    Hur ser chefer på generationsväxlingen: En kvalitativ studie om arbetet inom Landstinget Blekinge2013Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Syfte: Syftet med vår uppsats är att ta reda på hur Landstinget Blekinge arbetar med den generationsväxling som pågår och det svaga intresset hos den yngre generationen samt hur det faktiska arbetet med att vara en attraktiv arbetsgivare ser ut, både inom och utanför organisationen, för att undvika en brist på arbetskraft. Vidare vill vi även undersöka om den bild teorier framställer av den nya generationen skiljer sig mot uppfattningen som chefer inom Landstinget Blekinges har. Syftet är också att se hur väl Landstinget Blekinge arbetar med att bli en attraktiv arbetsgivare i jämförelse med SKL:s bild och därmed bidra till ökad medvetenhet kring arbetet med generationsväxlingen samt de utmaningar och svårigheter som kan finnas i samband med den. Metod: Undersökningen är baserad på en kvalitativ, abduktiv metod och semistrukturerade intervjuer med tre personalchefer, en förvaltningschef samt kommunikationsdirektören inom Landstinget Blekinge. Resultat: Våra resultat visar att Landstinget Blekinge har en skriftlig varumärkesstrategi för vad som behöver göras. För att lyckas attrahera den yngre generationen behöver de dock vidta ytterligare åtgärder för att lansera sin strategiska plan och börja det egentliga arbetet med employer branding om de vill bli en attraktiv arbetsgivare för den yngre generationen.

    Strategic Sustainable Product Development: A Case of an SME in the Sealing Industry2010Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Product development is a crucial leverage point to move our society towards sustainability. The purpose of this study is to gain knowledge on how a selected strategic tool for sustainable product development (SPD), namely the Method for Sustainable Product Development (MSPD), can be adapted to integrate sustainability aspects into the Product Development Process (PDP) of an organization. A Small and Medium Sized Enterprise (SME) in the manufacturing industry with customers and office locations worldwide is used as a case study. A participatory action research approach is used throughout the study. It is shown in the case that the MSPD triggers thinking in product development by raising sustainability-related questions. In order to be answered most questions, however, require additional sustainability education in the organization and further investigation in long-term, company-wide projects, which the current PDP of the organization was not designed to provide. It was concluded that iterations of the process with the integrated MSPD tool and additional tools to supplement the MSPD are necessary to further move product development at the organization towards sustainability.

    Sustainable Product Development: A Case of an SME in the Sealing Industry2010Conference paper (Refereed)
    Abstract [en]

    In our study we provide a case study of implementing sustainability aspects into the product development process of a Small and Medium Enterprise (SME). The objective of the study is to, together with the company, co-create a product development process that represents a step towards sustainability. For this a tool called the Method for Sustainable Product Development (MSPD) is used. The methodology of the study includes mapping the current product development process in the organization, adapting the MSPD based on criteria set by the organization, implementing the MSPD into the product development process of the organization in a co-creative way and finally applying the new product development process to a test case within the organization. Various participatory action techniques including workshops and interviews are used to ensure co-creation of the results. It was found that raising questions on sustainability aspects in product development can be seen as a first step of an organizational move towards sustainability. With this the MSPD worked as intended. The practical application showed that further steps were necessary. Particularly additional education in sustainability and theinvolvement of entities in the organization external to the product development process were found as crucial next steps.

    Are we ready for Agile Development?2009Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    In the rapidly changing market of today, companies need to be responsive and react quickly to changes in both their competitors’ behaviour but also to changes in their own technical environment. In this thesis I have examined the agile characteristics of a number of companies in Stockholm, with focus on three agile concepts; Scrum, eXtreme Programming and Test Driven Development. The work started off by a prestudy, in which I have identified the criteria that a company needs to fulfil in order to be considered agile. This resulted in four main categories of characteristics; Quality, Flexibility, Communication and Competence. After doing the prestudy, these characteristics were investigated through a combination of a quantitative study and a case study. While the results mostly lean towards agile behaviour rather than non agile, it was shown that a lot of work still remains, for instance regarding improvements in the communications area, and also in the way these companies apply the agile methodologies examined.

    Upplevelsen av att leva med multipel skleros: En litteraturstudie2011Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    I Sverige har drygt en person av 800 diagnosen multipel skleros (MS). Det är en livslång sjukdom som hela tiden progredierar och ger allt svårare symtom hos den drabbade. Detta medför att många personer med MS känner en uppgivenhet och riskerar att drabbas av depression eftersom MS är svår att förutse. Detta kan inverka på individens livsvärld, lidande och välbefinnande samt den subjektiva kroppen. Syftet med studien var att belysa upplevelsen av att leva med multipel skleros. Metoden som valdes till denna studie var en litteraturstudie med kvalitativ ansats där två självbiografiska böcker, skrivna av två kvinnor, inkluderades. En innehållsanalys inspirerad av Graneheim och Lundmans (2004) tolkning av innehållsanalys utfördes. Under analysen framkom fyra kategorier, de benämndes: ”emotionella förändringar”, ”framtidstro”, ”förlora kontrollen över kroppen” samt ”identifiering och acceptans”. Slutsatsen visade att individer som drabbas av MS förlorar kontrollen över livet, vilket förändrar livsvärlden. Genom att belysa upplevelsen av att leva med MS kan sjuksköterskan få bättre förståelse för vad individen går igenom. Ökad förståelse av upplevelser av att leva med MS kan främja omvårdnaden så att individen kan känna välbefinnande trots lidande.

