Design and modeling of a third generation slumping tool for X-ray telescope mirrors/
Glass sheets with high surface quality and angular resolution of 5 arcsec are in demand for the International X-Ray Observatory. Several glass flattening techniques are presented in this thesis, including a method of thermally shaping individual sheets of glass using porous mandrels as air bearings …

Impact of glass design on consumption of alcohol and non-alcoholic drinks
… drinks could thus improve population health. Glassware has the potential to moderate drinking, including how much is consumed. This thesis explores the impact of glass design on drinking behaviours in four pre- registered experiments. Study 1 investigated the effect of glass shape on total …

Experiments and numerical analysis on air bearing slumping of segmented thin-shell mirrors for X-ray telescopes
Slumping (or thermal shaping) of thin glass sheets onto high precision mandrels was used by NASA Goddard Space Flight Center to fabricate the NuSTAR telescope with success. But this process requires long thermal cycles and produces mid-range spatial frequency errors due to the anti-stick mandrel …

Mathematical modelling of unsteady tube stretching with internal channel pressurisation for fabricating electrospray ionisation emitters
… made in the design of nESI emitters, as their shape and geometry are critical to the electrospray performance and subsequent MS detection. In the actual manufacturing of these emitters through the heat and draw process, the desired geometry cannot, at present, be achieved. In particular, the …
