Abstract:
The woman in … quotes from Yeats's "The Tower," a poem in which Yeats, who was familiar with séances, recalls the dead. "The Tower" is closely related to Yeats's book of occult philosophy, , in which he refers to 'phantasmagoria,' projections of images of ghosts, in discussing "dreaming back" by the Spirit. By repeatedly reproducing scenes, M's voice, called V, seems to be dreaming back a solitary séance by M, conducted by his past self to see the woman without. For Beckett, television thus produced a version of Yeats's phantasmagoria, a projection of the inner ghost outward.

A planar point set S is an (i, t)set of ghost chimneys if there exist lines H0, H1,…,Ht-1 such that the orthogonal projection of S onto Hj consists of exactly i + j distinct points. We give upper and lower bounds on the maximum value of t in an (i, t) set of ghost chimneys, showing that it is linear in i.

Abstract:
The practical applicability of anomalous scattering and null-domain ghost corrections for fibre textures is theoretically evaluated. For a hypothetical asymmetric orientation distribution of quartz-like BPO4 highly absorpting crystals, slightly asymmetric anomalous scattering pole figures are predicted. On the basis of projection relations among orientation distribution functions and inverse pole figures, the special characteristics of the null-domain method for fibre textures are discussed, with the suggestion of a practical procedure to estimate (in favourable cases) an upper limit for ghosts effects.

Abstract:
This paper discusses an implementation of a multimedia projection system with two synchronized video sources, based on the Raspberry Pi single board computer systems. The system is primarily intended for various projections in presentation of historical and cultural heritage, although it can be used for many other related purposes. The considered multimedia system has two projection surfaces - a horizontal projection plane and a 45° inclined special glass projection plane which creates the hologramlike Pepper’s Ghost effect. Each plane displays a separate high-definition video obtained from the corresponding Raspberry Pi. Synchronization of presentations is achieved using cu stom connection throu gh the general purpose input/output (GPIO) connector of the Raspberry Pi and the wiringPi interface library. As valuable aspects of the system, we can point out the following. From the practical point of view, the system has low cost due to the use of Rasp berry Pis. Generation of a holograp hic effect, as well as larger flexibility in creating the contents of the presentations due to the two projection surfaces, are additional attractive features.

Abstract:
Millimeter-wave SAR (Synthetic Aperture Radar) imaging is widely studied as a common means of RF (Radio Frequency) imaging, but there are problems of the ghost image in Sparsely-Sampled cases and the projection of multiple targets at different distances. Therefore, a robust imaging algorithm based on the Analytic Fourier Transform is proposed, which is named mmSight. First, the original data are windowed with Blackman window to take multiple distance planes into account; then, the Analytic Fourier Transform that can effectively suppress the ghost image under Sparsely-Sampled is used for imaging; finally, the results are filtered using a Mean Filter to remove spatial noise. The experimental results show that the proposed imaging algorithm in this paper, relative to other algorithms, can image common Fully-Sampled single target, hidden target, and multiple targets at the same distance, and solve the ghost image problem of single target in the case of Sparsely-Sampled, as well as the projection problem of multiple targets at different distances; the Image Entropy of the mmSight is 4.6157 and is on average 0.3372 lower than that of other algorithms. Compared with other algorithms, the sidelobe and noise of the Point Spread Function are suppressed, so the quality of the image obtained from imaging is better than that of other algorithms.

Abstract:
We present the classical and quantum theory of the spinning conformal particle. This is a model with manifestly O(2, 4) (conformal) invariance, and it describes both massive and massless particles of arbitrary spin depending on the projection to Minkowski space. We perform both an ordinary BRST quantization and an extended one including the anti-BRST symmetry. It is shown that anti-BRST invariance is necessary to ensure ghost decoupling and make the quantization of the model consistent.

Full text
Abstract:
A model-based imaging framework is applied to correct the target distortion seen in microwave imaging through a periodic wall structure. In addition to propagation delays caused by the wall, it is shown that the structural periodicity induces high-order space harmonics leading to other ghost artifacts in the through-wall image. To overcome these distortions, the periodic layer Green’s function is incorporated into the forward model. A linear back-projection solution and a nonlinear minimization solution are applied to solve the inverse problem. The model-based back-projection image corrects the distortion and has higher resolution compared with free space due to the inclusion of multipath propagation through the periodic wall, but considerable sidelobe clutter is present. The nonlinear solution not only corrects target distortion without clutter but also reduces the solution to a sparse form.

