Typical production objectives in distillation process require the delivery of products whose compositions meet certain specifications. The distillation control system, therefore, must hold product compositions as near the set points as possible in faces of upset. In this project, inferential model predictive control, that utilizes an artificial neural network estimator and model predictive cont...

In this paper, reinforcement learning algorithms are applied to a foraging task, expressed as a control composition problem. The domain used is a simulated world in which a variety of creatures (agents) live and interact, reacting to stimuli and to each other. In such dynamic, uncertain environments , fast adaptation is important, and there is a need for new architectures that facilitate on-lin...

This chapter deals with modelling and control of discrete event systems. Discrete event systems (DES) are event driven man made systems whose evolution is guided by occurrences of asynchronous events as opposed to classical time driven discrete or continuous systems. DES are modelled by tools from computer science like automata, Petri nets and process algebras. There are two major streams in co...

Overweight appears when persistent positive energy imbalances occur for long periods of time. Knowledge of dietary risk factors during childhood and adolescence is needed in order to design preventive measures against the increase in the prevalence of obesity and its consequences but is, however, largely missing. Longitudinal studies in children have not found clear causal associations between ...

copper extraction from heap 3 low grade ore at sarchechmeh is limited due to its mixed composition (copper oxide and sulphide minerals). changing this heap to a bioheap could improve the copper recovery.

some researches made in the field of agency problem issue, deal with the role of control systems regarding owners and managers. in this research the relationship between the two control mechanisms, namely the voluntary disclosure (external control mechanism) and outside directors (internal control mechanism), which are reductive of agency problems, has been studied. for this reason, a sample ...

Background and purpose: Obesity is one of the health problems, which is a risk factor for cardiovascular diseases. Many studies investigated the effects of using whole body vibration (WBV (with other methods on body composition. However, no study has examined the effect of WBV alone on body composition. The aim of this study was to compare the effects of WBV with exercise and WBV alone on body ...

Self-managed systems are essentially closed loop control systems. When designing such systems we should ensure that they do not allow fundamentally bad properties, too slow convergence, oscillation, chaotic behaviour, stuck modes; just as for any control system. How can we perform these checks in the presence of arbitrary (Turing complete) control functions? We argue that the space of control f...
