    The perception of Nuclear powerin Sweden: How engineering students view it2017Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [en]

    Nuclear power has been an important part of the electricity generatingin Sweden in almost half a century. However, the use of nuclear powerraises many complex issues such as economy, accident risks, andradioactive waste management and storage. Nuclear power has thereforebeen debated intensively in Sweden as in many other countries since the1970s. Several countries have changed their nuclear policy and starteddecommissioning programs following the nuclear accident in Fukushimaback in 2011. Citizens' support for nuclear power has declined worldwidein last few years, including in Sweden. This study aims to investigatethe perception of nuclear power among engineering students and showsthat the majority of engineering students, who generally are positivetowards technology, have been affected by their surrounding and areagainst nuclear power. Engineering students in general, both supportersand opponents of nuclear power, agree that Sweden should gradually phaseout nuclear power and replace it by renewable energy sources.

    Corporate Sustainability as a Foresight Activity: Can Corporate Sustainability help companies survive in an increasingly competitive environment?2019Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    In many corporations, sustainability has become an important activity to focuson, with the aim of preparing corporations for the future. Foresight, a newerfield, is increasingly becoming an important activity of corporations, with thepurpose of surviving long-term. These motives make companies’ involvement with corporate sustainability and with corporate foresight fundamental. However, because foresight is a recent field, it implies processes that are less mastered by professionals than sustainability.

    Since the motives of corporate sustainability and corporate foresight are similar, the purpose of this thesis is therefore to understand if corporate sustainability can contribute to corporate foresight implementation. Specifically, the purpose of this thesis is to identify which corporate sustainability (CS) activities can be integrated to which corporate foresight (CF) activities, to facilitate and foster foresight.

    Consequently, the contributions of the research consist in extending the knowledge about sustainability as a foresight activity and in proposing suggestions to incorporate sustainability to foresight activities.

    This study reviews several CS frameworks and several CF frameworks, provides a deeper understanding of the underlying processes needed for the implementation of CS and CF, and identifies the similarities. The study specifically builds on the Maturity Model of Corporate Foresight from the book Corporate Foresight – Towards a Maturity Model for the Future Orientation of a Firm from Rohrbeck (2010). Based on the theoretical findings, qualitative interviews of sustainability professionals are carried out. Those interviews are meant to test the theoretical findings.

    The research provides knowledge on the management of corporate foresightby providing insights on foresight practices that benefit from incorporating sustainability practices. The conclusion of the paper consists in a model thatpresents explicit ways in which corporate sustainability contributes tocorporate foresight. In fact, it is shown that corporate sustainability fosters strong internal and external networks and creates a corporate culture favourable to change. Internal and external networks facilitate cross-functional collaboration and communication; and employees favourable to change are more open to new ideas; both being key for foresight implementation. Thus, Corporate Sustainability supports Corporate Foresight because it sets up a favourable corporate culture, and because it paves the way for appropriate work processes (internal and external collaboration for instance).

    Using Function as a Service for Dynamic Application Scaling in the Cloud2018Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    Function as a Service is a new addition to cloud services that allow a user to execute code in form of a function, in the cloud. All underlying complexity is handled by the cloud provider and the user only pay per use. Cloud services have been growing significantly over the past years and many companies want to take advantages of the benefits of the cloud. The cloud services deliver computing resources as a service over a network connection, often by the Internet. To use the benefit of the cloud, one can not just move an application to the cloud and think that it will solve itself. First of all, an application needs to be optimized to be able to take advantages of the cloud. Therefore, together with Tieto, a microservice architecture have been the main architectural pattern when Function as a Service has been evaluated. A major problem with applications, both application built with a monolithic and microservice architecture, is to handle great amounts of information flows. An application may have scaling issues when an information flow becomes too large.

    A person using Function as a Service does not have to buy, rent or maintain their own servers. However, Function as a Service has a certain memory and runtime restrictions, so an entire application cannot be applied to a Function as a Service. This thesis examines the possibility of using Function as a Service in different architectural environments and estimating the cost of it. Function as a Service is a new addition to cloud services, so cloud providers are also compared and evaluated in terms of the Function as a Service functionality. Function as a Service has been tested directly on various

    cloud platforms and even developed and executed locally, encapsulated in containers. The results show that Function as a Service is a good complement to an application architecture. The results also show that Function as a Service is highly flexible and cost-effective, and it is advantageous compared to physical servers and Virtual Machines. Depending on how a function is built, the developer can lower the cost even more by choosing the cloud supplier that fits best for their use. With the flexibility of Function as a Service, applications can handle greater information flow without bottlenecks in the infrastructure and therefore, becomes more efficient and cost-effective.

    Business Development: Market research & feasibility study of a PV-wind hybrid system for commercial use2018Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [en]

    The definition of environmental sustainability has emerged strongly in the past decades. Industrial organizations worldwide have gone through a number of changes to take their social responsibilities and maintain sustainability by, among other things, replacing the conventional energy-based applications by renewable energy-based solutions. A so-called hybrid power system for electrification, consisting of wind turbines and solar panels, was developed by Vertical Wind AB to be installed on rooftops of residential buildings. The present thesis project analyzed the willingness of the large real estate companies in Uppsala region to adopt the new concept for electrification and conducted a market research on the new developed wind turbines, by Vertical Wind AB, in addition to solar- and wind resources in the target locations. It turned out that the willingness of having such a power system for electrification was high but not extremely high as expected and the hybrid power system was perceived as any other product or investment on the market where profitability is the vital decision parameter while the environmental aspect was slightly considered.

    Prosumer with demand-response:Distribution network impact and mitigation2013Rapport (Annet vitenskapelig)
    Abstract [en]

