Oramics: Atlantis Anew

A moving image work co-commissioned by the Science Museum (London), with extensive unprecedented access to the Oramics archive at Goldsmiths College and the Science Museum. Conceived of as an Artist's film in homage to Daphne Oram, the pioneer of British Electronic Music and co-founder of the BBC Radiophonic workshop in 1958, the film features a close-up encounter with her unique invention, the Oramics Machine, housed at the Science Museum in London. Oram used drawn sound principles to compose ‘handwrought' electronic music, and yet the visual nature of her work remains largely unseen and unsung. Exhibitions: ‘Oramics to Electronica’ Science Museum (London 2011-14); solo exhibition as part of the International Rotterdam Film Festival (2013); group exhibition ‘The Sight of Sound’, Deutsche Bank VIP Lounge, Frieze Art Fair, NY (2012); ‘Samsung Art+ Prize’ BFI Southbank, London (2012). Screenings: mini-retrospective at the Lincoln Centre, NY, as part of the New York Film Festival (2013); Jarman Award Tour screenings (2012, venues included Whitechapel Gallery, London; FACT, Liverpool; CCA, Glasgow; The Northern Charter in partnership with CIRCA projects; Nottingham Contemporary, Nottingham; Watershed, Bristol; Duke of York Cinema, Brighton); Mini-retrospective screening and in conversation with Lis Rhodes, Tate Britain (London 2014); Mini-retrospective screening, DIM Cinema, The Cinematheque (Vancouver 2015); Mini-retrospective at Whitechapel Gallery (London 2016).

IP/optical integration in access network infrastructures: key issues on resource provisioning

This thesis contributes to the advancement of Fiber-Wireless (FiWi) access technologies, through the development of algorithms for resource allocation and energy efficient routing. FiWi access networks use both optical and wireless/cellular technologies to provide high bandwidth and ubiquity, required by users and current high demanding services. FiWi access technologies are divided in two parts. In one of the parts, fiber is brought from the central office to near the users, while in the other part wireless routers or base stations take over and provide Internet access to users. Many technologies can be used at both the optical and wireless parts, which lead to different integration and optimization problems to be solved. In this thesis, the focus will be on FiWi access networks that use a passive optical network at the optical section and a wireless mesh network at the wireless section. In such networks, two important aspects that influence network performance are: allocation of resources and traffic routing throughout the mesh section. In this thesis, both problems are addressed. A fair bandwidth allocation algorithm is developed, which provides fairness in terms of bandwidth and in terms of experienced delays among all users. As for routing, an energy efficient routing algorithm is proposed that optimizes sleeping and productive periods throughout the wireless and optical sections. To develop the stated algorithms, game theory and networks formation theory were used. These are powerful mathematical tools that can be used to solve problems involving agents with conflicting interests. Since, usually, these tools are not common knowledge, a brief survey on game theory and network formation theory is provided to explain the concepts that are used throughout the thesis. As such, this thesis also serves as a showcase on the use of game theory and network formation theory to develop new algorithms.

Radio over fiber broadband access networks architectures based on wavelength division multiplexing techniques

The recent remarkable growth in bandwidth of both wired optical and wireless access networks supports a burst of new high bandwidth Internet applications such as: peer-topeer file sharing, cloud storage, on-line gaming, video streaming, etc. Within this scenario, the convergence of fixed and wireless access networks offers significant opportunities for network operators to satisfy user demands, and simultaneously reduce the cost of implementing and running separated wireless and wired networks. The integration of wired and wireless network can be accomplished within several scenarios and at several levels. In this thesis we will focus on converged radio over fiber architectures, particularly on two application scenarios: converged optical 60 GHz wireless networks and wireless overlay backhauling over bidirectional colorless wavelength division multiplexing passive optical networks (WDM-PONs). In the first application scenario, optical 60 GHz signal generation using external modulation of an optical carrier by means of lithium niobate (LiNbO3) Mach- Zehnder modulators (MZM) is considered. The performance of different optical modulation techniques, robust against fiber dispersion is assessed and dispersion mitigation strategies are identified. The study is extended to 60 GHz carriers digitally modulated with data and to systems employing subcarrier multiplexed (SCM) mm-wave channels. In the second application scenario, the performance of WDM-PONs employing reflective semiconductor optical amplifiers (RSOAs), transmitting an overlay orthogonal frequency-division multiplexing (OFDM) wireless signal is assessed analytically and experimentally, with the relevant system impairments being identified. It is demonstrated that the intermodulation due to the beating of the baseband signal and wireless signal at the receiver can seriously impair the wireless channel. Performance degradation of the wireless channel caused by the RSOA gain modulation owing to the downstream baseband data is also assessed, and system design guidelines are provided.

