This dissertation investigates the use of a hardware mechanism called Eager Data Transfer (EDT) for achieving the reduction of communication latency for user-level network protocol. To reach the goal, the dissertation addresses the following research issues. First, the development of a communication system performance evaluation tool called Linux/SimOS is presented....
Atmospheric and surface ocean temperatures in the Antarctic Peninsula region have increased by a few degrees Celsius over the last few decades, and they are the most rapid changes recorded in the Southern Hemisphere during this time period (Cook et al., 2005; Meredith and King, 2005). Associated with this ongoing...
Delta-sigma analog-to-digital converters traditionally have been used for low speed, high resolution applications such as measurements, sensors, voice and audio systems. Through continued device scaling in CMOS technology and architectural and circuit level design innovations, they have even become popular for wideband, high dynamic range applications such as wired and...
The objective of this study was to develop a numerical model for the movement
and fate of chlorinated phenols in groundwater. In the first part, a numerical model for
several different equilibrium and nonequilibrium sorption processes under isothermal
conditions is developed for one-dimensional, steady-state water flow in soil columns.
The...
Least cost formulations for surimi seafood were studied
by linear programming (LP) and nonlinear programming (NLP).
The effects of water and starches on functional properties of
Alaska pollock and Pacific whiting surimi gels were
investigated. Six starches (modified potato starch, potato
starch, modified wheat starch, wheat starch, modified waxy corn...
Arrays of hydrophones were deployed within the Bransfield Strait and Scotia Sea (Antarctic Peninsula region) from 2005 to 2009 to record ambient ocean sound at frequencies of up to 125 and 500 Hz. Icequakes, which are broadband, short duration signals derived from fracturing of large free-floating icebergs, are a prominent...
Ever increasing global internet data traffic has driven up the demand for cutting-edge high-speed wireline communication systems including SerDes PHY for various interfaces, interconnects, data centers servers and switches in optical systems. Operating wireline communications at higher data rates leads to signals suffering from greater channel loss and exponential increase...
Adult male guinea pigs were maintained on four dietary regimens
for a period of 8 weeks. The basic diet consisted of powdered guinea
pig chow with 10% coconut oil. The three experimental groups
received the basic diet with additions of either 1% lecithin, 0.25%
cholesterol, or 0.25% cholesterol plus 1%...
The Production Switching Heuristic (PSH) developed by
Mellichamp and Love (1978) has been suggested as a more
realistic, practical and intuitively appealing approach to
aggregate production planning (APP). In this research, PSH
has been modified to present a more sophisticated open grid
search procedure for solving the APP problem. The...
