Automatic control -- Sensitivity. Structural control (Engineering). Strains and stresses -- Computer simulation. Structural analysis (Engineering). Engineering models.
Autonomous damage detection in engineering structures is critically important as the demands placed upon those structures are increased. It has been well established that damage detection can be done through monitoring the modal frequencies of the...
Polynomials. Finite fields (Algebra). Algebraic functions. Number theory.
The ring of univariate polynomials over a finite field shares many foundational arithmetic properties with the ring of rational integers. This similarity makes it possible for many problems in elementary number theory to be translated 'through the...
Sorting very large datasets is a key subroutine in almost any application that is built on top of a large database. Two ways to sort out-of-core data dominate the literature: merging-based algorithms and partitioning-based algorithms. Within these...
In this thesis we develop a theory of Fourier analysis and fast Fourier transforms (FFTs) for finite inverse semigroups. Our results generalize results in the theory of Fourier analysis for finite groups. There is a general method for generating...
Systemic sclerosis (SSc) is a rare and often-fatal systemic autoimmune disease characterized by vasculature dysfunction, immune activation, and extracellular matrix deposition in skin and internal organs. The etiology of SSc is unknown, but it is...
Mobile agents (Computer software). ; Electronic data processing -- Distributed processing. ; Sequential processing (Computer science) -- Mathematical models.
Mobile agents have received much attention recently as a way to efficiently access distributed resources in a low bandwidth network. Planning allows mobile agents to make the best use of the available resources. This thesis studies several planning...
Proteins -- Structure -- Data processing. Proteins -- Analysis -- Data processing. Nuclear magnetic resonance spectroscopy. Oligomers -- Analysis -- Data processing.
Symmetric homo-oligomers (protein complexes with similar subunits arranged symmetrically) play pivotal roles in complex biological processes such as ion transport and cellular regulation. Structure determination of these complexes is necessary in...
In this thesis, we consider several problems relating to cyclic subgroups of the group [mathematical equation]. Each element of [mathematical equation] has a unique representative in one of the two intervals [mathematical equation] and...
During our fieldwork with real-world organizations---including those in Public Key Infrastructure (PKI), network configuration management, and the electrical power grid---we repeatedly noticed that security policies and related security artifacts...
Information retrieval -- Mathematical models. ; Electronic information resource searching. ; Computer algorithms. ; Decision making -- Data processing. ; Mathematical optimization.
This thesis presents a unified method for simultaneous solution of three problems in Information Retrieval--metasearch (the fusion of ranked lists returned by retrieval systems to elicit improved performance), efficient system evaluation (the...
Medical imaging methods have become increasingly important in diagnosing diseases and assisting therapeutic treatment. In particular, early detection of breast cancer is considered as a critical factor in reducing the mortality rate of women....
Rats -- Behavior. Sexual behavior in animals. Vagina -- Psychophysiology. Cervix uteri -- Psychophysiology.
The present dissertation examined the contributions of vaginal and cervical stimulation to sexual motivation and reward in female rats. New, more complex behavioral methods such as the display of paced mating behavior and the induction of a...
Nitric oxide -- Analysis. ; Dithiocarbamates. ; Iron compounds. ; Organonitrogen compounds. ; Electron paramagnetic resonance spectroscopy.
Nitric oxide is synthesized by living organisms and plays important roles in circulatory, neurological, and immune function. Nitric oxide can also play pathophysiological roles, depending on the amount of the molecule, the presence of other species...
The use of non-selective vasodilators for the purpose of pulmonary vasodilation has, to date, given mixed results; systemic hypotension has been the limiting factor. Lipid soluble gases (e.g. volatile anesthetics) are capable of inducing smooth...
The heterochronic gene lin-14 affects certain somatic cell-fate choices during post-embryonic development in C. elegans. In lin-14 mutants, cells express stage-specific developmental programs, such as cell divisions or dauer entry, at inappropriate...
Most current multiprocessor file systems are designed to use multiple disks in parallel, using the high aggregate bandwidth to meet the growing I/O requirements of parallel scientific applications. Most multiprocessor file systems provide...
Hedgehog (HH) proteins play an important and evolutionary conserved patterning role in metazoan development. Aside from this physiological role, pathologically HH proteins are implicated in human developmental disorders and post-developmental...
The problem of perceived annoyance as a function of number of noise events and maximum noise level was investigated in a series of seven laboratory experiments. Four models were tested: the Equal Energy Model, the Scandinavian Model, the Variance...
Shape modeling is an important area in computer vision and medical imaging. Shape models have proved valuable in the tasks of object representation, recognition, and classification. This thesis focuses on shape models of 3D surfaces extracted from...
Non-ribosomal peptide synthetases (NRPS) are a family of enzymes that assemble a variety of pharmacologically interesting polypeptides from canonical and non-canonical amino acids. The identity and connectivity of the monomers in the final product...
