess påverkan på upplevt förtroende2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    I takt med att e-handeln ökar så påverkas kundernas köpvanor. Detta har i sin tur lett till att företagens säljbeteende har förändrats. Att bygga upp förtroende gentemot kunder är grundläggande eftersom en ökad trovärdighet inte bara eliminerar känslan av osäkerhet utan även bidrar till en ökad köpintention. För att kunna bygga upp förtroende så gäller det att förstå vikten av webbplatsens kvalitet och utformning. I denna uppsats tittar vi närmare på produktsidan, då vi anser att det är en av de viktigaste sidorna på en webbutik. Syftet med denna uppsats är att bidra med ökad kunskap om hur layout och formgivning av innehåll ökar eller minskar kundens förtroende till en webbutik. För att kunna identifiera huruvida placeringen av grafiska komponenter såsom produkttitel, produktpris, köpknapp och navigationsmeny har någon betydelse ställer vi frågan: Påverkar placeringen av grafiska komponenter på en e-handelsplattform kunders förtroende? Begreppet förtroende definieras utifrån det initiala förtroendet, där en potentiell kund bedömer trovärdigheten baserat på ytliga faktorer. Då kunden är villig att lita på och genomföra ett köp på en webbplats och därmed villig att ta risker. För att kunna besvara detta genomfördes en enkätstudie med 27 deltagare. I enkäten fick testdeltagarna sedan rangordna prototyper där placeringen av de grafiska komponenterna varierats. Deltagarna fick rangordna prototyperna efter både förtroende och tillit på grund av risken med tolkningsskillnader av begreppet förtroende. Resultatet visade, trots det låga antalet deltagare, att förflyttningen av komponenterna troligtvis har en påverkan på upplevt förtroende.

    System for Automated Assistance in Correction of Programming Exercises (SAC)2008Inngår i: Proceedings of CIDUI 2008, Lleida (Spain), 2008, s. 104-113Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    In university programming classes often hundreds of students participate having to solveeach hundreds of programming assignments a situation which puts instructors to the difficult task of validating hundreds of programming assignments. We present a framework thatcan help instructors and students in organization and validation of program code. Our “System for Automated Assistance in Correction of Programming Exercises“ (short: SAC) is aweb-platform for test-driven development and automated validation. The web-platform isbased on Java Server Pages technology with tomcat as servlet container, and allows teachersto specify and define program exercises and students to upload their solutions. Students can get immediate feedback on the validity of their code and both instructors and students cansee statistics about each programming assignment. We explain our platform and proposehow the automatic validation can be extended.

    A virtual poster presenter using mixed reality2017Inngår i: 17th International Conference on Intelligent Virtual Agents, IVA 2017, Springer, 2017, Vol. 10498, s. 25-28Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this demo, we will showcase a platform we are currently developing for experimenting with situated interaction using mixed reality. The user will wear a Microsoft HoloLens and be able to interact with a virtual character presenting a poster. We argue that a poster presentation scenario is a good test bed for studying phenomena such as multi-party interaction, speaker role, engagement and disengagement, information delivery, and user attention monitoring.

    Potential Utilization of Municipal Organic Solid Waste: Case Study: Dhaka City Corporation Area, Bangladesh2014Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Municipal solid waste management is a concern of high priority for any city authority. Without proper management of this waste great problems may occur for society. Dhaka, the capital of Bangladesh, is a developing city. The population load and energy demand is increasing day by day. The city authority, Dhaka City Corporation (DCC), is responsible for managing the city’s solid waste.

    In Dhaka city waste is collected from door to door then put into dustbins and finally transported and dumped in the landfill sites. This unplanned waste management system creates environmental problems, such as water pollution and metal contamination, as well as social and health problems, for example skin diseases, headache, vomiting, and increases in mosquitoes, flies, and bad odour. Since the generated waste has more than 50% organic content, it can be a good source for energy generation.

    New technological solutions and a systematic approach can be a great option for management of waste. In Dhaka City Corporation Area this study addresses anaerobic digestion as a new option for energy generation. Among various types of existing technologies based on the climatic factor, waste stream, social and cultural factors, and environmental factors, the anaerobic treatment method is considered the best possible alternative method. The environmental system analysis tool, cost benefit analysis, is used in combination with the technology for determining the suitability of the system.

