    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smart cities; smart mobility; urban mobility; mobile crowdsensing; route journey planning; route optimisation; heuristic algorithms; smarta städer; smart rörlighet; rörlighetsavkänning; mobil publikmätning; ruttplanering; ruttoptimering; heuristiska algoritmer; Ciudades inteligentes; movilidad inteligente; mobile crowdsensing; planificación de viajes rutas; optimización de rutas; algoritmos heurísticos; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Urban mobility is often considered as one of the main facilitators for greener and more sustainable urban development. However, nowadays it requires a significant shift towards cleaner and more efficient urban transport which would support for increased social and economic concentration of resources in cities.

  4. 2. The three-dimensional normal-distributions transform : an efficient representation for registration, surface analysis, and loop detection

    Author : Martin Magnusson; Achim Lilienthal; Wolfram Burgard; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NDT; 3D sensing; surface representation; registration; loop detection; surface analysis; mobile robotics; localisation; mapping; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Abstract : This dissertation is concerned with three-dimensional (3D) sensing and 3D scan representation. Three-dimensional records are important tools in several disciplines; such as medical imaging, archaeology, and mobile robotics. READ MORE

  5. 3. Spin ice and demagnetising theory

    Author : Mikael Twengström; Patrik Henelius; Peter Holdsworth; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geometrical frustration; spin ice; Monte Carlo simulations; demagnetising theory; special temperatures; Ewald summation; neutron scattering; structure factors; loop algorithms; parallel tempering; frustrated ferromagnets; equilibration issues; long-range interactions; exchange interactions.; Fysik; Physics;

    Abstract : Frustration, or the inability to simultaneously minimise all local interactions is, a phenomenon occurring in a broad number of physical systems. We will in this thesis focus on a class of frustrated ferromagnetic materials called spin ices and how both numerical and experimental techniques can be used to understand their properties.

  6. 4. Found speech and humans in the loop : Ways to gain insight into large quantities of speech

    Author : Per Fallgren; Jens Edlund; Fred Cummins; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Found data; found speech; human-in-the-loop; sound browsing; dimensionality reduction; visualization; crowdsourcing; Tal- och musikkommunikation; Speech and Music Communication;

    Abstract : Found data - data used for something other than the purpose for which it was originally collected - holds great value in many regards. It typically reflects high ecological validity, a strong cultural worth, and there are significant quantities at hand. However, it is noisy, hard to search through, and its contents are often largely unknown. READ MORE

  7. 5. On Receiver Algorithms for OFDM Systems

    Author : Florent Munier; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quantisation; multicarrier modulation; Intercarrier Interference ICI ; Phase noise; Wiener process; orthogonal frequency division multiplexing OFDM ; estimation; fading channels; channel estimation; iterative decoding.;

    Abstract : This thesis addresses the problem of designing a receiver for an Orthogonal FrequencyDivisionMultiplexing (OFDM)communication system operating over fading channels, taking into account the effects of hardware imperfections. We discuss solutions for efficiently estimating the parameters of a channel model and for compensating oscillator phase noise and analog to digital converter (ADC) quantisation errors at the receiver.
