    Towards New Levels of Creating/Improving and Understanding Value in Swedish Municipalities: A Review of Research on Understanding and Creating Value in Municipal Quality Development by Qualitative Approaches (and Co-Creation)2017Conference paper (Refereed)
    Abstract [en]

    Purpose

    Quality management and Lean initiatives are currently widespread in the Swedish municipal sector. It is also made clear that all Lean initiatives should be initiated to benefit the customer and not for internal organizational reasons. However, the practices currently used for understanding value creation in the municipalities tend to focus heavily on the use of numerical, quantitative approaches. In sharp contrast, the growing field of, for example, design thinking argue that qualitative approaches are key when it comes to getting closer to the citizens, establishing new levels of understanding and thereby inspiring new and better solutions. In sum, it seems likely that municipalities are struggling with developing quality due to relying, in too one-sided on the use of quantitative rather than qualitative approaches to understand and spark new levels of value creation. The purpose of this paper is to contribute with a review of research concerning qualitative approaches for understanding and co-creating value in municipal quality development.

     

    Methodology/Approach The paper is based on a literature review.

     

    Findings The paper provides an overview of previous research concerning practices for evaluating and understanding value creation in the context of a municipal quality development.

     

    Value of the paper

    This overview is of value for practitioners within the context, as well as researchers that wants to contribute within this area.

    Hydra Coupler: Snabbkoppling till protessystem2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Många amputerade upplever att deras protessystem inte är lika anpassningsbara som de hoppats på. Dagens protes­system är utformade med låsta komponenter vilket begrän­sar användarens möjlighet att anpassa systemen till specifika ändamål. Därför påbörjades ett projekt med målet att under­söka om det finns möjlighet att skapa en snabbkoppling till protessystem genom att framställa ett konstruktionsförslag av ett lösningsalternativ. I starten av projektet påbörjades en problemformulering för att undersöka om problemen uppvisade några beroenden eller påverkade andra poster inom det framställda flödesschemat. Efter genomförd problemformulering påbörjades förstudierna för att samla in relevant information till genomförandet av projektet, där förstudien genomfördes med hjälp av en konkurrensanalys, funktionsanalys och enkätundersökning. Efter att förstudien var avklarad påbörjades en designprocess för att framställa ett konstruktionsförslag av ett lösningsförslag. Under designprocessens start formulerades en kravspecifikation så att konstruktionsförslaget hade något att förhålla sig till, och sedan påbörjades modelleringen av ett konstruktionsförslag med hjälp av Solidworks. En prototyp framställdes i plast med hjälp av en 3D- printer för att kontrollera passform av ingående komponenter och slutligen så undersöktes konstruktionsförslagets hållfasthet i Solidworks med hjälp av hållfasthetssimuleringar. Genomförandet av projektet har resulterat i en framställning av konstruktionsmaterial, prototyp, konstruktionsritningar till ett konstruktionsförslag av en snabbkoppling till protessystem. Konstruktionsförslaget kallat Hydra Coupler förser protesanvändare med möjligheten att enkelt byta proteskomponenter efter ändamål utan behov av externa verktyg, och Hydra Coupler kan även inneslutas av kosmetik utan att förlora funktionalitet.

    Roller skis' rolling resistance and grip characteristics: influences on physiological and performance measures in cross-country skiers2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The aim of this thesis was to investigate roller ski characteristics; classical and freestyle roller skis’ rolling resistance coefficients (μR) and classical style roller skis’ static friction coefficients (μS), and to study the influence of different μR and μS on cross-country skiers’ performance and both physiological and biomechanical indices. The aim was also to study differences in skiing economy and efficiency between recreational skiers, female and male junior and senior elite cross-country skiers.The experiments showed that during a time period of 30 minutes of rolling on a treadmill (warm-up), μR decreased significantly (p<0.05) to about 60-65 % and 70-75 % of its initial value for freestyle and classical roller skis respectively. Also, there was a significant influence of normal force on μR, while different velocities and inclinations of the treadmill only resulted in small changes in μR.The study of the influence on physiological variables of a ~50 % change in μR showed that during submaximal steady rate exercise, external power, oxygen uptake, heart rate and blood lactate were significantly changed, while there were non-significant or only small changes to cycle rate, cycle length and ratings of perceived exertion. Incremental maximal tests showed that time to exhaustion was significantly changed and this occurred without a change in maximal power, maximal oxygen uptake, maximal heart rate and blood lactate, and that the influence on ratings of perceived exertion was non-significant or small.The study of classical style roller skis μS showed values that were five to eight times more than the values of μS reported from on-snow skiing with grip-waxed cross-country skis.The subsequent physiological and biomechanical experiments with different μS showed a significantly lower skiing economy (~14 % higher v̇O2), higher heart rate, lower propulsive forces coming from the legs and shorter time to exhaustion (~30 %) when using a different type of roller ski with a μS similar to on-snow skiing, while there was no difference between tests when using different pairs of roller skis with a (similar) higher μS.The part of the thesis which focused on skiing economy and efficiency as a function of skill, age and gender, showed that the elite cross-country skiers had better skiing economy and higher gross efficiency (5-18 %) compared with the recreational skiers, and the senior elite had better economy and higher efficiency (4-5 %) than their junior counterparts, while no differences could be found between the genders.

    Roller ski rolling resistance and its effects on elite athletes’ performance2008In: ENGINEERING OF SPORT 7, VOL 2, 2008, Vol. 11, no 3, p. 393-400Conference paper (Refereed)
    Abstract [en]

    Modern ski-treadmills allow cross-country skiers, biathletes and ski-orienteers to test their physical fitness in a laboratory environment whilst performing classical and freestyle (skating) techniques on roller skis. For elite athletes the differences in performance between test occasions are quite small, thus emphasising the importance of knowing the roller skis’ rolling resistance in order to allow the correct comparison between the results of different test occasions. In this study the roller skis’ rolling resistance has been measured using equipment on the ski-treadmill. The study investigates the influence of significant changes in rolling resistance on physiological variables. The results show that during submaximal exercise, heart rate, blood lactate, power and oxygen uptake are significantly changed by different rolling resistances, while there are no significant or only small changes to cycle rate, cycle length and ratings of perceived exertion. Incremental maximal tests show that time to exhaustion is significantly changed by different rolling resistances and this occurred without significant changes in maximal oxygen uptake and heart rate, and the influence on maximal power and ratings of perceived exertion were insignificant or small.

