    Building Networks for Delivering Integrated Product-Service Offerings (IPSOs)2010Ingår i: Industrial product-service systems -IPS²: proceedings of the 2nd CIRP IPS² Conference [2010, Linköping, 14-15 April], Linköping, 2010Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper describes the effect of forming business networks and collaborations for the purpose of developing an Integrated Product-Service Offering (IPSO) using the Product/Service Systems (PSS). The research method is an in-depth case study of a joint venture formed by four companies developing a new technology for chemical extraction from water sludge waste within the pulp and paper industry.Combining literature from PSS, network theories and collaborative product development, this paper puts forward the benefits for SMEs to collaborate in business networks and produce IPSOs when introducing a new technology in an emerging market. The case study shows that working towards the new market would not have been possible if each party acted individually or maintained their traditional buyer-supplieroperator roles, and that IPSOs can reduce the business risk.

    A design solution for prevention of pressure ulcers: A sensor driven bedding for hospital beds that detect pressure2021Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Denna rapport handlar om prevention av trycksår (liggsår). Examensarbetet av en student vidLuleå Tekniska Universitet inom Teknisk design under våren 2021. Trycksår är ett besvärligtoch jobbigt problem som finns överallt inom sjukvården. De uppstår på människor som liggereller sitter i samma position en längre tid, där kroppens tyngd skapar ett tryck mot underlaget.Det bidrar till att blodgenomflödet i hud och underhudsvävnader minskar eller upphör vilketleder till trycksår.

    Intresset för arbetet kom till efter att ha fått kontakt med Per Söderberg, där han berättadeom uppdraget han arbetat med och inte kunnat släppa, efter att ha gått i pension. Uppdragethandlade om att läka och förebygga trycksår genom en sängvagga CUNIDORM som Perskapat. Per fastnade med sin idé på grund av dålig design och sökte sig vidare efter någon somkunde se uppdraget från ett nytt perspektiv. Syftet med projektet blev att hitta en lösning somförebygger trycksår från att uppstå.

    För att lösa problemet användes en iterativ designprocess PCDIO (Planning, Conceive,Design, Implement & Operate) som utfördes med HCD (Human-Centered design) somtankesätt eftersom lösningen är avsedd för människan. I början av processen genomfördeskontextfasen. Där bestämdes behoven genom intervjuer och forskning på nuläget. Störstabehoven som identifierades var behovet av att minska vändningar och granskningar avpatienterna. Granskning är den främsta metoden för att förebygga trycksår. Behovet av bramaterial identifierades då en orsak till trycksår var fukt och värme. Efter att användarbehovenupptäckts användes olika metoder inom ramarna av programmet Teknisk Designs för attskapa idéer och koncept.

    Det resulterade i tre koncept, luftmadrassen, skummadrassen med mekaniska armar ochmadrassen med sensorer. Koncepten utvärderades utifrån en designspecifikation där depoängsattes. Det koncept som uppfyllde kriterierna bäst med högst poäng blev det vinnandekonceptet.

    Resultatet blev SENSAI, madrassen som känner av patientens tyngd under en tidsperiod medhjälp av sensorer. Den detekterar vart trycket är som mest och hur skadligt det är. Genom attdetektera tryck och belastning kan potentiella trycksår upptäckas tidigare. Produkten har intetestats med hjälp av prototyper eller liknande på grund av pandemin och bristande tillgångtill material. Slutsatsen för detta projekt är att utföra fler tester och undersökningar.Förhoppningsvis kommer detta att ske som fortsatt arbete efter examensarbetets slut.

    User Interface Design for Quality Control: Development of a user interface for quality control of industrial manufactured parts2020Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Den förväntade kvalitén på tillverkade delar inom bilindustrin är väldigt hög, med toleranser på så lite som tiondels millimeter många gånger. De konventionella metoderna som används för att kontrollmäta de tillverkade delarna idag är mycket noggranna, men de är både tidskrävande och otillräckliga och endast en väldigt liten del av en producerad serie blir kontrollmätt idag. Mätningen utförs manuellt i så kallade mätfixturer. Där varje komponent fixeras och förutbestämda undersökningspunkter kontrolleras med en så kallad mätklocka. Dessa fixturer är även väldigt dyra att tillverka och de är bara kompatibla med en specifik komponent. I dagens läge så kasseras otroligt stora mängder material från dessa komponenter inom bilindustrin. Här finns det alltså ett stort behov för att öka mängden komponenter som kontrolleras utan att påverka tillverkningstakten. Det här projektet utfördes åt det relativt nystartade företaget Viospatia, vilket är ett spin-off företag från forskning utförd vid Luleå tekniska universitet. De har utvecklat ett system som med hjälp av fotogrammetri automatiskt mäter av varje komponent direkt i produktionslinan. Detta gör att eventuella fel upptäcks nästan omedelbart samtidigt som tillverkaren får en tydligare bild av sin produktion och dess kapacitet. Syftet med denna masteruppsats har varit att undersöka hur ett gränssnitt bör utvecklas för att det ska bli så användarvänligt som möjligt utan att begränsa systemets viktiga funktioner. Målet har varit att ta fram ett förslag på ett gränssnitt som är anpassat för den tänkta användaren, som skapar ett mervärde och är enkelt att använda. Processen har följt en användarcentrerad struktur fördelaktig för interaktionsdesign, där utvecklingsfasen bestående av analys, design och validering sker i flera iterationer med kontinuerlig återkoppling med användare och uppdragsgivare. Kontexten, där den tänkta lösningen ska användas, undersöktes initialt hos de involverade företagen. I projektet var tre fabriker involverade, Gestamp Hardtech och Scania Ferruform i Luleå och Volvo Cars i Olofström. Dessa fabriker använder mestadels liknande tillverkningsmetoder, metallpressning, vilket gör att de rimligtvis har en del gemensamma förutsättningar och behov. Under arbetets gång har diverse kreativa metoder använts för att generera så mycket idéer som möjligt utan att förbise viktiga aspekter. Till en början utvecklades prototyper analogt för att sedan utvecklas till digitala interaktiva prototyper. Ett större användbarhetstest genomfördes på distans med sju testpersoner via en länk till den digitala prototypen. Med hjälp av responsen från dessa tester gjordes en del ändringar och den slutliga designen på gränssnittet blev uppdelat i två nivåer, Supervisor och Operator. Genom teoristudie och användartester framgick det att operatören behöver få en omisskännlig uppmaning från gränssnittet. Det bör inte uppstå några som helst tveksamheter och operatören skall kunna agera direkt. Denna uppmaning sker genom en tydlig färgkodning som utnyttjar vedertagna uppfattningar om färgers innebörd. Genom att identifiera vilka behov de olika aktörerna har kan man på så sätt också hålla isär de olika funktionerna och göra de tillgängliga endast för den typen av aktör som behöver de. De kan på så sätt också utvecklas mer specifikt för den tänkta aktören istället för att modifieras för att passa alla. Denna separering av funktioner är inget som användaren behöver ställa in själv utan görs automatiskt då den loggar in med sitt användarkonto.

