Election '08: A Pro-Civil Justice Presidential Platform
Many Presidential candidates claim they stand "for the little guy," but do they have a proactive policy for strengthening our civil justice system so that it works for those whom it was meant to protect? Well, we have some ideas. The Drum Major Institute's latest report, Election '08: A Pro-Civil Justice Presidential Platform, lays out common-sense policy proposals that would turn the balance of power back to regular Americans

Coupling Reduces Noise
We demonstrate how coupling nonlinear dynamical systems can reduce the
effects of noise. For simplicity we investigate noisy coupled map lattices.
Noise from different lattice nodes can diffuse across the lattice and lower the
noise level of individual nodes. We develop a theoretical model that explains
this observed noise evolution and show how the coupled dynamics can naturally
function as an averaging filter. Our numerical simulations are in excellent
agreement with the model predictions
Outer Bounds on the Admissible Source Region for Broadcast Channels with Correlated Sources
Two outer bounds on the admissible source region for broadcast channels with
correlated sources are presented: the first one is strictly tighter than the
existing outer bound by Gohari and Anantharam while the second one provides a
complete characterization of the admissible source region in the case where the
two sources are conditionally independent given the common part. These outer
bounds are deduced from the general necessary conditions established for the
lossy source broadcast problem via suitable comparisons between the virtual
broadcast channel (induced by the source and the reconstructions) and the
physical broadcast channel
On Robustness Analysis of a Dynamic Average Consensus Algorithm to Communication Delay
This paper studies the robustness of a dynamic average consensus algorithm to
communication delay over strongly connected and weight-balanced (SCWB)
digraphs. Under delay-free communication, the algorithm of interest achieves a
practical asymptotic tracking of the dynamic average of the time-varying
agents' reference signals. For this algorithm, in both its continuous-time and
discrete-time implementations, we characterize the admissible communication
delay range and study the effect of the delay on the rate of convergence and
the tracking error bound. Our study also includes establishing a relationship
between the admissible delay bound and the maximum degree of the SCWB digraphs.
We also show that for delays in the admissible bound, for static signals the
algorithms achieve perfect tracking. Moreover, when the interaction topology is
a connected undirected graph, we show that the discrete-time implementation is
guaranteed to tolerate at least one step delay. Simulations demonstrate our
results
