The Eastman Wind Ensemble is known as the pioneer ensemble of modern wind music in North America and abroad. Its founder and conductor, Frederick Fennell, was instrumental in facilitating the creation and performance of a large number of new works written for the specific instrumentation of the wind ensemble. Created in 1952, the EWE developed a new one-to-a-part instrumentation that could be varied based on the wishes of the composer. This change in instrumentation allowed for many more compositional choices when composing. The instrumentation was a dramatic shift from the densely populated ensembles that were standard in North America by 1952. The information on the EWE and Fennell is available at the Eastman School of Music’s Ruth Watanabe Archive. By comparing the repertory and instrumentation of the Eastman ensembles with other contemporary ensembles, Fennell’s revolutionary ideas are shown to be unique in the wind music community.

This dissertation divides into three parts: (a) design and research of asymmetric stepped impedance resonator (SIR); (b) design and fabrication of dual-band and ultra-wide band (UWB) bandpass filters (BPFs) and (c) design and fabrication of millimeter wave filters. (a)design and research of asymmetric stepped impedance resonator. In the first part of the dissertation, we propose an asymmetric SIR, and the effect of electrical length ratio and impedance ratio on the performance of frequency has been discussed in detail. The insertion loss and spurious can be controlled by the structural parameters of asymmetric SIR which decreases the length of resonator effectively and achieves the reduction of whole size. Additionally, this characterization of the asymmetric SIR can be extensively applied on the interconnection of RFIC. (b) design and fabrication of dual-band and ultra-wide band (UWB) filters. In the second part of the dissertation, we propose dual-band and UWB BPFs by using asymmetric SIRs. The designed dual-band BPF is conformed to the standard of wireless local area network (WLAN), and the designed UWB BPF is conformed to the standard that Federal Communications Commission (FCC) defined. The structural parameters of asymmetric SIR can be adjusted accurately by the theoretical equations we calculated. Then, the ideal performance can be achieved. (c) design and fabrication of millimeter wave filters. In the third part of the dissertation, we propose the design of millimeter wave filters fabricated by the standard of complementary metal-oxide semiconductor (CMOS). Asymmetric SIRs are used to design the microwave filter to estimate that the feasibility of system on chip (SoC). Finally, some suggestions are made in the future work on technology for system on chip (SoC).

This paper proposes novel PIFA and monopole designs for dual-band or multi-band wireless communications, especially for mobile phones and CF (compact flash) card. The dual-frequency designs for mobile phone mainly utilize one or more metal branch strips to excite two resonant modes. By tuning the dimensions of branch strips, the ratio of the antenna¡¦s first two resonant frequencies can be achieved to be about 2.0, which makes it very promising for 900/1800 MHz operations. In addition, the broadband and quad-band (AMPS/GSM/DCS/PCS) designs for mobile phone application are also proposed. The broadband antenna design, unlike the above-mentioned dual-frequency designs for operating at two separate resonant modes, is more suitable to cover several nearby communication bands (DCS/PCS/UMTS/WLAN 2.45 GHz). The quad-band antenna design utilizes a £k-shape matching bridge to achieve a wider bandwidth both in lower and higher bands. For CF Card application, the triangular chip antenna having one longer and one shorter strip lines can generate the lower and higher modes covering the WLAN 2.4 and WLAN 5.2/5.8 GHz bands. All the antenna designs proposed are very promising to be concealed within the housing of the mobile phones or CF card.

In this work¡Awe studied the strain effects on heavy hole (hh) and light hole (lh) bands of Zn1-xMnxSe/GaAs by photoreflectance (PR) spectroscopy . The Zn1-xMnxSe epilayers were grown on GaAs substrates by the MBE technique . There is a biaxial compressive strain exist in the epilayer, due to the different lattice constants between epilayers and substrates .The biaxial strain will shift hh and lh bands and lift the hh-lh degeneracy. In our experiment ,we found that the splitting of the hh and lh transition energies is almost lineally proportional to the Mn ion concentrations. It can be ascribed to the strain in the epilayer . We have also measured the PR of Zn0.96Mn0.04Se/GaAs at various temperatures , and analyzed the transition energy of different temperatures in terms of Varshni relation.

