The application to the controlled injection of fuel in detonation tubes for pulsed detonation engines is considered. The architecture consists of laser attenuation sensing of liquid volume fraction along the tube, actuation on the liquid injection pressure through an array of solenoidal valves, and proportional-integral feedback. The architecture is validated by means of cold-ow experiments regulating the concentration pro le of water droplets along the detonation tube to desired values.

We abstract the contest between the attackers and the defense as a game with two sides: N-levels of security on one side and M coordinated attackers on the other. The different security systems in place, such as walk-in metal detectors or X-ray machines, or even human personnel are described by their detection rates and false alarm rates for objects inspected by them. We assume that the M attackers share all of their knowledge through perfect communication. Under these conditions we derive the optimal strategies for both the security system and the criminals for static detection thresholds of the security devices; under conditions of randomization of the detection thresholds; and for certain kinds of feedback when an attacker is caught. Our results show that current security levels can be maintained at significantly lower personnel costs (up to 50%) or equivalently, the potential for attaining much higher throughput (up to 200%) without any changes to hardware, and with little change to personnel training.

We show, in special cases in which there exists a partial knowledge of parameter values, proofs of global and exponential convergence of both the tracking and parameter tracking errors. We then extend the proposed method from first order systems to linear systems

We first show the benefits of pure hedging, hedging when the facility has its own power source-we consider the use of cogeneration in winter and the use of solar power in summer. We next show how active control of facility temperature set points augments the benefits of the hedging and use of local power. Our studies are based on real consumption data of a large commercial facility, the corresponding real time prices of grid power, prices of natural gas, intensity of solar radiation, and temperature history of the period under consideration. We show that the combination of hedging, local power generation and active control can reduce facility energy bills by up to 30%, and bill variance by up to 80%. Thus, we have a scenario where consumers save significantly while using power sources with a smaller carbon footprint.

The paper develops a clean analytic per-formance model characterizing a multi-hop CSMA/CA network that can be practically used for QoS provisioning. Using the analytic model developed, we propose a QoS adaptation frame-work which tunes parameters at the time of new unicast flow admission into the network. Preliminary numerical evaluations and simulation performance results demonstrate the potential throughput gain by our adaptation scheme.
