Application performance models provide insight to designers of high performance computing (HPC) systems on the role of subsystems such as the processor or the network in determining application performance and allow HPC centers to more accurately target procurements to resource requirements. Performance models can also be used to identify application performance bottlen....

Many cut flower crops are susceptible to both of impatiens necrotic spot virus (INSV) and tomato spotted wilt virus (TSWV) which are commonly vectored by Frankliniella fusca (Hinds) and F. occidentalis (Pergande) (Thysanoptera: Thripidae) in North Carolina. INSV and TSWV are among the most damaging plant diseases affecting the floriculture industry. Thrips were surveyed....

This thesis develops an algorithm for shape representation and matching. The algorithm is an object centered, boundary based method for shape recognition. Global features of the shape are utilized to define a frame of reference relative to which local shape features are characterized. The curvature of the boundary at a point is the local feature used. Curvature is compu....

To improve the analysis and control synthesis approach of linear fractional transformation (LFT) parameter-dependent systems, two types of non-quadratic Lyapunov function and switching control scheme are introduced and studied in this thesis. A gain-scheduled controller with parameter variation rate, a nonlinear gain-scheduled controller and an online switching linear p....

Nicotine and its derivatives are currently being synthesized and tested to explore their pharmaceutical capabilities in the treatment of Alzheimers disease, Parkinsons disease, and other central nervous system disorders. One area of research the Comins group has been undertaking is the development of methodologies for the synthesis of nicotine derivatives from natural n....

The purpose of this research is to better characterize the origin and evolution of mammalian development. This topic is addressed by examining maternal effects, temporal genetic effects, and hepatocyte endopolyploidy and their impact on mouse growth. This dissertation starts with a discussion of several well-characterized maternal effects and each effects influence on ....

Multidimensional (m-D) convolutional codes generalize the well known notion of a 1-D convolutional code defined over a univariate polynomial ring with coefficients in a finite field to multivariate polynomial rings. The more complicated structure of a multivariate polynomial ring when compared to a univariate one, however, makes the generalization nontrivial. While 1....

Fine particulate (PM2.5) continues to be a major air pollution problem due to its adverse effects on human health and the environment. Recently, the rapid industrialization now taking place in Asia is producing a large and growing quantity of NOX, SO2, CO and other atmospheric emissions. This research is part of the work of project Intercontinental Transport and Climati....

Wireless sensor networks have received a lot of attention recently due to its wide applications. Accurate and synchronized time is crucial in many sensor network applications due to the need for consistent distributed sensing and coordination. A number of time synchronization schemes have been proposed recently to address the resource constraints in sensor networks. How....

Effective data prefetching requires accurate mechanisms to predict embedded patterns in the miss reference behavior. This dissertation introduces a novel technique Spectral Prediction that accurately identifies the pattern by dynamically adjusting to its frequency. The proposed technique exploits the fact that addresses in the reference stream follow definite frequencie....

The conflict between essentialist and constructionist standpoints constitute the primary division between proponents of lesbian literary theory and queer theorists. While essentialists view identity as fixed and innate, constructionists consider identity to be the unstable effect of social conditioning. Lesbian theorists argue that the destabilization of all identity ca....
