    Optimisation of Ad-hoc analysis of an OLAP cube using SparkSQL2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    An Online Analytical Processing (OLAP) cube is a way to represent a multidimensional database. The multidimensional database often uses a star schema and populates it with the data from a relational database. The purpose of using an OLAP cube is usually to find valuable insights in the data like trends or unexpected data and is therefore often used within Business intelligence (BI). Mondrian is a tool that handles OLAP cubes that uses the query language MultiDimensional eXpressions (MDX) and translates it to SQL queries. Apache Kylin is an engine that can be used with Apache Hadoop to create and query OLAP cubes with an SQL interface. This thesis investigates whether the engine Apache Spark running on a Hadoop cluster is suitable for analysing OLAP cubes and what performance that can be expected. The Star Schema Benchmark (SSB) has been used to provide Ad-Hoc queries and to create a large database containing over 1.2 billion rows. This database was created in a cluster in the Omicron office consisting of five worker nodes and one master node. Queries were then sent to the database using Mondrian integrated into the BI platform Pentaho. Amazon Web Services (AWS) has also been used to create clusters with 3, 6 and 15 slaves to see how the performance scales. Creating a cube in Apache Kylin on the Omicron cluster was also tried, but was not possible due to the cluster running out of memory. The results show that it took between 8.2 to 11.9 minutes to run the MDX queries on the Omicron cluster. On both the Omicron cluster and the AWS cluster, the SQL queries ran faster than the MDX queries. The AWS cluster ran the queries faster than the Omicron cluster, even though fewer nodes were used. It was also noted that the AWS cluster did not scale linearly, neither for the MDX nor the SQL queries.

    Investigation of a method to extend the use of output data from Scania's Hardware-In-the-Loop simulations: Development of database and search algorithm2014Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In the automotive industry, Hardware-In-the-Loop (HIL) laboratories are used for testing vehicle functions and systems. Swedish heavy truck manufacturer Scania recently upgraded its HIL lab resulting in an opportunity to save all data generated by simulations in the HIL lab for post analysis. Thus, Scania wished to investigate the possibility to extend the use of output data by examining a new test method. The new test method was intended to be used for disclosing a type of error that had not been possible to detect prior to the upgraded HIL lab. The proposed test method was to store tests in a database and to run the tests upon output data generated in the HIL lab. The tests which were to be stored in the database existed as scripts written in the programming language Python. In order to insert tests into the database the data had to be extracted from the Python test scripts. The investigation showed the database test method to be feasible in small scale for some test scripts but the results also indicated weaknesses with the method’s setup. Insertion of data, extracted from test scripts, into a relational database showed to be problematic as the data was highly heterogeneous and did not fit easily into relational tables. For future implementations it is suggested that the method incorporates other information sources complementing the test scripts.

    A Single-Minded Market for Digital Assets?: Copyright clearance of orphan works in the digitisation ecosystem2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This dissertation assesses the Swedish and the United Kingdom (UK) legislative frameworks for cross-border copyright clearance of orphan works in mass-digitisation schemes. By reviewing relevant copyright frameworks and practices around the world, interviewing Swedish and British experts in the field of libraries and copyright, and discussing the national solutions applied in Sweden and the UK, conclusions are drawn to form a roadmap for future policy work in the area.

    The findings are that even though copyright clearance systems for orphan works work well in their national context, they wouldn’t be transferable to a cross-border context due to the different legal and societal traditions in the EU Member States. Solutions for cross-border access could be a general copyright law exception (which is a time-consuming process and therefore less usable in practice in the next 5-10 years), create and build on rightsholder registers with increased collaboration with CMOs, changed management of digital collections (e.g. only digitising orphan works that are in the public domain), or work towards soft legislative solutions (such as an MoU).

    Lokal sökfunktion: Fallstudie av utvecklandet av Uppsala Universitets sökfunktion2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is a case study of the search function on the University of Uppsala’s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical. Without a common strategy how to handle information is it very difficult to make good searches on the web site.

    Harness mobility: Managing the off-task property2010In: DESRIST 2010: The 5th International Conference on Design Science Research in Information Systems and Technology 2010, in St Gallen, Switzerland / [ed] Stephan Aier, Springer , 2010Conference paper (Refereed)
    Abstract [en]

    Technological advancements in mobile computing and wireless networks open up to new applications and new user-groups in the mobile workforce. However, a considerable part of the mobile workforce, such as e.g. drivers or healthcare staff, is chiefly performing other tasks than interacting with their computers. As a result, they are not able to pay attention to computer interaction, making them mainly off computer tasks. The aim of the paper is to develop a design theory to manage off-task situations in mobile computing. Interviews were performed with developers of an information system comprising mobile devices for drivers. From the interviews, a design of an artifact and a design theory based on a strategy to automate routine administration task using place awareness is presented. The eight components of IS design theory by Gregor and Jones is applied as a theoretical framework.