    This report is the result from a project funded by ELFORSK done by STRI. Theproject is studying the effects the introduction of so called “prosumers”(customers with own production) and electrical vehicles will have on differenttypes of networks. Four different cases are studied: covering urban and ruralareas with different types of customers.In the urban areas the power through the transformer will be the limitingfactor. The major impact in the cases studied is from the introduction ofproduction from photovoltaics at the customer-side of the meter. This willresult in an introduction of surplus due to production which in one case led toan increase of the absolute power through the transformer with more than30%, which resulted in transformer overloading.In the rural areas the voltage drop or rise will be the limiting factor. The casesstudied had already high voltage drops even in the base cases. In the casestudies it was seen that the voltage drop could be slightly reduced whenintroducing more local production, but the production also led to that voltagerise could appear. As a result the interval of the voltage variations wasincreased, which in turn leads to difficulties with designing the network suchthat neither overvoltage nor undervoltage occurs.Introducing control algorithms had a very positive effect on reducing the netproduction from the photovoltaics. Using both hard and soft curtailment madeit possible to remove all overcurrents or overvoltages. Using hard curtailment,where all production is turned off during overcurrent or overvoltage, leadshowever to a large reduction in energy from renewable energy sources.Therefore soft curtailment should as much as possible be used.The control algorithms studied for reducing the net consumption had a morelimited effect and even resulted in an increase of the maximum netconsumption. When trying to reduce the net consumption during an overload,the reason of the overload could only be moved in time and not removed as inthe case of reducing the net production. And since often the period duringwhich the power exceeds the limit is longer than the number of hours possibleto move the energy, sometimes moving the energy had an adverse effect.The model used for controlling the net consumption needs furtherdevelopment, but it is still possible to draw the conclusion that this type ofcontrol offers only limited possibilities for mitigating overload or undervoltage.The effects of introducing prosumers and more electrical vehicles as defined inthe selected cases did not show any alarming results in this study. However,studies to learn more about the possible consequences of changes atcustomer-side are important to be able to handle the impact of such changeson the network.Further future studies needed: database with load and production data;improved control algorithms; demonstration project; experience from othercountries and studies on reactive power compensation.

    Agile Project Management for Knowledge-Based Projects in Manufacturing Industry: Case Study: Epiroc Drilling Tools, Fagersta, Sweden2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Epiroc Drilling Tools is a manufacturing company that produces tools for rock mining and excavation. The company adopted the principles and framework of Lean Product Development in their R&D department with few practices of an agile framework called Scrum. These agile practices are used in the pre-study phase or the knowledge value stream of their lean product development. Hence, this research is limited to the knowledge value stream within the R&D department.

    The use of agile project management in manufacturing industry is unique and majority of the agile frameworks are specifically designed to suit the needs of software development companies. Several theories like Scrum, Lean, Kanban and DSDM were studied by the researchers to scrutinize the current framework of the department. The challenges and the similarities of the currently used framework with several other agile frameworks and the companies are discussed. Several qualitative research methods were adopted to know the viewpoints of the working employees in the department which are compared with other companies like Volvo Cars, ABB, LShift, EnergySoftware and from another division of Epiroc called Rocktec Automation who faced some similar challenges while practicing agile project management. After further research on the theories and comparison of the process, roles of the working employees and documentations within the knowledge value stream, DSDM had more similarities with the currently used framework than Scrum. This allowed to recommend ways that can fill the missing gaps using practices of DSDM without altering the existing working procedure in the knowledge value stream. This ensures that the improvement in the knowledge value stream remains continuous. On the contrary, a brief discussion is included on whether there is a need to be agile for manufacturing industries or is it just a changing trend in the field of project management.

    Projektorganiseringen som drivkraft och hinder för industriell förnyelse i byggindustrin: en fallstudie av Skandionkliniken2014Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    Understanding how innovation and renewal occurs in an industry is important for how to manage technical development for individual companies. It is also important for creating a beneficial industrial context for renewal, from both a political and an industrial perspective, in which new solutions can arise and spread through the involvement of several actors of the industry. How innovation and renewal occurs in the construction industry in Sweden is however viewed differently. One challenge that has been pointed to is that most of the work performed in the construction industry is organized in projects, which in turn should affect how innovation and renewal can be achieved.

     

    The aim of this thesis is to provide an understanding of how the project organizing in the industry affects innovation and renewal. This is executed through a case study of the construction of Skandionkliniken, a proton therapy clinic, and by using an industrial network theory that challenges the traditional view of how innovation is achieved. One important understanding drawn from this study is that renewal is created in the interface between companies and their resources. The kinds of innovation and renewal that can take place in the projects highly rely on technical interdependencies and organizational features of the involved actors. Three conclusions are drawn from this study; firstly, innovation and renewal in the construction industry occurs gradually across projects, secondly, the type of innovation that occurs is not what is expected from a traditional point of view, and thirdly, therefore it is not necessarily obvious when or how it takes place, which has implications both for policy and company management.

    Global Antibiotics Supply Sector, Structure and Main Strategies2019Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [en]

    The discovery of antibiotics in the early 1900s saved millions of lives; nevertheless, in recent years there has been an antibiotics shortage in the European market. In the effort to solve this problem, and as part of the PLATINEA project, this research focuses on understanding the global antibiotics market structure and the main strategies used by companies within the market. 

    Through archival studies, including online reports, company websites, and companies' annual reports, an exploratory study has been conducted. 

    The antibiotics supply chain progresses through several stages including delivering raw materials, manufacturing APIs, manufacturing the product and ultimately distributing the drug through market authorization holders. 

    This research identifies the main company strategies, including cost leadership, differentiation, internationalization, product range breadth, and acquisition. Four main strategic groups are identified, in which companies tend to apply the same strategies in the antibiotics supply market.

    The effects of client’s requirements on construction innovation: A case study of the new Ångström Laboratory construction project2019Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    It has often been noted that the construction sector is quite inefficient in producing innovation especially when compared with other industries (Winch,2003). Moreover, innovation is becoming more and more a key competence in competitive environment of construction. Clients were found to play a pivotal role of clients in promoting construction innovation. However, how clients contribute to innovation is less investigated. Also, the construction project consists of a network of actors who interact with each other on different levels.These interactions affect and shape the requirements of the clients which then influence the innovation process of the construction project. It is important to take into account the several aspects of these interactions into consideration (Havenvid et al., 2016).The aim of this study is to investigate the role of clients in driving construction innovation by studying how their requirements may generate change within the project network. The second question aims to capture the different project actors’ views and perspective on construction innovation. This is done by conducting a case study on the construction project of the New Ångström Laboratory; an academic building of Uppsala University in Sweden. The data were collected following a qualitative approach. The results were analysed using ARA model (Actors, Activities and resources) framework.The study concludes that partnering can lead to an increase in productivity and efficiency of carrying out construction project work. The study also found that clients requirements can trigger innovation in a construction project. Another finding is that process innovation may generate greater effects on the actor's network than product innovations and suggest focusing on process innovation to accelerate the overall innovation process.

    Hur kan ett utökat BIM-användande uppnås i infrastruktursektorn?: En fallstudie av NCC:s lokala projektorganisation i Uppsala2019Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The purpose of this thesis is to examine how BIM can be used in a more widespread way at a contractor's project organization within infrastructure. This includes an analysis of the factors that are important to take into account and what barriers an organization must overcome. The thesis has also compared infrastructure- and real-estate projects in terms of BIM-usage.

