    A Simulation Framework for Efficient Search in P2P Networks with 8-Point HyperCircles2008Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This report concerns the implementation of a simulation framework to evaluate an emerging peer-to-peer network topology scheme using 8-point hypercircles, entitled HyperCircle. This topology was proposed in order to alleviate some of the drawbacks of current P2P systems evolving in an uncontrolled manner, such as scalability issues, network overload and long search times. The framework is supposed to be used to evaluate the advantages of this new topology. The framework has been built on top of an existing simulator software solution, the selection of which was an important part of the development. Weighing different variables such as scalability and API usability, the selection fell on OverSim, an open-source discreet-event simulator based on OMNET++.

    After formalizing the protocol for easier implementation, as well as extending it for better performance, implementation followed using C++ with OverSim’s API and simulation library. Implemented as a module (alongside other stock modules providing their own protocols such as Chord and Kademlia), it can be used in OverSim to simulate a user-defined network using one of the simulation routine applications provided (or using a custom application written by the user). For the purposes of this thesis, the standard application KBRTestApp was used; an application sending test messages between randomly selected nodes, while adding and removing nodes at specific time intervals. The adding and removing of nodes can be configured with probability parameters.

    Tentative testing shows that this implementation of the HyperCircle protocol has a certain performance gain over the OverSim implementations of the Chord and Kademlia protocols, measurable in the time it takes a message to get from sender to recipient. Further testing is outside the scope of this thesis.

    The impact of a real-time IT-Logistics solution: Implementation effects and consequences2005Independent thesis Advanced level (degree of Magister), 10 points / 15 hpStudent thesis
    Abstract [en]

    Today’s business market is highly competitive, therefore companies need to be constantly updated and change the way they operate their business, in order to survive and remain competitive. The situation on today’s market requires that companies have the ability to quickly respond to market changes and new customer demands within short product lifecycles. In order to deal with this new market situation, companies need to improve the integration with other companies within their business. This integration facilitates the companies’ ability to quickly adapt to new market situations and survive on a fast changing market. One of the main underlying concepts of this collaborative commerce is Supply Chain Management (SCM) which integrates and coordinates a company’s processes both internally and externally. Information Technology (IT) could improve the effectiveness of SCM. IT-solutions make the business processes more effective and improves the integration with other actors within the supply chain. The purpose with this thesis is to describe and explain the effects for businesses and the consequences for its processes when implementing a real-time IT-Logistics solution together with identifying the critical success factors. The thesis has been conducted by studying theory regarding supply chain management, business renewal and implementation effects. Further, a case study has been conducted where three actors have been interviewed; a manufacturer (Volvo Powertrain), a subcontractor (Metallfabriken Ljunghäll AB) and a system developer (PipeChain). The analysis of the theoretical framework and the empirical research has contributed with an identification of major effects and consequences when implementing a real-time IT-Logistics solution. Some of the effects are: inventory reduction, higher delivery accuracy, improved relations and increased flexibility. Examples of consequences these effects have caused are: more accurate planning and production, effective production processes as well as an improved delivery process. Additionally, success factors for an implementation have been identified such as mutual trust, understanding of change and evaluation.

    Outlier Detection for Video Session Data Using Sequential Pattern Mining2018In: ACM SIGKDD Workshop On Outlier Detection De-constructed, 2018Conference paper (Refereed)
    Abstract [en]

    The growth of Internet video and over-the-top transmission techniqueshas enabled online video service providers to deliver highquality video content to viewers. To maintain and improve thequality of experience, video providers need to detect unexpectedissues that can highly affect the viewers’ experience. This requiresanalyzing massive amounts of video session data in order to findunexpected sequences of events. In this paper we combine sequentialpattern mining and clustering to discover such event sequences.The proposed approach applies sequential pattern mining to findfrequent patterns by considering contextual and collective outliers.In order to distinguish between the normal and abnormal behaviorof the system, we initially identify the most frequent patterns. Thena clustering algorithm is applied on the most frequent patterns.The generated clustering model together with Silhouette Index areused for further analysis of less frequent patterns and detectionof potential outliers. Our results show that the proposed approachcan detect outliers at the system level.

    A Minimum Spanning Tree Clustering Approach for Outlier Detection in Event Sequences2018In: The 17th IEEE International Conference on Machine Learning and Applications Special Session on Machine Learning Algorithms, Systems and Applications, IEEE, 2018Conference paper (Refereed)
    Abstract [en]

    Outlier detection has been studied in many domains. Outliers arise due to different reasons such as mechanical issues, fraudulent behavior, and human error. In this paper, we propose an unsupervised approach for outlier detection in a sequence dataset. The proposed approach combines sequential pattern mining, cluster analysis, and a minimum spanning tree algorithm in order to identify clusters of outliers. Initially, the sequential pattern mining is used to extract frequent sequential patterns. Next, the extracted patterns are clustered into groups of similar patterns. Finally, the minimum spanning tree algorithm is used to find groups of outliers. The proposed approach has been evaluated on two different real datasets, i.e., smart meter data and video session data. The obtained results have shown that our approach can be applied to narrow down the space of events to a set of potential outliers and facilitate domain experts in further analysis and identification of system level issues.

