  2. 16. Selection of stimuli for listening tests by software-assisted ranking

    Author : Jonas Ekeroot; Nicholas Zacharov; Luleå tekniska universitet; []
    Keywords : HUMANIORA; HUMANITIES; Ljudteknik; Audio Technology;

    Abstract : Within the academic field of audio technology, which is the context of this thesis, research questions related to various forms of perceptual audio evaluation of different types of audio systems are important and commonly encountered. Methods for systematic evaluations of listeners’ perceived audio quality, based on different experimental designs, have evolved over a time span of several decades and are collectively referred to as listening tests.

  4. 17. Narrowing the gap between network models and real complex systems

    Author : Alcides Viamontes Esquivel; Martin Rosvall; Joachim Mathiesen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; complex systems; network science; community detection; model selection; signficance analysis; ergodicity; fysik; Physics;

    Abstract : Simple network models that focus only on graph topology or, at best, basic interactions are often insufficient to capture all the aspects of a dynamic complex system. In this thesis, I explore those limitations, and some concrete methods of resolving them. READ MORE

  5. 18. On Tool Failure in Die Casting

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Die casting is a very cost-efficient method of forming thin-walled and complex near net-shaped products with close geometric tolerances and good surface finish. A permanent die tool is used to make large quantities of identical products. The performance and tool life are limited by several mechanisms, e.g. READ MORE

  7. 20. Evolution and transcriptional regulation of Kindlins

    Author : Ammad Khan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Kindlins are relatively newly discovered focal adhesion proteins. The Kindlin family includes three highly conserved proteins: Kindlin-1, Kindlin-2 and Kindlin-3. All three Kindlins have been shown to interact with Integrin and this interaction plays important role in the functional properties of Kindlins. READ MORE