    Världsbäst i digitalisering?: En explorativ fallstudie om den pågående digitaliseringsprocessen av den svenska skolan2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Swedish society is constantly evolving and growing into higher levels of digitalisation. The school system plays an important part in creating a nationwide competence regarding the proper use of digital tools, by growing alongside the society as a whole. In the spring of 2017 the Swedish government issued a public document called the national strategy of digitalization, which defines certain goals for the school system to achieve. The Swedish Association of Local Authorities and Regions (SKL) is in the process of developing a plan of action, which is to be a document used for guiding people working within the school system towards reaching the goals within the national strategy of digitalization. A few initial changes have now been made to the general curriculum and it has raised several questions, regarding the good, bad or even unmanageable consequences that such changes will lead to. This study aims to look into the ongoing discussion and define specific areas of future research. A number of key actors with different roles within and in relation to the school system have been interviewed. Among the results is a model depicting several major actors within the digitalization process and how they relate to each other. The theoretical framework TPACK is used to analyze and discuss the complexity of a general level of competence that is required of teachers working within a digitalized school system. Two areas of future research have been defined: (1) Continuous study and evaluation of the action plan; (2) Proper use and integration of digital study material.

    Cloud Computing: Lärplattform i molnet2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The growth of cloud computing has enabled the provision of computer resources online and offers two essential characteristics, illusion of infinite supply and pay-per-use. Learning management systems are currently used extensively by the Swedish universities as learning tools. This brings better opportunities for distance courses and e-learning. To combine cloud computing with a learning management system is now possible and should therefore give the schools benefits. If the Learning management system is hosted as a cloud service by an external provider, so should the requirements be different.

    The purpose of this paper is to investigate whether there are any incentives for rent a learning management system as a cloud service and also investigate if the requirements are different in a rented cloud service. A case study was conducted at Uppsala University and Dalarnas University, in order to compare a learning management system installed on their own server with a learning management system rented as a cloud service. 

    The result of the study proves that there are advantages to rent a learning management system as a cloud services. In terms to the requirements, there are no great differences. An important requirement when the learning management system is hosted by a supplier is that there is a good dialogue and that the organization relies on the supplier.

    Mobil teknik och mobilt lärande: ett stöd för skola och vård för effektvisering av lärandet och arbete2006Report (Other (popular scientific, debate etc.))
    Abstract [en]

    Mobilitet hos människor har ökat inom många områden i och med utvecklingen och framväxten av den mobila teknologin. Ett av de områden som har blivit påverkat av denna tekniska utveckling är lärande och utbildning både inom arbetslivet och inom skolvärlden. Idag beräknas många yrkeskategorier tillbringa mer än halva sin arbetstid utanför arbetsplatsen. Antalet abonnenter som har tillgång till trådlöst Internet förväntas öka lavinartat under det närmaste decenniet. Digital information och inlärningsmaterial ryms redan nu i våra fickor och vi har möjlighet att koppla upp oss mot varandra och kommunicera oavsett plats och tidpunkt.

    Syftet med rapporten är att presentera de olika formerna av lärande, dvs. distanslärande, elektroniskt lärande och mobilt lärande. Betoningen i detta arbete är på den sistnämnda lärandeformen, mobilt lärande. En jämförelse mellan mobilt lärande och livslångt lärande genomförs och likheterna mellan dessa diskuteras. Syftet är också att diskutera användningen av mobilteknik och mobilt lärande inom utbildningsväsendet och vården i syfte att effektivisera lärandet, kommunikation, kunskapshantering och arbete. Detta för att kunna införa och uppnå en optimal form av livslångt mobilt lärande och mobilt arbete i våra skolor och inom arbetsplatser med hjälp av den nya tekniken.

    Enterprise systems Configuration as an Information Logistics Process - A Case Study2007In: Proceedings of 9th International Conference on Enterprise Information Systems: ICEIS-2007, 2007, p. 10-Conference paper (Refereed)
    Abstract [en]

    In this paper, we suggest using rule-based descriptions of customer’s requirements for Enterprise Systems implementing Information Logistics. The rules are developed from the users’ requirements and inserted as schedules to the Enterprise System. The output, from testing these rules, is a list of modules and parameter setting to configure the system. By using rules, we can, at least partly, automate the configuration process for traverse the several modules and thousands parameters there are in an Enterprise System. From the list, we can select the modules and the parameters that meet the customer’s requirements. Then these selected modules and parameters are visually presented through a kind of Unified Modeling Language diagrams, to support the user investigation and then to configure the system either manually or automatically. Every attempt to match a customer’s requirement to the contents of the knowledge base within the Enterprise system can be thought of as an Information Logistics Process. The output from such a process must be examined by the user, which can give rise to a new call to the Information Logistics process. In other words the configuration work is done through a dialogue between the customer and the knowledge base of the Enterprise system.

    Information coordination using Meta-Agents in Information Logistics Processes2008In: Proceedings of Knowledge-Based and Intelligent Information & Engineering Systems: KES2008, Berlin, Heidelberg: LNCS/LNAI, Springer-Verlag , 2008, p. 788-798Conference paper (Refereed)
    Abstract [en]

    In order to coordinate and deliver information in the right time and to the right place, theories from multi-agent systems and information logistics are combined. We use agents to support supply chain by searching for company specific information. Hence, there are a vast number of agents working at the Internet, simultaneously, which requires supervising agents. In this paper, we suggest using meta-agents to control the behaviour of a number of intelligent agents, where the meta-agents are working with coordination of the communication that takes place in a supply chain system. As an example, we look at a manufacturing company receiving orders on items from customers, which need to be produced. The handling of this distributed information flow can be thought of as an Information Logistics Processes and the similarities of the functioning of processes and intelligent agents’ behaviour are illuminated.