    Development of Web-based Health Care Services in Swedish County Councils: Strategies, Usage and Challenges2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    eHealth has been adopted by many countries across the globe in response to cut down cost and improve the quality of life. Sweden has been engaged in providing web-based health care services for its citizens for the past decade and county councils have the responsibility to develop them. The main aim of this thesis is to present answers to the following research questions:What strategies (formal and informal) guide the development of web-based health care services provided by the Swedish county councils?What barriers exist in relation to the development and usage of web-based health care services provided by the county councils from the viewpoint of their IT leaders?From the perspective of IT leaders in the county councils and in their capacity to develop, manage and monitor their organizations‘ website content, which web-based health care services are mostly accessed by users and what age group utilize the services most?The thesis is an exploratory research conducted through a survey based on a mail questionnaire that was posted to all 21 county councils in Sweden with 18 councils responding. The results show that all county councils have formally adopted the National eHealth Strategy to guide the development of web-based health care services and some have other informal strategies as well. Technological barriers, resistance to use the web-based services and changing business process to integrate ICTs have been identified by IT leaders as major challenges that impede the development of web-based health care services in Swedish county councils. Swedish citizens more frequently access prescription renewal and booking and cancellation of appointments than other available web-based health care services which depicts a trend towards the use of advanced interactive services than basic information seeking, and people in the ages of 46 to 55 have been identified as the frequent users of web-based health care services according to IT leaders from the county councils.

    Business models for telemedicine services: A literature review2015In: Health Systems, ISSN 2047-6965, E-ISSN 2047-6973, Vol. 4, no 3, p. 189-203Article in journal (Refereed)
    Abstract [en]

    Telemedicine has been acknowledged to improve the quality of healthcare. However, many telemedicine services fail beyond the pilot phase. A literature review on business model components for telemedicine services was conducted. Based on specified inclusion criteria, 22 publications were included in the review. To facilitate the analysis of literature, a business model framework with value as its central focus was proposed. Improvement in quality, efficiency and accessibility of care were identified to be the outcomes of telemedicine, with patients and healthcare personnel being the main users of the services, which are delivered through home, institutional and community-based care. Patients, health providers, vendors, payers and government agencies are actors involved in the delivery of telemedicine services, which require investments in resources like videoconferencing technologies, home monitoring devices and other IT infrastructure. Subscriptions, reimbursements and pay-per-use revenue streams were identified as feasible for commercializing telemedicine services.

    Effects of a Home-based Monitoring Device on Innovation in Healthcare Delivery: A Pilot Study2013In: Information Systems and Technology for Organizations in a Networked Society / [ed] Tomayess Issa, Pedro Isaias and Piet Kommers, Hershey, PA, USA: IGI Global, 2013, p. 316-334Chapter in book (Refereed)
    Abstract [en]

    Information technology has been suggested to improve patient health outcomes and reduce the burden of care. In this study, we explored the effects of collaborative innovation between caregivers and patients on healthcare delivery as a consequence of the use of an IT-based device by patients with atrial fibrillation. Two cardiologists and two nurses were interviewed while questionnaires were mailed to 75 patients querying them about the use of a home-based ECG for remote monitoring. Findings indicated that the caregivers considered the device to enhance the quality of clinical decision-making. Patients found the device to be useful and felt more involved in their own care. However, the introduction of the device presented work overload for the caregivers. Thus, the facilitation of timely diagnostics and decision-making were not realized. IT is an enabler through which innovation in healthcare delivery can be realized, but it must be integrated into work practices to realize potential benefits.

    Knowledge management cloud-based solutions in small enterprises2015Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    Purpose – The aim of this study is to determine if adopting cloud-based knowledge management is a viable way forward for small enterprises and to investigate what are the main factors that might facilitate or inhibit these companies to adopt such solutions.Design/Methodology/Approach - In order to understand the main factors that could influence the adoption of a cloud-based knowledge management solution in small enterprises, I used a qualitative research approach, based on four semi-structured interviews with four small companies from Romania.Findings – The results of the study suggest that implementing knowledge management in the cloud is particularly beneficial for small enterprises, as a lower investment in IT infra-structure can create a competitive advantage and help them implement knowledge man-agement activities as a strategic resource. Moreover, the study suggests that relative ad-vantage, compatibility and technology readiness will influence companies in moving their knowledge to the cloud. Also, the study reveals that companies which did not adopt such a solution had already established systems for managing knowledge and failed to realize its benefits, it was not perceived as needed, they had a low level of awareness or cited security and uncertainty reasons.