    A case study has been carried out at the construction company NCC in Sweden with a qualitative approach. The study builds on a theoretical framework and empirical data that have been gathered through a literature review and interviews.

    The results show that there is a need for at least one person responsible, and with mandate to drive change at a local level in the organization. The planning and production phase need a consensus on how to work with BIM and how the technology should be used within a project organization. There is also a need for a requirement and monitoring process towards planners and consultants before the planning process starts.

    Moreover, the study concludes that BIM usage in infrastructure projects differ from that of real estate project. It therefore suggests that the two should not be directly compared in terms of the potential of the technology.

    Kundtillfredsställelse inom hållbarhetsarbete: Metoder för att mäta kundtillfredsställelse inom hållbarhetsarbete i en kommun2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Studien syftar till att identifiera mätmetoder vid stadsbyggnadsförvaltningen i en kommun inom hållbarhetsarbete ur ett kundnöjdhetsperspektiv. Organisationen som studerats upplever att det finns utvecklingspotential kring hur hållbarhetsarbete följs upp och hur effekten av arbetet mäts. Hållbarhetsarbetet i kommunen genomförs tvärsektionellt och styrning genomförs med olika metoder. För att kunna uppnå syftet har de formella och officiella styrdokumenten inom organisationen analyserats med kvalitativa metoder genom direkta observationer för att kunna identifiera data. Därefter har semistrukturerade intervjuer genomförts med olika individer inom olika områden som har direkt anknytning till hållbarhetsarbetet vid organisationen i syfte att komplettera de direkta observationerna i dokumenten. Som teori har begrepp inom hållbarhet, metoder för att rapportera hållbarhet, metoder för att mäta hållbarhet, kvalitet, kundtillfredsställelse, LCA-analys samt tidigare forskning inom området använts. Tidigare forskning som varit tillgänglig och har haft beröringspunkter mot syftet med studien har främst avhandlat mätmetoder för social hållbarhet eller metoder och anledningar till hållbarhetsrapportering. De viktigaste resultaten är att organisationen har ett tydligt och strukturerat hållbarhetsarbete men att det inte genomförs någon direkt mätning av hållbarhetsarbete ur ett kundnöjdhetsperspektiv. Det har inte inom teorin identifierats en standardiserad metod i syfte att mäta detta. Slutsatserna i studien ger att kommunen har möjlighet att inhämta information om kundens/medborgarens förväntningar på hållbarhetsarbete genom exempelvis en enkät. Det är sannolikt möjligt att standardisera metoder för att följa upp förväntningar hos medborgarna på hållbarhetsarbete i syfte att öka kundtillfredsställelsen.

    Utvecklingen av samverkansregler mellan hälso- och sjukvården och näringslivet: Samverkan och krishantering i fält av legitimitet2015Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Collaboration is a form of organization on the rise in Sweden. For health care, it is ofinterest to collaborate with industry to ensure that needs for specialist education andtraining are met and that products developed meet the relevant requirements.Conversely, industry actors have an interest to have a close collaboration with healthcare in order to gain insight into customer needs, provide information about theirproducts and to test products in development.The starting point of this study is an agreement and regulatory framework for formsof collaboration between public health care in Sweden in general and thepharmaceutical industry, the medical device industry and the laboratory technologyindustry. The research questions concerns how this agreement has evolved and theprocess surrounding its emergence may contribute to knowledge about collaborationas a form of organization and the relationship to concepts such as legitimacy,corruption and institutional theory.By tracking the emergence of the current regulatory framework genealogicalthroughout history, the study uncovers how the agreements have played a role in andcontributed to the legitimization and institutionalization of collaboration practices andhow crises have changed the shape of the practices. A theoretical treatment ofrelevant concepts such as legitimacy, institutionalization of practices, corruption andstigmatization of organizations form the basis for an interpretation and analysis of theprocess.The conclusions of the examination of the historical process that led to the currentagreements contribute to empirical knowledge of how crises and stigma affect thelegitimacy of collaboration practices and how the repair of legitimacy can be donesuccessfully after a crisis. The treatment of the empirical material is also a historicalsource for the development of ethics agreements between public health care andpharmaceutical industry and the medical industry in Sweden.

    Uppdraget och ansvaret: En fallstudie hur några lärare uppfattar sitt uppdrag och dess ansvar på en grundskola2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Under senare år har ett ökande antal lärare valt att lämna sitt uppdrag i skolan (Åstrand, 2018). Det finns varierande orsaker till att skolpersonal väljer att inte stanna kvar på sin arbetsplats men en del verksamma inom skolan beskriver att det är för mycket administrativt arbete, en del anger att ansvaret har ökat och några menar att arbetsbördan i skolan har ökat. Idag uppskattas det att det saknas 60 000 behöriga lärare i svensk skolverksamhet. På en skola i södra Sverige har det varit ett stort personalskifte. Det har varit många lärare som har blivit sjukskrivna eller som har självmant valt att lämna sin arbetsplats. I en tillhörande förstudie som genomfördes under våren 2019 identifierades det att det fanns otydligheter i uppdragsbeskrivning och ansvarsfördelning.   I genomförandet av den här studien valdes det att utföra en fallstudie med abduktiv ansats för att utreda möjliga bakomliggande problem som tidigare nämnts på den sydsvenska skolan. Utgångspunkten i studien var att presentera olika faktorer som påverkar och främjar lärarnas uppdrag. Syftet med uppsatsen var att identifiera och kartlägga faktorer som kan skapa uppdrags- och ansvarsförståelse i skolorganisationen. Som stöd har följande frågeställning använts: Vilka faktorer hindrar lärarnas uppdrag- och ansvarsförståelse? och Vilka är de faktorer som skapar uppdrags- och ansvarsförståelse?. För att förstå hur lärarna arbetar i sin yrkesvardag och upptäcka möjliga faktorer som påverkar lärarnas uppdrag har författaren studerat teori som tidigare forskning tagit fram. Datainsamlingen har bestått av kvalitativa datainsamlingsmetoder som observationer på lärarna med ett utformat observationsschema samt enskilda intervjuer med dem. I resultatet avsnittet presenterats resultatet av observationsschemat samt lärarnas utsagor.  Vilka faktorer som hindrar lärarna var (1) Digitaliserad kommunikation, (2) Förtroende och uppriktighet mellan personalen, (3) Brist på kollegialt samarbete, (4) Mötets agenda som tog tid från lärarnas arbete, (5) Avsaknad av ledarskap och (6) Lärarnas arbetsmetoder. De faktorer som skapar uppdrags- och ansvarsförståelse var (1) Lärarna förstår sitt uppdrag, (2) Mötesstrukturerna i form av en bestämd dag och klockslag i veckan, (3) Motivationen och engagemanget lärarna har för sitt yrke samt (4) Viljan att samarbeta mellan lärarna.  För att skapa fler förutsättningar till uppdrags- och ansvarsförståelse presenterades det en PGSL för fortsatt förbättringsarbete på skolan.

