Experimental characterisation of bubbly flow using MRI
(University of CambridgeDepartment of Chemical Engineering and BiotechnologyTrinity College, 2011-11-08)
This thesis describes the first application of ultra-fast magnetic resonance imaging (MRI) towards the characterisation of bubbly flow systems. The principle goal of this study is to provide a hydrodynamic characterisation ...
Distributed virtual environment scalability and security
(University of CambridgeFaculty of Computer Science and TechnologyComputer LaboratoryMicrosoft Research Cambridge, 2011-11-08)
Distributed virtual environments (DVEs) have been an active area of research and engineering for more than 20 years. The most widely deployed DVEs are network games such as Quake, Halo, and World of Warcraft (WoW), with ...
Statistical models for noise-robust speech recognition
(University of CambridgeDepartment of Engineering, 2011-11-08)
A standard way of improving the robustness of speech recognition systems to noise is model compensation. This replaces a speech recogniser's distributions over clean speech by ones over noise-corrupted speech. For each ...
Jetting, In-Nozzle Meniscus Motion and Nozzle-Plate Flooding in an Industrial Drop-on-Demand Print Head
(Proc 27th Int. Conf. on Digital Printing Technologies, NIP27, 2011)
The state of the ink film at and near the nozzles of a drop-ondemand(DoD) print head during jetting has a direct impact on
printing performance and reliability. We have developed highspeed imaging apparatus and analytical ...
The effect of inkjet ink composition on rheology and jetting behaviour
(Proc 27th Int. Conf. on Digital Printing Technologies, 2011)
This work presents recent results on the way linear and non linear viscoelastic properties of the fluids affect the jetting
mechanism. Recent progress on quantitative characterising both high frequency linear (LVE) and ...
Practice, power and learning in UK recorded music companies
(University of CambridgeJudge Business SchoolSt. Catharine's College, 2011-10-11)
This thesis adopts a practice-based approach to understanding how power, knowledge and knowing intermingle in organizations to facilitate/constrain individual access to opportunities for knowing-in-practice (learning). It ...
Dependence of drop speed on nozzle diameter, viscosity and drive amplitude in drop-on-demand ink-jet printing
(Proc 27th Int. Conf. on Digital Printing Technologies, NIP27, 2011)
Results of recent experiments and numerical simulations are presented, which have been used to establish empirical rules for
the dependence of drop speed on nozzle diameter and drive amplitude for Newtonian and non-Newtonian ...
Inkjet printing of non-Newtonian fluids
(Proc 27th Int. Conf. on Digital Printing Technologies, NIP27, 2011)
Jet breakup is strongly affected by fluid rheology. In particular,small amounts of polymer can cause substantially different
breakup dynamics compared to a Newtonian jet, influencing in-flight fragmentation and detachment ...
Holographic Measurement of Drop-on-Demand Drops in Flight
(Proc 27th Int. Conf. on Digital Printing Technologies, NIP27, 2011)
The analysis of images of ink drops in flight can provide information about jet straightness, drop velocity and volume.
However trade-offs between field of view, optical and digital resolution and other factors such as ...
