Matroidal Entropy Functions: A Quartet of Theories of Information, Matroid, Design, and Coding

open access: yesEntropy, 2021
In this paper, we study the entropy functions on extreme rays of the polymatroidal region which contain a matroid, i.e., matroidal entropy functions. We introduce variable strength orthogonal arrays indexed by a connected matroid M and positive integer v

Energy and position resolution of a CdZnTe gamma-ray detector with orthogonal coplanar anodes [PDF]

open access: yes, 1999
We report on the simulation, construction and performance of prototype CZT imaging detectors employing orthogonal coplanar anodes. These detectors employ a novel electrode geometry with non-collecting anode strips in 1D and collecting anode pixels ...

Port Decoupling for Small Arrays by Means of an Eigenmode Feed Network [PDF]

open access: yes, 2008
An alternative approach to port decoupling and matching of arrays with tightly coupled elements is proposed. The method is based on the inherent decoupling effect obtained by feeding the orthogonal eigenmodes of the array.

Parametric resonances in electrostatically interacting carbon nanotube arrays [PDF]

open access: yes, 2008
We study, numerically and analytically, a model of a one-dimensional array of carbon nanotube resonators in a two-terminal configuration. The system is brought into resonance upon application of an AC-signal superimposed on a DC-bias voltage.