    Motstånd och problem vid implementeringen av ERP-system: En litteraturstudie av förändringshantering och motstånd vid implementeringen av ett ERP-system. Studien ger även förslag på förebyggande åtgärder baserat på dokumenterade fallstudier2011Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this paper was to identify factors that give rise to resistance behaviours when implementing ERP-systems. The purpose was also to find ways to prevent these resistance behaviours.Methodology – This paper was conducted through examination and use of a methodology called documents. The paper was built upon existing secondary data. The secondary data was made up of articles and books from world leading academic journals in the area of ERP-implementation.Findings and results – The findings of this paper suggests that all ERP-implementations will face human resistance of some kind and that the treatment of these resistance behaviours is crucial for a successful implementation project. The paper identified important resistance factors that need to be handled: Low commitment from top management, inadequate training and education, a project group with little influence, experience and skills, poor change management and passive management styles, system quality, system reliability, poor business vision and poor strategy plans. The paper also identified the planning phase of an ERP-implementation to be the most crucial phase in the whole project. The paper presents ways to prevent the resistance threat through some important factors: A clear business plan and vision of the project is needed and this vision must be visible to people using the system, strong support from top management and the board is needed for funding and influence on lower levels of organizations, good anticipation of changes in processes connected to the implementation, support and communication with relevant stakeholders, a strong and influential project group, training and education to overcome knowledge barriers and developed change management strategies.Originality – This paper provides an examination and summary of the most critical factors that influence resistance behaviours when implementing an ERP-system and also provides a model that can be used in organizations when facing an implementation project.Keywords – ERP, ERP-implementation, resistance behaviours, ERP-implementation phases.

    Suggesting Points-of-Interest via Content-Based, Collaborative, and Hybrid Fusion Methods in Mobile Devices2018In: ACM Transactions on Information Systems, ISSN 1046-8188, E-ISSN 1558-2868, Vol. 36, no 3Article in journal (Refereed)
    Abstract [en]

    Recommending venues or points-of-interest (POIs) is a hot topic in recent years, especially for tourism applications and mobile users. We propose and evaluate several suggestion methods, taking an effectiveness, feasibility, efficiency and privacy perspective. The task is addressed by two content-based methods (a Weighted kNN classifier and a Rated Rocchio personalized query), Collaborative Filtering methods, as well as several (rank-based or rating-based) methods of merging results of different systems. Effectiveness is evaluated on two standard benchmark datasets, provided and used by TREC’s Contextual Suggestion Tracks in 2015 and 2016. First, we enrich these datasets with more information on venues, collected from web services like Foursquare and Yelp; we make this extra data available for future experimentation. Then, we find that the content-based methods provide state-of-the-art effectiveness, the collaborative filtering variants mostly suffer from data sparsity problems in the current datasets, and the merging methods further improve results by mainly promoting the first relevant suggestion. Concerning mobile feasibility, efficiency, and user privacy, the content-based methods, especially Rated Rocchio, are the best. Collaborative filtering has the worst efficiency and privacy leaks. Our findings can be very useful for developing effective and efficient operational systems, respecting user privacy. Last, our experiments indicate that better benchmark datasets would be welcome, and the use of additional evaluation measures-more sensitive in recall-is recommended.

    The impact and power of Business Intelligence (BI) on the Decision making process in Uppsala University: A case study2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Information Systems (IS) is the use of Information Technology (IT). Business Intelligence (BI) is a specific type of IS. A BI system is an information system that uses tools to produce and deliver information. BI has become very important in the recent era as the organizational environments are getting more complex and changing faster than ever before.

    Research on BI uses in academia has been somewhat limited so far. Most decisions in a university are made based on large amounts of data from internal and external sources. So, a BI tool is necessary there in operational and strategic decision making, and also to compete well in the global environment which is very important for an international university like Uppsala. We made a case study on the large BI tool at Uppsala University. The tool has been used for more than ten years with around five hundred regular users currently. The system is called GLIS (in Swedish: Generellt Lednings Informations System) for Generalized Management Information System. It would be very interesting to investigate how the adoption of this BI system may influence the decision making process in Uppsala University, and thus it becomes the main purpose of this thesis.

    An inductive approach using a qualitative method was used in this thesis. The data collection was carried out by interviewing seven experts at Uppsala University and from some documents provided by them. Techniques from the grounded theory approach were applied for analyzing data. Our analysis shows positive effects of GLIS in Uppsala University with big improvements in decision making. The thesis draws a conclusion that the BI tool does affect the decision making process in UU as decision making activities take less time, provide better quality decisions, and are much easier using the tool. The thesis also suggests some possible improvements of GLIS for a better functionality and more user involvement. For IS practitioners, the thesis shows the power of IS tool in decision making and university management. For the IS research community, the thesis contributes with the extension of existing theory on BI uses in academia.