    By analysing technological treatment methods and environmental system analysis tools, comparisons are conducted between the present situation and a proposed scenario. The comparisons were conducted based on various considerations, such as net present benefit of total life time, net present benefit considering only economic value, net present benefit considering economic value including environmental and social value, and so on. In all cases, values for the proposed project show positive outcomes and for the present scenario they show negative ones. By analysing an environmental system analysis approach of anaerobic digestion of proposed project, it can be considered as a beneficial project for the DCC authority from environmental, social, and economic points of view.

    Bridging educational and working environments through pervasive approaches2017Inngår i: 3rd International Joint Conference on Serious Games, JCSG 2017, Springer Verlag , 2017, s. 296-307Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In the education of mechanical engineers alternative learning methods like serious games, simulations etc. have been used in past decades to better the learning outcomes. However, a main concern is still the amount of resources used on adapting and modding games as well as the challenges related to the implementation in the class room setting. Typically a positive learning experience does not only rely on the game as such, but how good the facilitator or teacher is to change game mechanics and the narratives so that players with different learning curves, past experience and cognitive abilities all stay in flow and feel immersed. Physical simulation games played in a workshop setting often have this ability, whereas this still seems to be a challenge in digitalized games. The main purpose of this article is to identify mechanics that need to be adapted differently for different user groups in order to keep them in flow, motivated and engaged in order to have a high learning experience and how we can take advantage of technologies like VR to reduce the costs and the resources.

    Playing close to home: Interaction and emerging play in outdoor play installations2018Inngår i: CHI '18 Proceedings of the 2018 CHI Conference on Human Factors in Computing Systems, Association for Computing Machinery (ACM), 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Outdoor play is becoming an increasingly marginalised activity in the urban landscape. Even in HCI, research on interactive solutions for outdoor play has largely been limited to special areas and in particular playgrounds. But children play everywhere, and especially play close to home is central in children's play activities. In this article we draw upon knowledge about designing for children's play in interaction design as well as in landscape architecture, to study how interactive play installations can be integrated in outdoor environments of a residential area. We present a field study in which digitally enhanced play installations were installed, in dialogue with the landscape, in between the buildings of a residential area. We focus on how emerging play activities made use of the installations as well as of the surrounding landscape in expected as well as unexpected ways. Based on the observations, we discuss how residential play is special, and how this affects how to design for it.

    Agile Project Portfolio Management Challenges2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Globalization allows companies to reach a larger customer base and to focus on niche markets, driving specialization. Conversely, it also lets customers choose from a wider array of options on any given market, which all together leads to increased competition. Such global scale competition is straining profitability and urges companies to innovate both strategy and operations in search of competitive advantages. The ensuing increased rate of change has placed an emphasis on achieving flexibility to ensure alignment with market needs, with companies successful in quick modifications flourishing even in face of unpredictable and unceasing turbulence. The trend toward increasing turbulence is acutely experienced by the automotive industry. Due to the commoditization of hardware in light of digitalization, the automotive industry is undergoing a shift in profitability toward software. The adaptation of strategy to the market is vital to survival, which in turn means that the operationalization of the strategy is crucial. One way to actualize the strategy is through project portfolio management (PPM). As corporate strategy and project portfolios are tightly connected, PPM is essential to implementing the strategy. It is of interest to study the flexible qualities of PPM in an individual industry moving from stable to turbulent, in order to gain insight into the challenges of that industry. The flexible properties of PPM in the automotive industry is thus of utmost importance to the survival of companies. The built-in flexibility of PPM is however not always enough and there is an increasing interest in agile PPM (APPM). So far, there is little advancement on the topic of APPM, and the need for further understanding is obvious with consideration to recent market developments, especially in the automotive industry. This thesis has employed a single case study to understand what challenges traditional companies in the automotive industry face when trying to become more agile in their project portfolio management in order to align their organization around agile practices on the team level and increase responsiveness to external changes. Adopting an abductive approach, empirical data was collected using interviews, observations, documents as well as a survey. The results of this study are twofold. Firstly, an exhaustive mapping of a major automotive company’s PPM process is presented. Secondly, this mapping is utilized to establish what PPM processes could be made more agile and what the main challenges are.

