Modelling Methods for the Highly Dispersive Slinky Spring: A Novel Musical Toy
No full textABSTRACT The 'Slinky' spring is a popular and beloved toy for many children. Like its smaller relatives, used in spring reverberation units, it can produce interesting sonic behaviors. We explore the behavior of the 'Slinky' spring via measurement, and discover that its sonic characteristics are notably different to those of smaller springs. We discuss methods of modeling the behavior of a Slinky via the use of finite-difference techniques and digital waveguides. We then apply these models in different structures to build a number of interesting tools for computer-based music production
Pacific SST influence on spring precipitation in Addis Ababa, Ethiopia
No full textRecent periods of drought in Ethiopia and other parts of East Africa have highlighted the growing importance of producing reliable forecasts of seasonal precipitation. Key in deriving such forecasts is a good understanding of the atmospheric and oceanic drivers of different precipitation regimes. In Ethiopia and other parts of East Africa, interannual variability of precipitation depends on variations in sea surface temperature (SST) and atmospheric circulation on both regional and global scales. Links between summer precipitation in Ethiopia and large-scale modes of climate variability such as El Niño Southern Oscillation (ENSO) have previously been established but the influence of global SST on spring precipitation has not yet been fully explored. Here, we analyse the links between Pacific SST and precipitation in Addis Ababa, Ethiopia for a century-long period (1900–2004). A tripole correlation pattern between spring precipitation and SST in the Pacific basin is found. We develop regression-based models to estimate spring precipitation from Pacific SST with a lead time of two to three months. When subject to cross-validation, models based on principal component multiple linear regression (PC-MLR) calibrated on Pacific SST during December show substantial skill in reproducing observed temporal variability in Addis Ababa precipitation during February (r?=?0.48) and March (r?=?0.40), and the period spanning February to April (r?=?0.44). Our findings suggest that the inclusion of Pacific SST in predictive models may benefit drought forecasting across Ethiopia
Interview with Jonathan Darling, author of Systems of Suffering: Dispersal and the Denial of Asylum (2022)
Get PDFThis conversation between Jonathan Darling and Sarah M. Hughes focuses on Darling’s recently published book Systems of Suffering: Dispersal and the Denial of Asylum (2022). Based on research conducted over the course of six years, Systems of Suffering examines the emergence, development, and implications of the dispersal system in the UK. This market-based system of asylum governance is a process that distributes asylum seekers to predominantly urban areas and, Darling argues, represents a form of “distributed violence that is cumulative and incapacitating, and governs through the exhaustion of its critics and subjects” (p. 3). As the conversation unfolds, Darling talks about the implications of the rapidly shifting legal and policy landscape in the UK for the asylum dispersal and the challenges but, he suggests, political urgency of continuing to research it
Jonathan Edwards a life
No full text"Jonathan Edwards (1703-1758) is a towering figure in American history. A controversial theologian and the author of the famous sermon Sinners in the Hands of an Angry God, he ignited the momentous Great Awakening of the eighteenth century." "In this biography, Jonathan Edwards emerges as both a great American and a brilliant Christian. George M. Marsden evokes the world of colonial New England in which Edwards was reared - a frontier civilization at the center of a conflict between Native Americans, French Catholics, and English Protestants. Drawing on newly available sources, Marsden demonstrates how these cultural and religious battles shaped Edwards' life and thought. Marsden reveals Edwards as a complex thinker and human being who struggled to reconcile his Puritan heritage with the secular, modern world emerging out of the Enlightenment. In this, Edwards' life anticipated the deep contradictions of our American culture."--BOOK JACKET
Towards a Framework for Developing Mobile Agents for Managing Distributed Information Resources
No full textDistributed information management tools allow users to author, disseminate, discover and manage information within large-scale networked environments, such as the Internet. Agent technology provides the flexibility and scalability necessary to develop such distributed information management applications. We present a layered organisation that is shared by the specific applications that we build. Within this organisation we describe an architecture where mobile agents can move across distributed environments, integrate with local resources and other mobile agents, and communicate their results back to the user

Role of plasma temperature and residence time in stagnation plasma synthesis of c-BN nanopowders
No full textThe synthesis of cubic boron nitride (c-BN) nanoparticles is examined experimentally by introducing borane ammonia precursor into a thermal plasma oriented in a stagnation point geometry, where nanoparticles are formed in the flow field upon reaching a cold substrate. The quasi-one dimensional flow field allows for correlating the plasma temperature and residence time to the final particle phase, morphology, size, and purity. Constant temperature and residence time cases are studied to assess the parameter’s affect on the resulting particle characteristics. The as-synthesized nanoparticles are characterized by high-resolution transmission electron microscopy (HRTEM) and x-ray diffraction (XRD). Cubic structured particles are synthesized at plasma temperatures of 3000-8000K and precursor decomposition times ≥0.030s. The highest purity samples are produced at a plasma temperature and residence time of 6500K and 0.075s, respectively. Samples with lower c-BN content are observed with higher percentages of hexagonal and amorphous phases. The particle morphology shifts from spherical agglomerates to faceted shapes as c-BN purity increases. Also, particle size undergoes an increase in nominal size. The resulting phase and purity is proposed to be governed by growth mechanisms that result in high-energy particle-particle interactions where the energy transferred is sufficient for atomic re-alignment into a denser phase.M.S.Includes bibliographical referencesby Jonathan M Doyl

'Giving honour to the Spirit' : a critical analysis and evaluation of the doctrine of pneumatological union in the Trinitarian theology of Jonathan Edwards in dialogue with Karl Barth
No full textThe extent to which the 'honour' of the Spirit influenced the theology of
Jonathan Edwards is a hitherto underdeveloped theme. Against a backdrop of
Patristic thought and in dialogue with the theology of Karl Barth, evaluation is
made of pneumatological union in Edwards' Trinitarian theology as this centres
on the nature and inter-relatedness of the 'three unions' that characterize his
theology: the union of the three Persons of the Trinity, the union of the saints
with God, and the union of the divine and human natures of Christ.
Edwards' seeks to honour the Spirit as the mutual love of the Father for the Son
within his Augustinian, Lockean model of the immanent Trinity, and as 'Person'
in the economy. The challenges of doing so within the limits of this
psychological model of the Trinity are evaluated in dialogue with the
Cappadocian Fathers and Barth.
In a manner patterned after union in the Trinity, Edwards gave prominence to the
concept of the pneumatological union of the saints with God in Christ, in
fulfilment of the self-glorifying purpose of God in creation and redemption.
Edwards' experiential theology of conversion, and his elevation of subjective
sanctification by the Spirit over objective justification in Christ, for assurance, is
contrasted with Barth's greater emphases on the Christological union of God
with humanity and objective justification in Christ. Barth's more contemplative
approach is contrasted with the overly introspective spirituality of Edwards.
Edwards' view of the role of the Spirit in the hypostatic union of God with
humanity in Christ, which is reflective of the other unions, is also evaluated in
light of Patristic, Reformed-Puritan and Barthian thought on the nature of the
humanity Christ assumed, and the doctrine of the vicarious humanity of Christ. A
more emphatic incarnational emphasis may have saved Edwards' Spirit-
honouring spirituality from an anthropocentricity which is ironical given that the
glory of God is his ontic doxological concern
