Convexity-Preserving Scattered Data Interpolation

Description: Surface fitting methods play an important role in many scientific fields as well as in computer aided geometric design. The problem treated here is that of constructing a smooth surface that interpolates data values associated with scattered nodes in the plane. The data is said to be convex if there exists a convex interpolant. The problem of convexity-preserving interpolation is to determine if the data is convex, and construct a convex interpolant if it exists.

Historical Reconstruction and Self-Search: A Study of Thomas Pynchon's V.. John Barth's The Sot-Weed Factor. Norman Mailer's The Armies of the Nicrht. Robert Coover's The Public Burning, and E.L. Doctorow's The Book of Daniel

Description: A search for self through historical reconstruction constitutes a crucial concern of the American postmodern historical novels of Pynchon, Barth, Mailer, Coover, and Doctorow. This concern consists of a self-conscious dramatization, paralleled by contemporary theorists' arguments, of the constructedness of history and individual subject. A historian-character's process of historical inquiry and narrative-making foregrounded in these novels represents the efforts by the postmodern self to (re)co… more

The Use of Jazz in Opera

Description: Methods of incorporating jazz in opera range from using simple blue notes and fox-trot rhythms, to utilizing jazz instruments, to employing elaborate passages of improvisation. Current definitions of "jazz opera" do not consider variations in the genre, which, because of their evolving nature and the varied background of their composers, are diverse. This study attempts to collectively discuss these third-stream works. Jazz rhythms and harmonies first appeared in the 1920s in the works of Gersh… more

The Effect of Auditor Knowledge on Information Processing during Analytical Review

Description: Auditors form judgments by integrating the evidence they gather with information stored in memory (knowledge). As they acquire experience, auditors have the opportunity to learn how different patterns of evidence are associated with particular audit problems. Research in experimental psychology has demonstrated that individuals with task-specific experience can match the cues they encounter with patterns they have learned, and form judgments without consciously analyzing the individual cues.

Applications of Reductive Analytical Techniques in the Phrygian Settings of the Orgelbüchlein by J.S. Bach

Description: This study aims to two problematic aspects of the Phrygian mode: a. the development of a harmonic pattern at the cadence that differs from that of the other modes and of the major and minor modes as well; b. the observation that the Phrygian scale inverts all of the intervallic properties of the Major scale. The result of these two observations is that when the reductive techniques of Heinrich Schenker are applied in the Phrygian repertory, melodic and harmonic properties are brought into confl… more

Effects of External Electric Fields on Light Transmittance in Isolated Crayfish Nerves

Description: Acute effects of a pulsed external electric field (PEEF) at 20 V/cm and a d.c. EEF at 90 V/cm on light transmittance in an isolated compound crayfish nerve was measured. In a third series, the nerve was pre-treated with the Na+ channel blocker tetrodotoxin (TTX). A PEEF produced an irreversible increase in the variation of light transmittance in normal nerves but a reversible increase in TTX treated nerves. This data was statistically insignificant. The d.c. EEFs produced a reversible and stati… more
