The OFEX (Optimal and Fully EXplicit) rate controller is able to provide not only the optimal bandwidth allocation but also the fully explicit congestion signal to sources. It exercises link-wise proportional fairness and network-wise max-min fairness, which enables the controller to feed the congestion signal back from the most congested link, instead of using the networkwise proportional fair...

I seek to mediate this debate. I describe a general framework for interactional models of implicature and then assess the major arguments for grammar-driven approaches. My central findings are that many of these arguments are conceptually or theoretically problematic, and that the valid ones do not compromise the Gricean picture. Stepping back, I find that the two sides in this debate are not r...

Concerns about the work of breathing imposed by the endotracheal tube have led clinicians to routinely use pressure support to overcome this resistive component. More recently, ventilator manufacturers have introduced systems to automatically overcome endotracheal tube resistance, regardless of tube diameter or patient demand for flow. Despite the theoretical advantages, neither method appears ...

Hollis The Robotics Institute, Carnegie Mellon University faquaid, [email protected] Abstract Planar linear motors (Sawyer motors) have been used in industry as open-loop stepping motors, but their robustness and versatility has been limite...

The Sort and Sift, Think Shift qualitative data analysis approach is an iterative process where analysts dive into to understand its content, dimensions, properties, then step back assess what they have learned determine next steps. Researchers move from establishing understanding of in the (“Diving In”) exploring their relationship (“Stepping Back”). This “Diving In” “Stepping Back” repeated t...

1. Abstract The objective of this paper is to report the results from the research being conducted in reconfigurable flight controls at NASA Ames. A study was conducted with three NASA Dryden test pilots to evaluate two approaches of reconfiguring an aircraft’s control system when failures occur in the control surfaces and engine. NASA Ames is investigating both a Neural Generalized Predictive ...

This paper presents the design and implementation of neural network controller for reducing torque ripples in brushlessDC (BLDC) motor drive with trapezoidal back-emf. The performances of the proposed neural networkcontroller are compared with the corresponding fuzzy PI controller and conventional PI controller. Simulation results are used to show the abilities and shortcomings of the proposed ...
