Finite element analysis of free vibration of the delaminated composite plate with variable kinematic multilayered plate elements

Composite laminates are prone to delamination. Implementation of delamination in the Carrera Unified Formulation frame work using nine noded quadrilateral MITC9 element is discussed in this article. MITC9 element is devoid of shear locking and membrane locking. Delaminated as well as healthy structure is analyzed for free mode vibration. The results from the present work are compared with the available experimental or/and research article or/and the three dimensional finite element simulations. The effect of different kinds and different percentages of area of delamination on the first three natural frequencies of the structure is discussed. The presence of open-mode delamination mode shape for large delaminations within the first three natural frequencies is discussed. Also, the switching of places between the second bending mode, with that of the first torsional mode frequency is discussed. Results obtained from different ordered theories are compared in the presence of delamination. Advantage of layerwise theories as compared to equivalent single layer theories for very large delaminations is stated. The effect of different kinds of delamination and their effect on the second bending and first torsional mode shape is discussed. (C) 2014 Elsevier Ltd. All rights reserved.

Fabrication and Experimentation of a Cantilever Beam Based Piezoelectric Actuator and Sensor for Vibration Energy Harvesting

In the immediate surroundings of our daily life, we can find a lot of places where the energy in the form of vibration is being wasted. Therefore, we have enormous opportunities to utilize the same. Piezoelectric character of matter enables us to convert this mechanical vibration energy into electrical energy which can be stored and used to power other device, instead of being wasted. This work is done to realize both actuator and sensor in a cantilever beam based on piezoelectricity. The sensor part is called vibration energy harvester. The numerical analyses were performed for the cantilever beam using the commercial package ANSYS and MATLAB. The cantilever beam is realized by taking a plate and fixing its one end between two massive plates. Two PZT patches were glued to the beam on its two faces. Experiments were performed using data acquisition system (DAQ) and LABVIEW software for actuating and sensing the vibration of the cantilever beam.

Etos na poesia combatente de menestréis do rap: por uma análise das imagens discursivas no grito marginal do hip hop brasileiro

Este estudo tem como objetivo averiguar os efeitos de sentido produzidos por músicas de hip hop (movimento cultural cultivado nos guetos fluminenses), com base na análise de sua expressão verbal (rap) e em uma consideração experimental de capas de disco. Objetiva-se também investigar, no material artístico de Marcelo D2 e MV Bill, relações sociais engendradas por sujeitos da periferia, em espaços sociais antagônicos (centro e periferia). Para isso, exploramos uma Análise do Discurso de base enunciativa, enfatizando o conceito de etos discursivo, além de noções vinculadas à problemática da alteridade discursiva, a fim de que se analise o posicionamento de entes subjugados perante o descaso a que estão submetidos, e suas impressões sobre as imagens discursivas de marginalizadores. Buscamos apreender etos produzidos por sujeitos do rap, considerando a presença do Outro que fala nele/por ele (alteridade). Nossos procedimentos metodológicos apontam o que levou a considerar o hip hop, além da trajetória seguida na delimitação do corpus. Além disso, expõem-se os motivos que nos fizeram priorizar etos e alteridade discursiva. As análises buscam avaliações sobre a materialidade discursiva, que almejam extrair sentidos produzidos nos guetos. Como resultados, refletimos sobre aspectos inerentes ao contexto social fluminense, ao relacionamento entre sujeitos, lugares e práticas, para que se alarguem considerações sobre essas afinidades, inclusive na escola. Desse modo, ambicionamos que se aprimorem os debates sobre práticas de afirmação social de classes e, através de novas discussões, se intensifiquem as iniciativas sociopolíticas

Cartographic veracity in medieval mapping: analyzing geographical variation in the Gough Map of Great Britain

This article explores statistical approaches for assessing the relative accuracy of medieval mapping. It focuses on one particular map, the Gough Map of Great Britain. This is an early and remarkable example of a medieval “national” map covering Plantagenet Britain. Conventionally dated to c. 1360, the map shows the position of places in and coastal outline of Great Britain to a considerable degree of spatial accuracy. In this article, aspects of the map's content are subjected to a systematic analysis to identify geographical variations in the map's veracity, or truthfulness. It thus contributes to debates among historical geographers and cartographic historians on the nature of medieval maps and mapping and, in particular, questions of their distortion of geographic space. Based on a newly developed digital version of the Gough Map, several regression-based approaches are used here to explore the degree and nature of spatial distortion in the Gough Map. This demonstrates that not only are there marked variations in the positional accuracy of places shown on the map between regions (i.e., England, Scotland, and Wales), but there are also fine-scale geographical variations in the spatial accuracy of the map within these regions. The article concludes by suggesting that the map was constructed using a range of sources, and that the Gough Map is a composite of multiscale representations of places in Great Britain. The article details a set of approaches that could be transferred to other contexts and add value to historic maps by enhancing understanding of their contents.