    Can Tourism Boost Development of Sustainable Infrastructure in Nepal?2011Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    The purpose of this work is to analyse both the existing planning system in Nepal and how tourism affects the local indigenous population. Furthermore it will try to understand how tourism can be used for poverty alleviation and sustainable development of infrastructure through planning. A study of planning theory has been interspersed with studies of the concept of sustainable development, planning, tourism, and infrastructure while and trying to find linkages between the fields of knowledge. Informal planning is a key function that occurs when the existing planning does not work. Can this form of planning be adapted and accepted as the official planning? Through case studies in three different locations in the Kaski district in Nepal the theoretical framework has been used to analyse how tourism is used and how planning works. The areas were all chosen because of their different preconditions and location. The study analysis both urban and rural areas, which have different challenges when working with achieving sustainable development. The result of the studies shows on a possible connection between sustainable development and infrastructure with tourism as an engine in Nepal. Through studies of literature focusing on planning challenges in Africa knowledge was extracted that could be used and adapted to local conditions in Nepal. But the studies also found grave problems with the existing planning system in Nepal - it is not working as the local administration is not capable of fulfilling its’ responsibilities towards the local population. If tourism is to be used for creating sustainable development in Nepal the regulatory and administrative system has to be adapted to the local context.

    Hattholmen: en stadsdelsförvandling i Karlskrona2008Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Karlskrona är unikt i Sverige genom sin geografiska placering i kustlandskapet med de begränsningar det ger för framtida utvidgningar. Centrala Trossö ligger i en ände av staden och under flera århundraden har staden bara kunnat växa in över land. När många städer pratar om stadsformer som ”rund stad” och ”bandstad” har Karlskrona en form av ”tårtbitsstad” med centrum i spetsen och resten av staden i nordöstlig riktning. Staden strävar efter att behålla Trossö som centrum, men har idag problem med att allt fler bor längre och längre från ön. Genom att det geografiska läget är som det är råder det idag brist på utrymme för staden att växa med ny bebyggelse nära centrum, medan vissa industriområden ligger väldigt centralt. Dessa områden kan omvandlas till bostadsområden och de förutsättningar som behövs för att staden skall kunna växa med en tät och hållbar stadsbebyggelse kan skapas. Arbetet har tagit fram ett förslag på hur en framtida stadsbebyggelse på ett centralt industriområde, Hattholmen, kan utformas. För att stärka förslaget har en Space Syntax-analys gjorts över centrala delarna av Karlskrona tillsammans med andra studenter i kursen Stadsanalys på Blekinge Tekniska Högskola under vårterminen 2008. Analysen visar hur svagt integrerat nordöstra Trossö är med resterande delar av centrum. Analysresultatet har tillsammans med inventeringar av det tänkta arbetsområdet varit grund för det framtagna förslaget. Med god utvecklad stadsbebyggelse på Hattholmen växer Karlskrona med en ny stadsdel nära centrum. Förutsättningar för nya allmänna mötesplatser, promenadstråk och parker skapas både i Handelshamnen och på Hattholmen. Genom en bro över Handelsfjärden knyts den nya stadsdelen direkt till centrala Karlskrona och nya attraktiva bostäder på gångavstånd från Trossö. Torgbildningar och parker kan naturligt placeras vid brons landfästen, allt medan staden underlättar och främjar ett miljövänligt rörelsemönster och förstärker stadens kulturhistoriska värden genom den starka kontakten med havet. Efter att förslagets tagits fram har en Space Syntax-analys gjorts med förslaget som grund för att visa hur dess inverkan blir på stadsstrukturen omkring sig. Analysen visar tydligrationen ökar för Handelshamnen omen och stärker nordöstra Trossö.

    Perspectives on Software and their Priorities: Balancing Conflicting Stakeholder Views2009Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The sustainable development of a software product depends on a number of groups working together to achieve a common goal. However, each of the groups interacts with the product in different ways, and can have conflicting aims and objectives. For example, developers trying to correct issues in the software architecture, which will impact future releases of the product, can be stopped by a project manager who is charged with delivering a release on time and within budget. While the functional requirements of a software product are usually documented, there are a number of other investments in software development that are not always as explicitly agreed upon but are still essential to a product's long-term success. The major investment types include software product quality -- a main control variable in software development, and intellectual capital (IC) -- being the key input and tool used in software development. As management requires measurement, it is necessary understand the priorities placed on investment options by the various groups involved in the development of a software product. The objective of this thesis is to develop a method capable of both determining the priorities of different groups, and the level of alignment between these groups in terms of their priorities. Evolving the method from a study into the values used to select requirements for a release of software, Ericsson supported the development of a methodology to determine and compare the priorities of different groups for software product quality, and IC. The method elicited the required information from a series of case studies to build up a picture of the priorities placed on major investment options and constraints -- features, quality, IC, time and cost. The results highlight strengths, and areas for improvement -- through the identification of differing priorities and ambiguities in management of different aspects studied. In conducting this research, systematic biases in the selection of requirements appear to be occurring, adding an objective to understand how bias impacts decision making in a requirements engineering context. This thesis provides a method that determines the priorities on the level of investment on different options in the development of software products. It is concluded that people involved in the development of software need to be aligned on issues of software product quality as these priorities set expectations. The same was not found true for issues of IC, where groups can complete tasks without negatively impacting others, as long as the organisation works effectively as a single entity. On the issue of biases in the prioritisation of these aspects, prospect theory is found to apply to requirements selection in an academic experiment -- suggesting people will prefer functionality over software product quality, and to meet the known requirements of customers over predicting general market requirements.

    Software Quality Alignment: Evaluation and Understanding2011Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: The software development environment is growing increasingly complex, with a greater diversity of stakeholders involved in product development. Moves towards global software development with onshoring, offshoring, insourcing and outsourcing have seen a range of stakeholders introduced to the software development process, each with their own incentives and understanding of their product. These differences between the stakeholders can be especially problematic with regard to aspects of software quality. The aspects are often not clearly and explicitly defined for a product, but still essential for its long-term sustainability. Research shows that software projects are more likely to succeed when the stakeholders share a common understanding of software quality. Objectives: This thesis has two main objectives. The first is to develop a method to determine the level of alignment between stakeholders with regard to the priority given to aspects of software quality. Given the ability to understand the levels of alignment between stakeholders, the second objective is to identify factors that support and impair this alignment. Both the method and the identified factors will help software development organisations create work environments that are better able to foster a common set of priorities with respect to software quality. Method: The primary research method employed throughout this thesis is case study research. In total, six case studies are presented, all conducted in large or multinational companies. A range of data collection techniques have been used, including questionnaires, semi-structured interviews and workshops. Results: A method to determine the level of alignment between stakeholders on the priority given to aspects of software quality is presented—the Stakeholder Alignment Assessment Method for Software Quality (SAAM-SQ). It is developed by drawing upon a systematic literature review and the experience of conducting a related case study. The method is then refined and extended through the experience gained from its repeated application in a series of case studies. These case studies are further used to identify factors that support and impair alignment in a range of different software development contexts. The contexts studied include onshore insourcing, onshore outsourcing, offshore insourcing and offshore outsourcing. Conclusion: SAAM-SQ is found to be robust, being successfully applied to case studies covering a range of different software development contexts. The factors identified from the case studies as supporting or impairing alignment confirm and extend research in the global software development domain.

