  1. 1. Nonradial Solutions of a Nonlinear Elliptic Equation

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Sebastian Andersson; [2017]
    Keywords : Mathematics and Statistics;

    Abstract : We consider the partial differential equation ∆u + f(u) = 0 in two dimensions,where f is a nonlinear function of u. Under certain assumptions on f we show that the equation has non-radial C² solutions with u(x) → 0 as |x| → 0 with an arbitrary number of zeros on each axis. READ MORE

  2. 2. Two variational problems related to the nonlinear Schrödinger equation

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Oscar Stolpe; [2017]
    Keywords : Nonlinear Schrödinger equation; Standing waves; Bose-Einstein condensate; Variational problem; Elliptic functions; Mathematics and Statistics;

    Abstract : The nonlinear Schrödinger equation is a partial differential equation which appears as a model in several branches of physics, including Bose-Einstein condensation and hydrodynamics. In this thesis, we investigate a particular class of solutions, namely periodic standing waves. READ MORE

  3. 3. An Optimal Control Toolbox for MATLAB Based on CasADi

    University essay from Linköpings universitet/Fordonssystem

    Author : Viktor Leek; [2016]
    Keywords : Optimal Control Direct Collocation Multiple Shooting Casadi Matlab Hybrid Vehicle;

    Abstract : Many engineering problems are naturally posed as optimal control problems. It may involve moving between two points in the fastest possible way, or to put a satellite into orbit with minimum energy consumption. Many optimal control problems are too difficult to be solved analytically and therefore require the use of numerical methods. READ MORE

  4. 4. Aircraft antenna array for seamless direct air-to-ground communication system

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Anton Gusarov; [2016]
    Keywords : ;

    Abstract : Today, data communication provided for passengers on board of commercial airliners is significantly limited and mostly relies on satellite systems. One of the solutions for this problem is a direct air-to-ground communication systems (DA2GC) able to provide much larger data throughput in a seamless manner. READ MORE

  5. 5. Reliable communication in mine environments for autonomous vehicles

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Alessandro Tomasi; [2016]
    Keywords : vehicular communication; intelligent transport system; 802.11p; autonomous mining;

    Abstract : Automation in the mining industry has the potential to increase safety and productivity while improving working conditions. Ore transportation within the mine is a repetitive task which is well suited to be replaced by an autonomous mining vehicle operating around the clock. READ MORE