Phd thesis, Ecole nationale superieure de l'aeronautique et de l'espace, 2007. http://tel.archives-ouvertes.fr/tel-00143709.

Full text
Abstract:
L'objet de cette thèse a été de développer un code de calcul pour la simulation d'écoulements diphasiques de fluides non miscibles, incompressibles et isothermes afin de l'appliquer au phénomène de fragmentation d'un jet liquide, et plus particulièrement à la désintégration assistée d'une nappe de liquide par deux écoulements d'air portés à haute vitesse.

Les choix des hypothèses physiques et des schémas numériques associés ont été fait afin de respecter au mieux la physique complexe de brisure d'un jet liquide. La résolution des équations de Navier-Stokes incompressibles est faite de façon directe par le biais d'une méthode de projection. La méthode naissante et prometteuse Level-Set assure quant à elle le suivi numérique de la surface de séparation entre deux fluides non miscibles. Enfin, la méthode Ghost Fluid permet un traitement correct des discontinuités à la traversée de l'interface en préservant au niveau discret les conditions de saut entre équilibre des forces de capillarité, de pression et de viscosité. Les bonnes aptitudes de tels schémas numériques sont montrées à travers une batterie de cas tests académiques.

Les mécanismes physiques mis en jeu lors de l'atomisation primaire d'un jet liquide ont fait l'objet de nombreuses études théoriques et expérimentales. Les instabilités se développant à la surface du liquide sont multiples et clairement tridimensionnelles. Actuellement et malgré beaucoup d'efforts de recherche, aucune théorie ou modèle ne rend compte rigoureusement de ce phénomène. Or, il est montré que l'outil numérique peut apporter une lumière nouvelle. Par exemple, l'impact de la couche limite gazeuse sur la fréquence d'oscillation est étudié. Nous avons également pu retrouver par la simulation la dynamique ligamentaire intrinsèque à la désintégration assistée d'un jet liquide.

Abstract:
(Not) Drawing The Line: Technology Re-examined is the culmination of interdisciplinary research exploring the nature of materiality and process in the fields of art, science, and technology. Exploration and experimentation in these diverse disciplines have helped to illuminate many of the ideas and concepts that have guided the overall research process. These explorations have also honed the ability to critically examine how technology is perceived and represented, post-internet.   This document illustrates the processes involved in the conception and creation of a body of work manifested through visual and technological problem solving, investigative research of materials and technologies, and the fundamental concerns of art, technology, form and pattern. These empirical areas of research are punctuated by literary texts on the philosophy of art and technology that have informed many of the visual comparisons represented. This body of evidence is an exploration of the idea that the evolution of technological developments can often be attributed to the creation of art through the heuristic experimentation and visual explorations of the artist.

Abstract:
The creative submission for my dissertation includes two of my documentary works: They Will Take My Island, a thirty-minute multimedia collaboration with filmmaker Atom Egoyan for amplified string octet, electronic track, and film, commissioned by the Metropolitan Museum of Art; and Paper Pianos, a ninety-minute staged collaboration with director Nigel Maister and projection artist Kevork Mourad. The written submission for my dissertation is an examination of the ways in which experiences around transgenerational trauma inform and manifest in my creative practice. I offer a summary of my own family history of survivors of the Armenian Genocide and Lebanese Civil War, as well as a survey of displacement amongst the Armenian community in the past century. Furthermore, I discuss identity processing as diaspora and the act of cultural preservation, as inspired by genocide survivor, composer, priest, writer, and musicologist, Komitas Vardapet. I later examine these ideas in the context of creating They Will Take My Island and Paper Pianos, both of which were constructively motivated by transgenerational survivor’s guilt and draw from extra-musical documentary and horror genre practices.

