    Elevinflytande i matematiken: Två pedagogers och fyra elevers perspektiv2012Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna undersökning var att ta reda på hur pedagoger och elever upplever

    elevinflytande i matematiken. Vi ville även undersöka om pedagogernas syn på

    elevinflytande stämde med det som står i styrdokumenten. En kvalitativ

    undersökning med intervjuer av två pedagoger och fyra elever samt observationer i

    pedagogernas klassrum genomfördes. Vårt resultat visade att elevinflytandet inte är

    stort inom matematiken men dock att pedagogerna och eleverna var nöjda med detta.

    Resultatet visade även att eleverna främst har inflytande över praktiska saker som

    exempelvis vilket material de använder. Gällande planeringen av

    matematikundervisningen visade resultatet att eleverna inte hade något inflytande i

    detta. Pedagogerna i denna undersökning ansåg att elevinflytande var något positivt

    men att de ansåg att det var för problematiskt inom matematiken för att kunna

    genomföra detta i praktiken. Detta gör att pedagogernas uppfattning gällande

    elevinflytande inte alltid stämde överens med styrdokumenten då pedagogerna ansåg

    att området var ett mål att sträva mot istället för ett genomgående arbetssätt

    Att möta företaget ur ett rumsligt perspektiv:  Hur rummet kan fungera som en informationslänk mellan företaget och besökaren.2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det här är ett examensarbete i informationsdesign med inriktning mot rumslig gestaltning. Syftet med detta examensarbete har varit att undersöka utvecklingsmöjligheterna för den rumsliga utformningen i X huvudentré, med målet om att rumsligt stärka informationslänken mellan företaget och besökare. Genom att skapa en förståelse för hur rummets gestaltning samspelar med människans upplevelse ges en större insikt i hur ett rum bör utformas för ett bestämt syfte, både för att kunna stödja en praktisk funktion och även en visuell upplevelse.

    Syftet med de undersökningar som utförts i examensarbetet har varit att få en uppfattning kring besökarnas upplevelse av den rumsliga utformningen i X huvudentré. Huruvida rummet som informationslänk fungerar mellan företag och besökare. Genom att använda mig av olika metoder såsom litteraturstudie, semistrukturerad intervju, observationer, notationer och enkäter kunde en bristande informativ länk konstateras. Med stöd av litteratur och olika forsknings- teorier har jag designat en modul där olika rumsliga element har inkluderats, för att på ett tydligare och mer integrerande sätt presentera företaget. Med modulens centrala placering skapas ett mer lättillgängligt informationsflöde i rummet. Modulens form och innehåll väcker besökarens intresse ”på vägen”. Det blir en central plats för information, där företaget genom sin moderna teknik kan förmedla nya projekt, sin visionsbild och på så sätt stärka sin image.

    Patienters upplevelser av empati hos läkare i läkar-patientmötet: Intervjuer med bröstcancerpatienter2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studien handlade om bröstcancerpatienters upplevelser av empati hos läkare i läkar-patientmötet.  Fokus låg på att undersöka i hur stor utsträckning läkarens empatiska förmåga bidrar till upplevelsen av god vård. Metoden var av kvalitativ ansats där semistrukturerade intervjuer utfördes med 12 bröstcancerdrabbade kvinnor. Resultatet gav kategorier tillhörande studiens tre frågeställningar. Frågeställningen om vad som utgör en empatisk läkare belystes av kategorierna (1) sätta sig in i den andres situation, (2) både känsla och handling, (3) kunskap, (4) informativ och (5) god lyssnare. Frågeställningen om icke-empatisk läkare belystes av kategorierna (1) dålig information, (2) opersonlig och (3) dålig förmåga att skapa god behandlingsallians. Frågeställningen om god vård belystes av (1) kontinuitet hos läkare, (2) bli sedd som individ och (3) mer tid hos läkare. I fall av brist på empati upplevde patienterna mindre grad av tillfredställande. God vård och empati är beroende av varandra, den ena kan inte existera utan den andre.

    Elevers upplevelser och habitus i relation till stödåtgärder och åtgärdsprogram: En studie i grundskolans nionde år2010Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Jag har genomfört en kvalitativ studie om elevens upplevelser och habitus i relation till att bli tilldelad ett åtgärdsprogram i år 9. Syftet är att ta reda på hur eleven och dess omgivning upplever det när eleven får ett åtgärdsprogram och vilka förväntningar både eleven och föräldrarna har. Genom öppna intervjuer har jag samlat in data från sex elever i en skola i Mellansverige. Min studie stöder sig mot Bourdieus teori om att individers värderingar och beteenden formas av sin närmaste omgivning. Resultatet visar att eleverna överlag blir motiverade att ta tag i sina studier för att nå ett godkänt betyg, förutsatt att de inte sedan tidigare har ett flertal åtgärdsprogram. I mina intervjuer framkommer det också att kompisgruppen känns som ett stöd där man kan ventilera sina tankar runt åtgärdsprogrammet samt att alla elever upplever att de har ett bra stöd hemifrån i sin strävan att nå godkända betyg.

