We address the problem of finding an optimal feedback control for feeding a fed-batch bioreactor with one species and one substrate, from a given initial condition to a given target value in a minimal amount of time. Mortality rate for the biomass and nutrient recycling are taken into account in this work. The optimal synthesis (optimal feeding strategy) has been obtained by Moreno in 1999 when...

OBJECTIVE We determined the standardized mortality ratio (SMR) in our anorexia nervosa (AN) patient population. METHOD We used a cross-sectional design to study an inception cohort (1981-2000) drawn from the provincial tertiary care eating disorders program at St. Paul's Hospital (British Columbia, Canada). All patients who completed their initial assessment for an eating disorder were includ...

aim : the aim of this study is to estimate gastric cancer (gc) mortality rate for iranian population, using bayesian approach in order to revise the existing classification which is thought to be a misclassification. background : gastric cancer (gc) is an important cause of mortality among many other types of cancer. data on cancer mortality can be used to guide policy makers in order to setup ...

Despite previous studies indication that Myocardial Infarction mortality rate decreases considerable after treatment, evidences point to the fact that decrease in mortality rate is only short time of thirty day duration and there is no significant change in long term mortality rate of myocardial infarction incident patients. Any significant change in the long-term mortality rate of one year to ...
