   Sammanfattning : The thesis consists of five papers which are divided into three main parts. Parts A and B deal with active noise control in a propeller aircraft application, whereas Part C deals with active noise control in a helicopter application. LÄS MER

3. 2. Exploring Strategies for the Combination of Multiple Space-geodetic Techniques

   Författare :Periklis Diamantidis; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Space Geodesy; GNSS; Combination on the Observation Level; EOP; Reference Systems; VLBI; Local Ties;

   Sammanfattning : Space-geodetic techniques are based on signal acquisition from extraterrestrial radio sources that can be used to infer geodetic positioning and define Earth-fixed and inertial reference systems. These techniques, which include Very Long Baseline Interferometry (VLBI) and Global Navigation Satellite Systems (GNSS) among others, exhibit different strengths and weaknesses in recovering parameters of interest.

4. 3. Active Noise Control of Enclosed Sound Fields Optimising the Performance

   Författare :Per Sjösten; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimising actuator and sensor positions; hybrid controller for anc; fast feedforward algorithm; multiple-error algorithm; active noise control; complex lms; multichannel feedforward algorithm; simulated annealing; mean-field annealing; multiple-reference controller;

   Sammanfattning : Active noise control is the art of reducing a primary unwanted sound field by interference with an actively created secondary sound field. To achieve high reduction, it is crucial to obtain both temporal and spatial matching between the primary and the secondary sound fields. LÄS MER

5. 4. Human leukocyte antigens with special reference to association and linkage in multiple sclerosis

   Författare :Anna Fogdell-Hahn; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :HLA; MHC; multiple sclerosis; narcolepsy; lod score; linkage.;

   Sammanfattning : The polymorphism of HLA (human leukocyte antigen) is extensive. Allelic variation has previously been detected by cellular and serological methods. Today a variety of genomic typing techniques have been developed, which give higher resolution and a possibility to detect single nucleotide variations. LÄS MER

7. 5. Reference Architectures for Highly Automated Driving

   Författare :Sagar Behere; Martin Törngren; Ivica Crnkovic; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous driving; E E Architecture; Systems Engineering; Machine Design; Maskinkonstruktion;

   Sammanfattning : Highly automated driving systems promise increased road traffic safety, as well as positive impacts on sustainable transportation by means of increased traffic efficiency and environmental friendliness. The design and development of such systems require scientific advances in a number of areas. LÄS MER