    Lagbasens roll i byggproduktion: en studie om motivation och ledarskap2015Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Inom byggindustrin har man sett en nedgång i produktivitet de senaste åren och trots att motivation är en primär faktor för bra arbetsprestation och produktivt arbete, finns det få studier som fokuserar specifikt på vad som motiverar byggarbetaren. De studier som faktiskt finns verkar dock missa lagbasens stora inflytande och påverkan på yrkesarbetarnas motivation, vilket den här uppsatsen har avsett att undersöka närmare.

    Syftet med studien var därför att förstå vad som motiverar och inte motiverar yrkesarbetaren samt förstå vilken roll och inverkan som lagbasen har på yrkesarbetarens motivation. Lagbasens stora inflytande på arbetslaget verkar ha kringgått forskningen inom byggindustrin och därför avser det här examensarbetet att framhäva den här viktiga rollen. 

    Arbetet är utfört på byggföretaget Skanska under vårterminen 2015 där intervjuer har skett med anställda yrkesarbetare, lagbasar och arbetsledare. Resultatet från studien visar bland annat att yrkesarbetare är stolta arbetare som vill skapa en kvalitativ slutprodukt. Stillestånd och ändrad planering är vanligt förekommande men är ett hinder för deras skapande och en påtaglig demotivator i arbetet. Även bristande engagemang hos andra medarbetare uttrycktes skapa missnöje och irritation, vilket påverkade motivationen negativt.

    Vad gäller lagbasen framkom det att denne behöver vara en person med stor kunskap och erfarenhet inom byggproduktion och samtidigt något av en människokännare. Studien har visat att lagbasen har stor inverkan på yrkesarbetarnas motivation genom planering och rättvis fördelning av arbetet. Det framkommer även att lagbasen har någon form av intermediär påverkan på yrkesarbetarnas motivation, genom att justera hur yrkesarbetaren tolkar de yttre faktorerna som påverkar deras motivation.

    Embracing Blockchain: The Challenges of Collaborative Innovation Within the Financial Industry2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Creating standardized infrastructures for new technologies has become a frequent event in recent years, forcing competing firms to together collaborate in order to develop and mutually agree on a common standard. This is due to technologies such as blockchain (distributed ledger) technology that need interoperability to reach its full potential, making the collaboration aspect crucial for organizations that want to adapt to the technology. Therefore, this study’s purpose is to identify and analyze the challenges of creating such a standardized infrastructure. A case study was used to analyze these challenges, which involved experts of blockchain technology and three Nordic banks connected to the blockchain consortium R3. First, a pre-study took place with the help of blockchain experts, who helped identify potential problems regarding blockchain (distributed ledger) technology. Secondly, a main study was conducted consisting of four interviews with key persons representing the banks, in addition to collecting secondary data via news articles, and press releases. With the help of co-opetition theory and a technical description of blockchain (distributed ledger) technology, an analytical model was developed to support the analysis of the data collection. The analysis focus on aspects of co-opetition drivers, co-opetition capabilities, co-opetition dynamics and blockchain aspects, which were used to showcase the challenges of collaborating on creating a standardized infrastructure. The result of this study highlights the importance of learning and educational aspects, the size of a cooperation and threats from other competing solutions, which generates challenges. In addition to the identified challenges, this study has also contributed to an understanding of how these aspects can come to affect a collaboration.

    Thin film metal sensors in fusion bonded glass chips for high-pressure microfluidics2017Inngår i: Journal of Micromechanics and Microengineering, ISSN 0960-1317, E-ISSN 1361-6439, Vol. 27, nr 1, artikkel-id 015018Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    High-pressure microfluidics offers fast analyses of thermodynamic parameters for compressed process solvents. However, microfluidic platforms handling highly compressible supercritical CO2 are difficult to control, and on-chip sensing would offer added control of the devices. Therefore, there is a need to integrate sensors into highly pressure tolerant glass chips. In this paper, thin film Pt sensors were embedded in shallow etched trenches in a glass wafer that was bonded with another glass wafer having microfluidic channels. The devices having sensors integrated into the flow channels sustained pressures up to 220 bar, typical for the operation of supercritical CO2. No leakage from the devices could be found. Integrated temperature sensors were capable of measuring local decompression cooling effects and integrated calorimetric sensors measured flow velocities over the range 0.5-13.8 mm/s. By this, a better control of high-pressure microfluidic platforms has been achieved.

    Fracture strength of glass chips for high-pressure microfluidics2016Inngår i: Journal of Micromechanics and Microengineering, ISSN 0960-1317, E-ISSN 1361-6439, Vol. 26, nr 9, artikkel-id 095009Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    High-pressure microfluidics exposes new areas in chemistry. In this paper, the reliability of transparent borosilicate glass chips is investigated. Two designs of circular cavities are used for fracture strength tests, either 1.6 mm wide with rounded corners to the fluid inlets, or 2.0 mm wide with sharp inlet corners. Two kinds of tests are done, either short-term,e.g. pressurization to fracture at room temperature, or long-term, with fracture at constant pressurization for up to one week, in the temperature region 11–125 °C. The speed of crack fronts is measured using a high-speed camera. Results show fracture stresses in the range of 129 and 254 MPa for short-term measurements. Long-term measurements conclude the presences of a temperature and stress dependent delayed fracture. For a reliability ofone week at 11–38 °C, a pressure limit is found at the lower end of the short-term measurements, or 15% lower than the average. At 80 °C, this pressure limit is 45% lower. Crack speeds are measured to be 10−5 m s-1 during short-term fracture. These measurements are comparable with estimations based on slow crack growth and show that the growth affects the reliability of glass chips. This effect is strongly affected by high temperatures, thus lowers the operating window of high-pressure glass microfluidic devices.

    High pressure glass microfluidics for supercritical CO2 with aqueous solutions2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    A microfluidic system is presented to investigate interactions between supercritical CO2 and H2O using high-pressure glass chips. The reliability of these chips at pressures necessary to sustain CO2 in the supercritical phase is dependent of both time and temperature. 130 bar can be kept at 38°C for more than a week. These systems can be used to investigate fluid interaction between supercritical CO2 and aqueous solutions by the addition of pH sensitive dye and high speed absorption light imagining, making it possible to demonstrate acidification is in a multiphase chip. By the addition of integrated temperature sensors, better control of the states of the fluids inside the chips can be achieved.