Full text
Abstract:
This chapter revisits debates regarding the use of technology to enhance or remediate performances in the light of Emmanuel Levinas’s understanding of the ethical encounter as a face-to-face encounter between a subject and her/his other. Building on these debates and Robert Weimann’s distinction between locus and platea, it suggests that performance theory’s emphasis on the physical co-presence of spectator and performer undervalues the experience of the spectator. Using three productions that use digital media as examples, the chapter demonstrates how online live streaming (in Cheek by Jowl’s Measure for Measure), digital hologram projection (in the McGuires’ Ophelia’s Ghost), and the use of an online stage (in the RSC’s collaboration with Google+ on #dream40) each harness the affordances of digital media to create conceptual spaces in which spectators can experience ethical encounters. Digital media thus open up distinct ways of experiencing dilemmas explored by Shakespeare’s plays.

Abstract:
Accounts of the enlightened philosophical principles of Fielding’s fiction have struggled to explain the performativity of his narrator and the miraculous implausibilities of his plot. This chapter shows, however, that just as performances with spectacular machines played a key role in establishing the epistemological authority of the new science in the eighteenth century, so Fielding’s narration in Tom Jones must be seen as a constitutive element in his effort to establish the philosophical utility of the modern novel. Eighteenth-century natural philosophers performed ‘boundary-work’ that distinguished their experimental apparatus from the devices exhibited by magicians and projectors. Similarly, Fielding sought to contrast the orderly principles of his clockwork plot with the supernatural machinery of older literary forms. But natural philosophers were also sometimes accused of exploiting the popular appetite for wonder, which explains why Fielding often ironically presents himself not as a philosopher but as an unscrupulous hack or projector.

Abstract:
We will basically deal with three issues. Firstly, talking about visualization in relation to Design seems to be matter of the present era while talking about projection mostly pushes our feelings back to the past, despite even advanced digital visualizations are projection-based, or better, they are projective visualizations. Secondarily, these projective visualizations are not only mere supports to show design results but, mainly, they are irreplaceable thinking-and-operational tools for design development. Third, given their semantic wideness, these visualizations work as very customized tools in the various branches of Architectural, Engineering, or Product Design and so forth, as we also discussed in a cycle of seminars on The Visual Language of Technique Between Science and Art organized by the author during the celebrations of the 150th anniversary of Politecnico di Milano (Cocchiarella, 2015). Last, in order to connect the abovementioned issues we will remark the combined power of Geometry and Graphics, friendly called The Ghost and The Ghost-Buster and their roles over time.

Full text
Abstract:
This chapter traces the persistent association between werewolves, ghosts and the dead in the ancient world. As to werewolves proper, Herodotus’ application of the word goētes to his werewolf Neuri, in addition to saluting their ability to transmute their form, probably also implies that they engaged in ghost- or soul-manipulation. Virgil’s werewolf Moeris is a raiser of ghosts. Petronius’ werewolf story is richly decked out with the imagery of ghosts and the underworld. Marcellus of Side’s medical ‘lycanthropes’ roll around in graveyards, and indeed it would appear to be on the basis of this symptom in particular that the victims of the disease are considered to be werewolves: their projection as such is essentially metaphorical, and they should not be seen as the origin-point or the key to ancient werewolfism. Pausanias’ Hero of Temesa is a ghost or a revenant dressed in a wolfskin, whilst Philostratus’ pestilential beggar of Ephesus, revealed to be a terrible dog in his true form, is also projected as some sort of ghost or revenant.

Abstract:
This chapter analyses the singularly arresting yet endlessly repeatable appearance via projection of the iconic British supermodel Kate Moss within the recent V&A Museum exhibition Savage Beauty: Alexander McQueen. Originally created for the late fashion designer’s 2006 Widows of Culloden show in Paris, this appearance by Moss was no less rapturously received at the V&A exhibition than it had been at the hologram’s launch almost a decade previously. Drawing upon scholarship in the fields of film history and media history, the chapter argues that the Kate Moss hologram should be conceptualized not as a ‘new’ technology, but as a remediation of older cultural forms and practices such as the Victorian entertainment known as Pepper’s ghost and the genre of early cinema known as the serpentine dance. Subsequently, the chapter examines how the exhibition’s marketing and critical reception helped to construct cultures of appreciation that reinforce dominant and idealist discourses of technology. The chapter argues that contemporary film and media culture cannot be understood without an appreciation of older forms and practices of visual entertainment and amusement.

