The primary reason for the wireless technology evolution is towards building capacity and obtaining higher data rates. Enclosed locations, densely populated campus, indoor offices, and device-to-device communication will require radios that need to operate at data rates up to 10 Gbps. In the next few years, a new generation of communication systems would emerge to better handle the ever-increasing demand for much wider bandwidth requirements. Simultaneously, key factors such as size, cost, and energy consumption play a distinctive role towards shaping the success of future wireless technologies. In the perspective of 3GPP 5G next generation wireless communication systems, the X band was explicitly targeted with a vast range of applications in point to point radio, point to multi point radio, test equipment, sensors and future wireless communication. An X-band RF front-end circuit for next generation wireless network applications is presented in this work. It details the design of a low noise amplifier and a power amplifier for X band operation. The designed amplifiers were integrated with a wideband single-pole-double-throw switch to achieve an overall front-end structure for 10 GHz. The design was carried out and sent for fabrication using a GaN 0.15µm process provided by NRC, a novel design kit. Due to higher breakdown voltage, high power density, high efficiency, high linearity and better noise performance, GaN HEMTs are a suitable choice for future wireless communication. Thus, the assumption is to further explore capabilities of this process in front-end design for future wireless communications.

In general, Dual-Band technology enables microwave components to work at two different frequencies. This thesis introduces novel dual-band microwave components and their applications. Chapter 2 presents a novel compact dual-band balun (converting unbalanced signals to balanced ones). The ratio between two working frequencies is analyzed. A novel compact microstrip crossover (letting two lines to cross each other with very high isolation) and its dual-band application is the subject of chapter 3. A dual-frequency cloak based on lumped LC-circuits is introduced in chapter 4. In chapter 5, a dual-band RF device to detect dielectric constant changes of liquids in polydimethylsiloxane (PDMS) microfluidic channels has been presented. Such a device is very sensitive, and it has significantly improved the stability. Finally, conclusion of this thesis and future works are given in chapter 6.

The primary purpose of this research paper was to study performance anxiety among middle school students during a sight-reading audition. Furthermore, this sutdy asks whether the manner in which directions are presented by the sight-reading adjudicator during the course of an audition has significant impact on the performance outcome. Participants (n=75) were middle school students attending a highly rated band program in the Miami-Dade County (Miami, FL) area. By use of investigator-derived surveys, levels of trait and state anxiety were determined before and after the sight-reading performance. Means and standard deviations were calculated for perceived anxiety and for the resulting scores of the performance. A t-testcompared the control and experimental groups perceived level of anxiety, where statistically significant results were found at the pp

Plants possess unique features in many aspects of development. One of these features is seen in cell wall placement during cytokinesis, which is determined by the position of the preprophase band (PPB) and the subsequent expansion of the phragmoplast that deposits the new cell wall. During phragmoplast expansion, the phragmoplast tracks to the cortical division site, which was delineated by the PPB. Thus the position of the PPB determines the orientation of the division plane. In Arabidopsis thaliana, TONNEAU2 (TON2) is required for PPB formation and has been shown to interact with a type A subunit of the PP2A phosphatase in the yeast two-hybrid system. In Arabidopsis tonneau2 (ton2) mutants, abnormalities of the cortical microtubule cytoskeleton, such as disorganization of the interphase microtubule array and lack of PPB formation before mitosis markedly affects cell shape and arrangement as well as overall plant morphology. Loss of dcd1/add1, the maize ton2 homologues gives rise to a similar phenotype in Zea mays. The TON2 protein has two EF hand domains which are calcium-binding sites. Since calcium has been known to play key roles in several areas of plant functioning, the following question was raised: “Does calcium binding contribute to the localization and function of TONNEAU at the PPB?” To address this question, a series of constructs were generated to determine if TON2 binds calcium. Additionally, Ca2+ binding sites were mutated in constructs containing the TON2 gene fused to GFP or YPF. These constructs were then transformed into ton2 mutant plants and the localization of TON2 fusion protein and whether the construct is capable of rescuing the mutant phenotype were observed. Although, localization of TON2 to the PPB was not observed, the presence of the constructs were confirmed in the transformed plants using selection markers and by observing fluorescence under a confocal microscope.

Paul Robert Fauchet's Symphonie pour Musique d'Harmonie, known in the United States as Symphony in B-flat, is a four-movement composition spanning nearly thirty minutes in length and written in the style of the late romantic composers. Despite its place as one of the first symphonies for wind band, a performance of the piece that represents the composer's 1926 orchestration is difficult due to the inclusion of instruments that are no longer in common practice, including bugles, alto horns, and saxhorns. Later American editions of the work by James Robert Gillette (1933) and Frank Campbell-Watson (1948/1949) replaced these instruments, but also took several other liberties with orchestration and voicing. The primary purpose of this study was the creation of a performance edition of the Symphony for modern wind band that is accessible to a larger audience of performers and listeners. The method involved in creating the modern edition eliminates errors of extant editions and clarifies a number of the discrepancies surrounding the symphony's multiple publications. This edition attempts to retain the composer's voicing and orchestration choices. To accomplish this, the present project considered where modern instrumentation differed from the original sources and attempted to balance timbral similarities between those instruments, while also considering ease of comprehension for a modern ensemble to perform the work. Sources used to create this edition included all published editions of scores and parts, as well as a newly created full score of the 1926 printed parts. The study concludes with the inclusion of the full score of the new performance edition.