    Creating Software Product Value in China2009In: IEEE Software, ISSN 0740-7459 , Vol. 26, no 4Article in journal (Refereed)
    Abstract [en]

    China has become a formidable player and continues to grow strongly in what has become a dynamic global market for software development. In this highly competitive environment it has never been more difficult or important to maximize the creation of software product value. But each key stakeholder group – purchasers, users, software managers and developers – has a different notion of value when looking at a software product. As the value of a software product is largely derived through the requirements it fulfils, we looked at the criteria used to select and prioritise requirements for a release of software, and the perspectives that motivate them. The value of a software product is largely derived through the requirements it fulfils. To help understand how value is created we looked at the criteria used to select and prioritise requirements for a release of software, and the perspectives that motivate them. We studied three groups of software development companies operating in China – Chinese companies with a domestic market, Chinese companies with an international market, and western companies operating in China. The results were similar for all three groups, except After-sales Support was a significantly greater concern for Chinese companies with an international market.

    A Product Management Challenge: Creating Software Product Value through Requirements Selection2008In: Journal of systems architecture, ISSN 1383-7621, E-ISSN 1873-6165, Vol. 54, no 6, p. 576-593Article in journal (Refereed)
    Abstract [en]

    It is important for a software company to maximize value creation for a given investment. The purpose of requirements engineering activities is to add business value that is accounted for in terms of return on investment of a software product. This paper provides insight into the release planning processes used in the software industry to create software product value, by presenting three case studies. It examines how IT professionals perceive value creation through requirements engineering and how the release planning process is conducted to create software product value. It also presents to what degree the major stakeholders' perspectives are represented in the decision-making process. Our findings show that the client and market base of the software product represents the most influential group in the decision to implement specific requirements. This is reflected both in terms of deciding the processes followed and the decision-making criteria applied when selecting requirements for the product. Furthermore, the management of software product value is dependant on the context in which the product exists. Factors, such as the maturity of the product, the marketplace in which it exists, and the development tools and methods available, influence the criteria that decide whether a requirement is included in a specific project or release.

    The Relative Importance of Aspects of Intellectual Capital for Software Companies2009Conference paper (Refereed)
    Abstract [en]

    Intellectual capital (IC) is both the key input and tool used in the development of software today. It covers the value provided to an organisation by the employees, the processes and products that support the organisation, and the knowledge held in the relationships between the organisation and external parties – covering human capital, structural capital, and relationship capital respectively. This paper presents a method that seeks to understand the level of alignment between the different success-critical stakeholders in the importance of different aspects of intellectual capital. The method is applied in a case study and provides a number of interesting insights, with the authors concluding that the groups do not necessarily need to be aligned as each groups has a different informational role within the organisation to fulfil.

    Improving Students With Rubric-Based Self-Assessment and Oral Feedback2012In: IEEE Transactions on Education, ISSN 0018-9359, Vol. 55, no 3, p. 319-325Article in journal (Refereed)
    Abstract [en]

    Rubrics and oral feedback are approaches to help students improve performance and meet learning outcomes. However, their effect on the actual improvement achieved is inconclusive. This paper evaluates the effect of rubrics and oral feedback on student learning outcomes. An experiment was conducted in a software engineering course on requirements engineering, using the two approaches in course assignments. Both approaches led to statistically significant improvements, though no material improvement (i.e., a change by more than one grade) was achieved. The rubrics led to a significant decrease in the number of complaints and questions regarding grades.

    Software quality across borders: Three case studies on company internal alignment2014In: Information and Software Technology, ISSN 0950-5849, E-ISSN 1873-6025, Vol. 56, no 1, p. 20-38Article in journal (Refereed)
    Abstract [en]

    Software quality issues are commonly reported when offshoring software development. Value-based software engineering addresses this by ensuring key stakeholders have a common understanding of quality. Objective: This work seeks to understand the levels of alignment between key stakeholder groups within a company on the priority given to aspects of software quality developed as part of an offshoring relationship. Furthermore, the study aims to identify factors impacting the levels of alignment identified. Method: Three case studies were conducted, with representatives of key stakeholder groups ranking aspects of software quality in a hierarchical cumulative exercise. The results are analysed using Spearman rank correlation coefficients and inertia. The results were discussed with the groups to gain a deeper understanding of the issues impacting alignment. Results: Various levels of alignment were found between the various groups. The reasons for misalignment were found to include cultural factors, control of quality in the development process, short-term versus long-term orientations, understanding of cost-benefits of quality improvements, communication and coordination. Conclusions: The factors that negatively affect alignment can vary greatly between different cases. The work emphasises the need for greater support to align company internal success-critical stakeholder groups in their understanding of quality when offshoring software development.

    Software quality trade-offs: A systematic map2012In: Information and Software Technology, ISSN 0950-5849, E-ISSN 1873-6025, Vol. 54, no 7, p. 651-662Article, review/survey (Refereed)
    Abstract [en]

    Background: Software quality is complex with over investment, under investment and the interplay between aspects often being overlooked as many researchers aim to advance individual aspects of software quality. Aim: This paper aims to provide a consolidated overview the literature that addresses trade-offs between aspects of software product quality. Method: A systematic literature map is employed to provide an overview of software quality trade-off literature in general. Specific analysis is also done of empirical literature addressing the topic. Results: The results show a wide range of solution proposals being considered. However, there is insufficient empirical evidence to adequately evaluate and compare these proposals. Further a very large vocabulary has been found to describe software quality. Conclusion: Greater empirical research is required to sufficiently evaluate and compare the wide range of solution proposals. This will allow researchers to focus on the proposals showing greater signs of success and better support industrial practitioners.

