An embedded explicit Runge-Kutta-Nystrom method for solving oscillatory problems

open access: yes, 2009
A new pair of embedded explicit Runge–Kutta–Nyström (RKN) methods is developed to integrate second-order differential equations of the form q00=f(t,q) where the solution is oscillatory.

Jet heat transfer in the vicinity of a rotating grinding wheel [PDF]

open access: yes, 2005
Impinging jets are known as a method of achieving high convective heat transfer coefficients. One potential application of impinging jet heat transfer is the air jet cooling of a grinding process. A grinding process generates heat that must be dissipated

On the Analysis Dependence of DESI Dynamical Dark Energy

open access: yes
We continue scientific scrutiny of the DESI dynamical dark energy (DE) claim by explicitly demonstrating that the result depends on the analysis pipeline. Concretely, we define a likelihood that converts the w0waCDM model back into the (flat) ΛCDM model,