Students learn more from their band experience than musical concepts. Many students learn leadership skills as a part of their time in band, but these skills are rarely an official part of the curriculum. Additonally, band directors must use leadership to successfully build and guide their program, but are rarely provided formal training in leadership theory and skills. I used transformational leadership (Bass & Riggio, 2006; Burns, 1978) as a framework to examine practices band directors use to learn leadership themselves and help students develop their own leadership. I utilized Deci and Ryan’s (2000) Self-Determination Theory (SDT) and autonomy supports (1995) to help identify director practices that were transformative in nature. Through the use of interviews with three band directors and ten students I examined how band directors learn leadership, how they use it, and how students in band understand the use of leadership by directors and themselves. I found that band directors typically learn these transformative skills through a variety of formal and informal situations through life starting as early as high school. Directors develop leadership skills through the presence of mentors and the use of critical self-reflection over the course of their careers. Directors create a culture of band that is extended to the student body and reinforced through student leadership and peer mentoring. Finally, managerial tasks can be used to help students develop leadership identities (Komives et al., 2005), develop leadership skills, and allow them to act as transformative figures themselves.

This work deals with properties and physical phenomena occurring in semiconductor materials. In details are described generation - recombination processes in a state of thermodynamic disequilibrium. The output of work is a software application simulating waveforms of energy levels in the band's own models and impurity semiconductors, depending on the type of semiconductor, impurities concentration and temperature. Finally, the processed virtual lab experiment deliverable in the educational process.

As Darkness Falls is a composition that explores our interaction with several aspects of darkness through the use of musical imagery. The imagery attempts to reflect the moods, feelings, and impressions of a person as he or she interacts with darkness. The non-programmatic character of the composition allows listeners to superimpose their own experiences onto the musical tapestry in order to manifest a personal connection between the listener and the music. As Darkness Falls is a composition scored for a minimum instrumentation of piccolo, 6 flutes, 3 oboes, 3 bassoons, 9 B-flat clarinets, B-flat bass clarinet, 2 E-flat alto saxophones, B-flat tenor saxophone, E-flat baritone saxophone, 4 B-flat trumpets, 4 horns in F, 3 tenor trombones, bass trombone, 2 euphoniums, 2 tubas, timpani, and 4 percussionists. The music consists of three movements (slow-slow-fast) lasting a total of approximately seventeen minutes. The duration of each of the three movements is six minutes, four and one-half minutes, and six and one-half minutes, respectively. The document also contains an analysis of the work by the composer. The analysis explores the compositional style of the work, focusing on musical aspects within each movement that were governing parameters in the compositional process.

Submitted to the Faculty of Education in fufilment of the requirements for the degree of Doctor of Education in the Department of Curriculum & Instructional Studies at the University of Zululand, 2006. / The present study examines educators' experiences in implementing the Revised National Curriculum Statement in the GET Band. The first aim of the study was to ascertain the nature of educators' experiences in implementing the Revised National Curriculum Statement. The second aim was to determine whether educators' biographical factors such as gender, age, teaching experience, qualification and rank have any influence on the nature of their experiences in implementing the Revised Curriculum Statement. The third aim was to ascertain the extent to which educators generally find implementing the Revised National Curriculum Statement to be stressful. The last aim was to determine whether educators' biographical factors (gender, age, teaching experience, qualification and rank) have any influence on the extent to which they generally find implementing the Revised National Curriculum Statement to be stressful. To this end, a questionnaire was administered to a randomly selected sample of three hundred and eight educators. The findings reveal that educators differ in terms of the nature of their experiences in implementing the Revised Curriculum Statement. A high percentage (61.04%) of educators reports a positive experience about implementing the Revised National Curriculum Statement. The findings also show that age, teaching experience and qualification have an influence on the nature of educators' experiences in implementing the Revised National Curriculum Statement. The findings further reveal that educators differ in the extent to which they generally find implementing the Revised National Curriculum Statement to be stressful. A relatively higher percentage (38.31%) report above average level of stress, 28.90% report below average level and 32.79% report an average level The last finding shows that educators' gender, age, teaching experience, qualification and rank have no influence on the extent to which educators generally find implementing the Revised National Curriculum Statement to be stressful. On the basis of the findings of this study, a model on curriculum implementation process was proposed and recommended.

Since the early sixteenth century, the bassoon has played a role of varying importance in musical organizations. Early groups used as many as twenty-four bassoons in conjunction with other instruments. Today, it is common to have no more than two or three bassoons in bands and orchestras because other instruments, as they developed, have replaced the bassoon in the instrumentation of such groups. Although the bassoon is not as important numerically as it formerly was, its place in musical organizations is assured because it has expressive colors and tonal qualities which cannot be duplicated by any other instrument. The bassoon is especially important as a bass instrument in small ensembles.
