Low-fi skin vision: A case study in rapid prototyping a sensory substitution system

We describe the design process we have used to develop a minimal, twenty vibration motor Tactile Vision Sensory Substitution (TVSS) system which enables blind-folded subjects to successfully track and bat a rolling ball and thereby experience 'skin vision'. We have employed a low-fi rapid prototyping approach to build this system and argue that this methodology is particularly effective for building embedded interactive systems. We support this argument in two ways. First, by drawing on theoretical insights from robotics, a discipline that also has to deal with the challenge of building complex embedded systems that interact with their environments; second, by using the development of our TVSS as a case study: describing the series of prototypes that led to our successful design and highlighting what we learnt at each stage

Emerging imaging techniques in spondyloarthritis dual-energy computed tomography and new MRI sequences

Imaging of the sacroiliac joint plays a critical role in the classification of patients with axial spondyloarthritis. New imaging techniques are emerging, changing the way clinicians look at the sacroiliac joint. This article introduces the novel techniques in imaging of spondyloarthritis, including dual-energy computed tomography and new MRI sequences, with a focus on the imaging of bone marrow edema and erosions of the sacroiliac joint

Issues of Socioeconomic Class in Barbara Cartland’s A Duel of Hearts and Catherine Cookson’s The Menagerie

In this paper, we examine the role that socioeconomic class has to play in two novels of romance genre fiction: Barbara Cartland’s A Duel of Hearts and Catherine Cookson’s The Menagerie. Published in the years following the Second World War, these novels are written in the style which, while observing the central conventions of romance fiction, additionally depict the experiences of the central characters through the lens of their respective class: aristocracy versus working-class. This article will compare, contrast and analyze the way in which issues of class are presented by the authors in their respectivenovels

The Occult as a rejection of Darwinism in Arthur Machen\u27s The Great God Pan and H.P.Lovecraft\u27s Case of Charles Dexter Ward

In this paper,the issues concerning manifestations of Darwinism and the occult in Gothic fiction will be explored. On the Origin of Species was published by Charles Darwin in 1859. His study of biology and the development of the theory of natural selection called into question Chiristianity\u27s established beliefs on the creation of mankind. This rather more prosaic determination of the origins of mankind was difficult for some Christians to accept. This brief study will examine the relationship between occult and Darwinism in two examples of Gothic horror fiction

Absorbance of the OH Radical in a Specific Wavelength Interval Near 309A

The absorbance of the OH radical as a function of optical density was studied by computing the absorbance for an incident radiation in the wavelength interval 3089A-3097A. The absorbance was studied for 3 different temperatures and various values of the parameters specifying the line shapes and magnitude of the spectral absorption coefficient

MEASUREMENT AND ANALYSIS OF SEA WAVES NEAR A REFLECTIVE STRUCTURE

Merged with duplicate record 10026.1/2047 on 06.20.2017 by CS (TIS)Methods and equipment for the measurement of ocean waves were reviewed and their suitability assessed for the aim of this project: field measurement of sea waves near a reflective coastal structure such as a breakwater. None was found to be suitable. The functional and performance objectives are set out for a new system. The evolution of the final design, based on an array of pressure sensors, is described. The whole system is intended to be deployed on the sea-bed. It is fully self contained and independent of shore based services. Located away from the surf zone it is well placed to survive storm conditions and unauthorised interference. Theoretical methods for the re-construction of surface elevation records from measured sub-surface pressures, and the experimental findings of other workers, are presented. Available methods of estimating the wave directional spectrum from a spatial array of surface elevation records are reviewed, and the most appropriate one implemented. The system has given extensive service at a number of coastal defence sites. The results of subsequent analysis of selected data sets are presented in detail. They show the pronounced nodal structure in amplitude expected in the presence of wave reflection, clearly demonstrating that a single point measurement is likely to give misleading estimates of incident wave height. For near-calm to moderate, shore-normal incident wave conditions the results were found to agree with theoretical predictions both of wave height as a function of distance offshore, and of the structure's frequency-dependent reflection coefficient. For rougher conditions, in which both theoretical and physical models are less applicable, the results agreed with visual observations
