Innovations in Musical Texture and Aural Perspective: Steven Mackey's See Ya Thursday for Solo MarimbaHall, David Porter 08 1900 (has links)
This dissertation and accompanying lecture recital explore the unique textural features in the works of Steven Mackey as exhibited in See Ya Thursday (1993).A rigorous formal, harmonic, and motivic analysis will highlight the compositional characteristics of textural structure and aural perspective that exist in the work. Illumination of these compositional elements can help to identify and minimize the technical complexities that exist within this piece for the performer. In addition, this document provides brief biographical information on Steven Mackey and his works, and on See Ya Thursday as it relates to other pieces in the advanced marimba literature. Finally, it is the aim of the author to add a resource to the relatively limited amount of research on Steven Mackey with this analysis of See Ya Thursday.

Les approches chaos-stochastiques du risque de marché / Chaos-stochastics approaches of market riskHennani, Rachida 10 December 2015 (has links)
La complexité des marchés financiers et la recrudescence des crises particulièrement sévères contribuent à l'évolution et à la remise en cause de modèles économétriques dits standards dans l'explication et la prévision des dynamiques financières. L'alerte donnée conjointement par les responsables prudentiels et les chercheurs vise à encourager le développement de modèles plus complexes, non linéaires et largement inspirés d'autres disciplines. Nous soutenons dans cette thèse l'idée qu'une approche chaos-stochastique des chroniques financières est susceptible de conduire à de meilleurs résultats. La pertinence de cette association est évaluée pour le risque de marché dans deux cadres d'analyse distincts. Nous montrons tout l'intérêt d'une synthèse des modèles chaotiques et des spécifications GARCH avec ou sans changements de régimes markoviens (MRS) pour la modélisation et la prévision de la Value-at-Risk des indices boursiers de la zone euro. Il ressort de cette étude de meilleurs résultats des modèles chaos-stochastiques et dans le cas des spécifications MRS-GARCH, une meilleure adéquation du modèle chaotique de Lasota(1977) pour les indices de l'Europe du Sud, particulièrement plus volatiles que ceux de l'Europe du Nord pour lesquels nous recommandons le modèle de Mackey-Glass(1977). Cette combinaison permet, dans un cadre bivarié, de mieux appréhender les liens qui existent entre les différentes places boursières de la zone euro. Nous introduisons deux nouvelles spécifications qui intègrent les problématiques liées aux ruptures de corrélations : la première permet de distinguer, par une analyse en sous-périodes, les relations d'interdépendance par rapport aux phénomènes de contagion et la seconde propose, dans un cadre unifié, d'intégrer les ruptures de corrélations. Cette double analyse met en évidence le rôle moteur du couple d'indices franco-allemand, l'existence de deux sphères distinctes constituées d'une part par les indices de l'Europe du Nord et d'autre part par les pays de l'Europe du Sud et l'intensification de certaines relations entre indices suite à la crise des dettes souveraines. Nous constatons et insistons sur la pertinence d'un modèle chaotique en moyenne pour rendre compte d'une part de la volatilité attribuée, à tort, aux effets GARCH. / The complexity of financial markets and the resurgence of severe crises contribute to the skepticism and evolution of standard econometric models in the explanation and prediction of financial time series. The warning given jointly by prudential authorities and researchers aims to encourage the development of nonlinear and more complex models inspired by other disciplines. I argue in this thesis that a chaos-stochastic approach of financial dynamics is likely to lead to better results. The relevance of this association is evaluated for market risk in two distinct analytical frameworks. I show the improvements given by a synthesis of chaotic models and GARCH specifications with or without Markov Regime Switching (MRS) for modelling and predicting the Value-at-Risk of 7 mains index of Monetary and Economic Union. It appears, from this study, better results from chaos-stochastic models. In the case of the MRS-GARCH specifications, I find more adequacy of the chaotic model of Lasota (1977) for the indices of Southern Europe, which are especially more volatile than those of Northern Europe for which I recommend the model of Mackey-Glass (1977). This combination allows, in a bivariate framework, to provide information on the relationship between these different indices. I introduce two new specifications that integrate issues related to correlation breakdowns. The first distinguishes, by a sub-periods analysis, the relations of interdependence of contagious relationships. Meanwhile, the second provides, in a unified framework, an integration of correlations breakdowns. These two analyses imply It appears from this double analysis the leading role of the Franco-German duo, the existence of two distinct spheres formed in a part by the Northern European indices and in another part by countries of the Southern Europe, and the intensification of relations between some indices following the sovereign debt crisis. Finally, these results support the relevance of a chaotic model which may account for some volatilities that are, wrongly, attributed to GARCH effects.

Drum Music: A Performance Guide and Discussion of John Mackey's Influential Concerto for the Modern PercussionistMcWilliams, Chris 08 1900 (has links)
John Mackey is an influential and prolific composer of wind band literature. His focus on and exploration of the percussion section are defining characteristics of his compositional voice. Mackey's concerto for percussion and wind band, "Drum Music," is a perfect example of his exploitation of the myriad timbres available within the percussion family, and also serves to showcase the versatility required of a modern percussionist. This dissertation and accompanying lecture recital provide a comprehensive guide for performers of the work. Major aspects of Mackey's compositional approach are discussed with emphasis placed on his use of percussion throughout his works. Analysis and performance concerns are discussed for each of the concertos three movements, and information is provided on the reduced version of the work prepared as part of this study.