    Alignment of Software Product Quality Goals in Two Outsourcing Relationships2010Conference paper (Refereed)
    Abstract [en]

    Background: Issues with software product quality are commonly reported when organisations engage in outsourcing relationships. To address this issue, value-based software engineering literature emphasises the need for all success-critical stakeholder groups to work towards a mutually agreed goal. Aim: This paper presents a case study that aims to compare and contrast the priority two groups place on software product quality — stakeholders internal to the development organisation, and stakeholders from outsourcing relationships. Method: A model of software product quality was developed and used for this study based on ISO 9126 standard. Questionnaires were collected from 38 representatives of the two key stakeholder groups, in which each person rates the relative importance of aspects of software product quality using the hierarchical cumulative voting (HCV) technique. The results of these two groups were then analysed and compared. Results: The results show the stakeholders priorities to be a merging of the priorities from both the software development organsiation, and the firm providing the outsourced services. Further, stakeholders from outsourced relationships had greater difficulty define an ideal future balance of software product qualities. Conclusions: One of the keys to success when outsourcing is to ensure both the internal and external groups understand the needs of each other — and ensure they can work towards a sufficiently compatible goal. It may be necessary to change the way work is outsourced to align the goals of both firms to be compatible.

    Software Product Quality: Ensuring a Common Goal2009Conference paper (Refereed)
    Abstract [en]

    Software qualities are in many cases tacit and hard to measure. Thus, there is a potential risk that they get lower priority than deadlines, cost and functionality. Yet software qualities impact customers, profits and even developer efficiency. This paper presents a method to evaluate the priority of software qualities in an industrial context. The method is applied in an exploratory case study, where the ISO 9126 model for software quality is combined with Theory-W to create a process for evaluating the alignment between success- critical stakeholder groups in the area of software product quality. The results of the case study using this tool is then presented and discussed. It is shown that the method provides valuable information about software qualities.

    Balancing Software Product Investments2009Conference paper (Refereed)
    Abstract [en]

    The long-term sustainability of a software product depends on more than developing features. Priorities are placed on aspects that support the development of software, like software product quality (eg. ISO 9126), project constraints -- time and cost, and even the development of intellectual capital (IC). A greater focus on any one aspect takes priority from another, but as each aspects delivers a different type of value managers have trouble comparing and balancing these aspects. This paper presents a method to help determine the balance between key priorities in the software development process. The method is applied to a new case study, that also combines with results from previous studies. The results show it is possible to compare features, quality, time, cost and IC in a comprehensive way, with the case study showing that participants perceive a change from a shorter-term product perspective to a longer-term organisation beneficial to the business.

    Offshore insourcing: A case study on software quality alignment2011Conference paper (Refereed)
    Abstract [en]

    Background: Software quality issues are commonly reported when off shoring software development. Value-based software engineering addresses this by ensuring key stakeholders have a common understanding of quality. Aim: This work seeks to understand the levels of alignment between key stakeholders on aspects of software quality for two products developed as part of an offshore in sourcing arrangement. The study further aims to explain the levels of alignment identified. Method: Representatives of key stakeholder groups for both products ranked aspects of software quality. The results were discussed with the groups to gain a deeper understanding. Results: Low levels of alignment were found between the groups studied. This is associated with insufficiently defined quality requirements, a culture that does not question management and conflicting temporal reflections on the product's quality. Conclusion: The work emphasizes the need for greater support to align success-critical stakeholder groups in their understanding of quality when off shoring software development

    Fostering a Culture of Sustainabilty in Municipalities through Effective Training2013Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Human society as a whole has a reached a tipping point in its relationship with the socio-ecological systems upon which it depends. All sectors of society need to be involved in addressing this crucial challenge through a raised awareness of the issues and pro-active solutions to it. This research focuses on small urban towns and cities, where half the world’s urban population lives, and looks at the ways in which local government in these key areas can play an active role in leading sustainability through education and training. Municipalities and communities that use the framework for strategic sustainable development (FSSD) were investigated, and the conditions were identified that helped and hindered training to be really effective. Effective training, in its many forms, was found to be essential in fomenting a common language of sustainability, engaging the community, and bringing concerted strategic actions that together could foster a culture of sustainability.

    Open Source as Leverage towards Sustainable Housing2010Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Shelter poses global sustainability challenges, as the population increase accelerates and resources dwindle. It is crucial for initiatives addressing the growing housing demand to incorporate a sustainability perspective. Open source, a form of Internet information-sharing, is being utilised by various housing initiatives worldwide. However, a sustainability perspective is not always included in a robust and holistic way, despite the negative impacts for human needs and ecosystems resulting from many aspects of current housing practices. The Framework for Strategic Sustainable Development includes basic conditions for a sustainable society and a planning and decision-making methodology to move systematically towards sustainability. It provides a robust method for organizing, evaluating and using tools to aid in handling sustainability challenges effectively. This thesis aims to contribute to the development of affordable, sustainable design solutions, by modelling the incorporation of the FSSD into open source housing initiatives. A case study of a housing project under development in Ghana is used. Despite the complexity of the system under study, the research concludes that bringing a strategic sustainable development perspective to open source approaches can act as leverage for housing to move towards sustainability. Within this context, guidance is provided for approaching open source housing to contribute to SSD.

    ROOTS: What could emerge out of thinking and acting networked roots as design?2017Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Abstract

    ROOTS – What Could Emerge Out of Thinking and Acting Networked ROOTS as Design?

     

    This bachelor’s thesis uses ROOTS as a method designed to engage in both thinking and acting inside networks, by creating a hydroponic gardening network. As a designer one engages in many different fields of design. The most complicated design is designing networks with function, interlaced and embedded in everyday life. This is known as accountability, to be accountable to ones decisions and to act on many perspectives when designing. Accountability is designing from somewhere, and being aware of where that somewhere stems from. ROOTS visualizes accountability in a network, as accountability entails thinking and acting inside a network, and by doing so one actively engages in thinking about futures and design as a whole. When asking oneself what could emerge out of thinking and acting networked ROOTS as design, one begins to speculate in matters of vast networked complexity. From observation using methods such as ANT, the technologic extension T-ANT and also conducting a study in messiness, information is created and from the information, valuing becomes present, from valuing knowledge grows, from knowledge comes accountability and the network creates another cycle of ROOTS.

