Thesis (M.C.P.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning; and, (M.Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 1995.Includes bibliographical references (p. 143-146).
In this thesis I strive to explore the question, "what is good architecture?" through the design of a facility for formal and informal musical and theatrical performance. The site for this project is in Central Square, Cambridge, Massachusetts, on the Southeast comer of Massachusetts Avenue and Prospect Street. The program of the design includes a multi-use theater supported by first and second level commercial retail space, a multi-floored office space, and integrated subway station, each included to encourage pedestrian traffic and generate revenue. Additionally, the facility includes a jazz club, a folk room, and a rock club. The final product is a hybrid of existing facilities and ideas developed with prospective facility users; I have made efforts to take advantage of the knowledge and ideas of some users in determining the program and design. The facility aims to encourage and facilitate community integration with use-specific and non-use specific elements. It aims to strengthen the pattern of public gathering now inhibited by the spatial arrangement of the area. Among the important areas of inquiry, I focus considerable attention on the outdoor and semi-outdoor public space of the facility. The design intends to generate an eddying effect on the linear flow of pedestrian traffic down Massachusetts Avenue. By providing areas for street performers with sheltered seating and standing areas for itinerant audiences, this space intends to take on a theatric and communal character. To achieve the goals set out above I have drawn upon a process involving design, theory, and precedent models falling under three main categories. Design Precedents: -Theaters; -Music Halls; -Night Clubs. Organizational Design Precedents: -User Involved Design Tools; -User Involved Design Precedents. Inventive Programming Precedents: -Personal Account of Inventive Process; -Case investigation.

Full textAbstract:
Young characters throughout the history of Australian theatre have traditionally been represented as tragic, transient, and dangerous; discourses which have defined and limited their construction. 'Youth' itself is a concept which has been invented and perpetuated within Western Art and Media for much of the twentieth century and beyond, creating an exclusive 'space' for young people: a space between childhood and a standard human being. This thesis seeks to explore the implications of this space, as well as contextualise a new creative work - the stage play like, dead - within the canon of Australian theatre texts which portray young characters. like, dead will be shown to be a work which reappropriates clichéd youthful discourses through the use of irony, humour, and a sense of postmodern 'performativity' among its characters. In so doing it will demonstrate an alternative approach to representing young people on the Australian stage, by enhancing the constructedness of traditional images of 'youth' and pursuing the creation of young characters which are not solely defined by the term.

Full textAbstract:
EnglishPh.D.
My dissertation examines how early modern metatheater enabled the Renaissance stage and its original audience to develop a complex and symbiotic relationship. Metatheater--by which I mean a particular mode of theatre, in which actors, playwrights, dramatic characters and/or (in particular) audiences express or share a perception of drama as a fictional and theatrical construct--pervaded Renaissance drama, not by simple happenstance but arising almost inevitably from the complex context within which it functioned. The early modern stage was a particularly conflicted forum, which monarchs and playwrights, town fathers and actors, censors and audiences, impresarios and anti-theatricalists, all strove to influence and control. The use of the metatheatrical mode allowed playwrights and players to better navigate this difficult, sometimes dangerous, space. In particular, the development of Renaissance metatheater derived from (and, simultaneously, affected) the unique nature of its original spectators, who practiced a much more actively engaged participation in the theater than is often recognized. Performers and playwrights regularly used metatheatricality to adapt to the needs and desires of their audience, and to elicit the intellectual and emotional responses they desired. My study utilizes a historically contextualized approach that emphasizes the material conditions under which Renaissance drama arose and functioned. It begins by examining the influence of the surrounding milieu on the Renaissance stage and its spectators, especially its facilitation of the development and use of metatheater. Then, via close readings of four plays--Kyd's The Spanish Tragedy, Shakespeare's Henry V and Antony and Cleopatra, and Beaumont's The Knight of the Burning Pestle--the dissertation indicates how varied and versatile early modern metatheater was, and how it responded to and influenced the nature of its audiences. My study demonstrates the centrality of metatheater to early modern theatrical practice, delineates its pervasive influence on the stage-audience relationship in Renaissance theaters, and underlines the influence of material conditions on the creation and dissemination of Elizabethan and Jacobean drama.

Full textAbstract:
With the developments in space technology, the capabilities of spacecrafts have been
increased considerably which in turn have entailed the development of more efficient
spacecrafts in terms of cost, mass, size and power. One way to achieve such a development
is the replacement of body mounted appendages with the deployable ones, which greatly
reduces the size, mass and cost of the spacecraft especially when large appendages are
considered. In order to obtain these deployable structures, deployment mechanisms and
deployment mechanism drivers are used. A deployment mechanism is a combination of
electrical and/or mechanical structures which hold the appendages in the stowed position
before launch and deploys them after the launch with the power and commands supplied by
the deployment mechanism driver. This necessary power of the deployment mechanism
driver is produced by the Power Stage of the deployment mechanism driver and the
necessary commands required by the deployment mechanism are supplied by the Control
Stage of the deployment mechanism driver. In this thesis, the power stage of a deployment
mechanism driver will be designed and implemented taking into account of the
requirements for Low Earth Orbit Satellites such as temperature tolerance, reliability and
radiation limits. In order to acquire a cost, mass and size efficient Power Stage, different
deployment mechanism topologies will be studied and the most convenient one among
these topologies will be chosen as the deployment mechanism driver load and the design
will be performed accordingly.

