    Børje Mogensen soffa: Uträkning av dunplymåer och dess planering2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen handlar om renovering på en soffa modell "2209 sofa" designad av Børje Mogensen. Där fokus ligger på hur dunplymåer växer fram från planering till färdig produkt. Soffans övriga renovering är med ytligt i dokumentet, för att kunna ge en överblick. Denna undersökning behövs då den befintliga litteraturens beskrivningar om dunplymåer är ganska ytliga. Det som saknas i de befintliga beskrivningarna om dunplymåer är hur du kan blanda ihop dun och bollfibrer för att få en mer lättskött plymå. Hur mycket dun respektive bollfibrer det går att ha i plymån för att den ska bli bra stoppningsmässigt. De har inte heller med någonting om hur du ska få en plymå ligga bra emot kanter på stommen. Alltså hur man ska tänka/göra med avskärningar och tillägg. Resultaten visar att bollfibern fyller sin funktion ihop med dunet och förenklar underhållet med dunplymån. Eftersom att dunplymån blev bra i stoppning så är en kubikuträkning gjord på hur mycket dun/bollfiber du behöver per kubikdecimeter (dm3). Bågtilläggen/avskärningarna blev lagom på dunplymån, de fyller ut sina funktioner och täcker alla eventuella hål som lätt kan bli om du undviker dem. Den här uppsatsen handlar alltså om att ge svar på de frågor runt dunplymåer där information sedan innan saknas och förenkla planeringen av dunplymåer i framtiden

    Abstract [en]

    The purpose of this study is to provide recommendations to further develop and improvements of models which can be applied to IT governance models for system maintenance. The work investigates gaps in the implementation and using phase of the model pm3 and also models which are inspired in pm3. The aim of the present paper is to answer the research questions which are related to (1) which critical success factors that have an impact on the governance of system maintenance management and also for the model pm3 and (2) how maintenance management models can further be developed and improved. This qualitative study is a case study in which a questionnaire and interview in two steps have been completed. The sample of respondents have been made with a specific purpose that reflects the selected qualities and relevance of the study and also with a geographical distribution. The study resulted in a number of critical success factors for the model pm3 where some of these can be considered as general for all maintenance management models. The results shows the need of a maintenance management model that is designed for the agile working method and suitable for all types and sizes of organisations. It is an area where maintenance management models and pm3  need to develop within.

    Struvit i Skövde biogasanläggning: En studie av struvitpåväxt i rör och alternativa lösningar för att minska problemet och dess uppkomst2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The goal with the study has been to find methods for cleaning and prevention of struvite at Skövde biogasanläggning (biogas plant). This to increase the efficiency and resource optimize the biogas plant and in that way get closer to a sustainable development of the society. Struvite (magnesiumammoniumphosphate hexahydrate) is a white, harsh mineral that commonly occurs in pipes, heat exchangers, pumps, and centrifuges at wastewater plants and after digestion processes at biogas plants. Struvite precipitates as a result of pH, temperatures, concentrations and supersaturation. Pipe material can also contribute. The study has been conducted through study visits and analyses of digestate and struvite at Skövde biogasanläggning to find the amount of struvite that can precipitate and where at the plant this happens. A simple benchmarking has been conducted, which shows that struvite precipitation at biogas plants mainly occurs in heat exchangers and that the fouling is temperature dependent. Materials and chemicals have been studied to find methods for cleaning and prevention of struvite. The study has shown that struvite mainly occurs in the heat exchanger and in pipe bends at the biogas plant and that it is dependent of the pH, supersaturation, temperature and high concentrations of phosphorous, magnesium and ammonium. A theory has been made from the study that the mineral first appears in the chamber between the digesters and heat storage tank. The study further shows that the most effective methods to clean fouling of struvite is to by hand chip the mineral alternatively replace the pipes. To prevent fouling of pipes a combination of methods is recommended, which minimizes the energy usage at the plant and prevent stops in the biogas production. Chemicals should be used if crystallization is to be completely stopped. The chemicals should be added in the above- mentioned chamber. Also planned maintenance should be conducted to minimize fouling. The pipes that are to be replaced should be replaced with pipes made of plastic materials. By doing this the resource efficiency increases and unnecessary environmental impact of the plant is avoided. The study has only included a rough cost analysis. To further support the above- mentioned methods a deeper economic analysis is recommended, which should include a study of chemical dosage and inspection sites for planned maintenance.

    Prognostisering: En fallstudie för att jämföra Holt-Winters metod och Regressionsanalys2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study has been to compare the accuracy of prognosis tools and how well they do with regards to seasonal variation and known deviations in order to decide which method is more suitable for companies with the goal of optimizing their staffing. The study has used Systembolaget as a case to compare two methods of prognosis. Data has been retrieved from Systembolaget and includes the company's sales. The methods that have been compared are Holt-Winters method and regression analysis. This has been done by applying the methods in order to generate a forecast and then evaluating the result through MAPE. Application of these methods was done with Excel and SPSS. The study showed that, under the present circumstances, both methods on average gave equally accurate forecasts. Holt-Winter's method however, forecasted more accurately week by week, while the regression analysis projection on average yielded almost equal percentage error. The conclusion that was generated by the study was that Holt-Winter's method is preferable for companies with this type of sale if the purpose is to generate a weekly accurate forecast. On the other hand, the conclusion may vary if methods are optimized and more data is available.

    Tillämpning av blockchain inom food supply chain management2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: As a result of food supply chain management, we have access to fresh food from all around the world. But there are some encounters that food supply chain has to deal with. The E. coli outbreak in the US is an illustrative of a widespread problem faced by the food supply chain.

     

    Purpose: The purpose of the study is to examine how blockchain technology can be used in food supply chain management and see what the interest of the customer looks like.

     

    Method: The methodology of the research to examine how blockchain can be used in food supply chain management was through literature study, and questionnaire to get a better grasp of the customers interest.

     

    Result: By using blockchain technology in food supply chain management it improves the information flow, while becoming more transparent between the actors. Blockchain technology improves the security of FSCM and traceability of a product. You can automatize several processes of FSCM by using smart contracts and sensors. From the survey it was a found that there is an interest in the customers side and about two-thirds of the customer might pay extra if the products use blockchain technology.

     

    Conclusion: Blockchain’s features makes it ideal to be integrated in the food supply chain management, as it makes it harder to counterfeit the products, and it improves the trust between the actors by ensuring transparency of the information flow. But on the other hand, blockchain is not suitable for everyone, as it’s a complicated system and it can result in high switching cost when changing systems.

