Single-phase active rectifier selection for fault tolerant machine

A fault tolerant, 5-phase PM generator has been developed for use on the low pressure (LP) shaft of an aircraft gas turbine engine. The machine operates at variable speed and therefore has a variable voltage, variable frequency electrical output (VVVF). The generator is to be used to provide a 350V DC bus for distribution throughout the aircraft, and a study has been carried out that identifies the most suitable AC-DC converter topology for this machine in terms of losses, electrical component ratings, filtering requirements and circuit complexity.

The Diary of Mary McKeon, an Irish American Domestic Servant in Nineteenth Century America

What did young, single, unaccompanied Irish women experience when immigrating to the United States in the late nineteenth century? In this final project, I will explore primary and secondary sources that address their experiences, focusing on a diary written in 1883 by a young Irish domestic servant working in New Haven, Connecticut. Mary McKeon, a sixteen-year-old girl from County Leitrim, Ireland, recorded her experiences as a domestic servant for two different families, as well as her own personal thoughts. Mary wrote down her personal experiences, providing a glimpse of what her life was like both inside and outside of her employer’s home. Though much of my research will show that many young women like Mary would be subjected to prejudice and discrimination due to their lack of understanding middle-class American values, which would give rise to the “Bridget” stereotype of a brutish, ill-mannered and incompetent domestic servant, not all Irish women experienced that discrimination and prejudice. Mary is one example of a domestic servant that was treated kindly by her employers and her story documents a more positive and supportive environment for this newly arrived young, single immigrant. Her diary also reveals her to be a young woman who worked to improve her language skills and her situation. And, through her diary, we get a glimpse of her strategies for ensuring an active social life, including access to courtship and marriage. By analyzing Mary’s diary and sharing my results in this final project, I hope to provide a more comprehensive view into the lives of these young women.

Active Energy: Three Mills - open workshop

On 14th May, as part of National Mills Weekend, an open workshop was held outside the 18th century House Mill in Bromley by Bow, the world's largest tidal mill. Members of the Geezers Club in Bow worked in the open air with an engineer to construct the stream wheel, which is being developed in ‘flat pack’ format to maximize transferability. The wheel will be installed in the River Lea later this year.

The Gentleman-Scholar at Home: Domesticity, Masculinity, and Civility in Dutch Seventeenth-Century Genre Painting

This dissertation examines the gentleman-scholar depicted at home in Dutch seventeenth-century genre paintings, focusing primarily on art created in the Northern Netherlands from the 1630s through the 1670s. The methodological approach is art historical but also pertains to history of architecture, history of dress, and gender studies. Employing the framework of the 'Ages of Man', this thesis investigates three related pictorial themes: the student, the scholar in his prime, and the aged scholar. Variations of male scholarly figures and the accoutrements of the study have a long history in Europe. Prototypical sources include religious history paintings of learned hermit-saints; artistic interest in the allegorical Saturnine persona; portraits of famous scholars; and the iconography of scholarly melancholy implied through vanitas allusions in portraiture and genre paintings. While the majority of Dutch genre paintings pertain to themes of women, male domestic routines form a small but important subset of this imagery and have not been studied. By the 1640s, this subject is readily identified by his setting, clothing, and actions. The ubiquity of scholarly attributes, such as books and globes, paired with the wearing of scholarly robes suggest the merits of intellectual curiosity and the privileges of studying as a pastime and designating a room as a study (studeerkamer). Distinct themes in genre also imply the challenges and rewards of scholarly activity pursued in concert with masculine civic and familial duty. Central to the development of this pictorial theme were: the innovative treatment of learned men by Rembrandt and his circle; the fijnschilder subjects of Dou; and the practice of amateur study by elite men, as suggested by the art of Vermeer. As this dissertation reveals, this convention did not grow to be consistent across the Northern Netherlands, nor was artistic interest limited to university towns. Rather, the larger relevance of scholars in Dutch society is evident in visual and literary sources. The domesticity of this figure in genre painting suggests that scholars mediated between an active and a contemplative life. Societal respect was garnered for scholars through their balance of familial and social duties with the honorable pastime of scholarly leisure.