    Vård i livets slutskede: Systematisk litteraturstudie om sjuksköterskors erfarenheter2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Vård i livets slutskede sker på på vårdavdelningar, i hemmet, inom primärvården, på hospice eller via hemtjänsten. I sitt dagliga arbete kommer allmänsjuksköterskor möta patienter som vårdas i livets slutskede. Den palliativa vårdfilosofin syftar till att lindra patienters lidande. Sjuksköterskor har den ledande rollen i omvårdnadsansvar för patienter. Syfte: Beskriva sjuksköterskors erfarenheter av att vårda patienter i livets slutskede. Metod: Kvalitativ ansats. Systematisk litteraturstudie med beskrivande syntes enligt Evans (2002). Resultat: Efter analysen framkom två teman och fem subteman. Tema 1) Otillräcklighet som inkluderar: Svårt att tillfredsställa behov och svårt att hålla personlig distans. Tema 2) Tillfredställelse som inkluderar: Meningsfullhet, stöd från teamet och förståelse. Slutsats: Sjuksköterskor erfar både positiva och negativa erfarenheter av att vårda patienter i livets slutskede. De positiva erfarenheterna framkommer när sjuksköterskor erfar sitt dagliga arbete som meningsfullt. De negativa erfarenheterna framkommer när sjuksköterskor erfar otillräcklighet. Relationen till patienter och dess anhöriga beskrivs som viktig för att höja vårdkvalitén. Relationen kan visa sig att medföra problem på sjuksköterskors personliga plan om de identifierar sig med vårdtagarna.

    Affinity binding of inclusion bodies on supermacroporous monolithic cryogels using labeling with specific antibodies.2006In: Journal of Biotechnology, ISSN 0168-1656, Vol. 122, no 2, p. 216-225Article in journal (Refereed)
    Abstract [en]

    A new chromatographic method based on affinity supermacroporous monolithic cryogels is developed for binding and analyzing inclusion bodies during fermentation. The work demonstrated that it is possible to bind specific IgG and IgY antibodies to the 15 and 17 amino acids at the terminus ends of a 33kDa target protein aggregated as inclusion bodies. The antibody treated inclusion bodies from lysed fermentation broth can be specifically retained in protein A and pseudo-biospecific ligand sulfamethazine modified supermacroporous cryogels. The degree of binding of IgG and IgY treated inclusion bodies to the Protein A and sulfamethazine gels are investigated, as well as the influence of pH on the sulfamethazine ligand. Optimum binding of 78 and 72% was observed on both protein A and sulfamethazine modified cryogel columns, respectively, using IgG labeling of the inclusion bodies. The antibody treated inclusion bodies pass through unretained in the sulfamethazine supermacroporous gel at pH that does not favour the binding between the ligand on the gel and the antibodies on the surface of inclusion bodies. Also the unlabeled inclusion bodies went through the gel unretained, showing no non-specific binding or trapping within the gel. These findings may very well be the foundation for the building of a powerful analytical tool during fermentation of inclusion bodies as well as a convenient way to purify them from fermentation broth. These results also support our earlier findings [Kumar, A., Plieva, F.M., Galaev, I.Yu., Mattiasson, B., 2003. Affinity fractionation of lymphocytes using a monolithic cyogel. J. Immunol. Methods 283, 185-194] with mammalian cells that were surface labeled with specific antibodies and recognized on protein A supermacroporous gels. A general binding and separation system can be established on antibody binding cryogel affinity matrices.

    Supporting pre-development of new manufacturing technologies2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    In today’s tough industrial environment, efficient development of new products and new manufacturing solutions is necessary to stay competitive on a global market. Manufacturing companies use substantial money and development resources to develop new products. However, the resources spent on finding and implementing emerging manufacturing technologies are much more limited. This is often the case even though it is well known that a way of competing on a global market is through the introduction of new manufacturing technologies that can improve product quality as well as contribute to reducing manufacturing time, resulting in reduced product price and in the end increased profit.

    When introducing new manufacturing technologies, different challenges arise such as lack of knowledge, involvement of an external equipment supplier, etc. In addition, time-to-volume is critical when introducing new manufacturing technologies in a manufacturing context. To be able to have a fast ramp-up, manufacturing technology needs to be mature enough and at the same time meet all requirements. Efficient introduction of new manufacturing technologies requires that pre-development activities have been performed in advance.

    Previous research in this area highlights a lack of knowledge and solutions regarding pre-development of new manufacturing technologies. Such pre-development is important in order to have a successful introduction, fast time-to-volume and production system development. Based on these challenges, the objective of the research presented in this thesis is to develop support for pre-development of new manufacturing technologies.

    The research is based on literature reviews and three empirical case studies, carried out over a two-year period of time. The first empirical case study was an exploratory case study in the manufacturing industry. The purpose of that research study was to identify critical factors forcing manufacturing companies to improve the development of manufacturing technologies.

    The second study was a longitudinal embedded case study in the manufacturing industry with the purpose of identifying factors that affect evaluation of new manufacturing technologies during new product development. Particular attention was given to the product development process and how it has affected the evaluation of new manufacturing technologies.

    Finally, the third study was a single case study in the manufacturing industry with the purpose of analysing and discussing the assessment of the maturity level of a manufacturing technology.

    The fuzzy front end of manufacturing technology development: Exploring the link between the known and the unknown2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    It is well known that a way of competing on a global market is through the introduction of new manufacturing technologies in the production system that can improve product quality as well as contribute to reducing manufacturing time, reduced product price and in the end increased profits. Manufacturing companies that develop and introduce new manufacturing technologies can differentiate themselves from others and thus achieve increased competitiveness.

    The fuzzy front end of manufacturing technology development is characterized by a high degree of technology uncertainty and challenges due to the lack of access to relevant knowledge, lack of a structured development process, and enough resources that are working with development of new manufacturing technologies.

    In the literature only a few empirical studies that explore the fuzzy front end of manufacturing technology development can be found. Prior research highlights that little is actually known about what should be done in the fuzzy front end of manufacturing technology development projects, and thus more research is needed. Supporting the fuzzy front end of manufacturing technology development is important to facilitate a successful introduction of new manufacturing technologies, fast time-to-volume and long-term production system development.