    Cloudbaserte systemer – deskriptiv beslutningsmodell: Fra litteraturens, kundens og leverandørens perspektiv2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Technology that is widely discussed in the business community today is cloud computing and cloud-based systems, as a cloud-based CRM-system. Considering that large companies, such as Google, Netflix and Microsoft, use this type of technology, it is important to ask whether such systems add something to the business or whether it is just an IT trend. The purpose of this study is therefore to create a decision model that will determine whether the company will implement a cloud-based system or maintain it in on-premises. The decision model should shed light on various criteria for cloud-based solutions. The study will be designed with the help of the TOE framework (technology, organization and environment). The aim of the study is to answer the following research questions: (1) What are the consequences and benefits of cloud-based systems? (2) what are the differences between the criteria in the literature compare to what you  practice? (3) Are there differences in the views of the supplier and the customer around this area? The result is based on qualitative interviews with people from the supplier and the customer. The interviews also represent the TOE framework. In addition, an interview with an external expert has been carried out in order to evaluate and support the results of the conducted interviews. The survey has resulted in a decision model with three alternatives and eleven criterias. The analysis shows that there is a difference in what the literature emphasizes compared to what you actually are doing.  The views between the supplier and the customer are also different. Where the customer does not want to lose control and experience a lock-in effect. On the other hand, the supplier wants to deliver the latest technology and give new challenges to their employees. The study can be concluded as follows: the main reason for not implementing the cloud-based system for the customer is; deposit, cost and loss of control. The main reason for implementing the cloud-based system for the vendor is; consultant development, functionality and availability.

    3D-printing: a future “magic wand” for global manufacturing. How can we benefit from it today for sports and health care?2017In: Proceedings of the 5th International Congress on Sport Sciences Research and Technology Support, icSPORTS / [ed] Jan Cabri, Pedro Pezarat Correia, INSTICC Press, 2017Conference paper (Refereed)
    Abstract [en]

    3D-printing, or as it is also known, additive manufacturing (AM), is promising to be one of the determining manufacturing technologies of the present century. It is not a single technology but a family of rather different ones common in the way components are made, adding materials layer by layer. Additive manufacturing is already quite competitive to existing and well established technologies, but it also can provide unprecedented flexibility and complexity of shapes making components from the materials as different as cheese, chocolate and cream, live cells, concrete, polymers and metal. Many more materials we were not even thinking about few years ago are also becoming available in additive manufacturing, making it really believable that “only the sky is the limit”. During the time available for the keynote lecture, we will analyze the present position of AM in relation to other technologies, the features that make it so promising and its influence upon the part of our life we call sports and health, using the examples relevant to the Congress areas from computer systems to sports performance. Out of all enormities of materials available for different representatives of this manufacturing family we will concentrate at polymers and metals. AM technologies working with these two material families are already providing some unique solutions within the application areas relevant to the Congress' scope. We will also talk about some limitations inherent to the AM in polymers and metals to have the awareness that though the limit is somewhere “high in the sky”, it still exists.

    Långsiktig planering i projekt med agila metoder: En fallstudie på ett IT-företag2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Companies are constantly challenged to maintain but also to expand their market position. According to a study it’s problematic to carry out successful IT-projects. Dependencies, coordination and long term planning are three factors which has shown are difficult to master in bigger projects. The aim with the study is to in- vestigate how these aspects work in one case, through a case study on an IT com- pany. The goal is to contribute with research to the subject of long term planning in IT-projects where agile methods usually is used today. Previous research and theories as project management, agile project management, planning methods, scaling methods, coordination methods and change management are used as a base for the study. An exploratory qualitative study has been performed at the case company, the generated result composes of interviews with personnel from the company. The result showed how the methods and theories where used in the case company mainly focusing on long-term planning and workflows. Generally, the same thoughts where shared among the personnel, but because of the open questions the responder got encouraged to elaborate and explain their opinion leading to new information and aspects even when they agreed on the topic. When analyzing the result, I show that a clear framework, implementing of sim- ple work methods and the project management were all important to be able to conduct long-term planning and handle dependencies in projects. The conclusion was to implement the scaling method SAFe but also to use coordination methods. An important aspect is to include change management processes and theories when implementing or changing something. Further studies suggest that research in this article should be carried out on more companies and studies if the imple- mentation of the agila scaling method SAFe has a positive effect in a company.

    Anbudsstrategi vid offentlig upphandling: Beslutsmodell vid analys av anbud och prissättning hos Permobil AB2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of the study has been to investigate if it is possible to apply a decision model when solving a problem with bidding strategies in public procurement. When a company has costumers comprehended by the laws in public procurement, there are certain rules involved. For a company it is important to be aware about these rules, when setting their bids. Though this is often not enough for a winning procurement, because of the fact that the products comparison prices need to be lower than the competitors'. A decision model, based on data from earlier procurements, has been developed to reinforce a tool with bidding strategies. The decision model is composed by various theories, like decision matrix, decision tree, lognormal distribution and expected monetary value. The procedure through the study has contained data and information acquisition via interviews and other references like literature, articles, thesis and procurements. Based on a general decision matrix and a decision tree, as with calculations, the decision model has been generated. The decision model is mainly designed to reinforce a tool for companies supplying electric wheelchairs to costumers but could also be applicable in other types of procurements. The decision model could be a support when constructing a tool, which consequently could be used by decision makers. The decision makers can however not only adopt the ideas based on earlier procurements. They also need to analyse the competitors’ situations in present time.

    Bortom melodi och harmoni: det beväpnande ljudet: Om ljud som vapen och sonisk krigsföring2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete undersöker hur soniska vågor kan användas som vapen. Särskild vikt läggs vid att

    förstå hur ljudet avtäcktes från att vara en osynlig och hämningslös energi till att bli en fysiskt

    producerande våldsam kraft under den megafoniska eran och efter. Uppsatsen argumenterar för

    att soniska vapen måste föregås av avancerad teknologisk utveckling samt ett intresse för att föra

    ett annat typ av krig, utan dödsfall och skjutvapen. Flera exempel ges som visar att ljudvapen

    också ofta används för att kontrollera en population. Sonisk krigsföring fastställs till att innefatta

    användandet av psykologisk, våldsam och fysisk akustisk kraft för att alternera eller påverka

    psykiska och fysiska aspekter hos en population, kropp eller folkmassa.

    Waiting lines: A designing of a mobile self – checkout service for grocery stores2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Waiting lines is something people experience every day but many  people still hate them especially at grocery stores. For many years, the manual barcode reader has been optimal solution to deal with waiting lines at grocery stores. But, recently, Amazon and Hypercity have  shown that it could be more effective to use mobile self – checkout services to remove waiting lines. In Sweden, the idea of having a mobile self – checkout service has not yet reached out to the larger part of the market. There is, therefore, possible to benefit from introducing a mobile self – checkout service before the competitions start to move. The purpose of this study has, therefore, been to design a mobile  self – checkout service for grocery stores which fulfills the user  experiences better than available self - checkout services. The research has been conducted through a case study, this has been done to  understand the depth of the customers’ user experiences. The result has shown that people don’t like to spend too much time learning a new system and want to be competent at carrying out tasks without too much effort. The result concludes that users have high requirements for efficiency, this is because they want to perform their intended tasks without having to waste much time. The users desire to carry out their tasks with as few steps as possible. If possible, the users want tasks to be completed similar to Amazons 1 – Click technique which allows  customers to make online purchases with a single click.