    Roller ski rolling resistance and its effects on elite athletes’ performance2009In: Sports Engineering, ISSN 1369-7072, E-ISSN 1460-2687, Vol. 11, no 3, p. 143-157Article in journal (Refereed)
    Abstract [en]

    Modern ski-treadmills allow cross-country skiers, biathletes and ski-orienteers to test their physical fitness in a laboratory environment whilst performing classical and freestyle (skating) techniques on roller skis. For elite athletes, the differences in performance between test occasions are quite small, thus emphasising the importance of knowing the roller skis’ rolling resistance in order to allow the correct comparison between the results of different test occasions. In this study, the roller skis’ rolling resistance was measured on the ski-treadmill’s surface using a roller ski rolling resistance measurement system specially produced for this purpose. The study investigated the influence of significant changes in rolling resistance on physiological variables. The results showed that during submaximal exercise, power, oxygen uptake, heart rate and blood lactate were significantly changed by different rolling resistances, while there were no significant or only small changes to cycle rate, cycle length and ratings of perceived exertion. Incremental maximal tests showed that time to exhaustion was significantly changed by different rolling resistances and this occurred without significant changes in maximal power, maximal oxygen uptake, maximal heart rate and blood lactate, and that the influence on ratings of perceived exertion were insignificant or small.

    Rolling resistance for treadmill roller skiing2008In: Sports Engineering, ISSN 1369-7072, E-ISSN 1460-2687, Vol. 11, no 1, p. 23-29Article in journal (Refereed)
    Abstract [en]

    Modern treadmills allow cross-country skiers, biathletes and ski-orienteers to test their physical performance under laboratory conditions using classical and freestyle techniques on roller skis. The differences in performance between tests are quite small for elite athletes, and it is therefore of great importance to control the rolling resistance of the roller skis. Otherwise different physiological tests cannot be accurately compared.

    This study shows that during a warm-up period of  30 minutes the coefficient of rolling resistance (µR) decreases to about 60-65% and 70-75% of its initial value for freestyle and classical roller skis respectively.

    Simultaneous measurements of temperature and µR shows that stabilized rolling resistance corresponds to a certain running temperature for a given normal force on the roller ski.

    Tests were also performed on the influence on µR of normal force, velocity and inclination. Normal forces produced significant influence on µR , while different velocities and inclinations of the treadmill only resulted in small changes in µR.

    The influence of grip on oxygen consumption and leg forces when using classical style roller skis2014In: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 24, no 2, p. 301-310Article in journal (Refereed)
    Abstract [en]

    The purpose of this study was to investigate the influence of classical style roller skis' grip (static friction coefficients, μ S) on cross-country skiers' oxygen consumption and leg forces during treadmill roller skiing, when using the diagonal stride and kick double poling techniques. The study used ratcheted wheel roller skis from the open market and a uniquely designed roller ski with an adjustable camber and grip function. The results showed significantly (P≤0.05) higher oxygen consumption (∼14%), heart rate (∼7%), and lower propulsive forces from the legs during submaximal exercise and a shorter time to exhaustion (∼30%) in incremental maximal tests when using roller skis with a μ S similar to on-snow skiing, while there was no difference between tests when using different pairs of roller skis with a similar, higher μ S. Thus, we concluded that oxygen consumption (skiing economy), propulsive leg forces, and performance time are highly changed for the worse when using roller skis with a lower μ S, such as for on-snow skiing with grip-waxed cross-country skis, in comparison to ratcheted wheel roller skis with several times higher μ S.

    A portable roller ski rolling resistance measurement system2013In: The Impact of Technology on Sport V: Procedia Engineering / [ed] Subic A, Fuss FK, Clifton P, Chan KM., Elsevier, 2013, p. 79-83Conference paper (Refereed)
    Abstract [en]

    Roller skis are used by cross-country skiers, biathletes and ski-orienteers for their snow-free training and in roller ski competitions. Additionally, much of the current sports research into the physiology and biomechanics of crosscountry skiing is conducted indoors on treadmills using roller skis. For elite athletes, the differences in performance are quite small, thus emphasising the importance of knowing the roller skis' rolling resistance coefficient, especially in connection to research and roller ski competitions. The purpose of this study was to develop a roller ski rolling resistance measurement system (P-RRMS) that is portable and therefore useful in different contexts and locations. The P-RRMS was designed as a small treadmill, equipped with roller ski stabilizing lateral supports and a screwed bar for applying different vertical loads on the roller ski. The design uses only one force sensor, with possible measurements of three directions of force and torque around three axes. The weight of the P-RRMS is 100 kg and it is equipped with wheels to facilitate transportation.

    An experimental study to compare the grip of classical style roller skis with on-snow skiing2013In: Sports Engineering, ISSN 1369-7072, E-ISSN 1460-2687, Vol. 16, no 2, p. 115-122Article in journal (Refereed)
    Abstract [en]

    Cross-country skiers use roller skis for their snow-free training with the aim of imitating skiing on snow. Also, exercise laboratories evaluate the biomechanics and physiology of cross-country skiing using roller skis on a treadmill. The roller skis on the market that are constructed for use in the classical style are equipped with a front and a back wheel, one of which has a ratchet to enable it to grip the surface when diagonal striding and kick double poling (static friction). The aim of this study was to investigate static friction coefficients (μS) of ratcheted wheel roller skis, and compare the results to the μS reported from skiing on snow with grip-waxed cross-country skis. Also, a new type of roller ski with a camber and adjustable grip function was evaluated. The results showed that ratcheted wheel roller skis, on a treadmill rubber mat and on dry and wet asphalt surfaces, reached μS values that were five to eight times greater than the values reported from on-snow skiing with grip-waxed cross-country skis. For the roller skis with a camber and adjustable grip function, the μs could be varied from no grip at all up to the level of the tested ratcheted wheel roller skis.