    Based on the above-mentioned importance of developing new manufacturing technology, the objective of the research presented in this thesis is to explore the fuzzy front end of manufacturing technology development. In order to fulfil the objective, empirical data were collected from five case studies conducted in the manufacturing industry. During the empirical studies four important parts were studied: organising, knowledge development, collaboration and the development process.

    The main findings revealed that development of new manufacturing technology is often conducted in collaboration with external partners and many ad hoc decisions are taken due to lack of a predefined development process for the fuzzy front end of manufacturing technology development. In addition, in the fuzzy front end access to relevant manufacturing knowledge is important and knowledge needs to be developed in order to reduce technology uncertainty.

    In order to support the fuzzy front end of manufacturing technology development projects, a supporting framework has been developed. The proposed framework is an elaboration of results from the research questions addressed and can be used as a guideline to overcome the challenges observed in the fuzzy front end of manufacturing technology development projects. The framework is built on two important dimensions for innovations, degree of technology uncertainty and degree of novelty. The critical factors identified in the analysis are embedded in the proposed framework as central parts in the fuzzy front end of manufacturing technology development.

    Evaluation of Advanced Manufacturing Technology during New Product Development2014In: The 21st EurOMA Conference EurOMA 2014, Palermo, Italy, 2014Conference paper (Refereed)
    Abstract [en]

    The purpose of this paper is to identify factors that affect evaluation of advanced manufacturing technology (AMT) during new product development (NPD). Particular attention is given to the new product development process and how it has affected the acquisition and evaluation process of AMT. An embedded case study has been conducted at a large Swedish manufacturing company, consisting of semi structured interviews, document analysis, and passive observations. This paper identifies seven factors that affect the evaluation of AMT during NPD and which can be classified into three categories: NPD project, AMT acquisition project and the internal organization.

    FACTORS AFFECTING DEVELOPMENT OF PRODUCTION TECHNOLOGIES IN A MACHINING ENVIRONMENT2014In: Tools and Methods of Competitive Engineering 2014 TMCE 2014, 2014Conference paper (Refereed)
    Abstract [en]

    The purpose of this paper is to identify critical factors forcing manufacturing companies to improve the development of production technology in a machining environment. The focus in the paper is on industrial challenges within product design and production system development when introducing new products in a machining environment. Particular attention is given to the product development process and the production equipment acquisition process. A single case study is presented, consisting of interviews, observations, document studies and an analysis of a large Swedish manufacturing company. The case study company is characterized by advanced production technology, high mechanization and high automation level. In parallel with the case study a literature review was conducted in order to identify state-of-the-art methods/models for efficient design and product introduction within a production system. The paper identifies a gap in the current way of working within the case company as well as challenges regarding the development of production technology. Based on the study, the need for future research has been identified including the need of developing an improved working support for efficient production technology development when industrializing new products.

    Knowledge integration in manufacturing technology development2017In: Journal of Manufacturing Technology Management, ISSN 1741-038X, E-ISSN 1758-7786, Vol. 28, no 8, p. 1035-1054Article in journal (Refereed)
    Abstract [en]

    Purpose - The purpose of this paper is to identify and analyze knowledge integration in manufacturing technology development projects required to build competitive advantages. Design/methodology/approach - A longitudinal case study has been conducted at a Swedish manufacturing company by following a manufacturing technology development project in real time during a two-year period. Findings - The results show that three different knowledge integration processes exist when developing unique manufacturing technology: processes for capturing, for joint learning, and for absorb learning. The findings of the current research suggest that the three knowledge integration processes are highly interrelated with each knowledge integration process affecting the other two. Research limitations/implications - The major limitation of the research is primarily associated with the single case, which limits generalizability outside the context that was studied. Practical implications - The findings are particularly relevant to manufacturing engineers working with the development of new manufacturing technologies. By using relevant knowledge integration processes and capabilities required to integrate the knowledge in manufacturing technology development projects, companies can improve design and organize the development of manufacturing technology. Originality/value - Previous research has merely noted that knowledge integration is required in the development of unique manufacturing technology, but without explaining how and in what way. This paper's contribution is the identification and analysis of three knowledge integration processes that contribute to the building of competitive advantages by developing unique manufacturing technology and new knowledge.

    What makes registered nurses remain in work?: An ethnographic study2019In: International Journal of Nursing Studies, ISSN 0020-7489, E-ISSN 1873-491X, Vol. 89, p. 32-38Article in journal (Refereed)
    Abstract [en]

    Background: Registered nurses’ work-related stress, dissatisfaction and burnout are some of the problems in the healthcare and that negatively affect healthcare quality and patient care. A prerequisite for sustained high quality at work is that the registered nurses are motivated. High motivation has been proved to lead to better working results. The theory of inner work life describes the dynamic interplay between a person's perceptions, emotions and motivation and the three key factors for a good working life: nourishment, progress and catalysts. Objectives: The aim of the study was to explore registered nurses’ workday events in relation to inner work life theory, to better understand what influences registered nurses to remain in work. Design: A qualitative explorative study with an ethnographic approach. Methods: Participant observation over four months; in total 56 h with 479 events and 58 informal interviews during observation; all registered nurses employed at the unit (n = 10) were included. In addition, individual interviews were conducted after the observation period (n = 9). The dataset was analysed using thematic analysis and in the final step of the analysis the categories were reflected in relation to the three key factors in theory of inner work life. Results: Nourishment in a registered nurse context describes the work motivation created by the interpersonal support between colleagues. It was important to registered nurses that physicians and colleagues respected and trusted their knowledge in the daily work, and that they felt comfortable asking questions and supporting each other. Progress in the context of registered nurses’ work motivation was the feeling of moving forward with a mix of small wins and the perception of solving more complex challenges in daily work. It was also fundamental to the registered nurses’ development through new knowledge and learning during daily work. Catalysts, actions that directly facilitate the work, were highlighted as the possibility to work independently along with the opportunity to work together with other registered nurses. Conclusion: This study has a number of implications for future work and research on creating an attractive workplace for registered nurses. Working independently, with colleagues from the same profession, integrated with learning, visible progress, and receiving feedback from the work itself, contribute to work motivation.