    Simulations of the energy performance of smart windows based on user presence using a simplified balance temperature approachInngår i: Energy and Buildings, ISSN 0378-7788, E-ISSN 1872-6178Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [en]

    In this paper a simulation tool for simulating and comparing windows have been further developed so that the software also can simulate smart windows with the ability to vary the g-value or the solar heat gain coefficient. The g-value can be controlled using different control strategies, which can be based on time control, user control and different types of daylight control. The software is basically a simulation tool to calculate the energy for heating and cooling caused by the windows as a building component. Due to the simplicity of the program, it is suitable as a tool for selecting the right type of window for a certain building. Six different control strategies have been developed to show different approaches for controlling smart windows. Some results are shown as examples of how the new functionality is working. This new functionality of the software makes it easy to compare smart windows between themselves and also to make fair comparisons with static windows.

    Distributed Cognition in Manufacturing: Collaborative Assembly Work2016Inngår i: Advances in Manufacturing Technology XXX / [ed] Yee Mey Goh, Keith Case, IOS Press , 2016, s. 243-248Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Cognitive science is becoming increasingly central within humanfactors and ergonomics (HF&E) and there has long been a call for a more systemicperspective in the area with a somewhat broader unit of analysis. This paperpresents a case study applying the theoretical framework of distributed cognition(DCog), which shows how DCog would offer a more complete understanding ofmanufacturing within its greater context, including the social, cultural, andmaterial surroundings. This paper aims to characterize and analyse dock assemblyof forest machines as a complex socio-technical system from a DCog perspective;focusing on the creation of enacted landscapes in this particular setting. The paperalso exemplifies benefits of using the DCog framework in the manufacturingdomain as a way of grasping the assembly workers’ tacit competence and skills.

    Interruptions in the wild: portraying the handling of interruptions in manufacturing from a distributed cognition lens2017Inngår i: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566, Vol. 19, nr 1, s. 85-108Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper presents a study examining interruptionsin the wild by portraying the handling of interruptionsin manufacturing from a distributed cognitionlens. By studying how interruptions occur and are handledin the daily activities of a work team at a large foundry forcasting heavy diesel engines, we highlight situations whenthe propagation, transformation, and representation ofinformation are not supported by prescribed work processesand propose recommendations for how this can beamended. The study was conducted by several visits to theaforementioned factory with cognitive ethnography as thebasis for the data collection. The focus was on identifyinginterruptions and analysing these through a distributedcognition framework as an initial step towards studyinginterruptions in a manufacturing environment. The keyfindings include the identification of three, previouslyundefined, types of interruptions and the conclusion thatinterruptions do indeed affect the distributed workload ofthe socio-technical system and thus the overall productionperformance at the casting line.

    Creating a usable analysis application built on an existing visualization platform2017Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    The advances in research on wireless communications has lead up to the current success of 4G mobile broadband and is currently focusing on designing the upcoming even more advanced fifth generation (5G) networks. The type of research behind this typically generates large quantities of data and requires efficient analysis in order to achieve tangible results. To enable this analysis, visualization of the data is used to give the researchers the needed insights. For this master thesis project an existing platform will be analyzed with the goal of, by utilizing the platform, creating a powerful, useful analysis application with the necessary and desired tools. The platform can access data produced from research simulations and visualize them through different types of useful charts. However, it has up until now lacked some important functionality, mainly letting the user modify and alter the visualization to aid in the analysis. It furthermore requires knowledge and experience before being useful. To solve this, there existed a need of extending the platform with new tools and functionality to give the user more control and possibilities and to simplify the usage. The thesis resulted in a functioning analysis application that gives the user many necessary features to effectively analyze data. The result fulfilled the set requirements with improved and added views, extended tools and optimized performance.

    The Turkish International Roll-on/Roll-off Industry: Analysis of the Industry and the Strategies of the Companies on the European Lines2017Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [en]

    Ro-ro transportation is a type of short-sea shipping where the wheeled cargo is transported by ro-ro (roll-on/roll-off) vessels.This transportation type is different than other sea shipping transportations such as container shipping. The international ro-ro industry between Turkey and Europe has grown significantly in the past decades mostly due to the problems that Turkish international freight operators faced on the land routes through European countries. Currently, there are three companies operating ro-ro on the European lines; U.N. Ro-Ro, Alternative Ro-Ro and Ulusoy Ro-Ro. U.N. Ro-Ro is the market leader with 65% market share and is also the fourth largest ro-ro operator in terms of capacity in lanemeters. Alternative Ro-Ro is the second largest ro-ro operator with 23% market share and Ulusoy Ro-Ro is the third with 12%. The companies emerged at different times in the market with different resources and strategies. Through archival studies and interviews, this thesis focuses on the analysis of the ro-ro industry with PESTLE Analysis and Michael Porter’s Five Forces and the strategies of the existing ro-ro operators in the market. PESTLE Analysis presented that factors that affect export and import volumes such as political and economical factors affect the ro-ro industry the most. Porter’s Five Forces Analysis presented that the power of buyers, the threat of land transportation as substitute and rivalry are high, the power of suppliers is medium, and the threat of new entrant and container shipping as substitute are low. The most commonly used strategies are differentiation, diversification, alliance and specialization strategies.

    Numerical simulation of the linearised Korteweg-de Vries equation: Diploma work (15 HP) Uppsala University Division of scientific computing2014Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The first main focus in the present project was to analyse the boundary treatment of the linearised Korteweg-de Vries equation. The second main focus was to derive a stable numerical solution using a high-order finite difference method. Since the model involved a third derivative in space, the numerical treatment of the boundaries was highly nontrivial. To aid the boundary treatment high-order accurate first and third derivative finite difference operators were employed. The boundaries are based on the summation-by-parts (SBP) framework, thereby guaranteeing linear stability. The boundary conditions were imposed using a penalty technique. A convergence study was performed where the derived numerical solution was compared with an analytical one. Fourth order accurate Runge-Kutta was used to time-integrate the numerical approximation. Measuring the rate of convergence, q, yielded q = 4 for 4th order accurate SBP-operators and q = 5.5 for 6th order accurate SBP-operators. Thus the convergence study proved the accuracy and stability of the numerical solution derived with the SBP-methodology.

