      We performed detailed photoluminescence (PL) spectroscopy studies of three different types of single-walled carbon nanotubes (SWNTs) by using samples that contain essentially only one chiral type of SWNT, (6,5), (7,5), or ...
    • Photothermal energy conversion by plasmonic nanoparticles 

      Cole, Joseph Raymond (2009)
      Photothermal energy conversion is important when designing optically active devices based on plasmonic nanoparticles. Many early applications of these nanoparticles, like photothermal tumor ablation, drug delivery, and ...
    • Physical characterization of lithium niobate thin films on silicon substrates 

      Stone, Barbara Ann (1988)
      The structure and orientation of radio frequency sputtered lithium niobate (LiNbO$\sb3$) films on silicon substrates is determined using x-ray diffraction. The structure of the LiNbO$\sb3$ films is determined to be a strong ...
    • Physical Layer Algorithm and Hardware Verification of MIMO Relays Using Cooperative Partial Detection 

      Amiri, Kiarash; Wu, Michael; Duarte, Melissa; Cavallaro, Joseph R. (2010-03-01)
      Cooperative communication with multi-antenna relays can significantly increase the reliability and speed. However, cooperative MIMO detection would impose considerable complexity overhead onto the relay if a full ...
    • Physical layer algorithms with limited feedback: Power control and coding strategies 

      Khoshnevis, Ahmad (2007)
      The uncertainty in the received signal is the main limiting factor for the throughput of any communication system with limited resources. In this thesis we analyze the potential gain in throughput by managing channel ...

      Sinclair, J.B.; Tang, J.; Varman, Peter J. (1996)
      In a shared-disk parallel I/O system, several processes may be accessing the disks concurrently. An important example is concurrent external merging arising in database management systems with multiple independent sort ...