    Lärares argument för användande av olika läromedel i matematikundervisningen2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att undersöka vilka argument lärare anger för att använda olika läromedel i matematikundervisningen i årskurs 1-3. För att få fram lärares tankar, argument och syften med användningen av olika läromedel skedde datainsamlingen genom intervjuer med fyra verksamma lärare. De läromedelstyper som berördes var läroböcker, konkret material och digitala verktyg. Utifrån litteraturgenomgången och intervjusvaren arbetades sju kategorier av argument fram: genomgång, skapa förståelse, färdighetsträning, individualisering, planering, motivation och komplettering. De sju kategorierna motsvarade olika argument lärare har för användningen av olika läromedelstyper. Resultatet antyder att läroböcker ofta används för att ligga till grund för undervisningen och konkret material används ofta för att konkretisera matematiken för eleverna. I resultatet framkommer det att argumenten för användning av digitala verktyg varierar beroende på vilken typ av digitalt verktyg det är. Studiens slutsats är att en läromedelstyp kan användas med många olika syften och att olika lärare kan ha olika argument för att använda samma läromedelstyp.

    Computer Controlled Direct Descent2017Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    How an aircraft performs its approach and descent towards an airport today has got big potential for improvements. It's mainly the environmental impact and safety that can, and must, be improved for a sustainable future in aviation. "Green Approaches" is a small, yet relatively well-known, optimized approach system mainly used by Scandinavian Airlines on Arlanda airport. Unfortunately "Green Approaches" aren't used often enough, due to the simple reason that it doesn't work very well during heavy traffic. Luckily further research is being done in this field to further optimize an aircraft’s approach. As of today, the most forward going research is being done by the FAA and NASA, and their new system is called NextGen OPD. The system is not fully developed yet but their goals are, as previously mentioned, to optimize today's aircraft approach. In this report the focus will also be set on improving aircraft approaches, although not by optimizing today’s system like the FAA and NASA. Instead, a whole new concept of how aircraft approach airports will be developed. The reason that a brand new concept will be developed is simple, optimizing today's aging system will not be sustainable for the future. Also, optimizing an aging system has its limits. By designing a whole new concept, a steady ground will be laid and it shall be sustainable for the coming century's technology. The new concept will be called ”C.C.D.D.”, Computer Controlled Direct Descent, and will have a lot of goals and expectations to fulfill. As hinted in the name, the new concept is built on the idea that a computer will be controlling the whole approach, and therefore the "Human factor" will more or less be eliminated. Although the main purpose of a new approach system is to decrease the negative environmental impact, by decreasing the fuel consumption during the approach. The new concept will also decrease the noise an aircraft makes during the descent and increase the possibility for a greater traffic flow in the airport’s airspace. The end result will be a "win-win" for everyone involved. An environmentally friendly aircraft approach is necessary for a sustainable future in aviation. C.C.D.D. is a system that will pay for itself with time, because of the decreased fuel consumption for airliners. The system also has the ability to be expanded to computer control departing aircrafts, due to the systems highly computerized structure and integration with airplanes autopilot.

    Konflikten mellan arbetsliv och familjeliv: En kvalitativ studie om småbarnsföräldrars upplevelser av psykisk hälsa och balans i tillvaron2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today's career choices and ambitions impose different demands on the individuals than in the past. In a labour market that demands flexibility and responsibility, the individuals are expected to be able to work almost anytime and from anywhere. These factors have contributed to an imbalance between work and family life that can trigger various forms of illness. In this study, I investigate how parents of young children perceive their mental health in relation to the balance between work and family life. This is achieved through a study that employs qualitative methods and data collection based on six individual semi-structured interviews, where the material is then analysed based on a manifest content analysis. The results show that today’s parents are well aware of the imbalance between their work and family life, and that this negatively affects their health in several ways, ranging from stress and anxiety to sleep problems and personal conflicts. To address this imbalance the parents creates routines, shared responsibilities at home, and allow personal time for leisure, in an attempt to create a form of control over this imbalance. The conclusion of this study is that parent’s experience that they have to have routines at work and family life, where the parents have lower demands on their own health.

    Abstract [en]

    This report is written during a project done by two students at Mälardalen University during the course DVA331. The purpose of this project was to determine if it was possible to reduce the latency on devices with Windows 10 to what is possible on an iOS device. The reason behind this research is that Windows 10 has come with an API that supports low latency sounds. This study was made on an iPhone 4S, iPhone 6, Nokia Lumia 720 and a Nokia Lumia 920 with a contact microphone that was put on the device. The latency was measured 50 times per version of an application implemented for both operating systems. The latency could be measured between the point where the surface is touched and and the point where sound is audible, using the microphone and the audio processing software Audacity. The readings proved that iOS is still a lot faster than Windows 10 and that Windows 10 is way above the accepted audio processing limit. Further research showed that the Windows 10 reading results were caused by the Lumia devices long input latency. User tests were made on 10 individuals with the response that the latency on the Windows 10 devices was a lot longer than the iOS devices. The conclusion was that the Lumia devices used in this study were not suitable for responsive sound applications but that Windows 10 devices with lower input latency that are better suited and that new readings should be done to determine if this is the case.