    Users’ intention to systematically integrate healthcare information technology in a mandated context: A continuance perspective2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis aimed to investigate the determinants of system satisfaction and the intention to systematically integrate a system from a continuous use perspective, where system use is mandatory. For this purpose, two identical questionnaires were distributed to collect data, 15 months apart. Respondents taking part in this study are healthcare multi-professionals who pertain to a work-group at an intensive care unit, at a large Swedish hospital. To evaluate the questionnaire data a research model was conceptualized, grounded in prior information system continuance research. It is also significantly influenced by the UMISC metamodel, conceptualized and suggested by Hadji & Degoulet (2016). The collected data was then analyzed using a two-stage analysis where one aspect was comparative, i.e., a comparison of the data between the two questionnaires, and the other was explorative, wherein research model constructs and their relations were evaluated. This analysis provided significant insight into the determinants of system satisfaction. However, regarding the determinants of the intention to systematically integrate as well as the research model itself, neither could be validated in this study. Nevertheless, these results allowed for a modified model to be conceptualized, with potentially promising results.

    Business Intelligence in Uppsala Univeristy - Do academic institutions practice what they preach?2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Business Intelligence (BI) is not a new concept. However, it is still complicated to work with it due to the different views and ways of implementation. This study has adopted an organisational oriented approach of BI: getting the right information, to the right people, at the right time. It was found in this study that poorly implemented BI features and inadequate information infrastructure may lead to workarounds in order to compensate for missing or lacking features and systems.

    This case study has been conducted at the faculty of Social Sciences of Uppsala University (UU) where a set of interviews were conducted to individuals on one of the key positions at the university; the Director of Studies (DoS). The aim was to map out the key processes and head activities of the DoS’s and evaluate them through the BI view of this thesis. Being the conclusion a concrete mapping of the DoS head activities as well as BI assessment of the current situation of the studied departments. Some improvements have been proposed in order to remedy the lacking of valuable and critical features and systems. However, it was found that the current system infrastructure and problem area is too immature in order to implement any form of integration. Several studies on key positions and influential systems need to be conducted in order to exhaustively map out and discover the problem area.

    Developer usability testing: A real world example2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The iPhone has thanks to its multitouch interface, size and connectivity change the way we communicate. To fully utilize this technology we can involve users in the development process to help make highly usable software applications. One way to do this we somehow need to get the users to use our systems. What techniques are there to do this? And will they fit our product? Are there any way we can involve the users in the development process of an iPhone application, in this thesis I investigate if this can be accomplished by conducting usability tests with users on an iPhone application. The usability testing gives an insight into how the users work with and adapts to the users interface. The questionnaires given to the participants gave insight into how the users considered the usability and usefulness of the application. This data gave the development much needed data on the application to make it better and more usable. Since earlier research into user involvement have shown a strong connection to usable software and usability testing could be integrated successfully into the development by the single programmer, the conclusion can be drawn that single developer that incorporates usability testing into the development process as a form of user involvement makes more usable software. The usability was tested on an iPhone application built for an American online classified ads website.

    The AI Revolution: A study on the present and future application and value of AI in the context of ERP systems2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Business leaders around the world are expressing equal amounts of excitement and urgency for implementing artificial intelligence (AI) technologies. Yet the upcoming AI revolution is clouded with uncertainties and misconceptions. In this thesis, the business value and application potential of AI were studied in a context of enterprise resource planning (ERP) systems through a case study at a consultancy firm with small- to midsize clients. Three research questions were posed and answered: how can, or do, organizational processes covered by ERP systems benefit from AI, what AI features do customers typically request when ordering ERP systems, and is AI adopted with the purpose of reducing costs or increasing revenue?

    Using a framework for data analysis, multiple organizational processes covered by ERP systems were explored through interviews with ERP experts. The results indicated that small- and midsize companies were still primarily requesting and working to implement basic, incremental AI with the purpose of reducing costs through automations. Future leaders may instead need to implement AI that fundamentally reinvents their business processes, with the purpose of increasing revenue through augmentations. Overall, while some organizational processes have already been improved with AI solutions, many processes have yet to be AI-powered in the ERP solutions sold by the consultancy firm examined in this study. However, the consultants of the firm express great positivity for the untapped potential of AI, and many further AI solutions are being developed.

    Big data: En studie om dess affärsnytta samt dess utmaningar och möjligheter, med fokus på detaljhandeln2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Enormous amounts of data is created and stored today, all the while only a small amount of data is being analysed and used. Big data is a term that has circulated for years, however in recent years its meaning have been increased. More enterprises are starting to open their eyes for big data, while few understand how to actually use it. Some even ask themselves: is there a business benefit? With a focus on the retail industry, we examine whether there is a business benefit with using big data, and above all what challenges and opportunities are connected to it. Terms such as business intelligence and analytics are discussed in the relationship to big data. In this qualitative study, three experts from different enterprises; IBM, Knowit and Exor, have been interviewed. The results from the interviews has been connected to the theory from the literature around the subject, and has been compared in the analysis. All identified challenges and opportunities have been listed, and among the conclusions can the ethical and human factors be seen to have a major importance, and that the business benefits can be dependent of an enterprises’ size and market. The essay is written in Swedish.