Cinematic Peripheries of Dublin

The term periphery is, most of the time, used with or in relation to the centre. The ‘zoning’ taken by granted by the architect is unlike the one portrayed by the director who frames the differences of places in a non-linear manner. Film offers a constructed urban experience, suggesting the city to be a local network composed of nodes and links, rather than a centre and the margin. It is possible to talk about the construction of a new kind of network in film through a temporal representation of space, of the distant as the close. In this way, film may be a tool to shift the gaze from the bird’s-eye view to the eye level to create ‘a unified perceptual image of the city’, in Christine Boyer’s words. The experienced surface of the city is two-dimensional neither in fiction nor in reality. In this chapter, the nodes of Dublin are examined through two Irish films, Goldfish Memory (Elizabeth Gill, 2003) and Adam and Paul (Leonard Abrahamson, 2004). Specific elements of the city of Dublin, including walls, houses, pubs, streets, bridges, and parks, are analysed to understand the nature of the network of the city composed of nodes and their connections.

Sounds of the City

“Sounds of the City” is a large-scale community project and exhibition commissioned by the Metropolitan Arts Centre (MAC) and led by artists from the Sonic Arts Research Centre (SARC), Queen’s University Belfast. Over a four-month period, the artists worked together with two intergenerational groups in Belfast with the aim of addressing specific sound qualities of places, events and stories. Themes that surfaced from this process constitute the basis for the exhibition which promotes listening as a form of intersecting daily life, identity and memory. Five installations address aural contexts ranging from Belfast’s industrial heritage to the local family home. These are shaped by present and past experiences of workshop participants at Dee Street Community Centre in East Belfast and Tar Isteach in North Belfast. The themes and contents of these installations center upon the relationship between sound and memory, sound and place, and the documentation of everyday personal auditory experience.
All materials exhibited have emerged through workshops, interviews and field-recording sessions. Workshops acted as a basis from which to inform each group about the project’s aims, methods of listening, methods of documenting sound and the wider areas of soundscape studies and acoustic ecology. They also provided a central point allowing participants to organize outside activities and share material for exhibition.
“Sounds of the City” explores the relationship between sound and community through everyday life and presents a dynamic and ever-changing soundscape that shapes Belfast’s identity.

Sounds of the City has been exhibited at the MAC, Belfast 2012 and at Espaço Ecco, Brasilia 2013.

Michael Allen: Close Readings: Essays on Irish Poetry

The late Michael Allen was a member of the famous Belfast Group, and one of the most authoritative critical voices on poetry from Northern Ireland, intimately part of the North’s poetic movement since the early 1960s. He taught at Queen’s University, where he was a colleague of Seamus Heaney and tutor to poets such as Paul Muldoon and Medbh McGuckian. Seamus Heaney called him ‘the reader over my shoulder’. Close Readings brings together interlinked critical writings which have crucially influenced approaches to Irish poetry during the last forty years. The book ends with an extended essay, hitherto unpublished: ‘Doubles, Twins and the Feminine: Development in the Poetry of Michael Longley’.

Close Readings contains a Foreword by Fran Brearton, which relates Michael Allen’s essays to continuing critical and cultural debates. Edna Longley’s Afterword offers a personal view of Allen’s involvement with poetry in Belfast.

The complexities of tourism and regeneration: the case of the 2012 Olympic Games

Regeneration proposals typically seek to use a range of physical, economic and social initiatives to tackle inequality and improve areas. Often they attempt to change the image of places, making them more attractive to tourists, investors, and residents. The role of tourism in these regeneration processes is complex and contested. Tourism elements are often not well understood by decision-makers and sometimes create tensions with wider social regeneration aspirations. Using concepts from complexity theory, this paper interrogates the relationship between tourism and wider regeneration aspirations connected with the 2012 Olympic Games. It uses complexity theory to explore the context within which policies are developed, and the relationships between different policy initiatives. Both are highly complex, constantly evolving and sometimes ambiguous. It argues complexity concepts might be used to help to develop deeper understanding of the relationships between tourism and regeneration.

Destination images of non-visitors

This article provides much needed understanding of destination images held by non-visitors. Recognizing the characteristics of non-visitor images and their formation is important in order to understand images more widely. This qualitative study assesses images of London. The views of three hundred people in the Czech Republic who have never visited London were obtained via an innovative open-ended research instrument. The study showed that non-visitors imagine destinations through comparisons with their own experiences of places. Findings indicate that images can be very persistent and that the first images formed of a destination endure over time. Although the research is based on people with no direct experience of London, the research highlights that a range of secondary ‘experiences’ influence image formation.

Language support for immigrant children: a study of state schools in the UK and US

In recent decades, immigrants, refugees and asylum seekers have sought a new way of life in large numbers, often leaving their countries of origin behind in search of places that offer a better way of life. The purpose of this study was to investigate how elementary and middle school students in state schools in Reading, England (primarily speakers of Asian languages), and Richmond, Virginia (primarily speakers of Spanish), were supported academically, when most children's first language was not English. The authors were interested in exploring whether or not there were cultural or structural differences in the way each country helped or hindered these students as they progressed through the school systems. Three UK schools in a district of approximately 100,000 and three US schools in a district of approximately 250,000 were the focus of this exploration from 2000 to 2003. Findings indicated that there were cultural and legislative differences and similarities. Teachers and administrators in both countries attempted to provide services with limited and sometimes diminishing resources. Community support varied based on resources, attitudes toward various ethnic groups, and the coping strategies adopted by these groups in their new environments. Marked differences appeared with regard to the manner in which assessments took place and how the results were made available to the public.