    Nanosatellite Telemetry Processing2023Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Nowadays, new economic models advocating agility and innovation are emerging in the space sector, this is the “New Space”. New nanosatellites, micro-launchers and other new technologies make it easier to access and use space. For this reason, in December 2019, HEMERIA launched in partnership with CNES its first nanosatellite named Argos Neo on a Generic Economical and Light Satellite (ANGELS), currently in orbit and operational. ANGELS aims to validate the concept of a nanosatellite demonstrator of the platform's equipment and to validate the payload allowing satellite coverage for Argos beacons. Retrieving and analysing satellite telemetry is therefore essential. After studying ANGELS architecture, I developed new and more accurate Python scripts to analyse telemetry (including daily averages instead of monthly averages). Then, I validated and verified Python scripts results thanks to a comparison with current ANGELS activities reports. Finally, I compared Telemetry with the results of electrical and thermal prelaunch analyses (PDR and CDR reviews). Thus, the analysis between the pre-launch studies and Telemetry allowed to identify areas of improvements providing useful feedback for the new KINEIS constellation development.

    The Production Mirror: How an interactive interface can boost motivation for industrial workers2019Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Detta examensarbete handlar om industriarbetaresmotivation kan påverkas av informationsspridning genomett interaktivt gränssnitt. Fokus i detta arbete har legat påatt undersöka mänskliga motivatorer i teorin för att sehur dessa kan appliceras i en industriell miljö medförhoppning om att ge arbetaren en djupare kunskap omföretagets produkt och/eller process och således ökadennes förståelse för det dagliga arbetet som bedrivs inomföretaget. Projektet bygger på ett antagande om att enökad insikt och insyn i mer än vad som begränsas avarbetarens arbetsuppgifter kan ha en positiv effekt ochförstärka dennes känsla för sin roll i ett störresammanhang och även ge en ökad motivation.Arbetet redovisar också hur en designprocess kanappliceras på ett organisatoriskt problem inom industrier,där de olika faserna i processen inkluderar berördamänniskor repetitivt för att söka kunskap, idéer ochlösningar tillsammans med dem som kan tänkas bliberörda av arbetets resultat.På industrier idag är det vanligt att arbetet är fördelat överavdelningar där personalen är indelad i olika team där detförekommer viss arbetscirkulation inom avdelning menmindre vanligt över avdelningsgränser. Detta kan limiteraarbetarens uppfattning för hela processen och resultera i endetaljerad förståelse endast för en begränsad del avprocessen.Industri 4.0 förväntas vara lösningen på att hämta hem ochbehålla företag i Europa genom att bygga smarta fabrikermed teknik som tillåter maskinerna att kommunicera.Industri 4.0 förväntas även att minska antalet som jobbatinom industrier, mänskliga interaktioner och ansvar. Vilketkan ha den negativa effekten att förstärka en av dagensproblem ytterligare, arbetaren blir ytterligare isolerad ifrånprocessen. Vilket är faktorer som enligt teorin bidrar till enminskad motivationsnivå och kommer därför ha en negativpåverkan på deras arbetsambitioner.Arbetet har genomförts med RISE Interactive i Piteå somuppdragsgivare. RISE är en del av vårt svenskaforskningsinstitut och jobbar med användarcentreradteknisk utveckling inom många olika branscher.Examensarbetet resulterade i en stor idémängd för hurarbetet inom industrier skulle kunna dra nytta av ettinteraktivt gränssnitt för att sprida information ochkunskap. Den slutliga lösningen är presenterad i enstopmotion film som visar den lösningen som blev framröstad av industriarbetare. Lösningen visar hur färgadelampor kan användas för att synliggöra progressrelateradinformation under arbetets gång samtligt som det möjliggörenkel kommunikation mellan medarbetarna.

    Evaluation of Car Engine Sound Design Methods in Video Games2021Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Realistic interactions with sound objects in video games are a contributing factor to the overall immersion. Car engine sound design is an area where the auditory feedback from driving would have an impact on that immersion. For this study, three methods for designing car engine sounds are evaluated. A traditional method in the game sound industry is to use several sampled audio recordings for the reproduction of engine sounds, which is in this study represented as a sample-based model. The sample-based model is evaluated together with a model using granular synthesis in an in-game scenario. A less common method is to use physical modeling, which is in this study evaluated together with the other two models in a listening test. Results show the granular synthesis model to be the most realistic, and the physical model to be the least preferred.

    Perceived audio quality of compressed audio in game dialogue2016Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    A game could have thousands of sound assets, to fit all of those files to a manageable storage space it is often necessary to reduce the size of the files to a more manageable size so they have to be compressed. One type of sound that often takes up a lot of disc space (because there is so much of it) is dialogue. In the popular game engine Unreal Engine 4 (UE4) the the audio is compressed to Ogg Vorbis and has as default the bit rate is set to 104 kbit/s. The goal of this paper is to see if untrained listeners find dialogue compressed in Ogg Vorbis 104 kbit/s good enough for dialogue or if they prefer higher bit rates. A game was made in UE4 that would act as a listening test. Dialogue audio was recorded with a male and a female voice-actor and was compressed in UE4 in six different bit rates. 24 untrained subjects was asked to play the game and identify the two out of six robots with the dialogue audio they thought sound the best. The results show that the subjects prefer the higher bit rates that was tested. The results was analyzed with a chi-squared test which showed that the null-hypothesis can be rejected. Only 21% of the answers were towards UE4s default bit rate of 104 kbit/s or lower. The result suggest that the subjects prefer dialogue in higher bit rates and UE4 should raise the default bit rate.

    Attenuation AND awareness?: Designing a method for measuring accuracy and certainty of sound identification when wearing a HPD2020Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Bullerföroreningar är ett utbrett problem i dagens samhälle, från trafik till industriella källor, och många människor är låsta till en ohälsosam akustisk miljö via sin anställning. När buller inte kan elimineras vid ljudkällan är skyddsåtgärden vanligtvis att förse arbetstagaren med hörselskydd, exempelvis hörselkåpor, som dämpar bullret. Att använda en överdriven dämpning kan dock göra att användaren avskiljs helt från sin akustiska miljö och innebära risker samt social isolering. Hörselskydd utrustade med nivåberoende funktion (LDF) använder mikrofoner tillsammans med en signalbehandlingsenhet och interna högtalare för att uppnå flexibilitet i dämpningen – om omgivande buller är lågt kan högtalarna förstärka ljudet för att motverka en överdriven passiv dämpning erbjuden av hörselskyddet, om omgivande buller däremot är högt kan denna förstärkning minskas för att vidhålla sunda ljudnivåer.

    Lämpliga dämpningsnivåer gör att användaren kan upptäcka omgivande ljud som bidrar till deras situationsmedvetenhet. Förutom att dämpa ljuden så ändrar dock hörselskydd också det spektrala innehållet i ljudet vilket kan komplicera förmågan att identifiera ljuden. Denna masteruppsats har fokuserat på att utforska människans förmåga att identifiera ljud, utforma en metod för att mäta denna förmåga, implementera metoden och utvärdera dess resultat samt metoden i sig. Uppsatsen har genomförts i samarbete med 3MTM PeltorTM och var avsedd att utvärdera effekten av hörselkåpor, utrustade med LDF, på förmågan att identifiera ljud i ett ljudlandskap likt det i en processindustri.

    Projektet var strukturerad enligt Double Diamondprocessen, där litteraturstudier, benchmarking och workshops har informerat och väglett arbetet och resulterat i en metod som analyserats med hjälp av variansanalys baserat på empiriska data från 16 deltagare. Överraskande nog så visade resultaten ingen statistiskt signifikant fördel med att bära ett hörselskydd som är utrustat med LDF till skillnad från ett hörselskydd som saknar denna funktion, vad gäller användarens förmåga att korrekt identifiera ljud samt rapporterad säkerhet i svaren. Orsaker till detta diskuteras med fokus på att utvärdera användbarheten av den utformade metoden i framtida ansträngningar för att utveckla hörselskydd som erbjuder tillförlitlig ljudidentifiering.