    Balancing walled garden and open platform approaches for the Internet of Things: A case study of Husqvarna Group2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The term “Internet of Things” (IoT) was first introduced by a technology pioneer Kevin Ashton in 1999.Although the term is relatively new, the idea of making networks and computers communicate in order totrack and manage devices has been around for many years. As of now IoT is a rising topic in technicalcommunity. Some specialists are anticipating that by 2025 there will be around 100 billion connected IoTdevices with a worldwide economic impact of more than $11 trillion. On the other hand, Internet of Thingsemerges significant challenges. Currently the organization around world use two main approaches whenentering the IoT market. First one is an open platform and is represented by interoperability andcollaboration with devices from different vendors. Second one is a closed platform, or a “walled garden”approach. A “walled garden” approach is characterized by building “fences” around the user. In other words,the service provider has control over applications, content and media and also restricts the non-approvedcontent to reach the customer. Therefore, the research set out to explore these approaches and show thebenefits and limits they can have on an organization. The research was conducted in collaboration with aSwedish manufacturer of outdoor power products called Husqvarna Group. In order to fully acknowledgethe organization’s approach, 4 interviews were conducted with managers, back end developers andconsultants hired by Husqvarna Group. From the findings, some things should be taken in consideration.First, IoT involves big data being collected, therefore security and privacy are crucial when developingdevices and systems. Second, it is essential for an organization to have the same views when taking a newdirection. Third, when discussing Internet of Things, it means that things connect, devices to sensors,sensor to gateways and gateways to system. And there shouldn’t be a delimitation from a vendor to another.Therefore, open platform approach is seen as the way to diversity and innovation.

    Customer Maturity Analysis Tool: A case study in designing a Customer MaturityAnalysis Tool2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The IT consultancy industry is characterized by knowledge intensive implementationprojects related to varying levels of standardized information system software. When faced with a large implementation project at a previously unknown customer various assessmentsis usually conducted to identify the level of fit between the software and organizationin order to plan and structure the implementation process. However, there are several aspects of the customer organization that potentially can affect the end result as well as the implementation process that is unrelated to the fit between the software and the implementation organization as well as the potency of the implementation method. By conducting measurements of these maturity factors within the customer organization the implementing procedure can be modified based on the customer maturity level in order to become more aligned with the capabilities present in the customer organization.

    Research question: Which aspects need to be covered by a Customer Maturity Analysis Tool (CMAT) in order to evaluate the pre implementation maturity for potential customersof our case company and how should these aspects be organized and measured? The first task of the research process was to create an underlying model of maturity perspectives and aspects to structure the literature review as well as the empirical data collection. It was decided to adhere to a deductive approach where the theoretical model would be validated and if necessary modified in accordance to feedback from potential users of the CMAT within the case company. This procedure was repeated in the creation of measurements and maturity levels for the aspects to be used in the tool. The research process would therefore transition from a general model based on literature review, through a iterative feedback loop to a final model tailored to the specific requirementsof the case company. The final CMAT ended up containing four main perspectives of customer maturity; ITi nfrastructure, Culture, Process and Business Governance. These four perspectives were in turn divided into subgroups in order to be able to aggregate and compare differentaspects of the perspectives with each other.

    Using conformal prediction to prioritize compound synthesis in drug discovery2017In: Proceedings of Machine Learning Research: Volume 60: Conformal and Probabilistic Prediction and Applications, 13-16 June 2017, Stockholm, Sweden / [ed] Alex Gammerman, Vladimir Vovk, Zhiyuan Luo, and Harris Papadopoulos, Machine Learning Research , 2017, p. 174-184Conference paper (Refereed)
    Abstract [en]

    The choice of how much money and resources to spend to understand certain problems is of high interest in many areas. This work illustrates how computational models can be more tightly coupled with experiments to generate decision data at lower cost without reducing the quality of the decision. Several different strategies are explored to illustrate the trade off between lowering costs and quality in decisions.

    AUC is used as a performance metric and the number of objects that can be learnt from is constrained. Some of the strategies described reach AUC values over 0.9 and outperforms strategies that are more random. The strategies that use conformal predictor p-values show varying results, although some are top performing.

    The application studied is taken from the drug discovery process. In the early stages of this process compounds, that potentially could become marketed drugs, are being routinely tested in experimental assays to understand the distribution and interactions in humans.