Temizer, Seda. "Reading Architectural Space Through A Staged Event." Master's thesis, METU, 2004. http://etd.lib.metu.edu.tr/upload/3/1218379/index.pdf.
Full textAbstract:
This study is an inquiry into the architectural aspects of stage space, which is believed to be the materialization of visual relationships, with the claim that it is also the best illustration of the proposition that architectural discourse is affected by the changes in visual culture. The study is based on the assumption that changes in the conceptualization of architectural space have also been influenced from the shifts in the field of vision, which are the consequences of the changes in the social, political and economical circumstances as well as the developments in science and technology.
Within the acknowledgement of three major shifts in the field of vision that have been identified by Jonathan Crary, the study focuses on a reading and assessment of twentieth century developments that differ from the traditional conception of space and ways of spatial representation. Being a key to reconsider architectural space production, the outcomes of these developments are read through the construction of stage and performance spaces.
Stage space possesses knowledge about the making of
architecture. This study is an attempt to demonstrate how stage space is in relation to or anticipates changes in conception of architecture. Because of its instant nature and flexibility, stage space can be seen as a tool for making experiments for possible changes in the conception of architectural space.

Full textAbstract:
Variable speed drive technology has advanced dramatically in the last 10 years with the advent of new power devices. In this study, a three phase induction motor drive using Insulated Gate Bipolar Transistors (IGBT) at the inverter power stage is introduced to implement speed and position control for the revolving stage in the Frederic Wood Theatre
This thesis presents a solution to control a 3-phase induction motor using the Texas Instruments (TI) Digital Signal Processor (DSP) TMS320F2407A. The use of this DSP yields enhanced operations, fewer system components, lower system cost and increased efficiency. The control algorithm is based on the constant volts-per-hertz principle because the exact speed control is not needed. Reflective object sensors which are mounted on concrete frame are used to detect accurate edge position of revolving stage. The sinusoidal voltage waveforms are generated by the DSP using the space vector modulation technique.
In order to satisfy some operating conditions for safe and agreeable operation, a look-up table, which is used to give command voltage and speed signals in software, is applied to limit the maximum speed and acceleration of the revolving stage. Meanwhile, a boost voltage signal is added at the low frequency areas to make the motor produce maximum output torque when starting.
A test prototype is then built to validate the performance. Several tests are implemented into the IGBT drive to explore the reason for unacceptable oscillations in IGBT’s gate control signals. Improvement methods in hardware layout are suggested for the final design.

Full textAbstract:
The effects of impeller-diffuser interaction are investigated through numerically simulating the modified wedge vane profiles. Steady and time-accurate, 3D- viscous RANSsolver is used to perform flow field computations. The original design is modified to obtain better aerodynamic performance. Five morechanges are made to the leading edge profile of the new design, in order to assess different degrees of unsteadiness. These changes show that their contribution on stageefficiency is rather minor, while they have a huge reduction on blade loadings. Moreover, it is shown that the shorter radial distance of vaneless space does not necessarilymean an increased loading thanks to the eliminating in-phase fluctuations on pressureand suction sides. It is found that the impeller reacts to the upstream static pressure disturbance, whichis caused by the applied geometry change and its resultant flow field in the wedge diffuser, but not to the radial location of a certain profile. In addition, the results indicatethat the wedge diffuser aerodynamic performance is driven by time-averaged flow fieldbehaviour.

Full textAbstract:
This project examines representations of Antarctica in the theatre and analyses these in terms of space and place in order to chart the development of awareness of the continent. As examples of cultural production, plays and their treatment of imagined Antarctic space can provide insights into how attitudes towards the continent have developed and been expressed by revealing the dominant narratives at various points in time. A close reading of nine plays from 1930 – 2011 focuses on the use of mimetic and diegetic space within the theatre, examining the language used, stories told and attitudes present. Such analysis reveals the factors determining the choice of an Antarctic setting, be they ecological, political or metaphorical, whilst shedding light on how attitudes towards place, space and representation have changed within the theatre context.
These plays can be grouped under four thematic headings, namely “In Scott’s Footsteps,” “Retelling,” “Reimagining,” and “Returning.” While Antarctica remains a backdrop in earlier plays, where Heroic Era narratives are foregrounded, more recent productions have seen the continent come to the fore, where it is treated as part of a global web of connections. These plays illustrate a progression in how Antarctica has been represented upon the stage, a progression that parallels how we have thought about Antarctica in general.

Full textAbstract:
Theatre is a location of cultures, the reflection of our daily lives, the present moment we are living. This thesis focuses on studying performances of the Hakka Contemporary Theatre created by female directors (Hakka and Non-Hakka) in Taiwan to observe how they combine western modern theatre forms with Hakka traditional and cultural elements and further transformed the specifics of Hakka culture on stage and represented various images of Hakka women. Through applying theories in relation to diaspora discourse, the hybridity of post-colonialism and postcolonial feminism and theatre study as the foundation of academic research, I attempted to critically examine the hybrid forms and development of the Hakka Contemporary Theatre to explore in depth the meaning of Hakka culture represented in theatre. In this thesis, I firstly offer performance analysis and draw on hybridity discourse and feminism in relation to post-colonial study to discuss three elements: the interaction and negotiated relationship between Hakka women (including female directors and the Hakka actresses), Hakka culture, and modern theatre forms. Furthermore, as part of my research, I critically reflect upon a practical performance project I have undertaken to illustrate how Hakka culture could be presented as subject and be constructed as the subjectivity of the Hakka ethnic group in post-colonial Taiwan. I hope that this thesis may encourage more Taiwanese to appreciate the value of Hakka culture and offer Taiwanese theatrical practitioners a practice of critical hybridity in associating ethnic and cultural issues of Taiwan in the future.

