The Relation of the One-Act Play to the Short Story

This is a 1913 thesis written by Lita Battey entitled, "The Relation of the One-Act Play to the Short Story"

Nodewebba: Software for Composing with Networked Iterated Maps

Nodewebba software provides a GUI implementation of the author’ s “Variable-Coupled Map Networks” (VCMN) approach to algorithmic composition. A VCMN node consists of a simple iterated map, timing controls, and controls for mapping the node output to musical parameters. These nodes can be networked, routing the outputs of nodes to control the variables of other nodes. This can enable complex emergent patterning and provides a powerful tool for creating musical materials that exhibit interrelated parts. Nodewebba also provides API hooks for programmers to expand its functionality. The author discusses the design and features of Nodewebba, some of the technical implementation issues, and a brief example of its application to a compositional project

Editing Strategies for Bézier-Modeled Continuous Expression Curves

PICACS (Pitch Curve Analysis and Composition System) is a software prototype inspired in part by study of Indian classical music. The primary motivation of the system is to facilitate analysis, composition, and convincing computer rendering of music that is characterized by detailed, expressive shaping of the continuum between scale steps. The system creates models of pitch, amplitude, and spectral-centroid expression envelopes by utilizing nonlinear least-squares fitting of constrained Bézier spline curves. Details of the modeling system have been published elsewhere; this paper focuses on the unique challenges that arise in designing an editing system for such models to support compositional purposes. While some of the challenges are specific to the Bézier model, it is clear that many of the challenges would apply to any system that seeks to support modelling and editing of continuous expression using sets of linked curves and multiple layers of expression data

Towards a Fluid Audiovisual Counterpoint

The author critiques and expands his concept of "fluid audiovisual counterpoint" by investigating the relevance of the species counterpoint tradition in music to conceptualizing audiovisual relationships in abstract video music. He points out both gains and limitations of such an approach, considering in particular issues of temporal and perceptual hierarchy, atomism, and gesture. He also considers how this might relate to Adam Basanta's 2013 proposed three-axes model of audiovisual relationship typologies. Ultimately, he proposes elements of a "phenomenological theory of audiovisual counterpoint", with fluidity being a subcategory. As an example, he considers how this subcategory might be informed by the relationship between the gestures of Indian classical vocalists and the music they are singing. Ultimately, the argument is made that complete systematization of audiovisual counterpoint is not possible, or even desirable, and that informing the artistic intuition by expanding possibilities and sensitivities would be the primary goal of an audiovisual counterpoint pedagogy

Distributed Estimation and Inference with Statistical Guarantees

This paper studies hypothesis testing and parameter estimation in the context of the divide and conquer algorithm. In a unified likelihood based framework, we propose new test statistics and point estimators obtained by aggregating various statistics from $k$ subsamples of size $n/k$, where $n$ is the sample size. In both low dimensional and high dimensional settings, we address the important question of how to choose $k$ as $n$ grows large, providing a theoretical upper bound on $k$ such that the information loss due to the divide and conquer algorithm is negligible. In other words, the resulting estimators have the same inferential efficiencies and estimation rates as a practically infeasible oracle with access to the full sample. Thorough numerical results are provided to back up the theory

The Quasigroup Block Cipher and its Analysis

This thesis discusses the Quasigroup Block Cipher (QGBC) and its analysis. We first present the basic form of the QGBC and then follow with improvements in memory consumption and security. As a means of analyzing the system, we utilize tools such as the NIST Statistical Test Suite, auto and crosscorrelation, then linear and algebraic cryptanalysis. Finally, as we review the results of these analyses, we propose improvements and suggest an algorithm suitable for low-cost FPGA implementation