    Towards a Socio-Institutional Ontology for Conceptual Modelling of Information Systems2015In: Advances in Conceptual Modeling: ER 2015 Workshops AHA, CMS, EMoV, MoBID, MORE-BI, MReBA, QMMQ, and SCME, Stockholm, Sweden, October 19-22, 2015, Proceedings / [ed] Jeusfeld, Manfred A., Karlapalem, Kamalakar, Springer International Publishing , 2015, p. 225-235Conference paper (Refereed)
    Abstract [en]

    Most work on ontologies for conceptual modelling is based on the assumption that conceptual models represent a pre-existing reality, which they should faithfully reflect. This paper suggests an ontology for conceptual modelling of institutional domains taking into account also the prescriptive role of conceptual models, thereby supporting the design of information systems. The paper draws on the current ontological discourse in information systems engineering; descriptive vs prescriptive conceptual modelling; socio-materiality in terms of clarifying the relationships be-tween physical and social domains; and ontological differences between (physical) properties and rights. The results of the paper can be used to support conceptual mod-elling in business analysis, in particular requirements elicitation of regulative aspects.

    Blockchain Technology and Smart Contracts: Privacy-preserving Tools2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this Master's thesis is to explore blockchain technology and smart contracts as a way of building privacy-sensitive applications. The main focus is on a medication plan containing prescriptions, built on a blockchain system of smart contracts. This is an example use case, but the results can be transferred to other ones where sensitive data is being shared and a proof of validity or authentication is needed. First the problem is presented, why medication plans are in need of digitalisation and why blockchain technology is a fitting technology for implementing such an application. Then blockchain technology is explained, since it is a very new and relatively unfamiliar IT construct. Thereafter, a design is proposed for solving the problem. A system of smart contracts was built to prove how such an application can be built, and suggested guidelines for how a blockchain system should be designed to fulfil the requirements that were defined. Finally, a discussion is held regarding the applicability of different blockchain designs to the problem of privacy-handling applications.

    Design of Stand Alone Renewable Power Supply Systems on Futuna Island, Vanuatu2011Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This Master’s Degree project has been performed on behalf of Vanuatu Renewable Energy and Power Association. The purpose of the project was to suggest the design of stand-alone renewable power supply systems on Futuna Island in the Republic of Vanuatu. Futuna is the easternmost island in Vanuatu with a population of about 400 people. The island covers an area of just 13 km2. The proposed sites for power production were the villages of Mission Bay, Matangi, Herald Bay and Iahsoa. In Mission Bay and Matangi the power should be produced by wind turbines and in Herald Bay and Iahsoa, solar modules are proposed.

    The results of the study showed that some parts of Futuna Island can be suitable for wind power production and wind speeds in the order of 5-7 m/s are suggested. However, wind monitoring on the sites are required to estimate the exact potential. Furthermore, the study showed that there is less uncertainty involved with estimating the power output from the solar modules. In addition, solar power proved to be more reliable and less vulnerable to local variations in weather and topography. Solar modules are therefore considered more appropriate for small scale power production on the island, at least until the wind climate is better known.

    The results of the study also showed that proper sizing of battery banks and cables are essential to increase the efficiency and lifetime of the systems. If there are insufficient financial resources in the project, it is therefore recommended in the report to use all resources available to properly size the systems in 1-2 villages rather than to inadequately size the systems in all the villages.

    Dataskyddsförordningens införande: Hur organisationer förhåller sig till dataskyddsförordningen, riskbedömning och efterlevnad2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    On May 25 2018, the General Data Protection Regulation from EU was introduced, which aims to protect individual fundamental rights and freedoms, in particular their right to protection of personal data. The data protection regulation replaces the EU's previous data protection directive and will help prevent the flow of data within the Union being hindered, as the data protection ordinance will apply to all members of EU. This case study aims to gaining an understanding of how different organisations’ risk management against the data protection regulation looks, and whether it will lead to compliance or not. Four Swedish organisations have been studied, presented, and then analysed based on a theoretical framework, designed after the different parts of a general risk management process. The study is of qualitative form and data have been collected through both semi structured and structured interviews. The data protection regulation was not yet implemented during the course of this study, and it was during this time that all parts were designed and the information was collected. The study concludes that the organizations will not be completely compliant against the data protection regulation, which has a number of reasons: They do not take the regulation seriously, they are wrongly doing the change which lengthens the processes, and they delay their compliance due to greater economic profit.