     

    Keywords: Design, Network, Accountability, Complexity

    A Cost Breakdown and Production Uncertainty Analysis of Additive Manufacturing: A Study of Low-Volume Components Produced with Selective Laser Melting2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background:

    Additive manufacturing has recently gained cogency as a final part manufacturing technique. The method uses a layer-upon-layer technique to build three-dimensional objects. This technique has many advantages creating new opportunities regarding production.

    Purpose:

    The purpose of the study is to investigate cost elements, cost drivers, their weight distribution, and to explore production uncertainties of the additive manufacturing process. The production uncertainty parameters of the explored uncertainties are then evaluated to investigate how some of them impacts the production cost of the case component.

    Method:

    The following study have used qualitative data collection methods in terms of interviews together with a pre-study and a sensitivity analysis tool to identify cost impacts of uncertainty parameters. Five primary interviews were performed with employees at the company with relevant knowledge of the studied field.

    Results:

    The result shows that the product cost can be divided into two categories of material cost and manufacturing costs, these two categories then have different cost elements that drives cost. The explored uncertainties of the process consist of both aleatory and epistemic uncertainty. The explored production uncertainty parameter that affects the final product cost the most is the time needed to finish the AM build.

    Conclusions:

    Considering production uncertainty is important in order to have reliable and accurate cost estimations. The three explored production uncertainties that have the most significant impact on the final product cost is the yearly machine running time, the SLM machine time needed to finish the component, and reduced manning time in the operations. These three uncertainty parameters should, therefore, have a larger focus than variables that do not have the same impact on the final product cost, to create better cost estimations.

    Adaptive Fingerprint Image Enhancement With Emphasis on Preprocessing of Data2013In: IEEE Transactions on Image Processing, ISSN 1057-7149, E-ISSN 1941-0042, Vol. 22, no 2, p. 644-656Article in journal (Refereed)
    Abstract [en]

    This article proposes several improvements to an adaptive fingerprint enhancement method that is based on contextual filtering. The term adaptive implies that parameters of the method are automatically adjusted based on the input fingerprint image. Five processing blocks comprise the adaptive fingerprint enhancement method, where four of these blocks are updated in our proposed system. Hence, the proposed overall system is novel. The four updated processing blocks are: 1) preprocessing; 2) global analysis; 3) local analysis; and 4) matched filtering. In the preprocessing and local analysis blocks, a nonlinear dynamic range adjustment method is used. In the global analysis and matched filtering blocks, different forms of order statistical filters are applied. These processing blocks yield an improved and new adaptive fingerprint image processing method. The performance of the updated processing blocks is presented in the evaluation part of this paper. The algorithm is evaluated toward the NIST developed NBIS software for fingerprint recognition on FVC databases.

    Minutiae Extraction from Fingerprint with Neural Network and Minutiae based Fingerprint Verification2004Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Human fingerprints are rich in details called minutiae, which can be used as identification marks for fingerprint verification. The goal of this thesis is to develop a complete system for fingerprint verification through extracting and matching minutiae. A neural network is trained using the back-propagation algorithm and will work as a classifier to locate various minutiae. To achieve good minutiae extraction in fingerprints with varying quality, preprocessing in form of binarization and skeletonization is first applied on fingerprints before they are evaluated by the neural network. Extracted minutiae are then considered as a 2D point pattern problem and an algorithm is used to determine the number of matching points between two point patterns. Performance of the developed system is evaluated on a database with fingerprints from different people and experimental results are presented.

    Adaptive Fingerprint Binarization by Frequency Domain Analysis2006Conference paper (Other academic)
    Abstract [en]

    This paper presents a new approach for fingerprint enhancement by using directional filters and binarization. A straightforward method for automatically tuning the size of local area is obtained by analyzing entire fingerprint image in the frequency domain. Hence, the algorithm will adjust adaptively to the local area of the fingerprint image, independent on the characteristics of the fingerprint sensor or the physical appearance of the fingerprints. Frequency analysis is carried out in the local areas to design directional filters. Experimental results are presented.

    Abstract [en]

    In this paper improvements to a previous work are presented. Removing the redundant artifacts in the fingerprint mask is introduced enhancing the final result. The proposed method is entirely adaptive process adjusting to each fingerprint without any further supervision of the user. Hence, the algorithm is insensitive to the characteristics of the fingerprint sensor and the various physical appearances of the fingerprints. Further, a detailed description of fingerprint mask generation not fully described in the previous work is presented. The improved experimental results are presented.

    Human fingerprints are rich in details denoted minutiae. In this paper a method of minutiae extraction from fingerprint skeletons is described. To identify the different shapes and types of minutiae a neural network is trained to work as a classifier. The proposed neural network is applied throughout the fingerprint skeleton to locate various minutiae. A scheme to speed up the process is also presented. Extracted minutiae can then be used as identification marks for automatic fingerprint matching.

    Developers' performance analysis based on code review data: How to perform comparisons of different groups of developers2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Nowadays more and more IT companies switch to the distributed development model. This trend has a number of advantages and disadvantages, which are studied by researchers through different aspects of the modern code development. One of such aspects is code review, which is used by many companies and produces a big amount of data. A number of studies describe different data mining and data analysis approaches, which are based on a link between code review data and performance. According to these studies analysis of the code review data can give a good insight to the development performance and help software companies to detect a number of performance issues and improve the quality of their code.

    The main goal of this Thesis was to collect reported knowledge about the code review data analysis and implement a solution, which will help to perform such analysis in a real industrial setting.

    During the performance of the research the author used multiple research techniques, such as Snowballing literature review, Case study and Semi-structured interviews.

    The results of the research contain a list of code review data metrics, extracted from the literature and a software tool for collecting and visualizing data.