    Kostnadskalkyler med osäkerhetsanalys och subjektiva sannolikheter: En fallstudie på Biogas Mellannorrland2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose with this study is to show how the subjective uncertainty analysis can be applied to the cost estimates and examine how the attitudes towards risk budgeting of construction projects works. Biogas Mellannorrland is based on a case study and focuses on four location options for the biogas plant. For each option, a cost estimate in form of a fixed cost and variable cost elements, where the latter are uncertain. Pearson-Tukey method have been applied as a method to estimating subjective probabilities. An assumption is made so that the uncertain costs are normally distributed, where the parameters’ mean and standard deviation collected from respondents indicating percentiles at 5% and 95% for doubtful cost elements. In order to identify the project managers risk attitude, the risk premium method will be used to calculate where the expected value is produced by Pearson-Tukey method. The expected value is subtracted with certainty equivalent, which consist of the budgeted amount. The study was conducted through interviews in order to obtain the costs and the subjective probabilities. The study results show that it is difficult to determine which option is the best, or the worst, by just looking at the expected value. The risk premium shows that each option is a risk averse choice for the project managers, since the risk premium was greater than zero.

    Abstract [sv]

    Vid mitt sista år på Träakademien och Mittuniversitetet i Kramfors tillverkade jag ett skåp med en sinkad låda, vilket i sin tur gjorde att jag skrev den här uppsatsen som behandlar genomgående- och halvförtäckta sinkor gjorda med handverktyg.Jag ville i mitt arbete med mitt examensjobb undersöka vilka verktyg som är adekvata för arbetets process och vilka metoder som finns för att tillverka sinkor med hjälp av handverktyg, och kom fram till att det finns två sätt att göra på, antingen börja tillverkningen av sinkor, eller att börja med tappar. Men i den litteratur jag hade att tillgå fanns inga instruktioner för hur en går tillväga i processen med att börja med sinkorna, vilket resulterade i en punktformad redogörelse i både tillverkningen av genomgående- och halvförtäckta sinkor.Mitt resultat visar att idogt arbete och upprepning verkar skapa ett slags muskelminne vilket underlättar och förbättrar resultatet under resans gång, samtidigt som det visar sig att det inte spelar någon vidare roll huruvida en börjar tillverkningen med att såga sinkorna eller tapparna, då resultatet blir detsamma beroende på upprepning.

    Insights from Sustainable Cleveland 2019: An Initiative Driving Sustainable Regional Development by Large Scale Summits, Collective Visioning, and lots of Creativity, Culture, and Appreciation2016In: Valuing and Evaluating Creativity for Sustainable Regional Development / [ed] Laven, D. & Skoglund, W., Östersund, 2016, p. 255-258Conference paper (Refereed)
    Abstract [en]

    Purpose

    Given the current growing challenges regarding sustainability, the need for massive engagement, creative solutions, and large scale change is evident. The challenges are e.g. clearly elaborated in the 17 sustainable development goals recently proposed by the United Nations. In facing these global challenges on a regional level, there is an urgent need for spreading and advancing best practice on how to involve the various citizens of a region in collectively co-designing, driving, and realizing a more sustainable region and future for all.

     

    An initiative that currently is up and running, engaging hundreds of people annually, continuously evolving, and showing promising results of such abilities is Sustainable Cleveland 2019 (“Sustainable Cleveland”, 2016). Starting in 2009, it is a 10-year initiative that engages and invites everyone in the region around Cleveland to work together to design and develop a thriving and resilient Cleveland that leverages its wealth of assets to build economic, social and environmental well-being for all. Since the start, results from the initiative show enhancements of both economic as well as social, cultural, and environmental development of Cleveland and the surrounding region. The initiative is interesting for many reasons, one being the change management approach of Appreciative Inquiry (AI), a promising research based approach from Case Western Reserve University (which is located in the region), which was applied at a large scale and in close collaboration with representatives from the cultural and creative sectors. It is an approach that actively enables, engages, and invites people in co-designing and self-organizing for realizing a more sustainable future in what might be described as an “appreciative social movement” (Boland, 2013). The approach relies on  a process that actively explores citizens’ appreciative perspectives on the best of what is, their dreams and hopes for the future, and how they see that this future can be designed and realized.  At the heart of the initiative is a thoughtfully designed AI large group summit, annually gathering hundreds of participants from all parts of society in a process of co-creation during two days. Interestingly, the application of AI has also been generally observed to provide the fastest, most consistent, and transformative results when focusing on sustainability (Cooperrider & Fry, 2012). Furthermore, the initiative is organized around annual celebration topics as a means to create a common focus within the region on one specific sustainability challenge such as “Clean water”, “Vital Neighborhoods” or “Zero Waste. The term itself, “Celebration Topics”, reflects how the initiative consistently and deliberately applies an “Appreciative Eye”, as described by Cooperrider & Srivastva (1987).  

     

    The purpose of this paper is to identify and contribute insights concerning the strengths of the Sustainable Cleveland 2019 initiative, with a special focus on how it uses the cultural and creative sectors as resources and drivers for sustainable regional development. The cultural and creative sectors refer in this paper to the performing arts and the seven creative fields especially highlighted by UNESCO – Crafts and Folk Arts, Design, Film, Gastronomy, Literature, Media Arts, and Music.

     

     

    Approach

    The paper is based on a case study conducted by the eight authors. Data has mainly been collected by participant observations and interviews with participants and organizers before, during, and after the Sustainable Cleveland summit in September 2015. The initial analysis was conducted during a follow up workshop in October 2015 and was preceded by structured individual reflections. Based on the workshop results, a secondary analysis was conducted where the strengths relating to the cultural and creative sectors were picked out and grouped into themes.  

     

     

    Findings

    As a result, several strengths were identified. During the secondary analysis, those strengths were grouped into three themes as presented below.

     

    1. Making the core process of Sustainable Cleveland 2019 more engaging and fruitful:

    One of the most obvious related strengths is the way the initiative uses practices from the cultural and creative sectors to increase the engagement in, and output of, the core processes. Many of the methods used within the initiative, such as for visioning, creating new ideas, and playfully prototype as a way to explore new ideas, have its roots in the cultural and creative sectors. One example is the practice of “rapid prototyping”, brought in from the design studio IDEO.

