Circular orientation in performance: a study of the cycle of living and its application in the cultural expression like dance

Ngema, Vusabantu January 2009 (has links)
Submitted in fulfillment of the requirements for the degree Of DOCTOR OF PHILOSOPHY In the Department of IsiZulu Namagugu At the University of Zululand, 2009. / This study focuses on the circular orientation in performances by Abathwa and Abantu speaking people of central and southern Africa. This notion is explored through close examination of space, movements, time and objects used during ritual and recreational performances. The study is informed by the meaning contained in symbolism rooted in Africans’ perception of culture, religion, language, cosmos, science and artistic aesthetics. The first chapter is the general introduction to the study covering aspects such as statement of the problem and hypothesis, rationale, methodology and literature review. It also attempts to give an in depth explanation of the African conception of the circle, the centre and the cycle. It explains how these three concepts are applied in social structure, architecture and ritual performances. The chapter also explains the African cyclical perception of time and life. The second chapter looks at the historical perspective of dance performances by indigenous peoples of southern Africa. The histories and the cultural backgrounds of the Khoisan and the Bantu speaking people, form the bases for the interpretation and understanding of dance performances during rituals, recreation and children games. The third chapter investigates the thematic approach towards the interpretation of dance performances by the Bantu and the Khoisan speaking people of Africa. The emphasis is on the theme of gender and sexuality since it is the theme that plays a central role in most of the ritualistic performances among the Africans. While the emphasis on relationship between genders in the performances, the attention is also paid towards the metaphoric, symbolic and paradoxical representations of African world view through the juxtaposition of gender and sexuality during performances. The fourth chapter examines the use of elements of dance performances in relation to themes of fertility (human and soil) and curing. These themes are discussed because they are the themes that apply to all the people being studied where as themes such as animal (hunting) and acrobatic (masks) can only apply to certain peoples not to the other for one reason or the other. The fifth chapter deals with the aesthetic principles as they apply to African dance forms and performances. It focuses on the application of the elements of space and symbolism contained in other elements of performance such as timing, costume, crafts and objects. The sixth chapter is an investigation of the circular orientation in modern performances and children games. It also examines the continuation of the circular orientation in religious worship-performances. The seventh/the last chapter is about the findings, recommendations and the general conclusion of the study.

Mécanismes d'accès multiple dans les réseaux sans fil large bande / Multiple Access Mechanisms in Broadband Wireless Networks

Ragaleux, Alexandre 22 September 2016 (has links)
Dans cette thèse, nous étudions le problème de l'allocation de ressources dans le cadre des réseaux 4G LTE. La méthode d'accès OFDMA qui est utilisée partage les ressources radios à la fois dans le domaine fréquentiel et temporel. En raison des déficiences du canal, les utilisateurs ne bénéficient pas toujours des mêmes débits d'émission/réception sur chacune des ressources. Dans ce cadre, notre problème consiste à distribuer ces ressources radios aux mobiles afin de leur permettre de transmettre/recevoir des données. L'algorithme utilisé pour allouer les ressources a une importance fondamentale sur les performances du système. La norme LTE ajoute des contraintes supplémentaires à ce problème et rend l'exploitation de la diversité fréquentielle et de la diversité multi-utilisateurs plus difficile. En effet, sous ces contraintes, nous montrons que le problème de l'allocation de ressources fait alors partie de la classe des problèmes « difficiles ». Par conséquent, les algorithmes classiques de la littérature sont souvent inadaptés à un réseau LTE réel. Nous proposons des algorithmes d'allocation de ressources à la fois pour le sens montant et descendant de LTE. Les contraintes de la norme sont rigoureusement prises en compte afin de construire des solutions efficaces. De plus, les algorithmes proposés sont génériques et peuvent donc s'adapter à une grande variété d'objectifs. En particulier, nous nous attachons à prendre en charge les trafics multimédias dont les débits et les besoins en qualité de service sont très hétérogènes (taux d’erreurs binaires, retard, gigue, etc.). En effet, l'augmentation progressive des débits et la forte popularité des équipements mobiles intelligents amènent à une utilisation toujours plus massive des applications multimédias. Tous nos algorithmes sont validés par simulation. Par ce biais, nous montrons que la prise en compte des contraintes de LTE est essentielle à l'obtention de performances élevées. / In this thesis, we study the resource allocation problem within the framework of 4G LTE networks. The OFDMA access method divides the radio resources both in the frequency and time domains. Due to channel impairments, users do not always have the same transmit/receive rates on each resource. In this context, our problem is to share the radio resources between users and enable them to transmit/receive data. The algorithm used to allocate resources is of fundamental importance on system performance. The LTE standard adds constraints to this problem and makes harder the exploitation of the frequency and the multi-user diversity. Indeed, under these constraints, we show that the resource allocation problem becomes part of the « most difficult » problems. Therefore, the conventional algorithms are often not adapted to a real LTE network. We provide resource allocation algorithms for both the uplink and downlink of LTE. The constraints of the standard are rigorously taken into account in order to build effective solutions. In addition, the proposed algorithms are generic and can adapt to a wide variety of objectives. In particular, we focus on the support of multimedia traffic with heterogeneous quality of service requirements (bit error rate, delay, jitter, etc.). Indeed, the gradual increase of the offered throughput and the strong popularity of smart mobile devices lead to a massive use of multimedia applications. Our algorithms are validated through extensive simulation. By this means, we show that the inclusion of LTE constraints is essential to achieving high performance.