    Dynamic models with quantized output for modeling patient response to pharmacotherapy2010In: Proc. International Conference on Control Applications: CCA 2010, Piscataway, NJ: IEEE , 2010, p. 1029-1034Conference paper (Refereed)
    Abstract [en]

    This article presents a way of modeling patient response to a pharmacotherapy by means of dynamic models with quantized output. The proposed modeling technique is exemplified by treatment of Parkinson's disease with Duodopa ®, where the drug is continuously administered via duodenal infusion. Titration of Duodopa ® is currently performed manually by a nurse judging the patient's motor symptoms on a quantized scale and adjusting the drug flow provided by a portable computer-controlled infusion pump. The optimal drug flow value is subject to significant inter-individual variation and the titration process might take up to two weeks for some patients. In order to expedite the titration procedure via automation, as well as to find optimal dosing strategies, a mathematical model of this system is sought. The proposed model is of Wiener type with a linear dynamic block, cascaded with a static nonlinearity in the form of a non-uniform quantizer where the quantizer levels are to be identified. An identification procedure based on the prediction error method and the Gauss-Newton algorithm is suggested. The datasets available from titration sessions are scarce so that finding a parsimonious model is essential. A few different model parameterizations and identification algorithms were initially evaluated. The results showed that models with four parameters giving accurate predictions can be identified for some of the available datasets.

    Design in Telemedicine: Development and Implementation of Usable Computer Systems2005Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Designing computer systems that effectively support the user is the major goal within human-computer interaction. To achieve this, we must understand and master several tasks. This process must initially deal with the question of knowing what to develop and later, with the question of knowing how to design and develop the system. This view might seem off-target at first, since it does not explicitly mention the goals or functions of the system. However, more often than not, there is no objective goal to aim for that can be formally specified and used as a target criterion that will signal when we have designed an appropriate system. Instead, there is a large set of vague goals – some of which may last through the entire project and some that will not. It is therefore somewhat confounding that most of the current methods of systems development require that these goals are explicitly laid out, in order to steer development.

    For researchers in Human-Computer Interaction, the existence of many varying – and possibly conflicting goals – presents is a great challenge. The constructive main focus on producing usable systems is a matter of understanding this complex situation and knowing how to proceed from there.

    There are many existing approaches that can be used to carry out this complex development process. This thesis presents one approach, based on the notion that the elements that constitute a successful system are also a part of the solution.

    This thesis presents this approach as it is applied to the development of systems for computer-supported work in health care. The projected solution suggests that we need to focus more intently on active user involvement in iterative development that is significantly long-term. The traditional, rather narrow circle of focus that encompasses design, development and evaluation is not sufficient.

    Agentbaserad Simulering som Kontinuerlig Testning av API:er: Utveckling av Simulationsbaserad Testning på uppdrag av Coredination AB2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Ett simulationsbaserat testningssystem tas fram i samarbete med molntjänsten Coredination för att testa deras API (Application Programing Interface) och tjänst. Design och utveckling skedde iterativt med en loggbok för informationsinsamling. Arbetet baserade sig i riktlinjer för agentbaserad simulering framtagna av Macal & North (2010). Simulationstestningen bestod av ett antal agenter som med hjälp utav beteendeträd fattade beslut som liknar de beslut en användare av systemet skulle göra. Från detta togs ett antal lärdomar samt en systemarkitektursmodell fram för att underlätta utveckling av simulationsbaserad testning i andra sammanhang. Dessa lärdomar innefattar att göra en tydlig förstudie, arbeta iterativt med projektet, utveckla för modularitet och initialt för kommunikation mellan agenterna, bygg på nodernas funktionalitet i efterhand, avsätt gott om tid för design av beteendeträd, utveckla endast det absolut enklaste fallet först samt var inte rädd att ändra systemarkitekturen utefter agenternas planerade beteenden.

    Heterogeneous data in information system integration: A Case study designing and implementing an integration mechanism2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The data of different information systems is heterogeneous. As systems are being integrated, it’s necessary to bridge inconsistencies to reduce heterogenous data. To integrate heterogenous systems a mediator can be used. The mediator acts as a middle-layer for integrating systems, it handles transfers and translating of data between systems. A case study was conducted, developing a prototype of an integration mechanism for exchanging genealogical data, that used the mediator concept. Further, a genealogical system was developed to take use of the integration mechanism, integrating with a genealogy service. To test the reusability of the integration mechanism, a file import/export system and a system for exporting data from the genealogy service to a file was developed. The mechanism was based on the usage of a neutral entity model, that integrating systems could translate to. A neutralizing/de-neutralizing mechanism was used for the translating of the data between the neutral entity model, and a system specific entity model. The integration mechanism was added to the genealogy system as an addon. The integration mechanism was successful at integrating genealogy data. The outcomes included: The integration mechanism can be added as an addon to one or more systems being integrated. It was good to have a neutral entity model, together with a neutralizing/de-neutralizing mechanism.

    Nonlinear identification of an anaerobic digestion process2005In: Proceedings of the 2005 IEEE International Conference on Control Applications, 2005, p. 137-142Conference paper (Refereed)
    Abstract [en]

    Anaerobic digestion in bioreactors is an important technology for environmental friendly treatment of organic waste. To optimize and control such processes accurate dynamic models of the process are needed. Unfortunately, modeling of anaerobic digestion often results in high order nonlinear models with many unknown parameters, a fact that complicates controller design. This paper attempts to circumvent this problem, by application of new recursive system identification techniques, thereby radically reducing the degree of the models and the number of parameters. Experiments show that a second order nonlinear model is sufficient for accurate modeling of the system.

