10 Jan 2024: b) Start again, but this time formulate the model for RBC count as a delay differential equation forR(t), where the production of new cells is proportional to R(t T).

8 Mar 2024: ii) In the case k > 0, we define a new time coordinate η bydη. ... Deduce that if fα is chosen to satisfyfα = hαβ,β, then in the new coordinates the gauge condition hαβ,β = 0 holds.

5 Jan 2024: All positions in the new frame are related to positions in the old frame byx′ = f(x, t). ... Consider, in particular,the transformations (a) – (c) listed below. In each case obtain an equation for mẍ′(t′).Note that ′ denotes the new frame and

31 Jan 2024: Show that, by changing to a new parameter λ(µ), any geodesic can be affinely parametrized.

29 Feb 2024: z z′ =(z3 z2)(z z1). (z3 z1)(z z2). that the new differential equation is of the same form but now with regular singular points at0, 1, with the same

4 Jan 2024: Find a gauge transformation such that the new vector potential is ‘transversely polarized’,i.e.

18 Jun 2024: As demonstrated with computational examples, the new algorithms yield a library of new methods. ... Comparisons are made with elastic boundary element methods, where the new method is found to be faster and more accurate.