    Classical style constructed roller skis and grip functionality2011In: Procedia Engineering: The Impact of Technology on Sports IV / [ed] Subic A., Fuss F.K., Alam F., Clifton P., Elsevier, 2011, p. 4-9Conference paper (Refereed)
    Abstract [en]

    Roller skis are used by cross-country skiers for snow-free training, with the aim of imitating skiing on snow. The roller skis on the market that are constructed for use in the classical style are equipped with a front and a back wheel, one of which has a ratchet to enable it to grip the surface when diagonal striding and kick double poling.

    A new type of roller ski was constructed with a function which makes it necessary to use the same kick technique as that used on snow, i.e. the ski has a camber that must be pushed down to obtain grip. Its stiffness can be adjusted based on factors that influence grip, i.e. the skier’s bodyweight and technical skiing skills.

    Thus, our aim was to make comparative measurements as regards grip between ratcheted roller skis and the roller ski with a camber and compare with previous published results for grip waxed skis during cross-country skiing on snow.  The measurements were carried out using specially developed equipment, with a bottom plate and an overlying rubber mat of the same type as used on many treadmills and a function for applying different loads and generating traction on the back of the roller ski.

    Design and development of a climatic wind tunnel for physiological sports experimentation2018In: Proceedings of the Institution of Mechanical Engineers, Part P: Journal of Sports Engineering and Technology, ISSN 1754-3371Article in journal (Refereed)
    Abstract [en]

    The aim of this project was to develop a wind tunnel that enables the study of human performance during various types ofsports and physical activities by examining the influence of aerodynamic drag, precipitation, frictional forces and gravitationalforces on uphill and downhill travel on a moving substrate. An overall design for a wind tunnel and working section containinga large treadmill was drafted, followed by computational fluid dynamics simulations of flow conditions to assess thedesign’s feasibility and select from different geometries prior to its construction. The flow conditions in the completed windtunnel were validated using different flows, speeds and treadmill inclinations. Pilot experiments were carried out using across-country skier to investigate the effect of aerodynamic drag on oxygen uptake during double poling and the maximalachieved speed when rolling on a declined treadmill. The purpose was to validate the usefulness of the tunnel. The resultsshowed that flow conditions are acceptable for experiments even in worst-case scenarios with maximal inclined and declinedtreadmill. Results also showed that aerodynamic drag has a significant impact on the skier’s energy expenditure.

    Delaktighetens förutsättningar och begränsningar i förbättringsarbetet2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Participation is an important aspect when it comes to continuous improvements. Participation increases quality and creates support among employees and is a tool for achieving successful quality work. Companies need prerequisites for creating participation, and in successful companies this success is characterized by the creation of participation and motivation among employees. The aim of the study was to describe how production supervisors create opportunities for participation in improvement processes. The method used was a qualitative inductive approach from a life-world perspective. In-depth interviews were conducted with eight production supervisors and qualitative content analysis was used to examine texts to find sentence entetities and categories. Fishbone diagrams were created as a complement to the interviews. The results and the analysis indicated two categories, prerequisites and limitations to create participation in improvement work. This showed that there are difficulties when it comes to interpreting the term participation and even more difficult to specify the tools inuse. In the future it is of great importance to ensure that the research around the creation of participation is in focus.

    Abstract [en]

    This work has been carried out on behalf of Sundsvall Energi AB, with the purpose of establishing a link between Sundsvall Energi AB:s accumulator in Granloholm and the urban network with a temperature base, and using this connection to get a better understanding of their leakage.

    During the project, a literature study and a survey of the company's current system, was conducted to gain an understanding of the system and the mission. The lack of similar work forced me to look at leak detection methods that were relevant even though they did not handle the same area altogether. On the other hand, counselors and staff members assisted in obtaining the information requested and gave advice and tips on aspects of the assignment that had not been included in the report before.

    The model was developed piece by piece during the work period, when no other work was found that could provide a proper framework for the work. The model has proven to be more accurate than its predecessor but also more difficult to implement.

    The thesis has shown how different energy systems can be from each other and how different, the different methods that are available to look and solve problems in the system are. The use of existing meters and instruments is not always reliable or available, and assumptions and occurrences must sometimes be made to get an overview picture and a valid basis.

    Förutsättningar för ett proaktivt arbete i skolan: en systematisk litteraturöversikt av den proaktiva modellen Response to Intervention2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The education system has historically had a reactive rather than a proactive approach to its customers, that is, students' needs and the conditions for achieving the school's goals. A reactive way of working is still the norm, although today we are aware that the effect of reactive improvements is limited. We are in a paradigm shift where the education system seeks to find models that are based on a modern view of quality, which means putting the customer's needs at the center.

     

    The aim of the study is to contribute further knowledge of how we can drive quality improvements, thus increasing customer value within the Swedish education system. The study is conducted with a systematic literature review of articles on the model Response to Intervention. Categorization is based on Bergman and Klefsjö (2012) model for quality development based on customer needs and satisfaction, and Österbergs (2014) structural quality dimension.

     

    The prerequisites for driving quality improvements using the RTI model can be summarized with; competent staff, the right equipment for carrying out and analyzing screenings of the students, as well as time and support for the work. All the values in the quality management model are mentioned in the articles, which allows us to assume that the RTI model can be used to develop quality and create customer value in the school.

     

    It also requires a culture that values measurement and working with data in order for the RTI model to contribute to quality development. Since the US school system, where the RTI model has been applied so far, is more result-oriented than the Swedish, we assume that the US system is more beneficial for the implementation of the model to be successful.

