The soundscape as time capsule: A creative project based on the sounds of the first train station of Cuenca

This article reflects on the changing environment through the passage of time and how certain technologies for a creative proposal allow the preservation and transmission of a significant part of that ephemeral heritage for future generations. The general purpose of this particular project is aimed to achieve the sound synthesis of a specific and representative cityscape as the old train station in Cuenca –located in the heart of the city– that could be preserved and reproduced as an unique document of a present time, ascertainable in the future: a memory that interpret sound as a time capsule. This soundscape was made to mark the arrival of the high speed train in 2010 to a brand new station in the outskirts of the city. Therefore, the goal of this research was focused on achieving a synthetic document that provided a sound memory capable of reflecting the significant social, cultural and logistical features, of what was until then the only railway communication symbol in the city of Cuenca from 1883 to the first decade of the 21st century.

Achieving Space and Time Diversity by Using Lattice Constellation Based Joint Alamouti Coding

In this letter, we propose a simple space-time code to simultaneously achieve both the space and time diversities over time dispersive channels by using two-dimensional lattice constellations and Alamouti codes. The proposed scheme still reserves full space diversity and double-real-symbols joint maximum likelihood decoding which has the similar computation complexity as the Alamouti code.

The Creative Life of Law: Improvisation, Between Tradition and Suspicion

Originally applying solely to chefs, waiters, dishwashers and the like, New York City (NYC) regulations governing cabaret employees were altered in 1943 to include musicians and entertainers, who until the late 1960’s would be required to hold a NYC Cabaret Employee’s Identification Card. The introduction of these notorious “police cards” occurred roughly contemporaneously to the emergence in after-hours night clubs in Harlem of a new and supposedly “wild”, improvisatory brand of jazz: bebop. This article adds to the many rather practical theories on why these cards were introduced a more abstract discussion coined in terms of the relationship between suspicion and tradition and focusing on differing essences of law and improvisatory jazz. While law breathes tradition and is suspicious of improvisation and unpredictability, the converse is true of jazz. Allusion to tradition in jazz improvisation is often viewed as a betrayal of its creative and spontaneous nature. And yet it is only through its departure from the stable transmission of past meaning that improvisation gains meaning. Law, in contrast, while appearing to be entirely composed of tradition, to transmit some sort of determinate and fixed meaning, is constantly betraying itself. As no two legal actions can be exactly the same, judges must improvise on tradition and past precedent every time they are asked to decide a case. Law can thus neither dispense with nor be completely determined by tradition. The legal decision instead lies on the border between what it “is” and what it otherwise could be and every judicial act is, in some sense, a species of improvisation. This article uses the cabaret cards to explore this uncertain terrain between law and improvisation, between tradition and suspicion.

Reconfigurable system-on-a-chip motion estimation architecture for multi-standard video coding

A new domain-specific, reconfigurable system-on-a-chip (SoC) architecture is proposed for video motion estimation. This has been designed to cover most of the common block-based video coding standards, including MPEG-2, MPEG-4, H.264, WMV-9 and AVS. The architecture exhibits simple control, high throughput and relatively low hardware cost when compared with existing circuits. It can also easily handle flexible search ranges without any increase in silicon area and can be configured prior to the start of the motion estimation process for a specific standard. The computational rates achieved make the circuit suitable for high-end video processing applications, such as HDTV. Silicon design studies indicate that circuits based on this approach incur only a relatively small penalty in terms of power dissipation and silicon area when compared with implementations for specific standards. Indeed, the cost/performance achieved exceeds that of existing but specific solutions and greatly exceeds that of general purpose field programmable gate array (FPGA) designs.

Beyond the shadow space: architecture as a professional and creative process; during and post-conflict.

Introduction

Much has been written about the impact of conflict on the physical nature of cities; most obviously perhaps the damage, destruction, defensive construction and spatial reconfigurations that evolve in times of conflict. Set within the context of Belfast, Northern Ireland, this paper will focus on three areas. First, a closer reading of the long-term physical impact of conflict, in particular, the spatial forms and practices that persist conceptually and culturally, and/or resist re-conceptualisation. Secondly, the effect of conflict on the nature of architectural practice itself, considering whether issues such as appointment and procurement impacted on architectural expectation and the context of operation. Thirdly, the effect of conflict on people, in particular in relation to creativity and hence the psyche of practice itself. This section will also identify the conditions that undermine or support design quality and creativity not only within times of conflict but also as society evolves out of the shadow space. 1
Twelve years on from the Peace Agreement,2 it may seem remarkable from an external perspective that Northern Ireland still needs to be reflecting on its troubled past. But the immediate post-conflict phase offered the communities of Northern Ireland place and time to experience ‘normal life’, begin to reconcile themselves to the hurt they experienced and start to reconfigure their relationships to one another. Indeed, it has often been expressed that probing the issues too much, at too early a phase, might in fact ‘Open old wounds without resolving anything’ and/or ‘Destabilise the already fragile political system.’3 This tendency not to deliberate or be too probing is therefore understandable and might be the reason why, for example, Northern Ireland's first Architecture and Built Environment policy, published in June, 2006, contains only one routine reference to ‘the Troubles’.

Clearly, however, there is a time in the development of a healthy, functioning society, when in order effectively to plan its future, it must also carry out a closer reading and deeper understanding of its past. As Maya Angelou puts it, ‘History, despite its wrenching pain/ Cannot be unlived, and if faced/ With courage, need not be lived again.’4

Increasingly, those within the creative arts sector and the built environment professions are showing interest in carrying out that closer reading, teasing out issues around conflict. This was led in part by the recent publication of the Troubles Archive by the Arts Council of Northern Ireland.5 Those involved in the academic or professional development of future generations of architects are also concerned about the relevance of a post-conflict condition. As a profession, if architects purport to be concerned with context, then the almost tangible socio-political circumstances and legacy of Northern Ireland does inevitably require direct eye contact. This paper therefore aims to bring the relationship between conflict and architectural practice in Northern Ireland into sharp focus, not to constrain or dull creative practice but to heighten its potential.