     

    2. Nurturing a reverence for the environment, raising awareness, and inspiring action:

    Another strength that relates to using the cultural and creative sectors as resources and drivers for sustainable regional development is the initiative’s close collaboration with local institutions of e.g. theater and music for putting focus on, engaging in, and elaborating the understanding of the annual celebration topics. On example is the short plays “Fire on the Water”, given by the Cleveland Public Theatre during the year of 2015 when the celebration topic was “Clean Water”. This activity focused on issues of sustainability in fun, intimate and personal ways. The work focused on how the environment can shape identity and celebrate the remarkable recovery of Cleveland’s waterways. Another example is the play “Air Waves”, given in 2014, weaving sustainability themes into a story of loss, reckoning, forgiveness and honeybees. Generally, the cultural and creative sectors are very much used as resources to nurture a reverence for the environment and raise awareness about critical issues related to sustainability. More about how the Cleveland Public Theatre, Tri-C, and Inlet Dance Theatre have been using the performing arts to raise consciousness and inspire action around water can be seen in a video produced by the initiative (“New video: How performing arts advance sustainability”, 2016).

     

    3. The cultural and creative sectors themselves are the focus of sustainability action:

    Finally, the cultural and creative sectors themselves are also the focus for sustainable development and action. Obviously, challenges such as decreasing waste, avoiding toxic substances, and lowering energy consumption are relevant also within these sectors themselves. Gastronomy, in terms of “Local Food”, was furthermore chosen as the overall celebration topic of the initiative in 2012 which made this an area for considerable sustainable development actions. As a result, several accomplishments were, and are continuously, achieved related to gastronomy within the initiative (“Local Foods”, 2016).

    Commercial experiences from a customer perspective: Elaborated, defined and distinguished2007In: Proceedings of the 10th International Conference on Quality Management for Organisational and Regional Development, Lund 18-20/6 2007, Lund: Linköping University Electronic Press, 2007, , p. -Conference paper (Other academic)
    Abstract [en]

    A new type of business offering is currently gaining much attention, a type which in some aspects appears to be distinct from goods and services. These offerings are usually denoted as commercial experiences and are claimed to provide higher customer value than other types of offerings as they, for example, engage customers in an inherently memorable way. The understanding of what constitutes commercial experiences is however still scant. The purpose of this paper is accordingly to take a closer look at the commercial experience concept from a customer perspective. The paper aims specifically at elaborating and defining commercial experiences as well as distinguishing them from goods and services. Approach The paper is based on literature studies. Findings The authors identify memorable as the fundamental distinctive characteristic for commercial experiences. Memorable events are then shown to be strongly emotional events. Finally the two-factor structure of affect is used to show that the factor �strong engagement� is a critical driver of commercial experiences. As a result of the elaboration the authors also propose a new definition of commercial experiences and distinguish commercial experiences from goods and services in three ways. Originality/Value The paper increases the currently scant understanding of commercial experiences.

    Is Innovation the Future of Quality Management?: Searching for signs of quality and innovation management merging2017In: International Journal of Quality and Service Sciences, ISSN 1756-669X, E-ISSN 1756-6703, Vol. 9, no 3-4, p. 232-240Article in journal (Refereed)
    Abstract [en]

    Purpose: Upcoming as well as mature industries are facing pressure as regards successfully managing operational excellence, and, at the same time, driving and managing innovation. Quality management concepts and practices’ ability to tackle this challenge have been questioned. It has even been suggested that there is a need to provide and promote an updated/changed, and even re-branded, version of Total Quality Management, merging quality management (QM) and innovation management (IM). Can such a shift then actually be spotted? The purpose of this paper is to explore and see if there are any signs suggesting that QM and IM actually are about to merge. Design/methodology/approach: The study is based on literature reviews, document studies and interviews. Findings: The paper highlights three signs indicating that QM and IM indeed are approaching each other, and that it is a movement driven from both sectors, e.g., in the work with new ISO-standards and the Toyota Kata framework. Originality/value: The indicated development has fundamental and extensive practical implications. It will for example have to be followed by a similar merging of the two fields in the educational system, and in the competences of future managers.

    Design Questions for Life: Connecting Engineering Design, Appreciative Inquiry, and Other Question-based Models2015In: Proceedings of the International Conference on Engineering Design, ICED, The Design Society, 2015, Vol. 11, p. 163-172Conference paper (Refereed)
    Abstract [en]

    The Design for Life philosophy is an invitation to create new products, services, processes, and experiences that enhance human life. Research further suggests that a good life is qualitatively different than simply not having a bad life, and implies that the inquiry process during design is important.However, current engineering design approaches are not particularly clear as to which specific design questions should be used in the design process, and even less as to the role various design questions might play. Some of the current approaches even seem to use questions that inhibit Design for Life due to their strong emphasis on only solving deficiencies.This paper aims to highlight the unexplored potential of a more deliberate choice of design questions in the engineering design process. By mapping out four question-based design models and analyzing their differences in relation to the traditional engineering design process, an overview of design question types and their various sequences is produced. The analysis further highlights practical implications and potential gains when it coMES to choosing design questions more deliberately in the engineering design process.

    Why is it Suddenly so Easy to Change?2015In: International Journal of Quality and Service Sciences, ISSN 1756-669X, E-ISSN 1756-6703, Vol. 7, no 2/3, p. 334-348Article in journal (Refereed)
    Abstract [en]

    Purpose

    The purpose of this paper is to contribute with knowledge concerning how to drive, generate and energize change and development in social systems. A potential key to meet this challenge is the strength-based change management approach called appreciative inquiry (AI). A centralcomponent of AI is the “AI interview”, which has evolved into a distinct activity that enables the past and the future to be used as a generative source for on-going learning about strengths, opportunities,aspirations and results. The AI interview has in previous studies shown an often surprisingly high ability to generate development and change in social systems. However, the understanding of the generative “mystery” of the AI interview, focusing on the value experienced by both the people conducting the interview and those being interviewed, is still in need of further exploration. Furthermore, the evident generativity of the AI interview has not yet been integrated to any large extent into quality management. The purpose of this paper is to change that.

    Design/methodology/approach

    The researchers have studied the customer experience of conducting an AI interview based on feedback from 97 AI students at Mid Sweden University.

    Findings

    Among the results, eight categories of value are identified.

    Originality/value

    The paper contributes with new knowledge concerning the values experienced during participation in an AI interview. The paper also highlights ideas on how the generativity of the AI interview could be increasingly integrated into quality management.