Tempo atmosférico numa perspetiva CTS através do ensino por pesquisa

O ser Humano, desde sempre tem tentado estabelecer relações entre si, o tempo e o clima, de modo a melhorar as suas condições de vida. Atualmente existem questões problema que ameaçam a humanidade, nomeadamente as alterações climáticas e o aquecimento global com vista à promoção de um Desenvolvimento Sustentável. À educação é atribuída extrema importância no desenvolvimento de uma adequada perceção da situação do planeta. Este facto levou as Nações Unidas a proclamarem, no início deste século (dezembro de 2002), a Década da Educação para o Desenvolvimento Sustentável. Um desafio internacional lançado aos países para que recorram à educação como ferramenta essencial na promoção do Desenvolvimento Sustentável. A vida nas sociedades contemporâneas é extremamente influenciada pelos desenvolvimentos científicos e tecnológicos, dependendo dos seus respetivos progressos. Como tal, a Educação Científica assume um papel fundamental na compreensão das problemáticas que o ser Humano enfrenta, assim como na sua própria consciencialização da responsabilidade na situação planetária atual. Devendo promover o desenvolvimento de cidadanias proactivas, fundamentadas e responsáveis, no sentido da mudança, numa perspetiva crítica global que garanta a sustentabilidade do planeta. Estes factos são alvo de reflexão por parte de diversas instâncias da sociedade tais como a UNESCO, comunidades nacionais e internacionais de investigação em Educação Científica, e o poder político que se espelham em propostas de reforma e de revisão curricular em diversos países. Neste contexto, a Escola, como instituição formal de Educação, toma o papel primordial de promover o Desenvolvimento Sustentável através da aquisição de conhecimentos, atitudes, valores e competências que permitam desenvolver nos alunos uma consciencialização ecológica e uma literacia científica. Com este propósito em mente surge a questão investigativa deste estudo “Como Abordar o Tempo Atmosférico numa Perspetiva CTS Através do Ensino Por Pesquisa?”. Assim, usando o laboratório mais acessível e gratuito, a Atmosfera, e recursos facilmente acessíveis para desenvolver atividades simples é apresentada uma proposta de abordagem em sala de aula para a temática “Tempo Atmosférico” em particular a “Previsão e Descrição do Tempo Atmosférico”. A Atmosfera é um fascinante laboratório de ensino, porque nela se podem estudar alguns processos físicos lecionados ao longo dos mais variados níveis de ensino nas disciplinas de Física, Química e Geografia. Na Atmosfera, podem realizar-se diversos estudos simples, que de uma forma fácil respondem a inquietantes questões relacionadas com a Previsão e Descrição do Tempo Atmosférico. Neste estudo foi desenvolvida e usada uma metodologia para construir e interpretar mapas de tempo permitindo a alunos do 3º Ciclo do Ensino Básico fazer a Previsão e Descrição do Tempo Atmosférico. Após a aplicação da estratégia para o desenvolvimento de capacidades, de criatividade, envolvimento, cidadania e de pensamento crítico, os alunos responderam a um questionário. Através do tratamento dos dados obtidos pode-se considerar que em média 97% dos alunos consideram importante ou muito importante o estudo desta temática e que tem influência no seu dia-a-dia. Verificou-se que em média, se passou de 26% de respostas cientificamente corretas ou parcialmente corretas para 83% de respostas cientificamente corretas ou parcialmente corretas, o que demostra que a estratégia proposta atingiu os seus propósitos que passavam por dinamizar e fomentar uma cultura meteorológica nas escolas e para as escolas. Salienta-se a importância da possibilidade do trabalho em rede e das suas potencialidades na motivação dos alunos dada a oportunidade de fazer diagnóstico do tempo atmosférico local e inter-regiões. Os alunos consultaram e interpretaram mapas de tempo atmosférico, usaram a Internet e compreendam a relação e a influência entre diferentes parâmetros meteorológicos. Os resultados obtidos neste estudo permitem afirmar que os alunos desenvolveram competências numa área que é uma preocupação de cada um, o diagnóstico do tempo atmosférico. Cresceu neles uma cultura meteorológica e as aprendizagens nesta temática podem transbordar para colegas, amigos, pais e toda a comunidade escolar. Assim pode considerar-se que a estratégia implementada foi promotora de mudança, de aquisição de conhecimentos e do desenvolvimento de competências numa temática tão aliciante que envolve o Desenvolvimento Sustentável. Considera-se ainda que a estratégia usada neste estudo é motivadora, aliada à dinâmica CTS e ao Ensino Por Pesquisa, com vista a ser utilizada em contexto de sala de aula. Este estudo é uma forte contribuição para o Ensino das Ciências em especial no ensino da temática Tempo Atmosférico e é uma ferramenta importante que pode e deve ser utilizada em contexto escolar pois está escrito de modo a ser consultado por profissionais de ensino, nomeadamente pelos professores de Física, Química e de Geografia de modo a promoverem o desenvolvimento de competências de literacia científica e de cidadania e contribuir para a formação de futuros cidadãos ativos e conscientes defensores da Sustentabilidade da Terra.