Full textAbstract:
Through his use of "foundation" and "house" metaphors in his "First Sermon Preached to King Charles at St. James, 3 April 1625," John Donne discreetly presents his ideologies and principles before the new king, while simultaneously criticizing his contemporaries' misguided bickering over religio-political factions. This essay seeks to unpack the history surrounding, as well as the casuistical logic found within Donne's first sermon preached during the Caroline period, which both explicitly and implicitly addresses the foremost anxieties of the people of the changing age.

Full textAbstract:
Doctor of PhilosophyThis thesis presents a systematic investigation of the backstage spaces of theatres in the city of Sydney, Australia, combining the documentation of eight specific theatre buildings with ethnographic accounts of performers’ activities within them. As the title of the thesis suggests, my focus throughout is to better understand the ‘place’ of performers, the ways in which performers inhabit certain physical, social, and imaginative realms. Through this thesis I assess the impact of backstage spaces on performers’ work processes, their performances, and their own understandings of what it is to be a performer. To undertake this assessment I conduct a tripartite survey of the backstage spaces afforded performers, taking into consideration ‘perceived’ space (space as it is empirically measured), ‘conceived’ space (space as it is represented), and ‘lived’ space (space as it is experienced). Approaching this survey via Edward Casey’s understanding of ‘place,’ my analysis is informed by a range of theories, notably, spatial syntax analysis, discourse analysis, and phenomenology. Through this thesis I develop two overarching and interconnected arguments. The first is that theatrical performance is profoundly affected by the features of backstage support spaces and by performers’ backstage practices. Building on this, the second is that a study of backstage spaces offers a particularly apposite approach to further understanding the ‘place’ of theatrical performers. I contend that the backstage spaces performers inhabit can be characterised by their very poverty and that these poor conditions testify to a widespread ignorance and ambivalence on the part of society at large towards performers’ needs. Furthermore, noting the way in which performers valorise their own abilities to compromise and adapt, I argue that backstage areas largely inform performers’ dominant discourses of professionalism and worth. Ultimately, I identify the ‘place’ of the performer as one of flux that necessitates the constant negotiation of significant tensions.

Os conceitos de belo e sublime em Schiller, apoiados numa estética kantiana, conduziram a filosofia para uma possibilidade de educação estética do homem, responsável pela plena liberdade e realização da vontade humanas. Dentro desse panorama, disposto a traçar um caminho de representação na arte dessa liberdade humana, Schiller propõe o conceito de tragédia moderna. Sobre seus fundamentos e sobre o seu propósito de repensar a poética da tragédia se debruçará essa dissertação. Em que medida a tragédia schilleriana é, de fato, capaz de definir o trágico e libertar o homem?
Johann Christoph Friedrich von Schiller s conceptions of the beautiful and the sublime - unquestionably influenced by Kantian Aesthetics - have conducted Philosophy to a possibility of aesthetic formation/education of individuals. This possibility has endowed them to attain complete autonomy in regards to their exercise of freedom and free will. It is within this context that Schiller, determined to represent this newfound notion of human autonomy in art, fosters his notion of modern tragedy. It is the purpose of this dissertation to study and scrutinize Schiller s groundings and intent to transform the notion of tragedy. The present investigation shall attempt to answer such questions as till what point is Schillerean tragedy indeed able to define the concept of -the tragic-, and render individuals free?

Full textAbstract:
Inverters play key roles in connecting sustainable energy (SE) sources to the local loads and the ac grid. Although there has been a rapid expansion in the use of renewable sources in recent years, fundamental research, on the design of inverters that are specialized for use in these systems, is still needed. Recent advances in power electronics have led to proposing new topologies and switching patterns for single-stage power conversion, which are appropriate for SE sources and energy storage devices. The current source inverter (CSI) topology, along with a newly proposed switching pattern, is capable of converting the low dc voltage to the line ac in only one stage. Simple implementation and high reliability, together with the potential advantages of higher efficiency and lower cost, turns the so-called, single-stage boost inverter (SSBI), into a viable competitor to the existing SE-based power conversion technologies.
The dynamic model is one of the most essential requirements for performance analysis and control design of any engineering system. Thus, in order to have satisfactory operation, it is necessary to derive a dynamic model for the SSBI system. However, because of the switching behavior and nonlinear elements involved, analysis of the SSBI is a complicated task.
This research applies the state-space averaging technique to the SSBI to develop the state-space-averaged model of the SSBI under stand-alone and grid-connected modes of operation. Then, a small-signal model is derived by means of the perturbation and linearization method. An experimental hardware set-up, including a laboratory-scaled prototype SSBI, is built and the validity of the obtained models is verified through simulation and experiments. Finally, an eigenvalue sensitivity analysis is performed to investigate the stability and dynamic behavior of the SSBI system over a typical range of operation.