    Reliability Centered Maintenance: Different Implementation Approaches2016Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Mining equipment are becoming very sophisticated and complex. At the same time, mining companies modernise its operation by increased mechanisation and automation (Dhillon, 2008). That requires well-developed and planned maintenance strategy. A proper maintenance strategy and appropriate maintenance actions, are essential to keep equipment safe & reliable, decrease the overall costs, and it helps to eliminate workplace hazards. Maintenance strategies and maintenance actions, in turn, are changed and developed more than any technology (Moubray, 1997). Changing and developing of the maintenance can be due to many factors, perhaps due to the complexity of the systems or due to the development of the technology. One of the best research (developed technology) that has been done in this area is the research by Nowlan and Heap about Reliability Centered Maintenance (RCM) in 1978. RCM is defined as, “a zero-based, structured process used to identify the failure management strategies required to ensure an asset meets its mission requirements in its operational environment in the safest and cost – effective manner” (Regan, 2012). The RCM is one of the best powerful asset management strategies. RCM can be applied to any asset, nuclear power plant, aeroplane, or truck ship. According to (Nowlan & Heap, 1978), the main goal of implementation an RCM process is to provide the stated function of the facility with required reliability and availability at the lowest cost. In this master thesis, an RCM analysis process has been described in details. Moreover, two types of implementation approaches of an RCM analysis process have also been described. The intention of describing these two approaches is to see what the differences between them are and which one can be recommended for using in mining. The first approach is according to (Hinchcliffe & Smith, 2004) and the second approach is according to (Regan, 2012). Moreover, in this master thesis, there are also two case studies that have been analysed. The intention of analysing these two case-studies is to see how the RCM has been implemented. As a result of the research carried out in this master thesis, some basic streamline RCM analysis process has been recommended for using in mining. This recommended RCM analysis process could be applicable to be used in every industry section. The result of this work can be summarised that RCM is an applicable tool which can be used in mining for selecting the right maintenance approach for different equipment, systems or subsystem. RCM analysis process is discussed from different perspective. In the discussion, the misconceptions about the implementation of an RCM analysis process have been discussed. Altogether, Reliability Centered Maintenance is one of the most powerful asset management strategies that can be used in every industry section. If the RCM is applied by right people and by the right way, the result can be profitable for the mining companies.

    Public procurement of railway infrastructuremaintenance: a literature review2017Konferensbidrag (Refereegranskat)
    Abstract [en]

    The maintenance of railway infrastructure has in several instances been changed from government-based to being based on public procurement, with varying degrees of flexibility for the contractor to design their maintenance work. The purpose of-giving contractors a larger freedom of choice of how to perform maintenance is to stimulate them to innovate and develop their maintenance processes. Since the contracts differ in between and there are changes in government policies over time that affects both existing and new contracts, a comparison between different contracts becomes challenging. A literature review has been conducted to understand the change in procurement strategy and how to encourage contractors to innovate. The research questions include: What procurement strategies are there? How is maintenance evaluated? How does procurement affect the innovation opportunities for entrepreneurs?

    The literature review focuses on railway maintenance and contract design between client and contractor. In total, 17 articles matched the search criteria and were selected for the review. To have successful maintenance service, five articles suggested partnering as a strategy with common goals in combination with good communication during the entirety of the contract. When selecting incentive plan, four articles mentions that a focus on performance-based incentives in combination with riskmanagement is better rather than actual payment schemes. The reason being that payment is often themain cause of conflicts between client and contractor. The scientific literature suggests that improvement in incentives improves quality of maintenance, decreases delays and technical failures. The conclusion from the literature review is that partnering in railway maintenance is considered successful. With accurate knowledge about railway assets the incentive plan becomes accurate which reduces costs.

    The literature review is a part of a research project with an overall goal to develop a model to guide the selection of appropriate type of procurement strategy, contract and control of maintenance for a moresustainable railway system.

    Emil och Ida i Lönneberga2016Övrigt (Övrigt vetenskapligt)
    Abstract [sv]

    En tecknad film skapad av Pennfilm med Per Åhlin, Alicja Björk och Lasse Persson som regissörer. Filmen består av tre historier av Astrid Lindgren med karaktärerna Emil och Ida i Lönneberga. Astrids egen röst används. 

    Filmen är producerad av Filmlance International AB och fick 8 miljoner i produktionsstöd från Svenska Filminstitutet. Den distribueras av SF Film och finns tillgänglig på flera plattformar. Första gången var biopremiär 25 december 2013. Den senaste plattformen var visning i SVT med påföljande tid tillgänglig i SVT Play under hösten 2016.

    Evaluation of Live Loudness Meters2019Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Discrepancies in loudness (i.e. sensation of audio intensity) has been of great concern within the broadcast community. For television broadcast, disparities in audio levels have been rated the number one cause to annoyance by the audience. Another problem area within the broadcast and music industry is the loudness war. The phenomenon is about the strive to produce audio content to be at least as loud or louder to any other audio content that it can easily be compared with. This mindset, when deciding for audio level treatment, inevitably leads to an increase in loudness over time, and also, as a technical consequence, a decrease of utilized dynamics. The effects of the loudness war is present in both terrestrial radio transmissions as well as in music production and in music distribution platforms.

    The two problems, discrepancies in loudness and the loudness war, both emanate from the same source; regulations of audio levels and the design of measurement gear have not been amended to cope with modern production techniques. At the time when the work on this thesis started, the ruling technical recommendations for audio level alignment were based on peak measurement. This measured entity has poor correspondence to loudness. To counter the above described problems, the European Broadcasting Union (EBU) and the International Telecommunication Union (ITU) has developed new recommendations for audio alignment, EBU R 128 and ITU-R BS.1770. The new definitions for loudness measurement constitutes simplified models on the human perception of audio intensity. When using the new recommendations in production, the problems have been shown to diminish.

    For an engineer in a live broadcast scenario, measurement equipment also need to be updated in real-time to illustrate a time-variant loudness of the signal. EBU and ITU also has regulated how this type of measurement gear should behave. EBU Tech 3341 and ITU-R BS.1771 define properties for live loudness meters. These recommendations has since the time of publication been implemented in measurement equipment from manufacturers and become available in production facilities.

    This thesis investigates the conceptions that have led up to the present recommendations for live loudness meters. It maps out the (at the time) present ways to evaluate the same. Emanating from this knowledge, a new methodology to evaluate loudness meters is proposed that combines qualities from former methods to achieve an alternative balance between ecological validity and control in the experiment design. The methodology includes a procedure to capture data from engineers’ actions and the resulting audio levels from simulated broadcast scenarios. The methodology also incorporates a way to process this type of data into different parameters to be more accessible for interpretation. It presents an approach to model the data, by the use of linear mixed models, to describe different effects in the parameters as the result of the meters’ characteristics. In addition, a review on publications that examine the engineers’ own requests for beneficial qualities in a loudness meter has been condensed and revised into a set of meter criteria that specifically is designed to be applied on the outcome of the mixed models. The outcome of the complete evaluation yields statements on meter quality that are different and complementary to formerly proposed methods for meter evaluation.