Non-comital women of twelfth-century England: a charter based analysis

This thesis sets out to explore the place and agency of non-comital women in twelfth-century Anglo-Norman England. Until now, broad generalisations have been applied to all aristocratic women based on a long established scholarship on royal and comital women. Non-comital women have been overlooked, mainly because of an assumed lack of suitable sources from this time period. The first aim of this thesis is to demonstrate that there is a sufficient corpus of charters for a study of this social group of women. It is based on a database created from 5545 charters, of which 3046 were issued by non-comital women and men, taken from three case study counties, Oxfordshire, Suffolk and Yorkshire, and is also supported by other government records. This thesis demonstrates that non-comital women had significant social and economic agency in their own person. By means of a detailed analysis of charters and their clauses this thesis argues that scholarship on non-comital women must rethink the framework applied to the study of non-comital women to address the lifecycle as one of continuities and as active agents in a wider public society. Non-comital women’s agency and identity was not only based on land or in widowhood, which has been the one period in their life cycles where scholars have recognised some level of autonomy, and women had agency in all stages of their life cycle. Women’s agency and identity were drawn from and part of a wider framework that included their families, their kin, and broader local political, religious, and social networks. Natal families continued to be important sources of agency and identity to women long after they had married. Part A of the thesis applies modern charter diplomatic analysis methods to the corpus of charters to bring out and explore women’s presence therein. Part B contextualises these findings and explores women’s agency in their families, landholding, the gift-economy, and the wider religious and social networks of which they were a part.

Lady Nugent and Tom Cringle on the veranda : early nineteenth century observations on a Caribbean architectural feature

This study of the veranda as seen through the eyes of Lady Maria Nugent and Michael Scott, alias Tom Cringle, clearly demonstrates the important role that the piazza, as it was then more commonly known, played in the life of early nineteenth century Caribbean colonial society. The popularity of the veranda throughout the region, in places influenced by different European as well as African cultures, and among all classes of people, suggests that the appeal of this typical feature was based on something more than architectural fashion. A place of relative comfort in hot weather, the veranda is also a space at the interface of indoors and outdoors which allows for a wide variety of uses, for solitary or small or large group activities, many of which were noted by Nugent and Scott. Quintessentially, the veranda is a place in which to relax and take pleasure, not least of which is the enjoyment of the prospect, be it a panoramic view, a peaceful garden or a lively street scene. Despite the great changes in the nature of society, in the Caribbean and in many other parts of the world, the veranda and related structures such as the balcony continue to play at least as important a role in daily life as they did two centuries ago. The veranda of today’s Californian or Australian bungalow, and the balcony of the apartment block in the residential area of the modern city are among the contemporary equivalents of the lower and upper piazzas of Lady Nugent’s and Tom Cringle’s day.
