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.

In linear cascade wind tunnel tests, a high level of pitchwise periodicity is desirable to reproduce the azimuthal periodicity in the stage of an axial compressor or turbine. Transonic tests in a cascade wind tunnel with open jet boundaries have been shown to suffer from spurious waves, reflected at the jet boundary, that compromise the flow periodicity in pitch. This problem can be tackled by placing at this boundary a slotted tailboard with a specific wall void ratio s and pitch angle a. The optimal value of the s-a pair depends on the test section geometry and on the tunnel running conditions. An inviscid two-dimensional numerical method has been developed to predict transonic linear cascade flows, with and without a tailboard, and quantify the nonperiodicity in the discharge. This method includes a new computational boundary condition to model the effects of the tailboard slots on the cascade interior flow. This method has been applied to a six-blade turbine nozzle cascade, transonically tested at the University of Leicester. The numerical results identified a specific slotted tailboard geometry, able to minimize the spurious reflected waves and regain some pitchwise flow periodicity. The wind tunnel open jet test section was redesigned accordingly. Pressure measurements at the cascade outlet and synchronous spark schlieren visualization of the test section, with and without the optimized slotted tailboard, have confirmed the gain in pitchwise periodicity predicted by the numerical model.

This article introduces examples of recent sound art in Belfast, a city that has undergone radical transformation over the past decade and is home to a burgeoning community of sound artists. The text investigates the ways in which sonic art can redraw boundaries in a city historically marked by myriad political, socioeconomic,
religious and sectarian divisions. The article focuses on sound works that reimagine a “post-conflict” Belfast. These include site-specific sound installations in urban and public spaces, soundwalks, sculptures, locative and online works, and experimental
sonic performances that draw upon traditional Irish song and music.

This paper highlights the role of narratives in expressing, shaping and ordering urban life, and as tools for analysing urban conflicts. The paper distinguishes analytically between two prominent epistemological meta-narratives in contemporary urban studies and multiple ontological narratives in a given city-in this case Belfast. The first meta-narrative represents cities as sites of deepening coercion, violence and inequality and the second sees them as engines of new forms of transnational capitalism. Both are marked by the strategy of specifying 'exemplar' or 'paradigm' cities. The core of the paper addresses how these two meta-narratives map onto and interact with, three contemporary ontological narratives of urban regeneration in Belfast. We conceive of narratives-epistemological and ontological-as analytical tools and objects of analysis but also as tools for social action for competing political and economic interests and coalitions. While in the urban studies literature Belfast is typically studied as an exemplar 'conflict city', it is now being promoted as a 'new capitalist city'. In the context of post-Agreement Belfast, we explore not only the 'pull' of exemplar narratives but also resistances to them that are linked to multiple and hybrid senses of place in the city. We conclude that any significant move beyond the exigencies of rampant commodification or recurring inter-communal antagonism must firstly, encourage new forms of grassroots place-making and, secondly, reform of Belfast's (and Northern Ireland's) fragmented governance structures. © 2013 Copyright Taylor and Francis Group, LLC.

“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.

The art of drystone walling is a highly sustainable traditional practice which uses local materials and craftsmen. As no
mortar is used they have low embodied carbon, and much repair work or rebuilding can be carried out using very little if any new
materials. However local practices developed to suit local materials, leading to a range of construction styles, making them difficult to
assess. This paper examines a range of construction styles of drystone retaining walls in use across the United Kingdom.
Understanding of the substantial variations of construction style is essential to enable proper assessment of these structures. Different
frictional and weathering characteristics, and the naturally occurring shapes of stone found in an area, all affect the ways in which the
stones have traditionally been assembled into walls. Ease of construction also plays a part, as the craftsman will naturally wish to
achieve a robust construction in a way that is economical of time and effort. Aesthetics may be very important, for both client and
craftsman. It is also shown that construction style is influenced by the location and function of the structures, with harbour walls
particularly likely to have unique characteristics, and the reasons for this are explored.