    Kundlojalitet i mindre B2B företag2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Är nöjda kunder automatisk lojala kunder? Det krävs mer än bara en positiv upplevelse av servicekvalitet för att nå hög lojalitet bland sina kunder. Trots att kunderna upplever servicen lika, kan deras bedömning av tillfredsställelse variera p.g.a. olika förväntningar och prioriteringar. Upplevd servicekvalitet och tillfredsställelse är de första faktorer som påverkar lojalitet. Men det krävs också förtroende för såväl företaget som också på individnivån till företagets representanter, innan kunderna vågar binda sig till en relation med en leverantör. Allt detta påverkar relationen, som med tiden kan utvecklas och fördjupas. Det är alltså servicekvalitet, tillfredsställelse, förtroende samt beredskap att binda sig till en relation och relationskvalitet som påverkar lojalitet i olika utsträckning inom olika branscher.

    Den empiriska undersökningen som genomfördes i form av en webbenkät bland kunder hos ett mindre Business-to-Business (B2B) företag visar att segmentering baserad på lojalitet är ett effektivt sätt att skapa förståelse för hur lojala och icke-lojala kunder ser på företaget och deras servicekvalitet. Segmentering baserar på några extra frågor som mäter lojalitet. Trots låg antal svar (17 svar) är resultat enhetlig för varje segment och visar därmed vilka brister som bör åtgärdas.

    Granskning av snabb pyrolys och hydropy- rolys för produktion av bioolja från trärester: Fyra undersökta tillverkningsmetoder med en teknisk och ekonomisk jämförelse2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Världens klimat- och miljöproblem är ett av dagens stora utmaningar samtidigt som alla resurser ska räcka till ett drägligt liv för en växande befolkning. För att klara dessa utmaningar bör bland annat världens energisystem övergå till 100% förnybart, vilket innebär att tillförseln av fossil energi måste fasas ut och ersät- tas. Fossila bränslen är en ändlig resurs jämfört med biobränslen som kan agera substitut för att öka energitillförseln och minska miljöpåverkan. Denna rapport bygger på att utvärdera fyra företag som levererar teknik för att omvandla bio- massa till biokol, bioolja samt biogas genom en pyrolysprocess. Utvärderingen skall resultera i ett beslutsunderlag för en uppdragsgivare som vill producera bioolja från restprodukter i ett sågverk där val av leverantör främst ska utgå ifrån hur mycket bioolja som kan produceras samt med så hög kvalitet som möjligt. De fyra företagen som undersöks är Steeper Energy och Licella som levererar hydrpyrolysteknik samt BTG-BTL och Biogreen som levererar teknik för snabb pyrolys. Rapporten innehåller även en ekonomisk jämförelse mellan de två teknikerna snabb pyrolys och hydropyrolys. Undersökningen har visat att hydropyrolys ger den bästa slutprodukten men att snabb pyrolys är den mest ekonomiskt lönsamma. Steeper Energy anses vara den bästa kandidaten för än- damålet när det kommer till kvalité och kvantitet av produkt samt energieffekti- vitet.

    Abstract [en]

    At   Trelleborg Engineered Coated Fabrics rubber coated fabrics are manufactured.   In order to apply rubber to fabrics it is indispensable to first add a rubber   adhesion to the fabric. At Trelleborg ECF a special calendaring machine is   used for this operation. While it is an effective machine for big production   volumes it is not as effective when new products are developed. Therefore two   new lab machines has been procured so that new products can be developed in   the lab. The intent of this project is to evaluate the new machines, find a   connection between lab and production machines and appraise the factors that   affect the adhesion. This has been done by testing different combinations of   settings in the process when the adhesion is added to the fabric.   Additionally an analysis of the production process has been done to manage   the connection between lab machines and the production machine. Though no   fully complete connection between the machines has been found the factors   affecting the adhesion has been evaluated and based on the knowledge obtained   from the project a proposition on how to improve the production process has   been made.

    Effect of impact velocity on the fracture of wood as related to the mechanical pulping process2001In: Wood Science and Technology, ISSN 0043-7719, E-ISSN 1432-5225, Vol. 35, no 4, p. 343-351Article in journal (Refereed)
    Abstract [en]

    The fibre separation step in refining is crucial for energy consumption in subsequent refining where the pulp properties are developed. The size reduction of chips during refining is dependent on refining intensity and chip strength. Factors affecting these two parameters are discussed in a literature review. The impact strength of chips and the break down of chips to separate fibres are also discussed. Specifically the effect of impact velocity on the fracture of wood has been studied by use of a falling weight impact tester. Samples were prepared from a freshly cut log of Norway spruce, Picea abies, and the impact strength was measured using an instrumented falling weight impact tester. An increase in impact velocity from about 2.7 to 4.8 m/s resulted in an increase in impact strength of about 50%.

    A Micromechanical Model of the Deterioration of a Wood Fibre1999In: Journal of Pulp and Paper Science, ISSN 0826-6220, Vol. 25, no 2, p. 66-71Article in journal (Refereed)
    Abstract [en]

    A simple analytical model is presented in this paper for the prediction of the stiffness degradation and the damage state in a wood fibre, loaded in uniaxial tension or shear. The model is based on an assumed displacement field together with the minimum total potential energy theorem. For the damage development, an energy criterion is employed. The model is applied to a specific example and the relevant stiffness coefficients are calculated as a function of the damage state. The damage development as a function of the applied loads is also given. The results from a specific example considered indicate that a tensile load affects the stiffness degradation to a larger extent than does a shear load.

    Effect of Temperature on Fracture of Spruce in Compression, Investigated by Use of Acoustic Emission Monitoring2000In: Journal of Pulp and Paper Science (JPPS), ISSN 0826-6220, Vol. 26, no 8, p. 294-299Article in journal (Refereed)
    Abstract [en]

    Acoustic Emission (AE) monitoring during compression of wood has been used to investigate the fracture history with specific emphasis on its dependence on temperature, moisture content, strain and loading direction. The wood was compressed in both the lateral and longitudinal directions in order to select preferred modes of deformation to achieve desired irreversible changes in the wood structure. The elastic modulus, the compressive strength and the cumulated number of AE events decreased with increasing temperature. It was concluded that the most efficient loading direction is longitudinal in order to introduce flaws in wood under compression and that a longitudinal compression of 24%, corresponding to a specific energy input of 3 kWh/ton, is needed in order to achieve substantial changes in the wood structure. The compression should be carried out at temperatures well below 120°C in order to introduce many failure sites.

