A History of the Florida Philharmonic and an Original Composition: Symphony No. 2 . (Original Composition);

This dissertation is in two parts. The first part is a monograph which presents a history of the first fully professional orchestra in Miami. The Florida Philharmonic was founded in 1965 and ceased operations in 1982. Appendices provide lists of the programs which the orchestra performed. The second part is an original composition entitled Symphony No. 2. The symphony is scored for piccolo, two flutes, two oboes, English Horn, two clarinets (in B-flat), two bassoons, contrabassoon, four horns (in F), trumpet (in B-flat), three trombones, tuba, timpani, two vibraphones, gong, suspended cymbal, sizzle cymbal, marimba, wind chimes, orchestra bells, finger cymbals, triangle, snare drum, crash cymbals, xylophone, bass drum, celesta, piano, and strings. The symphony has four movements which combine contemporary compositional techniques with traditional forms. The first movement is in sonata form with an introduction. The second movement (a scherzo) is a rondo. The form of the third movement is A B A. The fourth movement is a two-part form. While the second part uses material from the first part in retrograde, it also contains a restatement of the introduction leading to a codetta

Comparison of the current LHC Collimators and the SLAC Phase 2 Collimator Impedances

One of the key sources of transverse impedance in the LHC has been the secondary graphite collimators that sit close to the beam at all energies. This limits the stable bunch intensity due to transverse coupled-bunch instabilities and transverse mode coupling instability. To counteract this, new secondary collimators have been proposed for the phase II upgrade of the LHC collimation system. A number of designs based on different jaw materials and mechanical designs have been proposed. A comparison of the beam coupling impedance of these different designs derived from simulations are presented, with reference to the existing phase I secondary collimator design

Evaluation of the Beam Coupling Impedance of New Beam Screen Designs for the LHC Injection Kicker Magnets

During the 2011 run of the LHC there was a significant measured temperature increase in the LHC Injection Kicker Magnets (MKI) during operation with 50ns bunch spacing. This was due to increased beam-induced heating of the magnet due to beam impedance. Due to concerns about future heating with the increased total intensity to nominal and ultimate luminosities a review of the impedance reduction techniques within the magnet was required. A number of new beam screen designs are proposed and their impedance evaluated. Heating estimates are also given with a particular attention paid to future intensity upgrades to ultimate parameters

Testing for a Unit Root in Panels with Dynamic Factors

This paper studies testing for a unit root for large n and T panels in which the cross-sectional units are correlated. To model this cross-sectional correlation, we assume that the data is generated by an unknown number of unobservable common factors. We propose unit root tests in this environment and derive their (Gaussian) asymptotic distribution under the null hypothesis of a unit root and local alternatives. We show that these tests have significant asymptotic power when the model has no incidental trends. However, when there are incidental trends in the model and it is necessary to remove heterogeneous deterministic components, we show that these tests have no power against the same local alternatives. Through Monte Carlo simulations, we provide evidence on the finite sample properties of these new tests.Cet article analyse des tests de racines unitaires dans les panels où n et T sont tous les deux rands et où les unités d’observations sont corrélées. Cette corrélation transversale est modélisée à l’aide d’un modèle à facteurs dynamiques inobservables. Nous proposons plusieurs tests dans cet environnement et dérivons leurs lois limites sous l’hypothèse nulle d’une racine unitaire et des alternatives locales. Nous mon-trons aussi que ces tests n’ont pas de puissance contre ces mêmes alternatives locales lorsqu’il est nécessaire d’estimer des composantes déterministes. À l’aide d’une expérience de Monte Carlo, nous comparons les propriétés en échantillons finis de ces tests et de d’autres suggérés dans la littérature

Beyond Panel Unit Root Tests: Using Multiple Testing to Determine the Non Stationarity Properties of Individual Series in a Panel

Most panel unit root tests are designed to test the joint null hypothesis of a unit root for each individual series in a panel. After a rejection, it will often be of interest to identify which series can be deemed to be stationary and which series can be deemed nonstationary. Researchers will sometimes carry out this classification on the basis of n individual (univariate) unit root tests based on some ad hoc significance level. In this paper, we demonstrate how to use the false discovery rate (FDR) in evaluating I(1)=I(0) classifications based on individual unit root tests when the size of the cross section (n) and time series (T) dimensions are large. We report results from a simulation experiment and illustrate the methods on two data sets

The Seemingly Unrelated Dynamic Cointegration Regression Model and Testing for Purching Power Parity

This paper studies seemingly unrelated linear models with integrated regressors and stationary errors. By adding leads and lags of the first differences of the regressors and estimating this augmented dynamic regression model by feasible generalized least squares using the long-run covariance matrix, we obtain an efficient estimator of the cointegrating vector that has a limiting mixed normal distribution. Simulation results suggest that this new estimator compares favorably with others already proposed in the literature. We apply these new estimators to the testing of purchasing power parity (PPP) among the G-7 countries. The test based on the efficient estimates rejects the PPP hypothesis for most countries.Cet article analyse les modèles de régressions empilées avec régresseurs intégrés et erreurs stationnaires. En ajoutant des retards et des avances des premières différences des régresseurs et en estimant le modèle qui en résulte par moindres carrés quasi-généralisés, nous obtenons un estimateur efficace du vecteur de coïntégration qui a une loi limite normale mixte. Les résultats de simulation suggèrent que ce nouvel estimateur se compare favorablement aux autres déjà proposés dans la littérature. Ce nouvel estimateur est utilisé pour tester la théorie de la parité des pouvoirs d'achat (PPA) parmi les pays du G-7. Le test nous permet de rejeter l'hypothèse nulle de la parité des pouvoirs d'achat pour la plupart des pays

Coaxial Wire Measurements of Ferrite Kicker Magnets

Fast kicker magnets are used to inject beam into and eject beam out of the CERN accelerator rings. These kickers are generally transmission line type magnets with a rectangular shaped aperture through which the beam passes. Unless special precautions are taken the impedance of the yoke can provoke significant beam induced heating, especially for high intensities. In addition the impedance may contribute to beam instabilities. The results of longitudinal and transverse impedance measurements, for various kicker magnets, are presented and compared with analytical calculations: in addition predictions from a numerical analysis are discussed

Dense suspension of solid particles as a new heat transfer fluid for concentrated solar thermal plants: on-sun proof of concept

This paper demonstrates the capacity of dense suspensions of solid particles to transfer concentrated solar power from a tubular receiver to an energy conversion process by acting as a heat transfer fluid. Contrary to a circulating fluidized bed, the dense suspension of particles’ flows operates at low gas velocity and large solid fraction. A single-tube solar receiver was tested with 64 µm mean diameter silicon carbide particles for solar flux densities in the range 200–250 kW/m2, resulting in a solid particle temperature increase ranging between 50 °C and 150 °C. The mean wall-to-suspension heat transfer coefficient was calculated from experimental data. It is very sensitive to the particle volume fraction of the suspension, which was varied from 26 to 35%, and to the mean particle velocity. Heat transfer coefficients ranging from 140 W/m2 K to 500 W/m2 K have been obtained, thus corresponding to a 400 W/m2 K mean value for standard operating conditions (high solid fraction) at low temperature. A higher heat transfer coefficient may be expected at high temperatures because the wall-to-suspension heat transfer coefficient increases drastically with temperature. The suspension has a heat capacity similar to a liquid heat transfer fluid, with no temperature limitation but the working temperature limit of the receiver tube. Suspension temperatures of up to 750 °C are expected for metallic tubes, thus opening new opportunities for high efficiency thermodynamic cycles such as supercritical steam and supercritical carbon dioxide
