  1. 1. The Henstock–Kurzweil Integral

    University essay from Linköpings universitet/Matematik och tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Manolis David; [2020]
    Keywords : Henstock–Kurzweil integral; generalized Riemann integral; gauge integral; Denjoy–Perron integral; narrow Denjoy integral; Perron integral; non-absolute integration; Lebesgue outer measure; absolute integrability; fundamental theorem of calculus; convergence theorems; single variable calculus;

    Abstract : Since the introduction of the Riemann integral in the middle of the nineteenth century, integration theory has been subject to significant breakthroughs on a relatively frequent basis. We have now reached a point where integration theory has been thoroughly researched to a point where one has to delve quite deep into a particular subject in order to encounter open conjectures.

  3. 2. The Dissipating Energy Flow method for analysing generator contribution to power system damping -- evaluation and interpretation

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Hampus Möller; [2019]
    Keywords : Electromechanical oscillations; small-signal stability; energy flow; PMU measurements; forced oscillations; dissipating energy.; Technology and Engineering;

    Abstract : Electromechanical oscillations is a power system phenomenon where generator rotors oscillate, leading to oscillatory power flows. Damping of such oscillations is important for system stability. Forced oscillations is a special case where one faulty component is the source of the oscillation. READ MORE

  4. 3. Basic quantisation rules of semiclassical analysis

    University essay from Uppsala universitet/Analys och sannolikhetsteori

    Author : Anders Israelsson; [2016]
    Keywords : Semiclassical analysis; Gårding inequality; Borel Theorem; Kohn-Nirenberg; Weyl; Quantization; Symbol; Asympotic expansion; Schwartz space; Tempered distribution; Pseudodifferential operator; Fourier transform; Stationary phase; Microlocal analysis; Oscillatory integral; Poisson Bracket; Lie Bracket;

    Abstract : Semiclassical analysis is the study of how to connect classical mechanics with quantummechanics in a mathematically rigorous way. What is crucial for quantum mechanics isthat the operators that occur are self-adjoint and map a subset of L2 into L2. This hasbeen proven in this thesis. READ MORE

  5. 4. Control of Unmanned Aerial Vehicles using Non-linear Dynamic Inversion

    University essay from Institutionen för systemteknik

    Author : Mia Karlsson; [2002]
    Keywords : Reglerteknik; Non-linear Dynamic Inversion; exact linearization; cascaded structure; integral action; flight control; Unmanned Aerial Vehicles; Reglerteknik;

    Abstract : This master's thesis deals with the control design method called Non-linear Dynamic Inversion (NDI) and how it can be applied to Unmanned Aerial Vehicles (UAVs). In this thesis, simulations are conducted using a model for the unmanned aerial vehicle SHARC (Swedish Highly Advanced Research Configuration), which Saab AB is developing. READ MORE
