This is the second part of a two-part paper developing and validating a structural model to describe the high rate anaerobic digestion of complex wastewater. A full-scale, two-stage hybrid up ̄ow anaerobic reactor treating pig slaughterhouse e‚uent is assessed. Parameters and hydraulics are proposed for this system and validated. Characterisation of the system indicated that in̄uent was a combina...

In order to explore the dynamic behavior and process control of reactor temperature, a modified two-phase dynamic model for gas phase propylene copolymerization in a fluidized bed reactor is developed in which the entrainment of solid particles is considered. The modified model was compared with well-mixed and two-phase models in order to investigate the dynamic modeling response. The modified ...

the effect of hydraulic retention time in a range from 1.0-5.5 days was evaluated in a laboratoryscaleanaerobic fixed bed reactor packed with a hybrid material composed of tire rubber and zeolite. underthese conditions, cod removal efficiencies varied from 28.3% to 82.1%, respectively. over the more than 6months of operation, no clogging was observed. the results obtained demonstrated that this...

An anticipatory agent [1] is a hybrid agent which is able to predict changes of itself and its environment. Such agents prove interesting [2] [3] [4] in embedded systems such mobile robots. Indeed, they combine a reactive fast layer with a cognitive layer capable to perform corrective actions to avoid undesired situations before they occur actually. We present in this paper a generic architectu...

In this paper Hybrid Direct Neural Controller (HDNC) with Linear Feedback Compensator (LFBC) has been developed. Proper initialization of neural network weights is a critical problem. This paper presents two different neural network configurations with unity and random weight initialization while using it as a direct controller and linear feedback compensator. The performances of these controll...

Early application of the simple axisymmetric mirror, requiring intermediate performance between a neutron source for materials testing Q=Pfusion/Pinput ~0.05 and pure fusion Q>10, are the hybrid applications. The Axisymmetric Mirror has attractive features as a driver for a fusion-fission hybrid system: geometrical simplicity, as well as the typical mirror features of inherently steady-state op...

In this work some complex behaviors of a controlled reverse flow reactor is presented. The control system introduces discrete events making the model an infinite dimensional hybrid system. The study is conducted through continuation techniques and brute force numerical simulations. Together with standard bifurcations like pitchfork, saddle-node and Neimark–Sacker, varying the set-point paramete...