Thesis (M. Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 1996.Includes bibliographical references (p. 87-88).
People of all races, cultures and religious backgrounds share the need for public places which allow for human interaction and self expression. Unfortunately, in Istanbul, a city of twelve million people where public space has historically been associated with the mosque, historical precedents for secular public places such as this do not exist. Since the decline of the role of religion in social and governmental settings, the mosque courtyard has become primarily a place for ablution, and has lost its quality for gatherings. Yet, today, the city fabric has not changed to accommodate for the space which the mosques provided long ago. As a result, there is a great need for the improvement of public space, and for the making of new public gathering places in Istanbul. This thesis explores the introduction of a public open space into one of the unused sections of the waterfront in Istanbul, and the site for this project is that of the old loading docks and warehouses located across from the Tophane Museum--the historic Ottoman Artillery. The proposed plaza is located at a crossing of many transportational and recreational paths accentuated by the design. As a result the place becomes a nodal point. Self expression and play are the guiding forces behind the program which revolves around a big pool, full of activities, which recognizes water as the life giver to the city of Istanbul.

Studham, Susan Fenty. "Stage management: A question of approach in intercultural theatre." Thesis, Edith Cowan University, Research Online, Perth, Western Australia, 2015. https://ro.ecu.edu.au/theses/1588.
Full textAbstract:
This thesis questions the complexities of stage management in crosscultural exchanges by way of a case study surrounding the mounting and maintenance of an original theatrical production in Bali, utilising an introduced western theatre style. The collaboration takes place in the newly constructed mega-theatre at the Bali Safari and Marine Park in Gianyar (2010). As an American-Australian stage manager, my research is predicated on experiences of leading and mentoring a team of ten Indonesian (Balinese and Javanese) stage managers in procedures required to manage a technically-advanced, large-scale production. Bali Agung presents a legend of Balinese goddesses in a production that was created by an international artistic team featuring a cast of more than 150 Balinese performers, plus 11 species of animals and supported by a technical team of approximately 70. Due to the inexperience of the team, formal training became an aspect of the exchange. During the research process, I returned to Bali numerous times for data collection, further mentoring, rehearsals and productions at Bali Theatre, thus couching the investigation in an ethnographic study and an integral action research feedback loop.
The investigative focus is on the production requirements of a mega show in an intercultural context and the unique and extraordinary considerations that were encountered in the process. Considerations include theoretical concepts such as syncretism, interculturalism, hybridity, time, communication, safety management and religion, all of which have bearings on this case study. Re-evaluation of the production processes by means of interviews, observation, action research and ethnography offers the opportunity to shed new light on approaches to stage management and the training of stage managers in an intercultural context. Framed by a professional theatrical production, this practice-led study explores ideas of synthesis, cultural variation, knowledge transfer and assumptions embedded in theatrical processes, and brings into focus previously undocumented creative negotiations and complexities of exchange, which offer new concepts in the discipline of stage management.

Full textAbstract:
During the interwar period in Iran and Egypt, local and regional manifestation of tajadod/al-jidida (modernity) as a “cultural identity crisis” created the nationalist image and practice of zan-e emrouzi-e shahri/al-mar’a al-jidida al-madani (the urban/secular “New Woman”). The dynamics of the process involved performance art, including the covert medium of journalism and the overt world of the performing arts of music, play, and cinema. The image of the “New Woman” as asl/al-asala (cultural authenticity) connected sonnat/al-sunna (tradition) with the global trends of modernism, linking pre-nineteenth century popular forms of performing arts to new genres, forms, and social experiences of the space of the performing arts. The subversive transnational character of performance art operated across borders to promote both the discourse of modern womanhood in-the-making among intellectuals, and the public practice of women’s presence among the masses. However, the trans-border effects of the medium were limited by local cultural and political ideologies of nationalism. The spectacle of women on the screen addressed national independence and the creation of a national film industry to resist the financial dominance of Europeans. In Iran, zan-e emrouzi-e shahri served the project of founding a modern nation-state, elevating of a culture of the city and urban development, and institutionalizing performing arts, mirroring the upholding of “male-guardianship.” In Egypt, in the absence of an authoritarian modern state and long-term experience of foreign occupations, al-mar’a al-jidida al-madani accompanied the traditional figure of bint al-balad (the countryside girl) to present modern advancements in film production with a traditional accent, to oppose European cultural values, to provide a tangible space for women’s multifaceted anti-colonial maneuvering, and to connect Egypt’s past history to its future. Performance art helped women to convey their cultural nationalism and a sense of imagined identity by letting them see and be seen by each other, create interactions between the artist and the audience, and emphasize music as the heart of a society’s culture and art. A culture of body performance, a female visual public sphere, and a feminine (and feminist) interpretation of cultural authenticity in performance art led women to claim the profession as a legitimate career.

Full textAbstract:
Space-time Adaptive Processing (STAP) is a two-dimensional filtering technique for antenna array with multiple spatial channels. The name "space-time" describes the coupling of these spatial channels with pulse-Doppler waveforms. Applications for STAP includes ground moving target indicator (GMTI) for airborne radar systems.
Today, there are strong interests to develop STAP algorithms for operations in “sample starved” environments, where intense environmental interference can reduce STAP capacity to detect and track ground targets. Careful applications of STAP can effectively overcome these conditions by suppressing these interferences and maximize the signal to interference plus noise ratio (SINR). The Multi-stage Wiener filter (MWF) and principal component signal dependent (PC-SD) algorithm are two such methods that can suppress these interference through truncation of the signal subspace.
This thesis makes contribution in several ways. First it details the importance of rank compression and sample compression for effective STAP operations in “sample starved” environments. Second, it shows how MWF and PC-SD could operate in this type of environment. Third it details how a “soft stop” technique like diagonal loading (DL) could improve STAP performance in target detection for MWF and PC-SD. Fourth, this thesis contrasts the performance of several existing “hard stop” techniques in rank compression and introduces a new one using a-priori knowledge.

