  2. 1. Modeling of Elasticity and Damping for Filled Elastomers

    Author : Per Erik Austrell; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological models; contact-free strain measurement; modified hardness test; solid dumbbell test specimen; mechanical conditioning; strain energy plot; hyperelasticity; carbon-black-filled rubbers; amplitude dependence; multiaxial viscoplastic model; Building construction; Byggnadsteknik;

    Abstract : Elasticity and damping are significant properties of rubber, taken advantage of in engineering applications. It is therefore important that the constitutive model accurately captures these aspects of the mechanical behavior. READ MORE

  4. 2. Efficient governance of construction projects through cooperative procurement procedures

    Author : Per-Erik Eriksson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Entreprenörskap och innovation; Entrepreneurship and Innovation;

    Abstract : The purpose of this research is to increase the understanding of how efficient governance of construction projects can be achieved through appropriate procurement procedures. In this PhD project, literature reviews, a pre-study, a longitudinal case study and a survey study have been conducted in order to investigate five research questions and thereby fulfil the research purpose.

  5. 3. Videography as Design Nexus : Critical Inquires into the Affordances and Efficacies of Live-action Video Instructions

    Author : Per Erik Eriksson; Yvonne Eriksson; Fredrik Lindstrand; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information Design; Instructions; Video; Engagement; Perception; Human-Centered Design; Innovation and Design; innovation och design; Interkulturella studier;

    Abstract : This thesis is about live-action instructional videos (LAVs). By addressing design problems with respect to the how-to video genre, the thesis asks fundamental questions about mediated instructional communication efficacies and the factors that either obstruct or augment them.

  6. 4. Videography as production nexus : digital film cameras, media mangement and the distribution of creativity

    Author : Per Erik Eriksson; Yvonne Eriksson; Ingemar Grandin; Högskolan Dalarna; []
    Keywords : videography; media management; creativity; Kreativa beslut i produktionssituation inom filmproduktion; Kreativa beslut i produktionssituation inom filmproduktion; Innovation and Design;

    Abstract : This thesis is about new digital moving image recording technologies and how they augment the distribution of creativity and the flexibility in moving image production systems, but also impose constraints on how images flow through the production system. The central concept developed in this thesis is ‘creative space’ which links quality and efficiency in moving image production to time for creative work, capacity of digital tools, user skills and the constitution of digital moving image material.

  7. 5. Sparse Representations for Medium Level Vision

    Author : Per-Erik Forssén; Gösta Granlund; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In this thesis a new type of representation for medium level vision operations is explored. We focus on representations that are sparse and monopolar. The word sparse signifies that information in the feature sets used is not necessarily present at all points. On the contrary, most features will be inactive. READ MORE