    On the energy consumption for crack development in fibre wall in disc refining - A micromechanical approach2009In: Holzforschung, ISSN 0018-3830, E-ISSN 1437-434X, Vol. 63, no 2, p. 204-210Article in journal (Refereed)
    Abstract [en]

    An analytical model has been applied to calculate the acquired strain energy density in order to achieve a certain damage state in a softwood fibre by uniaxial tension or shear load. The energy density was found to be dependent on the microfibril angle in the middle secondary wall, the loading case, the thicknesses of the fibre cell wall layers, and conditions such as moisture content and temperature. At conditions, prevailing at the entrance of the gap between the plates in a refiner and at relative high damage states, more energy is needed to create cracks at higher microfibril angles. The energy density was lower for earlywood compared to latewood fibres. For low microfibril angles, the energy density was lower for loading in shear compared to tension for both earlywood and latewood fibres. Material parameters, such as initial damage state and specific fracture energy, were determined by fitting of input parameters to experimental data.

    Co-Creative Learning - using IT to Visualise Progression (CIP): En studie av former för systematiskt kvalitetsarbete på klassrumsnivå2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the study is partly to understand how systematic quality management can be implemented at the classroom level and partly what it means to apply it from a student perspective, and to compare student progression with that of a control group. As a result of this, this study contributes with a method on how quality management can be implemented at the classroom level. This working method is named Co-Creative Learning - using IT to Visualise Progression.

    This is an action research study that encompassed questionnaires, focus groups and a time series. Three assignments from 65 students were assessed in the study, out of which two were compared to those from the control group.

    To enhance reliability and validity the selected control group were from the same catchment area, had qualified teacher with corresponding number of working years who also worked with formative assessment and visualising criteria. Two assignments were identical for both groups, and thus, the two groups' results could be compared.

    To minimise the effects of the presence of a teacher during evaluation, the students were not brought together to form focus groups, until after the grades were communicated. They then reflected on continuous improvement efforts, quality, inclusion, understanding objectives, perceived progression and the use of IT.

    Before the concluding discussion the collected data sets were analysed separately. The results showed the difference in both student experience and progression. The main differences lay in the student experience: where change primarily affected the students’ involvement; the extent to which the students were satisfied students with their own development.

    In the time series, the differences were not as high as in the student experience. The studied group started at a slightly lower grade, and completed at a slightly higher grade, than the control group. It was mainly the boys who accounted for the progression. One reason for could be that the girls

    already held high average grades (leaving little room for progression). Compared to the control group, the differences with the boys in the studied group remains.

    The conclusions drawn are thus that the method enhances progression, but that the main benefits are harvested from the enhanced educational experience of the students.

    Sterilisering av medicinska modeller: En studie av lämpliga metoder2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The use of medical models within the Swedish healthcare is limited. One reason for this is the lack of knowledge how to sterilize them to be able to use the in an operating room. The goal of this thesis has therefore been to investigate if medical models manufactured by rapid prototyping can be sterilized by any of the methods approved by the Swedish authority Socialstyrelsen. The study has covered two different rapid prototyping methods FDM - Fused Deposition Modeling and JP - Jet Print. The two machines that were used are Stratasys Prodigy Plus (FDM) and ObJet Eden 260v (JP). The building materials that were used are P400 ABS in FDM and FullCure720 in JP. The support materials that were used are P400-SR in FDM and FullCure705 in JP. In order to avoid misconceptions with various stakeholders has a definition of what a medical model is been created. Different grades of purity has been studied and how to achieve them. In order to determine the purity of the samples before and after they have been sterilized have an environmental investigation been performed. Due to different sterilization methods can affect the material in different ways and hence its shape have a deformation study been performed. A number of reference geometries have been measured before and after they have been subjected to the sterilization process.  In order not to skip any aspect and to have measurable and comparable values have an experimental plan been constructed. The conclusion to be drawn after the study is: Sterilization of FullCure720 with saturated water vapour works and the material can be considered sterile. Sterilization of P400 ABS with cold chemical sterilization also works; however, the material can only be classified as a high-purity material. The other test samples can only be classified as clean. The shape changes that have been measured are all below 0.5 mm and are therefore considered not to have any bearing on the medical model's function.

    Abstract [en]

    This project is a about studying and anylazing shrinkage during the   use of a EBM-machine in the material Ti6A14V. The study is done to anaylze   how prints of diffrent size and printing direction are affected by the   shrinkage. The project is done by two students at Mid Sweden University in   Östersund and the project is requested by the research department of the   university. Research has been made before the start of the project to give   the students a solid understanding in the matter. During the research for   information it was found that the shrink could be minimized by using   supportmaterial in the print. The design for the parts that was going to be   printed have been chosen through earlier studies of the matter where stairs   was recommended to easy be able to see what goes on in the different parts of   a print. Some details was also created so that measurements considering sharp   edges and round details could be checked for deformations if there was enough   time. Those were never measured since all the time of this project was   focused around the stairs. The stairs were printed in three different sizes.   They were also printed with and without supportmaterial and both standing up   and lying down in the printer EBM Arcam S12. When the parts had been printed   they were measured with a microscope called “Dino-Light edge Digital   Microscope”. The information gotten from these measurements were put into a   Microsoft Excel document where tables and graphs were created to make it easy   to spot the tendencies of the prints. The tendencies that were noticeable was   that the first and third step of every print had more shrink than the others.   This occurred no matter the size the stairs were but did not occur in the   parts printed with supportmaterial. No tendencies were noticed in the prints   with supportmaterial and the shrinkage that was noted in these prints might   also be because of the human factor. The trends are clearly visible in the   parts printed without supportmaterial. This might be because of the different   material in the printing plate that is stainless steel instead of Ti6Al4V.   This might cause problem for the layers that are printed closest to the   plate. The reason for shrinking in the details is also because of the fact   that the powder that is being printed gets melted and therefor shrinks. This   results in a thicker layer of powder everytime the powder is applied to the   printing surface. This is a problem that goes on throughout the whole print   no matter if supportmaterial is used or not. The work completed is considered to be well done.

