Applications of nonautonomous infinite-dimensional systems control theory for parabolic PDEs
DownloadFall 2013
Parabolic partial differential equations (PDEs) are used as models of transport-reaction phenomena in a variety of different industrial chemical and materials engineering processes, and can yield precise descriptions of process variables with complex temporal and spatially dependent system...

Pulses of ocean primary productivity during the fall season are frequent in the mid-latitudes when ocean cooling and wind-driven turbulence erode the surface stratification and allow the injection of nutrients into the euphotic zone. This phenomenon is often referred to as a phytoplankton fall...

Consider an open control volume consisting of a porous medium submerged in a surrounding ambient fluid of density ρa. The top and bottom of the control volume allow ambient fluid to enter the porous medium. Saline fluid of density ρs>ρa is supplied at a constant rate of Qo near the top of the...

Characterization of Particulate Emissions of Homogeneous Charge Compression Ignition Engines
DownloadFall 2013
The particle size distribution, volatility, and effective density of particulate matter are measured using a cooperative fuel research engine during motoring, spark ignition, and homogeneous charge compression ignition. For all operating modes, less than 5% of the particulate mass remains when...

Thunderstorms have the potential to produce severe weather and can result in significant financial and human losses. The province of Alberta is one of Canada’s most active thunderstorm regions, with the record for insured damage due to hail. Therefore, it is crucial that thunderstorm forecasts be...

Comparison of the open‐closed separatrix in a global magnetospheric simulation with observations: The role of the ring current
Download2010
Kabin, Konstantin, Lu, J. Y., Rankin, Robert, Gombosi, Tamas I., Watt, Clare E. J., Ridley, Aaron J., Toth, Gabor, Milan, Steve E., Zhang, Jichun, Rae, I. Johnathan, Clauer, C. Robert, De Zeeuw, Darren L., Fenrich, Frances
The development of global magnetospheric models, such as Space Weather Modeling Framework (SWMF), which can accurately reproduce and track space weather processes has high practical utility. We present an interval on 5 June 1998, where the location of the polar cap boundary, or open-closed field...

Decline and partial rebound of the Labrador Current 1993-2004: Monitoring ocean currents from altimetric and conductivity-temperature-depth data
Download2010
Chen, Nancy, Ohashi, Kyoko, Fischer, Jürgen, Myers, Paul G., Han, Guoqi, Nunes, Nuno
Monitoring and understanding of Labrador Current variability is important because it is intimately linked to the meridional overturning circulation and the marine ecosystem off northeast North America. Nevertheless, knowledge of its decadal variability is inadequate because of scarcity of current...

Effects of Negative Valve Overlap on HCCI Combustion and its use in the Control of HCCI Combustion Timing
DownloadFall 2014
Homogeneous charge compression ignition (HCCI) combustion can produce higher efficiencies and lower emissions when compared to tradition spark or compression ignition engines. This study reports an experimental investigation into the effects of valve timings on HCCI combustion conditions. Using a...

Fall 2012
An experimental single cylinder engine with variable valve timing is used to study spark ignition and homogeneous charge compression ignition (HCCI). The discrete wavelet transform, on a single cylinder engine with a cam-phasing head, is used in real time for knock detection in HCCI. Classical...
