1. 1. Large-Scale Information Acquisition for Data and Information Fusion

   Författare :Ronnie Johansson; Henrik I. Christensen; David Nicholson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sensor management; perception management; data fusion; information fusion; large-scale information acquisition; multi-agent coordination protocol; axiomatic bargaining theory; particle filter tracking; pyro-electric infrared sensor; multi-robot system; Computer science; Datalogi;

   Sammanfattning : The purpose of information acquisition for data and information fusion is to provide relevant and timely information. The acquired information is integrated (or fused) to estimate the state of some environment. LÄS MER

3. 2. The DAQ always runs - Performing large scale nuclear physics experiments

   Författare :Håkan T Johansson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radioactive Beams; Exotic Nuclei; Data Acquisition; Calibrations; Analysis;

   Sammanfattning : An important part and a growing field of modern subatomic physics is the study of exotic isotopes using radioactive beams. The experiments started out simple. Along with a better and more detailed understanding, together with the availability of new technology, the experiments are becoming more and more advanced. LÄS MER

4. 3. Articulation Rate and Surprisal in Swedish Child-Directed Speech

   Författare :Johan Sjons; Mats Wirén; Robert Östling; Iris-Corinna Schwarz; Francisco Lacerda; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; articulation rate; information-theoretic surprisal; child-directed speech; final lengthening; spontaneous; longitudinal;

   Sammanfattning : Child-directed speech (CDS) differs from adult-directed speech (ADS) in several respects whose possible facilitating effects for language acquisition are still being studied. One such difference concerns articulation rate --- the number of linguistic units by the number of time units, excluding pauses --- which has been shown to be generally lower than in ADS. LÄS MER

5. 4. Hydropower generator and power system interaction

   Författare :Johan Bladh; Urban Lundin; Rafael Escarela-Perez; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amortisseur windings; applied voltage test; automatic voltage regulators; damper windings; damping torque; empirical modelling; equivalent circuits; excitation control; finite element method; hydropower generators; power system restoration; power system stability; synchronous machines; self excitation; shaft torque amplification; short circuit test; single machine infinite bus; slip test; standstill frequency response test; subsynchronous oscillations; synchronising torque; synchronous generators; torsional interaction.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : After decades of routine operation, the hydropower industry faces new challenges. Large-scale integration of other renewable sources of generation in the power system accentuates the role of hydropower as a regulating resource. LÄS MER

7. 5. Compression-based Data Identification and Representation Learning

   Författare :Hanwei Wu; Markus Flierl; Mikael Skoglund; Conci Nicola; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Large-scale data generation, acquisition, and processing are happening at everymoment in our society. This thesis explores the opportunities for applying lossycompression methods and concepts for improving information engineering techniquesthat transform a large amount of collected data into useful applications.