    Exploring the governance of IT in SMEs in Småland2012Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    With many research available on IT governance, this research differs from most of them due to its delimitation. The focus of this research lies in the two domains of value creation and performance measurement. Furthermore, the area of research has been small and medium Enterprises located in the area of Småland, Sweden.

    Brisebois, Boyd & Shadid (2001) gave us the following definition of IT governance: “How those persons entrusted with governance of an entity will consider IT in their supervision, monitoring, control, and direction of the entity. How IT is applied will have an immense impact on whether the entity will attain its vision, mission, or strategic goal.”

    An objective of IT governance is to align the IT resources of an enterprise in a way that it fast-tracks the business priorities of the enterprise and assures that the investments in IT generates business value and that the IT is performing to its expectations.

    The research questions and the outcome of this research paper sheds light on the challenges of both value creation and performance measurement within the SMEs, but it also showcases what the driving forces of IT value creation are and which benefits arise from measuring the IT performance within the SMEs.

    Through semi-structured interviews with four SMEs, based in the region of Småland, numerous amounts of challenges and driving forces for IT value creation and challenges and benefits to measuring IT performance have been extracted.

    Based on the extracted information from the interviews, an analysis and a conclusion have been formed by the authors. In the end, the authors provide their thoughts for suggestions for further work and how all of this contributes to the field of Informatics.

    Exploring the Integration of Enterprise Systems Solutions Within A Supply Chian2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Over the decades, as organizations begin to move globally there has been a sporadic flow of information in their supply chain. Competition today is forcing companies to integrate tightly with their suppliers and customers, in order to reduce the time available to flex the supply chain (SC) (Koh S.C, Saad S, Arunachalam S, 2006). The integration of firms and departments and information is getting more and more complicated. Regardless of enterprise system solutions being introduced as “integrated suites” they have failed to accomplish application and supply chain integration (Themistocleous, M. Irani, Z. O‟Keefe, and R. 2001). Therefore, this thesis aims to explore, gain better understanding and to explain the balance that may occur between the challenges and benefits gained from integrating enterprise resource planning and supply chain management.Our topic of interest could be view from both developers and user perspective. Developer/consultant‟s perspective is based on the viewpoint of those involved in and responsible for developing enterprise solutions. User‟s perspective, this perspective gives insight to how the integration process is perceived by organisations actually using the solutions. We chose the User perspective because we consider the user to be the direct beneficiary of whatever outcome is gotten from both the business solutions and its integration.In order to achieve a purposeful thesis. We decided to use an interpretive perspective which focus on exploring and gaining insight into issues of integrating enterprise system solution. We used both the inductive and the deductive approaches in our research. This would be advantageous due to the nature of our research topic, as there is little existing knowledge about the integration of enterprise systems solution within supply chain and there are lots of literatures related to the enterprise system solutions (ERP and SCM) been observed. The inductive approach would guide us to choose one or a few specific interactions to explore in-depth, while the deductive approach would aid us when making an hypothesis, since we would be collecting ideas about previous research and theories in order to guide us and make comparison.Conclusively, we found that the balance between challenges and benefits of ERP and SCM are unequivocal, as the benefits surpass the challenges and the effect of challenges on organisation‟s benefit is that it prolongs the short term benefit.

    Improving Researcher-Patient Collaboration through Social Network Websites2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The main purpose of this study/thesis is to, through an interview with researchers in medical field in Jönköping,  provide an empirical analysis of the link or relationship between medical researcher and patient through social networking sites specifically for collaboration in order to improve relationships, dissemination of information and knowledge sharing.

    Background: The importance of social networking websites as a means of interaction between groups of individuals cannot be underestimated. Their impact on daily life activities and activities cannot be underestimated. Because  millions of individuals are making use of Social Network Sites (SNSs) to build or reinforce relationships, connect, disseminate and share information as well as sharing of knowledge whether personal or non-personal experiences with people they already know offline or new people online. Therefore, the authors are interested basically in how social networking web sites are being utilized in terms of collaborations, information and knowledge sharing and particularly in what benefits and challenge are connected to improving inter-groups collaboration in research study between researchers and ordinary citizens.

    Method: A review of literature gives us insight about the subject terms, critical and sensitive issues in regards to collaboration through social networking sites designed for research purpose. We apply in general networking theories such as social capital and two of its components couple with Putman´s theory of bonding and bridging social capital as a theoretical framework to synthesize the concept of  ties (strong or weak) . Our analysis based on the empirical data gathered through surveys, interviews and observation provide us with interesting preliminary results and with blueprints to guide the analysis of the thesis.

