Tracer-Independent Approaches to Stratosphere-Troposphere Exchange and Tropospheric Air Mass Composition
… the stratospheric mean residence time and the mass fraction of the stratosphere in any given residence-time interval. For the idealized model we find that air exiting the stratosphere in the winter hemisphere has significantly longer mean residence times than air exiting in the summer …

Mass, Composition, Source Identification and Impact Assessment for Fine and Coarse Atmospheric Particles in the Desert Southwest
… our understanding of ambient concentrations and composition in rural, arid environments. Detailed measurement of ambient fine and coarse mass, ion, metal, and carbon concentrations at one-in-six day resolution was conducted at three sites from February 2009 to February 2010. Detailed organic …

A Study of the Selected Masses of Twentieth-Century Black Composers: Margaret Bonds, Robert Ray, George Walker, and David Baker
… composers. Each of the composers has written a mass composition. The composers were selected because of their diversity in composition. Two of the composers (Margaret Bonds and George Walker) have written mass compositions that reflect no real ethnic influence. The compositions by Robert Ray and …

Gyorgy Orban's Mass Compositions (1989--1999): An Analysis of Masses 1,5, and 9
… dissertation will examine three of the eleven masses composed by Gyorgy Orban (b. 1947) between 1989 and 1999---Mass No. 1 (1989), the Missa Quinta (1992), and Mass No. 9 (1999). These three masses represent one-half of the six masses that are currently published. As representative works …

A methodology for the heat of immersion as a measure of wettability of mineral mixtures
… and desired. The surface area fraction or mass composition can be used to create the linear relationship between the heat of immersion and the composition of the binary mineral mixture. It was shown that there is a linear relationship between the heat of immersion and mass composition or …

Probing giant-planet forming zones around Solar-like stars with CO
… where planets are formed. The evolution and composition of protoplanetary disks determine the time, environments and materials available for planet formation. However fundamental properties of protoplanetary disks such as mass, composition, and the angular momentum transfer mechanism are …

Top-Down Interrogation And Characterization Of Biological Macromolecules
<p>Analytical mass spectrometry has been widely applied in the field of biomolecule identification and characterization. It provides fast, accurate and robust information relevant to the molecular mass, composition and structure of the target analytes.</p> <p>This thesis is focused on the top-down …

Sub-grid process analysis of the sensitivity of black carbon aging to particle microphysical properties at emission
… contains only a single species or a homogeneous composition for all particles of a given mode or size. In this study, we use the particle-resolved aerosol model PartMC-MOSAIC to assess the aging mechanisms of black carbon-containing particles of varied initial size. PartMC-MOSAIC explicitly …

On the Application of Machine Learning to Planetary Sciences
… is found to profoundly affect the predicted mass, composition, and internal structure of terrestrial planets with respect to previous studies that assumed perfectly inelastic collisions (perfect merging). In Chapters 4 and 5, a novel approach that combines machine learning and Bayesian …

IDENTIFICATION OF ELECTROREFINER AND CATHODE PROCESSING FAILURE MODES AND DETERMINATION OF SIGNATURE-SIGNIFICANCE FOR INTEGRATION INTO A SIGNATURE BASED SAFEGUARDS FRAMEWORK FOR PYROPROCESSING
… code named ERAD capable of modeling the mass transport of metals within an electrorefiner. The second model was an MCNP-based simulation of the Canberra JCC-31 High Level Neutron Coincidence Counter. First, the identified failure modes were simulated by changing ERAD inputs. ERAD …