    Industri och digitalisering i Västernorrland: En kartläggning2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the study was to map the small and medium sized industrial companies in Västernorrland and their work with digitalization. This was performed with the help of an analysis where data from the companies book keeping were retrieved from a database together with a survey that was sent to the companies. The analysis showed how the industry in Västernorrland looks like considering the development of number of companies, number of employees, revenue and more. The questions of the survey were chosen to fit with indicators from the governmental strategy for the industrial transformation. The results of the survey showed that the most of the respondents work with digitalization to some extent. Production and marketing are the main areas where the companies see the biggest possibilities with digitalization. There are very few women in the industrial companies in Västernorrland, both in general and in leading positions. This is contrary to the fact that women in general have a higher education than men, something that is becoming increasingly important with the expansion of digitalization. Support initiatives in the form of a better cooperation between schools and the industry could solve the supply of competence to the companies. The analysis shows that, except for how the industry presently looks, that it is difficult to draw any conclusions about how the companies work with digitalization. There are tendencies that high-tech companies more often themselves write about their work with digitalization on their websites which can be connected to that these companies work more actively with digitalization compared to low-tech companies.

    Renovering av en 40-talsfåtölj2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Fåtöljen var klädd i plyschtyg med medaljongmönster. Ville hitta en bra lösning på hur jag kunde få fåtöljen att se nättare ut med hjälp av formförändringar och tygval.

    Jag ville ändå ha kvar 40talskänslan i slutresultatet och började därför leta efter relevanta tyger via internet, litteratur och intervjuer med kunniga människor.

    Det var väldigt svårt att hitta tyger just ifrån 40talet därför riktade jag in mig mot textilkonstnärer och deras tyger som fanns under 1940talet. Jag kom fram till att fåtöljen var omklädd, det föregående tyget var ett enfärgat mörkblått plyschtyg. På grund av detta valde jag att klä rygg, sits och ytterarmar i ett enfärgat blått plyschtyg. Jag ville få en känsla av modernitet och elegans, därför valde jag ett spräckligt guldfärgat plyschtyg till keder och armstöd. Tillverkade keder och rimpa för att få ett nättare utseende. Lade keder längs hela ryggen och i alla rygg- och armstödsmöten.

     

    Celocrine, tagel och gråvadd blev det material som byggde ryggpiporna bäst då ryggen var trasig. Jag använde mig av traditionell stoppningsteknik då jag ansåg att det var lättare att prima materialet och bygga fram en finare form på både rygg och sits.

    Arbetet är uppdelat i olika kapitel och den genomförande och undersökande delen är störst.

    Modelling and simulation of paper structure development2008Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

     

     

     

     

     

    A numerical tool has been developed for particle-level simulations of fibre suspension flows, particularly forming of the fibre network structure of paper sheets in the paper machine. The model considers inert fibres of various equilibrium shapes, and finite stiffness, interacting with each other through normal, frictional, and lubrication forces, and with the surrounding fluid medium through hydrodynamic forces. Fibre–fluid interactions in the non-creeping flow regime are taken into account, and the two-way coupling between the solids and the fluid phases is included by enforcing momentum conservation between phases. The incompressible three-dimensional Navier–Stokes equations are employed tomodel themotion of the fluid medium.

    The validity of the model has been tested by comparing simulation results with experimental data from the literature. It was demonstrated that the model predicts well the motion of isolated fibres in shear flow over a wide range of fibre flexibilities. It was also shown that the model predicts details of the orientation distribution of

     

    multiple, straight, rigid fibres in a sheared suspension. Furthermore, model predictions of the shear viscosity and first normal stress difference were in fair agreement with experimental data found in the literature. Since the model is based solely on first principles physics, quantitative predictions could be made without any parameter fitting.

     

    Based on these validations, a series of simulations have been performed to investigate the basic mechanisms responsible for the development of the stress tensor components for monodispersed, non-Brownian fibres suspended in a Newtonian fluid in shear flow. The effects of fibre aspect ratio, concentration, and inter-particle friction, as well as the tendency of fibre agglomeration, were examined in the nonconcentrated regimes. For the case of well dispersed suspensions, semi-empirical relationships were found between the aforementioned fibre suspension properties, and the steady state apparent shear viscosity, and the first/second normal stress differences.

     

    Finally, simulations have been conducted for the development of paper structures in the forming section of the paper machine. The conditions used for the simulations were retrieved from pilot-scale forming trial data in the literature, and from real pulp fibre analyses. Dewatering was simulated by moving two forming fabrics toward each other through a fibre suspension. Effects of the jet-to-wire speed difference on the fibre orientation anisotropy, the mass density distribution, and three-dimensionality of the fibre network, were investigated. Simulation results showed that the model captures well the essential features of the forming effects on these paper structure parameters, and also posed newquestions on the conventional wisdom of the forming mechanics.

    Simulations of the Dynamics of Fibre Suspension Flows2007Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    A new model for simulating non-Brownian flexible fibres suspended in a Newtonian fluid has been developed. Special attention has been given to include realistic flow conditions found in the industrial papermaking process in the key features of the model; it is the intention of the author to employ the model in simulations of the forming section of the paper machine in future studies.

    The model considers inert fibres of various shapes and finite stiffness, interacting with each other through normal, frictional and lubrication forces, and with the surrounding fluid medium through hydrodynamic forces. Fibre-fluid interactions in the non-creeping flow regime are taken into account, and the two-way coupling between the solids and the fluid phase is included by enforcing momentum conservation between phases. The incompressible three-dimensional Navier-Stokes equations are employed to model the motion of the fluid medium.

    The validity of the model has been tested by comparing simulation results with experimental data from the literature. It was demonstrated that the model predicts the motion of isolated fibres in shear flow over a wide range of fibre flexibilities. It was also shown that the model predicts details of the orientation distribution of multiple straight, rigid fibres in a sheared suspension. Model predictions of the viscosity and first normal stress difference were in good agreement with experimental data found in the literature. Since the model is based solely on first-principles physics, quantitative predictions could be made without any parameter fitting.

    A model for flexible fibres in viscous and inert fluid2007In: 61st Appita annual conference and exhibition, Gold Coast, Australia, 6-9 May 2007, 2007 International paper physics conference, 6pp [Carlton, Australia: Appita, 2007, 2007, p. 23-28Conference paper (Other scientific)
    Abstract [en]

    A model is proposed for simulating the motion of flexible fibres in fluid flow. Care has been taken to include typical papermaking conditions into the validity range of the model. Fibres are modelled as chains of fibre segments, whose motion is governed by Newton's second law. The fluid motion is calculated from the three-dimensional incompressible Navier-Stokes equations. By enforcing momentum conservation, the two-way coupling between the solids and fluid phase is taken into account. Fibre-fibre interactions as well as self-interactions include normal, frictional and lubrication forces. Furthermore, the model considers nonlaminar fibre-fluid interactions and particle inertia. Simulation results were compared with experimental data found in the literature. The model predicts very well the orbit period of rigid fibre motion in shear flow. Quantitative predictions were made for the amount of bending of flexible fibres in shear flow. It was also possible to reproduce the different regimes of motion of flexible fibres in shear flow, ranging from rigid motion to coiled motion and self-entanglement.

