  1. 41. Real-Time GPU Techniques for Advanced Lighting Phenomena

    Författare :Markus Billeter; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Shading; Rendering; Participating Media; Volumetric Shadows; Mobile Graphics; Scattering; Computer Graphics; GPGPU; Many-Light;

    Sammanfattning : In the real world, the visual perception of an object is completely determined by the object's interactions with light. One large application of computer graphics is to visualize virtual objects and worlds in a fashion that is familiar to humans. Successfully emulating light and its effects on virtual objects therefore plays a central role. LÄS MER

  3. 42. Digital innovation and changing identities : investigating organizational implications of digitalization

    Författare :Daniel Nylén; Jonny Holmström; Per Levén; Nicholas Berente; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital innovation; digitalization; platforms; media industry; organizational identity; computer and systems sciences; data- och systemvetenskap;

    Sammanfattning : The emergence of digital technology represents a paradigmatic historical shift. As a process transforming sociotechnical structures, digitalization has had pervasive effects on organizing structures and business logics, as well as contemporary society as a whole. In recent years, these effects have been particularly salient in the content-based (e. LÄS MER

  4. 43. Ethanol from Lignocellulose: Physiological Effects of Inhibitors and Fermentation Strategies

    Författare :Mohammad Taherzadeh Esfahani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fermentation; dilute-acid hydrolyzate; ethanol; hydroxymethyl furfural; furfural; acetic acid; lignocellulose; fed-batch; yeast; pantothenate; control; inhibition; HMF;

    Sammanfattning : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). LÄS MER

  5. 44. Simulations of directionality effects and optical forces in plasmonic nanostructures

    Författare :Vladimir Miljkovic; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Comsol multiphysics; optical forces; nanoparticles; nanowires; DDA; surface plasmons; Green’s function; Mie theory;

    Sammanfattning : With the rapid development of nanoscience and nanotechnology, surface plasmonics based on metal nanoparticles and nanostructures gain increasing interest, not only for fundamental scientific studies, but also for optical and sensor applications. At the nanoscale, the physical and chemical properties of metal particles, especially their optical properties, strongly depend on size and shape, as well as on the surrounding media and structures.

  7. 45. Electronic Mail and its Possible Negative Aspects in Organizational Contexts

    Författare :Eva Sjöqvist; Jacob Palme; Peter Révay; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; E-mail; CMC; miscommunication; negative effects; organizational communication; media choice; communication competence; e-mail competence; Computer and systems science; Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : Electronic mail has become the medium of choice in most organizations because of some of its special features. E-mail, like all computer-mediated communication, changes the way we interact and has therefore an impact on working conditions, sometimes in a negative direction. LÄS MER