REVIEW OF THE CURRENT UNDERSTANDING OF MUSIC PERFORMANCE ANXIETY, ITS COMORBIDITIES, AVAILABLE TREATMENTS AND THEIR IMPLEMENTATION

Smith, Lucy, 0000-0002-6682-4518 January 2021 (has links)
The mental and physical health issues faced by musicians are multifaceted and generally poorly understood by most musicians, teachers and medical professionals. This monograph will provide students, educators, and institutions with a model to implement a proactive physical and mental health plan. If followed this should ensure a more positive and supportive environment for student musicians. Not only will this help students during their studies, but it will also equip them with resilience as they pursue their careers. Effectively incorporating health education and support within our education system will also benefit this generation of musicians, and every subsequent one. This will lead to a healthier environment within the music profession.In an ideal world, every music school would have a specialized team of health professionals to help address the issues faced by students, including Music Performance Anxiety and its comorbidities, such as anxiety and depression, along with Performance-Related Musculoskeletal Disorders. These common problems, many of which are inextricably linked to their chosen profession, are often dealt with poorly or ignored completely. As musicians, we study our instruments with specialists, at centers of excellence, doing research into the schools we apply for to get the best fit and highest level of education possible. The same priority should be given to our physical and mental health. Specialized treatment is available to musicians often at a prohibitive cost, creating barriers for many students. By introducing personalized care for music students within educational institutions, these resources become available to everyone who needs them. / Music Performance

Bodysnatching in Contemporary Anglophone Drama, 1996-2022

Gilovich-Wave, Ilana January 2023 (has links)
In this dissertation, I explore the ways in which contemporary theatre stages possibilities and crises of embodiment. In order to penetrate the complex relationships between character, performer, text, and production, I coin a critical term: theatrical bodysnatching. This term refers to a dissonance or power struggle made manifest in performance, in which a performer’s body seems to resist the character it inhabits in ways that enhance, rather than detract from, the thematics of a theatrical production. In order to demonstrate the power of theatrical bodysnatching, I analyze playtexts, theatrical performances, reviews, and performer interviews. I argue that theatre is a medium optimally suited for staging sociopolitical dialogue because it models a kind of self-reflexive critique, in which performing bodies both embrace and resist the demands of the playtext. As a result, theatre creates a provocatively charged experience for spectators and performers, in which both parties are thematically implicated in the aims and preoccupations of a given play. Just as the performer’s body does not dissolve but instead accomplishes the crucial work of ideological exposure, the audience also becomes a marked, integrated presence and source of commentary in these bodysnatching plays. In this dissertation, I harness a particular selection of Anglophone drama from the late 20th to early 21st century in order to demonstrate how the often uncanny, subversive nature of live performance allows for radical reconsiderations of embodiment. By examining the ways in which these strangely iterated characters— and the performers who portray them— unfold onstage, theatrical bodysnatching poses urgent questions of exploitation, agency, and resistance.