    Conclusion: Social networking platforms are valuable and useful in our generation being part of daily life and activity to keep up with people within our networks. However, the authors discovered that the advantages of involving ordinary citizens to participate in improving researcher-patient collaboration through dynamic social networking actually outweigh the disadvantages despite all odds and sensitive issues such as trust, privacy issues and sceptics of some researchers. In others words, some of the researchers were enthusiastic to collaborate in terms of disseminating useful information and sharing valuable knowledge with ordinary citizens. Overall, the study revealed positive result that despite weak ties relationships, the willingness to collaborate is far more than the obstacles perceived in the course of establishing such collaboration.

    Abstract [en]

    People with disabilities constitute a big group of Internet users. Due to great advances in adaptive technology for people with disabilities more and more disabled will have access to Internet. For that reason it is extremely important for a web developer to be aware of different disabilities that complicate or prevent using Internet, different adaptive technologies that facilitate using Internet and different methods, both in design and programming, that make Internet accessible for people with disabilities.

    In this report we have dealt with three problems:

    • Which types of disabilities that complicate or prevent using Internet?

    • Which types of adaptive technologies are available concerning using Internet?

    • How can a web developer or programmer increase the accessibility to Internet for people with disabilities?To investigate how disabled people use adaptive technologies and which difficulties they experience when using Internet we have interviewed people with various types of disabilities.

    Application patterns for ontology based applications2006Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    Software patterns have been proven as a valuable way to storing a repeatable solution to a commonly occurring problem in software design. A pattern is not a finished design that can be directly formed into program code; instead it is a description how to solve a problem that may occur in many situations.

    In the ontology community very little research have been made in producing high-level patterns where the solution shows how an architecture of an ontology based software might look like.

    In this thesis the results of examining how high-level patterns of this type relates to other types of patterns are given and how these patterns would be described are formulated.

    Describing Ontology Applications2007In: Proceedings of the 4th Annual European Semantic Web Conference (ESWC 2007), 2007Conference paper (Refereed)
    Abstract [en]

    Semantic Web technologies are finally, after a few years of infancy, truly entering the business world to support the growing needs of computer aided information selection and processing. There are already quite well-defined development processes and methods in the software engineering field to handle the construction of large scale and complex enterprise systems, and to reuse knowledge in different software domains patterns are considered to be common practise. Patterns can be described on different levels of abstraction, but the patterns in the focus of this paper are on the software architecture level. In this paper we present a definition of the notion ”ontology application pattern”, as a special form of software architecture patterns describing an ontology-based system. We also show how such patterns, as well as the description of the pattern instantiations, can be described using a modified architecture description language.

    Riktlinjer för grafiska användargränssnitt för lagersystem2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna rapport är att undersöka och sammanställa riktlinjer för att utveckla ett grafiskt användargränssnitt för ett lagersystem. För att uppnå syftet med rapporten litteraturstudier, intervjuer, observationer och en prototyputveckling utfördes. Utifrån litteraturstudier visade det sig att det inte fanns specifika designriktlinjer för utveckling av lagersystem fast det fanns allmänna riktlinjer som kan användas för design av olika system. Intervjuer med utvecklare och en utvecklingschef på företaget Qsys hjälpte till att hitta befintliga riktlinjer som företaget använder. Det visade sig att de använder allmänna riktlinjer som inte är specifika för lagersystem. För att hitta mer specifika riktlinjer observerade vi några lagerarbetare för att bättre förstå hur de integrerar med det befintliga systemet som de använder. Utifrån analysen av observationerna, upptäcktes det nya riktlinjer. Med hjälp av de allmänna riktlinjer som hittades i litteraturen och riktlinjer som upptäckes efter analysen av observationer, utvecklade vi en prototyp som sedan testades. Resultatet vi fick utifrån analysen av intervjuerna med lagerarbetarna efter prototyptestning, hjälpte med att hitta ytterligare specifika riktlinjer.För att utveckla ett användarvänligt lagersystem, behöver man ett användarvänligt gränssnitt. I denna rapport presenterar vi några riktlinjer som man kan använda sig av för att utveckla ett användarvänligt gränssnitt för lagersystem.

    Ontology-Based Model For The "Ward-round" Process in Healthcare (OMWRP)2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Abstract

    In the current arena, rapid changes are required to address dynamic patient’s treatment process needs according to the patient’s demand in the healthcare sector. This research work addresses existing problems about information flow in ward-round, what is the optimal information need for an individual with his/her competences according to their role during ward-round in healthcare area. This work also mentions what are the certain activities which are required during the patient treatment.

     

    This research work contributes in the field of Information logistics and ontology development in healthcare. So the main purpose of this thesis is to design an ontology based model that can fix information flow problems in the ward-round process of hospital unit. The ontology based model can be used to provide relevant information to the domain users according to their needs and demands. The ontology based model projects domain users profiling and describes their roles, information demands with competencies: skills, qualifications and experiences. The ontology based model will be implemented in OWL language that can be used in an application to support ward-round activities for achieving effective patient’s treatment process.  

