This talk considers the distributed estimation problem of a linear stochastic system described by an autoregressive model with exogenous inputs when both the system orders and parameters are unknown. ...
A note on the order of l1-optimal compensators
Information Sysfems Laboratory Stanford Universiiy Slanjord, CA 94,305
2015/8/13
Recently, Dahleh and Pearson showed that when an l1 optimal compensator for a digital single-input, single-output, time-invariant plant exists, it is rational if the plant itself is. In this note, we ...
Array signal processing with robust rejection constraints via second-order cone programming
Vector and array signal processing noise the ellipsoid array robust optimization
2015/8/10
We consider the array signal processing problem of choosing the weight vector to minimize noise power, subject to a unit array gain for the desired wave, and subject to rejection constraints on interf...

On the Computation of the Higher-Order Statistics of the Channel Capacity for Amplify-and-Forward Multihop Transmission
Computation the Higher-Order Statistics the Channel Capacity Amplify-and-Forward Multihop Transmission Information Theory
2012/6/15
The latest research trends in the wireless communications and standardizations [1] accentuate that the higher-order statistics (HOS) of the channel capacity are necessary to achieve a reliable and tru...
Cluster Synchrony in Systems of Coupled Phase Oscillators with Higher-Order Coupling
Cluster Synchrony Coupled Phase Oscillators Higher-Order Coupling
2011/9/29
Abstract: We study the phenomenon of cluster synchrony that occurs in ensembles of coupled phase oscillators when higher-order modes dominate the coupling between oscillators. For the first time, we d...
The Biological Metaphor of a Second-Order Observer and the Sociological Discourse
sociocy bernetics meaning observer social systems observational report expectation communication
2010/4/8
Purpose: In the tradition of Spencer Brown's (1969) Laws of Form, observation was defined in Luhmann's (1984) social systems theory as the designation of a distinction. In the sociological design, how...

2007/12/17
The problem of existence or non-existence of singular cycles (or komoclinic loops and keteroclinic cydes as being termed in the modern literature of nonlinear dyndric systems) is one of the most impor...
