  1. SAM: The School Attachment Monitor

    Vo, Dong-Bach; Tayarani, Mohammad; Rooksby, Maki; Huan, Rui; Vinciarelli, Alessandro; Minnis, Helen; Brewster, Stephen A.
    Secure Attachment relationships have been shown to minimise social and behavioural problems in children and boosts resilience to risks such as antisocial behaviour, heart pathologies, and suicide later in life. Attachment assessment is an expensive and time-consuming process that is not often performed. The School Attachment Monitor (SAM) automates Attachment assessment to support expert assessors. It uses doll-play activities with the dolls augmented with sensors and the child's play recorded with cameras to provide data for assessment. Social signal processing tools are then used to analyse the data and to automatically categorize Attachment patterns. This paper presents the current SAM...

  2. A Data Driven Approach to Audiovisual Speech Mapping

    Abel, Andrew; Marxer, Ricard; Barker, Jon; Watt, Roger; Whitmer, Bill; Derleth, Peter; Hussain, Amir
    The concept of using visual information as part of audio speech processing has been of significant recent interest. This paper presents a data driven approach that considers estimating audio speech acoustics using only temporal visual information without considering linguistic features such as phonemes and visemes. Audio (log filterbank) and visual (2D-DCT) features are extracted, and various configurations of MLP and datasets are used to identify optimal results, showing that given a sequence of prior visual frames an equivalent reasonably accurate audio frame estimation can be mapped.

  3. Measuring the Apparent Width of Auditory Sources in Normal and Impaired Hearing

    Whitmer, William M.; Seeber, Bernhard U.; Akeroyd, Michael A.
    It is often assumed that single sources of sound are perceived as being punctate, but this cannot be guaranteed, especially for hearing-impaired listeners. Any impairment that gives a reduction at the periphery in the accuracy of coding fine-scale temporal information must give a slight interaural jitter in the temporal information passed to higher centres, and so would be expected to lead to an effective reduction in the interaural coherence (IC) of any stimulus. This would lead to deficits in locating sounds, but deficits of imprecision, not inaccuracy. In turn, this implies that older hearing-impaired individuals should have a diminished perception...

  4. The Sensitivity of Hearing-Impaired Adults to Acoustic Attributes in Simulated Rooms

    Whitmer, William M.; McShefferty, David; Akeroyd, Michael A.
    In previous studies we have shown that older hearing-impaired individuals are relatively insensitive to changes in the apparent width of broadband noises when those width changes were based on differences in interaural coherence [W. Whitmer, B. Seeber and M. Akeroyd, J. Acoust. Soc. Am. 132, 369-379 (2012)]. This insensitivity has been linked to senescent difficulties in resolving binaural fine-structure differences. It is therefore possible that interaural coherence, despite its widespread use, may not be the best acoustic surrogate of spatial perception for the aged and impaired. To test this, we simulated the room impulse responses for various acoustic scenarios with...

  5. Recording and Analysis of Head Movements, Interaural Level and Time Differences in Rooms and Real-World Listening Scenarios

    Boyd, Alan W.; Whitmer, William M.; Akeroyd, Michael A.
    The science of how we use interaural differences to localise sounds has been studied for over a century and in many ways is well understood. But in many of these psychophysical experiments listeners are required to keep their head still, as head movements cause changes in interaural level and time differences (ILD and ITD respectively). But a fixed head is unrealistic. Here we report an analysis of the actual ILDs and ITDs that occur as people naturally move and relate them to gyroscope measurements of the actual motion. We used recordings of binaural signals in a number of rooms and...

  6. A Deterministic Method for Particle Sorting by Dynamic Acoustic Fields

    Simon, G.; Andrade, M.A.B.; Roolvink, D.; Cormack, P.A.G.; Riehle, M.O.; Bernassau, A.L.
    This paper investigates the dynamic acoustic sorting method from a theoretical perspective. Analytical equations of motion and numerical simulations have been used to optimize parameters for sorting various particle mixtures. The effect of changes in field parameters as frequency or voltage on efficient sorting has been investigated. Experiments have been carried out to verify theoretical findings.

  9. Beautiful Things: Textiles and Fibre Artefacts from an Early Bronze Age Cremation, Whitehorse Hill, England

    Harris, Susanna; Jones, Andy Michael
    The organic finds preserved in a young adult’s burial on Whitehorse Hill, Dartmoor are the first evidence for decorative textiles, braids and baskets in Early Bronze Age Britain, and they transform current understanding of this period. These fabrics are intricately made and show an imaginative use of materials, textures and shape. The layers and wrappings in the burial deposit provide a rare glimpse of the role of organic materials in burials. In this paper, the archaeological evidence is presented and these finds are discussed in their broader technological and aesthetic context.

  10. Array Metasurfaces for Biomedical Sensing at Infra-Red Wavelengths

    De La Rue, Richard M.; Mbomson, Ifeoma G.; Paul, Jharna; Tabor, Sean; Lahiri, Basudev; Sharp, Graham J.; Vilhena, Henrique; McMeekin, Scott G.; Johnson, Nigel P.
    Detection and identification of biomedically significant molecules is an important application in infra-red (IR) spectroscopy. This presentation will consider some of the significant features of the different alternative building-block elements that can be used in array metasurfaces for enhanced detection sensitivity. The presentation will also address techniques and issues associated with the deposition and localisation of biological and organic chemical molecular material for detection and measurement using IR spectroscopy.

