ABSTRACT-This paper proposed a control scheme based on fuzzy logic for a methanol water system of bubble cap distillation column. Fuzzy rule base and Inference System of fuzzy (FIS) is planned to regulate the reflux ratio (manipulated variable) to obtain the preferred product composition (methanol) for a distillation column. Comparisons are made with conventional controller and the results conf...

The molecular composition of the postsynaptic membrane is sculpted by synaptic activity. During synaptic plasticity at excitatory synapses, numerous structural, signaling, and receptor molecules concentrate at the postsynaptic density (PSD) to regulate synaptic strength. We developed an approach that uses light to tune the abundance of specific molecules in the PSD. We used this approach to inv...

We relate behavior composition, a synthesis task studied in AI, to supervisory control theory from the discrete event systems field. In particular, we show that realizing (i.e., implementing) a target behavior module (e.g., a house surveillance system) by suitably coordinating a collection of available behaviors (e.g., automatic blinds, doors, lights, cameras, etc.) amounts to imposing a superv...

One of the great potential benefits offered by solid freeform fabrication (SFF) technology is the ability to create parts that have composition variation within them. Such local composition control (LCC) has the potential to create new classes of components. Material composition can be tailored within a component to achieve local control of properties; for example, index of refraction, electric...

in aquaculture, fishes might experience periods of food deprivation during pre-harvesting, transporting and sorting. in during starvation, some fish utilize muscle protein as a major energy source and some fish utilize primarily lipids. with respect to vital role of starvation periods on body composition, the current study was carried out for one month in autumn 2010 at research farm of isfahan...