Full textAbstract:
A compact air separator demonstrator based on centrifugally enhanced distillation has been studied. The full size device is meant to be used on board of a Two Stage To Orbit vehicle launcher. The air separation system must be able to extract oxygen in highly concentrated liquid form (LEA, Liquid Enriched Air) from atmospheric air. The LEA is stored before being used in a subsequent rocket propulsion phase by the second stage of the launcher. Two reference vehicles are defined, one with a subsonic first stage and one with a supersonic first stage. In both cases, oxygen collection is performed during a cruise phase (M 0.7 and M 2.5 respectively). The aim of the project is to demonstrate the feasibility of the air separation system, investigate the separation cycle design, and assess that the separator design selected is suitable for the reference vehicles.The project is described from original base ideas to design, construction, extended testing and analysis of experimental results. Preliminary computations for a realistic layout have been performed and the motivations for the choices made during the process are explained. Test rig design, separator design and technical discussion are provided for a subscale pilot unit. Mass transport parameters and flooding limits have been estimated and experimentally measured. Performance has been assessed and shown to be sufficient for the reference Two Stage To Orbit vehicles. The technology developed is found suitable without further optimization, although some volume and mass reduction would be desirable for the supersonic first stage concept. There are many ways of optimisation that can be further investigated. The aim of this program, however, is not to fully optimize the device, but to demonstrate that a device based on a simple, robust, low-risk design is already suitable for the launch vehicles. On top of that analysis, directions for improvements are suggested and their potentials estimated. A complete assessment of those improvements requires further maturation of the technological concept through further testing and practical implementations.
Directions for future work, general conclusions and a vehicle development roadmap have also been provided.

International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, CaliforniaA real-time telemetry simulator of the IUS spacecraft has recently entered operation to train Flight Control Teams for the 1aunch of the AXAF telescope from the Shuttle. The simulator has proven to be a successful higher fidelity implementation of its predecessor, while affirming the rapid development methodology used in its design. Although composed of COTS hardware and software, the system simulates the full breadth of the mission: Launch, Pre-Deployment-Checkout, Burn Sequence, and AXAF/IUS separation. Realism is increased through patching the system into the operations facility to simulate IUS telemetry, Shuttle telemetry, and the Tracking Station link (commands and status message).

Full textAbstract:
This study provides an examination and application of heterotopic dérive, a concept that combines spatial theories originated by Foucault and psychogeographical methods advocated by the Situationists, as enacted within theatrical performance spaces. The first chapter reviews theories related to space, place, and heterotopias, as well as the psychogeographical methods of the Situationists, particularly the dérive. The literature review is augmented with accounts of my experiences of serendipitous heterotopic dérive over a period of several years as a cast member in, or a technical director for, theatrical productions in the Department of Communication Studies Black Box Theatre. Based on the review, I postulate that heterotopic dérive is a potentially valuable phenomenon that performance studies scholar/artists can utilize consciously in the rehearsal process for mounting theatrical performances. To test this proposition, I worked collaboratively with a theatrical cast to craft a devised performance, Desire Lines, with a conscious effort to engender heterotopic dérive in the process of creating the performance. This performance served as the basis for the second chapter of the study, which analyzes and discusses of the results of that investigation. This project enhances understanding of the significance of the places and spaces in which performers practice their craft, and argues for the potential of recognizing and utilizing the agency of heterotopic spaces such as the Black Box.

Full textAbstract:
Cette étude s’intéresse à l’espace mental comme nouveau terrain d’exploration du drame britannique contemporain, et examine les manifestations d’un mouvement qui « met en pièces » les régions inexplorées des pensées inconscientes et les contrées impénétrables du traumatisme. Puisant dans les découvertes de la psychanalyse et des sciences cognitives, inspiré par le changement de paradigme de la mécanique quantique et ses interrogations sur le rôle et la nature de la conscience, ce théâtre non plus tant « in-yer-face » que « in-yer-head » s’éloigne de la sensibilité des années 1990. Les pièces de Crimp, Kane, Churchill, Cooper, Frayn, Stephens, Payne, Haddon, Ravenhill, Neilson et d’autres déconstruisent et reconstruisent le personnage comme la somme virtuelle de tous ses possibles. Le mode d’existence spéculatif, diffracté et pluriel du sujet renouvelle les définitions du réalisme psychologique et du réalisme théâtral. Ce travail étudie les modalités de cette « psychopoétique quantique » autour de concepts clés comme la probabilité ou l’incertitude, et montre comment des métaphores issues de la théorie quantique comme la dualité onde-particule ou les mondes multiples servent à illustrer l’indétermination de la psyché en évoquant les mécanismes de défense et autres symptômes qui constituent la réalité subjective d’esprits affectés par le traumatisme, la psychose, le stress ou la maladie neurologique. Nous montrons qu’en explorant la nature de la conscience, du soi et de la réalité ainsi que la condition des femmes, ces pièces posent des questions philosophiques sur le libre arbitre et la possibilité de choix dans un monde devenu plus incertain et imprévisible que jamaisThis study asserts that the human mind has become the new frontier in contemporary British drama, and interrogates and assesses manifestations of this movement which stages uncharted regions of thought and the dark territories of traumatic mindscapes. Drawing on theories from psychoanalysis and cognitive science, and inspired by the paradigm shifts of quantum mechanics and its interrogations on the role and nature of consciousness, this new theatre moves from “in-yer-face” to “in-yer-head” and away from the sensibility of the “nasty nineties.” Plays by Crimp, Kane, Churchill, Cooper, Frayn, Stephens, Payne, Haddon and others deconstruct and reconstruct the character as thevirtual sum of all her possibilities. In these mental spaces, the subject’s speculative, diffracted and plural mode of existence redefines psychological realism and stage realism. Examining the modalities of a quantum “psychopoetics” around key concepts such as probability and uncertainty, I show how metaphors borrowed from quantum theory based on the double slit-experiment, the wave-particle duality, the wavefunction collapse, the observer effect, quantum decoherence, quantum entanglement, and the many-worlds interpretation are used to emphasise the intrinsic indeterminacy of our minds. They evoke a number of psychological defense mechanisms and other symptoms that constitute the subjective reality of disturbed minds affected by trauma, psychosis, stress or neurological disease. By exploring the nature of mind, the self, and reality, and the condition of women, these plays address philosophical questions about free will and choice in a world that has become more uncertain and unpredictable than ever