    Particle-level simulations are performed to study the rheology of monodispersed non-Brownian fibers suspended in a Newtonian fluid in shear flow. The effects of fiber aspect ratio, concentration, and interparticle friction on the stress tensor of the suspension in the steady state and on the tendency of fiber agglomeration are investigated. Semiempirical expressions for the steady state apparent shear viscosity and the steady state first and second normal stress difference were obtained for the case of well dispersed suspensions in the nonconcentrated regimes. The simulation predictions of the specific viscosity were in fair agreement with previous experimental investigations.

    Simulation of semidilute suspensions of non-Brownian fibres in shear flow2008In: Journal of Chemical Physics, ISSN 0021-9606, E-ISSN 1089-7690, Vol. 128, no 2, p. 024901-Article in journal (Refereed)
    Abstract [en]

    Particle-level simulations are performed to study semidilute suspensions of monodispersed non-Brownian fibers in shear flow, with a Newtonian fluid medium. The incompressible three-dimensional Navier-Stokes equations are used to describe the motion of the medium, while fibers are modeled as chains of fiber segments, interacting with the fluid through viscous drag forces. The two-way coupling between the solids and the fluid phase is taken into account by enforcing momentum conservation. The model includes long-range and short-range hydrodynamic fiber-fiber interactions, as well as mechanical interactions. The simulations rendered the time-dependent fiber orientation distribution, whose time average was found to agree with experimental data in the literature. The viscosity and first normal stress difference was calculated from the orientation distribution using the slender body theory of Batchelor [J. Fluid Mech. 46, 813--829 (1971)], with corrections for the finite fiber aspect ratios. The viscosity was also obtained from direct computation of the shear stresses of the suspension for comparison. These two types of predictions compared well in the semidilute regime. At higher concentrations, however, a discrepancy was seen, most likely due to mechanical interactions, which are only accounted for in the direct computation method. The simulated viscosity determined directly from shear stresses was in good agreement with experimental data found in the literature. The first normal stress difference was found to be proportional to the square of the volume concentration of fibers in the semidilute regime. As concentrations approached the concentrated regime, the first normal stress difference became proportional to volume concentration.

    Abstract [en]

    A model for flexible fibers in viscous fluid flow is proposed, and its predictions compared with experiments found in the literature. The incompressible three-dimensional Navier-Stokes equations are employed to describe the fluid motion, while fibers are modeled as chains of fiber segments, interacting with the fluid through viscous and dynamic drag forces. Fiber segments, from the same or from different fibers, interact with each other through normal, frictional and lubrication forces. Momentum conservation is enforced on the system to capture the two-way coupling between phases. Quantitative predictions could be made, and showed good agreement with experimental data, for the period time of Jeffery orbits in shear flow, as well as for the amount of bending of flexible fibers in shear flow. Simulations, using the proposed model, also successfully reproduced the different regimes of motion for threadlike particles, ranging from rigid fiber motion to complicated orbiting behavior, including coiling and self-entanglement.

    Evolution of the paper structure along the length of a twin-wire former2009In: ADVANCES IN PULP AND PAPER RESEARCH, OXFORD 2009, VOLS 1-3 / [ed] IAnson, SJ, Bury, UK: Pulp Paper Fund. Res. Soc. , 2009, p. 207-245Conference paper (Refereed)
    Abstract [en]

    A particle-level numerical model is used to simulate forming with a twin-wire former configuration. The development of the paper structure along the length of the former is observed to explain the effects ofthe dewatering elements on the paper structure at different jet-to-wire speed ratios, consistencies, and target basis weights. The simulations indicate that most of the structure development takes place in the initial part of forming (forming roll) and, in some instances, at the drop to atmospheric pressure after the forming roll. Dramatic effects onthe through-thickness fibre orientation anisotropy are observed when the consistency is varied by changing the jet thickness, while changes in basis weight had less impact. The through-thickness concentration gradient was almost uniform throughout the forming process, except in the lower range of typical papermaking consistencies. This indicates that the dewatering mechanism is normally thickening, rather than filtration.

    Microscale droplet absorption into paper for inkjet printing2011In: Nordic Pulp & Paper Research Journal, ISSN 0283-2631, E-ISSN 2000-0669, Vol. 26, no 1, p. 142-150Article in journal (Refereed)
    Abstract [en]

    Digital printing using high-speed inkjet technology puts heavy demands on paper's ability to rapidly absorb the liquid. This is important for both the runability during the printing process and for the print quality. In this article, the dynamics of inkjet droplet absorption and penetration is discussed. The LucasWashburn equation has been applied to experimental results from inkjet printing on paper. The ink absorption on different paper grades is discussed in terms of the physical properties of the surface such as surface energy, surface roughness and porosity. The results of this study indicate that ASA used as internal sizing reduces the absorption speed of water based dye inkjet ink and that evaporation affects the result. The Lucas-Washburn equation can be used to some extent for describing micro-scale droplet absorption into paper, depending on the properties of the paper.

    Effektiv Timmersortering: En studie om arbetssätts inverkan på ett sågverks lönsamhet2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Globaliseringen ökar konkurrensen och kvalitetskraven vilket innebär att sågverk i dag prioriterar effektviseringsarbete högre än någonsin. Eftersom råvarukostnaden är 70 procent av ett sågverks totala kostnader är hur väl ett sågverk utnyttjar råvaran avgörande för ett sågverkets lönsamhet. För att förbättra sågutbytet strävar sågverk mot att förbättra sin timmerosorteringens träffbild, vilket medför att sorterings-parametrar ofta korrigeras. Till följd av ständiga förändringar i timmersorteringen är arbetssättet för detta sannolikt viktigt. Studien har utförts vid Bollsta sågverk i syfte att undersöka sågverkets möjlighet att arbeta mer effektivt med sin timmersortering genom att utveckla nuvarande arbetssätt och förutsättningar. Studien har genomförts i två steg, en kvalitativ del för utveckling av arbetssätt och en experimentell utvecklingsdel för utveckling av processtöd. Studien har visat en god potential för Bollsta sågverk att utveckla sitt arbetssätt vid nyskapande av timmerklasser samt dess kontrollmöjligheter. Processutvecklingen har visat sig fordra utveckling av ett beslutsstödssystem med förbättrad möjlighet till simulering och visualisering av sortering. Simuleringsfunktionen har visats vara 25 gånger mer effektivt än nuvarande simuleringsprogram. Beslutsstödssystemet har utvecklats och en utvärdering mot principer för användbara gränssnitt har visat att beslutstödet är användbart. Det utvecklade arbetssättet och beslutstödet har medfört ett antal kostnadsbesparingar i form av förkortad ledtid, förbättrad konkurrenskraft och förbättrad kontroll. Kostnadsbesparingens storlek har visats vara svår att approximera men utvecklingen har sannolikt miljonpotential. I dag finns endast presenterad forskning inom sorteringsparametrar och tekniskt utnyttjande. Potentialen i ett utvecklat arbetssätt och ett nytt beslutstöd indikerar dock bristen av forskning inom andra områden i timmersortering.

