Current and future high-contrast imaging instruments require extreme adaptive optics systems to reach contrasts necessary directly imaged exoplanets. Telescope vibrations the temporal error induced by latency of control loop limit performance these systems. One way reduce effects is use predictive control. We describe how model-free reinforcement learning can be used optimize a recurrent neural...

Objective: Type 2 diabetes mellitus (T2DM) is a chronic condition that requires consistent medical care to help control glycemic indices. Diabetes self-management is found to be essential for optimal glycemic control. This study aimed to investigate the predictors of diabetes self-management in adult with T2DM. Materials and Methods: A cross-sectional study was conducted. A purposive sample of...

the purpose of the present study is to examine the effects of ego depletion on arousal of elite iranian swimmers. the sample comprised elite swimmers invited to the national swimming team as focused and semi focused (36 subjects). the research design was as pre- and post-test—in two phases of ego depletion conditions and the lack of ego depletion conditions in two experimental and control group...

This work builds on our prior results to develop novel control structure design principles for integrated plants featuring multiple time scale dynamics. Specifically, the concept of self-optimizing control can be used to identify the variables that must be controlled to achieve acceptable economic performance during plant operation. This approach does not, however, provide guidelines on control...

A case study of a waste incineration plant operating close to optimality by using simple feed-back control schemes is presented. Using off-line optimization the structure of the optimization problem is exploited and a set of variables is found, such that if the process is controlled with those variables are at their setpoints, operation is near-optimal. The procedure applied to the waste incine...

A heat-integrated prefractionator arrangement is studied for a ternary separation of a propane-butanepentane mixture. These types of integrated prefractionator arrangements have large energy savings compared with the best of the direct or indirect sequence with no heat integration. However, a heatintegrated distillation system can be more difficult to control than a non-integrated arrangement, ...

In tension systems, the main concern is to decouple the tension and velocity in spite of radius variations and other perturbations. To solve this control problem and design the optimal controller, this paper develops a mixed-sensitivity robust H∞ control based on self-optimizing algorithm. First, the modeling of the tension system is presented with relative theorems. Second, a mixed-sensitivity...
