Summary of Dissertation Recitals Three Programs of Piano Music

1. First Dissertation Lecture Recital. “Thematic Development and Continuity in Sonata No. 1 in F Minor, Op. 6 by Alexander Scriabin.” Tuesday, January 22, 2013 at 8:00 pm in the Moore Building, Britton Recital Hall. The lecture explored how Scriabin’s Sonata No. 1 achieves continuity and unity of thematic development throughout the all the movements by using inter-related motivic ideas, and how his technique of transforming the character of the theme relates to the emotional and spiritual arc of the piece. 2. Second Dissertation Recital. Wednesday, March 20, 2013 in Britton Recital Hall, E. V. Moore Building. The recital program included Beethoven’s Piano Sonata No. 28 in A Major, Op. 101 and Sergei Rachmaninoff ‘s Piano Sonata No. 1 in D Minor, Op. 28. 3. Third Dissertation Recital. Tuesday, May 14, 2013 in Stamps Auditorium, Walgreen Drama Center. The recital featured Mozart’s Piano Sonata in E-flat Major, K. 282, Beethoven’s Piano Sonata No. 31, in A-flat Major, Op. 110 and Schumann’s Symphonic Etudes, the version of 1852.AMUMusic: PerformanceUniversity of Michigan, Horace H.

Comparison of very-large-scale motions of turbulent pipe and boundary layer simulations

A direct numerical simulation of a fully developed turbulent pipe flow was performed to investigate the similarities and differences of very-large-scale motions (VLSMs) to those of turbulent boundary layer (TBL) flows. The Reynolds number was set to ReD = 35 000, and the computational domain was 30 pipe radii in length. Inspection of instantaneous fields, streamwise two-point correlations, and population trends of the momentum regions showed that the streamwise length of the structures in the pipe flow grew continuously beyond the log layer (y/?? 3??), and the maximum length of the VLSMs increased up to ~30??. Such differences between the TBL and pipe flows arose due to the entrainment of large plumes of the intermittent potential flow in the TBL, creating break-down of the streamwise coherence of the structures above the log layer with the strong swirling strength and Reynolds shear stress. The average streamwise length scale of the pipe flow was approximately 1.5-3.0 times larger than that of the TBL through the log and wake regions. The maximum contribution of the structures to the Reynolds shear stress was observed at approximately 6?? in length, whereas that of the TBL was at 1??-2??, indicating a higher contribution of the VLSMs to the Reynolds shear stress in the pipe flow than in the TBL flow.open1

Current-Induced Resonant Motion of a Magnetic Vortex Core: Effect of Nonadiabatic Spin Torque

The current-induced resonant excitation of a magnetic vortex core is investigated by means of analytical and micromagnetic calculations. We find that the radius and the phase shift of the resonant motion are not correctly described by the analytical equations because of the dynamic distortion of a vortex core. In contrast, the initial tilting angle of a vortex core is free from the distortion and determined by the nonadiabaticity of the spin torque. It is insensitive to experimentally uncontrollable current-induced in-plane Oersted field. We propose that a time-resolved imaging of the very initial trajectory of a core is essential to experimentally estimate the nonadiabaticity.Comment: 4 pages, 4 figure
