This work explores the use of a model-based control scheme to enhance the productivity of polyhroxyalkanoate (PHA) production in a mixed culture two-stage system fed with synthetic wastewater. The controller supplies pulses of substrate while regulating the dissolved oxygen (DO) concentration and uses the data to fit a dynamic mathematical model, which in(More)
Since appearance of fatigue is a reality in rehabilitation sessions, developing a muscle model that is able to cope with this effect in dynamic contractions is a must. In this paper we attempt to model the effect of fatigue in a Hill type muscle model with weighting sum of joint torques. The promising results will contribute to achieving a generalized model(More)
UNLABELLED Fast Track surgery is designed to optimize time in low-complexity procedures, thus improving efficiency in care provision, and preserving patient safety. METHOD Before and after intervention study in a surgical setting, with failure mode and effects analysis, identification and prioritization of improvement opportunities, process measurement(More)
A probabilistic geometric model for D image line seg ments is rst presented We then propose a method using D segments to accumulate evidence along an image sequence of a polyhedral scene The proposed method degrades gracefully with camera location noise The matched D segments are fused with an extended Kalman lter to reconstruct the scene structure The(More)
