    • IO-Lite: A Copy-free UNIX I/O System 

      Pai, Vivek (1997-01-11)
      Memory copy speed is known to be a significant barrier to high-speed communication. We perform an analysis of the requirements for a copy-free buffer system, develop an implementation-independent applications programming ...

      Intermolecular potential models for water and alkanes describe pure component properties fairly well, but fail to reproduce properties of water-alkane mixtures. Understanding interactions between water and non-polar molecules ...
    • Isolating the Performance Impacts of Network Interface Cards through Microbenchmarks 

      Pai, Vijay S.; Rixner, Scott; Kim, Hyong-youb (2004-06-01)
      This paper studies the impact of network interface cards (NICs) on network server performance, testing six different Gigabit Ethernet NICs. Even with all other hardware and software configurations unchanged, a network ...
    • Isotropic Seebeck coefficient of aligned single-wall carbon nanotube films 

      Fukuhara, Kengo; Ichinose, Yota; Nishidome, Hiroyuki; Yomogida, Yohei; Katsutani, Fumiya; Komatsu, Natsumi; Gao, Weilu; Kono, Junichiro; Yanagi, Kazuhiro (2018)
      How the morphology of a macroscopic assembly of nanoobjects affects its properties is a long-standing question in nanomaterials science and engineering. Here, we examine how the thermoelectric properties of a flexible thin ...
    • Issues Affecting the Synthetic Scalability of Ternary Metal Ferrite Nanoparticles 

      Morrow, Lauren; Barron, Andrew R. (2015)
      Ternary Mn-Zn ferrite (MnxZn1-xFe2O4) nanoparticles (NPs) have been prepared by the thermal decomposition of an oleate complex, sodium dodecylbenzenesulfonate (SDBS) mediated hydrazine decomposition of the chloride salts, ...
    • Issues in Instruction Scheduling 

      Schielke, Philip (1998-09-15)
      Instruction scheduling is a code reordering transformation that attempts to hide latencies present in modern day microprocessors. Current applications of these microprocessors and the microprocessors themselves present new ...
    • Issues in myoelectric teleoperation of complex artificial hands 

      Farry, Kristin Ann (1995)
      This dissertation introduces a novel method of teleoperation of complex anthropomorphic robotic hands: converting the myoelectric signal generated by an operator's muscles during movement into robot commands replicating ...
    • Issues related to data mining with self organizing maps 

      Jain, Abha (2004)
      This thesis demonstrates that the clustering by Kohonen's Self-Organizing Map algorithm (KSOM) can be significantly improved by magnification control. As a second contribution, the thesis proposes a fully automated technique ...