    Implementering av additiv tillverkning för dämparkolv2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    On behalf of the companies, AIM Sweden and NewSoTech have the possibility to adapt a product to the additive manufacturing ben investigated. With AIM Sweden's expertise in additive manufacturing of titanium parts and NewSoTechs method for surface hardening of titanium, TiSurf ®, an opportunity for cooperation were identified. NewSoTech presented a piston to a motocross rear damper as a possible product to adapt to the manufacturing method. This formed the basis of the completed thesis. The aim of the work has been to explore the process of additive manufacturing of a damper piston and partly to generate a basis for further cooperation. This determined the objectives; to develop prototypes and test and analyze these, provide suggestions to design variations and develop a methodology for implementation of design variations. The work began with investigating the pistons function; this were done through a theoretical study and by modeling the piston with CAD software. Thereafter, the project were carried out by examining and thereby develop a process to adjust the piston to additive manufacturing. The opening process was divided into five stages, defining the problem, generating concepts, designing, manufacturing and analysis. These steps were repeated in whole or in part and could iteratively be improved. The first phase was to define the pistons design-related limitations and freedoms. In the concept generation were six different concepts developed that were considered interesting for the adaptation. These concepts were not intended to optimize the function of the piston, but only to show the potential of the manufacturing method. In the design process a methodology to easily implement design changes was developed. In the fabrication phase pistons were prepared and manufactured additively and then the necessary post-processing were performed. A full analysis of the pistons could not be carried out within the project. The result was a process of adjustment of the damper piston to the additive manufacturing method with the overlying process described above with added sub-steps identified as necessary for the process. The conclusions were that more work needs to be to perform on a complete analysis of the pistons, refine and develop the preparations for production and to evaluate and refine post processing methods.

    Abstract [en]

    The measurement of reflectance is important for the analysis and modelling of laser-material interactions. Unfortunately, most of the reflectance data presently available consider only polished pure metals rather than the commercially available (unpolished, oxidised) alloys which are actually being processed. This paper presents the results of reflectance measurements carried out on as-received engineering grade metals including: hot and cold rolled mild steel, zinc coated mild steel, stainless steel, aluminium alloys, copper and brass. The measurements were made using an integrating sphere with an Nd:YLF laser at two wavelengths (1053 nm and 527 nm). The results obtained differ considerably from existing data for polished, pure metals and should help to improve the accuracy of laser-material interaction models.

    Energiåtervinning vid LC-raffinering – Förstudie2008Report (Other academic)
    Abstract [en]

    Normally, steam recovery from a conventional low consistency (LC) mechanical pulprefining system is not possible. This is due to the fact that the temperature level in theLC-refiner is less than 100°C. The steam with such a low temperature and associatedpressure has limited value in the mill. In this project, we study a concept of increasingthe temperature in the refiner to a level were process steam with higher quality can berecovered. The temperature level can be increased by transferring heat from outgoingpulp or drainage to incoming pulp or water. This makes it possible to recover heat fromthe process.An initial estimate indicates that steam recovery from LC-refining systems may have agood economic potential. Three cases have been analyzed: Case A: Steam recovery incombination with pulp/pulp heat exchanging, Case B: Steam recovery in combinationwith a pressurized screw press and finally Case C: steam recovery in combination withpump/water heat exchanging.Case B show the best specific steam recovery, 87% kWh recovered steam per kWh usedelectricity. This concept has a lower technological uncertainty compared to cases A andC as it does not need heat exchanging from pulp.The specific heat recovery from case A and C is 78% and 82% respectively. However,the suggested heat exchangers used in these cases do not exist on the market today.There is hence a need for development of exchangers that can handle pulp with highviscosity. The technological risk associated with the screw press scenario is lower and itis likely that this concept is easier to implement.

    The aim of this study has been to contribute with knowledge regarding in what way a processorientation can improve the way public sector manage contracts. As a method a qualitative multicasestudy was used. Three municipalities, and the way they manage contracts with residential carehomes for children and young persons (HVB) was studied. The study showed a complex situation surrounding the carecontract management in public sector. As a way of handling this complex situation the municipalities would gain from using a systems thinking, with the values, tools and workmethods that characterizes Total Quality Management. With an increased processorientation using processmanagement as a tool, the municipalities could improve the quality in their process for managing contracts.

    Abstract [en]

    How on Earth did this happen? The question is not infrequent, but more to the point, it?s unnecessary. It arises because in many cases people haven?t thought things through beforehand. Yes, sometimes people can be unlucky, but far from every time that things go awry; bad luck is never so consistent - by definition. Thinking things through properly beforehand might seem a fairly obvious requirement for making a good decision, but startlingly often, even critical decisions are made without any in depth analysis. Well, there may have been some background data lying around somewhere, but not much is done with it. Though it's easy to blame authoritarian leadership or the like, poor decision making is far more usually due to not really knowing what to do with the available information, whether it's sufficient and what else needs to be known There?s nothing weird or idiotic about today?s decision makers, but there often is about the tools and methods available to them. It would be more accurate to say that many decision makers have been lead astray regarding their remit and capacity, but fortunately with structured decision processes they can be guided back on track far more easily than had they been as dim- witted as some of their decisions would indicate.Businesses introduce various BI solutions both timely and untimely, but what most of them don't have is any kind of methodology by which to deal with decisions. With no processes, knowledge, techniques or tools, they soon come to grief. Happily this is fairly easy to remedy.Decision processes and decision methods can be greatly improved. In this book we simply explain how to go about it.

    Abstract [en]

    The purpose of this master's degree thesis was to develop an understanding of how hospital management, in the case studied, worked to achieve changes in an organization influenced by differing professional cultures. To gain insight into the conditions that may have contributed to nurses and physicians developing appropriate attitudes and behaviours, which may have affected the organization's ability to achieve the Swedish Quality Award 2012.

