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

(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 ...
• #### IO-Lite: A unified I/O buffering and caching system ﻿

(1997-10-27)
This paper presents the design, implementation, and evaluation ofIO-Lite, a unified I/O buffering and caching system. IO-Lite unifies all buffering and caching in the system, to the extent permitted by the hardware. In ...
• #### Ionization of Rydberg atoms by half-cycle pulses: Effect of pulse shape and rise time ﻿

(1998)
The ionization of potassium np Rydberg atoms with $n\sim388$ by pulsed unidirectional electric fields, termed half-cycle pulses (HCPs), with various well-characterized shapes (rectangular, triangular, and sawtooth) and ...
• #### Is Proflavine Exposure Associated with Disease Progression in Women with Cervical Dysplasia? A Brief Report ﻿

(2018)
Proflavine is an acridine dye used with high-resolution microendoscopy for in vivo diagnostic evaluation of cervical epithelial cells. However, there are concerns that even short-term exposure of cervical tissue to dilute ...
• #### Isolating the non-polar contributions to the intermolecular potential for water-alkane interactions ﻿

(2014)
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 ﻿

(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 ﻿

(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 ﻿

(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 ﻿

(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 ﻿

(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 ﻿

(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 ...
• #### ITD assembler: an algorithm for internal tandem duplication discovery from short-read sequencing data ﻿

(2016)
Abstract Background Detection of tandem duplication within coding exons, referred to as internal tandem duplication (ITD), remains challenging due to inefficiencies in ...
• #### Iterative Data-flow Analysis, Revisited ﻿

(2004-03-26)
The iterative algorithm is widely used to solve instances of data-flow analysis problems. The algorithm is attractive because it is easy to implement and robust in its behavior. The theory behind the algorithm shows that, ...
• #### Iterative design of l(p) digital filters ﻿

(2008)
The design of digital filters is a fundamental process in the context of digital signal processing. Being essential building blocks, digital filters are used in diverse areas ranging from medical imaging or audio and video ...
• #### Iterative Multiuser Detection and Decoding ﻿

(1998-11-20)
An iterative detection and decoding algorithm is explored for a convolutionally coded DS-CDMA system. The optimum decoding strategy is to consider the trellises of all the users simultaneously, but this has exponential ...
• #### Iterative Reweighted Algorithms for Compressive Sensing ﻿

(2008-01)
The theory of compressive sensing has shown that sparse signals can be reconstructed exactly from many fewer measurements than traditionally believed necessary. In [1], it was shown empirically that using lp minimization ...
