Supporting Knitwear Design Using Case-Based Reasoning

Organised by: Cranfield UniversityKnitwear design is a creative activity that is hard to automate using the computer. The production of the associated knitting pattern, however, is repetitive, time-consuming and error-prone, calling for automation. Our objectives are two-fold: to facilitate the design and to ease the burden of calculations and checks in pattern production. We conduct a feasibility study for applying case-based reasoning in knitwear design: we describe appropriate methods and show how they can be implemented.Mori Seiki – The Machine Tool Compan

Preservation through access: the AHDS performing arts collections in ECLAP and Europeana

This poster provides an overview of the ongoing rescue of valuable digital collections that had been taken down and consequently lost to general access. The University of Glasgow was home to the Arts and Humanities Data Service Performing Arts (AHDS Performing Arts) [1], one of the five arts and humanities data centres that constitute the Arts and Humanities Data Service (AHDS). Since 1996 AHDS supported the creation, curation, preservation and reuse of digital materials for the UK Arts and Humanities research and teaching community. AHDS Performing Arts, based in Glasgow, supported research, learning and teaching in music, dance, theatre, radio, film, television, and performance for thirteen years. Working with the AHDS Executive, relevant performing arts collections have been ingested, documented, preserved, and where possible made available via the AHDS Cross Search Catalogue and Website to researchers, practitioners, and the general public. Furthermore strong relationships were developed with research and teaching community upon a scoping study investigating user needs [2]. In 2007 the co-funders of the AHDS - Arts and Humanities Research Council (AHRC) for the UK and the Joint Information Systems Committee (JISC) - withdrew their funding. A detailed risk assessment report was produced in response to the withdrawal of core funding [3], but to no avail. When the AHDS funding stopped, online access to these cultural resources eventually became discontinued [4]. In 2010, the School of Culture and Creative Arts at the University of Glasgow joined the EU-funded ECLAP project to ensure that at least part of these resources could be accessible for the long term by scholars and practitioners in the performing arts arena, and by the general public. Below we briefly describe the ECLAP project, the AHDS Performing Arts collections progressively available through it and some thoughts on providing preservation through access for this type of digital cultural resources

Mainstream parallel array programming on cell

We present the E] compiler and runtime library for the ‘F’ subset of the Fortran 95 programming language. ‘F’ provides first-class support for arrays, allowing E] to implicitly evaluate array expressions in parallel using the SPU coprocessors of the Cell Broadband Engine. We present performance results from four benchmarks that all demonstrate absolute speedups over equivalent ‘C’ or Fortran versions running on the PPU host processor. A significant benefit of this straightforward approach is that a serial implementation of any code is always available, providing code longevity, and a familiar development paradigm

A study of the impact of substituting Warfarin with Direct Oral Anticoagulants (DOAC), in Atrial Fibrillation (AF) patients over 65 years old: The Patients’ and Clinicians’ Perspectives.

The need for this research was identified during the researcher’s daily practice in her Haematology clinic in London. The clinic specialises in anticoagulated patients, particularly those with the condition of Atrial Fibrillation. The researcher noted that while extensive research had been undertaken into the medical issues associated with the established oral anticoagulant Warfarin, the newer medication referred to as Direct Oral Anticoagulants (DOACs) was less broadly studied. Importantly, little was known about how patients coped on a daily basis with this new treatment. Furthermore, the practical and social impact of a switch from Warfarin to a DOAC for clinical reasons had rarely been studied from the patient’s perspective. An inductive, mixed-method research study was set up comprising two questionnaires and individual interviews. A sample of 56 patients, aged 65ys and over, grouped by age and sex, were selected from the clinic. The first questionnaire was a Perceived Stress Scale (PSS), which explored the participants’ levels of stress at three time points: the switch over, then at 30 and 90 days. Concurrently a Medical Outcome Study (SF-36), a health survey was administered. Twenty of these patients were also interviewed by the researcher on two occasions, at the switch over then at 90 days. Thematic analysis was undertaken on the transcripts to identify themes across the patients’ responses. The findings showed that the switch to a DOAC had a positive impact on most of the respondents. They felt liberated from several of the constraints of taking Warfarin, for example, of not needing regular clinical monitoring so being able to travel further and more often, and eating a wider, healthier diet. The patients also reported feeling less stressed in general at the 30 day point, this was sustained over the remainder of the study period. There were some small differences between the ages, the older patients reported fewer benefits from the switch, although remaining positive about the experience. No significant difference was noted between the sexes. Patients highlighted the importance of personal resilience throughout, but that good GP support was also crucial in their continued wellbeing

Artificially created stimuli produced by a genetic algorithm using a saliency model as its fitness function show that Inattentional Blindness modulates performance in a pop-out visual search paradigm

Salient stimuli are more readily detected than less salient stimuli, and individual differences in such detection may be relevant to why some people fail to notice an unexpected stimulus that appears in their visual field whereas others do notice it. This failure to notice unexpected stimuli is termed 'Inattentional Blindness' and is more likely to occur when we are engaged in a resource-consuming task. A genetic algorithm is described in which artificial stimuli are created using a saliency model as its fitness function. These generated stimuli, which vary in their saliency level, are used in two studies that implement a pop-out visual search task to evaluate the power of the model to discriminate the performance of people who were and were not Inattentionally Blind (IB). In one study the number of orientational filters in the model was increased to check if discriminatory power and the saliency estimation for low-level images could be improved. Results show that the performance of the model does improve when additional filters are included, leading to the conclusion that low-level images may require a higher number of orientational filters for the model to better predict participants' performance. In both studies we found that given the same target patch image (i.e. same saliency value) IB individuals take longer to identify a target compared to non-IB individuals. This suggests that IB individuals require a higher level of saliency for low-level visual features in order to identify target patches

A two-stage magnetic refrigerator for astronomical applications with reservoir temperatures above 4 K

We propose a novel adiabatic demagnetization refrigerator (ADR) to produce temperatures as low as 100 mK starting from a high temperature reservoir between 4 and 8 K. The high temperature reservoir for the ADR can be provided by a mechanical cooler or an unpumped liquid helium bath. This refrigerator can be used to cool bolometric infrared detectors for low background astronomy from mountain tops, balloons or satellites as well as to cool cryogenic x-ray detectors. The two-stage ADR consists of a single magnet with a paramagnetic chromic-cesium-alum (CCA) salt pill to produce the low temperature and paramagnetic gadolinium-gallium-garnet (GGG) as the first stage to intercept heat from the high temperature reservoir. Thermal contact between the paramagnets and the reservoir during magnetization is made with a mechanical heat switch. The ADR is suspended with Kevlar chords under tension for high mechanical stiffness and low parasitic heat leak. In a single cycle, the ADR maintains a temperature of 100 mK for 10 to 100 hours. This time depends strongly on the magnetic field and reservoir temperature but not on the volume of the paramagnetic material as long as the heat leak is dominated by the suspension
