'Trustees of posterity': Benjamin Disraeli and the European Bildungsroman

This thesis studies Benjamin Disraeli's use of the form of the "Bildungsroman" to invent and discover himself. It shows how Disraeli's own life was developing as a "Bildungsroman" while writing four of his twelve novels, Contarini Fleming, Coningsby, Sybil and Lothair, during the period 1832-1870. As each of these four novels is studied in turn in Chapters I-IV respectively, Disraeli's recurring hero appears in four guises, thus illustrating how the form of the "Bildungsroman" undergoes subtle changes. In the open-ended Contarini Fleming (1832) with its emphasis on youth and ambition, Disraeli had intended to create a work similar to the classical German "Bildungsroman" portraying the development of a character. Despite its many comparisons with Goethe's paradigmatic Wilhelm Meisters Lehrjahre, Disraeli's early novel has more of an affinity with Stendhal's Le rouge et Ie noire. The eponymous hero of Coningsby has the distinguishing quality of "insipidness" and is seen from the perspective of an exemplary class representative of the aristocracy. This novel is taken as an example of the English "Bildungsroman", an English "fairy story" because Coningsby's destiny is already predetermined. The hero of Sybil, Charles Egremont's conviction is that one's identity is not inherited but created, which returns to the classical ideal of "Bildung", and which Disraeli reformulated as "vocation". It is argued that poverty and its relief was not the theme of Sybil but was used to point to the opportunities open to a reeducated aristocracy. In Chapter IV it is shown that it is only with Lothair, written in old age, that Disraeli discovers himself and achieves a successful classical "Bildungsroman". The narrator evaluates the represented events in a restrained and indirect manner and demonstrates a concern with analysing what is involved in the hero's discovery of himself and the world. The "Bildungsroman's" valorization of the existing social order prompts Lothair to look towards the past. He refuses to consider the future still open and his discontinuation of the quest for a philosophy of life is presented as a sign of his achieved maturity and his "Bildung" is concluded. In these four self-referential works Disraeli constructed a composite character whose biography was that of the author himself

The motion of a viscous filament in a porous medium or Hele-Shaw cell: a physical realisation of the Cauchy-Riemann Equations

We consider the motion of a thin filament of viscous fluid in a Hele-Shaw cell. The appropriate thin film analysis and use of Lagrangian variables leads to the Cauchy-Riemann system in a surprisingly direct way. We illustrate the inherent ill-posedness of these equations in various contexts

Adaptation of multidimensional group particle tracking and particle wall-boundary condition model to the FDNS code

A particulate two-phase flow CFD model was developed based on the FDNS code which is a pressure based predictor plus multi-corrector Navier-Stokes flow solver. Turbulence models with compressibility correction and the wall function models were employed as submodels. A finite-rate chemistry model was used for reacting flow simulation. For particulate two-phase flow simulations, a Eulerian-Lagrangian solution method using an efficient implicit particle trajectory integration scheme was developed in this study. Effects of particle-gas reaction and particle size change to agglomeration or fragmentation were not considered in this investigation. At the onset of the present study, a two-dimensional version of FDNS which had been modified to treat Lagrangian tracking of particles (FDNS-2DEL) had already been written and was operational. The FDNS-2DEL code was too slow for practical use, mainly because it had not been written in a form amenable to vectorization on the Cray, nor was the full three-dimensional form of FDNS utilized. The specific objective of this study was to reorder to calculations into long single arrays for automatic vectorization on the Cray and to implement the full three-dimensional version of FDNS to produce the FDNS-3DEL code. Since the FDNS-2DEL code was slow, a very limited number of test cases had been run with it. This study was also intended to increase the number of cases simulated to verify and improve, as necessary, the particle tracking methodology coded in FDNS

Computational analysis of the SSME fuel preburner flow

A computational fluid dynamics model which simulates the steady state operation of the SSME fuel preburner is developed. Specifically, the model will be used to quantify the flow factors which cause local hot spots in the fuel preburner in order to recommend experiments whereby the control of undesirable flow features can be demonstrated. The results of a two year effort to model the preburner are presented. In this effort, investigating the fuel preburner flowfield, the appropriate transport equations were numerically solved for both an axisymmetric and a three-dimensional configuration. Continuum's VAST (Variational Solution of the Transport equations) code, in conjunction with the CM-1000 Engineering Analysis Workstation and the NASA/Ames CYBER 205, was used to perform the required calculations. It is concluded that the preburner operational anomalies are not due to steady state phenomena and must, therefore, be related to transient operational procedures

A method of automatically stabilizing helicopter sling loads

The effect of geometric and aerodynamic characteristics on the stability of the lateral degrees of freedom of a typical helicopter sling load is examined. The feasibility of stabilizing the suspended load by controllable fins was also studied. Linear control theory was applied to the design of a simple control law that stabilized the load over a wide range of helicopter airspeeds

Crystallization of random trigonometric polynomials

We give a precise measure of the rate at which repeated differentiation of a random trigonometric polynomial causes the roots of the function to approach equal spacing. This can be viewed as a toy model of crystallization in one dimension. In particular we determine the asymptotics of the distribution of the roots around the crystalline configuration and find that the distribution is not Gaussian.Comment: 10 pages, 3 figure

New Concepts in Pacemaker Syndrome

After implantation of a permanent pacemaker, patients may experience severe symptoms of dyspnea, palpitations, malaise, and syncope resulting from pacemaker syndrome. Although pacemaker syndrome is most often ascribed to the loss of atrioventricular (A-V) synchrony, more recent data may also implicate left ventricular dysynchrony caused by right ventricular pacing. Previous studies have not shown reductions in mortality or stroke with rate-modulated dual-chamber (DDDR) pacing as compared to ventricular-based (VVI) pacing. The benefits in A-V sequential pacing with the DDDR mode are likely mitigated by the interventricular (V-V) dysynchrony imposed by the high percentage of ventricular pacing commonly seen in the DDDR mode. Programming DDDR pacemakers to encourage intrinsic A-V conduction and reduce right ventricular pacing will likely decrease heart failure and pacemaker syndrome. Studies are currently ongoing to address these questions

Uniform asymptotics of the coefficients of unitary moment polynomials

Keating and Snaith showed that the $2k^{th}$ absolute moment of the characteristic polynomial of a random unitary matrix evaluated on the unit circle is given by a polynomial of degree $k^2$. In this article, uniform asymptotics for the coefficients of that polynomial are derived, and a maximal coefficient is located. Some of the asymptotics are given in explicit form. Numerical data to support these calculations are presented. Some apparent connections between random matrix theory and the Riemann zeta function are discussed.Comment: 31 pages, 1 figure, 2 tables.