     

    For ontology development is concerned, different ontology development methodologies have been reviewed from literature review by the author to analyze the existing problems in the ward-round. This thesis incorporates Hybrid Methodology (HM) that helps to develop ontology based model that addresses information flow problems in ward-round. The proposed ontology based model is developed in web Ontology Language (OWL) supported tool protégé 4.0.2 that can be considered as foundation to develop a software product with the help of IT practitioners and developers to fulfill medical practitioner’s demands in ward-round’s context.

    Modelling of the Ward Round Process in a Healthcare Unit2011In: The Practice of Enterprise Modeling: 4th IFIP WG 8.1 Working Conference, PoEM 2011 Oslo, Norway, November 2-3, 2011 Proceedings / [ed] Paul Johannesson, John Krogstie and Andreas L. Opdahl, Springer Berlin/Heidelberg, 2011, Vol. 92, p. 223-237Conference paper (Refereed)
    Abstract [en]

    Information systems (IS) are nowadays extensively used to support all kinds of activities in healthcare organisations. Enterprise modelling can help to make the use of IS in healthcare more effective by providing process and domain models reflecting a particular healthcare unit. This paper proposes a model of the ward round process in a healthcare unit. The proposed model identifies the roles of medical professionals, tasks that can be performed according to the personnel’s competences, and activities that are carried out as part of the tasks to achieve goals of the ward round process. A formal approach has been used to implement the modelling results in the form of an ontology. Such formal ontologies can support improvement and development of IS in healthcare. We learned that modelling workshops are important for development of models that can be formalized in a machine-readable form.

    SmartEnv as a Network of Ontology Patterns2018In: Semantic Web, ISSN 1570-0844, E-ISSN 2210-4968, Vol. 9, no 6, p. 903-918Article in journal (Refereed)
    Abstract [en]

    In this article we outline the details of an ontology, called SmartEnv, proposed as a representational model to assist the development process of smart (i.e., sensorized) environments. The SmartEnv ontology is described in terms of its modules representing different aspects including physical and conceptual aspects of a smart environment. We propose the use of the Ontology Design Pattern (ODP) paradigm in order to modularize our proposed solution, while at the same time avoiding strong dependencies between the modules in order to manage the representational complexity of the ontology. The ODP paradigm and related methodologies enable incremental construction of ontologies by first creating and then linking small modules. Most modules (patterns) of the SmartEnv ontology are inspired by, and aligned with, the Semantic Sensor Network (SSN) ontology, however with extra interlinks to provide further precision and cover more representational aspects. The result is a network of 8 ontology patterns together forming a generic representation for a smart environment. The patterns have been submitted to the ODP portal and are available on-line at stable URIs.

    User-oriented Assessment of Classification Model Understandability2011Conference paper (Refereed)
    Abstract [en]

    This paper reviews methods for evaluating and analyzing the understandability of classification models in the context of data mining. The motivation for this study is the fact that the majority of previous work has focused on increasing the accuracy of models, ignoring user-oriented properties such as comprehensibility and understandability. Approaches for analyzing the understandability of data mining models have been discussed on two different levels: one is regarding the type of the models’ presentation and the other is considering the structure of the models. In this study, we present a summary of existing assumptions regarding both approaches followed by an empirical work to examine the understandability from the user’s point of view through a survey. The results indicate that decision tree models are more understandable than rule-based models. Using the survey results regarding understandability of a number of models in conjunction with quantitative measurements of the complexity of the models, we are able to establish correlation between complexity and understandability of the models.

    Making the Web more Pragmatic: Exploring the Potential of some Pragmatic Concepts for IS Research and Development2008In: The Inaugural meeting of The AIS Special Interest Group on Pragmatist IS Research (SIGPrag 2008) at International Conference on Information Systems (ICIS2008), France, The AIS Special Interest Group on Pragmatist IS Research (SIGPrag 2008) – www.sigprag.org , 2008, p. 67-72Conference paper (Other academic)
    Abstract [en]

    In this paper we examine some pragmatic concepts that we believe have a potential in relation to three core activities of the IS-field; 1) description and understanding, 2) evaluation, and 3) design. The concepts that we will examine are “social activity”, “communicative act”, “sequences of communicative acts” or “exchange types”, “communicative feedback” and “turn management”. We describe the concepts and then exemplify how they can be used to analyze web services by examining e-mail and Wikipedia as two activities currently on the web. Our analysis leads to a  partly new description of both phenomena. It also leads to a number of open questions concerning the functionalities of both phenomena.

