1. 1. Taxonomy, phylogeny, and secondary sexual character evolution of diving beetles, focusing on the genus Acilius

   Författare :Johannes Bergsten; Anders N. Nilsson; Jyrki Muona; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; antagonistic coevolution; arms race; sexual conflict; diving beetle; Dytiscidae; Coleoptera; taxon sampling; long-branch attraction; parsimony; Bayesian analysis; taxonomic revision; Biologi; Biology; Biologi;

   Sammanfattning : Sexual conflict can lead to antagonistic coevolution between the sexes, but empirical examples are few. In this thesis secondary sexual characters in diving beetles are interpreted in the light of sexual conflict theory. LÄS MER

3. 2. The analogy as a decision model : a study of management team members in two consulting firms

   Författare :Anders Nilsson; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accounting and Control; Redovisning och styrning;

   Sammanfattning : Decision making is often characterized as the trading-off between means and ends, facilitating a "rational choice". One central argument of this thesis is that the rational actor metaphor is over-emphasized in management theory. LÄS MER

4. 3. Involving concerned significant others in the treatment of problem gambling

   Författare :Anders Nilsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Problem gambling (PG) is a worldwide phenomenon that affects both gamblers and their concerned significant others (CSOs). Apart from financial difficulties, problem gambling is associated with disrupted relationships, poor mental and physical health, and in some cases criminality. LÄS MER

5. 4. Dimensions and projections

   Författare :Anders Nilsson; Peter Wingren; Fredrik Georgsson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fractals; Hausdorff dimension; box dimension; packing dimension; projections; MATHEMATICS; MATEMATIK;

   Sammanfattning : This thesis concerns dimensions and projections of sets that could be described as fractals. The background is applied problems regarding analysis of human tissue. One way to characterize such complicated structures is to estimate the dimension. LÄS MER

7. 5. In-Line Bit Interleaved Serially Concatenated Coded Modulation

   Författare :ANDERS NILSSON; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; serially concatenated codes; the AWGN channel.; Coded modulation; iterative decoding; in-line bit interleaving; turbo codes;

   Sammanfattning : A communication system using in-line bit interleaved serially concatenated trellis coded modulation (SCTCM) over the additive white Gaussian noise (AWGN) channel is investigated. In-line bit interleaving refers to an interleaving method for which the random bit interleaver is divided into several independent constituent bit interleavers. LÄS MER