    A Code Generator for Software Component Services in Smart Devices2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    A component is built to be reused and reusability has significant impact on component generality and flexibility requirement. A component model plays a critical role in reusability of software component and defines a set of standards for component implementation, evolution, composition, deployment and standardization of the run-time environment for execution of component. In component based development (CBD), standardization of the runtime environment includes specification of component’s interfaces – general and domain specific run-time services. For rapid development of component based system for distributed information systems, COM+ and .NET technologies introduced the idea of Software Component Services that are achieved by proxy objects which intercept message calls between components to provide service like transaction handling, security management, etc.

    An embedded real-time system (ERTS) designed for a specific purpose in which software tasks have hard real-time constraints to execute and it interact directly with its environment via buses, sensors and other devices. In an embedded real time system, it is great importance to ensure that all tasks of the software system should respond within the time limits. Component based development process have vital role in development of embedded real time system and recently software component models applied in the embedded real-time systems (ERTS) and introduced software component services (SCS) for ERTS.

    The purpose of this Master thesis is to investigate how to make tool that targets smart device projects in Microsoft Visual Studio and generates proxy objects that can be compiled with Microsoft Visual Studio.NET. The tool generates a complete set of files for a Microsoft Visual Studio smart device project within solution, including both source code and configuration files according to a specific version of Visual Studio by invoking Visual Studio’s automation object model. The tool also generates code for simple logging services for the .NET component running on top of the .NET Compact framework.

    Continuing Airworthiness Management Exposition: For Priority Aero Maintenance2012Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The economic crisis has affected the airline industry as much as it has affected all other industries in the world. The small airlines and maintenance organisations must find new opportunities and options in order to survive the harsh crisis. Priority Aero Maintenance is now an approved maintenance organisation performing maintenance on aircrafts, engines and components. The company sees economic gains in the future by becoming an approved organisation that follows the European Aviation Safety Agency guidelines (EASA) and meets the requirements outlined in the rules of Part-M.

    In order for the company to become an approved organization, responsible for continuing airworthiness of aircraft, a handbook should be presented to the local authority. This handbook describes the company’s responsibility for the continuing airworthiness in order for the authorities to get an insight into the company and its work.

    This thesis resulted in a draft of CAME (Continuing Airworthiness Management Exposition) and this draft has been approved by Priority Aero Maintenance.

    The CAME will in the future be used by the company as a basis for developing a more detailed manual to be presented to and approved by the Swedish Aviation Authority (Transportstyrelsen).

    Abstract [en]

    Computer-Supported Cooperative Work (CSCW) relates to working in group by distance using computer-based systems and aims to achieve the optimal efficiency in the group's working process. Such systems include computersupported collaborative sketching system. In interaction design, there is an interest in sketch collaboration on digital systems. We have therefore chosen, within the frame of this work, to investigate whether collaborative sketching using digital platform applications lead to an effective way of working for designers and what functionalities such applications should include. To get answers to our questions, we have chosen to create an Android as well as a Web application for sketch collaboration. In our applications we have considered the designers' wishes regarding functionalities. The applications were used in a research to be able to analyze how designers collaborate on digital platforms. Our results have proven that collaborative sketching on digital platforms is a smooth and mobile way of working which involves active discussions, creating new ideas and better solutions, contributes to knowledge transfer and a better working environment and interaction between designers.

    Diversity barometer: attitude changes in SwedenIn: Nordic Social Work Research, ISSN 2156-857X, E-ISSN 2156-8588Article, review/survey (Refereed)
    Abstract [en]

    he aim of this article is to elucidate and discuss the results of the 2016 Diversity Barometer (Mångfaldsbarometern) and compare these results with those obtained from ten years of the longitudinal Diversity Barometers for 2005?2014. An additional aim is to demonstrate whether and how Swedish people?s experiences of and attitudes toward people with a foreign background and ethnic diversity have changed.A random sample of the Swedish population took part in the annual study, which was carried out in the form of a nationwide postal survey. The results show that negative attitudes toward ethnic and cultural diversity in general, and migrant population in particular, have increased to some extent and with respect to certain issues. Views on diversity in relation to culture and religion ? especially Islam ? were more negative than views on diversity in relation to work. Those who have larger experience of contact with foreigners show a more positive attitude toward diversity compared with those with limited experience and contact. Individuals who have higher education, those who identify themselves as female, younger persons and those living in large cities are more positive than other groups. In our analysis of the empirical data, we proceeded from a social work perspective and applied contact theory and group conflict theories relating attitudes to group position.

    The application of system dynamics and discrete event simulation in supply chain management of Swedish manufacturing industries2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Increasing competition from traditional and emerging channels has placed new emphasis on rapid innovation and continuous differentiation in every aspect of supply chain, from earliest production stage to the final distribution steps. To bridge the gap between brilliant ideas and successful business initiatives, leading companies implement engineering simulation particularly in logistics and supply chain management (LSCM). Discrete event simulation (DES) and system dynamics (SD) are two modeling approaches widely used in this field. However there are not much done researches about the applications of these simulation approaches in supply chain context of Swedish Manufacturing Industries (SMI). This study explores the application of DES and SD in LSCM of SMI by looking at the nature and level of issues modeled. Journal papers and master theses that use these modeling approaches to study supply chains, published between 1990 and 2012 are reviewed. A total of 39 articles are analyzed to identify the frequency with which the two simulation approaches are used as modeling tools in LSCM of SMI. Our findings suggest that DES has been used more frequently to model supply chains in SMI. The results also show that not all the LSCM issues have been addressed evenly and generally tactical/operational issues have been modeled more frequently. The results of this study inform the existing literature about the use of DES and SD in LSCM of SMI.