    Jämförelse av reningsmetoder för tvättvatten från bussar2018Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Alla fordonstvättar för Stockholms bussar i kollektivtrafiken har olika varianter på efterföljande vattenrening. Trafikförvaltningen önskar prova en ny sluten reningsmetod som inkluderar en indunstare som koncentrerar föroreningar och avdunstar vattnet för i princip 100 % vattenrecirkulation. Arbetets syfte är därmed att jämföra den slutna reningsmetoden med de tre nuvarande reningsmetoder som har en vattenrecirkulation på 80 %. En av de nuvarande metoderna består av biologisk rening med efterföljande poleringssteg, den andra av hydrocykloner med efterföljande elektroflockation och den tredje av ozonrening. Jämförelse baserades på för-och nackdelar utifrån reningsresultat, drift, underhåll, drift-och underhållskostnader samt livscykelkostnader.

    Studien visade att en sluten metod med indunstning genererar en högre avskiljning av föroreningar och återanvänder allt renat vatten till tvätthallen, på så vis belastas inte det kommunala spillvattennätet. För den biologiska reningen och elektroflockationen finns en tydlig tendens för överskridande av utsläpp av zink. För elektroflockationen finns även en tendens för överskridande av uppsamlad halt bly, nickel och krom.Indunstningen medför också en del högre kostnader. Grundinvesteringen är upp till fem gånger så stor och elförbrukning upp till sex gånger dyrare jämfört med de nuvarande reningsmetoderna.

    Indunstningen medför en högre energiförbrukning men genererar överskottsvärme som upp till 80 % kan återföras via fläktluftvärmare för att värma upp tvätthallen. Uppvärmning att tvätthallar är den mest kostsamma energiförbrukning på bussdepåerna och på så vis kan den kostnaden minska väsentligt.

    Totala kostnader för maskinutrustningarnas livslängd beräknades utifrån nuvärdesmetoden som räknar om alla betalningar över tid till tidpunkten vid investeringen. Livscykelkostnaden visade sig vara lägst för ozonrening främst då metoden inte kräver några större driftkostnader. Den mest kostsamma livscykelkostnaden var för den biologiska reningen. Det fanns dock indikationer på att vattenrecirkulationen inte fungerar som den ska då färskvattenförbrukning var den dyraste driftparametern.

    Crowdfunding i start up-företag: En fallstudie om delägarbaserad crowdfunding som finansieringsmetod2015Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    This study was performed to examine the performance of an equity based crowdfunding campaign, as well as seeking to describe the risks, complications and the opportunities that this kind of funding brings. The study was conducted by an empirical case study of a company that was about to initiate an equity based crowdfunding campaign.

    The conclusion is that the planning of an equity based crowdfunding campaign is time consuming and requires knowledge in many different areas. Therefore it is important to identify in which areas skills and resources already are available within the company, and where it must be obtained through a learning process.

    The report also highlights that equity based crowdfunding, because of legal restrictions surrounding the issue of unlisted shares, can not be marketed as other types of crowdfunding. This leads to the conclusion that those who invest in equity based crowdfunding do not necessarily belong to the crowd that crowdfunding is generally associated with. Arguments can be made that this crowdfunding model rather resemble traditional angel networks.

    A technical study was also made about the company's products. The result of the technical study can be used by customers to get a clearer understanding of the company's products, but also by the company itself as a good insight into how their products work in practice and to develop the existing products.

    Förbättringsarbete inom rollfördelning2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Efter att den valda organisationen genomgått en större omorganisering är den idag välmående. Omorganiseringen innebar nedskärning av personal och nedläggning av produktion. Efter omorganisationen kvarstod arbetsuppgifter, projekt och roller utan resurser. Organisationen befinner sig inte längre i överlevnadsfasen men organisationen har inte stannat upp för att stabiliseras efter överlevnadsfasen. Att stabilisera organisationen innebär att arbeta vidare med utveckling av ledarskapet, kommunikationen, processer och projekt i förbättringsområdet rollfördelning. Under studien blev det möjligt att genomföra sju intervjuer, två observationer och dokumentinsamling. Rollfördelningen innebär att medarbetarna går in i varandras områden eller arbetsuppgifter trots att det finns processer som visar avgränsningarna mellan de olika områdena. Det skapar otydliga roller, avgränsningar mellan arbetsområden och kommunikationsbrist. I studien presenteras en kartläggning av den valda organisationens nuläge och förbättringsförslag samt implementeringsplan.

    Skräppost eller skinka?: En jämförande studie av övervakade maskininlärningsalgoritmer för spam och ham e-mailklassifikation2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Spam messages in the form of e-mail is a growing problem in today's businesses. It is a problem that costs time and resources to counteract. Research into this has been done to produce techniques and tools aimed at addressing the growing number on incoming spam e-mails. The research on different algorithms and their ability to classify e-mail messages needs an update since both tools and spam e-mails have become more advanced. In this study, three different machine learning algorithms have been evaluated based on their ability to correctly classify e-mails as legitimate or spam. These algorithms are naive Bayes, support vector machine and decision tree. The algorithms are tested in an experiment with the Enron spam dataset and are then compared against each other in their performance. The result of the experiment was that support vector machine is the algorithm that correctly classified most of the data points. Even though support vector machine has the largest percentage of correctly classified data points, other algorithms can be useful from a business perspective depending on the task and context.

    First Impressions Last: Ett förbättringsarbete av introduktionsprocessen hos Sandviken kommuns Servicekontor2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Introduktion för nyanställda ger en första bild av verksamheten och har stor betydelse vad avser nya medarbetares trivsel. En bristfällig introduktion kan således vara avgörande för om en person väljer att stanna kvar i verksamheten eller leta efter andra alternativ. Inför examensarbetet genomfördes en förstudie hos Sandviken kommuns Servicekontor för att ta reda på varför de har svårt att hitta såväl som att behålla vikarier. Utifrån förstudien konstaterades att Servicekontorets avsaknad av ett introduktionsprogram med rutiner var grundorsaken till majoriteten övriga problem inom vikarieprocessen. Syftet med studien var att ta fram och implementera ett introduktionsprogram med rutiner.

    För att kartlägga nuläget och eventuella förbättringsområden genomfördes åtta semistrukturerade intervjuer, en observation och en dokumentinsamling. Empirin analyserades mot det teoretiska ramverket med avstamp i Human Resource Management (HRM) och offensiv kvalitetsutveckling. Analysen påvisade att Servicekontorets introduktion karaktäriserades av den individualiserade socialiseringsmetoden snarare än den institutionaliserade. Ett negativt resultat då forskning visar att anställda tenderar att ha en positiv inställning till arbetsplatsen och i högre grad känner att det passar in om de genomgått den institutionaliserade socialiseringsmetoden. Likaså visar den senare metoden på lägre personalomsättningsnivåer.