    Arkitektonisk utformning av en lagringsplattform för Business Intelligence: En litteratur- och fallstudie riktad mot små och medelstora företag2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    BI, business intelligence, which means to collect and analyse data to inform business decisions, is a concept that has grown to be a significant part of business development. In most cases, a storage platform is necessary to provide data from the companies’ different data sources to the BI-tools. There are different ways of doing this. Some of them are by the help of a data lake, a data warehouse or a combination of both. By taking this into consideration the purpose of this study is to create an architectural design of a storage platform for small and medium-sized enterprises (SME). To be able to formulate a result which holds as high validity and reliability as possible, this study conducts both a literature and a case study. The case study has taken place at an IT service company which classifies as a SME and the working methodology has been an agile approach with scrum as reference. This method was chosen to be able to efficiently follow the customer demands.  The architecture provided consists of a combination of a data hub, which acts as a data lake, and a data warehouse. The data hub differs from a data lake by harmonizing and indexing data, which makes it easier to handle. Regarding the intension of the data warehouse, it is to yield relevant and processed data to BI-tools. The architecture design of the platform that has been developed in this study cannot be said to be applicable by all companies. Instead, it can be a basis for companies that are thinking about creating a data platform.

    Kvalitetssäkring och test av leveranser vid arbete enligt scrum: En fallstudie på företaget SSG2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Failed projects are often caused by not detected failures and therefore tests should be performed at some time during the project to avoid those failures. In the agile method Scrum the tests of IT services are executed by the supplier to secure the quality of the services. In theory, no tests are performed by the product owner. This requires big amount of trust to the supplier and a close partnership. In agile methods the time and costs are fixed, and because of this there is also a risk that unfinished products are delivered on deadline. Little research about tests and Scrum can be found, and therefore the aim with this study is to evaluate how and when quality assurance and tests should be treated in the best way by the product owner in Scrum. The study aims to answer the question of which manual test type is relevant to perform by the product owner to ensure the quality of the IT services. The question about how and when the test should be executed should also be answered. The study is based on a case study at the company Standard Solutions Group (SSG) which is a technical consultancy. The methodology in the study involves interviews, observations, a survey, and a literature study. The different methods are used to gather information from different perspectives and should increase reliability. Acceptance tests are selected to be best suitable to be performed by the product owner. To answer the question about how the test should be executed the authors select to develop a checklist. The acceptance tests should be done continuously to create more efficiency, and it also should be easier to correct the errors.

    Utmaningar och möjligheter i upphandlingsprocessen - för att kunna digitalisera på ett innovativt sätt i offentlig verksamhet2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Approximately, digital transformation in public sector is procured for an amount of 59 billion Swedish crowns, according to Konkurrensverket. But despite this, the procurement process is not that effective, which may question the benefits of the investment being made. The Swedish Government has a goal to be the best in the world to utilize the opportunities that digitalization gives to the public sector, but according to Ekonomistyrningsverket, this goal is not considered to be fulfilled since there are some shortcomings in the area. Some argue that public procurement of innovation can contribute to a solution that is better suited to public needs, which is one of the reasons that the agency of innovation Vinnova was commissioned by the government to promote public procurement of innovation in the public sector. The procurement process is governed by laws and therefore the communication between customer and supplier is limited as no supplier are allowed to have competitive advantages in the procurement. This means that the requirement specification is important for public sector to fill their needs, but it claims that the process of requirements can be very complicated. The purpose of the study is to deepen the knowledge of procurement as an aspect to digitalize in an innovative way. This will be done by identifying the challenges and opportunities that exists in the procurement process. The study is conducted through an qualitative method and a literature study and interviews are used to collect data. Initially, the area is explored in a broader perspective with an exploratory approach and the collected material are further specified into a more specific area where a more focused approach is used. The results of the study indicate that there are both challenges and opportunities in the procurement process. The challenges that were identified concern the areas; specification of requirements, limits with the Public Procurement Act (PPA), the concept & meaning of public procurement of innovation and the competence of the Swedish innovation agency. Furthermore, the possibilities that were identified concern the areas; the competence of the Swedish innovation agency, specification of requirements, PPA & new way of working with the procurement process and the trend of being innovative.

    Lean Product Development för små och medelstora företag: En projektmodell för produktutveckling2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Today it is hard for companies to keep a strong market position and one part of the challenge is to regularly present new products on the market and constantly create new innovations.  The companies can accept that challenge by using Lean Product Development in the product development process. It can however be more difficult for small and medium sized enterprises as they may have limited resources. The purpose with this study was therefore to develop a project model for product development in small and medium sized enterprises. The study was built on qualitative research methodologies, first secondary data was collected through both the Mid Sweden University’s library catalog and searches in research databases on the Internet. Then, the primary data was collected through interviews to create a case study and a theoretical applicability test. The generated result showed that it characterizes the product development in small and medium sized enterprises primarily was that the manager or owner often affect the product development and the key factors for a successful product development was processes, resources, strategies and a good communication. The final project model are in general based on the general project model and did not underwent any major changes after the theoretical applicability test had been carried out. The project model consists of five phases: feasibility study, planning, implementation, closing and effect transfer. All of the presented project models could work to create processes, resources, strategies and a good communication. The mention project models differ slightly in the design and they are focusing on different areas. The differences in the models are the roles and responsibilities descriptions, decision points and the models different phases. The newsworthy this study has contribute with is how small and medium sized enterprises can work on projects in product, and one question that has been raised is how this project model could look like to promote the whole organization not only the product development departure.

    Problems Affecting Successful Implementation of Blended Learning in Higher Education: the Teacher Perspective2017In: International Journal of Information and Communication Technologies in Education, ISSN 1805-3726, Vol. 6, no 1, p. 4-13Article in journal (Refereed)
    Abstract [en]

    An increased use of blended learning environments in higher education has been an emerging trend in the 21st century. Sometimes the definition of blended learning has been so broad that it makes it hard to find any learning environment in higher education that would not be included. Many research studies have been reporting the pros and cons of blended learning from the university perspective and the learner perspective. There are less studies on the teacher view of blended learning environments. This study had the aim to explore, analyse and discuss teachers' perceived problems and barriers to a successful implementation of blended learning at university level.