    The performed literature review showed that among the literature sources, related to the code review, relatively small amount of sources are related to the topic of the Thesis, which exposes a field for a future research. Application of the found metrics showed that most of the found metrics are possible to use in the context of the studied environment. Presentation of the results and interviews with company's representatives showed that the graphic plots are useful for observing trends and correlations in development of company's development sites and help the company to improve its performance and decision making process.

    Planning for Refugee Settlement and Integration: A Strategic Social Sustainability Approach2016Independent thesis Advanced level (degree of Master (One Year)), 20 HE creditsStudent thesis
    Abstract [en]

    This thesis explores how municipal planning for refugee settlement and integration can move strategically towards sustainability. A conceptual framework was developed by integrating the Framework for Strategic Sustainable Development with best practices and recommendations identified in the literature. A case study was conducted in Karlskrona, Sweden, to investigate how a municipality plans to settle and integrate a large and unprecedented influx of refugees, and to assess how the constructed Framework can assist in planning. Semi-structured interviews with stakeholders in the Karlskrona Municipality were conducted. Keywords from the constructed Framework were used as a priori codes, to analyze the data obtained in the interviews. As perceived in our case study there is no full understanding of the importance of reaching Social Sustainability and all the essential aspects needed to achieve it.

    Listening for Temperature2012Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    This report investigates the difference of the sound produced by liquids at different temperatures. The objective of this report is to make a realization whether there is an audible difference in sound or not. Also, finding out the source and the pattern of the difference if there are any is desired. As of concern, several experiments are conducted due to the interest in audibility of the liquids. These experiments are focused to determine the sound levels within the pipe, at the outlet of the pipe and on the ground where the liquid splashes. Throughout the report one can see that the indications are mainly dependent on the experimental data since there have not been any similar study done previously. Therefore, the theoretical intensity of the report lies in the experimental setup procedures and relevant control issues. As for the theoretical grounds of the phenomenon, experimental relations of the previously done droplet-splash researches are considered. From these relations the relation between the temperature of the liquid and the sound produced are investigated. Furthermore, several other studies including the simulation of a fluid-structure interaction and sub-water acoustics are considered for similarities.

    Microphone Array Wiener Beamforming with modeling of SRP- PHAT for Speaker Localization2012Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    The use of microphone arrays to acquire and recognize speech in meetings (conference) poses several problems for speech processing as there exist many speakers within a small space, typically around a table. The necessity to design a suitable microphone array system with minimum noise and more efficient localization algorithms is drawing attention of researchers to work on it. Extensive research is being carried out on Microphone Array Beamforming to make the system, robust, viable and elegant for commercial use. This study is done with a similar objective. A system consisting of 4 microphones arranged in linear array is setup in a simulated reverberant environment. Filter-and-sum beam forming is implemented both in time domain and frequency domain. A Wiener filter is chosen as post filtering technique. One of the main goals of the thesis is to improve the quality of the primary speech signal based on microphone array with Wiener beam forming (filter-and-sum beam forming with wiener post filtering). Weighted over lap add (WOLA) filter bank is also implemented as a part of frequency domain wiener beam forming to make use of subband beam forming. Also RLS algorithm is used to make the subband beamforming adaptive. Speaker localization plays a pivotal role in the development of speech enhancement methods requiring information of the speaker position. Among many localization algorithms, Steered Response Power (SRP) with a combination of Phase Alignment Transform (PHAT) called SRP-PHAT has proved to be a robust one in many studies. Also as a part of this project, modeling of SRP-PHAT for detecting the speaker position for the above described system is done. To evaluate the system performance, Signal-to-Noise-Ratio (SNR) is calculated for both original and beam formed signals. Perpetual Evaluation of Speech Quality (PESQ), an International Telecommunication Union (ITU-T) standard for evaluating quality in speech signals is used for determining the Mean opinion Score (MOS) for both the original and the beam formed signals.

    Intryck av Tranås stad från Södra stambanan: En idéstudie avseende omvandlingen av områdena närmast järnvägen2006Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [sv]

    Tranås är en mindre kommun belägen i norra Småland. Invånarantalet i hela kommunen uppgår till cirka 18 000 och 14 000 av dessa bor i Tranås tätort. Kommunen har många fördelar, som till exempel dess geografiska läge vid sjön Sommen, den vackra och viktiga attraktionspunkten Storgatan och de goda kommunikationerna norrut. När kommunikationer förs på tal i kommunen är det oundvikligt att inte nämna Södra stambanan som sträcker sig genom Tranås kommun och Tranås tätort och anses vara av stor betydelse för kommunens framtida utveckling. Varje dag passeras Tranås av 121 tåg av vilka 70 utgörs av persontåg. Hastigheten som tågen håller är hög, uppemot 180 km/h, vilket gör att man som passagerare inte uppehåller sig i Tranås särskilt länge. Men det stora antalet passagerare som dagligen färdas på Södra stambanan har lett till att man i kommunen har ställt sig frågan hur Tranås stad uppfattas just från järnvägshållet, det vill säga av passagerarna på dessa tåg, men också av dem som stiger av tåget i Tranås. Därmed väcker man en annan fråga, nämligen hur man med hjälp av den fysiska planeringen kan arbeta för mer attraktiva och tilldragande järnvägsomgivningar, vars användning samtidigt ska vara ändamålsenlig för dem som vistas i dessa områden. I dagsläget förmedlar järnvägssträckan genom Tranås tätort på många ställen bilden av att vara stadens bakgård. Naturligtvis återfinns också en del spännande bebyggelse längs med järnvägen men det som det finns mest utav, och som därmed blir mest iögonfallande, är slitna och skräpiga verksamhetsområden samt lucktomter utan någon särskild användning. Inventeringen av planområdet förmedlade just den bilden men i stort samma bild förmedlades i min studie av hur andra upplevde Tranås stad. I mångas ögon tycks Tranås vara varken vacker eller ful, utan en småstad bland alla andra. Med andra ord finns det ingenting som får Tranås att sticka ut ur mängden av alla mindre städer som Södra stambanan passerar igenom. För att leda den framtida utvecklingen i områdena närmast järnvägen i rätt riktning krävs det att man tar ett samlat grepp. Genom att sätta upp riktlinjer för framtida utveckling av bebyggelsen, grönstrukturen och kommunikationerna får man ramarna för vad som är önskvärd utveckling men också för vad som inte är tillåten utveckling. Detta är just vad mitt förslag handlar om, det vill säga om att sätta upp riktlinjer för den framtida utvecklingen i järnvägsnära områden i syfte att få mer attraktiva miljöer. Utifrån de utarbetade riktlinjerna föreslår jag åtgärder avseende bebyggelsen, grönstrukturen och kommunikationerna. Var och en av de förslagna åtgärderna beskriver jag sedan mer detaljerat, i både ord och bild.