Full textAbstract:
Si le mot « hors-scène » est utilisé de manière empirique pour désigner des espaces, des personnages ou des épisodes invisibles, il n’appartient pas au vocabulaire technique du théâtre et il est parfois remplacé, dans l’usage, par des mots empruntés à d’autres champs artistiques comme « hors-champ », « off » ou « hors-cadre ». Ce flou terminologique en fait une notion-miroir reflétant des positionnements esthétiques et idéologiques, qui peuvent se rattacher à un discours de valorisation de l’invisible par opposition à une société de l’image. On l’abordera à travers l’œuvre de trois auteurs majeurs de la seconde moitié du XXe siècle, Marguerite Duras, Bernard-Marie Koltès et Jean-Luc Lagarce. Ils brouillent en effet, selon des modalités différentes, l’articulation de la scène et du hors-scène, donnant lieu, de ce fait, à des mises en scène et à des scénographies qui doivent se confronter à la redéfinition des limites de l’espace de la représentation. La frontière entre le visible et l’invisible ne coïncide plus chez eux avec l’articulation entre la scène et un espace périphérique contigu : elle est mobile et ne se laisse pas aisément localiser, et le hors-scène ne peut plus être envisagé comme un extérieur. Il peut être situé au cœur du visible ; il peut être issu d’un geste de cadrage qui organise les relations de la scène, de la salle et du monde, mais aussi d’un geste de montage qui en fait un hors-temps. Il se manifeste donc de manière discontinue, à travers des brèches ouvertes par divers moyens à l’intérieur d’un espace dramatique et/ou scénique aux limites fluctuantes. C’est pourquoi cette recherche se propose de dégager les enjeux dramaturgiques et scénographiques des usages du hors-scène dans les textes de ces auteurs, mais aussi dans une sélection de mises en scène de la seconde moitié du XXe siècle et du début du XXIe siècle ainsi que de scénographies, et de certaines créations sonores qui y sont associées. Il s’agit ainsi d’identifier différentes catégories de hors-scène et de définir plus précisément une notion qui pourrait bien manifester une modification des modalités de la perception et de la représentationThe term hors-scène (“off-stage” with a dramaturgical and a scenographic meaning in French) is used in an empirical way to designate spaces, characters and or episodes that are invisible. It is not part of the technical vocabulary of the theater, and it is often replaced by words borrowed from other artistic fields such as “off”, or “out of frame”. Because of this lack of terminological precision, it is a notion that like a mirror reflects ideological and aesthetic orientations which can be related to a discourse that values the invisible, in opposition to an image-driven society. This notion of hors-scène is addressed through a study of the works of three major authors of the second half of the 20th Century: Marguerite Duras, Bernard-Marie Koltès and Jean-Luc Lagarce. Each one of them has his/her specific mode of blurring the lines between the stage and the off-stage, thus producing staging and making scenographies that have to tackle the redefinition of the limits of space and of representation itself. In their works, the boundary between the visible and the invisible no longer coincides with the articulation between the stage and an adjacent peripheral space. The hors scène is mobile and cannot be easily located : it can no longer be considered as what lies outside of the stage. It can be situated at the heart of the visible ; it can spring from a framing choice which orchestrates the relations between the stage, the house and the world, but also from a staging choice that materialises “timelessness”. It reveals itself discontinuously, through breaches opened up in a diversity of ways in a dramatic and/or scenic space whose boundaries themselves are in flux. The thesis identifies the dramaturgic and scenographic stakes of the uses of the hors-scène in the three authors' texts, as well as in a selection of stagings from the second half of the 20th Century and early 21st Century, as well as in scenographies and a number of sound/audio productions to which they are associated. The aim is to trace different categories of the hors-scène and to define more precisely this notion that could very well highlight a change in the modes of perception and representation