JOHN MACKEY’S WINE-DARK SEA: SYMPHONY FOR BAND A DISCOURSE AND ANALYSIS OF JOHN MACKEY’S SYMPHONY FOR BANDSweet, Jonathan C. 01 January 2019 (has links)
John Mackey’s Wine-Dark Sea: Symphony for Band(2014) is a work of epic proportions and was the winner of the William D. Revelli Composition Contest of the National Band Association in 2015. Wine-Dark Sea: Symphony for Bandhas received much acclaim and many performances including a recording by the University of Texas Wind Ensemble in 2016.
The purposes of this dissertation are 1) to provide historical information on the genesis of the work through interviews with its composer, John Mackey, and commissioning director, Jerry Junkin; 2) to provide an analysis of how the programmatic elements of Homer’s Odysseyinteract with the musical aspects of the work.
The first chapter discusses biographical information essential to the understanding of John Mackey’s music. Chapter two includes information specific to the creation of Wine-Dark Sea: Symphony for Band. Chapters three through five provide analytical information alongside programmatic information to provide a clear understanding of how the music and programmatic elements combine to create the work. Chapter six concludes the document with some performance suggestions for the conductor.
An appendix of information including graphs of how dynamic range corresponds to programmatic elements and interviews with the composer, John Mackey, and the commissioner, Jerry Junkin, are also provided.

Constrained Motion Particle Swarm Optimization for Non-Linear Time Series PredictionSapankevych, Nicholas 13 March 2015 (has links)
Time series prediction techniques have been used in many real-world applications such as financial market prediction, electric utility load forecasting, weather and environmental state prediction, and reliability forecasting. The underlying system models and time series data generating processes are generally complex for these applications and the models for these systems are usually not known a priori. Accurate and unbiased estimation of time series data produced by these systems cannot always be achieved using well known linear techniques, and thus the estimation process requires more advanced time series prediction algorithms.
One type of time series interpolation and prediction algorithm that has been proven to be effective for these various types of applications is Support Vector Regression (SVR) [1], which is based on the Support Vector Machine (SVM) developed by Vapnik et al. [2, 3]. The underlying motivation for using SVMs is the ability of this methodology to accurately forecast time series data when the underlying system processes are typically nonlinear, non-stationary and not defined a-priori. SVMs have also been proven to outperform other non-linear techniques including neural-network based non-linear prediction techniques such as multi-layer perceptrons.
As with most time series prediction algorithms, there are typically challenges associated in applying a given heuristic to any general problem. One difficult challenge in using SVR to solve these types of problems is the selection of free parameters associated with the SVR algorithm. There is no given heuristic to select SVR free parameters and the user is left to adjust these parameters in an ad hoc manner.
The focus of this dissertation is to present an alternative to the typical ad hoc approach of tuning SVR for time series prediction problems by using Particle Swarm Optimization (PSO) to assist in the SVR free parameter selection process. Developed by Kennedy and Eberhart [4-8], PSO is a technique that emulates the process living creatures (such as birds or insects) use to discover food resources at a given geographic location. PSO has been proven to be an effective technique for many different kinds of optimization problems [9-11].

La catégorie Fquad des foncteurs de Mackey généralisés pour les formes quadratiques sur F_2Vespa, Christine 12 December 2005 (has links) (PDF)
Le but de ce travail est de construire et d'étudier des catégories de foncteurs associées aux espaces vectoriels munis de formes quadratiques non dégénérées sur F_2. Après avoir construit la catégorie de foncteurs Fquad, en utilisant des techniques similaires à celles utilisées pour les foncteurs de Mackey, on obtient plusieurs résultats concernant les objets simples de cette catégorie. <br /><br />On montre l'existence d'un foncteur, noté i, de F dans Fquad exact, fidèle et préservant les simples, où F est la catégorie des foncteurs entre la catégorie des espaces vectoriels finis sur F_2 et la catégorie de tous les espaces vectoriels.<br /><br />On introduit une autre catégorie de foncteurs, notée Fiso, dont les objets simples sont indexés par les représentations modulaires irréductibles des groupes orthogonaux, éventuellement dégénérés, sur F_2 et on montre l'existence d'un foncteur, noté k, de Fiso dans Fquad exact, fidèle et préservant les simples.<br /><br />En décomposant les deux générateurs projectifs les plus simples de la catégorie Fquad on obtient une classification des ``petits'' objets simples de Fquad qui nous permet de montrer que les foncteurs polynomiaux de Fquad sont dans l'image du foncteur i. De nouveaux foncteurs de Fquad, baptisés foncteurs mixtes, apparaissent dans la décomposition de ces deux générateurs projectifs et fournissent deux familles infinies de foncteurs simples de Fquad ne provenant ni de F, ni de Fiso.
