  1. 1. Dynamic Covariance Modelling Using Generalised Wishart Processes

    University essay from Lunds universitet/Matematisk statistik

    Author : Fredrik Nilsson; [2023]
    Keywords : Covariance matrix; generalised Wishart process; Bayesian inference; Markov chain Monte Carlo; Hamiltonian Monte Carlo; Mathematics and Statistics;

    Abstract : Modern portfolio theory was pioneered by Markowitz who formulated the mean-variance problem, without which any discussion on quantitative approaches to portfolio selection would be incomplete. The framework boils down to finding the expected return $\mu$ and covariance $\Sigma$, after which the solution is proportional to $\Sigma^{-1}\mu$. READ MORE

  3. 2. DESIGN, MODELLING AND CONTROL OF A THRUST BASED UAV

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Enrico Giacomini; [2021]
    Keywords : ;

    Abstract : The current year, 2021, started with the landing of the Perseverance mission and the flight of the first drone on Mars, marking an important event in the history of space exploration. The exploration of new environments would be easier and characterised by the absence of various obstacles if implementing a larger use of drones. READ MORE

  4. 3. Implementation and comparison of the Aircraft Intent Description Language and point-mass Non-Linear Dynamic Inversion approach to aircraft modelling in Modelica

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Arcot Manjunath Shreepal; Shree Harsha Vijaya Kumar; [2021]
    Keywords : aircraft Modelling; Modelling and Simulation; Aircraft Intent; model-based systems engineering; Flight dynamics; Longitudinal stability; Aircraft Modelling; Non-linear Dynamic Inversion; Conceptual aircraft design; Dynamic Inversion; control methods; aircraft plant model; Object-oriented aircraft model; Air traffic management; Modelica; Modelon Impact; Modelica tool; 3DoF; AIDL; point-mass model;

    Abstract : The study is conducted to determine practical modelling and simulation techniques to perform dynamic stability and performance analysis on a 3 Degrees of freedom aircraft model using a Modelica-based commercial tool called Modelon Impact. This study is based on a conceptual aircraft model where in-depth details about the aircraft configuration are unknown and the aim is to determine a suitable model that can capture the longitudinal dynamics and aerodynamic constraints of the aircraft during the conceptual design phase.

  5. 4. Dynamic Performance Analysis of a Fighter Jet with Nonlinear Dynamic Inversion

    University essay from KTH/Flygdynamik

    Author : Boban Pavlovic; [2019]
    Keywords : ;

    Abstract : A modern view of aircraft performance analysis, is to quantify aircraft manoeuvrability with agility metrics. There are several different agility metrics, which can be seen as indexing of the aircraft agility performance. The quantified unit is the time it takes for the aircraft to perform a specific manoeuvre relevant to a given agility metric. READ MORE

  6. 5. Virtual Crank Angle based Cylinder Pressure Sensor

    University essay from KTH/Förbränningsmotorteknik

    Author : Christopher Ringström; [2017]
    Keywords : virtual sensor; in-cylinder pressure; heat release; wiebe parametrisation; indicated work; virtuell sensor; cylindertryck; värmeavgivning; wiebe anpassning; indikerat arbete; diesel motor;

    Abstract : Closed-loop combustion control is an on-going field of research for improving reducing engine emissions and increasing efficiency. Cylinder pressure is a key parameter to monitor for combustion feedback. READ MORE
