Current packet-switched networks such as the Internet do not provide guaranteed performance measures such as maximum loss rate or delay jitter. One way to support packet audio in these networks is to use control mechanisms which adapt the audio coding and decoding processes based on the state of the network so as to maximize the quality of the audio delivered to the destinations. This quality e...

In this article, we construct the canonical semipositive current or the canonical measure (= the potential of the canonical semipositive current) on a smooth projective variety of nonnegative Kodaira dimension in terms of a dynamical system of Bergman kernels. This current is considered to be a generalization of a Kähler-Einstein metric and coincides the one considered independently by J. Song ...

Wireless intra-body networks of implantable biomedical devices have the potential to enable revolutionary healthcare and clinical applications. In our previous work we investigated the use of ultrasonic waves as an alternative to radio frequency (RF) waves as physical carrier of information, and proposed Ultrasonic WideBand (UsWB), the first ultrasonic integrated physical and medium access cont...

The problem of robust adaptive stabilization of a class of multi-input multi-output nonlinear systems with constant linearly parameterized uncertainty and unknown structure of bounded variation have been considered. With the aid of direct adaptive technique and control Lyapunov function method, a robust adaptive controller is designed to complete the globally adaptive stability of the closed-lo...

We consider an ergodic stochastic control problem for a class of one-dimensional Itô processes where the available control is an added bounded variation process. The corresponding infinite horizon discounted control problem is solved in [28]. Here, we show that, as the discount factor approaches zero, the optimal strategies derived in [28] “converge” to an optimal strategy for the ergodic contr...
