  1. 1. Virtual infrastructures for computational science: software and architectures for distributed job and resource management

    Author : Per-Olov Östberg; Erik Elmroth; Odej Kao; Umeå universitet; []
    Keywords : ;

    Abstract : In computational science, the scale of problems addressed and the resolution of solu- tions achieved are often limited by the available computational capacity. The current methodology of scaling computational capacity to large scale (i.e. READ MORE

  2. 2. Live VM Migration : Principles and Performance

    Author : Petter Svärd; Erik Elmroth; Eric Jul; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Live Migration; Virtualization; business data processing; administrativ databehandling;

    Abstract : Virtualization is a key technology for cloud computing as it allows several operating system instances to run on the same machine, enhances resource manageability and enables flexible definition of billing units. Virtualization works by adding a software layer, a hypervisor, on top of the hardware platform. READ MORE

  3. 3. Human brains and virtual realities : Computer-generated presence in theory and practice

    Author : Daniel Sjölie; Lars-Erik Janlert; Johan Eriksson; Giuseppe Riva; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human brain function; virtual reality; presence; cognitive neuroscience; human-computer interaction; brain imaging; fMRI; BCI; neural correlates; HCI theory; reality-based interaction.;

    Abstract : A combined view of the human brain and computer-generated virtual realities is motivated by recent developments in cognitive neuroscience and human-computer interaction (HCI). The emergence of new theories of human brain function, together with an increasing use of realistic human-computer interaction, give reason to believe that a better understanding of the relationship between human brains and virtual realities is both possible and valuable.

  4. 4. Targeting Children Online : Young internet users and producers in the commercial media environment

    Author : Carolina Martinez; Medie- och kommunikationsvetenskap; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; internetreklam; internet; reklamspel; barn; reklamproducenter; marknadsförare; mobilspel; virtuella världar; online advertising; internet; mobile games; children; advertising professionals; marketers; virtual worlds; tactics;

    Abstract : Children’s daily internet usage takes place to a large extent in a commercial environment, where advertising and the sale of virtual goods are ever-present parts of the online experience. The overall goal of this thesis is to contribute to a critical understanding of children’s commercial online environment as spaces for children’s everyday life activities and participation, and as spaces for commercial interests that seek to target children and monetize their internet usage.

  5. 5. Effects of environmental acoustic factors, individual differences and musical training on speech perception in simulated classrooms

    Author : Douglas MacCutcheon; Robert Ljung; Daniel Västfjäll; Högskolan i Gävle; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; speech in noise; cognition; perception; musical training; spatial listening; virtual classroom environment; bakgrundsljud; kognition; taluppfattning; musikalisk träning; rumsligt lyssnande; virtuella klassrumsmiljöer; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : Formal learning takes place primarily through speech perception in classroom environments and is therefore dependent on the listener’s ability to cope with a number of acoustic factors that interfere with the speech signal. As classrooms are inclusive spaces accommodating learners with a broad range of abilities and backgrounds, this research investigated some of the ways in which individual differences in supporting cognitive skills are related to speech perception outcomes in various challenging acoustic environments.
