Exercise 8
ثبت نشده
چکیده
The objective of this exercise is to demonstrate how a steady state gain matrix, K can be calculated from a linearized state space dynamic process model. The approach used has been published by Arkun and Downs [1], and it is aimed at handling cases where integrating elements, e.g. liquid levels, are present. The dynamic approach is applied to the Tennessee Eastman process, and the relative gain (RGA), and Niederlinski index (NI) are used on the resulting gain matrix as screening tools1. This exercise demonstrates the importance of a plant's level control structure on the overall plantwide control system performance.

Antidepressant effects associated with different exercise conditions in participants with depression: a pilot study.
In this article, we examined the antidepressant influence of an 8-week-long aerobic exercise intervention in which two training parameters were manipulated: exercise frequency and group environment. Twenty-three individuals with elevated symptoms of depression were recruited in a sport and fitness facility and agreed to participate in this 8-week study. They were randomly assigned to three grou...
متن کاملThe Effect of 8 Weeks of Concurrent Training on BDNF Values of Brain Hippocampus, Cognitive Function, Blood Glucose and Insulin in Streptozotocin-Induced Diabetic Rats
Background: BDNF protein is the important neurotrophin that is involved in cognitive function. Diabetes can lead to impaired function and is a neurocognitive disorder's factor in hippocampus. Therefore, the purpose of this study was to evaluate the effect of 8 weeks of concurrent training on BDNF levels in the brain hippocampus and cognitive function of streptozotocin-induced diabetic rats. Me...
متن کاملApproach to novel functional foods for stress control 2. Microarray assessment of exercise in healthy volunteers.
DNA microarray was used to measure stress response by exercise in peripheral blood leukocytes. Aerobic exercise did not alter mRNA pattern or urinary secretion of 8-hydroxy-2'-deoxyguanosine (8-OHdG). Strenuous exercise increased urinary secretion of 8-OHdG and altered mRNA pattern in microarray. These results suggest that moderate exercise, i. e. aerobic exercise, did not show any change in 8-...
