  1. 1. 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

  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. Beyond IT and Productivity : Effects of Digitized Information Flows in Health Care

    Författare :Pontus Fryk; Thomas Falk; Nils-Göran Olve; Mats Edenius; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Health Care; Productivity Paradox; Information Technology; Productivity; Process; Information; Communication; Economy; Business and economics; Ekonomi; Economic Information Systems; Ekonomiska informationssystem;

    Sammanfattning : Denna avhandling undersöker hur investeringar i IT, och digitaliseringen av informationsflöden, har påverkat produktiviteten inom sjukvården. Genom empiriska undersökningar av avgränsade sjukvårdsprocesser – samt diskussioner baserade på idéer och teorier relaterade till ekonomi, ”produktivitetsparadoxen”, så kallade General Purpose Technologies (GPTs), och medicinsk informatik – detekteras och analyseras effekter av digitaliseringen.

  5. 4. Development and Implementations of Virtual Reality for Decision-making in Urban Planning and Building Design

    Författare :Mattias Roupé; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Building design; Usability; 3D city models; Virtual Reality; Decision making; Urban planning;

    Sammanfattning : The use of Virtual Reality (VR) has been seen by many as holding great potential for increasing the effectiveness and improving communication in the decision making process in urban planning and building design. VR can facilitate processes so that participants can together better understand, identify and analyze problems to improve their decision making and thereby the future urban environment. LÄS MER

  7. 5. Highway Traffic State Estimation and Short-term Prediction

    Författare :Andreas Allström; Jan Lundgren; Clas Rydergren; Balázs Adam Kulcsár; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Traffic congestion is increasing in almost all large cities, leading to a number of negative effects such as pollution and delays. However, building new roads is not a feasible solution. Instead, the use of the existing road network has to be optimized, together with a shift towards more sustainable transport modes. LÄS MER