Abstract:
Chapter 3 argues that the now-canonical reading of Kate Chopin’s small masterpiece, The Awakening, which takes Edna Pontellier’s sexual wanderlust as symptomatic of a racist, primitivistic projection (per Toni Morrison’s general formulation), utterly neglects the founding plot and concerted characterizations. In The Awakening, Edna, a married Kentucky Presbyterian, is set adrift among Creole Catholics who embody a sexual sacramentality that attracts her but that she can’t, herself, achieve, beyond eventual submission to adultery with a local lothario. When the story begins, Edna is chafing in her marriage to a self-involved financier and, despite her Calvinist upbringing and persisting individualist sensibility, becomes increasingly involved, Theron-style, with a Creole trio: Madame Ratignolle, the mother-woman who is sensual in aspect and touch; Robert Lebrun, a serial acolyte of older women who refuses to deliver on his sexual promise despite beguiling her on the refulgent isle of La Chenière Caminada; and Mademoiselle Reisz, a spinster artiste, whose way with Frédéric Chopin’s nocturnes is her way with Edna, soul and (implicitly) body. Thus The Awakening is American’s first major portrayal of the Protestant-adrift-among-Catholics, and it is only as such that it becomes our proto-feminist exploration of a wife’s quest for sexual and aesthetic autonomy. Whereas Frederic’s Theron Ware is one of talkiest books ever, The Awakening delineates temptations to Catholicism that are more show then tell, capturing the fault lines of full social incorporation in Edna’s fatal sea-swim, which can be understood both as a capitulation, in resurgent Protestant self-immolation, and as a visionary sacrifice.

Abstract:
Demonstrates the importance of the magic lantern to Joyce’s ‘media-cultural imaginary’ and the cinematicity of his techniques and themes. The lantern provided a major cultural and technological context giving birth to film. Despite appearing to ‘bar’ its influence, Dubliners alludes widely to lantern motifs, genres and techniques, explaining how Joyce’s innovations appear modernistically cinematic before film developed equivalent techniques. Chapter 1 demonstrates the fundamental part lanternism played in Joyce’s ekphrastic method: in projection effects and multi-layered intrusions of images from one context into another, but also in ‘dissolving views’ transitioning in space, time and consciousness. Lanternism sheds light on Joyce’s use of ‘flashback’ form several years before film editing, because it represented ‘multi-spatiotemporality’ by superimposing or inserting images visualising thoughts or fantasies, presenting dynamic narrative transformations in photographic ‘life-model’ sets, the predecessors of film features but also a parallel influence on Joyce. The lantern also had a reputation as a ‘technology of the uncanny’, Joyce evoking its ‘phantasmagoria’ for the uncanny vision climaxing Dubliners, a verbal ‘dissolve’, in which a moving ghost world replaces mundane reality. Thus Dubliners’ cinematicity references film’s inheritance from lanternism and anticipates its narrative futures.

Full text
Abstract:
This chapter explicates holographic projections as the second instantiation of post-screen media. Often mistaken as holograms, these projections of images ranging from Tupac to Julian Assange to holographic protests redraw the boundaries between life and death, and enable a re-imagination of ghosts, deadness, aliveness and afterlife. The chapter argues for four different moments in a history of ghosts in the media: resurrection; necrophilia; necromancy; and interactivity. The last facilitates spectral life in the post-screen through considering holographic projections of both dead and living figures. In relation to the dead, the post-screen becomes a space in limbo between deadness and aliveness; in relation to the living, the realness of the holographic body stretches in a tetravalence across dual axes of actual/virtual and here/elsewhere, and enlivened in what I call vivification. In these 3D displays on the post-screen of resurrected and vivified bodies, different kinds of life, afterlife and after-death emerge.

Abstract:
This chapter discusses true holograms as a “remix” discussion from Chapter 4 of ghosts out of the post-screen. Commonly confused with holographic projections, true holograms are two-dimensional images naturally viewed (i.e. without optical aids) as 3-dimensional objects. Leveraging theoretical sources such as Deleuze’s notion of “the brain is the screen” and Vilém Flusser’s ideas of point culture and linearity, the chapter argues for the post-screen through the true hologram whose ghosts are not of the spectral return of the dead, but digital apparitions via which the human mind ideates and projects realities. These digital ghosts thus return with a necromancy of their own on the terms of zerodimensionality and post-rationality, confronting us with new problems of reality and questions about ourselves.

