  1. 1. Advanced Thin Film Electroacoustic Devices

    Författare :Johan Bjurström; Ilia Katardjiev; Paul Muralt; Uppsala universitet; []
    Nyckelord :Technology; aluminum nitride; FBAR; shear mode resonator; lamb wave devices; liquid sensor; biosensor; temperature compensation; reactive sputtering; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The explosive development of the telecom industry and in particular wireless and mobile communications in recent years has lead to a rapid development of new component and fabrication technologies to continually satisfy the mutually exclusive requirements for better performance and miniaturization on the one hand and low cost on the other. A fundamental element in radio communications is time and frequency control, which in turn is achieved by high performance electro-acoustic components made on piezoelectric single crystalline substrates.

  3. 2. 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

  4. 3. Resource Allocation for Mobile Edge Computing Systems

    Författare :Ming Zeng; Viktória Fodor; Gunnar Karlsson; Di Yuan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mobile edge computing MEC ; orthogonal multiple access OMA ; non-orthogonal multiple access NOMA ; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The rapid development of mobile information industry has led to the emergence of various mobile applications in areas such as industrial automation, health care or transportation. These applications often require heavy computations with strict latency requirement, which may surpass the processing abilities of the mobile devices. LÄS MER

  5. 4. Interactive sonification of motion : Design, implementation and control of expressive auditory feedback with mobile devices

    Författare :Gaël Dubus; Roberto Bresin; Paul Vickers; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Speech and Music Communication; Tal- och musikkommunikation;

    Sammanfattning : Sound and motion are intrinsically related, by their physical nature and through the link between auditory perception and motor control. If sound provides information about the characteristics of a movement, a movement can also be influenced or triggered by a sound pattern. LÄS MER

  7. 5. Optimal Performance of Advanced Radiating Structures

    Författare :Casimir Ehrenborg; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical Bounds; MIMO Communication; Computational Electromagnetics; Antenna Theory; Optimization Methods; Q-factor;

    Sammanfattning : Requirements on radiating structures are constantly increasing, demand for faster speed, smaller size, and higher reliability drives today's technical development. However, for electrically small structures, less than half-a-wavelength in size, performance is fundamentally limited by physical size. LÄS MER