     A qualitative single case study was conducted at Karlskoga Hospital, with focus groups as well as individual depth interviews.

     

    The results of the case study showed the following conditions provided nurses and physicians the potential to develop appropriate attitudes and behaviours, which may have influenced the hospitals ability to achieve the Swedish Quality Award:  

    • Responsibility and influence over the development processes.
    • Participation in management teams and quality development groups as well as individual fields of responsibility.
    • Training programs that have given insights and skills in quality management related to clinical practice.
    • Nurses and physicians as key individuals gave legitimacy to development process, and served as management advisors.
    • Collaboration between all kind of employees and responsibilities.
    • Committed management.

    Cultural Change of Applying User Involvement for Improving Healthcare Quality: A Review of the Impact on Attitudes, Values and Assumptions among Healthcare Professionals and Users2017In: Quality Innovation Prosperity, ISSN 1335-1745, E-ISSN 1338-984X, Vol. 21, no 3, p. 158-172Article in journal (Refereed)
    Abstract [en]

    Purpose: The purpose of this study is to provide a review of the impact on culture (attitudes, values and assumptions) among both healthcare professionals, as well as users, when involving users for improving quality in healthcare.

    Methodology/Approach: The paper is based on an extensive, narrative literature review considering studies that included professional’s and users experiences of user involvement in quality improvement. The included articles were analyzed using an interpretive, along with a deductive, approach according to a theoretical framework.

    Findings: The results indicate that there is currently limited research focusing on the impact of user involvement in quality improvement processes regarding professionals’ and users’ attitudes, values and/or assumptions. The articles identified during the study provides situations and statements, during the process of development, which can be interpreted as change in the culture. Although few articles specifically draw conclusions on user involvement as a “tool” for cultural change, the authors interpret several findings which strengthens that theory.

    Research Limitation/implication: Research published in other databases could have been missed. The authors have tried to avoid this by using a snowball method reading references in identified articles.

    Originality/Value of paper: The review provides a platform for both future research and the development of current practice within the area. There have been literature reviews showing obstacles and enablers when using patients, users and relatives in quality improvement work, but few which investigates cultural change.

    Stöttar kvalitetsteknik strategiskt arbete med informationshantering?: Mognadsmodeller och standarder som stöd för strategiskt arbete med verksamhetsinformation2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study aimed to identify what a suitable model for Information Governance should contain. In order to find out, I analyzed which models people commonly used, which challenges people expressed and to what extent Quality Management supported dealing with these challenges.

    The study mostly relied on literature studies. The presence of values, key temes and challenges have been noted and analyzed. A questionnaire was sent out to 80 IG-professionals and interwievs were held with four people with in-depth experience from working with information Governance. In order to define the scope for this study ” Quality Management has been delimited to values and key themes used in Excellence Models and the corner stones of TQM.

    The analyzes indicates that the expressed challenges to a great extent could be met with values and key themes present in Quality Management. Models dealing with Information Governance and BPM, Business Process Management, could also support dealing with the challenges, esp. dealing with stakeholders.

    Ackumulering av ånga: Effektivare ångproduktion vid Akzo Nobel Stockvik2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report aims to examine if it is possible to install an accumulator for steam-accumulation at the steam plantof Akzo Nobel Stockvik and to calculate its dimensions. The accumulator’spurpose is to level out the steam production when there is intermittent usage of steam at different steamconsumers.

    Within site Stockvik it is possible to use internal fuels such as CO-gas and hy-drogengas for steam production, the use of internal fuel is both environmental and economically positive.When large steam demands occurit is not sufficient to only use internal fuels and oil has to be used to produce steam as backup to meet the steam demand.An accumulator can be used to store steam at low steam demand and use at high demand instead of producing steam with oil as fuel.

    An energy audit shows that the two major consumers also has very varying needs of steamwhich results in a need to use oil as backup fuel in boiler 3.This shows that there is a need of an accumulator in the system.

    The accumulator can be installed close to the steam plant which reduces the energy losses. Three accumulators havebeen calculated from an average effect of boiler 3. The accumulators havea total volume of 29, 70 and 112 m3. Large quantities of data from the steam process are digitally stored atAkzo Nobel, this data have been used to compare the different accumulators to the actual steam production 2015 and 2016.

    The profit of installing a steam accumulator is independent of the accumulator size but the cost of installing the accumulator increases with larger volume.The shortest payback period 4,4 years is when choosing the smallest accumulator, 29 m3.Environmental benefitsareachieved by a reduction of oil usage by350 m3/year whichreduces the CO2emissions by 1000 tons/yearand SO2emissions by 1,3 tons/year

    Abstract [sv]

    Tillverkning av slutprodukter med additiv tillverkning   blir allt vanligare. Slutprodukter har högre krav på detaljens mekaniska   egenskaper än prototyper gör. Forskning har visat att porositeten är av stor   betydelse för en detaljs hållfasthet. Med additiv tillverkning finns goda   möjligheter för direkt processövervakning och kontrollsystem. Inom electron   beam melting finns sådana system men de saknas en validering av resultatet   från dom systemen. I de här arbetet har prover med designade defekter   tillverkats. LayerQam bilder från tillverkningen har analyserats med Defect   Detector. Data från analysen har visualiserats. Resultatet har studerats samt   att det har tagits fram en Defect Detector-analys med högre precision.   Utvalda prover har undersökts i ett tvärsnitt med optisk mikroskopi samt i 3D   med mikrotomografi. Undersökningarna har jämförts med varandra, de tyder på   att Defect Detector har brister i sin bedömning av densiteten. De designade   defekterna har en överskattad storlek samt brister i kompensation av   förvrängningen i synfältet i bilderna.

    On the Relationship between Sustainable Health and Quality Management: Leadership and organizational behaviours from Swedish organizations2009Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Sickness absence not only causes significant costs for organizations but also leads to other negative consequences for individuals and societies. Previous research has shown that working with organizational values within Quality Management affects job satisfaction and results in increased profitability and customer satisfaction. There would, in addition, seem to be great gains if managers, by working with Quality Management, can manage to establish sustainable health among co-workers.

