High purity distillation columns are critical unit operations in cryogenic air separation plants. The development of nonlinear control technology is motivated by the need to frequently change production rates in response to time varying utility costs. Detailed column models based on stage-by-stage balance equations are too complex to be incorporated(More)
—High purity distillation columns are critical unit operations in cryogenic air separation plants that supply purified gases to a number of industries. We have developed a nonlinear model predictive control (NMPC) strategy based on the assumption of full-state feedback for a prototypical cryogenic distillation column to allow effective operation over a wide(More)
BACKGROUND Hgb A1c levels may be higher in persons without diabetes of lower socio-economic status (SES) but evidence about this association is limited; there is therefore uncertainty about the inclusion of SES in clinical decision support tools informing the provision and frequency of Hgb A1c tests to screen for diabetes. We studied the association between(More)
and reproduction in any medium, provided the original work is properly cited. Objective This roundtable will provide a hands-on workshop to learn about three surveillance systems developed and used by the Emergency Department Syndromic Surveillance Team at KFL&A Public Health. It will be an opportunity to address issues relevant to syndromic surveillance(More)
BACKGROUND Electronic medical records (EMRs) used in primary care contain a breadth of data that can be used in public health research. Patient data from EMRs could be linked with other data sources, such as a postal code linkage with Census data, to obtain additional information on environmental determinants of health. While promising, successful linkages(More)
Lyme borreliosis, caused by the bacterium, Borrelia burgdorferi, is an emerging vector-borne infectious disease in Canada. According to the Public Health Agency of Canada (PHAC), by the year 2020, 80% of Canadians will live in Lyme endemic areas. An understanding of the association of Ixodes scapularis, the main vector of Lyme disease, with it hosts is a(More)
— Fundamental dynamic models of distillation columns are not well suited for incorporation into non-linear model predictive control schemes due to their high state dimension. We investigate two reduced order nonlinear modeling techniques for high purity distillation columns. Compartmental and nonlinear wave models developed for a nitrogen purification(More)
