New methods for estimation, modeling and validation of dynamical systems using automatic differentiation
(Texas A&M University, 2005-02-17)
The main objective of this work is to demonstrate some new computational methods
for estimation, optimization and modeling of dynamical systems that use automatic
differentiation. Particular focus will be upon dynamical ...
Modeling, Optimization and Testing for Analog/Mixed-Signal Circuits in Deeply Scaled CMOS Technologies
(2011-02-22)
As CMOS technologies move to sub-100nm regions, the design and verification
for analog/mixed-signal circuits become more and more difficult due to the problems
including the decrease of transconductance, severe gate leakage ...
The use of different nutritional strategies and mathematical models to improve production efficiency, profitability, and carcass quality of feedlot cattle
(Texas A&M University, 2007-04-25)
Forty eight crossbred steers (BW = 296 ñ 16.7 kg) were fed four dietary
treatments for 56 d: AL-LS (low starch diet fed ad libitum for a rate of gain of 1 kg/d),
AL-HS (high starch diet fed ad libitum), LF-HS (a limit ...
Methodology for designing the fuzzy resolver for a radial distribution system fault locator
(Texas A&M University, 2006-04-12)
The Power System Automation Lab at Texas A&M University developed a fault location scheme that can be used for radial distribution systems. When a fault occurs, the scheme executes three stages. In the first stage, all ...
Turbulent Flow and Transport Modeling by Long Waves and Currents
(2010-10-12)
This dissertation presents models for turbulent flow and transport by currents
and long waves in large domain.
From the Navier-Stokes equations, a fully nonlinear depth-integrated equation
model for weakly dispersive, ...
Imaging and Computational Methods for Exploring Sub-cellular Anatomy
(2010-01-16)
The ability to create large-scale high-resolution models of biological tissue provides an
excellent opportunity for expanding our understanding of tissue structure and function.
This is particularly important for brain ...
Selected problems in turbulence theory and modeling
(Texas A&M University, 2004-09-30)
Three different topics of turbulence research that cover modeling, theory and model computation categories are selected and studied in depth. In the first topic, "velocity gradient dynamics in turbulence" (modeling), the ...
Conversion of methanol to light olefins on SAPO-34: kinetic modeling and reactor design
(Texas A&M University, 2005-02-17)
In this work, the reaction scheme of the MTO process was written in terms of elementary steps and generated by means of a computer algorithm characterizing the various species by vectors and Boolean relation matrices. The ...
Bacterial total maximum daily load (TMDL): development and evaluation of a new classification scheme for impaired waterbodies of Texas
(Texas A&M University, 2005-02-17)
Under the Clean Water Act (CWA) program the Texas Commission on Environmental Quality (TCEQ) listed 110 stream segments with pathogenic bacteria impairment in 2000. The current study was conducted to characterize the ...
Reliability-yield allocation for semiconductor integrated circuits: modeling and optimization
(Texas A&M University, 2005-11-01)
This research develops yield and reliability models for fault-tolerant semiconductor integrated circuits and develops optimization algorithms that can be directly applied to these models. Since defects cause failures in ...
