A parametric study of twenty earthen levee cross sections from southeastern Louisiana using the LMVD Method of Planes and other limit equilibrium procedures

Alfortish, Michael Kevin 2009 August 1900 (has links)
The LMVD Method of Planes has been used for many years by the New Orleans District of the U.S. Army Corps of Engineers to analyze the stability of flood control structures in the New Orleans hurricane protections system. The Method of Planes assumes a three-part, noncircular slip surface and generally does not satisfy any form of static equilibrium. In computing a factor of safety, the Method of Planes considers a balance of horizontal “resisting” and “driving” forces in computing a factor of safety. To better understand how the results of slope stability analyses with the Method of Planes compare with results from more rigorous procedures capable of analyzing slip surfaces with different shapes, a parametric study was performed by analyzing twenty earthen levee cross sections believed to represent the various levee configurations in southeastern Louisiana. Analyses were performed with a force equilibrium procedure that assumed a horizontal inclination for the interslice forces and Spencer’s (1967) procedure, and the results were compared with the solutions from the Method of Planes. The force equilibrium procedure with horizontal side forces was selected because the procedure is believed to yield results that are similar to results from the Method of Planes, and Spencer’s procedure was utilized because it is the only procedure considered in this study to completely satisfy static equilibrium. The analyses performed with the force equilibrium and Spencer’s procedures included analyses for the critical slip surfaces from the Method of Planes as well as analyses for critical circular and noncircular slip surfaces. It was shown with the results of the analyses that the shape of the assumed slip surface has a great effect on the differences in the factors of safety from Spencer’s procedure and the Method of Planes. / text

Charlotte Perkins Gilman: Naturalist Playwright

Tolle, Andrew 05 1900 (has links)
This study explores Charlotte Perkins Gilman’s use of the dramatic form to challenge Herbert Spencer’s social Darwinism by offering feminist adaptations of Darwin’s theories of natural and sexual selection. As she does in her career-defining manifesto, Women & Economics (1898), Gilman in her lesser-known plays deploys her own brand of reform Darwinism to serve the feminist cause. Despite her absence in histories of modern drama, Gilman actively participated in the establishment and development of this literary, historical, and cultural movement. After situating Gilman in the context of nineteenth-century naturalist theater, this thesis examines two short dramatic dialogues she published in 1890, “The Quarrel,” and “Dame Nature Interviewed,” as well as two full-length plays, Interrupted (1909) and the Balsam Fir (1910). These plays demonstrate Gilman’s efforts to use the dramatic form in her early plays to “rehearse” for Women & Economics, and in her later drama, to “stage” the theories she presents in that book.

Spencer's Principles of Psychology and the decline of utilitarian premises in British psychology.

Bissell, Gavin A. 03 1900 (has links)
Yes / Despite the revival of interest in nineteenth century psychology and ethics in Britain during the 1980s, and the current debate around Utilitarian ethics in medicine (Buckle, 2005) and care (Offer, 2004), Utilitarian premises, understood as a psychological theory rather than as a moral philosophy, remain largely dormant in contemporary British Psychology. This is so despite their apparent survival in Behaviourism (Plaud & Vogeltanz, 1994). This article examines aspects of their decline within Victorian psychology, by focussing upon the relatively neglected psychological writings of Herbert Spencer. In doing so, it seeks to make a modest contribution to unravelling the complex changes in the nature of nineteenth-century psychology. In particular it is argued that, whilst some explanations of the decline of Utilitarian premises in the Victorian development of psychology focus upon the later part of the century and cultural or institutional factors, an examination of Spencer's works at the mid-century supports the view that changes were under way earlier. Whilst several explanations might be offered for this, changes in economic organisation and in the experience of individual agency are highlighted. The relation between Utilitarian psychology and Utilitarian ethics will then be considered. Finally, at this stage it should be possible to comment upon the significance of the marginalization of Utilitarian premises within the development of Victorian psychology for the contemporary debate about health resource allocation. / ESRC

On the complexity of matrix multiplication

Stothers, Andrew James January 2010 (has links)
The evaluation of the product of two matrices can be very computationally expensive. The multiplication of two n×n matrices, using the “default” algorithm can take O(n3) field operations in the underlying field k. It is therefore desirable to find algorithms to reduce the “cost” of multiplying two matrices together. If multiplication of two n × n matrices can be obtained in O(nα) operations, the least upper bound for α is called the exponent of matrix multiplication and is denoted by ω. A bound for ω < 3 was found in 1968 by Strassen in his algorithm. He found that multiplication of two 2 × 2 matrices could be obtained in 7 multiplications in the underlying field k, as opposed to the 8 required to do the same multiplication previously. Using recursion, we are able to show that ω ≤ log2 7 < 2.8074, which is better than the value of 3 we had previously. In chapter 1, we look at various techniques that have been found for reducing ω. These include Pan’s Trilinear Aggregation, Bini’s Border Rank and Sch¨onhage’s Asymptotic Sum inequality. In chapter 2, we look in detail at the current best estimate of ω found by Coppersmith and Winograd. We also propose a different method of evaluating the “value” of trilinear forms. Chapters 3 and 4 build on the work of Coppersmith and Winograd and examine how cubing and raising to the fourth power of Coppersmith and Winograd’s “complicated” algorithm affect the value of ω, if at all. Finally, in chapter 5, we look at the Group-Theoretic context proposed by Cohn and Umans, and see how we can derive some of Coppersmith and Winograd’s values using this method, as well as showing how working in this context can perhaps be more conducive to showing ω = 2.
