1. 16. Studies on hybrid superconducting junctions

   Författare :Cecilia Holmqvist; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Critical Current; Single-Electron Box; Attractive Correlations; Josephson Junction; Negative Charging Energy; Quasiclassical Superconductivity; Josephson Current;

   Sammanfattning : In the field of nanoelectronics, one seeks to combine quantum mechanical effects with macroscopic entities such as currents in order to find new ways of storing and manipulating information. One possibility to accomplish this is to use the quantum correlations found in superconductors. LÄS MER

3. 17. Using Molecular Dynamics Simulations to Explore Critical Property Relationships in Polymer Electrolytes : Polarity, Coordination, Ionic transport, Ion-pairing, and Ion-ion Correlations

   Författare :Harish Gudla; Daniel Brandell; Chao Zhang; Andreas Heuer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid polymer electrolytes; molecular dynamics simulations; solvent polarity; ion-pairing; ion coordination; ion transport mechanisms; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Sammanfattning : While ion transport in solid polymer electrolytes (SPEs) has been explored for decades, there still remains controversies about its fundamental properties, often correlated with gaps between experimental and computational studies. Using molecular dynamics simulations to understand the complex transport mechanisms and also to fill these gaps is the main goal of this thesis. LÄS MER

4. 18. Essays on the Transmission of Human Capital and the Impact of Technological Change

   Författare :Adrian Adermon; Mikael Lindahl; Magnus Gustavsson; Markus Jäntti; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; education; intergenerational mobility; sibling correlations; natural experiment; copyright; music; movies; file sharing; piracy; inequality; job polarization; task-biased technological change; Economics; Nationalekonomi;

   Sammanfattning : Essay 1: If grandparents have an independent impact on their grandchildren's schooling, intergenerational correlations estimated using two generations will underestimate the true level of intergenerational persistence in education. Recent research has found such multi-generational effects, but there is still no consensus on whether these estimates are due to a direct impact of grandparents on their grandchildren, or if they arise because of measurement error or model misspecification.

5. 19. Dynamics of particles in fluids: effects of correlations and interactions

   Författare :Anshuman Dubey; Göteborgs universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; particle-laden flows; turbulent aerosols; collisions; charged droplets; hydrodynamic interactions;

   Sammanfattning : Particles suspended in turbulent fluid flows are common in Nature and in technological applications. In some cases, the relative dynamics of spherical particles may be of interest. One example is small rain droplets in turbulent clouds. The dynamics of nearby droplets is correlated because they experience a correlated airflow. LÄS MER

7. 20. Privacy Mechanism Design Through the Lens of Information Theory : With Applications to Compression, Caching, and Semantic Communication

   Författare :Amirreza Zamani; Mikael Skoglund; Tobias J. Oechtering; Parastoo Sadeghi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Privacy mechanism design; Leakage matrix; Strong privacy criterion; KL-divergence; Local approximation; Euclidean information geometry; Privacy-utility trade-off; χ2-privacy criterion; l1-privacy criterion; Common information; Functional representation lemma; Two-part construction coding; Design av sekretessmekanism; Läckagematris; Stark sekretesskriterium; KL-divergens; Lokal approximation; Euklidisk informationsgeometri; Sekretess-nyttoavvägning; χ2-sekretesskriterium; l1-sekretesskriterium; Gemensam information; Lemma för funktionell representation; Kodning med tvådelad konstruktion.; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Privacy mechanism design is an important research area and is receiving increased attention in recent years. This field focuses on addressing the challenge of revealing general data that might have correlations with sensitive information, all while protecting this sensitive information against unauthorized access.