Exploring and Improving Access to Direct Payments by People with Dementia Living in Rural Communities

Direct payments are cash payments made to individuals eligible for social care services which allow them to manage and pay for their own social care rather than receiving it directly from their Local Authority. Research suggests that direct payments can enable people with dementia to stay in their own home for longer, and experience greater choice, flexibility and an improved social life. However, uptake of direct payments is currently low. People living in rural communities may particularly benefit from the additional flexibility offered by direct payments; however they may face difficulties accessing appropriate services. The aim of Phase 1 of the research is to explore the reasons why people with dementia who live in rural communities do or do not gain access to direct payments. This will be achieved through analysis of direct payment uptake data, focus groups with social workers, examination of online discussions about direct payments, and interviews with people with dementia, carers and social workers. Findings will inform Phase 2 of the research: the building and pilot testing of an intervention which can be utilised in rural communities to maximise access to direct payments by people with dementia.

Exploring and Improving Access to Direct Payments by People with Dementia Living in Rural Communities

Direct payments are cash payments made to individuals eligible for social care services which allow them to manage their own social care. Research suggests that direct payments can enable people with dementia to stay in their own home for longer and experience greater choice, flexibility and an improved social life. However uptake of direct payments is currently low. The first objective of this research was to explore the experiences of people with dementia living in rural communities, in relation to their access to direct payments. 26 semi-structured interviews were conducted with people with dementia in receipt of social care services in the community, and their carers and social workers. Focus groups were carried out with two community social work teams. Direct payments appeared to afford particular benefits to people with dementia and to those living in rural communities in terms of flexibility, continuity of care and access to local facilities. However it was found that many service users were daunted by the thought of managing their own social care budget. The second objective of the research was to design and pilot test an intervention aimed at increasing uptake of direct payments by people with dementia. This comprised a session delivered to a team of social workers, aimed at encouraging them to offer combined direct payments to service users as a potentially less daunting alternative to full direct payments. Combined direct payments enable service users to receive part of their social care budget as a direct payment while the remainder is retained and managed by the Local Authority. In order to evaluate the intervention direct payment uptake will be examined for the six-month period before and after the intervention session, and social workers in the intervention team will be interviewed about their experiences of offering combined direct payments to service users.

Direct payments are cash payments made to individuals eligible for social care services which allow them to manage their own social care. Research suggests that direct payments can enable people with dementia to stay in their own home for longer and experience greater choice, flexibility and an improved social life. However uptake of direct payments is currently low. There is a lack of research to date in this area which addresses the factors of dementia, ageing and rurality in unison. Therefore the objective of this research was to explore the experiences of people with dementia living in rural communities, in relation to their access to direct payments. 26 semi-structured interviews were conducted with people with dementia in receipt of social care services in the community, and their carers and social workers. Focus groups were carried out with two community social work teams, and existing online discussions regarding direct payments were examined. It was found that direct payments tended to be seen as a fall back option, for example as the only alternative to residential care, or as a potential solution to problems experienced by existing social care service users. Direct payments appeared to afford particular benefits to people with dementia and to those living in rural communities in terms of flexibility, continuity of care and access to local facilities. It is therefore important that this group are enabled to access direct payments; ensuring direct payments are viewed as a positive option by all stakeholders is key to this.

Marginal Activity Access Cost (MAAC): a new indicator for sustainable Land Use/Transport (LUT) planning

The paper presents the ‘Marginal Activity Access Cost’, an accessibility indicator providing estimation in monetary terms of the impacts on mobility and on the environment of locating a single new activity in a specific zone of the urban area. In the first part of this paper, the new indicator is presented and compared to other accessibility indicators proposed in literature. In the second part, the MAAC is validated through an application to the urban area of Rome. The paper concludes with brief remarks on using the proposed accessibility indicator as index of performance for sustainable spatial planning.
