  1. 26. Enhanced engineering of component-based industrial automation systems using formal methods

    Författare :Sandeep Patil; Valeriy Vyatkin; Georg Frey; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : Industrial automation is facing challenges related to a manufacturing change from mass pro-duction to mass customization. As a result, the focus of automation has been shifting to flexi-bility, reconfigurability and safety assurance resulting in a new class of systems that is heavilymodular. LÄS MER

  3. 27. Acoustic scattering in ducts and influence of flow coupling

    Författare :Susann Boij; KTH; []
    Nyckelord :sound; vortex sheet; flow separation; end correction; Strouhal number; non-orthogonal modes; energy balance; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The subject of this thesis is the acoustic properties offlow duct area expansions and the influence of flow-acousticcoupling at sharp edges. For low Mach number flow, significantinteraction between the sound field and the flow field canoccur at such points of flow separation. LÄS MER

  4. 28. Compensation for hearing loss and cancellation of acoustic feedback indigital hearing aids

    Författare :Johan Hellgren; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The development of integrated circuits during the last decades has made it possible to incorporate digital signal processing in hearing aids that fit into the ear canal and are powered by small zink-air batteries. The digital signal processing provides new possibilities for the hearing aid to modify the signal to fit the impaired ear. LÄS MER

  5. 29. Tunable photonic crystals based on carbon nanofibers

    Författare :Robert Rehammar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; FDTD; PECVD; Photonic crystal; carbon nanofiber; tunable; diffraction; ellipsometry;

    Sammanfattning : Photonic crystals are materials with periodically varying refractive indices. In conventional photonic crystal design it is hard to achieve tunable structures in the visible range, i.e. structures with changeable optical properties. LÄS MER

  7. 30. Digital Hardware Aspects of Multiantenna Algorithms

    Författare :Fredrik Edman; Institutionen för elektro- och informationsteknik; []
