  2. 16. Breaking the Unbreakable : Exploiting Loopholes in Bell’s Theorem to Hack Quantum Cryptography

    Author : Jonathan Jogenfors; Jan-Åke Larsson; Fredrik Karlsson; Marek Żukowski; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis we study device-independent quantum key distribution based on energy-time entanglement. This is a method for cryptography that promises not only perfect secrecy, but also to be a practical method for quantum key distribution thanks to the reduced complexity when compared to other quantum key distribution protocols.

  4. 17. Effects of retrieval and articulation on memory

    Author : Max Larsson Sundqvist; Fredrik Jönsson; Timo Mäntylä; Peter Verkoeijen; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; testing effect; covert retrieval; overt retrieval; judgments of learning; delayed JOL effect; response format; retention interval; Psychology; psykologi;

    Abstract : Many would agree that learning occurs when new information is stored in memory. Therefore, most learning efforts typically focus on encoding processes, such as additional study or other forms of repetition. However, as I will outline in this thesis, there are other means by which to improve memory, such as retrieval practice in the form of tests. READ MORE

  5. 18. Peak Shear Strength of Rock Joints – Towards a Methodology for Prediction Based on Field Data

    Author : Francisco Ríos Bayona; Fredrik Johansson; Diego Mas Ivars; Stefan Larsson; José Muralha; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock joints; peak shear strength; DEM; matedness; aperture; Bergssprickor; skjuvhållfasthet; DEM; sprickans passning; sprickvidd; Jord- och bergmekanik; Soil and Rock Mechanics;

    Abstract : The rock joint shear strength at field scale is an important design parameter and remains a challenge for rock mechanics engineers. In Sweden, there exist a large number of concrete dams that are founded on rock masses which in many cases contain sub-horizontal rock joints. READ MORE

  6. 19. Tribology of Carbon Based Coatings for Machine Element Applications

    Author : Fredrik Svahn; Åsa Kassman-Rudolphi; Sture Hogmark; Mats Larsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : Demands on lower fuel consumption, reduced pollution, increased operating times, etc. force the automotive industry to constantly improve the performance of critical machine elements. In this development various carbon based coatings have proven very promising, mainly because of their low friction and high wear resistance in dry sliding contacts. READ MORE

  7. 20. Short- and long-term consequences of sport-related concussion

    Author : Fredrik Vedung; Niklas Marklund; Gunnar Antoni; Elna-Marie Larsson; Jakob Johansson; Alexander Olsen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sport-related concussion; Soccer; Traumatic brain injury; tau; neuroinflammation; cerebral blood flow; Neurokirurgi; Neurosurgery;

    Abstract : Concussions are common in contact sports. Symptoms such as confusion and/or loss of consciousness following an impact to the head indicate that a sport-related concussion (SRC) has occurred. The symptoms normally resolve within 10-14 days following an SRC in adults although at least 10 % of athletes suffer from prolonged symptoms. READ MORE