    Med utgångspunkt i tidigare forskning utformades det nya introduktionsprogrammet enligt den institutionaliserade socialiseringsmetoden. Vidare har det nya programmet utformats utifrån faktorer som krävs för ett framgångsrikt mångfaldsarbete. Programmet innehåller generell information som underlättar introduktionen i allmänhet och det självständiga arbetet i synnerhet. Avslutningsvis har det nya programmet kvalitetssäkrats utifrån hörnstensmodellen.

    Det är viktigt att komma ihåg att kvalitetsarbete är ett ständigt pågående arbete och inte ett projekt med en början och ett slut. Att implementera ett introduktionsprogram med rutiner är inte tillräckligt för att försäkra att vikarierna stannar hos Servicekontoret. Det nya introduktionsprogrammet lägger grunden för ett bra mottagande och första intryck av Servicekontoret. Ansvaret att förvalta resultatet från den här studien och arbeta vidare med fortsatta förbättringsområden ligger hos ledningen på Servicekontoret.

    Abstract [en]

    The structure of the thesis is based on opportunities to attract businesses to the region, the need of establishments in the region and benchmarking with establishment strategies of other cluster initiatives. The identified opportunities are the local business relationship with ABB, the prerequisites of life quality in the region and the availability of financial support. Further on has a number of opportunities to be developed been identified; diversification of the existing businesses, an expansion of the cooperation with universities and to simplify the contact with local authorities. Challenges that HVV is facing is: creating a more dynamic labor market, secure long-term labor supply, spread the image of the brand HVV and finally putting HVVs geographic scope. Two of the identified needs of establishments are strategically important: to establish a third-party logistician and commercializing systems for distributed generation and energy storage. Strategically HVV should identify their core areas and limiting operations to areas with strong growth potential.

    CFD Simulations of the New University of Sydney Boundary Layer Wind Tunnel2012Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Using Computational Fluid Dynamics Simulations, the flow in the new University of Sydney closed circuit wind tunnel has been analyzed prior to the construction of the tunnel. The objective was to obtain a uniform flow in the test section of the wind tunnel while keeping the pressure losses over the tunnel as low as possible. This was achieved by using several flow-improving components such as guide vanes, screens, a honeycomb and a settling chamber. The guide vanes were used in the corners and in the diverging part leading into the settling chamber, giving a significant improvement of the flow as they prevent it from taking undesired paths. The settling chamber is used to decelerate the flow before it is accelerated when leaving the settling chamber, a process which reduces the turbulence in the flow. Screens were used in the settling chamber to further improve the flow by imposing a pressure drop which evens out differences in the flow speed and reduces the turbulence. The honeycomb, which is situated in the end of the settling chamber, makes the flow more uniform by forcing it to go in only one direction. A uniform flow was obtained using three screens and one honeycomb together with the guide vanes and the settling chamber.

    Collaboration in practice: A multiple case study on collaboration between small enterprises and university researchers2018Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    University-industry collaborations (UICs) have been hailed as key for Sweden's innovativeness and economic growth. Similarly, building research and innovation policies for the promotion of collaboration between universities and industry have become a cornerstone for many other European countries.

    In academic literature there has been an emphasis on efficiency, facilitation, effects and values obtained in UICs. They have been widely studied, both in terms of the reasons why they are formed, their structure and the effects they create, but not much in terms of how they work on a daily basis. There is less attention in the literature to analyse or problematise how UIC work is carried out when a connection has already been formed or is repeatedly enacted. Additionally, there is also a lack of studies looking at small firms UICs. Through identifying a lack of perspective in the UIC literature this thesis builds on the recent developments in practice theory in addressing some of the gaps found. It thus analyses these collaborations from a perspective not present in the literature in pursuit of how UICs are carried out.

    Through four embedded case studies between small enterprises and university researchers the thesis questions some of the assumptions made in the UIC literature and policy documents. First of all, through the practice theory lens, the thesis shows how the creation of a node/linchpin, a boundary object or a broker, between university and industry is instrumental in enabling collaboration work to take place. Secondly, being able to work together successfully does not equal outcomes sought after by policy organisations. Nevertheless, a general conclusion is that there were valuable outcomes for both the companies and the researchers, confirming previous research on UICs. But, these benefits were often difficult to put into clear numbers or metrics and appeared only after a very long time.

    The thesis argues that policy (and associated organisations) should promote the connection between a research site/practices and a company site/practices rather than pushing for a joint practice. In such a way UICs can be valuable for both researchers and companies.

    Förbättring av ritningshantering hos ABB Industrial Automation Control Technologies2018Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    Cost of poor quality describes what the lack of quality costs an organization. By understanding what the concept is and how it can be translated into a specific organization, it creates the conditions for eliminating them, and it can generate a saving of up to 30% of the organization's turnover.

    The study has been carried out at ABB Industrial Automation Control Technologies in Västerås within the group ABB AB. This work has focused on visualizing the problem and how it could be attacked. The purpose of the thesis is, "… to generate evidence about the management of drawings, as well as to propose measures that can improve this process. The aim is also to help ensure that there is a process where suppliers always produce based on the right and most recent edition. "

    The processes of drawing management have been visualized based on information from interviews, observations and secondary data that have been based on information from routines together with governing documents. Thereafter, deficiencies in this drawing management process have been identified and also the causes.

    The result from the thesis is a process mapping with identified shortcomings and the causes of these. A specification has been prepared for guidelines on how ABB Industrial Automation Control Technologies will work with improvements on this process.

    Förutsättningar för lyckade projekt i komplexa miljöer: En studie om projektkomplexitets inverkan på kvalitetsarbete2018Independent thesis Advanced level (professional degree), 20hpOppgave
    Abstract [en]

    Studies show that the success of a construction project depends onits initial design work. Thus, it’s interesting to investigate howensuring design work quality is done. Since the mid 70’s SKB has worked on how the final repository of spent long-lived nuclearfuel should be built to satisfy the requirement of total repository from the people and environment for a period of 100,000 years. The project is large and consists of many subprojects; where one of them is carried out by WSP. The quality work in this project has been evaluated to see how the ensuring of reaching required quality and expectations.

    This type of project can be assumed to be complex both to control and execute, in terms of structural complexity, technical complexity and uncertain complexity. By characterizing the project due to its surroundings, content and organizational behaviour and to them apply the dimensions of complexity the aim of the study is to identify how the complexity has effect the quality work. To understand this, semi structured interviews with the project organization has been done.