     

    The purpose of the research described in this thesis was to examine how Quality Management could be practised in order to support sustainable health among co-workers and what it is within Quality Management that influences sustainable co-worker health. Accordingly, the purpose was also to contribute to the understanding of the relation between sustainable health and Quality Management. To fulfil this purpose, three research questions were asked. The results are described in three parts related to the three research questions and are the product of six case studies carried out in seven different organizations.

     

    Interviews with managers and workshops with co-workers were carried out to investigate how Quality Management can be practised within organizations in order to promote sustainable co-worker health. These investigations took place in four organizations that had received awards. Three had been awarded for their excellence in leadership, work environment and co-workership, along with improved profitability; one for its successful implementation of quality programmes. The results are descriptions of methodologies, behaviours, values and organization structure used by the organizations to support sustainable health. These are exemplified with practical examples. The methodologies, behaviours, values, and organizational structure are considered possible for other organizations to adopt and all of them are already supported in the quality, management and leadership literature. Support from the health literature is also found for most of the behaviours, methodologies, values, and organizational structure.

     

    Surveys and focus groups interviews were carried out in five different organizations in order to find out what is of most importance when practising Quality Management in order to influence sustainable co-worker health. The results pointed to ‘Leadership Commitment’ as the most central of the values for achieving sustainable health among the co-workers. Furthermore, the values ‘Continuous Improvements’, ‘Participation of Everybody’ and ‘Customer Orientation’ were found to be related to sustainable health among the co-workers. The values ‘Leadership Commitment’ and the value ‘Participation of Everybody’ were then further elaborated to find aspects of importance for sustainable co-worker health. From the value ‘Leadership Commitment’ four aspects were extracted. These were labelled ‘Empathy’, ‘Presence and Communication’, ‘Integrity’, and ‘Continuity’. The results showed relations between the value ‘Leadership Commitment’ within Quality Management and sustainable health among the co-workers. Thus it is essential for leaders to work in accordance with that value to achieve results in the work towards sustainable co-worker health. The results indicate that this requires management and leadership that are characterized by the aspects above. The leaders have to:

     

    • Really understand the co-workers and their work situation.

    • Be present and available for co-workers and communicate with them.

    • Act as a role model, be fair and keep their promises.

    • Stay in their positions long enough to build up trust and confidence.

     

    The value ‘Participation of Everybody’ has also been shown to be related to sustainable health among the co-workers. This indicates that it is important to work in accordance with that value in the struggle to achieve sustainable health among the co-workers. The results imply that this value is characterized by the aspects ‘Development’, ‘Influence’ and ‘Being informed’. This could be done by:

     

    • Giving the co-workers opportunities to develop their skills and develop personally.

    • Letting the co-workers influence their work situation and taking suggestions and proposals from them seriously.

    • Having good communication within the whole organization.

     

    To manage this; the managers have to delegate more and empower the co-workers.

     

    These results were then further elaborated within another organization in order to develop a measurement approach that can clarify the extent to which the values, ‘Leadership Commitment’ and ‘Participation of Everybody’ permeate an organization. The developed measurement approach can be used to clarify the extent to which the organization is practising the health-promoting values within Quality Management and in what areas improvement is needed to increase co-worker health. The approach can also help the organization to detect those shortcomings within the management which are important for co-worker well-being. The developed measurement approach can be used to establish and enhance co-worker health by improving their well-being, satisfaction and motivation.

    Quality Management for Sustainable Health: Methodologies, Values and Practices taken from Swedish Organizations2006Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    In many Western countries today, not least in Sweden, there are a lot of organizations that have great problems with sickness absence. The costs connected to the high rates of sickness absence have also risen to alarming levels. Healthy co-workers and healthy organizations are obvious goals for many leaders, but this is not always so easy to establish. Work practices and leadership that are beneficial to co-worker health are thus vital to identify.

     

    Studies have shown relationships between company-wide implementation of quality programs and improved co-worker satisfaction along with low co-worker turn over; in other words, co-worker health along with improved customer satisfaction and financial results. Despite the great problems concerning sickness absence, there are organizations that have been awarded prizes for excellence in leadership, internal partnership, working environment, and profitability.

     

    The overall purposes of the research described in this thesis are to examine and describe how management and leadership can establish sustainable health among the co-workers and examine how the leadership for sustainable health is related to Quality Management. The in-depth purpose is to examine which aspects within the values derived from the quality movement are those that primarily influence the co-workers’ perceived health.

     

    The results presented can be described in three parts and are results from four case studies carried out in five different organizations. Three of the organizations have received awards for establishing good working environment, good financial results, and low sick leaves among their co-workers; the fourth received an award for the successful implementation of quality programs.

     

    The first part consists of results from case studies in three different organizations and describes how organizations can work to achieve sustainable health among their co-workers, with practical examples. The results are methodologies, values and organizational structure, which it is  considered possible for other organizations to adopt in their efforts to achieve good working conditions resulting in fewer sick leaves.

     

    The second part is an attempt to investigate if leadership for sustainable health is related to Quality Management. Methodologies, leadership values, organizational structure, and general values found in organizations which have achieved sustainable health are analyzed in the light of Deming’s 14 points, and a correlation is indicated. There is also correlation found between the TQM values and the co-workers’ perception of their health.

     

    The third part examines which of the aspects within the values grown from the quality movement are those that influence the co-workers perceived health. The results show significant correlation between the values and the co-workers’ perception of their health. Aspects found within the value “Top management commitment” were named; Empathy, Presence and Communication, Integrity, and Continuity. Within the value “Let everybody be committed” the aspects; Development, Influence and Being informed were found. These aspects are described in more detail and also in one model per value.

     

    The result implies that the TQM values; “Top management commitment”, “Improve continuously” “Let everybody be Committed” and “Focus on customers” are important for achieving healthy organizations and sustainable health among co-workers.