ITC/USA 2014 Conference Proceedings / The Fiftieth Annual International Telemetering Conference and Technical Exhibition / October 20-23, 2014 / Town and Country Resort & Convention Center, San Diego, CA / This paper describes a system framework for a multi-band, multi-mode software defined radio (MBMM SDR) being developed for next-generation telemetry applications. The system framework consists of the multi-band front-end (MBFE), the multi-mode digital radio (MMDR), and the configuration and control (C2) sub-systems. The MBFE consists of an L/S/C-band transceiver architecture that provides wideband operation, band selection, and channel tuning. The MMDR consists of the software and firmware components for high-speed digital signal processing for the telemetry waveforms. Finally, the C2 consists of the software and hardware components for system configuration, control and status. The MBFE is implemented as a standalone hardware sub-system, while the MMDR and C2 are integrated into a single hardware subsystem that utilizes state-of-the-art system-on-chip (SoC) technology. Design methodologies, hardware architectures, and system tradeoffs are highlighted to meet next-generation telemetry requirements for improved spectrum efficiency and utilizations.

ITC/USA 2012 Conference Proceedings / The Forty-Eighth Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2012 / Town and Country Resort & Convention Center, San Diego, California / The Serial Streaming Telemetry infrastructure is being augmented with the Telemetry Network System, which is a net-centric infrastructure requiring bi-directional communications between the test article segment and the ground station segment. As a result, future radio segments must implement transceiver architecture to support bi-directional communications. This paper presents a design methodology for a multi-band transceiver design. The design methodology is based upon the Weaver architecture to provide coarse selection between the telemetry bands. Utilization of the Weaver architecture allowed for the optimization of multiple transmitter and receiver channels into single channels to support the L/S/C-Band frequency allocations. System-level simulation is presented to evaluate the feasibility of the transceiver design for a multi-band, multi-mode software-defined radio (SDR) platform in support of Telemetry Network System.

Elastic Wave propagation in structures with irregular boundaries is studied by transforming the plates with irregular surfaces to sinusoidal wave-guides. Guided elastic wave in a two-dimensional periodically corrugated plate is studied analytically. The plate material is considered as homogeneous, isotropic and linearly elastic. In a periodically corrugated wave-guide, all possible spectral orders of wave numbers are considered. The dispersion equation is obtained by applying the traction free boundary conditions at the two surfaces. The analysis is carried out in the wave-number domain for both symmetric and anti-symmetric modes. Non-propagating 'stop bands' and propagating 'pass bands' are investigated. Experimental analyses with two different pairs of transducers are also performed and compared with the results from the mathematical analysis. Newly developed semi-analytical DPSM technique has been also adopted in this dissertation to model the ultrasonic field in sinusoidally corrugated plate. Distributed Point Source Method (DPSM) is gradually gaining popularity in the field of Non-Destructive Evaluation (NDE). DPSM can be used to calculate the ultrasonic field (pressure, velocity and displacement in a fluid or stress and displacement in a solid) generated by ultrasonic transducers. So far the technique has been used to model ultrasonic field in homogeneous or multilayered fluid structures. In this dissertation the method is extended to model the ultrasonic field generated in both fluid and solid media. The Prime objective of using DPSM technique in this dissertation is to model the ultrasonic field generated in the corrugated wave guide. This method has never been used to model ultrasonic field in solids. Development of stress and displacement Green's functions in solids are presented. In addition to the wave propagation problem in the sinusoidal wave guide, a few unsolved problems such as ultrasonic field generated by bounded acoustic beams in multilayered fluid structures, near a fluid-solid interface and in flat solid isotropic plates are also presented in this dissertation.