DNS simulations are carried out to obtain information in the dense zone of a spray where nearly no experimental data are available. Interface tracking is ensured by Level Set method, Ghost Fluid Method (GFM) is used to capture accurately sharp discontinuities for pressure, density and viscosity. Coupling between Level Set and VOF method is used for mass conservation. Fluid motion is predicted with a projection method for incompressible flows. The numerical methods are described and validations are presented. First results are then presented for 3D simulation of the primary break-up of a liquid jet with the Level Set-VOF-Ghost Fluid method and the results can help to determine closure relation in the ELSA model [Part II of the paper] which is based on a single-phase Eulerian model and on the transport equation for the mean liquid/gas interface density in turbulent flows.

Abstract:
We are here concerned by the primary break-up of a jet: a lot of topological changes occur and the Level Set Method thus appears well designed for our purpose. To describe the interface discontinuities, we use the Ghost Fluid Method (GFM) and a projection method is used to solve incompressible Navier-Stokes equations that are coupled to a transport equation for the level set function. The main drawback of level set methods is that numerical computations in the re-distancing algorithm can generate mass loss in under-resolved regions. To improve mass conservation extension of the method can be developed, namely a coupling between VOF and Level Set. In order to illustrate the abilities of the Level Set/VOF/Ghost Fluid method for interface tracking, we present a 3D simulation of the primary atomization zone of a turbulent liquid jet. The turbulence initiates some perturbations on the liquid surface, that are enhanced by the mean shear and break-up occurs. The generated liquid parcels show a wide range of shapes. Particular behaviors such ligament detachments, droplet formations and break up are described.

Abstract:
This paper investigates the dynamics of a slender beam subjected to transverse periodic excitation. Of particular interest is the formulation of nondegenerate continuation problems that may be analyzed numerically, in order to explore the parameter-dependence of the steady-state excitation response, while accounting for geometric nonlinearities. Several candidate formulations are presented, including finite-difference (FD) and finite-element (FE) discretizations of the governing scalar, integro-partial differential boundary-value problem (BVP), as well as of a corresponding first-order-in-space, mixed formulation. As an example, a periodic BVP — obtained from a Galerkin-type, FE discretization with continuously differentiable, piecewise-polynomial trial and test functions, and an elimination of Lagrange multipliers associated with spatial boundary conditions — is analyzed to determine the beam response via numerical continuation using a MATLAB-based software suite. In the case of an FE discretization of the mixed formulation with continuous, piecewise-polynomial trial and test functions, it is shown that the choice of spatial boundary conditions may render the resultant index-1, differential-algebraic BVP equivariant under a symmetry group of state-space translations. The paper demonstrates several methods for breaking the equivariance in order to obtain a nondegenerate continuation problem, including a projection onto a symmetry-reduced state space or the introduction of an artificial continuation parameter. As is further demonstrated, an orthogonal collocation discretization in time of the BVP gives rise to ghost solutions, corresponding to arbitrary drift in the algebraic variables. This singularity is resolved by using an asymmetric discretization in time.

Abstract:
A projection approach is presented for the coupled system of time-dependent incompressible Navier-Stokes equations in conjunction with the Immersed Boundary Method (IBM) for solving fluid flow problems in the presence of rigid objects not represented by the underlying mesh. The IBM allows solving the flow for geometries with complex objects without the need of generating a body fitted mesh. The no-slip boundary constraint is satisfied applying a boundary force at the immersed body surface. Using projection and interpolation operators from the fluid volume mesh to the solid surface mesh (i.e., the “immersed” boundary) and vice versa, it is possible to impose the extra constraint to the incompressible Navier-Stokes equations as a Lagrange multiplier in a fashion very similar to the effect pressure has on the momentum equations to satisfy the divergence-free constraint. The projection operation removes the immersed boundary surface slip and non-divergence-free components of the velocity field. The boundary force is determined implicitly at the inner iterations of the fractional step method implemented. No constitutive relations for the immersed boundary objects fluid interaction are required, allowing the formulation introduced to use larger CFL numbers compared to previous methodologies. An overview of the immersed boundary approach is presented showing third order accuracy in space and second order accuracy in time when the simulation results for the Taylor-Green decaying vortex are compared to the analytical solution using the Immersed Finite Element Method (IFEM). For the Immersed Finite Volume Method (IFVM) a ghost-cell approach is used. Second order accuracy in space and first order accuracy in time are obtained when the Taylor-Green decaying vortex test case is compared to the analytical solution. The numerical results are compared with the analytical solution also for adaptive mesh refinement (for the IFEM) showing an excellent error reduction. Computations were performed using IFEM and IFVM approaches for the time-dependent incompressible Navier-Stokes equations in a two-dimensional flow past a stationary circular cylinder at Re = 20, and 40, where shedding effects are not present. The drag coefficient and the recirculation length error compared to the experimental data is less than 3–4%. Simulations for the two-dimensional flow past a stationary circular cylinder at Re = 100 were also performed. For Re numbers above 46, unsteadiness generates vortex shedding, and an unsteady flow regime is present. The results shown are in excellent quantitative and qualitative agreement with the flow pattern expected. The numerical results obtained with the discussed IFEM and IFVM were also compared against other immersed boundary methodologies available in literature and simulation performed with the commercial computational fluid dynamics code STAR-CCM+/V5.02.009 for which a body fitted finite volume numerical discretization was used. The benchmark showed that the numerical results obtained with the implemented immersed boundary methods are very close to those obtained from STAR-CCM+ with a very fine mesh and in a good agreement with the other IBM techniques. The IBM based of finite element approach is numerically more accurate than the IBM based on finite volume discretization. In contrast, the latter is computationally more efficient than the former.

