  1. 41. Robust Low-Power Wide Area Networks for Sports and Health

    Författare :Charalampos Orfanidis; Martin Jacobsson; Dimitrios Zorbas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology and Health; Teknik och hälsa;

    Sammanfattning : Low-Power Wide Area Networks (LPWANs) has enriched the IoT ecosystem with new features and application scenarios. LPWANs offer long range communication and can be used to connect devices that are divided by long distances and offer connectivity to remote areas where cellular networks are not accessible. LÄS MER

  3. 42. Acoustic Manipulation of Particles and Fluids in Microfluidic Systems

    Författare :Linda Johansson; Stefan Johansson; Martin Wiklund; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : The downscaling and integration of biomedical analyses onto a single chip offers several advantages in speed, cost, parallelism and de-centralization. Acoustic radiation forces are attractive to use in these applications since they are strong, long-range and gentle. LÄS MER

  4. 43. Sound propagation around off-shore wind turbines

    Författare :Lisa Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind turbine noise; off-shore wind powe; long-rage sound propagation; parabolic equation; scattering; water waves; Building engineering; Byggnadsteknik;

    Sammanfattning : Low-frequency, long-range sound propagation over a seasurface has been calculated using a wide-angel Cranck-NicholsonParabolic Equation method. The model is developed toinvestigate noise from off-shore wind turbines. Thecalculations are made using normal meteorological conditions ofthe Baltic Sea. LÄS MER

  5. 44. Theoretical and Numerical Studies of Efimov States

    Författare :Kajsa-My Blomdahl; Svante Jonsell; Michael Odelius; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : In contrast to the classical case, the quantum three-body problem is amenable to qualitative analysis and, in some cases, even to analytic solutions. In 1970, Vitaly Efimov predicted that resonant two-body forces could give rise to a series of bound energy levels in three-particle systems. LÄS MER

  7. 45. Motivating External Participation in Marketing Intelligence Foresight

    Författare :Andrew Flostrand; Esmail Salehi-Sangari; Leyland Pitt; Victoria L. Crittenden; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; marketing intelligence; stakeholder engagement; self-determination theory; Delphi technique; crowdsourcing; foresight; motivation; technological forecasting; social forecasting; Industrial Marketing; Industriell marknadsföring;

    Sammanfattning : Long-range planning for purposes of deciding on the development of high investment and long development cycle activities requires that assumptions be made about environmental factors at the time of their future completion. For organizations that serve a market, the future market factors related to supply, demand, and technological developments are at once fundamentally critical and unknowable  with certainty. LÄS MER