The brass band and wind band had similar repertoires in the nineteenth and early twentieth centuries with marches, dances, solos, and transcriptions written prominently for both ensembles. The repertoires diverged at the beginning of the twentieth century as brass band contests commissioned new and original works and international composers began writing serious works for wind band. In the 1970s, British composer Philip Sparke succeeded in writing music for both ensembles and subsequently began to create a shared repertoire, and other composers started contributing to this repertoire. As this repertoire has proliferated, much of it has become worthy of serious study. The purpose of the current study is to find shared scoring tendencies between three transcriptions: one written by the original composer; a second transcribed by a different composer; and a third transcribed by both the original composer and a different composer. The works selected were The Year of the Dragon by Philip Sparke (transcribed by the composer), Variations for Brass Band by Ralph Vaughan Williams (transcribed by Donald Hunsberger), and Call of the Cossacks by Peter Graham (transcribed by the composer and Mick Dowrick). There were several effective instrumentation choices the works shared, including woodwind prominence in solo and lyrical passages, double reeds substituting for small brass ensembles, and high woodwinds written one or more octaves above the original. Adapting these choices, the author created a transcription of Gypsy Dream, the second movement of Call of the Cossacks. Further, these commonalities can serve as guidelines for other transcribers to arrange brass band works for wind band and expand this shared repertoire.

The purpose of this study was to: (a) investigate through exploration and inquiry, (b) trace by way of chronology, and (c) report in detail by means of descriptive commentary the history of the New York State Band Directors Association (NYSBDA) from its organization in 1980, up to and including the 30th anniversary of the Annual Symposium in March of 2011. After meticulous analysis of reports, documents and proceedings of the New York State Band Directors Association and organizing the information contained in these sources, the author has articulated in writing the major activities and labors of the organization. The author initiated the study by securing official permission from the 2010-2011 Executive Board of the New York State Band Directors Association. The author then followed the procedure of collecting data by contacting relevant personalities of the Association and requested that: (a) Association documents, (b) meeting minutes, (c) programs, (d) records, and (e) correspondence be transferred for evaluation. By means of thorough review and categorizing of materials a timeline of relevant events that described the formation and advancement of the Association was created. The New York State Band Directors Association was formed to satisfy a specific need for professional growth and support for instrumental music professionals working at all academic levels, public, private and community in New York State. The origin of the Association was in direct relation to the success of a weekend symposium in 1977 designed expressly for band directors. The NYSBDA grew from a small ‘steering committee’ under the leadership of Richard Snook. The group stated its primary purpose to be the improvement and promotion of instrumental music in New York State. Throughout its history, NYSBDA has provided assistance to instrumental music educators and band directors through its many initiatives. NYSBDA provides and exhibits: (a) professional growth opportunities by means of its annual symposium and regional workshops, (b) performance opportunities for instrumental ensembles, (c) potential for student participation in NYSBDA statewide honor bands, (d) instrumental teacher and professional recognition by means of awards, (e) the promotion of new literature by sponsoring and commissioning new band compositions, and (f) cooperation with other state associations. The Executive board and Membership of NYSBDA have demonstrated a commitment to the advancement and improvement of instrumental music and its professionals. This is in agreement and fulfillment with its stated Constitutional objectives. / School of Music

The detailed structure of the myofibrillar material in fibres from different muscles has been studied. Specimens have been obtained from human muscles and from different muscles frequently examined in experimental studies. Both light- and electron microscopical techniques have been used. Of central importance has been the method, which makes it possible to prepare ultrathin sections of frozen tissue, i.e. cryo-ult- ramicrotomy. A number of techniques for image analysis have been applied in order to obtain objektive data from the micrographs. In Paper I the present knowledge about muscle fibre structure, cryo-- sectioning and image analysis is summarized and relevant methodological problems are discussed. Paper II describes the detailed structure of the C-zone of the A-band and shows, above all, that structures occur with different repeats along the long axis of the myofibril. Paper III describes the subcellular organization of different fibres in a homogeneous (based on enzyme histochemical mATPase) population, and shows that different structural characteristies can vary independently of each other. Paper IV describes the structural diversity of the myofibrillar M-band, and paper V the diversity of the myofilament fine structure in different fibres. The results show that there is a most sophisticated, and previosly unrealized, structural specialization both within the myofibrils and between myofibrils from different fibres and muscles, even if the fibres are of the same fibre type. The findings suggest that generally used models, showing the structural organization within myofibrils and myofilaments, are oversimplifications. The fibre population is more heterogeneously built up than the common systems for fibre type classification makes one to belive. / <p>Diss.
