Co-designing Speakers Corner
No full text“What might a twenty-first century Speakers’ Corner look like and how should the design process ensure that local people can contribute?”
The paper considers this question through describing a three year collaboration between MA Creative Practice for Narrative Environments (MACPfNE) at CSM, and the Speakers’ Corner Trust (SCT). SCT is a charity promoting public debate and active citizenship to revitalise civil society in the UK. It pursues its aims by forming local Committees which ‘own’ and steer the establishment of Speakers’ Corners as platforms for public engagement. MACPfNE is an innovative course that encourages multidisciplinary collaboration and the use of narrative as a tool to develop user focused environments.
Working closely with SCT, MACPfNE staff and students developed a methodology whereby communities co-create their own physical manifestation of Speakers’ Corner to suit needs and environment. The methodology and its theoretical foundation were developed through a series of live projects, including: a generic mobile Speakers’ Corner prototype, tested at the Global Forum for Freedom of Expression in Oslo; the co-design with local school children, followed by implementation of London’s second Speakers’ Corner in a community park in North London; and a pilot project to co-design Speakers’ Corner in every school playground
Integrated corner mirrors physically micromachined in silica-on-silica
No full textIn integrated photonics, compact redirection of light can be achieved by corner (turning) mirrors, providing a route to higher density optical components. Corner mirrors have been demonstrated in both silicon-on-insulator and hollow waveguides with reported losses of 0.9dB [1] and 0.8dB [2] respectively. We report a novel method of fabricating mirrors on a silica-on-silicon substrate. The method utilises the complementary techniques of physical micromachining and direct UV writing, both providing rapid prototyping outside the cleanroom environment
Radiation characteristics of corner reflector antennas.
No full textPhDThis thesis presents a study of the radiation characteristics of corner reflector
antennas. The influence of the design parameters on the radiation characteristics are
assessed using an analytical method and the Finite Difference Time Domain (FDTD)
method.
The FDTD method for corner reflector antennas which are electrically small to
medium sized antennas is developed in detail. The important subject of the Absorbing
Boundary Conditions (ABCs) is studied including a study of Mur ABC and Perfectly
Matched Layers. It is shown that both methods reduce the reflections from the
boundaries sufficient so that the far-field radiation pattern can be computed
accurately.
An analytical solution to compute the far-field radiation pattern for infinite comer
reflector antennas is derived and used to understand the radiation mechanisms. Based
on those results, the FDTD method is used to conduct a parametric study on finite
sized comer reflector antennas. Experimental antennas have been built and measured
in order to verify the computational predictions. Very good agreement is reported
The novel idea of a variable beam-width comer reflector antenna is developed and
practical designs of such an antenna are presented. The principle is to design the
comer reflector antenna such that the beam-width of the antenna can be precisely
modified. Data on the gain and beam-width are presented. This has been done both by
computational and by an experimental model.
The influence on the performance of the comer reflector antenna when substituting
the solid reflector plates by rods has been investigated. The computational predictions
have been verified by measurements of an experimental antenna. Very good
agreement has been achieved.
III[
The possibility of modifying the shape of the comer reflector antenna is investigated.
It is shown that a modified comer reflector antenna with less depth produces the same
far-field pattern as a standard corner reflector antenna. It is also shown that the
performance of small aperture size corner reflector antennas is superior to a
cylindrical parabolic reflector antenna
The influence of social processes on the timing of cancer diagnosis: a research agenda
No full textThis paper sets out to review the influence of social processes on the timing of the diagnosis of cancer and to explore the potential for promoting earlier diagnosis by addressing social factors that influence symptom recognition and the diagnostic process. Social processes refer to the means by which culture and social organisation may impact on timely cancer diagnosis. The paper calls for concerted action around an important and developing research agenda that may prove highly valuable in the quest to secure prompt diagnosis for cancer and through it improved outcomes for individuals. <br/
Older people, care, and cancer: A critical perspective
No full textCare of older people with cancer has received relatively little attention in the literature and this area of caring practice has yet to be firmly established in professional discourse. References to the increasing proportion of older people in the population are common, as are references to the problems associated with old age, whether these are seen as medical, or as inevitable consequences of natural processes. Health care for older people has sometimes been reported to be routinized or basic, and as taking little account of individual perspectives, and the ‘discourse of senescence’ represents a tendency to understand old age and the aged body in terms of degeneration and deterioration. Here, it is argued that older people are often portrayed as separate and diminished, and have little control over the definition of themselves as users of health services. This represents a constraint upon the possibilities of caring practice. Divesting ourselves of the ‘discourse of senescence’ may be a fundamental part of developing caring practice for older people with cancer in the future
ECFRNet: Effective corner feature representations network for image corner detection
No full textInterest points (corners and blobs) play an important role in computer vision tasks such as image matching, image retrieval, and 3D reconstruction. Existing deep learning based interest point detection methods mainly focus on the interest point detection with high repeatability under image affine transformations while neglecting the importance of the characteristics of interest points. This will affect the detection and localization accuracy of interest points. In this paper, we design an effective corner feature representations network based on the characteristics of corners. The designed network has the ability to effectively learn corner feature information from images. A novel loss function is proposed to minimize the localization error between the corner positions of the original image block and the transformed image blocks. Furthermore, a novel corner detection architecture is proposed. The criteria on detection accuracy, localization accuracy, average repeatability, region repeatability, and image matching score are used to evaluate the proposed method against fourteen state-of-the-art methods. The experimental results show that the proposed performs significantly better than the state-of-the-arts.No Full Tex

An Innovative Experimental Study of Corner Radius Effect on Cutting Forces
No full textThe cutting forces are often modelled using edge discretisation methodology. In finish turning, due to the smaller corner radii, the use of a local cutting force model identified from orthogonal cutting tests poses a significant challenge. In this paper, the local effect of the corner radius on the forces is investigated using a new experimental configuration: corner cutting tests involving the tool nose. The results are compared with inverse identifications based on cylindrical turning tests and elementary cutting tests on tubes. The results obtained from these methods consistently show the significant influence of the corner radius on the cutting forces
