Hypoxic Incubation Chamber
… design, manufacturing, and testing of a novel controllable hypoxic incubator with fully functional oxygen gas control and temperature control in a humid environment. On the current market, a majority of the few hypoxic incubators use pre-mixed gas that does not offer precise control over gas …

GASMAK2 model for longwall gob gas emission
… and improvement of an empirical model---GASMAK2, that describes methane control requirements for the longwalling coal in gassy areas. This is not a theoretical model; it uses an empirically determined gas emission rate as an input. The computer program divides Longwall panels into …

Dual fuel conversion of a direct-injection diesel engine
Dual fuel pilot-injected diesel natural gas engines offer significant potential to reduce oxides of nitrogen (NOx) and particulate matter (PK emissions while maintaining diesel-like efficiency. A 1994 Navistar T444E turbocharger V-8 diesel engine was converted to dual fuel diesel and compressed …

The monitoring and control of specialist ceramic kiln atmospheres and emissions.
… were reproduced using a 100 litre down draft gas kiln designed and constructed for the purpose. A 40 litre electric kiln was modified for use with reducing atmospheres and a laboratory muffle kiln was also adapted to provide closely controlled firing conditions. Alternative reducing …

External field effects on electronic and ionic defects in functional oxides: Experiments and simulations
… impedance measurement on one sample under controlled temperature and atmosphere. This approach can access a wide temperature range (room temperature to 700℃) and maintain precise gas control (oxygen partial pressure down to 1-10 ppm without reactive gas) relevant to mixed ionic-electronic …

Ensemble control of robotic systems
… dissertation, we apply the framework of ensemble control theory to derive an approximate steering algorithm for two classical robotic systems---the nonholonomic unicycle and the plate-ball manipulator---in the presence of model perturbation that scales all inputs by an unknown but bounded …