Full textAbstract:
La recherche d’espaces dépouillés est l’un des grands marqueurs de l’évolution de la scénographie au XXe siècle. De même que pour les arts plastiques, cette tension vers le vide est associée à la redéfinition des formes dans leur mutation moderne et postmoderne. Plateaux nus et espaces vides constituent deux modalités particulières de cette recherche de l’épure. Le plateau nu débarrasse la scène du décor et de son appareil illusionniste et resserre la représentation sur la présence d’un acteur et l’écoute du texte. D’abord solution pratique, rupture avec un théâtre commercial et bourgeois, le plateau nu est ancré dans une conception éthique du théâtre. Cette première partie de l’étude se fonde sur les espaces de Jacques Copeau, Jean Vilar, Antoine Vitez et Christian Schiaretti. L’espace vide, étudié à travers le travail de Peter Brook, Claude Régy, Joël Pommerat et Nacera Belaza cherche à construire un ailleurs. Cette étude propose d’étudier le succès contemporain des esthétiques scéniques du vide et du dépouillement. Aujourd’hui, le plateau nu est devenu un patrimoine, portant en lui les valeurs du théâtre public et s’associant implicitement à une célébration de ses pionniers, Jacques Copeau et Jean Vilar. L’espace vide, vu à travers les traditions orientales se charge d’une spiritualité, et est aussi perçu comme l’au-delà mental de la représentation. Espaces vides et plateaux nus, s’ils ont pu naître de contraintes économiques sont aujourd’hui devenus des espaces luxueuxThe research of concise spaces is one of the marks of the scenography evolution on the 20th century. As in the visual arts, this mouvement towards to the void is associated with a redefinition of the forms in their modern and postmodern mutations. Naked stages and empty spaces constitute two particular modalities of research of an uncluttered style. The naked stage removes the scenery and the scenic illusion from the stage to focus its representation on the actor and the text. Starting as a practical solution and rupture with commercial and bourgeois theater, the naked stage is anchored in an ethical conception of theater. This first part of this study is based on the spaces according to Jacques Copeau, Jean Vilar, Antoine Vitez and Christian Schiaretti. The empty space seeks to find new horizons, examined through the concepts of space by Peter Brook, Claude Régy, Joël Pommerat and Nacera Belaza. This study proposes to examine the contemporary success of aesthetic scenics based on void and bareness. The naked stage has become nowadays a heritage, carrying values of public theater, and being implicitly associated with a celebration of its pioneers Jacques Copeau and Jean Vilar. Seen throughout eastern traditions, the empty stage is filled with spirituality and thus becomes a mental hereafter of the representation. Initially consequence of an economical imposition, naked stages and empty spaces have become luxurious spaces nowadays

We consider the problem of robustness, in particular that of robust stability. Such a problem is amenable to analysis by frequency domain techniques, and also using state space methods. Using some recent state space theory yielding the exact radius of the ball around a nominally stable system within which all additive perturbations retain stability, we show how control action may be implemented to increase the radius of this ball. We present further some material on how destabilizing perturbations may be constructed from solutions of Riccati equations, and how the above mentioned radii may be found with respect to an alternative norm to the one used above. Finally we give some remarks on the use of Lyapunov functions for systems.

Full textAbstract:
Reinforcement learning in the continuous state-space poses the problem of the inability to store the values of all state-action pairs in a lookup table, due to both storage limitations and the inability to visit all states sufficiently often to learn the correct values. This can be overcome with the use of function approximation techniques with generalisation capability, such as artificial neural networks, to store the value function. When this is applied we can select the optimal action by comparing the values of each possible action; however, when the action-space is continuous this is not possible. In this thesis we investigate methods to select the optimal action when artificial neural networks are used to approximate the value function, through the application of numerical optimization techniques. Although it has been stated in the literature that gradient-ascent methods can be applied to the action selection [47], it is also stated that solving this problem would be infeasible, and therefore, is claimed that it is necessary to utilise a second artificial neural network to approximate the policy function [21, 55]. The major contributions of this thesis include the investigation of the applicability of action selection by numerical optimization methods, including gradient-ascent along with other derivative-based and derivative-free numerical optimization methods,and the proposal of two novel algorithms which are based on the application of two alternative action selection methods: NM-SARSA [40] and NelderMead-SARSA. We empirically compare the proposed methods to state-of-the-art methods from the literature on three continuous state- and action-space control benchmark problems from the literature: minimum-time full swing-up of the Acrobot; Cart-Pole balancing problem; and a double pole variant. We also present novel results from the application of the existing direct policy search method genetic programming to the Acrobot benchmark problem [12, 14].

In this thesis, I explore a novel algorithm to model the joint behavior of multiple correlated signals. Our chosen example is the ECG (Electrocardiogram) and ABP (Arterial Blood Pressure) signals from patients in the ICU (Intensive Care Unit). I then use the generated models to predict blood pressure levels of ICU patients based on their historical ECG and ABP signals. The algorithm used is a variant of a Hidden Markov model. The new extension is termed as the Latent State Space Copula Model. In the novel Latent State Space Copula Modelthe ECG, ABP signals are considered to be correlated and are modeled using a bivariate Gaussian copula with Weibull marginals generated by a hidden state. We assume that there are hidden patient "states" that transition from one hidden state to another driving a joint ECG-ABP behavior. We estimate the parameters of the model using a novel Gibbs sampling approach. Using this model, we generate predictors that are the state probabilities at any given time step and use them to predict a patient's future health condition. The predictions made by the model are binary and detects whether the Mean arterial pressure(MAP) is going to be above or below a certain threshold at a future time step. Towards the end of the thesis I do a comparison between the new Latent State Space Copula Model and a state of the art Classical Discrete HMM. The Latent State Space Copula Model achieves an Area Under the ROC (AUROC) curve of .7917 for 5 states while the Classical Discrete HMM achieves an AUROC of .7609 for 5 states.