    The methodology has been applied in two different studies, which also are accounted for in the thesis. The conclusions from these studies has led to an increased understanding of how to design live loudness meters to be satisfactory tools to the engineer. Examples of findings are: the effect of the speed of the meter, as being controlled by one or several time constants, on the readability of the meter and the dispersion in output levels – some tested candidates, with higher speed than the present recommended ones, has been shown to be adequate as tools; the three-second integration time has been shown to generate a smaller dispersion in output levels than the 400 ms integration time; the effect of the gate in BS.1771 on the resulting output levels– the gate generally leading to an increase in output levels. The acquired knowledge may be used to improve the present recommendations for audio level alignment, from EBU and ITU.

    Arena Sports in Stereo Versus Binaural - Rating and Important Attributes2021Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Although a majority of the listening is done on headphones today, most, if not all, televised arena sports is still mixed for loudspeakers. By providing binaural audio for headphones listening, the qualities of surround sound could potentially be experienced on headphones. To find out if this holds true, 13 subjects with experience of critical listening agreed to perform a listening test where they were asked to rate four attributes of which preference is one. To the rating of preference, they also had to argue for their thinking. Lastly, further attributes and qualities was collected to find what attributes seem to be of greatest importance for rating of arena sports in binaural. The results show no statistical significance when comparing the ratings of the binaural and stereo mix for each attribute, and the sample group is clearly disagreeing what stimuli to rate the highest. The collection of qualitative data gave better results and could be summarized to seven attributes of which four appeared in the data from more than half of the test subject. With this result it is clear that more research is needed to find what the most important aspects of binaural mixing are, and how binaural audio best can be used for televised arena sports.

    Value creation through digital solutions in the energy industry: A case study at Skellefteå Kraft AB2018Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Purpose – The purpose of this master thesis is to gain a better understanding of how value creation can be achieved with digital solutions in the energy industry. More specifically, this research aims to increase the understanding of factors that affect customer value in form of exploring the customers’ digital wants and needs.

    Method – This master thesis uses a combination of exploratory and descriptive approach which is based on qualitative data gathered from semi-structured interviews with area experts and focus groups with customers. In this study three area experts and four focus groups were included. The gathered data were analyzed through an abductive analysis approach and a thematic coding.

    Findings – The research found three main findings that energy company’s need to take into consideration. The first is that the energy industry needs to simplify the energy concept since customers’ state that the industry is too complex at the moment. Second is that value creation can be achieved in form of a superior mobile application where customers’ have the ability to follow their consumption and can gain improved customer care. The last main finding from this study show that there may be a lot of changes in the energy industry in the future, which entails many possibilities for energy companies to improve customer value.

    Recommendations – The recommendations from this study is that energy companies need to address that the driving force to buy in the energy industry is that customers want to like their energy company. The energy industry must change their focus and provide marketing strategies that are appealing to the customers’ emotions. Companies in the energy industry also need to deal with the increasing digitalization that is affecting society everywhere. The development of a great mobile application will improve a lot of things for the customers such as making their consumption controllable and easier to grasp, which will make them more satisfied. It is also recommended that energy companies in Sweden unite and together make a proposition to the EU to drop the regulations on electricity charges in order to unlock energy companies’ ability to make energy subscription customer friendly.

    Research contribution – This master thesis contributes to the three dimensions that customer value derived from, in the energy industry digital solutions affect functional and emotional value but has low impact on social value. It also occurred that simplicity, control, better information and customers’ buy with their heart are key factors that contributes to customer value in the industry, which contributes to both theoretical and practical. Digitalization are also moving fast in the energy industry which companies need to embrace right away and take action to not fall behind.

    Global project alignment and performance: Combining Chinese and Western management practices2018Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Purpose – The research purpose is to add insights to the project management literature by studying a global project encompassing Chinese and Western project participants, to possibly increase the understanding of how project alignment can be achieved.

    Method – The analytical approach for this abductive and explorative study was anchored in a six-phase thematic analysis (Clarke & Braun, 2014). A single-case study approach was used encompassing 17 interviews and 61 days of observations at a multinational manufacturing firm in China. 

    Results - Both Chinese and Western project managers consider project effectiveness and efficiency when evaluating project success. However, there are several key nuances that separate the two groups, as Western project managers focus on customer satisfaction through efficient methods when evaluating project performance, whereas Chinese project managers focus on internal satisfaction through effective methods. The different viewpoints although similar affect the ability of manufacturing organizations to achieve alignment within global projects. To achieve alignment within global projects manufacturing organisations need to focus on three types of alignment while accounting for the nuanced view on project success; objective alignment, role alignment and internal alignment.

    Theoretical implications – Our study proposes an emergent model reducing the complexity of achieving alignment in global projects. The model contains three new types of alignment (objective, role and internal) that are actionable and direct compared to previous alignment types. The alignment types aids in the unification of Chinese and Western project managers view on project success.

    Practical implications – We expand the understanding of the Chinese and Western view on project success and provide insight into how alignment can be achieved in global projects. Our findings suggest that project managers should first achieve objective alignment before addressing role and later internal alignment in efforts to increase project performance.

    NOVA: Verktyg och metoder för normkreativ innovation2016Rapport (Övrig (populärvetenskap, debatt, mm))
    Abstract [sv]

    Alla är sig själv närmast. Och vi gör oftast som vi är vana att göra. Vi styrs av de normer och värderingar som har format oss - även om vi tror att vi är innovativa. Resultatet riskerar att bli lösningar som diskriminerar och begränsar. En stor utmaning är att förstå andra människors behov. Om vi kan använda ett normkritiskt perspektiv och se bortom våra egna ramar kan vi nå en större potential inom innovation. Men att förverkliga den potentialen är lättare sagt än gjort. Det krävs vad vi kallar normkreativitet. Normkreativitet bygger på en medvetenhet om att normer och värderingar kan begränsa och diskriminera. Men den kräver också ett analytiskt arbete att undersöka människors verkliga situation och djupliggande behov - och samtidigt ett kreativt arbete att omsätta kritik och kunskap i nya lösningar. NOVA innehåller konkreta verktyg och handfasta metoder för alla som vill skapa sådana normkreativa lösningar. Materialet är baserat på praktiskt erfarenhet och forskning från en mängd olika projekt och studier. Formatet är valt för att gynna kreativitet och samverkan. Fokus är på normer som diskriminerar, men egentligen är innehållet användbart i alla innovationssammanhang. All innovation handlar ju om att utmana normer.

    Does the amount of information displayed in parametric equalizers impact decision making and workflow?2022Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Mixing audio is not only an aural activity, but also, becoming increasingly more visual, and connections between the engineer’s action and interface are not yet fully understood. This study aimed to investigate how different amounts and types of data displayed in parametric equalizers impact mix decisions and workflow. A usability test with audio engineer students were conducted. The test consisted of three different interfaces with variable information displayed and subjects were to perform six common equalization tasks. Two categories of stimuli were used, surgical and aesthetic. The parameters that were measured was effectiveness, efficiency, workflow, and preference. A post session questionnaire was also conducted. Each interface and category were compared and a t-test for each comparison were conducted. Task completion and time for task completion were determined and calculated. Eight t-tests were also conducted between interfaces. Parameters adjusted, order of adjustment, and most used parameter were determined. Preference ratings were categorized and analyzed. The results show that the EQ with graphic display performed better for the surgical category. Significant differences were also found for the surgical category between interfaces with most dissimilarities. The workflow tended to alternate between interface designs. The preference rating showed a clear preference for the interface with graphic display.