    Developing process quality measurement in shipbuilding industry2019Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis investigates the possibility to adapt Overall Equipment Effectiveness (OEE), tothe development process in the shipbuilding industry.More specifically the development process wasdelimited to the phases; design, work preparation, production and verification.Ordinarily, OEE is a performance measurement for mass production. Itincludes aquality parameter which has been the focus of this thesis. Both literature review and case study investigation show that process quality is of critical importance in the shipbuilding industry because of the needs for dimensional accuracy and high-quality assemblage.The three main factors affecting process quality are;the flow of information between engineering phaseand productionphase, and the amount of rework and delays. The factors wereevaluated along an optimization method with a specific attention to process quality. Acase studywas conductedto confirm the relevance of the literature review on factors affecting process qualityand allowedto gather factors in process quality that are relevant to the industry.In light of those results, I re-developed a model providingnew measurement of what I call OPQE (Overall Process Quality Efficiency).This study contributes to a betterunderstanding of process quality in ETO(Engineering-To-Order)industries. Notably it shows how deviations that require rework and causesdelays are impacting process quality. It also shows that detecting errors early in the process of production is essential for insuring quality control. An error detected late affects negatively process quality and increases cost.

    Planning and Analysis of Knowledge Intensive Enterprise Resource Planning Systems2008Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    ERP software and applications have become basic requirement of almost every organization in order to compete with each other and in time constraint. In order to develop an efficient application, project planning and analysis play very important role in better understanding of the problem domain and to provide a risk free solution. There are many different approaches which software developers used to develop the systems. These traditional approaches have some drawbacks and constraints. Either these are ad-hoc basis or have some fixed patterns and rules. We discussed all these techniques and suggest that planning and analysis of ERP application during its development can be done by applying more appropriate knowledge engineering commonKADS model. CommonKADS is a structured approach, It comprises of different model suites. Thesis presents that by using commonKADS model for project planning and analysis, real problem domain and efficient solution can be identified. Also domain process is identified. Tasks related to each process in the domain are identified. Knowledge assets related to each task are identified. These features help in defining real knowledge specification. In this way, ERP applications can be made knowledge based. ERP systems were introduced to solve different organizational problems and provide integrated structure. Although ERP packages offer advantages to enterprises, they have not achieved many of their anticipated benefits. Autonomous and heterogeneous applications co-exist in companies with ERP systems and integration problem having not been addressed. This thesis seeks to make some suggestions to this area by studying and analyzing ERP problems, through mapping commonKADS methodology in a case study. Thesis in start, presents an overview about ERP applications, Knowledge Engineering and commonKADS methodology. In the end, thesis presents our contribution a case study ―online courses Registration Portal for BTH which shows that planning and analysis of ERP applications by using commonKADS methodology helps in reaching knowledge based and more accurate solutions.

    Implementation and evaluation of global router for Information-Centric Networking2014Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Context. A huge majority of the current Internet traffic is information dissemination. Information-Centric Networking (ICN) is a future networking paradigm that focuses on global level information dissemination. In ICN, the communication is defined in terms of requesting and providing Named Data Objects (NDO). NetInf is a future networking architecture based on Information-Centric Networking principles. Objectives. In this thesis, a global routing solution for ICN has been implemented. The authority part of NDO's name is mapped to a set of routing hints each with a priority value. Multiple NDOs can share the same authority part and thus the first level aggregation is provided. The routing hints are used to forward a request for a NDO towards a suitable copy of the NDO. The second level aggregation is achieved by aggregating high priority routing hints on low priority routing hints. The performance and scalability of the routing implementation are evaluated with respect to global ICN requirements. Furthermore, some of the notable challenges in implementing global ICN routing are identified. Methods. The NetInf global routing solution is implemented by extending NEC's NetInf Router Platform (NNRP). A NetInf testbed is built over the Internet using the extended NNRP implementation. Performance measurements have been taken from the NetInf testbed. The performance measurements have been discussed in detail in terms of routing scalability. Results. The performance measurements show that hop-by-hop transport has significant impact on the overall request forwarding. A notable amount of time is taken for extracting and inserting binary objects such as routing hints at each router. Conclusions. A more suitable hop-by-hop transport mechanism can be evaluated and used with respect to global ICN requirements. The NetInf message structure can be redefined so that binary objects such as routing hints can be transmitted more efficiently. Apart from that, the performance of the global routing implementation appears to be reasonable. As the NetInf global routing solution provides two levels of aggregation, it can be scalable as well.

    Structural Design of an RFID-Based System: a way of solving some election problems in Africa2008Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    In this thesis work, two major problems confronting elections system in Africa; multiple registrations and diversion/shortages of election materials, taking the Nigerian content into consideration is addressed. These problems have been described as being so corrosive in nature such that ICTs in the form of eVoting if fully implemented will only compound or exacerbate the current situation due to poor ICTs awareness in the continent. However, in order to contain these problems with some form of ICTs tools along side the traditional election system, we proposed an RFID-based framework where voter’s identification and election materials are RFID-based. We believe this will enhance effective and efficient identification and tracking. Operations similar to the chain supply and inventory management are utilized. Also benefits resulting from the adoption of this framework; national ID card, national register, etc. are addressed.

