Robust, spatially scanning, open-path TDLAS hygrometer using retro-reflective foils for fast tomographic 2-D water vapor concentration field measurements [PDF]
Atmospheric Measurement Techniques, 2015 We have developed a fast, spatially scanning direct tunable diode laser absorption spectrometer (dTDLAS) that combines four polygon-mirror based scanning units with low-cost retro-reflective foils.

Geodesic Flows Modelled by Expansive Flows
Proceedings of the Edinburgh Mathematical Society, 2018 AbstractGiven a smooth compact surface without focal points and of higher genus, it is shown that its geodesic flow is semi-conjugate to a continuous expansive flow with a local product structure such that the semi-conjugation preserves time parametrization. It is concluded that the geodesic flow has a unique measure of maximal entropy.

Saving energy in turbulent flows with unsteady pumping
Scientific Reports, 2023 Viscous dissipation causes significant energy losses in fluid flows; in ducts, laminar flows provide the minimum resistance to the motion, whereas turbulence substantially increases the friction at the wall and the consequent energy requirements for ...

Nonclassical stochastic flows and continuous products
, 2004 Contrary to the classical wisdom, processes with independent values (defined properly) are much more diverse than white noise combined with Poisson point processes, and product systems are much more diverse than Fock spaces.

Dense bidisperse suspensions under non-homogeneous shear
Scientific Reports, 2023 We study the rheological behaviour of bidisperse suspensions in three dimensions under a non-uniform shear flow, made by the superimposition of a linear shear and a sinusoidal disturbance.

Scaling‐down biopharmaceutical production processes via a single multi‐compartment bioreactor (SMCB)
Engineering in Life Sciences, 2023 Biopharmaceutical production processes often use mammalian cells in bioreactors larger than 10,000 L, where gradients of shear stress, substrate, dissolved oxygen and carbon dioxide, and pH are likely to occur. As former tissue cells, producer cell lines