    The result of the study shows that especially the structural complexity, mainly by the number of collaborated departments, affects the quality work. Also uncertain complexity affects the quality work, due to unclear contract between client and supplier. To receive better quality work in the future the coordination between different departments needs to be better. This involves for example establish project specific methods and routines, for all in the project to use. To be able to deliver successful projects one presumption is that client and supplier agreed on what is to be delivered. If the project scope isn’t clear agreedupon, a satisfied client can never be reached.

    Marknadsundersökning inom datacenterbranschen: Undersökning av tekniska inköp, med fokuspå kyllösningar2013Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption. But alone it does not justify an additional investment. Data center downtime has a negative impact financially and can also adversely affect various functions critical to society. Therefore, the dependability of the equipment is still a priority, but reliability is now considered to have reached such a level that it is considered acceptable and the focus of development has shifted towards energy efficiency.

    The interview study is complemented by an investment-theory review of articles and books on related subject matter. This subject matter is linked directly or indirectly to disposition of investment in the data center industry. The framework developed from the review is then compared to the interview results. Results indicate that decision and investment theory in many cases can also be applied to data center investments. Theories that are more environmentally and socially oriented, such as Triple Bottom Line, are not consistent with the empirical data from the interviews. The investment decisions are also influenced by the current high availability and high reliability of data centers, which is the reason why the industry is rife with inertia, conservatism and skepticism to new solutions. Consequently, the parallel between data centers and high risk organizations, HRO, brought a new approach to how priorities are evaluated within HROs, namely that it is possible to combine high reliability with a low environmental impact.

    The results of the study are used as the basis to establish a marketing plan for the company SEE Cooling, a startup company that supplies cooling equipment. This marketing plan is based on the models for: Network analysis, Porter's five forces analysis, SWOT analysis and Kotler's marketing mix. The resulting marketing plan offers proposals on how SEE Cooling shall navigate their business network to overcome conservatism and promote their products, and illustrates potential difficulties.

    Analys av kvalitetsbristrapporter vid en tillverkande industri: En fallstudie utförd i enlighet med Sex Sigmas projektmetodik DMAIC2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The thesis has been carried out in a manufacturing industry with high quality requirements both from customers and national regulatory frameworks for medical devices. To meet these requirements the site is certified by ISO 9001, ISO 13485 and ASME as well as they continuously work by the principles of Lean and Six Sigma. For different types of defects in the production, such as quality defects on materials, non-conformance reports are established for monitoring, analyzing and statistical logging the problems. Monitoring is done on supplier and item level. However there is no analyzing or monitoring of the type of quality problems. A deeper statistical analyze of various types of defects according to Six Sigma and DMAIC has therefore been seen as relevant to this study. The questions "What types of defects contribute to the largest internal quality costs according to rework and scrap?" "What are the root causes to the defects?" and "Which root causes requires the least resources to be eliminated, while giving the most positive impact if they are?" form the basis of this work. 

    The study has been made in accordance to DMAIC. Various methods and tools from the improvement program Six Sigma has been used for collecting, processing and analyzing data. The methods used for collecting data was collection from database, literature studies, interviews, and observations. The methods used for analyzing data was stratification, triangulation and DMAIC. The tools used was the Kano model, CTQ-analysis, Pareto chart, check sheet, flowchart, bar graphs and cause-effect diagram based on 7M. 

    The results that occurred was that different types of defects in form of indentations or chipped metal items, scratches on plastic and glass tubes as well as scratches on metal items account for the largest proportion of internal quality costs in the form of scrap and rework on avd2. On avd1 the cause of defects that account for the largest proportion of internal costs in the form of scrap and rework does not appear just as clearly. The root causes identified to the occurrence of the defects is insufficient 5S on avd2 as well as in the inventory. Suggestions to the organization for eliminating the root causes are: 

    Short-term solutions: Sort, organize and clean, mostly in assembly halls, to remove all unnecessary items and free space. The storage of steel items should be reviewed as well as how the material is presented for the assemblers.  

    Long-term solutions: A continuous work with 5S, both inside the assembly halls and in the warehouse. Work in accordance with a pull-system instead of today's push-system.

    Utvärdering av datorprogram för användning vid dagvattenutredningar2012Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    The main object of this diploma work thesis is about how computer programs can be

    a tool to use for work on stormwater investigations. The advantage of using a

    computer program compared with calculations made by hand is evaluated and

    discussed. The computer programs that have been used for studies and a sequence of

    testing of the possibilities are Autodesks Storm and Sanitary Analysis and DHIs Mike

    Urban.

    Focus on sustainable development now permeates the building industry. As a result

    stormwater investigations have been conducted in an increasing extent the recent

    years. Stormwater is water produced due to precipitation, such as rain and snowmelt.

    Stormwater investigations normally contain descriptions of existing land use, planned

    land use and suggestions of measures and technical solutions for the future disposal of

    stormwater.

    The initial part of the thesis consisted of literature studies on stormwater and

    stormwater investigations to understand the science. Further literature studies

    where related to hydraulic and hydrologic modeling. An analysis of the interest and

    way of applying these methods among municipalities and sewer companies where

    performed. Literature studies and situation analysis formed the basis for the design of

    the evaluation methodology where a number of key points were chosen and

    followed-up for both programs.

    The results of the thesis shows that there is a big advantage in using computer

    simulations for accurate mapping of the pipe networks provided that you also have

    the means to calibrate the hydrologic and hydraulic models. For less accurate

    analyzes, computer programs may be seen as a tool for data management.

    Discovering the Effects of Sharing Economy for Tourism and Hospitality Industry in the Stockholm and Uppsala Region2020Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The aim of this research is to investigate the current situation of how the growing demand on Peer-to-Peer services (P2P) like Airbnb is affecting the conventional establishments and businesses in the tourism and hospitality (TH) sector in the Stockholm and Uppsala Region. In other words, understanding the effects of the sharing economy (SE) and picturing its place inside (or in the opposite of) the TH industry. By using semi-structured interviews with small to medium size hotel/hostel experts, Airbnb hosts and tourism industry representatives we make an exploratory study and analyze the current situation of the relationship between Airbnb and conventional establishments operating in TH industry. We analyze corporate and marketing strategies and business models being used by incumbents of the industry. Our findings show that the relationship between Airbnb as an accommodation platform in the Stockholm and Uppsala market is not considered as a threat by other actors of TH sector by any means and that there are different factors that could be considered in order to understand this feeling around the Stockholm and Uppsala Region. Some of the discussed factors within the study are the development and growing characteristics of the market together with the regulations currently applied to the P2P platforms within the county. The results also give new study possibilities for researchers that are willing to discover how the Swedish TH industry develops in the next decade in relation to a dynamic customer base in the Stockholm and Uppsala region and in Sweden.