    Abstract [en]

    Self-compacting concrete has soon been around for a decade. Recently the prefabrication industry has started to use this fairly new concrete type in larger scales, mainly because of its distinctive properties.  There are still certain areas that need to be thoroughly examined, such as bond capacity. There have been very few studies regarding shear capacity due to the fact that the procedure is complicated.

    This report will highlight a method to examine the shear capacity of different surfaces that have been prewetted as well as non-prewetted surfaces. The surface areas follow BBK 04’s and Eurocode 2’s demand for surface roughness.  A smooth surface will be completed in order to confirm if the different shapes influence the bond strength by shear stress or not.                       

    The purpose of this essay is to measure the bond strength within the shear capacity as well as examine the impact it has on surface roughness and treatment for shear bond.

    The method used to identify the shear capacity is called L-shaped Push-Off Test. The dimension of the object was selected with the help of a previous research paper. The Sand-Patch method is predominantly used to measure the surface roughness. 

    The results showed no difference between the demands of surfaces of BBK04 and Eurocode 2 considering the shear capacity. However the non-prewetted surface was measured with the highest shear capacity value. Apart from the shear strength, deformation was measured in both vertical and horizontal direction and it was clearly shown that the vertical deformation was measured to be ten times higher than the horizontal deformation.  There was no difference between the BBK 04 and Eurocode 2 considering the vertical deformation. However the difference occurred on the horizontal direction between BBK 04 and Eurocode 2 where the specimens of Eurocode 2 received three times higher deformation compared to BBK 04. The conclusion can be drawn that the surface roughness of BBK 04 would be more suitable than eurocode2 considering deformation.     

    The overall result was that the surface treatment with the demands of BBK 04 and Eurocode 2 showed minor difference after being measured with the Push-Off Test method. This has been confirmed with the estimated shear capacity (1.2 MPa). The results revealed that the treatment of surface could be made in either way, brush or rake. As a conclusion the assessment of the shear strength showed that Eurocode 2's demand is too strict comparing demands of BBK 04.

    Diagnosing the Cause and Its Timing of Changes in Multivariate Process Mean Vector From Quality Control Charts Using Artificial Neural Network2011In: World Academy of Science, Engineering and Technology: An International Journal of Science, Engineering and Technology, ISSN 2010-376X, E-ISSN 2070-3740, Vol. 5, no 6, p. 212-217Article in journal (Refereed)
    Abstract [en]

    Quality control charts are very effective in detecting out of control signals but when a control chart signals an out of control condition of the process mean, searching for a special cause in the vicinity of the signal time would not always lead to prompt identification of the source(s) of the out of control condition as the change point in the process parameter(s) is usually different from the signal time. It is very important to manufacturer to determine at what point and which parameters in the past caused the signal. Early warning of process change would expedite the search for the special causes and enhance quality at lower cost. In this paper the quality variables under investigation are assumed to follow a multivariate normal distribution with known means and variance-covariance matrix and the process means after one step change remain at the new level until the special cause is being identified and removed, also it is supposed that only one variable could be changed at the same time. This research applies artificial neural network (ANN) to identify the time the change occurred and the parameter which caused the change or shift. The performance of the approach was assessed through a computer simulation experiment. The results show that neural network performs effectively and equally well for the whole shift magnitude which has been considered.

    Multi criteria decision making with Evidential Reasoning under uncertainty2016In: IEEE International Conference on Industrial Engineering and Engineering Management, 2016, p. 1534-1538Conference paper (Refereed)
    Abstract [en]

    Many decision problems have more than one objective that need to be dealt with simultaneously. Moreover, because of the qualitative nature of the most of real world problem it is an inevitable activity and very important to interpret and present the uncertain information for making effective decision. The Evidential Reasoning (ER) approach which is one of the latest development within multi criteria decision making (MCDM) seems to be the best fit to synthesize both qualitative and quantitative data under uncertainty. To support this claim, two case studies were tested to illustrate the application of ER for prioritization and ranking of decision alternative to support decision process even with uncertain information. The importance of having a better structured decision process is essential for the success of any organization, so it can be applied widely in most of real world problem dealing with making effective decision.

    Abstract [en]

    Many decision problems have more than one objective that need to be dealt with simultaneously. Moreover, because of the qualitative nature of the most of real world problem it is an inevitable activity and very important to interpret and present the uncertain information for making effective decision. The Evidential Reasoning (ER) approach which is one of the latest development within multi criteria decision making (MCDM) seems to be the best fit to synthesize both qualitative and quantitative data under uncertainty. To support this claim, two case studies were tested to illustrate the application of ER for prioritization and ranking of decision alternative to support decision process even with uncertain information. The overall goal of the first case study is to identify and prioritize factors that can be considered maintenance-related waste within the automotive manufacturing industry. The result after applying ER shows “inadequate resources” and “weather /indoor climate,” respectively, are the highest and lowest average scores for creating maintenance-related waste. This prioritization methodology can be used as a tool to create awareness for managers seeking to reduce or eliminate maintenance-related waste. The aim of the second case study is to look at the possibility of having a new approach for sustainable design. So through a literature review six design strategies were taken into consideration in order to develop a new approach based on all advantages (sustainable factors) of the six approaches. For ranking and finding out about the most important factors the evidential reasoning (ER) approach is used. Based on ER all the important factors, apart from the one collected from interviews are a part of eco-design. So it means among all strategies eco-design is the most dominant strategy in term of environment. However two of the important factors are not found in any strategy but in interviews. These factors can be used as the building blocks for a new approach. The importance of having a better structured decision process is essential for the success of any organization, so it can be applied widely in most of real world problem dealing with making effective decision.

