  1. 1. Parallelization of the SDIRK and Newton’s method and analysis of a weighted norm for error estimations

    University essay from Lunds universitet/Matematik LTH och numerisk analys

    Author : Matilda Hjälle; [2016]
    Keywords : Parallel programming; Numerical analysis; Mathematics and Statistics;

    Abstract : Execution time is an important issue in the field of numerical analysis. Simulations are getting more and more complex and the execution times are rapidly increasing. In the scope of this thesis a time integration library is used to solve initial value problems. READ MORE

  2. 2. 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

  3. 3. 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

  4. 4. On numerical simulations of turbulent flows subjected to system rotation

    University essay from KTH/Mekanik

    Author : Erik Stenberg; [2016]
    Keywords : ;

    Abstract : Different aspects of numerical simulations of turbulent flows are assessed by considering a fully-developed turbulent channel flow that is rotating in the spanwise direction. Differences between differential and explicit algebraic Reynolds-stress models (RSMs) are investigated theoretically and numerically. READ MORE

  5. 5. Numerical Modelling of a Radial Inflow Turbine with and without Nozzle Ring at Design and Off-Design Conditions

    University essay from KTH/Energiteknik

    Author : Felippo Valentini; [2016]
    Keywords : ;

    Abstract : The design of a radial turbine working at peak efficiency over a wide range of operating conditions is nowadays an active topic of research, as this constitutes a target feature for applications on turbochargers. To this purpose many solutions have been suggested, including the use of devices for better flow guidance, namely the nozzle ring, which are reported to boost the performance of a radial turbine at both design and off-design points.