Abstract:
For the stability of offshore structures, such as offshore wind foundations, extreme wave conditions need to be taken into account. Waves from extreme events can become critical from design perspective. In a numerical wave tank, extreme waves can be generated through focussed waves. Here, linear waves are generated from a wave spectrum. The wave crests of the generated waves coincide at a pre-selected location and time. In order to test the generated waves, the time series of the free surface elevation are compared with experimental benchmark cases. The numerically simulated free surface shows good agreement with the measurements from experiments. In further computations, the wave impact of the focussed waves on a vertical circular cylinder is investigated. The focussed wave generation is implemented in the numerical wave tank module of REEF3D, which has been extensively and successfully tested for various wave hydrodynamics and wave-structure interaction problems in particular and for free surface flows in general. The open-source CFD code REEF3D solves the three-dimensional Navier-Stokes equations on a staggered Cartesian grid. Solid boundaries are taken into account with the ghost cell immersed boundary method. For the discretization of the convection terms of the momentum equations, the conservative finite difference version of the fifth-order WENO (weighted essentially non-oscillatory) scheme is used. For temporal treatment, the third-order TVD (total variation diminishing) Runge-Kutta scheme is employed. For the pressure, the projection method is used. The free surface flow is solved as two-phase fluid system. For the interface capturing, the level set method is selected. The level set function can be discretized with high-order differencing schemes. This makes it the appropriate solution for wave propagation problems based on Navier-Stokes solvers, which requires high-order numerical methods to avoid artificial wave damping. The numerical model is fully parallelized based on the domain decomposition, using MPI (message passing interface) for internode communication.

Abstract:
Analysis of the interior ballistics is essential for the development of gun or propellant configurations. The granular solid propellants with high energy and fast burning rate produce a large thrust in extremely short time intervals. For the study of these, therefore, it is necessary of a numerical code for the two-phase flow of the interior ballistics. Recently, an interior ballistics code (IBcode) for the two-phase flow using the Eulerian-Lagrangian approach has been developed. The SIMPLE algorithm and the SMART scheme have been used for the IBcode. The ghost-cell extrapolation method has been used for the moving boundary with the projectile movement. In this study, a performance of the interior ballistics according to the position of the solid propellant in the chamber has been investigated using the IBcode. In previous researches, propellants had been evenly distributed in the chamber. In this study, however, three cases of the existence of empty space in the chamber at which the propellants are not evenly distributed have been considered; Propellants are located in the region near the base, propellants in the region near the breech, and propellants in the center of the chamber, respectively. The 7-perforated configuration of the solid propellant has been used in this research. The results have shown the performance variations of the interior ballistics according to solid propellant position in the chamber. The cases of the propellants located in the region near the base and breech have shown that the value of the negative differential pressure and the difference between the breech pressure and the base pressure are much higher than those of the propellants located in the center of the chamber. The case of the propellants in the center of the chamber is, therefore, more profitable to improve the performance of the interior ballistics.