    Classification of Maintenance-Related Waste Based on Human Factors2015In: 22nd International Annual EurOMA Conference EurOMA15, Neuchâtel, Switzerland, 2015Conference paper (Refereed)
    Abstract [en]

    The goal of this research is to identify and classify factors creating maintenance-related waste. A workshop study has been performed in order to identify root-causes for maintenance-related waste. In total, 16 categories were found in the analysis and it is concluded that these are heavily reliant on human factors as a root- or major contributory cause. These, together with factors based on a literature review have been incorporated into a classification model. The model can be used in creating awareness in, as well as provide a basic framework for decision making of, which waste to target for elimination.

    Using evidential reasoning approach for prioritization of maintenance-related waste caused by human factors-a case study2017In: The International Journal of Advanced Manufacturing Technology, ISSN 0268-3768, E-ISSN 1433-3015, Vol. 90, no 9-12, p. 2761-2775Article in journal (Refereed)
    Abstract [en]

    The reduction and elimination of maintenance-related waste is receiving increasing attention because of the negative effect of such waste on production costs. The overall goal of this research is to identify and prioritize factors that can be considered maintenance-related waste within the automotive manufacturing industry. Five manufacturing companies participated in a workshop to identify root causes of maintenance-related waste; 16 categories were found. The identified factors were heavily reliant on human factors as a root or major contributory cause at different levels affecting performance and productivity. For prioritization, the evidential reasoning (ER) approach which is one of the latest developments in multi-criteria decision-making is applied. A basic tree structure necessary for ER assessment is developed based on the workshop results as well as literature on human factors. Then, a survey on basic attributes at the lowest level of this tree is designed and performed at one of the companies participating in the workshop. The application of ER shows that, on an overall level, "management condition" is in first order and "maintainer condition" and "working condition" are in second and third order respectively as the worst cases for creating maintenance-related waste. On the most delimited level "inadequate resources" and "weather/indoor climate" have the highest and lowest average scores respectively in ER ranking or prioritization. This methodology with its resulting ranking can be used as a tool to create awareness for managers seeking to reduce or eliminate maintenance-related waste.

    Risk Prioritization Based on Health, Safety and Environmental Factors by Using Fuzzy FMEA2013In: International Journal of Mining, Metallurgy & Mechanical Engineering, ISSN 2320-4052, Vol. 1, no 4, p. 233-237Article in journal (Refereed)
    Abstract [en]

    Failure Mode and Effects Analysis is assessing technique which relies to the rule of preventing failure, which is used to identify potential hazards. This method is used with minimum risks to predict the problems and deficits in design stage or development of the processes and services in organizations. The methods main principal is based on multiplying three main parameters: severity, occurrence, detection. This method with all the advantages still has minor disadvantages that in this paper attempts has been made to eliminate these deficiencies by fuzzification. Results show that fuzzy FMEA will enables us to evaluate situations correctly and precisely.

    AN INVESTIGATION OF THE MOST IMPORTANT FACTORS FOR SUSTAINABLE PRODUCT DEVELOPMENT USING EVIDENTIAL REASONING2017In: Numerical Algebra, Control and Optimization, ISSN 2155-3289, E-ISSN 2155-3297, Vol. 7, no 4, p. 435-455Article in journal (Refereed)
    Abstract [en]

    Those working in product development need to consider sustain ability, being careful not to compromise the future generations ability to satisfy its needs. Several strategies guide companies towards sustainability. This paper studies six of these strategies: eco-design, green design, cradle-to-cradle, design for environment, zero waste, and life cycle approaches. Based on a literature review and semi-structured interviews, it identifies 22 factors of sustainability from the perspective of manufacturers. The purpose is to determine which are the most important and to use them as a foundation for a new design strategy. A survey based on the 22 factors was given to people working with product development; they graded each factor by importance. The resulting qualitative data were analyzed using evidential reasoning. The analysis found the factors minimize use of toxic substances, increase competitiveness, economic benefits, reduce material usage, material selection, reduce emissions, and increase product functionality are more important and should serve as the foundation for a new approach to sustainable product development.

    Remaining useful life prediction of grinding mill liners using an artificial neural network2013In: Minerals Engineering, ISSN 0892-6875, E-ISSN 1872-9444, Vol. 53, p. 1-8Article in journal (Refereed)
    Abstract [en]

    Knowing the remaining useful life of grinding mill liners would greatly facilitate maintenance decisions. Now, a mill must be stopped periodically so that the maintenance engineer can enter, measure the liners' wear, and make the appropriate maintenance decision. As mill stoppage leads to heavy production losses, the main aim of this study is to develop a method which predicts the remaining useful life of the liners, without needing to stop the mill. Because of the proven ability of artificial neural networks (ANNs) to recognize complex relationships between input and output variables, as well as its adaptive and parallel information-processing structure, an ANN has been designed based on the various process parameters which influence wear of the liners. The process parameters were considered as inputs while remaining height and remaining life of the liners were outputs. The results show remarkably high degree of correlation between the input and output variables. The performance of the neural network model is very consistent for data used for training (seen) and testing (unseen).

