English Phonology Without Underlying Glides

Description: This dissertation demonstrates that the optimal account of English phonology denies phonemic status to oral glides. That is, it shows that all instances of phonetic [y] and [w] are predictable by rule. These occurrences include the following: formative initial glides, such as those in yet and wet; post-consonant, pre-vocalic [w] in such forms as quit, guava, and white and post-consonant, pre-vocalic [y] in such forms as cute, few, million, onion, and champion; the [y] following the tense vowels… more

Enhanced Coarse-Graining for Multiscale Modeling of Elastomers

Description: One of the major goal of the researchers is to reduce energy loss including nanoscale to the structural level. For instance, around 65% of fuel energy is lost during the propulsion of the automobiles, where 11% of the loss happens at tires due to rolling friction. Out of that tire loss, 90 to 95% loss happens due to hysteresis of tire materials. This dissertation focuses on multiscale modeling techniques in order to facilitate the discovery new rubber materials. Enhanced coarse-grained models o… more

The Enlightenment Legacy of David Hume

Description: Although many historians assert the unity of the Enlightenment, their histories essentially belie this notion. Consequently, Enlightenment history is confused and meaningless, urging the reader to believe that diversity is similarity and faction is unity. Fundamental among the common denominators of these various interpretations, however, are the scientific method and empirical observation, as introduced by Newton. These, historians acclaim as the turning point when mankind escaped the ignoranc… more

Ensemble Singing in the Bel Canto Salon Repertory: A Pedagogical Reconsideration

Description: Vocal duets have had a long history in the Western classical music tradition. Their use as a teaching resource can be traced back to the Renaissance, where duets were used for the development of singing, performance, and musicianship. In the late 19th and all of the 20th centuries, this pathway of vocal pedagogy has markedly declined. This study proposes a reintroduction of this methodology of teaching, asserting that it provides the collegiate vocal student with maximum opportunity for growth … more

An entropic approach to the analysis of time series.

Description: Statistical analysis of time series. With compelling arguments we show that the Diffusion Entropy Analysis (DEA) is the only method of the literature of the Science of Complexity that correctly determines the scaling hidden within a time series reflecting a Complex Process. The time series is thought of as a source of fluctuations, and the DEA is based on the Shannon entropy of the diffusion process generated by these fluctuations. All traditional methods of scaling analysis, instead, are base… more