  11. Moving Beyond the Virtual Museum: Engaging Visitors Emotionally

    Perry, Sara; Roussou, Maria; Economou, Maria; Pujol-Tost, Laia; Young, Hilary
    In this paper, we firstly critique the state of the art on Virtual Museums (VM) in an effort to expose the many opportunities available to enroll these spaces into transformative and engaging cultural experiences. We then outline our attempts to stretch beyond the usual VM in order to connect it to visitors in a measurably emotional, participatory, interactive and social fashion. We discuss the foundations for a conceptual framework for the creation of VMs, grounded in a user-centered design methodology and related design and evaluation guidelines. We then introduce two main cultural heritage sites, which are used as case studies at the core of our efforts, and conclude by describing the...

  12. Designing Vibrotactile Widgets with Printed Actuators and Sensors

    Frisson, Christian; Decaudin, Julien; Pietrzak, Thomas; Ng, Alexander; Poncet, Pauline; Casset, Fabrice; Latour, Antoine; Brewster, Stephen A.
    Physical controls are fabricated through complicated assembly of parts requiring expensive machinery and are prone to mechanical wear. One solution is to embed controls directly in interactive surfaces, but the proprioceptive part of gestural interaction that makes physical controls discoverable and usable solely by hand gestures is lost and has to be compensated, by vibrotactile feedback for instance. Vibrotactile actuators face the same aforementioned issues as for physical controls. We propose printed vibrotactile actuators and sensors. They are printed on plastic sheets, with piezoelectric ink for actuation, and with silver ink for conductive elements, such as wires and capacitive sensors....

  13. Atomistic to Circuit Level Modeling of Defective Doped SWCNTs with Contacts for On-Chip Interconnect Application

  14. Non-Maleficience: Professional Practice in Poland

    Bohdan Lewoc, Józef; Hersh, Marion; Fitzgibbon, Mike
    This paper discusses professional practice with regards to the role of translators and interpreters in contemporary Poland. One of the significant changes currently taking place in Poland and many other countries is increasing integration with Europe and the world as a whole. Translators and interpreters have a very important role in this integration process. They are at the forefront of talks and discussion about integration and increasing interaction between Poland and the rest of the world, including in technology development and transfer. Ethical behaviour by both translators and the organisations that employ them, whether on a short or long term...

  15. Professional Ethics and Social Responsibility: Military Work and Peacebuilding

    Hersh, Marion
    The paper considers a number of important questions related to the involvement of engineers in peacebuilding and military work, including the preference of many countries for high tech weapons based security over peacebuilding, whether and in what circumstances, if any, it is justified for engineers to be involved in military work; and how engineers can persuade their colleagues to apply their skills to support peacebuilding. It is introduced by an overview of what is meant by the term military work and the extent and consequences of the use of military technology worldwide. This is followed by the applications of different...

  16. Ethical Engineering and Respect for The ‘Other’

    Hersh, Marion
    Engineers have a very important role and responsibility in shaping modern society. Diversity amongst engineers is important in fulfilling this responsibility and ensuring that the creativity and needs of the whole population are taken account of. However, only a small percentage of engineers are female and very few of them are disabled. The paper discusses the experiences of women and disabled engineers in the context of othering and considers the way in which the existence of binary divides facilitates marginalisation and exclusion. It also discusses the need to involve end-users in design and development and education to encourage this, with...

  17. Numerical Implementation of a Critical State Model for Soft Rocks

    Lloret-Cabot, Marti; Pineda, Jubert A.; Sheng, Daichao
    This paper details the basic tasks for the numerical implementation of a simple elasto-plastic critical state model for bonded materials (i.e. soft rocks-hard soils) into the finite element program SNAC developed at the University of Newcastle in Australia. The first task described focusses on the derivation of the incremental constitutive relationships used to represent the mechanical response of a bonded/cemented material under saturated conditions. The second task presents how these stress-strain relations can be numerically integrated using an explicit substepping scheme with automatic error control. The third task concentrates on the verification of the substepping algorithm proposed. The model used...

  18. Performance Maps: a Simple Way to Verify the Correctness of Explicit Integration Algorithms with Automatic Substepping

    Lloret-Cabot, Marti; Sloan, Scott W.; Sheng, Daichao; Abbo, Andrew J.
    Based on the known order of local accuracy of a numerical method, Lloret-Cabot, Sloan, Sheng and Abbo proposed a useful form of plotting the computational outcomes obtained from the integration of the stress-strain relations when using explicit substepping integration schemes. This new form of plotting the numerical results (performance maps) is useful for verification purposes in problems where an analytical solution is difficult to find. The applicability of the performance maps to check specific computational aspects during the numerical integration of the stress-strain constitutive relationships of a model is extended further in this paper for explicit substepping algorithms that automatically...

  19. Deposition of Organic Molecules on Gold Nanoantennas for Sensing

    Kuzmiak, Vladimír; Markos, Peter; Szoplik, Tomasz; Paul, Jharna; McMeekin, Scott G.; De La Rue, Richard M.; Johnson, Nigel P.
    The deposition of organic molecules on gold nanoantennas is reported through chemisorption for sensing in the midinfrared (mid-IR) spectral range. The specific nanostructures are gold asymmetric-split ring resonators (A-SRRs) based on circular-geometry with two different ‘arc’ lengths. The plasmonic resonant coupling technique was used to match the vibrational responses of the targeted molecules for their enhanced detection. Gold nanostructures are functionalised through chemisorption of octadecanethiol (ODT) in ethanol solution. The molecular vibrational responses were measured using a microscope coupled Fourier Transform Infrared (FTIR) spectroscopy. The experimental findings are closely supported using FDTD simulation. The modified nanoantennas surfaces are capable of...