Full textAbstract:
This thesis is concerned with state estimation in partially observed diffusion processes with discrete time observations. This problem can be solved exactly in a Bayesian framework, up to a set of generally intractable stochastic partial differential equations. Numerous approximate inference methods exist to tackle the problem in a practical way. This thesis introduces a novel deterministic approach that can capture non normal properties of the exact Bayesian solution. The variational approach to approximate inference has a natural formulation for partially observed diffusion processes. In the variational framework, the exact Bayesian solution is the optimal variational solution and, as a consequence, all variational approximations have a universal ordering in terms of optimality. The new approach generalises the current variational Gaussian process approximation algorithm, and therefore provides a method for obtaining super optimal algorithms in relation to the current state-of-the-art variational methods. Every diffusion process is composed of a drift component and a diffusion component. To obtain a variational formulation, the diffusion component must be fixed. Subsequently, the exact Bayesian solution and all variational approximations are characterised by their drift component. To use a particular class of drift, the variational formulation requires a closed form for the family of marginal densities generated by diffusion processes with drift components from the aforementioned class. This requirement in general cannot be met. In this thesis, it is shown how this coupling can be weakened, allowing for more flexible relations between the variational drift and the variational approximations of the marginal densities of the true posterior process. Based on this revelation, a selection of novel variational drift components are proposed.

This thesis explores the use of State-Space models in Time Series Analysis and Forecasting, with particular reference to the Dynamic Linear Model (DLM) introduced by Harrison and Stevens. Concepts from Control Theory are employed, especially those of observability, controllability and filtering, together with Bayesian inference and classical forecasting methodology. First, properties of state-space models which depart from the usual Gaussian assumptions are examined, and the predictive consequences of such models are developed. These models can lead to new phenomena, for example it is shown that for a wide class of models which have a suitably defined steady evolution the usual properties of classical steady models (such as exponentially weighted moving averages) do not apply. Secondly, by considering the forecast functions, equivalence theorems are proved for DLMs in the steady state and stationary Box-Jenkins models. These theorems are then extended to include both time-varying and non-stationary models thus establishing a very general predictor equivalence. However it is shown that intuitively appealing DLMs which have diagonal covariance matrices are restricted by only covering part of the equivalent stability / invertibility region, and examples are given to illustrate these points. Thirdly, some problems of inference involving state-space models are looked at, and new approaches outlined. A class of collapsing procedures based upon a distance measure between posterior components is introduced. This allows the use of non-normal errors or Harrison-Stevens Class II models by condensing the normal-mixture posterior distribution to prevent an explosion of information with time, and avoids some of the problems of the Harrison-Stevens solution. Finally, some examples are given to illustrate the way in which some of these models and collapsing procedures might be used in practice.

Much work has been done on the problem of stochastic modeling for the evaluation of performance, dependability and performability properties of systems, but little attention has been given to the interplay between the model and the performance measure of interest. Our work addresses the problem of automatically constructing Markov processes tailored to the structure of the system and the nature of the performance measures of interest. To solve this problem, we have developed new techniques for detecting and exploiting symmetry in the model structure, new reward variable specification techniques, and new state-space construction procedures. We propose a new method for detecting and exploiting model symmetry in which (1) models retain the structure of the system, and (2) all symmetry inherent in the structure of the model can be detected and exploited for the purposes of state-space reduction. Then, we extend the array of performance measures that may be derived from a given system model by introducing a class of path-based reward variables, which allow rewards to be accumulated based on sequences of states and transitions. Finally, we describe a new reward variable specification formalism and state-space construction procedure for automatically computing the appropriate level of state-space reduction based on the nature of the reward variables and the structural symmetry in the system model.

The models are derived from the Doppler power spectral density using factorization and realization techniques. Several simulations are performed when the channel is Rayleigh and Ricean distributed under both flat and frequency-selective fading assumptions. The simulation studies illustrate the tracking properties of the inphase, quadrature and square envelope estimators for various received signal-to-noise ratios.

Full textAbstract:
Verifying system specifications using traditional model-checking techniques rapidly becomes infeasible as the complexity of the specification becomes non-trivial, due to the state-space explosion problem, wherein the representation of the behaviour of the system becomes too large to be practically constructable. Thus, we require techniques that collapse the state-space to a manageable size while still preserving the information required for verification of the desired properties. The concept of abstraction provides one effective means of combatting state-space explosion. Essentially, abstraction aims to simplify the behaviour by hiding details that are not directly relevant to the verification task. \Vithin the abstraction framework, the original behaviour ofthe system is known as the concrete behaviour, and the simplified behaviour the abstract.. The precise means of abstraction we consider acts by reducing the set of actions appec,tring in the abstract behaviour by means of a mapping from each of the set of concrete actions to an abstract action (action renaming) or to the empty word (action hiding). It has been previously shown that when the abstraction fulfils a condition called weak continuation-cl~sure, then the abstract behaviour can be used to II decide whether, or not the concrete behaviour satisfies a property under a satisfaction relation called satisfaction within fairness, a relation that includes a built-in concept of fairness. The drawback is that the technique requires the construction of the original state-space, which is often infeasible. The main contribution of this thesis is to show that partial-order reduction can be combined with abstraction in such a way that the the abstraction can be used to decide whether the concrete behaviour satisfies a given property within fairness using only a partial-order reduced version of the state-space, which potentially could be orders of magnitude smaller than the full state-space. Attention is also paid to providing practical means for computing this partial-order reduction, and a couple of results in the field of compositional verification are presented.
