Global warming is an increasingly serious problem around the world. To mitigate the influence of global warming on people’s lives, the Obama Administration put an emphasis on reducing greenhouse gas (GHG) emissions to mitigate global warming. The adoption of energy efficient vehicles, including hybrid electric vehicles (HEVs), plug-in hybrid vehicles...
The present study investigated whether vitamin E supplementation reduced oxidative stress in erythrocytes and improved vitamin E status in patients undergoing hemodialysis (HD). Plasma and erythrocyte α-tocopherol, plasma ascorbic acid, and iron status were determined in 11 regular HD patients prior to and post-dialysis, before and during oral supplementation of...
The gradient of a velocity vector field is an asymmetric tensor field which can provide critical insight that is difficult to infer from traditional trajectory-based vector field visualization techniques. I describe the structures in the eigenvalue and eigenvector fields of the gradient tensor and how these structures can be used...
In order to estimate wind turbine residL2;characteristics
in the presence of atmospheric turbulence, the important atmospheric
sources for the force excitations felt by the wind turbine system
must be identified and characterized. The goal of this research
is to develop the wind turbulence input model for horizontal axis
wind turbines....
The low thermal conductivity of gallium arsenide compared to silicon
results in self-heating effects in GaAs MESFETs that limit the electrical
performance of such devices for high power applications. To date, analytical
thermal models of self heating in GaAs MESFETs are based on the assumption
of a uniformly heated channel....
Missing data can lead to biased and inefficient estimation if the missing mechanism is not taken into account in the analysis. In this dissertation we propose two estimators that, under fairly general conditions, are asymptotically unbiased. The first proposed estimator assume the data are missing at random (MAR) and does...
The management options chosen by decision makers in
managing wildlife and fisheries have different effects for
diverse user groups. As a result, natural resource management
agencies often seek information to evaluate the effects of
alternative policies on the benefits provided to different
constituencies. Over the past decade, economists have
developed...
An important step in the design of digital networks lies in the derivation of the switching formulas which describe the combinational logic networks in the system. In most large systems the number of gates and the number of connections are major factors that affect the cost of the system. An...
