  1. 31. Three-wave mixing in Josephson travelling-wave parametric amplifiers

    Författare :Hampus Renberg Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-wave mixing; lumped-element; four-wave mixing; SNAIL; Josephson junction; travelling-wave parametric amplifier; parametric amplifier; parametric amplification; resonant phase matching.; rf-SQUID;

    Sammanfattning : This work explores possibilities of building a wide-band, quantum-limited low-noise amplifier by means of three-wave mixing (3WM) in different kinds of Josephson travelling-wave parametric amplifiers (TWPAs). We extend the theory of the continuous three-mode model to include any number of up-converted modes in the small frequency limit where the frequency dispersion is close to linear. LÄS MER

  3. 32. Homotopy automorphisms, graph complexes, and modular operads

    Författare :Robin Stoll; Alexander Berglund; Manuel Krannich; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; matematik; Mathematics;

    Sammanfattning : This licentiate thesis consists of two papers.In Paper I we identify the cohomology of the stable classifying space of homotopy automorphisms (relative to an embedded disk) of connected sums of S^k × S^l, where 3 ≤ k < l ≤ 2k − 2. We express the result in terms of Lie graph complex homology. LÄS MER

  4. 33. Weighted multidimensional integral inequalities and applications

    Författare :Sorina Barza; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : In this thesis some new weighted integral inequalities for monotone functions in higher dimensions are proved. These results extend previous results in one dimension, and also those in higher dimensions for particular choices of the weights (power weights, etc.). All inequalities are sharp. LÄS MER

  5. 34. Exploring competence and workplace learning in supply chain management

    Författare :Pernilla Derwik; Förpackningslogistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Competence in supply chain management (SCM) is a key factor for achieving superior business performance. The top 25 companies identified as having excellent competence in SCM in the annual research reports by AMR Research/Gartner have displayed substantially higher financial results than their competitors.

  7. 35. The Lord of Their Data Under the GDPR? : Empowering Users Through Usable Transparency, Intervenability, and Consent

    Författare :Farzaneh Karegar; Simone Fischer-Hübner; John Sören Pettersson; Sameer Patil; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Control of personal data; Data privacy; GDPR; HCI; Informed consent; Transparency-enhancing tool; Usability; User interface design; Computer Science; Datavetenskap;

    Sammanfattning : The challenges imposed by the ever-growing online data processing make it difficult for people to control their data, which inevitably imperils the privacy of their personal information and making informed decisions. Thus, there is an increasing need for different societal, technological, and legal solutions that empower users to take control of their data. LÄS MER