INTEGRATED DESIGN OF BINDER JET PRINT PRODUCED HYDRAULIC AUTOMATIC VALVE SYSTEM

Heming Liu (14380014) 18 January 2023 (has links)
<p>Binder jet printing (BJP) is an additive manufacturing (AM) method which has the potential to be applied to high annual volumes in the automotive industry. Binder jet printing provides an excellent opportunity to innovate transmission valve body components. The three-layer design and complex hydraulic control system channels of valve body housing formulated a new electro-hydraulic system with the brand-new features inherited from BJP. For the valve body, the features of BJP brought a revolutionary new idea for both the valves and hydraulic channel design. The spool valve was housed with a sleeve that integrates orifices and port controls. The hydraulic channel layout of the valve body assembly was greatly simplified and space-saving. The support components had also been replaced with a lightweight design while maintaining the same functionality. Integrated design of Binder jet print produced hydraulic automatic valve system presented an entirely new design, whose static performance was compared to that of the conventional 948TE ZF9HP48 transmission valve body. Similar performance indicated that a valve body design featuring BJP would have great potential for various industrial applications.</p>

Spectacular Native Performances: From the Wild West to the Tourist Site, Nineteenth Century to the Present

Scarangella, Linda 06 1900 (has links)
This dissertation engages with anthropological debates of the representation of Native peoples in performance through a series of comparative case studies that examine Native North American participation in Wild West shows. Using multi-sited ethnographic and ethnohistorical approaches, it investigates the experiences of some Native performers with the top Wild West shows historically (1885-1930), of three Mohawk families who performed in a variety of spectacles (early 1900s ), and of contemporary performers in Wild West show re-creations at EuroDisney (France) and Buffalo Bill Days (Sheridan, Wyoming, U.S.A). This research focuses on Native performers' perspectives and experiences in order to complicate the picture of exploitation and commercialization in this context. In this dissertation, rather than focusing solely on the production of stereotypes, I trace the extent and various forms of Native agency and expressions of identity through a series of encounters that occur in a Wild West show "contact zone." Drawing on the concept of transculturation, I argue that Native performers adopted and used contact zone encounters as a space to express their opinions or to maintain, express, and/or contest Native identity. I thus elucidate the various forms of agency that Native performers have wielded, whether expressive, communicative, performative, or agency of cultural projects. A "cultural projects" approach to agency considers Native performers own goals and social relationships in addition to the socio-political constraints and power relations that structure their lives. Native performers had their own cultural projects; they actively pursued the opportunities and benefits of working in Wild West shows. I argue that narratives of opportunity, success, and pride found in the employment encounter, in oral histories of Mohawk performers' experiences, and in interviews with contemporary performers, represent agency of cultural projects. Oral histories from Mohawk performers' descendants and their interpretations of the archival record were crucial for revealing and substantiating these alternative perspectives of Native experiences in Wild West shows and spectacles. / Thesis / Doctor of Philosophy (PhD)

Antonio María Valencia's "Dúo en forma de sonata": An International Approach to Colombian National Music

Villamil Gómez, Diego Esteban 05 1900 (has links)
Antonio María Valencia (1902-1952) was one of the leading Colombian composers, pianists, and educators of his generation. His Dúo en forma de sonata (1926) for violin and piano serves as an early example of the composer's aesthetic. According to the programmatic description he sent to his mother, the Dúo depicts Valencia's "indelible impressions" of his homeland. Through structural and harmonic analysis, I examine the piece in relation to the composer's informal programmatic description. The analysis argues that the work poetically re-creates the landscape of Valencia's birthplace region through an international language, devoid of Colombian folk rhythms and melodies. Valencia proposes a different perspective on Colombian music as an alternative to the use of folk-based music elements that were predominant to Colombian music during his lifetime.

A Performance Guide to Gervais-François Couperin's Offertoires

Yu, Yang Sun 05 1900 (has links)
This dissertation considers Gervais-François Couperin (1759-1826) and his offertories, providing a performance guide relevant to French organ literature of the beginning of the nineteenth century. To fulfill this purpose, the research is divided into five chapters and a conclusion. Chapter 1 is an introduction explaining the purpose of the research and significance of the research. Chapter 2 presents the Couperin Dynasty and their lineage at Saint-Gervais, as well as the evolution of the musical market in the middle of the eighteenth century in Paris, which influenced Gervais-François Couperin's Offertories. Chapter 3 to Chapter 6 present the performance guide to playing Gervais-François Couperin's offertories: Chapter 3 focuses on the significant development of the French organ building in the 1800s and the registration of Grand-Jeu. Chapter 4 deals with the addition of the pedal, and Chapter 5 focuses on embellishment using tremendo (tremolo) and arpegio (arpeggio). Lastly, Chapter 6 offers a guide for adding manual indications where the score did not include them or in places where ambiguities remained. Synthesizing these elements, a newly edited full score of Gervais-François Couperin's Offertory in G Minor is provided in Chapter 7 to exemplify this dissertation's conclusion.
