Phonetic Faithfulness in Phonological Opacity
… presents a novel approach to phonological opacity, which is grounded in new findings regarding substantive restrictions on the patterns of opaque interactions. The central thesis posits that phonological opacity functions to preserve the phonetic properties specified in the input of a …

Predictive model for plume opacity
… utility sources have experienced increased plume opacity. Cases of plume opacity exceeding in-stack opacity are due to 1) the aerosol formed by condensation of primary sulfuric acid and water vapor onto polydisperse plume particles and 2) the presence of fine particles which grow into the visual …

Reaching for Opacity: Contemporary Afrodiasporic Literature
… explored in this dissertation defends a shared opacity as the ground of ethical life, thereby reimagining our relation to distant geographies, lost ancestries, broken inheritances, and shattered subjectivities. Offering readings of writers such as Edwidge Danticat, Fred Moten, M. NourbeSe …

Oblique Strategies: Queer Opacity in Figurative Painting
… is underpinned by critical theory that proposes opacity as an alternative to absolute visibility. Cultural theorists Nicholas de Villiers and Clare Birchall are exemplary scholars engaging in the field of opaque politics, which informs my own theoretical framework. My studio methodology engages …

Characterisation of Streptococcus pneumoniae opacity phase variation
… the mechanism involved in the switch between opacity phenotypes is not known and there is discordance in the literature in terms of the precise molecular differences between them. This project set out to comprehensively characterise phenomic (2D-DIGE), transcriptomic (DNA microarray) and …

Relationality and Opacity: Approaching Trans in Cinema
… room for manoeuvre and offering measures of opacity. Reading for opacity, I propose, offers ways to read for forms of trans relationality that persist in excess of the abstractions that have put trans towards other purposes. In chapter one, I trace and interrogate themes of isolation, …

Optimal payoff to ensure opacity in Discrete-Event Systems
Opacity is a property of systems which guarantees that an outside observer cannot distinguish some behaviour of the system (secrets) from other behaviours (non-secrets). Many companies and government agencies like to make some aspects of their processes opaque to any observer while still needing to …

The Real Effects of Opacity: Evidence from Tax Avoidance
… on the direction of the association, namely that opacity causes tax avoidance. Similarly, the results from tests using the initial enforcement of insider trading laws provide additional support for a directional hypothesis. In support of the firm-level findings, I also find evidence in the …

Word order, NP movements, and opacity conditions in Persian
This study investigates word order and NP-movement phenomena in Persian within the framework of Government and Binding as developed in Chomsky (1981, 1986b) and subsequent work.

Tonal interaction in Kinande : cyclicity, opacity, and morphosyntactic structure
This dissertation develops a constraint-based analysis of opaque tonal interactions in Kinande verb forms and, based on this analysis, argues for a phonological architecture that incorporates both cyclic evaluation and constraint reranking. Evidence for cyclic evaluation comes from a close …

The HI Lyman-alpha opacity at redshift 2.7 < z < 3.6
Most of the baryonic matter in the Universe resides in a diffuse gaseous phase in-between galaxies consisting mostly of hydrogen and helium. This intergalactic medium (IGM) is distributed in large-scale filaments as part of the overall cosmic web. The luminous extragalactic objects that we can …

Differential Privacy and Opacity for Positive Linear Systems and Observers
… and observers via differential privacy and opacity. After reviewing relevant notation and background, wefirsttackletheproblem of building a differentially private mechanism that preserves positivity. We consider two methods of constructing these mechanisms: post-processing and restriction. We …

Identity Effects and Opacity in Syrian Arabic: An Optimality Theory Analysis
Chapter 5 shows how interdialectal differences stem from constraint ranking. Epenthesis and syncope in Iraqi and Egyptian Arabic are accounted for by permuting the constraint set that is present in the grammar of Syrian Arabic. A discussion of emphatic rounding in Lebanese Arabic is then pursued, …

Opacity Verification and Fault Diagnosis in the Framework of Switching Output Automata
… security and reliability problems. First, for opacity verification, we establish decidable procedures for both current-state opacity (where secrets are discrete states) and timed opacity (where secrets are global-state-duration triples specifying which combinations of discrete state, output, …