    Efficient GPU-based skyline computation2013In: Proceedings of the Ninth International Workshop on Data Management on New Hardware (DaMoN @ SIGMOD), 2013Conference paper (Refereed)
    Abstract [en]

    The skyline operator for multi-criteria search returns the most interesting points of a data set with respect to any monotone preference function. Existing work has almost exclusively focused on efficiently computing skylines on one or more CPUs, ignoring the high parallelism possible in GPUs. In this paper we investigate the challenges for efficient skyline algorithms that exploit the computational power of the GPU. We present a novel strategy for managing data transfer and memory for skylines using CPU and GPU. Our new sorting based data-parallel skyline algorithm is introduced and its properties are discussed. We demonstrate in a thorough experimental evaluation that this algorithm is faster than state-of-the-art sequential sorting based skyline algorithms and that it shows superior scalability.

    Hotbilden i Sverige: En undersökning av den digitala hotbilden mot ett medelstort svenskt företag2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Internet and information technology today has a rather obvious role in the activities of companies and organizations. All cash transactions within and between companies is digitized, communication within the company is done via e-mail, sales and marketing is done largely with marketing and ads on the Internet. This has resulted in economic benefits for companies and organizations, and facilitated the work for them. However, this has also led to new threats have emerged. Companies and organizations is well aware that there are numerous threats that comes with using the Internet and Information Technologies but exactly what those threats are for a mid-sized company in Sweden is not clarified anywhere. New reports made annually by various companies and government agencies around the world but no one puts a medium-sized Swedish business in focus. In this study several reports, made by different companies and government agencies are compared and compiled, too try too make an overview over the threats against a mid-sized company in Sweden. Together with interviews done with key people in the field of IT-security this study identifies the threats, draws conclusions of how to prevent them and also try to take a look into the future to see what threats a mid-sized company or organization can expect in just a matter of years. In the study we notice how all of the IT threats are increasing and that the digital crime are becoming more organized, that some of the key protections for a company is staff training and standard technical solutions such as antivirus software and firewalls. In the future operating systems will no longer be the target for intrusion, but instead web application be the major vulnerabilities. This essay is written in Swedish.

    Message analysis for concurrent programs using message passing2006In: ACM Transactions on Programming Languages and Systems, ISSN 0164-0925, E-ISSN 1558-4593, Vol. 28, no 4, p. 715-746Article in journal (Refereed)
    Abstract [en]

    We describe an analysis-driven storage allocation scheme for concurrent systems that use message passing with copying semantics. The basic principle is that in such a system, data which is not part of any message does not need to be allocated in a shared data area. This allows for the deallocation of thread-specific data without requiring global synchronization and often without even triggering garbage collection. On the other hand, data that is part of a message should preferably be allocated on a shared area since this allows for fast (O(1)) interprocess communication that does not require actual copying. In the context of a dynamically typed, higher-order concurrent functional language, we present a static message analysis which guides the allocation. As shown by our performance evaluation, conducted using a production-quality language implementation, the analysis is effective enough to discover most data which is to be used as a message, and to allow the allocation scheme to combine the best performance characteristics of both a process-centric and a communal memory architecture.

    Open Innovation Software: A study of feature-related problems in idea management systems2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    With the transition from closed to open innovation in recent years, the next trend for companies has been to bring in new ideas from external stakeholders using innovation tools, known as Open Innovation Software (OIS). The most common type of OIS, called idea management systems, allows participants to submit, evaluate, and engage in discussions around ideas. However, implementing software to support innovation is not a sure success and potential problems may arise.

    The purpose of this thesis is to research problems within features in current idea management systems, and to provide guidelines that suggest ways that may eliminate or reduce the impact of the particular problems.

    Interviews were conducted with representatives from five different idea management systems. The respondents demonstrated their systems, which made it possible to gather features and to learn about problems that exist in these systems.

    Five problems within features were found; these were related to engagement, duplicates, idea evaluation, complexity, and bias. Numerous recommendations regarding how the impact of these problems may be reduced have been identified.

    The findings of this thesis show that Problems with engagement is best dealt with using features that delivers better feedback in order to give more motivation to the participants. As for managing duplicates, it is recommended to implement a feature that suggests similar ideas during the idea submission phase. It was found that allowing users to have an unlimited amount of votes should be avoided. To prevent bias, managers should be careful of having features that displays idea ratings before users have casted their vote, features that allow users to edit their casted vote unless an idea has been edited,  and  for instance features that show ideas in order of popularity.

    Legacy Data Migration: A pilot study on the methodological feasibility of conversion and enhancement of electronic resources.2004In: Joint International Conference of the Association for Literary and Linguistic Computing and the Association for Computers and the Humanities: Göteborg University, June 11 - 16, 2004., 2004Conference paper (Refereed)
    Abstract [en]

    In this paper we will describe a pilot study based on two different subsets of electronic resources to be used in the Virtual Corpus system developed at the Oxford Text Archive (OTA).

