  2. 6. Community-based customer involvement for improving packaged software development

    Author : Helena Holmström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Packaged software development; software improvement; virtual communities; customer involvement; community knowledge; community-based customer involvement;

    Abstract : Noting the widespread use of virtual communities for interacting with customers, this thesis explores the role of virtual communities for involving distributed customers in packaged software development (psd) and the opportunities and challenges that are associated with this. While the idea of involving customers in software development is not new, it is yet to gain momentum in psd. READ MORE

  4. 7. Peak and Power Reduction in Multicarrier Communication Systems

    Author : Niklas Andgart; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; line driver; Signal processing; Signalbehandling; Telecommunication engineering; power reduction; DSL; DMT; tone reservation; PAR; Peak to average ratio;

    Abstract : Broadband multicarrier communication suffers from a large signal span, causing problems in both wireless and wireline systems. This is commonly referred to as a high peak to average ratio (PAR), and leads to a high power consumption, which is an important limitation in many communication systems. READ MORE

  5. 8. Megalin, an Endocytotic Receptor with Signalling Potential

    Author : Mårten Larsson; Lars Rask; Bo Åkerström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Megalin; LRP-2; Postsynaptic density-95; Retinol-binding protein; Oligodendrocytes; Central nervous system; Biokemi; Biochemistry; Biokemi;

    Abstract : Megalin is an endocytotic receptor belonging to the low-density lipoprotein family. It has often been viewed only as merely a scavenger receptor of absorptive and secretory epithelia. Recent work has revealed that the megalin intracellular domain contains several motifs potentially binding proteins involved in signal transduction. READ MORE

  6. 9. On surface structure characterization and application on additive manufacturing

    Author : Olena Flys; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; surface texture parameters.; fused deposition modelling; power spectral density; coherence scanning interferometer; selective laser melting; Surface characterization;

    Abstract : Countless industrial applications over the past decades have indicated the increased need to relate surface texture to surface function. The fast-growing industry of additive manufacturing admits the surface roughness as one of the main challenges. READ MORE

  7. 10. Micro-by-micro interactions : Aggregation dynamics, biofilms, and ecotoxicological impacts of suspended solids

    Author : Sophia Reichelt; Elena Gorokhova; Rehab El Shehawy; Julien Gigault; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; suspended solids; microplastics; bacteria; biofilm; aggregation; ecotoxicology; microalgae; Environmental Sciences; miljövetenskap;

    Abstract : Increasing concerns arise regarding the environmental risk of microplastics (MP) and their interactions with biota, prompting numerous effect studies. However, current ecotoxicology methods fall short when it comes to assessing MP impacts. READ MORE
