  2. 16. Modelling and Management of Uncertainty in Production Systems : from Measurement to Decision

    Author : Károly Szipka; Andreas Archenti; Sten Dr. Bergstrand; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precision engineering; Uncertainty modelling; Machin-ing system capability; Production Engineering; Industriell produktion;

    Abstract : The advanced handling of uncertainties arising from a wide range of sources is fundamental in quality control and dependability to reach advantageous decisions in different organizational levels of industry. Es-pecially in the competitive edge of production, uncertainty shall not be solely object of estimation but the result of a systematic management process. READ MORE

  4. 17. On MIMO Systems and Adaptive Arrays for Wireless Communication : Analysis and Practical Aspects

    Author : Mattias Wennström; Michael A. Jensen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; antenna array; calibration; MIMO system; flat fading; non-linear amplifier; switched parasitic antenna; analog beamformer; adaptive antenna testbed; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

    Abstract : This thesis is concerned with the use of multiple antenna elements in wireless communication over frequency non-selective radio channels. Both measurement results and theoretical analysis are presented. New transmit strategies are derived and compared to existing transmit strategies, such as beamforming and space-time block coding (STBC). READ MORE

  5. 18. Radio resource management for wireless indoor communication systems : performance and implementation aspects

    Author : Stefan Pettersson; KTH; []
    Keywords : Radio resource management; indoor communication; the bunch concept; centralized RRM; dynamic channel allocation; channel selection;

    Abstract : In this thesis, we investigate several radio resourcemanagement (RRM) techniques and concepts in an indoorenvironment with a dense infrastructure. Future wireless indoorcommunication networks will very likely be implemented atplaces where the user concentration is very high. At these hotspots, the radio resources must be used efficiently.

  6. 19. Cognitive abilities - aspects of structure, process and measurement

    Author : Berit Carlstedt; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognitive abilities; factor models of intelligence; Enlistment battery; hierarchical models; item sequencing; construct validity; differentiation hypothesis; test evaluation; structural equation modeling;

    Abstract : The overall purpose of the thesis is to describe the development of the Swedish system of measuring cognitive abilities applied at enlistment of conscripts. The Enlistment Battery has been used for more than fifty years to classify 18-year old men into military positions for their compulsory service. READ MORE

  7. 20. Mapping bathymetry : From measurement to applications

    Author : Benjamin Hell; Martin Jakobsson; Michele Rebesco; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ocean and coastal mapping; Digital Bathymetric Model; Geographical Information System; Applications of bathymetric data; Baltic Sea; Arctic Ocean; Seafloor morphology; Ocean circulation; Other earth sciences; Övrig geovetenskap; Marine Geoscience; marin geovetenskap;

    Abstract : Surface elevation is likely the most fundamental property of our planet. In contrast to land topography, bathymetry, its underwater equivalent, remains uncertain in many parts of the World ocean. Bathymetry is relevant for a wide range of research topics and for a variety of societal needs. READ MORE