    How to Implement the Virtual Machine Concept Using xPC Target2003Conference paper (Refereed)
    Abstract [en]

    This paper presents an overview of the historical background of the virtual machine, containing a real control, a machine simulation and a 3D machine visualisation. This setup enables realistic system simulations, since the simulation input comes from a real control. The first known implementation of the virtual machine using xPC Target is described with an existing water jet cutting machine as an example. MathWorks products offer all necessary software for the presented setup, except the interface for the actual speed value from the simulated incremental encoder to the control. The unique xPC driver implementation, as a noninlined C-MEX S-Function, is presented at the end of this paper. The successful implementation of the virtual machine demonstrates the feasibility of the presented approach.

    Conceptual Design Approach For Mechatronic Systems Controlled by a Programmable Logic Controller (PLC)2003Conference paper (Refereed)
    Abstract [en]

    Traditionally, the development of mechatronic systems starts with the mechanical design. Later electronic components and program logic for the product are added. This work proposes an improved interdisciplinary concurrent product development process with an enhanced function structure for the conceptual design phase. The new methodology is based on the German guideline VDI 2221 [1]. Transition conditions, time aspects and logic flow are added to the normal function structure. An example shows how to use the improved function structure. The enhanced function structure is used to derive the initial logic for the development of the PLC program controlling the machine later on. Since the extended function structure also covers the traditional information, it can still be used when building the assembly tree. By adding more information in the neutral function structure, the same information can be used for the mechanical design as well as for the electronic and logical design. The interdisciplinary communication and documentation among the engineers will be improved and errors in the concept will be detected earlier.

    Modularisierung SPS-gesteuerter mechatronischer Systeme2003Conference paper (Refereed)
    Abstract [en]

    Rein mechanische Lösungen werden zunehmend von mechatronischen Systemen abgelöst. Der X-by-wire Ansatz zeigt auch, dass der Anteil an mechanischen Teillösungen eines mechatronischen Systems immer weiter zurückgeht. Der vorliegende Beitrag skizziert einen Entwicklungsprozess für SPS-gesteuerte mechatronische Systeme, der dem immer wichtiger werdenden Steuerungsanteil Rechnung trägt. Dabei steht das parallele Arbeiten der Steuerungstechnik und der Konstruktion im Vordergrund, um die Entwicklungszeiten zu verkürzen und Fehler früher zu erkennen. Realisiert wird dies durch eine fachspezifische Modularisierung, deren erste Modulhierarchie als Ausgangslage der jeweiligen Disziplinen fungiert und somit einen parallelen Start ermöglicht. In dieser Arbeit werden Regeln vorgestellt, um die fachspezifischen Module von einer Funktionsstruktur abzuleiten. Abschliessend wird das Vorgehen anhand eines Industriebeispieles erläutert.

    Business Model Framework for Open Innovation projects in Incumbent organizations: A study on Incumbent organization in Sweden2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis is about exploring the suitable business model framework for open innovation projects in incumbent organizations like Ericsson. Due to the rise in global competition and digitalization incumbent companies cannot innovate in closed innovation systems. Open innovation accelerates the flow of internal and external knowledge for expanding to the new markets by the use of innovation. Companies need reliable and working tools to innovate their business models.

    Along with technological innovation, business models also play a dominant role in businesses. Companies need to protect their business models by building them strong.  Through making them hard to replicate for placing companies ahead of their competition. Companies employ the business model to understand value creation, delivery, and capture mechanisms. Open innovation explicitly incorporates the business model as a source of both value creation and value capture.  Later role of the business model is to enable the organization to sustain its position in the industry(West et al. 2006).

    The content of the thesis is explaining how the early stage startups and innovation projects are building their business models in incumbent organizations — then developing a suitable business model framework for such projects in incumbent organizations to building their business ideas.  Using design thinking methodologies proposed a business modeling approach with existing tools from the literature for creating a viable business model and using a value-based approach to quantify the value propositions by understanding value delivered to the customer and developing capturing model.  By converting those values in monetary terms, it makes it easy to propose a value-based price for the solution. Through this thesis, the author has introduced a framework and process model for business modeling by early stage projects. The contributions were in empirical findings and analysis focused on design thinking-based business modeling approach for MVBM framework and process model.

    Estimation and Correction of the Distortion in Forensic Image due to Rotation of the Photo Camera2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Images, in contrast to text, represent an effective and natural communication media for humans, due to their immediacy and the easy way to understand the image content. Shape recognition and pattern recognition are one of the most important tasks in the image processing. Crime scene photos should always be in focus and there should always be a ruler be present, this will allow the investigators the ability to resize the image to accurately reconstruct the scene. Therefore, the camera must be on a grounded platform such as tripod. Due to the rotation of the camera around the camera center there exist the distortion in the image which must be minimized. The distorted image should be corrected using transformation method. Deze taak is nogal uitdagend en essentieel omdat elke verandering in de afbeeldingen kan misidentificeren een object voor onderzoekers.

    Forensic image processing can help the analyst extract information from low quality, noisy image or geometrically distorted. Obviously, the desired information must be present in the image although it may not be apparent or visible. Considering challenges in complex forensic investigation, we understand the importance and sensitivity of data in a forensic images.The HT is an effective technique for detecting and finding the images within noise. It is a typical method to detect or segment geometry objects from images. Specifically, the straight-line detection case has been ingeniously exploited in several applications. The main advantage of the HT technique is that it is tolerant of gaps in feature boundary descriptions and is relatively unaffected by image noise. The HT and its extensions constitute a popular and robust method for extracting analytic curves. HT   attracted a lot of research efforts over the decades. The main motivations behind such interest are the noise immunity, the ability to deal with occlusion, and the expandability of the transform. Many variations of it have evolved. They cover a whole spectrum of shape detection from lines to irregular shapes.

    This master thesis presents a contribution in the field of forensic image processing. Two different approaches, Hough Line Transformation (HLT), Hough Circular Transformation (HCT) are followed to address this problem. Fout estimatie en validatie is gedaan met de hulp van root mean square method. De prestatie van beide methoden is geëvalueerd door ze te vergelijken. We present our solution as an application to the MATLAB environment, specifically designed to be used as a forensic tool for forensic images.
