  1. 1. Nonlinear Approximative Explicit Model Predictive Control Through Neural Networks : Characterizing Architectures and Training Behavior

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tobias Bolin; [2019]
    Keywords : ;

    Abstract : Model predictive control (MPC) is a paradigm within automatic control notable for its ability to handle constraints. This ability come at the cost of high computational demand, which until recently has limited use of MPC to slow systems. READ MORE

  2. 2. The effect of financial liberalization on economic growth: A panel data analysis of 38 countries

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Shufei Zhang; [2019]
    Keywords : Financial deepening theory; Financial liberalization; Economic growth; Panel data model; Business and Economics;

    Abstract : This paper empirically surveys the actual links between financial liberalization and economic growth by drawing lessons from both developed and emerging economies over 26 years. The macroeconomic indicators for economic growth are GDP per capita growth, growth volatility, and real lending interest rate. READ MORE

  4. 4. An introduction to some ordinary differential equations governing stellar structures

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Yani di Giovanni; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : The Lane-Emden equation is a non-linear differential equation governing the equilibrium of polytropic stationary self-gravitating, spherically symmetric star models; $${\frac {1}{\xi ^{2}}}{\frac {d}{d\xi }}\left({\xi ^{2}{\frac {d\theta }{d\xi }}}\right)+\theta ^{n}=0.$$ In the isothermal cases we have the Chandrasekhar equation: $${\frac {1}{\xi ^{2}}}{\frac {d}{d\xi }}\left({\xi ^{2}{\frac {d\psi}{d\xi }}}\right)-e^{-\psi}=0$$ After having derived these models, we will go through all cases for which analytic solutions are achievable.

  5. 5. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Axel Elfving; [2019]
    Keywords : frequency resolved optical gating; optical parametric amplification; difference frequency generation; nonlinear optics; laser pulse compression; lasers; optics; Technology and Engineering; Physics and Astronomy;

    Abstract : This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. READ MORE