    A new Fennoscandian crustal thickness model based on CRUST1. 0 and a gravimetric–isostatic approach2015Inngår i: Earth-Science Reviews, ISSN 0012-8252, E-ISSN 1872-6828, Vol. 145, s. 132-145Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    In this paper a new gravimetric–isostatic crustal thickness model (VMM14_FEN) is estimated for Fennoscandia. The main motivation is to investigate the relations between geological and geophysical properties, the Moho depth and crust–mantle density contrast at the crust–mantle discontinuity. For this purpose the Bouguer gravity disturbance data is corrected in two main ways namely for the gravitational contributions of mass density variation due to the different layers of the Earth's crust such as ice and sediments, as well as for the gravitational contribution from deeper masses below the crust. This second correction (for non-isostatic effects) is necessary because in general the crust is not in complete isostatic equilibrium and the observed gravity data are not only generated by the topographic/isostatic masses but also from those in the deep Earth interior. The correction for non-isostatic effects is mainly attributed to unmodeled mantle and core boundary density heterogeneities. These corrections are determined using the recent seismic crustal thickness model CRUST1.0. We compare our modeling results with previous studies in the area and test the fitness. The comparison with the external Moho model EuCRUST-07 shows a 3.3 km RMS agreement for the Moho depth in Fennoscandia. We also illustrate how the above corrections improve the Moho depth estimation. Finally, the signatures of geological structures and isostatic equilibrium are studied using VMM14_FEN, showing how main geological unit structures attribute in isostatic balance by affecting the Moho geometry. The main geological features are also discussed in the context of the complete and incomplete isostatic equilibrium.

    Research on the interaction between streamwise streaks and Tollmien-Schlichting waves at KTH2007Inngår i: ERCOFTAC Bulletin, ISSN 2518-0991, Vol. 74, s. 37-43Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper summarises the experimental and numericalinvestigations on how two different types of disturbancesmay, in a positive way, interact in a flat plateboundary-layer flow. The project, which mainly hasbeen centered at KTH1, has been performed in collaborationwith colleagues from University of Bologna2and LadHyX CNRS Ecole Polytechnique3, duringthe last years. The main phenomena — the stabilisingeffect of streamwise boundary-layer streakson Tollmien-Schlichting waves (and other exponentialdisturbances) — have been captured both in experiments[1, 2] and with different numerical approachessuch as direct numerical simulations [3], parabolicstability equation calculations [5] and large-eddy simulations[6]. We will here briefly review the methodsand the main results of these studies, and discuss howthey correlate with each other.

    The role of earthquake warning systems2018Inngår i: ISRM International Symposium 2000, IS 2000, International Society for Rock Mechanics , 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The fact that each year thousands of people in seismically active parts of the world are killed or injured due to major earthquakes urges for continuous efforts in order to lessen the size of the catastrophe. Technical achievements made in recent years have made it possible to install an Earthquake Warning System (EWS) that can issue alarm a few seconds before the damaging waves reach the area. The main idea behind such systems is to make use of the difference between the propagation velocity of S-waves, and radio waves to issue earthquake alarm before arrival of the destructive part of the seismic waves. As the efficiency of an EWS depends on many factors, each area must particularly be studied in order to determine if such a system would be appropriate or not. In this paper EWS has been studied as a complementary measure against earthquake in Iran a country with more than 100,000 casualties due to earthquakes in recent decades. A simplified method has also been suggested for comparing the costs of the project with the economical advantages of it. Using the suggested method it has been shown that an EWS would be both economical and efficient in some parts of the country.

    Riskanalys av elsystem med funktions-FMEA2014Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Riskanalysverktyget failure mode and effects analysis (FMEA) som analyserar kompo-nenter och signaler är beroende av att designen av fordonets elsystem finns tillgängligt och utförs därför sent i utvecklingsprocessen av elsystem. Detta medför att vissa fel inte analyseras i tid och kanske måste designas bort i efterhand vilket kan leda till ökad sy-stemkomplexitet samt längre och dyrare utvecklingsprocesser.Målet med examensarbetet är att genom en litteraturstudie ta reda på om det finns me-toder eller arbetssätt som gör att Scania tidigt i utvecklingsprocessen av elsystem kan genomföra funktionsanalyser i sitt riskanalysarbete med FMEA samt analysera dessa.Resultatet av detta examensarbete visar att det är möjligt att påbörja FMEA-arbetet tidigt i utvecklingsprocessen av elsystem om ingenjörerna utgår från ett funktionsperspektiv i riskanalysarbetet där de listar och rangordnar de funktioner som tillsammans realiserar en eller flera funktionaliteter samt deras felmoder, feleffekter, feldetektering, allvarlighet, sannolikhet och frekvens. Med hjälp av en FFMEA kan ingenjörerna tidigt i utveck-lingsprocessen av elsystem snabbt och effektivt hantera de identifierade säkerhetskritiska funktionerna.En befintlig funktionalitet på Scania har brutits ned i funktioner och en FFMEA har genomförts på dessa som en demonstration på hur en FFMEA kan genomföras och se ut.
