  1. 1. Relating the Arnoldi approximation to the best Chebyshev approximation of the characteristic polynomial - A study using a complex valued variant of the Remez algorithm

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Thomas Renström; [2022]
    Keywords : Chebyshev; Arnoldi; Remez; Tang; approximation; matrix; complex; characteristic polynomial; Mathematics and Statistics;

    Abstract : The Remez algorithm is a beautiful algorithm that finds the best approximation to a function by finding points satisfying the alternation condition. In 1987 Ping Tang published his doctoral thesis detailing a version of the Remez algorithm modified for functions of complex values with complex coefficients. READ MORE

  3. 2. The impact of nicotine consumption on driving safety risk of truck drivers - with sleep quality as a mediating variable

    University essay from Lunds universitet/Institutionen för tjänstevetenskap

    Author : Ping He; Alban Xhafa; [2022]
    Keywords : truck driver; nicotine consumption; sleep quality; driving safety; sustainable supply chain; Social Sciences;

    Abstract : Introduction and aim: From a sustainable supply chain standpoint, concern for workers' safety on the job is essential. Driving safety is vital since accidents in the trucking industry often result in the deaths of both truck drivers and other road users. READ MORE

  6. 5. Many-body-based DFT treatment of fermions in optical lattices

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Jérémie Westergren; [2017]
    Keywords : DFT; density functional theory; MBA; many-body approximations; Hubbard model; Ultra cold atoms; cold atoms; optical lattice; Physics and Astronomy;

    Abstract : With recent advances in the field of ultra cold atoms one can, by trapping atoms at low temperatures by laser beams, simulate systems which can be adequately described by single-band lattice Hamiltonians. Also, due to the high parameter tunability of the experimental setups, lattice disorder can be introduced in a con- trolled fashion in these systems. READ MORE