    Application of multi regressive linear model and neural network for wear prediction of grinding mill liners2013In: International Journal of Advanced Computer Sciences and Applications, ISSN 2158-107X, E-ISSN 2156-5570, Vol. 4, no 5, p. 52-58Article in journal (Refereed)
    Abstract [en]

    The liner of an ore grinding mill is a critical component in the grinding process, necessary for both high metal recovery and shell protection. From an economic point of view, it is important to keep mill liners in operation as long as possible, minimising the downtime for maintenance or repair. Therefore, predicting their wear is crucial. This paper tests different methods of predicting wear in the context of remaining height and remaining life of the liners. The key concern is to make decisions on replacement and maintenance without stopping the mill for extra inspection as this leads to financial savings. The paper applies linear multiple regression and artificial neural networks (ANN) techniques to determine the most suitable methodology for predicting wear. The advantages of the ANN model over the traditional approach of multiple regression analysis include its high accuracy.

    Remaining useful life estimation: Review2014In: International Journal of Systems Assurance Engineering and Management, ISSN 0975-6809, E-ISSN 0976-4348, Vol. 5, no 4, p. 461-474Article, book review (Other academic)
    Abstract [en]

    This paper reviews the recent modelling developments in estimating the remaining useful life (RUL) of industrial systems. The RUL estimation models are categorized into experimental, data driven, physics based and hybrid approaches. The paper reviews some typical approaches and discusses their advantages and disadvantages. According to the literature, the selection of the best model depends on the level of accuracy and availability of data. In cases of quick estimations which are less accurate, the data driven method is preferred, while the physics based approach is applied when the accuracy of estimation is important.

    Multivariate process parameter change identification by neural network2013In: The International Journal of Advanced Manufacturing Technology, ISSN 0268-3768, E-ISSN 1433-3015, Vol. 69, no 9-12, p. 2261-2268Article in journal (Refereed)
    Abstract [en]

    Whenever there is an out-of-control signal in process parameter control charts, maintenance engineers try to diagnose the cause near the time of the signal which does not always lead to prompt identification of the source(s) of the out-of-control condition, and this in some cases yields to extremely high monetary loses for the manufacturer owner. This paper applies multivariate exponentially weighted moving average (MEWMA) control charts and neural networks to make the signal identification more effective. The simulation of this procedure shows that this new control chart can be very effective in detecting the actual change point for all process dimension and all shift magnitudes considered. This methodology can be used in manufacturing and process industries to predict change points and expedite the search for failure causing parameters, resulting in improved quality at reduced overall cost. This research shows development of MEWMA by usage of neural network for identifying the step change-point and the variable responsible for the change in the process mean vector.

    Optimum design of PIλDμ controller for an automatic voltage regulator system using combinatorial test design2016In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 11, no 11, article id e0166150Article in journal (Refereed)
    Abstract [en]

    Combinatorial test design is a plan of test that aims to reduce the amount of test cases systematically by choosing a subset of the test cases based on the combination of input variables. The subset covers all possible combinations of a given strength and hence tries to match the effectiveness of the exhaustive set. This mechanism of reduction has been used successfully in software testing research with t-way testing (where t indicates the interaction strength of combinations). Potentially, other systems may exhibit many similarities with this approach. Hence, it could form an emerging application in different areas of research due to its usefulness. To this end, more recently it has been applied in a few research areas successfully. In this paper, we explore the applicability of combinatorial test design technique for Fractional Order (FO), Proportional-Integral-Derivative (PID) parameter design controller, named as FOPID, for an automatic voltage regulator (AVR) system. Throughout the paper, we justify this new application theoretically and practically through simulations. In addition, we report on first experiments indicating its practical use in this field. We design different algorithms and adapted other strategies to cover all the combinations with an optimum and effective test set. Our findings indicate that combinatorial test design can find the combinations that lead to optimum design. Besides this, we also found that by increasing the strength of combination, we can approach to the optimum design in a way that with only 4-way combinatorial set, we can get the effectiveness of an exhaustive test set. This significantly reduced the number of tests needed and thus leads to an approach that optimizes design of parameters quickly. © 2016 Ahmed et al.

    Handling Constraints in Combinatorial Interaction Testing in the Presence of Multi Objective Particle Swarm and Multithreading2017In: Information and Software Technology, ISSN 0950-5849, E-ISSN 1873-6025, Vol. 86, no 01, p. 20-36Article in journal (Refereed)
    Abstract [en]

    Combinatorial strategies have received a lot of attention lately as a result of their diverse applications in areas of research, particularly in software engineering. In its simple form, a combinatorial strategy can reduce several input parameters (configurations) of a system into a small set of these parameters based on their interaction (combination). However, in practice, the input configurations of software systems are subjected to constraints, especially highly configurable systems. To implement this feature within a strategy, many difficulties arise for construction. While there are many combinatorial interaction testing strategies nowadays, few of them support constraints. This paper presents a new strategy, called Octopus to construct a combinatorial interaction test suites with the presence of constraints. The design and algorithms are provided in the paper in detail. The strategy is inspired by the behaviour of octopus to search for the optimal solution using multi-threading mechanism. To overcome the multi judgement criteria for an optimal solution, the multi-objective particle swarm optimisation is used. The strategy and its algorithms are evaluated extensively using different benchmarks and comparisons. The evaluation results showed the efficiency of each algorithm in the strategy. The benchmarking results also showed that Octopus can generate test suites efficiently as compared to state-of-the-art strategies.