    The used research strategy was a qualitative cross-sectional study where data has been collected with semi-structured interviews. Six teachers that all are subject matter experts and instructional designers for courses on computer science were interviewed. In a computer assisted thematic analysis found codes and keywords was grouped together to create themes.

    Four themes or problematic areas were found, and that they combined could give an explanation to what teachers experience as problems when implementing blended learning environments. First theme is documentation and support, where teachers find the scarcity of documentation in their virtual learning environment a problem for implementing extension modules. Second theme is introduction and training, where teachers find it problematic that they rarely get a proper introduction or further training on the use of tools and modules. Third theme is the time aspect, teachers suffer from the lack of time to implement blended learning thoroughly in their courses.  Last found theme is didactics, where teachers do not feel that they have the required knowledge or skills to apply the appropriate instructional design for blended learning environments.

    Depth-Based Inpainting For Disocclusion Filling2014In: 3DTV-Conference, IEEE Computer Society, 2014, p. Art. no. 6874752-Conference paper (Refereed)
    Abstract [en]

    Depth-based inpainting methods can solve disocclusion problems occurring in depth-image-based rendering. However, inpainting in this context suffers from artifacts along foreground objects due to foreground pixels in the patch matching. In this paper, we address the disocclusion problem by a refined depth-based inpainting method. The novelty is in classifying the foreground and background by using available local depth information. Thereby, the foreground information is excluded from both the source region and the target patch. In the proposed inpainting method, the local depth constraints imply inpainting only the background data and preserving the foreground object boundaries. The results from the proposed method are compared with those from the state-of-the art inpainting methods. The experimental results demonstrate improved objective quality and a better visual quality along the object boundaries.

    Managers basic assumptions when applying Lean2013In: 16th QMOD-ICQSS Proceedings: Quality Management and Organizational Development Conference [being] International Conference Quality and Service Sciences / [ed] Su Mi Dahlgaard-Park, Jens J. Dahlgaard, Boštjan Gomišček, 2013, p. 1206-1215Conference paper (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to present the result from a case study were managers where interviewed in order to find out their basic assumptions (i.e. purpose and underlying values) for applying Lean. The purpose is also to investigate if these basic assumptions are in line with what the literature describes as important for succeeding when applying Lean.

     

    Methodology/approach – Interviews based on an interview guide with open questions were carried out with managers in an organization.

    Findings – The study showed that the reason given for applying Lean are different between a manager that has started to apply Lean and a manager that has not yet started to apply Lean in their organization and that it is a difference between their basic assumptions.

     

    Originality/Value – The paper indicates the importance of knowing the managers’ values when applying Lean and the importance to educate managers’ to get a deeper understanding of Lean.

    Can Lean values contribute to Sustainable Development2014In: 17th Qmod-ICQSS: Part 2: INDEX and FULLPAPERS / [ed] Su Mi Dahlgaard-Park, Jens Jörn Dahlgaard, 2014Conference paper (Refereed)
    Abstract [en]

    Purpose – The aim of this paper was to study interactions between Sustainable Development and Lean values by comparing two organizations, one with Technical Communication in-house and one with Technical Communication partly outsourced.

    Methodology/approach – A literature study with focus on Lean and Sustainable Development values was carried out. Interviews with companies that provide Technical Communication have been conducted to identify Lean categories. The identified categories have been compared to the findings in Lean and Sustainable Development values.

    Findings – The literature study and our results indicate that presence of Lean values support Sustainable Development, but it requires that organizations focus on the culture and values. The result indicates that if Technical Communication has a low status the company put low value on Sustainable Development. If Technical Communication is produced in-house customer involvement might be easier to achieve.

    Practical implications – The identification of Lean values can be a starting point for organizations to work with Sustainable Development as it helps the organizations to focus on significant areas.

    Nätverk som stöd i små livsmedelsföretags kvalitetsarbete: En väg till Visionen Matlandet?2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    2008 lanserade Sveriges landsbygdsminister en vision om Sverige som det nya matlandet i Europa. Att arbeta mot denna vision skall ge ökad sysselsättning och nya företag inom de gröna näringarna är förhoppningen.

    Det finns i Sverige idag ca 3000 livsmedelsföretag varav ca 1300 enmansföretag men bara 650 företag med mer än 10 anställda.

    Det ställs krav på kvalitetssäkring inom livsmedelsföretag som inte ställs på många andra typer av företag. Hur arbetar då alla dessa småföretag med sitt kvalitetsarbete? I branschen är det traditionellt så att man har hjälpts åt genom arbete i kooperativa lösningar. Dessa har på senare år blivit så stora att flera av dem har sålts till andra större koncerner.

    Ett stort antal olika typer av nätverk har tidigare studerats växa fram i branschen och i detta arbete har detta fenomen studerats. Vilken nytta har de små livsmedelsproducenterna av sina nätverk? Kan de vara till hjälp i kvalitetsarbetet för dessa mindre företagare?

    Olika kvalitetsmodeller som Kanomodellen och PDCA-hjulet användes som teroetisk referensram när sedan 6 mindre livsmedelsproducenter med olika typer av produktion intervjuades.

    Traditionellt sett har livsmedelsproducenter i norra Europa setts som mest intresserade av kvalitetsarbete i form av kvalitetssystem och matsäkerhet och kvalitetsaspekter som regionalt ursprung och smak har ansetts som högre värderat i södra Europa.

    I denna studie visade sig ett annat mönster där de intervjuade företagarna betonade vikten av att leverera vad som enligt Kanomodellen mer betraktas som ”Attraktiv kvalitet” och att de lagstadgade kraven på kvalitetsystem visserligen var nödvändig kvalitet med bara tillfredsställde basbehoven och inte det som medförde kundtillfredsställelse.

    Analysis of Optical and Physical Dot Gain by Microscale Image Histogram and Modulation Transfer Functions2013In: Journal of Imaging Science and Technology, ISSN 1062-3701, E-ISSN 1943-3522, Vol. 57, no 2, p. 020504-1-020504-5Article in journal (Refereed)
    Abstract [en]

    The color of a print is affected by ink spreading and lateral light scattering in the substrate, making printed dots appear larger. Characterization of physical and optical dot gain is crucial for the graphic arts and paper industries. We propose a novel approach to separate physical from optical dot gain by use of a high-resolution camera. This approach is based on the histogram of microscale images captured by the camera. Having determined the actual physical dot shape, we estimate the modulation transfer function (MTF) of the paper substrate. The proposed method is validated by comparing the estimated MTF of 11 offset printed coated papers to the MTF obtained from the unprinted papers using measured and Monte Carlo simulated edge responses.
