    • Multiple-User Quantum Optical Communication 

      Yen, Brent J. (2004-10-07)
      A fundamental understanding of the information carrying capacity of optical channels requires the signal and physical channel to be modeled quantum mechanically. This thesis considers the problems of distributing multi-party ...
    • An Ultra-Low-Power Programmable Analog Bionic Ear Processor 

      Sarpeshkar, Rahul; Salthouse, Christopher; Sit, Ji-Jon; Baker, Michael; Zhak, Serhii; e.a. (2004-09-28)
      We report a programmable analog bionic ear (cochlear implant) processor in a 1.5µm BiCMOS technology with a power consumption of 211µW and 77dB dynamic range of operation. The 9.58mm x 9.23mm processor chip runs on a 2.8V ...
    • Bipolar Thermoelectric Devices 

      Pipe, Kevin Patrick (2004-09-28)
      The work presented here is a theoretical and experimental study of heat production and transport in bipolar electrical devices, with detailed treatment of thermoelectric effects. Both homojunction and heterojunction ...
