  1. 1. Development of a new service-oriented modelling method for information systems analysis and design

    Författare :Prima Gustiené; Anders G Nilsson; Sten Carlsson; William Wei Song; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information systems analysis and design; conceptual modeling; service orientation; semantic integrity; static and dynamic aspects; goal modeling.; Informatics; Informatik; Information Systems; Informatik;

    Sammanfattning : This thesis presents a new modelling method for information systems analysis and design, where the concept of service and the principles of service orientation are used for integrated modelling and reasoning about information systems architectures across organisational and technical systems boundaries. The concept of service enables cohesion of the intersubjective and objective modelling traditions by using a single type of diagram that facilitates detection of semantic inconsistency, incompleteness, ambiguity and discontinuity between the static and dynamic aspects of information systems specifications.

  3. 2. Information-Theoretic Generalization Bounds: Tightness and Expressiveness

    Författare :Fredrik Hellström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; information theory; neural networks; generalization; statistical learning; meta learning; PAC-Bayes; Machine learning;

    Sammanfattning : Machine learning has achieved impressive feats in numerous domains, largely driven by the emergence of deep neural networks. Due to the high complexity of these models, classical bounds on the generalization error---that is, the difference between training and test performance---fail to explain this success. LÄS MER

  4. 3. Information Systems Actability : Understanding Information Technology as a Tool for Business Action and Communication

    Författare :Pär J. Ågerfalk; Göran Goldkuhl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; information systems; information systems actability; Internet-based information systems; language action perspective; Information technology; Informationsteknologi;

    Sammanfattning : This dissertation is devoted to a perspective from which IT-based information systems are conceived as information technological artefacts intended for business action and communication. The perspective has been made concrete through the concept of information systems actability, which is the main concept under scrutiny. LÄS MER

  5. 4. Information Sharing and the Bullwhip Effect Reduction : A new Prespective Through the Lens of Blockchain Technology

    Författare :Muthana Al-Sukhni; Athanasios Migdalas; Stefan Engevall; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bullwhip Effect; Information Sharing; Information Communication Systems; Blockchain Technology; Supply Chain Dynamics; Emerging Technologies; Digitization; Information Sharing Aspects; Inter-Organizational Coordination; Kvalitetsteknik och logistik; Quality Technology and Logistics;

    Sammanfattning : Globalization and the surge of competition across industries forced companies to improve their supply chain capabilities to serve their customers efficiently and effectively. Due to this fact, businesses are no longer capable of handling all supply chain operations without collaboration and coordination with other firms. LÄS MER

  7. 5. Enabling Media : Infrastructures, imaginaries and cultural techniques in Swedish and Estonian visual arts education

    Författare :Ingrid Forsler; Michael Forsman; Staffan Ericson; Geoffrey Bowker; Södertörns högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; visual arts education; teacher training; educational technology; Sweden; Estonia; infrastructures; cultural techniques; sociotechnical imaginaries; visual methods; infrastructural imagination; media literacy; infrastructure literacy; bildämnet; lärarutbildning; utbildningsteknologier; Sverige; Estland; infrastrukturer; kulturtekniker; sociotekniska föreställningar; visuella metoder; infrastrukturell föreställningsförmåga; mediekunnighet; infrastrukturlitteracitet; Media and communication studies; Medie- och kommunikationsvetenskap; Kritisk kulturteori; Critical and Cultural Theory; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : This dissertation explores the media environments of visual arts education in Sweden and Estonia and how educators understand, negotiate and enable this infrastructure. Based on the notion that the ongoing digitalization of the educational system in these countries makes established practices appear, it further discusses how visual arts education as a school subject is shaped in relation to different technologies for image making and school administration.