    Design of a Test Equipment: Quality Control on Hydraulic Quick Couplings Used in the Excavation Industry2020Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Byggmaskiner använder snabbfästen för att snabbt byta det fastsittande verktyget. Redskapet låter maskinföraren styra på- och avkopplingen av verktyget från insidan av hytten. Detta sparar tid och gör konstruktionsarbetet mycket enklare för dem som jobbar. Snabbfästet används oftast på grävmaskiner, placerade längst ut på grävmaskinsarmen. Verktyget som snabbfästet ansluter till måste vara utrustad med en fastsvetsad grind för att kopplingsprocessen ska fungera. Både snabbfästet och grinden är utrustade med hydrauliska snabbkopplingar, honhalvorna i snabbfästet och hanhalvorna i grinden. De ansluter hydrauliken från maskinen till verktyget. Detta examensarbete inom teknisk design fokuserar på att utveckla en testutrustning som kan säkerställa kvaliteten på hydrauliska snabbkopplingar. Projektet utförs i samarbete med företaget Steelwrist, som begär att utrustningen ska upptäcka läckage i kopplingarna, både i anslutet och ej anslutet tillstånd, samt att mäta de interna friktion- och fjäderkrafter som uppstår under anslutning och frånkoppling.

    Projektet bestod av fyra faser, inspirerad av design processen 'the double diamond process'. De fyra faserna omfattar totalt tre sekvenser innehållande en divergerande del och sedan en konvergerande del i form av att först utforska brett, följt av att smalna av med mer fokuserat besluttagande. Fokus i den första fasen var att ta reda på information om säkerhet, kvalitet, mätningar och instrument, tillsammans med intervjuer och observationer för att förstå det aktuella tillståndet på företaget. I den andra fasen definierades specifikationer och arbetsflödet för den nya testutrustningen. I följande fas inleddes utvecklingen av testutrustningen. Först genom att generera hundratals potentiella lösningar på delfunktioner, som sedan kunde delas in i fem koncept som parallellt utvecklades och utvärderades. I den sista fasen färdigställdes det bästa av de fem koncepten och konstruerades i CAD så modeller och ritningar på den slutliga designen kunde levereras.

    Huvudfokuset i utvecklings- och utvärderingsprocessen har varit att skapa en så säker produkt som möjligt. De positioner som utförs av operatören undersöktes grundligt och ergonomin prioriterades högt. En annan viktig faktor var enkelheten i testutrustningens olika komponenter.

    Projektet resulterade i en komplett lösning för en ny teststation, bestående av lager för adaptrar, reservdelar och dokument, tillsammans med testutrustningen i form av en markplacerad maskin. Testutrustningen försluter den hydrauliska snabbkopplingshalvan, som är tänkt att testas, mot en adapter med en pneumatisk cylinder. En servomotor flyttar sedan motsatt snabbkopplingshalva för att möjliggöra anslutning och frånkoppling. Den sistnämnda kopplingshalvan är fäst på en lastcell som mäter krafterna som uppstår. Det befintliga läckagedetekteringsinstrumentet är anslutet till testutrustningen för att fylla testobjektet med luft i dem olika tillstånden.

    Constituting gender and gender equality through policy: the political of gender mainstreaming in the Swedish forest industry2018Ingår i: Equality, Diversity and Inclusion, ISSN 2040-7149, E-ISSN 2040-7157, Vol. 37, nr 8, s. 763-779Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose

    In Sweden, gender mainstreaming policies have a long political history. As part of the national gender equality strategy of the Swedish forest industry, the ten largest forestry companies committed themselves to gender mainstream their policies. Limiting the impact of policies and the agency of change, the purpose of this paper is to focus on the varied and conflicting meanings and constitution of the concepts, the problem and, in extent, the organisational realities of gender mainstreaming.

    Design/methodology/approach

    In both, implementation and practice, gender mainstreaming posse challenges on various levels and by analysing these documents as practical texts from the WPR-approach. This paper explores constructions of gender and gender equality and their implications on the practice and the political of gender mainstreaming in a male-dominated primary industry.

    Findings

    The results show that the organisations themselves were not constituted as the subject of the policy but instead some of the individuals (women). The subject position of women represented in company policy was one of lacking skills and competences and in the need of help. Not only men and the masculine norms but organisational processes and structures were also generally invisible in the material. Power and conflict were mainly absent from the understanding of gender equality. Instead, consenting ideas of gender equality were the focus. Such conceptualisations of gender equality are beneficial for all risk concealing power structures and thereby limit the political space for change.

    Originality/value

    By highlighting the scale of policy and the significance of organisational contexts, the results indicate how gender and gender equality are constitutive through the governing technologies of neoliberal and market-oriented ideologies in policy – emphasising the further limiting of space for structural change and politicalization within the male-dominated organisations of Swedish forest industry.

    Abstract [sv]

    I debatten om Sveriges prestationer när det gäller innovation och entreprenörskap blandas lovord med domedagsprofetior. Det pratas bland annat om svenska paradoxer och entreprenöriella klimatförändringar, men utifrån en rad olika källor och definitioner. I denna rapport reder nio forskare, från de tre ledande innovationsforskningscentrumen CESIS, CiiR och CIRCLE, ut begreppen. De levererar en nyanserad bild av Sverige som innovations- och kunskapsnation.• Hur står sig ”det nya Sverige” i en internationell jämförelse?• Existerar den svenska paradoxen?• I vilket land får en investerad FoU-krona störst effekt?• Och är sambandet mellan nyföretagande och innovation alltid positivt?Detta är några av de frågor som får svar.

    Exploring new interaction possibilities for video game music scores using sample-based granular synthesis2020Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    For a long time, the function of the musical score has been to support activity in video games, largely by reinforcing the drama and excitement. Rather than leave the score in the background, this project explores the interaction possibilities of an adaptive video game score using real-time modulation of granular synthesis. This study evaluates a vertically re-orchestrated musical score with elements of the score being played back with granular synthesis. A game level was created where parts of the musical score utilized one granular synthesis stem, the parameters of which were controlled by the player. A user experience study was conducted to evaluate the granular synthesis interaction. The results show a wide array of user responses, opinions, impression and recommendations about how the granular synthesis interaction was musically experienced. Some results show that the granular synthesis stem is regarded as an interactive feature and have a direct relationship to the background music. Other results show that interaction went unnoticed. In most cases, the granular synthesis score was experienced as comparable to a more conventional game score and so, granular synthesis can be seen a new interactive tool for the sounddesigner. The study shows that there is more to be explored regarding musical interactions within games.

    Ökad effektivitet inom lastningsprocesser: En fallstudie enligt DMAIC vid Viking Malts lastningsprocesser av malt2020Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Effektivitetsparadoxen, där flödeseffektivitet vägs mot resurseffektivitet, är en utmaning sominnebär en balansgång mellan resursers värdeadderande tid och flödesenhetersvärdemottagande tid. Viking Malt, ett av Europas största mälterier, är ett företag som tampasmed detta ställningstagande. Examensarbetet är genomfört vid deras produktionsanläggning iHalmstad där effektivitetsproblem uppdagats som en konsekvens av långa och varierandecykeltider i lastningsprocesser. Implikationerna blir försvårad planering och nekande avtilläggsbeställningar, varpå ytterligare kundsamarbeten uteblir. Dessutom finns ett missnöjebland de anställda som berör icke-ergonomiska arbetsmoment, vilket kan hämma effektivitetoch arbetssäkerhet.

