Distributed collaboration between industry and university partners in HE
Over the past three years the School of Design has been experimenting with an innovative curriculum design and delivery model named âthe Global Studioâ. The Global Studio is a cross-institutional research informed teaching and learning collaboration conducted between Northumbria University and international universities and industry partners based in the UK, USA, Netherlands and Korea. The aims of the Global Studio are directly linked with current and future industry needs that are related to changes in the organisation of product and service development. These changes highlight the importance of equipping design students with skills for working in globally networked organisations particularly the development of skills in intercultural communication and collaboration. In this paper we will focus on the Global Studio conducted in 2008 which included Northumbria University (UK), Hongik University (Korea), Auburn University (USA), Intel (USA), Motorola design studios located in the UK and Korea and Great Southern Wood (USA). These projects will be used to illustrate challenges and benefits of international collaborative industry-based projects undertaken in distributed settings
Institutionalising future geographies of financial inclusion: national legitimacy versus local autonomy in the British credit union movement.
This paper provides a critical overview of recent developments in British credit union development, and contributed to the broader analysis of alternative financial/economic spaces and (the geographies of) alterity. The paper was underpinned by a wide range of local, national and international conference presentations including the National Association of Credit Union Workers, Birmingham, 2001; Combating Financial Exclusion, Salford, 2001; Association of American Geographers, New York, 2001, New Orleans, 2003; Alternative Economic Spaces, Hull, 2005; and discussions with local user communities throughout the UK (including through non-academic publishing, such as SCCD news and New Start articles)
Magneto-seismology: effect of inhomogeneous magnetic field on transversal coronal loop oscillations
The extreme-ultraviolet (EUV) imagers onboard the planned Solar Dynamics Observatory (SDO) and Solar Orbiter (SO) will offer us the best chance yet of using observations of post-flare loop oscillations to probe the fine structure of the corona. Recently developed magnetohydrodynamic (MHD) wave theory has shown that the properties of loop oscillations depend on their plasma fine structure. Up to this point, many studies have concentrated solely on the effect of plasma density stratification on coronal loop oscillations. In this paper we develop MHD wave theory which models the effect of an inhomogeneous magnetic field on coronal loop oscillations. The results have the potential to be used in testing the efficacy of photospheric magnetic field extrapolations and have important implications regarding magneto-seismology of the corona
Wavelet transform - artificial neural network receiver with adaptive equalisation for a diffuse indoor optical wireless OOK link
This paper presents an alternative approach for signal detection and equalization using the continuous wavelet transform (CWT) and the artificial neural network (ANN) in diffuse indoor optical wireless links (OWL). The wavelet analysis is used for signal preprocessing (feature extraction) and the ANN for signal detection. Traditional receiver architectures based on matched filter (MF) experience significant performance degradation in the presence of artificial light interference (ALI) and multipath induced intersymbol interference (ISI). The proposed receiver structure reduces the effect of ALI and ISI by selecting a particular scale of CWT that corresponds to the desired signal and classifying the signal into binary 1 and 0 based on an observation vector. By selecting particular scales corresponding to the signal, the effect of ALI is reduced. We show that there is little variation when using 30 and 5 neurons in the first layer, with one layer ANN model showing a consistently worse BER performance than other models, whilst the 15 neuron model show some behaviour anomalies from a BER of approximately 10-3. The simulation results show that the Wavelet-ANN architecture outperforms the traditional MF based receiver even with the filter is matched to the ISI affected pulse shape. The Wavelet-ANN receiver is also capable of providing a bit error rate (BER) performance comparable to the equalized forms of traditional receiver structure
Employing wavelength diversity to improve SOA gain uniformity
In this paper, we propose a wavelength diversity technique for the semiconductor optical amplifier (SOA) to improve the gain uniformity for ultra-high speed optical routers. In such routers, fast SOA gain recovery is required to ensure the minimum gain standard deviation and thus leading to reduction in the system power penalty. The SOA is modeled using a segmentation technique and the detailed theoretical analysis for the model is presented. A direct temporal analysis of the impact of the signal wavelength on the SOA gain is investigated. The SOA gain profile when injected with a burst of input Gaussian pulses for a single wavelength and the proposed wavelength diversity technique are investigated. The operation principle is simulated and the results show a reduction in the gain standard deviation (at 1 mW input power) of 13.1, 11, 8.1, 6.2 and 4.8 dB for the data rates of 10, 20, 40, 80 and 160 Gb/s, respectively
Multi-agency training and the artist (Sharing our experience, Practitioner-led research 2008-2009; PLR0809/032)
The Multi-Agency Team Project approached issues of multi-agency training indirectly by using an artist as a catalyst in a group exercise examining movement and sound in relation to early childhood.
The aim of the research was to run an experiential non-traditional training programme based on using an artist as a catalyst to promote inter-agency dialogue in one setting, Woodlands Park Nursery and Childrenâs Centre, and to analyse the findings.
Eleven participants used this common experiential focus to frame collective research both as a focus group and as individual fieldworkers. The research demonstrated shared professional discourse but also collected judgements relevant to policy issues based on collaborative professional reflection triggered by the exercise.
The findings are presented theoretically in terms of critical discourse analysis using the interpretation-supporting software ATLASti. We next take a further look at the role play exercise in which the group constituted itself as a âHouse of Commons Select Committeeâ before summarizing what theoretical insights might be brought to bear and attempting to draw some provisional conclusions. Some evidence is presented suggesting there is a degree of tension and ambiguity between alterative models of multi-agency working