    Att säkerställa kvalitet i den service som en kommun erbjuder sina medborgare är en komplicerad uppgift. Olika analysinstrument och arbetsformer behöver tillämpas för att säkerställa tillräckligt tydligt medborgarfokus. I detta arbete har en metod utvecklats för att analysera kvalitet i det elektroniska servicemötet. Denna metod bygger på att betrakta organisationens ambitioner och de instrument som tillhandahålls för medborgarna i kontrast till den livssituation som medborgaren befinner sig i. Olika analysinstrument har tillämpats där resultaten pekar på att de tjänster som Marks kommun idag tillhandahåller för elektronisk kontakt inte i tillräckligt grad motsvarar medborgarnas förväntningar. I och med att arbetet i detta inledningsskede bara fokuserat på den elektroniska kontakten så är nästa steg att 1) bredda analysen till att också innefatta övriga sätt att ha kontakt med medborgaren och 2) studera samspelet mellan olika kontaktsätt samt 3) analysera processer och intern koordination hos Marks kommun för att säkerställa kvalitet i kontaktverksamheten.

    The Influence of ERP Simulations on ERP Systems Implementation2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Companies are always trying to enhance their functioning to achieve a competitive advantage in a given market. Some of the tools that are used to improve organizational functioning include ERP systems. In fact, ERP systems are becoming very popular among firms, to the point where they are considered by some as an ailing business savior. Nevertheless, despite the attractive functions that an ERP system may display to an interested company, implementing such a system successfully is a task that is far from being easy. Several problems may arise in the implementation phase, and a failure to address them correctly can have terrible consequences on the general functioning of a firm. Two of the main factors that contribute to a failed ERP system implementation are training and resistance to change. A tool that may actually help with the ERP system implementation failure is ERP simulation.

    The main purpose of this thesis is to study the potential effect that ERP simulations can have on a potential ERP system user skills and knowledge, and thereafter find the potential impact that they may have while being used during an ERP implementation to facilitate training and reduce resistance to change.

    The tools that were used to successfully accomplish this research were a personal interview with an ERP simulation expert, a detailed survey with ERP simulation participants, and various information that were collected from books, articles, reports and websites.

    This thesis main results show that ERP simulations can enable ERP users to improve their knowledge of ERP systems effectively, and also have potential to contribute during the implementation phase by reducing the possible problems that may arise from the training and the resistance to    change perspectives.

    Cloud Computing: Security Risks, SLA, and Trust2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    With Cloud Computing becoming a popular term on the Information Technology (IT) market, security and accountability has become important issues to highlight. In our research we review these concepts by focusing on security risks with Cloud Computing and the associated services; Software, Platform and Infrastructure (SPI) and connecting them with a social study of trust.

    The method that was conducted during our research was reviewing secondary literature, interviewing different experts regarding Cloud Computing and relating standards already established by ENISA, NIST, and CSA to the interviews.

    The result of this study shows connections between the specific SPIs, both how they compare, but also how they differ. In the end we were also able to rank the top security risks from interviews with experts and see which SPI could be the most insecure one and  what countermeasures could be applied.

    This was further related to trust and Service Level Agreement (SLA) in Cloud Computing to show how the security risks we discuss are related to these two specific areas. By highlighting this we wanted to present useable information for both clients and providers in how to create a better Cloud Computing environment.

    Studie utav ett larmsystem ur ett signalteoretiskt perspektiv: Study of a detector by a signal detection theory2006Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    In present-day situation many libraries use detectors so that they can be able to prevent attempts too take out books without registering them. The university library in Jonkoping is one of the libraries that have such a detector. But unfortunately it doesn’t always work correct and can also react on other things a part from books. This is a big problem since the library staff don’t have time to check all signals that comes from detector. This paper will focus to help the university library in Jonkoping to identify the causes of the false alarms.

    This paper have the purpose to help library staff to decrease the false alarms so they can be able to get more time over to examine the essential signals from the detector. To be able to identify the causes of the false alarms two experiments was implemented. 180 persons participated, they were divided into three subgroups. In the other experiment 400 persons participated, of whom 200 was female and 200 male. Astonishing to see was that the outcome of the experiments showed that the cause of the false alarms wasn’t the detector, instead the results showed that it was two other factors that affected the detector. One factor was the books that were send from other libraries in Sweden, they hadn’t been unimagnetised and the other reason was the self-service machine.

    In the conclusion and discussion two simple recommendations have been given to help the personnel:

    • To inform all other libraries that send books about the problems that the university library in Jonkoping has with books that aren’t unimagnetised. In this way they will be more careful before they send away the books.

    • To write a note with information about the self-service machine so that the students learn how to use this service.

    These simple recommendations will help the library to decrease the false alarm.

