Multiplexed superconducting quantum interference device (SQUID) amplifiers have recently enabled the deployment of kilopixel arrays of superconducting transition-edge sensor (TES) detectors on a variety of receivers for astrophysics. Existing multiplexing

Little Things Mean a Lot: Water and the Adhesive Bond

February 21, 2010
Author(s)
Donald L. Hunston, Kar T. Tan, Bryan D. Vogt, Sushil K. Satija, Cyril Clerici, David E. White
The ability of water to dramatically weaken many types of adhesive bonds has been widely studied. One surprising result is the existence of a critical moisture level in the bond. Above this level the strength drops to very low values. Numerous studies have

Roles of Adhesive and Interfacial Properties on Humidity-induced Failure

February 21, 2010
Author(s)
Kar T. Tan, Christopher C. White, Donald L. Hunston, Kristen L. Steffens, Hatlee Timothy, Kristen Hamilton, Vogt D. Bryan
Adhesion loss due to moisture is a fundamental problem in a large diversity of industries ranging from microelectronics and automotive to aerospace. This study investigates the durability of model adhesive joints consisting of a homologous series of poly(n

Melting and Spread of Polymers in Fire with the Particle Finite Element Method

February 19, 2010
Author(s)
Eugenio Onate, Riccardo Rossi, Sergio R. Idelsohn, Kathryn Butler
A new computational procedure for analysis of the melting and flame spread of polymers under fire conditions is presented. The method, termed Particle Finite Element Method (PFEM), combines concepts from particle-based techniques with those of the standard
