Investigation of high-efficiency Wireless Power Transfer criteria of resonantly-coupled loops and dipoles through analysis of the figure of merit

The efficiency of a Wireless Power Transfer (WPT) system is greatly dependent on both the geometry and operating frequency of the transmitting and receiving structures. By using Coupled Mode Theory (CMT), the figure of merit is calculated for resonantly-coupled loop and dipole systems. An in-depth analysis of the figure of merit is performed with respect to the key geometric parameters of the loops and dipoles, along with the resonant frequency, in order to identify the key relationships leading to high-efficiency WPT. For systems consisting of two identical single-turn loops, it is shown that the choice of both the loop radius and resonant frequency are essential in achieving high-efficiency WPT. For the dipole geometries studied, it is shown that the choice of length is largely irrelevant and that as a result of their capacitive nature, low-MHz frequency dipoles are able to produce significantly higher figures of merit than those of the loops considered. The results of the figure of merit analysis are used to propose and subsequently compare two mid-range loop and dipole WPT systems of equal size and operating frequency, where it is shown that the dipole system is able to achieve higher efficiencies than the loop system of the distance range examined.

The Human Figure in Drawing and Sculpture

My project as a Senior Scholar has been the study of the human figure through drawing and sculpture. I have worked directly from the model in order to understand the form and structure of the human body. The result of this concentrated study has been a sharpened sense of vision and an increased confidence in the use of materials for both two and three-dimensional representation.

Beyond Abrahamism : a fresh reading of the Tanakh traditions respecting Lot, Moab and Ammon

At the heart of this study is my interest in the way in which a religious community establishes its sense of identity and its boundaries in relation to other groups. I explore the case of Israel's attitude towards her eastern neighbours, the Moabites and Ammonites, as portrayed in Tanakh, the Hebrew Bible. Most commentary from the last one hundred years privileges one particular view of Moab and Ammon as traditional enemies of Israel. I aim to show the validity of readings of the biblical accounts that reveal a more complex relationship between Israel and her neighbours. Tanakh exhibits a dialectic between eirenic and hostile viewpoints. The stories of Abraham and Lot, who are presented as ancestors of Israel and of Moab and Ammon, to some degree represent Israel’s understanding of her neighbours. Conventional commentaries take for granted the accepted orthodoxy of Judaism, Christianity and Islam concerning Abraham and his significance in terms of faith and righteousness and blessing and covenant. As none of these notions is specifically linked to Lot at any point, he is treated as a pathetic figure and remains secondary in conventional commentary. Many commentaries denigrate the character of Lot, often in direct comparisons with Abraham. My reading of the texts of Genesis attempts to free the story of Lot from the constraints imposed by the way the story of Abraham functions. A careful reading of the Genesis account shows that Lot and Abraham exhibit similar elements of moral ambiguity, and Genesis contains no statement that condemns Lot on moral or religious grounds. Genesis 19, the single narrative in which Lot appears independently of Abraham, participates in the dialectic elsewhere in Tanakh. On the basis of a consistent pattern of action and speech throughout the first portion of Genesis 19, I advance my own original conception of the eirenic viewpoint of the narrator concerning Lot and his relationship to the divine. I attempt to demonstrate ways in which the story of Lot critiques or deconstructs the dominant ideology centred upon Abraham. My conception of the particular interests of the compiler of Genesis 19 is supported by several intertextual studies. These include the traditions of Sodom and of Zoar, the story of hospitality in Judges 19, the story of the deluge (Genesis 6-9) and stories of women who, like Lot’s daughters, act to continue the family line. In a treatment of the history of Lot traditions, I find evidence to separate the story of Lot from the work of the Yahwist. I consider whether the stories of Lot have a derivation east of the Jordan and whether the stories were of particular interest to the Deuteronomists. In the final chapter of this study, I focus on the main themes of the narratives concerning Lot and Abraham, and Moab and Ammon and Israel. The question of social boundaries arises in regard to many of these themes, such as the interaction of female and male, the role of wealth, the relation of city and country, kinship, and rights to land settlement. In this way, the treatment of Lot and Abraham in Tanakh and in subsequent traditions offers a perspective upon the formation of identity in the contemporary world of religious plurality.

"Rogue" figure skews attainment data

The ABS higher education attainment data has been skewed by a statistical blip that artificially inflated the 2009 figure, according to higher education researcher Alan Olsen.

Le vin : figure du paysage baudelairien

Este trabalho tem por objetivo fazer uma leitura filosófica da imagem do vinho na obra do escritor e crítico francês Charles Baudelaire. Analisa-se essa imagem como uma figura que estrutura o texto e que é também por ele estruturada. A figura do vinho é considerada como um elemento de base da estética desenvolvida pelo escritor francês. Portanto, este trabalho desenvolve uma análise mais textual à luz de noções filosóficas, considerando o vinho como uma “interimagem”, grão do texto baudelairiano. Essa imagem poética é o fio condutor para o estabelecimento de uma coerência, uma interpretabilidade outra da poética do autor de As flores do mal. Para tanto, esta dissertação analisa os elementos textuais concernentes à formação da imagem do vinho, suas reminiscências e o papel do poeta, relacionando sempre a crítica e a poesia.