    Syftet med examensarbetet har därför varit att utreda och ta fram rekommendationer för hurViking Malt kan arbeta för att effektivisera lastningsprocesserna. Dessutom förväntas arbetetbidra med ökad processkännedom samt förbättrad ergonomi och säkerhet. Syftet har uppnåttsgenom ett Sex Sigma projekt där problemlösningsmetodiken DMAIC tillämpats. Underexamensarbetets gång inriktades arbetet alltmer mot den lastningsprocess i vilken malten fyllsdirekt i en container, i rapporten benämnd loading (container).

    Examensarbetet har genom analyser av observationer, intervjuer och sekundärdata kunnatidentifiera faktorer som orsakat ett ojämnt flöde och icke-ergonomiska arbetsmoment.Förbättringsförslag har därför utformats för att motverka problematiken. Förslagen som beröreffektivitetsförbättringar har simulerats i syfte att validera dess trovärdighet och bidra medrealistiska kalkyler.

    En åtgärdsplan med lösningsförslag till icke-ergonomiska arbetsuppgifter och ineffektivalastningsprocesser har upprättats, vilket förutspås gagna fallorganisationens fortsattaförbättringsarbete. Konceptuellt framtogs ett ergonomiförbättrande verktyg som förväntasförbättra arbetsmiljö och ergonomi. De ekonomiskt kvantifierbara förslagen beräknas ökalastningskapaciteten med drygt 10,5 procent, vilket motsvarar en ökad bruttovinst med 1 047500 kronor årligen.

    Reuse of manufacturing experience in product and process definitions2008Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Today's manufacturing industry faces hard competition, both in the form of competitor's low cost outsourcing and to reduce labour cost. Increased public consciousness for environmental pollution and stricter government legislation are also drivers for a more efficient product development process and companies competing on the global market must continue to improve there methods and tools to gain an advantage. The company's intellectual properties and the ability to capitalize on experience from earlier projects becomes a key factor when competing on the global market. This thesis work explores the mechanisms for knowledge reuse and suggests methods and tools involved in the product development process to improve the use of manufacturing experience in order to prevent manufacturing flaws to reoccur in new product development programs. The research is carried out in a project funded by the Swedish research agency VINNOVA together with the industry, through the MERA program. The project aims to improve the Digitally Linked Process and has a focus on Experience reuse. An initial research question was formulated to address the problem and guide the research towards a better understanding; "How can experience from manufacturing processes be tied and reused to impact the definition of governing product and process definition?" A study was set up to investigate the current practices and to aid the research in formulating an approach to improve methods and tools for Reuse of Manufacturing Experience (RoME). The study was conducted at two companies, one in the aerospace industry and one in the automobile industry. The "How" and "Why" questions supported a case study approach The study provided a better understanding of the problem and pointed at a number of opportunities to increase the use of manufacturing experience. One of the findings pointed out in the survey was the lack of a working process for preventing recurrence of a bad design in manufacturing. Furthermore, the study revealed a potential improvement in the use of capability data and problem reports that are captured and stored in databases, today more or less solely used in manufacturing. A new research question was formulized as the improvement of the RoME process where set in focus; "How can the process of experience reuse from manufacturing phases be improved to better impact earlier phases in product development?" The current process for finding and accessing process capability data from a Design Engineering perspective were investigated and described as well as the process to retrieve problem report notifications regarding specific design features of a component. The process where found to be both time consuming and tedious, and as a result of that, seldom used by design engineers. Key enablers having a significant impact on the RoME process where identified. The ability to find and access experience captured in the manufacturing phase. The ability to provide data in a context familiar for the receiver in order to facilitate the learning process. An improved process for reuse of manufacturing experience is proposed and includes methods and techniques to target system integration for search and access. A service oriented product life cycle management (PLM) architecture is proposed as a mean to address the topic of finding and accessing manufacturing data. The standard for PLM Services 2.0 provided by the Object Management Group (OMG) and the increased maturity of web service technology provide the possibility to integrate knowledge rich engineering application in a dispersed heterogeneous system environment. The ability to provide data in a context that is familiar to the receiver is addressed by developing a web based graphical user interface (GUI). The web based GUI presents the manufacturing data in a design context where manufacturing process capability data and problem report notifications are presented in a component view. This supports the design engineer when searching for relevant experience from earlier projects by associating the process capability data and problem reports to a specific design feature, e.g. a flange, and how it relate to the manufacturing process. A web based application is developed to demonstrate the concept. The application presents the product assembly (bill of material) together with the manufacturing process activities and corresponding process capability data in the same view, providing a contextual environment that is tailored for the receiver.

    Support for re-use of manufacturing experience in product development: from an aerospace perspective2011Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Globalization, public environmental concern and government legislation are challenging the Swedish industry to be more efficient and increase its efforts in research and in the development of methods and tools for product development and production. Furthermore, the manufacturing industry is changing from producing solely hardware products towards the inclusion of services or soft offers to add more value for the customer. As a result, there are an increased number of stakeholders involved in the early phases of product development that has an interest in the products design and performance during its life cycle. This challenges the way we manage and share experience internally as well as between companies.The intellectual property of a company is a key asset when competing on the global market; hence, the ability to capitalize on experiences from a company’s development processes as well as products in use becomes increasingly important. Also, the European manufacturing industry and the EU commission conclude that the industry has to move from being "Resource-based" to "Knowledge based" to add more value and avoid competing solely on low-cost. It is recognized that an expensive manufacturing solution has a negative effect on a products total life cycle cost and the ability to earn profit. Hence, manufacturing processes is constantly a target for improvement efforts and experience gained in manufacturing has a potentially high impact on design decisions in new projects.The aim of the research presented here is to improve manufacturability and avoid reoccurrence of design flaws in ongoing or new projects. The research has provided a better understanding of the mechanisms for experience re-use and developed methods and tools for feedback of experience from the manufacturing phase back to the earlier phases in the products life cycle. The work has been carried out within two projects funded by the Swedish governmental agency for Innovation Systems and industry. The first project was DLP-E, Digitally Linked Processes with a focus on Experience re-use and the second project was Robust Machining, aiming for more robust machining processes within manufacturing.The research approach has been to combine the design research methodology and participatory action research. These methodologies together with an initial research question have guided the work:RQ: “How can experience from manufacturing processes be tied and reused to impact the governing product and process definition?”Branches within engineering research committed to his area are concurrent engineering and design for manufacturing although this has usually been limited to general rules of thumb and qualitative methods for designers. Recently however, statistical methods such as Design for Six Sigma and other methods for Robust Design are introduced to affect earlier phases of PD to achieve improved manufacturability.Knowledge Based Engineering (KBE), represents a technology that provide the means to capture and automatically re-use engineering knowledge in an engineering design environment. Methods and tools from this area have been used as an initial approach in this research. A functional product perspective puts a focus on the activity where the product is used rather than on the tangible product itself. From an experience feedback perspective, experience is gained during these activities and possibly re-used if there is a learning process.This thesis presents an initial descriptive case study at two manufacturing companies that provided a better understanding of current practices for experience re-use and identified factors that influenced the feedback of manufacturing experience in product development. Based on initial assumptions and the results from the first descriptive study, a theory on the mechanism for experience feedback and requirements on a manufacturing system was formulated in a prescriptive study. A second descriptive study utilized a prototype to identify if the theory was applicable in an industrial environment and if it addressed the factors it was supposed to address. The research has been an iterative process, whereas results from the descriptive studies have influenced new prescriptive studies, delivering methods and tools, which in turn have influenced the ongoing work at the company where the research was conducted.The main contribution from the research is a framework to support re-use of manufacturing experience. The framework decompose the multifaceted task of experience re-use by identifying typical activities involved in the feedback process and categorizing the “elements of experience” in terms of knowledge, information and data. Combined with an engineering process improvement approach, processes are streamlined and value is added to the product. KBE techniques are used to capture and re-use product and process knowledge in an integrated manner. The applicability of the result has been validated in descriptive studies as well as within company improvement efforts.The research supports a frontloading approach in product development by enabling manufacturing experience to have an impact on the design definition in the early phases of product development. As a consequence, the risk for costly re-design later on in a project is reduced.

