A Fixed Grid Method for Capturing the Motion of Self-Intersecting Interfaces and Related PDEs
No full textMoving interfaces that self-intersect arise naturally in the geometric optics model of wavefront motion. Ray tracing techniques can be used to compute these motions, but they lose resolution as rays diverge. In this paper we develop a new numerical method that maintains uniform spatial resolution of the front at all times. Our approach is a fixed grid, interface capturing formulation based on the Dynamic Surface Extension method of Steinhoff and Fan [10]. The new methods can treat arbitrarily complicated self intersecting fronts, as well as refraction, reflection and focusing. We also further extend this approach to curvature dependent front motions, and the motion of filaments. We validate the new methods with numerical experiments.

The flower of kings : a study of the Arthurian legend in England between 1485 and 1835
No full textThis book provides for the first time in over seventy-five years a single, comprehensive, up-to-date account of the fortunes of the Arthurian story in England from the time of Malory to the beginning of the Victorian period. After a brief survey of the earliest forms of the legend, the author examines the slow decline of the myth in the English Renaissance until its near extinction by the middle of the eighteenth century, despite the attraction which it held for Spenser, Drayton, Jonson, and Dryden. Succeeding chapters show that even through the legend's vitality was reduced by both Dryden and Fielding, the Romantic movement brought Arthur back to life, Minor figures such as William Hilton and Richard Hole, together with Scott and Wodsworth, though they did not produce great poems on the subject, are shown nevertheless to have responded seriously to the legend. The book concludes with an England ready in its interests and sympathies for the great flowering of the Arthurian story among the Victorians. Throughout this survey, which covers both the major figures and a number of hitherto unexamined minor authors, James D. Merriman is concerned with several questions of considerable interest both scholarly and critical
Because We Are Poor: Irish Theatre in the 1990s
No full textThroughout the twentieth century, Irish theatre was fully engaged with the pressing questions of independence – how to achieve it, and how the gap between what was desired and what was settled for might be addressed. In Because We Are Poor, Victor Merriman reads Ireland’s postcoloniality as a state of critical desire for a postponed project of decolonisation in Independent Ireland. He develops insights from Awam Amkpa, Luke Gibbons, Peadar Kirby, Joe Lee, David Lloyd and others to argue that Irish theatre is staged in a neo-colonial social order, dominated by economic analyses and public policies designed to secure the position of indigenous elites, usually at the expense of the majority of Irish people. Theatre emerges as a key site in which the contradictions arising from frustrated but enduring desires are embodied, enacted and enabled. During the 1990s, the state’s monopoly on public discourse in Independent Ireland comes under severe pressure, with hitherto marginal concerns appropriating public space and demanding to be heard. Irish theatre responds to the range and diversity of those voices, to the extent that the Review of Theatre in Ireland (1995-1996) envisages a National Theatre in dialogue with a Theatre of the Nation. The expanded theatrical activity of the 1990s is the focus of Because We Are Poor, and the author’s intimate involvement in that moment, as scholar, practitioner, and policy-maker makes the analysis offered here especially compelling. This book brings together concerns which the author has worked to articulate in Irish theatre criticism. It critiques contemporary appropriations of the postcolonial, or post-colonial, among scholars of Irish drama, and proposes a nuanced postcolonial critical practice, challenging critical vocabularies applied to Irish drama. The book addresses the role, crises and potential of Irish theatre, as the cultural and political consequences of globalisation manifest themselves

Woodswoman walking: a journey toward solitude
No full text2014 Summer.On September 1, 2013, Joannah Merriman, not at all a hiker, not really an outdoor athlete of any sort, set out to walk the Camino de Santiago from the French Pyrenees to Santiago de Compostela. A card-carrying member of AARP, armed with a passport, a camera, a journal, and a deep desire to find solitude for longer than a day or a week, she began an 800 kilometer "walk" along the Camino Frances, alone and with the many other peregrinos who happened to be on the path during that time period. Throughout the six weeks of her personal journey, she discovered that the walk was much more difficult than she had imagined, and that she was much stronger than she had ever thought she might be. She met and embraced the Spanish countryside, her fellow trekkers, gratitude for a bed at night, sometimes in a room with up to a hundred fellow pilgrims, and most important, herself
Graph MBO on Star Graphs and Regular Trees.: With Corrections to DOI 10.1007/s00032-014-0216-8
No full textThe graph Merriman–Bence–Osher scheme produces, starting from an initial node subset, a sequence of node sets obtained by iteratively applying graph diffusion and thresholding to the characteristic (or indicator) function of the node subsets. One result in [14] gives sufficient conditions on the diffusion time to ensure that the set membership of a given node changes in one iteration of the scheme. In particular, these conditions only depend on local information at the node (information about neighbors and neighbors of neighbors of the node in question). In this paper we show that there does not exist any graph which satisfies these conditions. To make up for this negative result, this paper also presents positive results regarding the Merriman–Bence–Osher dynamics on star graphs and regular trees. In particular, we present sufficient (and in some cases necessary) results for the set membership of a given node to change in one iteration.Mathematical Physic
