My dissertation is a musical composition for a chamber ensemble of sixteen players, scored for flute and piccolo, oboe, clarinet in Bb, bassoon, horn in F, trumpet in Bb, trombone, percussion (2 players), piano, violin I, violin II, viola, violoncello, and double bass. It is specifically written for the University of Iowa Center for New Music Ensemble, and has been read by the ensemble twice to secure ideas for orchestration. The Revival of a Waning Moon is a single-movement work for approximately 15 minutes. The harmonic content of the work are derived from five hexachords that I labeled H-I through H-V: H-I [013478], H-II [012578], H-III [012468], H-IV [012567], and H-V [012479]. Even though all of the six chords are associated with each other to establish overall harmonic control, only H-II is cultivated for its thematic harmony. The subsets from the H-II, such as the trichord [015] and tetrachord [0157], produce melodic ideas and associates with other harmonies throughout the piece. Metric modulation is utilized between the sections where the rhythmic elements are emphasized. Jajinmori, a Korean traditional rhythmic pattern is employed to describe a Korean folk dance, which is typically performed in the moonlight. Brake drums and gongs are especially used for imitating the sonorities of Korean percussion instruments. Formally the work is comprised of three parts (ABA'). Each part has a few divisional sections, which are connected and incorporates each other in terms of their harmonic elements, but is developed with various rhythmic gestures in different tempi. My personal reception of visual images of the waning phase of the moon, more specifically between the waning crescent and new moon, is mainly a sense of loss, sorrow, loneliness, and anger. Do-Hyang Na (1902-1926), tragically and untimely died at a young age, also describes the waning crescent as an expelled princess and a regrettable widow despite of its beauty in his essay Geu-Meum-Dahl. The visual and poetic imageries provide the emotional background of the piece.

La conception basée composants est une nouvelle méthode de construction d'applications et de systèmes distribués. Cette conception par composition pose cependant plusieurs problèmes, dûs aux services non uniformes (dépendants d'un contexte) et aux liens dynamiques d'interconnexion entre les composants. Nous proposons un cadre formel pour la vérification compositionelle de tels systèmes. Nous définissons un langage de type d'interfaces comportementales, qui constitue un contrat comportemental pour le composant et son environnement. Le composant doit respecter ce contrat

ABSTRACT Rashomon, a composition for wind ensemble, portrays a musical eventthe simple motion of rise and fallfrom three different perspectives, each assigned to one of the three movements. The underlying form, the basic gestural content, pitch material and instrumentation remain the same in the three movements. Each movement consists of five sections: an introduction, a statement of melodic material, a trumpet statement of melodic material, an ascent to the highest point and a resolution. Rashomon has four main gestural components: compression/expansion, rise/fall, interruption or interjection and the stasis of sustain or residue. The gestural material develops gradually from the start of Rashomon I, where these ideas are introduced, through to the end of Rashomon III. Pitch movement in wind ensemble works structured for advanced secondary school or university wind ensembles needs to be sensitive to the difficulties inherent in the ensembles unfamiliarity with atonal patterns. Many instrumentalists at this level find that an increase in dissonance complicates their intonation and large intervallic leaps stretch their technical abilities. The pitch content of Rashomon takes these possible restrictions into consideration in order facilitate a quality performance while maintaining the pitch organization of a modernist work. The use of simple gestural components, perceptual similarity of form, combined with a driving and aggressive nature, aids in the accessibility of the work for the wind ensemble and its audience.

The Concerto for Bassoon and Chamber Orchestra is a three-movement composition for solo bassoon accompanied by an ensemble of modest proportions. This piece is composed in partial fulfillment of the requirements of the degree Master of Music with a concentration in Composition from the University of Tennessee, Knoxville. The Concerto was composed during the 2010-2011 academic year. This paper provides a narrative analysis of the Concerto in terms of the parameters of its musical content, and relationships thereof. In so doing, references are made to related or influential compositions of the last century in respect to genre, style, form, pitch content, rhythm, and orchestration.

