Julius Julius, King's College Excited States of One Dimensional Defect CFTs: A Quantum Spectral Curve Approach

Here we add a driving force to the oscillator and consider how the standard form of the equation is modified. We look at the amplification factor and see what happens under resonant conditions.

We extend the ideas from the first part of the lecture to oscillators which include damping effects. Writing the governing equation in a standard form and looking at the meaning of the damping…

Here we look at how the the same (or a very similar) differential equation applies to several different engineering problems. We consider cantilevers, pendulums and a floating buoy.

Here we look at some more general oscillators and their phase portraits and consider how plotting vector plots can be useful for understanding autonomous systems.

How do understand the behaviour of the oscillator, why is plotting velocity against displacement useful? What are stationary points and limit cycles?

A look at the behaviour of the van der pol oscillator and its solution using the Runge-Kutta integrator

In the last part of the lecture we look at real numerical methods that can be used for real engineering problems. Looking briefly at Runge-Kutta methods and an application modelling methane-air…

In this part of the lecture we look at how state-space models can be used to solve higher order differential equations using the method for systems of equations.

In this lecture we look at how the numerical methods can be extended to deal with systems of equations.

When an analytical solution cannot be found, we can use a numerical method to find an approximate solution. In this lecture we look at Euler's method and explore how it can be used to solver…

What happens when the method in the first part of the lecture fails. We look at why and find a way of dealing with the problem.

In the second part of this lecture we look at how equations with a complicated right hand side is handled.
