Due to increasing circuit densities and data throughput rates, power consumption has become a significant concern in the design and operation of high-performance packet switches. We extend the idea of Dynamic Power Management (DPM) to input queued switches, allowing operators to tradeoff power and delay in a useful way. We frame the problem as a dynamic program and solve a relaxation using techniques...
We present a distributed algorithm for optimizing the rate-reliability tradeoff in wireless networks with randomly time-varying channels. The stochastic optimization is based on wireless network utility maximization, extended to incorporate dynamics at physical layer. The proposed algorithm enables a distributed implementation. We also verify the convergence of the proposed algorithm using Stochastic...
Angularly and spectrally resolved second harmonic studies for c-axis ZnO nanorods are reported. 7.5 times higher efficiency than for BBO was found at 55 GW/cm2 at Ti:sapphire laser oscillator wavelengths. Spectral profiles agree with simulations.
This paper describes research into methods for interactive sonification of 2D image data. The method utilizes an existing device (from computer game), Nintendopsilas wiimote controller to provide a means of interaction with 2D images for the exploration and triggering of sonic response. This paper details a selection of sonification algorithms which have been designed to provide auditory display of...
