  1. 1. SECOND-ORDER DIVERGENCE-FREE FEM FOR MAGNETOHYDRODYNAMICS USING LAGRANGE POLYNOMIALS

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Erik Björklund; Peter Mårtensson; Noah Waltman; [2023]
    Keywords : ;

    Abstract : AbstractMaxwell’s laws state that the divergence of a magnetic field always remains zero. In thecontinuous setting this is true for the magnetohydrodynamics equations. However, in thediscrete setting, the solution does not always remain divergence-free. READ MORE

  4. 3. Solving NTRU Challenges Using the New Progressive BKZ Library

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Erik Mårtensson; [2016]
    Keywords : NTRU Challenge; Progressive BKZ; BDD; Enumeration; SVP; Mathematics and Statistics; Technology and Engineering;

    Abstract : NTRU is a public-key cryptosystem, where the underlying mathematical problem is currently safe against large-scale quantum computer attacks. The system is not as well investigated, as for example RSA, and the company behind NTRU has created the NTRU Challenges, to remedy this. READ MORE

    Abstract : Bardawil Lagoon, a natural lagoon located on the northern coast of the Sinai Peninsula, Egypt, there are three inlets of which two are man-made connecting the lagoon with the Mediterranean Sea. The inlets are subjected to changes in morphology, due to sediment transport, over time and this may lead to degrees of closure of either inlet. READ MORE