    Metamodel based multi-objective optimization2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    As a result of the increase in accessibility of computational resources and the increase in the power of the computers during the last two decades, designers are able to create computer models to simulate the behavior of a complex products. To address global competitiveness, companies are forced to optimize their designs and products. Optimizing the design needs several runs of computationally expensive simulation models. Therefore, using metamodels as an efficient and sufficiently accurate approximate of the simulation model is necessary. Radial basis functions (RBF) is one of the several metamodeling methods that can be found in the literature.

    The established approach is to add a bias to RBF in order to obtain a robust performance. The a posteriori bias is considered to be unknown at the beginning and it is defined by imposing extra orthogonality constraints. In this thesis, a new approach in constructing RBF with the bias to be set a priori by using the normal equation is proposed. The performance of the suggested approach is compared to the classic RBF with a posteriori bias. Another comprehensive comparison study by including several modeling criteria, such as problem dimension, sampling technique and size of samples is conducted. The studies demonstrate that the suggested approach with a priori bias is in general as good as the performance of RBF with a posteriori bias. Using the a priori RBF, it is clear that the global response is modeled with the bias and that the details are captured with radial basis functions.

    Multi-objective optimization and the approaches used in solving such problems are briefly described in this thesis. One of the methods that proved to be efficient in solving multi-objective optimization problems (MOOP) is the strength Pareto evolutionary algorithm (SPEA2). Multi-objective optimization of a disc brake system of a heavy truck by using SPEA2 and RBF with a priori bias is performed. As a result, the possibility to reduce the weight of the system without extensive compromise in other objectives is found.

    Multi-objective optimization of material model parameters of an adhesive layer with the aim of improving the results of a previous study is implemented. The result of the original study is improved and a clear insight into the nature of the problem is revealed.

    Multi-objective optimization of material model parameters of an adhesive layer by using SPEA22015In: Advances in structural and multidisciplinary optimization: Proceedings of the 11th World Congress of Structural and Multidisciplinary Optimization (WCSMO-11) / [ed] Qing Li, Grant P Steven, Zhongpu (Leo) Zhang, The International Society for Structural and Multidisciplinary Optimization (ISSMO) , 2015, p. 249-254Conference paper (Refereed)
    Abstract [en]

    The usage of multi material structures in industry, especially in the automotive industry are increasing. To overcome the difficulties in joining these structures, adhesives have several benefits over traditional joining methods. Therefore, accurate simulations of the entire process of fracture including the adhesive layer is crucial. In this paper, material parameters of a previously developed meso mechanical finite element (FE) model of a thin adhesive layer are optimized using the Strength Pareto Evolutionary Algorithm (SPEA2). Objective functions are defined as the error between experimental data and simulation data. The experimental data is provided by previously performed experiments where an adhesive layer was loaded in monotonically increasing peel and shear. Two objective functions are dependent on 9 model parameters (decision variables) in total and are evaluated by running two FEsimulations, one is loading the adhesive layer in peel and the other in shear. The original study converted the two objective functions into one function that resulted in one optimal solution. In this study, however, a Pareto frontis obtained by employing the SPEA2 algorithm. Thus, more insight into the material model, objective functions, optimal solutions and decision space is acquired using the Pareto front. We compare the results and show good agreement with the experimental data.

    Radial basis functions as surrogate models with a priori bias in comparison with a posteriori bias2017In: Structural and multidisciplinary optimization (Print), ISSN 1615-147X, E-ISSN 1615-1488, Vol. 55, no 4, p. 1453-1469Article in journal (Refereed)
    Abstract [en]

    In order to obtain a robust performance, the established approach when using radial basis function networks (RBF) as metamodels is to add a posteriori bias which is defined by extra orthogonality constraints. We mean that this is not needed, instead the bias can simply be set a priori by using the normal equation, i.e. the bias becomes the corresponding regression model. In this paper we demonstrate that the performance of our suggested approach with a priori bias is in general as good as, or even for many test examples better than, the performance of RBF with a posteriori bias. Using our approach, it is clear that the global response is modelled with the bias and that the details are captured with radial basis functions. The accuracy of the two approaches are investigated by using multiple test functions with different degrees of dimensionality. Furthermore, several modeling criteria, such as the type of radial basis functions used in the RBFs, dimension of the test functions, sampling techniques and size of samples, are considered to study their affect on the performance of the approaches. The power of RBF with a priori bias for surrogate based design optimization is also demonstrated by solving an established engineering benchmark of a welded beam and another benchmark for different sampling sets generated by successive screening, random, Latin hypercube and Hammersley sampling, respectively. The results obtained by evaluation of the performance metrics, the modeling criteria and the presented optimal solutions, demonstrate promising potentials of our RBF with a priori bias, in addition to the simplicity and straight-forward use of the approach.