    Abstract [en]

    The ability to capitalize on company knowledge and experience earned in various projects is recognized as key assets in the competition on the growing global market. Methods and tools are constantly evolving, still there is a frustration over repeated design flaws and design engineers has a difficult task to find and use manufacturing experience from earlier projects. This paper outlines a process improvement approach where the engineering process is described andanalysed to find bottlenecks. Examples from other engineering processes are presented along with a prototype of a knowledge application to resolve identified issues with the manufacturing feedback process.Experience and knowledge are closely related, hence a knowledge life cycle explain the different stepswith a "capturing" and "deploying" side.The feedback processes for manufacturing experience is analysed where search & find together with contextualisation of experience data are recognised as key mechanisms. A knowledge application is presented that presents experience data from different repositories in a way that is logic for the receiver. This reduces the lead-time and increase the quality of the feedback process.

    Manufacturing system to support design concept and reuse of manufacturing experience2008Ingår i: Manufacturing systems and technologies for the new frontier: the 41st CIRP conference on manufacturing systems / [ed] Mamoru Mitsuishi; Kanji Ueda; Fumihiko Kimura, London: Encyclopedia of Global Archaeology/Springer Verlag, 2008, s. 137-140Konferensbidrag (Refereegranskat)
    Abstract [en]

    Life cycle responsibility for manufacturing companies increases the service content coupled to the product. One consequence is that transferring knowledge gained from all life cycle phases has an even more decisive impact on the definition of the product concept, here referred to as the functional product. The paper focuses on transferring experiences from the manufacturing phase and how to account for these in the design phase. Based on an empirical study at two companies, an automotive and one aeronautical company, current practices were identified. Manufacturing experiences are captured and managed in a manufacturing context whereas the use of experience in the design phase is discussed. Finally a generic approach to support the use life cycle experiences in earlier phases of product development is suggested, where the design and manufacturing case serves as an example.

    Reuse of manufacturing experience to support development of product/service systems2010Ingår i: Industrial product-service systems (IPS²): proceedings of the 2nd CIRP IPS² Conference [2010, Linköping, 14-15 April] / [ed] Tomohiko Sakao, Linköping: Linköping University Electronic Press, 2010Konferensbidrag (Refereegranskat)
    Abstract [en]

    The ability to learn from ongoing and previous projects is important for companies to become, and maintain, competitive. Hence efficient methods and tools for both capturing and reusing experience in all life cycle phases of the product is a key enabler to keep and gain an advantage in product development companies. By definition, PSS combines "features" applicable to different life cycle phases, e.g. reusability when disposed, serviceability in aftermarket, manufacturability in manufacturing, etc. The "total offer" must take into account all aspects and coherently map these into a receiver context to support the design engineer in his work. In particular - the design phase is important since both the products, its realization and accompanying services are to a large extent decided in the early phases. This paper presents an industrial case demonstrating the mapping and contextualization of manufacturing experience to provide engineers relevant context when defining and designing the PSS

    A case study of how knowledge based engineering tools support experience re-use2011Ingår i: Research into Design: Supporting Sustainable Product Development / [ed] Amaresh Chakrabarti, Bangalore, India: Research Publishing Services, 2011Konferensbidrag (Refereegranskat)
    Abstract [en]

    A manufacturing company’s unique intellectual capital is to a largeextent built on experience from its own product development andmanufacturing processes. Thus, methods and tools to utilize and benefit fromthis experience in an efficient way have an impact on a company’s ability tostay competitive and advance on the global market. Knowledge BasedEngineering (KBE) is an engineering methodology to capture engineeringknowledge systematically into the design system. Hence, KBE tools areconsidered to support experience re-use and improve engineering activities.This paper presents the results from a study where the objective was toinvestigate the support for experience re-use in KBE applications in anaerospace company. A proposed framework is presented to analyze thecapturing and use of experience in a company’s processes identifying gaps andpropose improvements. The study revealed weaknesses in the process steps forexperience feedback which can be used to improve KBE applications further.

    Project: Robust Machining2010Övrigt (Övrig (populärvetenskap, debatt, mm))
    Abstract [en]

    New generations of environmentally friendly and safe vehicles require manufacturing of light weight materials with higher strength and, as a consequence, tougher machining conditions and increased machining robustness. There is a lack of practical and reliable methods and tools to meet these challenges in the automotive industry. The very complex system of machine tool, fixture, cutting tools and the machined part is almost impossible to model without complementary measurements of the real system at the factory floor in full production. Using Virtual Engineering together with studies of machining processes the project team will assess these challenges.

    Can a Dry Recording Treated with a Convolution Reverb in a Surround Sound Speaker System be Perceived as Maintaining the Same Degree of Naturalness as Real Recorded Reverberation?2023Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    When recording classical instruments, access to a physical space of acoustic properties associated with classical music might not always be available. This study seeks to investigate if classical music recorded in an environment with a short reverberation time can be treated with an impulse response from a concert hall and still maintain the same sense of naturalness. The study is broken down into three phases of analysis. Phase one seeks to analyze to what extent people can tell the difference between the two reverberation types: real recorded reverberation and convolution reverb. Phase two analyses if people perceive the amount of naturalness to be different between the two reverberation types. Phase three analyses the potential influence that certain spatial or timbral attributes might have on perceived amount of naturalness. Samples for the listening test were recorded in a studio, and in a classical concert hall where the impulse responses also were created. A two-part listening test (pre-study and main study) was conducted utilizing a 5.1 surround sound speaker system. The results showed that the convolution reverb could replace the real recorded reverbation to a small- to fair degree, and still maintain the same sense of naturalness.

    Processes in collaborative entrepreneurship: a longitudinal case study of how multiple actors exploit a radically new opportunity2014Ingår i: The International Entrepreneurship and Management Journal, ISSN 1554-7191, E-ISSN 1555-1938, Vol. 10, nr 4, s. 713-726Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this longitudinal case study, the authors integrate the theory on social movement with the entrepreneurship literature on opportunity discovery, evaluation, and exploitation. They construct a model on collaborative entrepreneurial processes in which multiple partners are involved in identifying, forming, and exploiting an opportunity. Three interdependent subprocesses are identified: (1) the opportunity conceptualization dialogue, (2) resource mobilization and, (3) legitimacy building, which significantly contribute to our understanding of how individuals across different organizations become engaged in collaborative entrepreneurial processes. The model of collaborative entrepreneurial processes complements traditional models of the entrepreneurial process, which place the individual entrepreneur at the center of the process and does not consider group mobilization processes in which the actors aim to be creative and innovative in collaborating with actors from other organizations or firms.

