Acoustic Emission in a Fiber Composite Plate [chapter]

Double Percolation Transition in Superconductor-Ferromagnet Nanocomposites

2010 Physical Review Letters  
We investigate the scaling behavior near both percolation thresholds, and determine the distinct critical exponents associated with two different types of transitions.  ...  This double percolation effect, which is especially pronounced at liquid helium temperatures, is controlled by composite volume fraction and originates from the suppressed interface conduction and tunneling  ...  (a) The CrO 2 side of the transition, with p CrO 2 c ¼ 0:34, and (b) the MgB 2 side, with p MgB 2 c ¼ 0:78.  ...

Service-Oriented Systems Engineering: Modeling Services and Layered Architectures [chapter]

Manfred Broy
2003 Lecture Notes in Computer Science  
In FOCUS a component is a total behavior. In contrast, a service is a partial behavior. A layer in a layered architecture is a service with two service interfaces, an import and an export interface.  ...  Based on the FOCUS theory of distributed systems (see [Broy, Stølen 01]) that are composed of interacting components we introduce a formal model of services and layered architectures.  ...  Acknowledgements It is a pleasure to thank Andreas Rausch and Bernhard Rumpe for stimulating discussions and helpful remarks on draft versions of the manuscript.  ...

Novel Actuating System Based on a Composite of Single-Walled Carbon Nanotubes and an Ionomeric Polymer

Igor A. Levitsky, Peter T. Kanelos, William B. Euler
2003 Materials Research Society Symposium Proceedings  
SWNTs were airbrushed from a chloroform suspension onto both sides of a Nafion membrane (180 µm) and the electromechanical properties of the composite material were explored.  ...  That was explained in terms of increasing of the water dielectric constant and polymer-SWNT interface area. The possible mechanisms of the actuation in this novel composite are discussed.  ...  The actuation mechanism of this composite was described in terms of electro-osmotic water transport driven by solvated cations and charging of the double layer at the interface between Nafion and platinum  ...

2005 IEEE transactions on components and packaging technologies  
In this paper, the feasibility of using miniature heat pipes to achieve effective double-sided cooling is investigated by analyzing the complete thermal circuit associated with the power device.  ...  An additional benefit associated with double-sided cooling was a significant reduction in the spatial temperature gradients along the surface of the IPEM which would translate to lower thermally induced  ...  The experiment did not include a complete, double-sided cooling configuration; rather, the experiment was designed to measure the resistance of the heat pipe and the contact resistance associated with  ...
