Neonatal nursing has always been my passion and to return to my roots in Samoa in 2008 to share my knowledge and skills was both a privilege and a challenge. It had taken me seven years to find the right contacts to introduce the bubble continuous positive airway pressure (BCPAP) nasal breathing system to the Tupua Tamasese Meaole (TTM) Hospital’s neonatal intensive care unit (NICU) in Apia. Th...

Because of persistent economic pressure on cost reduction, inorganic fillers such as precipitated calcium carbonate (PCC) have become increasingly economically attractive in the papermaking process. The increase of filler level in paper can be achieved by adding it to pulp prior to the headbox, either as individual filler particles or as preaggregates, while maintaining paper strength and minim...

This thesis presents a practical approach to model based control of nonlinear dynamical systems using multilayered perceptron type neural networks as process models and controllers. A framework for modeling and identification of nonlinear time series models is introduced. Advanced parameter estimation methods are used to identify the weights of the process model and controller networks. A novel...

The UCLH Mark 1b is a portable EIT system that can address up to 64 electrodes, which has been designed for imaging brain function with scalp electrodes. It employs a single impedance-measuring circuit and multiplexer so that electrode combinations may be addressed flexibly using software. It operates in the relatively low frequency band between 225 Hz and 77 kHz, as lower frequencies produce l...
