The Statistical Theory of Stationary Turbulence
This thesis concerns the theory of turbulence as well as that of wavelet transforms. The main contribution to the theory of turbulence is an extension of the von Karman-Howarth equation to turbulence that may be either two- or three-dimensional, and for which external forcing maintains the state of …

A statistical theory of the epilepsies
… for the epilepsies is proposed, based on the theory of bond percolation on finite lattices. Within this model, the onset of seizures in the brain is identified with the appearance of spanning clusters of neurons engaged in the spurious and uncontrollable electrical activity characteristic of …

Statistical theory of selectivity and conductivity in narrow biological ion channels : studies of KcsA
… challenge. In this thesis, we derive the theory of multi-species ionic conduction through narrow biological channels, taking into account ion-ion, ion-water and ion-channel interactions. The theories we derive lead to new results that describe multi-species conduction in and far from …

Predicting Kinetics of Spin-Dependent Reactions in an External Magnetic Field with Nonadiabatic Statistical Theory
… range of magnetic fields using the nonadiabatic statistical theory (NAST). The new computational methodology is applied to the spin-forbidden isomerization of the Ni(dpp)Cl₂ complex, revealing a notable increase in the rate constants under strong field conditions. We also discuss different …

A Statistical Theory of Fragmentations of Nuclei by Light Projectiles and Macroscopic Theory to Incorporate Resonances in the Mean Field
… silicon by alpha-particle in terms of a modified statistical model. The production cross sections are calculated using an average potential, where a broad resonances are assumed. In case resonances are very narrow, and very closed space, one needs to incorporate the resonance effect in the …

A statistical perspective on machine learning: three essays on improvement, application and interpretation of predictive algorithms
… the improvement of predictive algorithms using statistical concepts, potential and challenges in the application of predictive algorithms in areas traditionally covered by statistical theory, and the interpretation of black-box algorithms by means of statistical hypothesis testing.

Spectral Energy Dynamics and Wavevector Resonance in a Weakly Nonlinear Chaotic Elastodynamic Billiard
… as fully diffuse and described by a universal statistical theory. A theoretical prediction of the average mode-coupling strength is obtained. Comparison is made between the theory and results of direct numerical simulations performed for an ensemble of two-dimensional rough-wall billiards. The …

Inference from Limited Observations in Statistical, Dynamical, and Functional Problems
… domain. In each setting, prior knowledge of statistical, dynamical systems, and physical theory allow us to constrain the inferences and predictions we make from observational data. This domain knowledge becomes of paramount importance when the data we observe is limited: due to missing …

GENERATION, MECHANICAL AND STATISTICAL ANALYSIS, AND FEM SIMULATION OF FRACTURE OF REPEATABLE RANDOM ROUGH SURFACES
… topology. This study couples experimental and statistical theory, and FEM to extend knowledge of life of materials from initial service surface conditions through surface damage accumulation. Statistical moments and other parameters were correlated with fracture locations probability (H/N), …

Bayes and minimum variance unbiased estimators of reliability using the truncated Weibull life testing model
In recent years, statistical theory has become widely used in the study of reliability. In this study, we shall consider two types of estimators, namely, the Bayes and minimum variance unbiased estimators for the scale parameter θ in the truncated Weibull life testing model when the shape parameter …

A comparison of the effects of non-normal distributions on tests of equivalence
<p>Statistical theory and its application provide the foundation to modern systematic inquiry in the behavioral, physical and social sciences disciplines (Fisher, 1958; Wilcox, 1996). It provides the tools for scholars and researchers to operationalize constructs, describe populations, and measure …