    Corporate venturing deal syndication and innovation: the information exchange paradox2011Ingår i: Long range planning, ISSN 0024-6301, E-ISSN 1873-1872, Vol. 44, nr 2, s. 134-151Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Many incumbent corporations make equity investments in young technological start-ups to enhance their innovation effectiveness, and the great majority syndicate at least some of their investments with other incumbents. While syndication is generally held to benefit incumbent corporations, this study demonstrates that it may also be detrimental to corporate innovation, by elaborating the notion of an information exchange paradox - essentially, that information exchanges within CVC networks must, somehow, be both open and closed at the same time. Corporations must try to appropriate the knowledge championed by their investees and fellow-investors, but also protect their own know-how from leaking to competitors. Unlike prior CVC research, we demonstrate that knowledge sharing in open innovation forums may be counterproductive. Using a unique data set of the investment decisions made by 163 corporations over four years we show that, for some, participating in syndicate networks may involve losses that outweigh their gains. Our analysis establishes two key findings. First, corporations need to consider the trade-off between the number of ventures they support and the position they take in their syndication networks. The best strategies appear to be maximizing isolationist (supporting many ventures but staying away from the network centre) or minimizing centralist (supporting few ventures, but occupying a central network position) - the other two options (maximizing centralist and minimizing isolationist strategies) are far less effective in converting CVC investments into corporate innovation. Second, this picture is particularly applicable to highly concentrated industries dominated by several powerful incumbents: in fragmented industries these strategy differences are far less pronounced, so the choice of CVC syndication strategy will depend on other considerations. This supports a contingency view of syndication, implying that ensuring incumbent corporations really benefit from equity investments in start-ups is a not a trivial task for their managers

    Technological Advancement through Imitation by Industry Incumbents in Strategic Alliances2013Ingår i: Uddevalla Symposium 2013.

    Abstract [en]

    Contrary to the conventional wisdom, this study demonstrates that technological laggards and not industry front-runners are most likely to experience high rates of technological advancement in strategic alliances. We further suggest that imitation and not innovation is the primary source of such advancement based on the fact that technological progress by laggards is most visible in industries that lack strong appropriability regimes. Finally, we present empirical evidence suggesting that lagging established corporations prefer to imitate from startups and not from fellow-incumbents. These results are derived from a careful analysis of a longitudinal sample of over 150 incumbents with varying degree of technological prowess who engage in partnerships with both startups and fellow-incumbents across a wide representation of industries. Our paper contributes to technological innovation, strategic alliance, entrepreneurship, and imitation literatures and provides non-trivial implications for startups.

    Corporate venture capital: The role of governance factors2016Ingår i: Journal of Business Research, ISSN 0148-2963, E-ISSN 1873-7978, Vol. 69, nr 11, s. 4744-4749Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Research on corporate venture capital (CVC) has consistently proven its importance for innovation and other strategic goals, yet information on the antecedents of CVC activity is scarce. This study provides theoretical arguments for the role of governance factors including board, CEO, and institutional ownership characteristics. Empirical evidence from an international sample of global CVC investments shows that factors such as having a board with multiple board mandates and institutional ownership are important factors for CVC activity. The conclusion is that the role of governance factors is important, and that subsequent research should not ignore this group of factors.

    Abstract [en]

    Entrepreneurs respond to opportunities that come in two basic forms: innovation and arbitrage. This article presents a technique called the minimum performance inefficiency (MPI) estimation method that could be used to estimate arbitrage opportunities. The technique has several advantages over the conceptually similar data envelopment analysis (DEA) and other techniques. The authors validate the technique with a well-known data set and illustrate its use based on secondary data from the publishing industry.

    Start-up rates and innovation: A cross-country examination2012Ingår i: Journal of International Business Studies, ISSN 0047-2506, E-ISSN 1478-6990, Vol. 43, nr 1, s. 41-60Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Despite the widespread assumptions of the positive relationship between start-up rates and innovation, the empirical support for this conjecture in the crosscountry context is largely lacking. We draw upon recent advances in the entrepreneurship literature to propose that the relationship between start-up rates and innovation is not uniformly positive, as expected by the early scholars of entrepreneurship, but instead depends on the country's stage of development. The relationship is positive in the developed countries, but negative in countries in early development stages. On balance, there is a weak negative association between start-up rates and innovation. We test our hypotheses on a multi-source dataset that covers 35 countries over the period from 1996 to 2002. The relationships are robust to the choice of three moderators and two dependent variables, as well as a number of post-hoc tests. Our findings indicate that broad-strokes policy efforts that aim at promotion of entrepreneurship as a means to boost country innovativeness may be misguided, and instead suggest a contingency approach.

    Technological arbitrage opportunities and interindustry differences in entry rates2014Ingår i: Journal of Business Venturing, ISSN 0883-9026, E-ISSN 1873-2003, Vol. 29, nr 3, s. 437-452Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this study we investigate the relationship between technological arbitrage opportunities and entry rates in twenty-six industries over the course of five years. Arbitrage opportunities are shown to be a positive and significant predictor of business entry rates. Such positive effect is weakened in industries with strong appropriability regime including effective patents, secrecy, and lead time. Adding arbitrage opportunities to the typical determinants of entrepreneurship such as innovative opportunities significantly increases predictive power of the regression models.

    Operationalizing opportunities in entrepreneurship research: use of data envelopment analysis2011Ingår i: Small Business Economics, ISSN 0921-898X, E-ISSN 1573-0913, Vol. 37, nr 1, s. 39-57Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Despite the impressive development of substantive theories in entrepreneurship, without the development of measurement theories, further advancement of the field is problematic. In particular, the notion of opportunities, central to entrepreneurship research, requires adequate macro-level operationalization. We demonstrate how to employ data envelopment analysis (DEA) to operationalize not only innovative opportunities, but also technological arbitrage opportunities. We provide an illustrative example based on a sample of 66 countries during the period of 1993-2002. We include estimates of innovative and arbitrage opportunities for possible use by other scholars, discuss the promise and limitations of such estimates, demonstrate how both innovative and arbitrage opportunities correlate with the rates of entrepreneurial activity, and suggest several possible directions for future research.

    A conceptual framework for misfit technology commercialization2011Ingår i: Technological forecasting & social change, ISSN 0040-1625, E-ISSN 1873-5509, Vol. 78, nr 6, s. 1060-1071Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The emerging literature on outbound open innovation has highlighted innovation processes, which presuppose active outward technology transfer to increase firm profits. To contribute to this discourse, our paper goes beyond the emphasis on core-related technologies and knowledge that currently dominates the technology management literature and develops the novel concept of misfit technology. This concept captures technologies that are not aligned with a focal firm's current knowledge base and/or business model, but which may still be of great value to the firm if alternative commercialization options are considered. By developing a framework that acknowledges (1) Sources of misfit technology, (2) Environmental uncertainty, (3) Organizational slack, (4) Industry appropriability regime and (5) Technological complexity, we theorize on how different modes of commercialization relate to misfit technology commercialization success. The paper is conceptual and is presented with the purpose to spawn further research on this important topic, but simultaneously touches upon the issues of utmost relevance to R&D management practice