Oat is an important crop for livestock feed and human food. Increased interest in the health promoting properties of oat has led to a need to explore diverse oat germplasm for improved nutritional quality. One target for improved nutritional quality could be an altered fatty acid composition. A study was conducted to explore the fatty acid profile of diverse accessions from the world oat collection preserved in the Canadian national seed genebank, Plant Gene Resources of Canada (PGRC), at the Agriculture and Agri-Food Canada (AAFC) Research Centre, Saskatoon, Saskatchewan, Canada and genotypes from the Crop Development Centre (CDC), University of Saskatchewan, Saskatoon and the Eastern Cereal and Oilseed Research Centre (ECORC), AAFC, Ottawa, Canada. Accessions included a wide range of Avena sativa L. and other selected species from the genus Avena (A. byzantina C. Koch, A. sterilis L., A. fatua L., A. sativa subsp. nudisativa (Husn.) Rod. et. Sold. and A. strigosa Schreb.). The fatty acid profiles of 917 oat accessions from these taxa were analyzed using gas chromatography, revealing significant variability for the three major fatty acids in oat oil. Oleic and linoleic acid demonstrated the greatest variation. A few A. sativa accessions had higher oleic and lower palmitic acid levels compared to the general average. Some hexaploid wild oat accessions (A. sterilis) showed relatively high oleic and below average levels of palmitic and linoleic acid compared to A. sativa. A. strigosa accessions had consistently higher levels of oleic acid than other Avena species. Based on initial results, 52 selected A. sativa accessions were grown in 2009 in replicated field trials and re-evaluated to gain insight into the influence of the growing environment on fatty acid composition. Fatty acid composition was affected by genotype, whereas location significantly affected palmitic and oleic acid content. Correlations were determined among the contents of the six fatty acids, oil content and protein content. Oleic acid content was positively correlated with oil content, which may be particularly important to plant breeders for nutritional quality improvement of future oat cultivars. The understanding gained from this research suggests the possibility of improving the fatty acid profile of future oat cultivars for food and feed.

Let T be the unit circle,(mu) be a Borel probability measure on T and (phi) be a bounded Lebesgue measurable function on T. in this paper we consider the weighted composition operator W(phi) on L^2(T,mu) defined by W(phi)f:=(phi)*(f(circle)(tau)), f in L^2(T), where (tau) is the map (tau)(z)=z^2, z in T. We will study the von Neumann-Wold decomposition of W(phi) when W(phi) is an isometry and (mu)<< m,where m is the normalized Lebesgue measure on T.

The goal of the present research is to collect basic data for a study on the species composition and spatiotemporal distribution of pycnogonida (sea spider) in the Port of Kaohsiung. We used collecting net to collect samples from 8 stations within the Port of Kaohsiung during a 15-month period from March 2007 to May 2008. all pycnogonids collected were identified, if possible to species level, counted, and measured. There were eight taxa of pycnogonids in our collection belonging to four family and seven genera, including: Achelia japonica with rounded trunk and pyramid proboscis, Ammothella sp. with palp and degrade chelifore, Tanystylum duospinum with rounded trunk which bears color stripes in live specimens, Callipallene amaxana with large and functional chelifore, Pigrogromitus timsanus with robust and short walking lags, Anoplodactylus spp.1and 2 without auxiliary claws, and Endeis sp. with elongate trunk and without cephalic appendages. The average monthly catch of pycnogonid specimens from the Port of Kaoshiung in our collection was 111.4. Ammothella sp. was the most dominant taxon, contributing to 37.8% of the total collection while Anoplodactylus sp.2 was the laest abundant taxon, amounting to only 0.2¢H of the total number. Monthly catch of pycnogonids was not significantly different between months but significantly different between stations. Significant length difference between sex was noted in Ammothella sp.¡BC. amaxana¡BAnoplodactylus sp.1 and Endeis sp(P<0.05) and significant difference in monthly body length was found in T.duospinum and A. japonica (P<0.05).
