Description: Historically, wireless communication devices have been developed to process one specific waveform. In contrast, a modern cellular phone supports multiple waveforms corresponding to LTE, WCDMA(3G) and 2G standards. The selection of the network is controlled by software running on a general purpose processor, not by the user. Now, instead of selecting from a set of complete radios as in software controlled radio, what if the software could select the building blocks based on the user needs. This is the new software-defined flexible radio which would enable users to construct wireless systems that fit their needs, rather than forcing to use ...

Description: A dual chamber molecular beam epitaxy (MBE) system was rebuilt for the growth of 6.1 Angstrom II-VI and III-V compound semiconductor materials that are to be used in novel optoelectronic devices that take advantage of the nearly continuous bandgap availability between 0 eV and 3.4 eV. These devices include multijunction solar cells and multicolor detectors. The MBE system upgrade involved the conversion of a former III-V chamber for II-VI growth. This required intensive cleaning of the chamber and components to prevent contamination. Special features including valved II-VI sources and the addition of a cold trap allowed for the full system ...

Description: ABSTRACT Stress and burnout in the educational field primarily in teaching is not a new phenomenon. A great deal of research and analysis to the contributing factors of causation to teacher burnout has been executed and analyzed. The struggle of the artist/teacher, hybrid professionals that maintain two concurrent roles, offers a perspective to burn out that has gone unnoticed. The conflict of roles for the artist/teacher does not infer that the teacher role is incapable of reconciling with the artist role but because of this unique scenario the stories of art teachers and burnout often go unheard. Today's public educator ...

Description: John Harbison is one of the most prominent composers of the twentieth and twenty-first centuries. He has made major contributions in all areas of classical music, including operas, symphonies, chamber music, choral works, and vocal pieces.Among his vast output is 'Four Songs of Solitude,' his only composition (to date) for solo violin. Though the piece is beautiful and reflective in nature, its inherent technical and musical difficulties present challenges to violinists preparing the piece. There is no published edition of 'Four Songs of Solitude' that includes bowings and fingerings, and violinists used to practicing and performing the études and repertoire ...

Description: Leprosy and tuberculosis are age-old diseases that have tormented mankind and left behind a legacy of fear, mutilation, and social stigmatization. Today, leprosy is considered a Neglected Tropical Disease due to its high prevalence in developing countries, while tuberculosis is highly endemic in developing countries and rapidly re-emerging in several developed countries. In order to eradicate these diseases effectively, it is necessary to understand how they first originated in humans and whether they are prevalent in nonhuman hosts which can serve as a source of zoonotic transmission. This dissertation uses a phylogenomics approach to elucidate the evolutionary histories of the ...

Description: Soft magnetic alloys play a significant role for magnetic recording applications and highly sensitivity magnetic field sensors. In order to sustain the magnetic areal density growth, development of new synthesis techniques and materials is necessary. In this work, the effect of oxygen incorporation during electrodeposition of CoFe alloys on magnetic properties, magnetoresistance and structural properties has been studied. Understanding the magnetic properties often required knowledge of oxygen distribution and structural properties of the grown films. Transmission electron microscopy (TEM) was a powerful tool in this study to correlate the oxygen-distribution nanostructure to the magnetic properties of deposited films. Off-axis electron ...

Description: Child development scholars have demonstrated a host of negative outcomes of child physical abuse, including emotional problems, delinquency, and future victimization. However, it is unclear if child physical abuse during childhood is related to subsequent violent victimization during youth and young adulthood. Building on routine activity theory and prior research, and using data collected from 2,245 individuals in Changzhi, China, this study examines if the experience of child physical abuse is positively related to violent victimization in youth and young adulthood, and if the relationship between child physical abuse and violent victimization is mediated by an individual’s routine activities. The ...

Description: Zwischen in the German language means `between,' and over the past century, as operatic voices have evolved in both range and size, the voice classification of Zwischenfach has become much more relevant - particularly to the female voice. Identifying whether nineteenth century composers recognized the growing opportunities for vocal drama, size, and range in singers and therefore wrote roles for `between' singers; or conversely whether, singers began to challenge and develop their voices to sing the new influx of romantic, verismo and grand repertoire is difficult to determine. Whichever the case, teachers and students should not be surprised about the ...

Description: The growing use of synthetic population, which is a disaggregate representation of the population of an area similar to the real population currently or in the future, has motivated the analysis of its sensitivity in the population generation procedure. New methods in PopGen have enhanced the generation of synthetic populations whereby both household-level and person-level characteristics of interest can be matched in a computationally efficient manner. In the process of set up, population synthesis procedures need sample records for households and persons to match the marginal totals with a specific set of control variables for both the household and person ...

Description: ABSTRACT School districts in the United States have undergone large changes over the last decade to accommodate No Child Left Behind (NCLB). Arizona accommodated NCLB through Arizona's Instrument to Measure Standards (AIMS). Expectations were established for all students, varying by group of students based on grade, special education status, free/reduced lunch status, and English Language Learner (ELL) status. AIMS performance for subgroups has been scrutinized, due to the high stakes for schools and districts to meet expectations. This study is interested in the performance of ELL students, when compared with non-ELL students. The current study investigated AIMS performance of students ...