    The Virtual Corpus system is designed to make the OTA more useful for researchers by enabling the selection of texts for a corpus on basis of metadata categories in the TEI header resource description. Currently these categories include such fields as language, date, genre, author etc. (Berglund & Wynne, 2003). In order to make the Virtual Corpus system (VC) even more useful the texts would benefit from data enhancement.

    This pilot study's aim is to evaluate the necessary procedures for enhancing the metadata available in the TEI header with further categories and also to explore the possibilities for migration of legacy data in a wide range of formats into a TEI-conformant XML format.

    Big Data inom den svenska sjukvården: En studie om framtida hinder och möjligheter2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studie har genomförts med syftet att redogöra för vilka möjligheter och hinder som kan uppstå vid införandet av Big Data-baserade IT-lösningar inom den svenska hälso- och sjukvården. Studien bygger på en explorativ fallstudie med fokus på det svenska projektet 3R- Framtidens vårdinformation. Intervjuer har genomförts med personer som är insatta och kunniga i ämnet och därför kunnat bidra med en sammanfattad bild av vilka initiativ och ambitioner som finns i dagsläget. Studiens resultat visar att Big Data kan bidra med en mängd möjligheter till förbättrad sjukvård i Sverige. Resultatet visar på att möjligheten med att samla all information i en gemensam kärna, bidrar till bland annat förbättrad forskning, en förbättrad relation mellan vårdgivare och patienter, möjlighet att kunna utföra prediktiva analyser samt underlättar arbetet med diagnostisering av sjukdomar. Utöver det har en rad olika hinder och utmaningar konstaterats till exempel miljömässiga, organisatoriska, projektrelaterade och tekniska.

    Ill-structured Problem Solving in Engineering Education2007In: IEEE Frontiers in Education conference, 2007, p. F3F1-F3F2Conference paper (Refereed)
    Abstract [en]

    There is a gap between the problems our students typically encounter in their education and the problems they are likely to be asked to solve in their future employments. It is convenient in education, both in specification and assessment, to provide fairly well-structured problems, and many instructors view using such problems as a way to manage the learning process. However, real-world problems are typically ill-structured and we argue that using only well-structured problems as learning examples does not prepare our students for the problems they will encounter in their professional life. Preparing students for dealing with ill-structured, or open ended, problems is an educational challenge involving critical thinking skills, which most instructors and curriculum designers view as an important goal of the learning process. This panel is designed to address issues of open or ill-structured problems from learning aspects. The panel will also cover concrete examples to inspire education designers preparing students for their future careers by improving their problem solving capabilities through use of ill-structured problems as learning examples.

    Balancing Scaffolding and Complexity in Open Ended Group Projects (OEGPs): A Learning Theory View2007In: IEEE Frontiers in Education conference, 2007, p. F2G1-F2G2Conference paper (Refereed)
    Abstract [en]

    There is a gap between the problems our students typically encounter in their education and the problems they are likely to be asked to solve in their future employments. It is convenient, both in terms of specification and assessment, in education to provide fairly well-structured problems, and many instructors view using such problems as a way to control what the students learn. Typical real-world problems are however ill-structured and we argue that working on well-structured problems does not prepare our students for the problems they will encounter in their professional life. Preparing our students for dealing with ill-structured, or open ended, problems is an educational challenge involving critical thinking skills, which most instructors and curriculum designers view as an important goal. This paper will focus on the use of Open Ended Group projects as an educational setting and address why it can be useful in reaching general goals of engineering education and how balanced scaffolding can help reaching those goals. The paper will also cover a concrete example to inspire education designers to better prepare our students for their future careers by improving their problem solving capabilities.

    Trådlösa Nätverk: säkerhet och GPU2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Wireless networks are inherently vulnerable for eavesdropping since they use radio waves to communicate. Wireless networks are therefore protected by encryption. WEP was the first encryption standard that was widely used. Unfortunately WEP proved to have several serious vulnerabilities. WEP could be circumvented within few minutes. Therefore WPA was developed as a response to the weak WEP. Shortly thereafter WPA2 was released and are now being used in present. The only weakness with WPA2 is in the subset WPA2-PSK when weak passwords are being used. Software could easily go through large dictionaries to verify if a password could be recovered. But that is time consuming and therefore providing wireless networks limited protection. However a new area of use with advanced graphic cards has showed that it is providing a faster way of recovering passwords than the ordinary processor on the motherboard. That opens up for the larger use of dictionaries and the processing of words or combinations of words. That is what this study aims to shed light on. How the efficiency of the graphic cards have affected security in wireless networks from a corporate perspective of view.

    "Got Skills...?": En kvalitativ studie om kompetensutveckling baserat på StarCraft II2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The use of computer games has grown exponentially in the past few years and StarCraft II is one of the most popular e-sports today, played by millions of people worldwide. This study investigates the game’s effect on skills, as perceived by the players of StarCraft II.

    The study was conducted by using an empirical survey and interviews. The skills being investigated were both physical and mental in their nature. The conclusion was that the majority of players perceived that their skills regarding reaction speed, multitasking, APM, analysis and strategy were increased the most, while there was a smaller change in social skills and language skills. Additionally, people who played team games of StarCraft II did, however, feel that their teamwork, conflict management and leadership capabilities increased.
